Summary At the end of their life, stars spread their inner material into the diffuse interstellar medium. This diffuse medium gets locally denser and form dark clouds (also called dense or molecular clouds) whose innermost part is shielded from the external UV field by the dust, allowing for molecules to grow and get more complex. Gravitational collapse occurs inside these dense clouds, forming protostars and their surrounding disks, and eventually planetary systems like (or unlike) our solar system. The formation and evolution of molecules, minerals, ices and organics from the diffuse medium to planetary bodies, their alteration or preservation throughout this cosmic chemical history set the initial conditions for building planets, atmospheres and possibly the first bricks of life. The current view of interstellar chemistry is based on fragmental works on key steps of the sequence that are observed. The objective of this proposal is to follow the fractionation of the elements between the gas-phase and the interstellar grains, from the most diffuse medium to protoplanetary disks, in order to constrain the chemical composition of the material in which planets are formed. The potential outcome of this project is to get a consistent and more accurate description of the chemical evolution of interstellar matter. To achieve this objective, I will improve our chemical model by adding new processes on grain surfaces relevant under the diffuse medium conditions. This upgraded gas-grain model will be coupled to 3D dynamical models of the formation of dense clouds from diffuse medium and of protoplanetary disks from dense clouds. The computed chemical composition will also be used with 3D radiative transfer codes to study the chemical tracers of the physics of protoplanetary disk formation. The robustness of the model predictions will be studied with sensitivity analyses. Finally, model results will be confronted to observations to address some of the current challenges.

Project Search for a fourth neutrino with a PBq anti-neutrino source
Researcher (PI) Thierry Michel René Lasserre
Host Institution (HI) COMMISSARIAT A L ENERGIE ATOMIQUE ET AUX ENERGIES ALTERNATIVES
Call Details Starting Grant (StG), PE2, ERC-2012-StG_20111012
Summary Several observed anomalies in neutrino oscillation data can be explained by a hypothetical fourth neutrino separated from the three standard neutrinos by a squared mass difference of a few eV2. This hypothesis can be tested with a PBq (ten kilocurie scale) 144Ce antineutrino beta-source deployed at the center of a large low background liquid scintillator detector, such like Borexino, KamLAND, and SNO+. In particular, the compact size of such a source could yield an energy-dependent oscillating pattern in event spatial distribution that would unambiguously determine neutrino mass differences and mixing angles.
The proposed program aims to perform the necessary research and developments to produce and deploy an intense antineutrino source in a large liquid scintillator detector. Our program will address the definition of the production process of the neutrino source as well as its experimental characterization, the detailed physics simulation of both signal and backgrounds, the complete design and the realization of the thick shielding, the preparation of the interfaces with the antineutrino detector, including the safety and security aspects.

Researcher (PI) Pascal Yiou
Host Institution (HI) COMMISSARIAT A L ENERGIE ATOMIQUE ET AUX ENERGIES ALTERNATIVES
Call Details Advanced Grant (AdG), PE10, ERC-2013-ADG
Summary "The A2C2 project treats two major challenges in climate and atmospheric research: the time dependence of the climate attractor to external forcings (solar, volcanic eruptions and anthropogenic), and the attribution of extreme climate events occurring in the northern extra-tropics. The main difficulties are the limited climate information, the computer cost of model simulations, and mathematical assumptions that are hardly verified and often overlooked in the literature.
A2C2 proposes a practical framework to overcome those three difficulties, linking the theory of dynamical systems and statistics. We will generalize the methodology of flow analogues to multiple databases in order to obtain probabilistic descriptions of analogue decompositions.
The project is divided into three workpackages (WP). WP1 embeds the analogue method in the theory of dynamical systems in order to provide a metric of an attractor deformation in time. The important methodological step is to detect trends or persisting outliers in the dates and scores of analogues when the system yields time-varying forcings. This is done from idealized models and full size climate models in which the forcings (anthropogenic and natural) are known.
A2C2 creates an open source toolkit to compute flow analogues from a wide array of databases (WP2). WP3 treats the two scientific challenges with the analogue method and multiple model ensembles, hence allowing uncertainty estimates under realistic mathematical hypotheses. The flow analogue methodology allows a systematic and quasi real-time analysis of extreme events, which is currently out of the reach of conventional climate modeling approaches.
The major breakthrough of A2C2 is to bridge the gap between operational needs (the immediate analysis of climate events) and the understanding long-term climate changes. A2C2 opens new research horizons for the exploitation of ensembles of simulations and reliable estimates of uncertainty."

Project Computational design of novel protein function in antibodies
Researcher (PI) Sarel-Jacob Fleishman
Host Institution (HI) WEIZMANN INSTITUTE OF SCIENCE
Call Details Starting Grant (StG), LS1, ERC-2013-StG
Summary We propose to elucidate the structural design principles of naturally occurring antibody complementarity-determining regions (CDRs) and to computationally design novel antibody functions. Antibodies represent the most versatile known system for molecular recognition. Research has yielded many insights into antibody design principles and promising biotechnological and pharmaceutical applications. Still, our understanding of how CDRs encode specific loop conformations lags far behind our understanding of structure-function relationships in non-immunological scaffolds. Thus, design of antibodies from first principles has not been demonstrated. We propose a computational-experimental strategy to address this challenge. We will: (a) characterize the design principles and sequence elements that rigidify antibody CDRs. Natural antibody loops will be subjected to computational modeling, crystallography, and a combined in vitro evolution and deep-sequencing approach to isolate sequence features that rigidify loop backbones; (b) develop a novel computational-design strategy, which uses the >1000 solved structures of antibodies deposited in structure databases to realistically model CDRs and design them to recognize proteins that have not been co-crystallized with antibodies. For example, we will design novel antibodies targeting insulin, for which clinically useful diagnostics are needed. By accessing much larger sequence/structure spaces than are available to natural immune-system repertoires and experimental methods, computational antibody design could produce higher-specificity and higher-affinity binders, even to challenging targets; and (c) develop new strategies to program conformational change in CDRs, generating, e.g., the first allosteric antibodies. These will allow targeting, in principle, of any molecule, potentially revolutionizing how antibodies are generated for research and medicine, providing new insights on the design principles of protein functional sites.

Project Exploring the diagnostics market for simple and fast point-of-care antibody detection
Researcher (PI) M MERKX
Host Institution (HI) TECHNISCHE UNIVERSITEIT EINDHOVEN
Call Details Proof of Concept (PoC), PC1, ERC-2013-PoC
Summary Antibody detection assays are used in many fields of biomedicine including the diagnosis of infectious diseases, autoimmune diseases and allergies. Current analytical techniques for antibody detection come with intrinsic limitations such as the requirement for multiple time-consuming incubation steps, multiple reagents, and/or sophisticated equipment. Supported by an ERC consolidator grant we have developed a highly modular sensor concept for antibody-responsive reporter enzymes (AbSens) that addresses many of these challenges. Key advantages include the ability to monitor antibodies directly in solution, easy read-out based on a simple color reaction, adaptability to target any antibody of interest, and high affinity and specificity. We believe that this generic sensor platform could find applications in low-cost point-of-care diagnostics, clinical research, and the development of therapeutic antibodies.
The goal of AbSens is to identify those opportunities in the huge market of antibody-based diagnostics where our sensor platform provides unique advantages over existing technologies, both in terms of analytical performance and economics.
To enable the next step towards commercialization, the analytical performance of our technology will be compared to current gold standards using relevant clinical samples in collaboration with commercial parties and clinicians. Other commercially important parameters are the long-term stability of the assay components and the development of a yeast-based production system to lower the cost of enzyme production. Based on an in-depth market analysis and the feedback we receive from external stakeholders on the performance of our technology, a realistic strategy will be developed for the further commercialization. In anticipation of exploring the commercialization of our AbSens technology we filed a US provisional patent application in Sept. 2012 on the key underlying technology, which was recently continued via the PCT route.

Project Elucidating the Causes and Effects of Atlantic Circulation Changes through Model-Data Integration
Researcher (PI) Claire Waelbroeck
Host Institution (HI) CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE CNRS
Call Details Advanced Grant (AdG), PE10, ERC-2013-ADG
Summary Rapid changes in ocean circulation and climate have been observed in marine sediment and ice cores, notably over the last 60 thousand years (ky), highlighting the non-linear character of the climate system and underlining the possibility of rapid climate shifts in response to anthropogenic greenhouse gas forcing.
To date, these rapid changes in climate and ocean circulation are still not fully explained. Two main obstacles prevent going beyond the current state of knowledge:
- Paleoclimatic proxy data are by essence only indirect indicators of the climatic variables, and thus can not be directly compared with model outputs;
- A 4-D (latitude, longitude, water depth, time) reconstruction of Atlantic water masses over the past 40 ky is lacking: previous studies have generated isolated records with disparate timescales which do not allow the causes of circulation changes to be identified.
Overcoming these two major limitations will lead to major breakthroughs in climate research. Concretely, I will create the first database of Atlantic deep-sea records over the last 40 ky, and extract full climatic information from these records through an innovative model-data integration scheme using an isotopic proxy forward modeling approach. The novelty and exceptional potential of this scheme is twofold: (i) it avoids hypotheses on proxy interpretation and hence suppresses or strongly reduces the errors of interpretation of paleoclimatic records; (ii) it produces states of the climate system that best explain the observations over the last 40 ky, while being consistent with the model physics.
Expected results include:
• The elucidation of the mechanisms explaining rapid changes in ocean circulation and climate over the last 40 ky,
• Improved climate model physics and parameterizations,
• The first projections of future climate changes obtained with a model able to reproduce the highly non linear behavior of the climate system observed over the last 40 ky.

Summary Our body is colonized by complex microbial communities (our microbiome) that are most abundant in the intestinal tract where they contribute significantly to our health and disease. It has been established that aberrations in our microbiome are of particular importance in obesity, type 2 diabetes and metabolic syndrome, rapidly growing diseases with a drug market volume of over 5 B$ per year. We have discovered in the ERC project Microbes Inside that a particular bacterium is able to modify the intestinal microbiome and may be used to develop a new approach to treat these and other metabolic diseases. The Proof of Concept project ACOM aims to confirm the commercial and technological feasibility of this approach, consolidate and expand our IP position, and develop a product development plan. These form the elements of a business plan that is expected to result in establishing a spin out company (ACOM).

Project Computational Foundations of Anthropomorphic Action
Researcher (PI) Jean Paul Laumond
Host Institution (HI) CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE CNRS
Call Details Advanced Grant (AdG), PE7, ERC-2013-ADG
Summary Actanthrope intends to promote a neuro-robotics perspective to explore original models of anthropomorphic action. The project targets contributions to humanoid robot autonomy (for rescue and service robotics), to advanced human body simulation (for applications in ergonomics), and to a new theory of embodied intelligence (by promoting a motion-based semiotics of the human action).
Actions take place in the physical space while they originate in the –robot or human– sensory-motor space. Geometry is the core abstraction that makes the link between these spaces. Considering that the structure of actions inherits from that of the body, the underlying intuition is that actions can be segmented within discrete sub-spaces lying in the entire continuous posture space. Such sub-spaces are viewed as symbols bridging deliberative reasoning and reactive control. Actanthrope argues that geometric approaches to motion segmentation and generation as promising and innovative routes to explore embodied intelligence:
- Motion segmentation: what are the sub-manifolds that define the structure of a given action?
- Motion generation: among all the solution paths within a given sub-manifold, what is the underlying law that makes the selection?
In Robotics these questions are related to the competition between abstract symbol manipulation and physical signal processing. In Computational Neuroscience the questions refer to the quest of motion invariants. The ambition of the project is to promote a dual perspective: exploring the computational foundations of human action to make better robots, while simultaneously doing better robotics to better understand human action.
A unique “Anthropomorphic Action Factory” supports the methodology. It aims at attracting to a single lab, researchers with complementary know-how and solid mathematical background. All of them will benefit from unique equipments, while being stimulated by four challenges dealing with locomotion and manipulation actions.

Summary The active target and time projection chamber (ACTAR TPC) is a novel gas-filled detection system that will permit new studies into the structure and decays of the most exotic nuclei. The use of a gas volume that acts as a sensitive detection medium and as the reaction target itself (an “active target”) offers considerable advantages over traditional nuclear physics detectors and techniques. In high-energy physics, TPC detectors have found profitable applications but their use in nuclear physics has been limited. With the ACTAR TPC design, individual detection pad sizes of 2 mm are the smallest ever attempted in either discipline but is a requirement for high-efficiency and high-resolution nuclear spectroscopy. The corresponding large number of electronic channels (16000 from a surface of only 25×25 cm) requires new developments in high-density electronics and data-acquisition systems that are not yet available in the nuclear physics domain. New experiments in regions of the nuclear chart that cannot be presently contemplated will become feasible with ACTAR TPC.

Summary "Computer vision is concerned with the automated interpretation of images and video streams. Today's research is (mostly) aimed at answering queries such as ""Is this a picture of a dog?"", (classification) or sometimes ""Find the dog in this photo"" (detection). While categorisation and detection are useful for many tasks, inferring correct class labels is not the final answer to visual recognition. The categories and locations of objects do not provide direct understanding of their function i.e., how things work, what they can be used for, or how they can act and react. Such an understanding, however, would be highly desirable to answer currently unsolvable queries such as ""Am I in danger?"" or ""What can happen in this scene?"". Solving such queries is the aim of this proposal.
My goal is to uncover the functional properties of objects and the purpose of actions by addressing visual recognition from a different and yet unexplored perspective. The main novelty of this proposal is to leverage observations of people, i.e., their actions and interactions to automatically learn the use, the purpose and the function of objects and scenes from visual data. The project is timely as it builds upon the two key recent technological advances: (a) the immense progress in visual recognition of objects, scenes and human actions achieved in the last ten years, as well as (b) the emergence of a massive amount of public image and video data now available to train visual models.
ACTIVIA addresses fundamental research issues in automated interpretation of dynamic visual scenes, but its results are expected to serve as a basis for ground-breaking technological advances in practical applications. The recognition of functional properties and intentions as explored in this project will directly support high-impact applications such as detection of abnormal events, which are likely to revolutionise today's approaches to crime protection, hazard prevention, elderly care, and many others."

Project Algorithms for coping with uncertainty and intractability
Researcher (PI) Nikhil Bansal
Host Institution (HI) TECHNISCHE UNIVERSITEIT EINDHOVEN
Call Details Consolidator Grant (CoG), PE6, ERC-2013-CoG
Summary The two biggest challenges in solving practical optimization problems are computational intractability, and the presence
of uncertainty: most problems are either NP-hard, or have incomplete input data which
makes an exact computation impossible.
Recently, there has been a huge progress in our understanding of intractability, based on spectacular algorithmic and lower bound techniques. For several problems, especially those with only local constraints, we can design optimum
approximation algorithms that are provably the best possible.
However, typical optimization problems usually involve complex global constraints and are much less understood. The situation is even worse for coping with uncertainty. Most of the algorithms are based on ad-hoc techniques and there is no deeper understanding of what makes various problems easy or hard.
This proposal describes several new directions, together with concrete intermediate goals, that will break important new ground in the theory of approximation and online algorithms. The particular directions we consider are (i) extend the primal dual method to systematically design online algorithms, (ii) build a structural theory of online problems based on work functions, (iii) develop new tools to use the power of strong convex relaxations and (iv) design new algorithmic approaches based on non-constructive proof techniques.
The proposed research is at the
cutting edge of algorithm design, and builds upon the recent success of the PI in resolving several longstanding questions in these areas. Any progress is likely to be a significant contribution to theoretical
computer science and combinatorial optimization.

makes an exact computation impossible.
Recently, there has been a huge progress in our understanding of intractability, based on spectacular algorithmic and lower bound techniques. For several problems, especially those with only local constraints, we can design optimum
approximation algorithms that are provably the best possible.
However, typical optimization problems usually involve complex global constraints and are much less understood. The situation is even worse for coping with uncertainty. Most of the algorithms are based on ad-hoc techniques and there is no deeper understanding of what makes various problems easy or hard.
This proposal describes several new directions, together with concrete intermediate goals, that will break important new ground in the theory of approximation and online algorithms. The particular directions we consider are (i) extend the primal dual method to systematically design online algorithms, (ii) build a structural theory of online problems based on work functions, (iii) develop new tools to use the power of strong convex relaxations and (iv) design new algorithmic approaches based on non-constructive proof techniques.
The proposed research is at the
cutting edge of algorithm design, and builds upon the recent success of the PI in resolving several longstanding questions in these areas. Any progress is likely to be a significant contribution to theoretical
computer science and combinatorial optimization.

Summary "During the twentieth century, the development of macroscopic engineering has been largely stimulated by progress in digital prototyping: cars, planes, boats, etc. are nowadays designed and tested on computers. Digital prototypes have progressively replaced actual ones, and effective computer-aided engineering tools have helped cut costs and reduce production cycles of these macroscopic systems.
The twenty-first century is most likely to see a similar development at the atomic scale. Indeed, the recent years have seen tremendous progress in nanotechnology - in particular in the ability to control matter at the atomic scale. Similar to what has happened with macroscopic engineering, powerful and generic computational tools will be needed to engineer complex nanosystems, through modeling and simulation. As a result, a major challenge is to develop efficient simulation methods and algorithms.
NANO-D, the INRIA research group I started in January 2008 in Grenoble, France, aims at developing
efficient computational methods for modeling and simulating complex nanosystems, both natural and artificial. In particular, NANO-D develops SAMSON, a software application which gathers all algorithms designed by the group and its collaborators (SAMSON: Software for Adaptive Modeling and Simulation Of Nanosystems).
In this project, I propose to develop a unified theory, and associated algorithms, for adaptive particle simulation. The proposed theory will avoid problems that plague current popular multi-scale or hybrid simulation approaches by simulating a single potential throughout the system, while allowing users to finely trade precision for computational speed.
I believe the full development of the adaptive particle simulation theory will have an important impact on current modeling and simulation practices, and will enable practical design of complex nanosystems on desktop computers, which should significantly boost the emergence of generic nano-engineering."

Summary "The proposed research program has three main objectives. The first and second objectives are to seek extreme precisions in optical atomic spectroscopy and optical clocks, and to use this quest as a mean of exploration in atomic physics. The third objective is to explore new possibilities that stem from extreme precision. These goals will be pursued via three complementary activities: #1: Search for extreme precisions with an Hg optical lattice clock. #2: Explore and exploit the rich Hg system, which is essentially unexplored in the cold and ultra-cold regime. #3: Identify new applications of clocks with extreme precision to Earth science. Clocks can measure directly the gravitational potential via Einstein’s gravitational redshift, leading to the idea of “clock-based geodesy”.
The 2 first activities are experimental and build on an existing setup, where we demonstrated the feasibility of an Hg optical lattice clock. Hg is chosen for its potential to surpass competing systems. We will investigate the unexplored physics of the Hg clock. This includes interactions between Hg atoms, lattice-induced light shifts, and sensitivity to external fields which are specific to the atomic species. Beyond, we will explore the fundamental limits of the optical lattice scheme. We will exploit other remarkable features of Hg associated to the high atomic number and the diversity of stable isotopes. These features enable tests of fundamental physical laws, ultra-precise measurements of isotope shifts, measurement of collisional properties toward evaporative cooling and quantum gases of Hg, investigation of forbidden transitions promising for measuring the nuclear anapole moment of Hg.
The third activity is theoretical and is aimed at initiating collaborations with experts in modelling Earth gravity. With this expertise, we will identify the most promising and realistic approaches for clocks and emerging remote comparison methods to contribute to geodesy, hydrology, oceanography, etc."

Project AMPA Receptor Dynamic Organization and Synaptic transmission in health and disease

Host Institution (HI) CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE CNRS
Call Details Advanced Grant (AdG), LS5, ERC-2013-ADG
Summary AMPA glutamate receptors (AMPAR) play key roles in information processing by the brain as they mediate nearly all fast excitatory synaptic transmission. Their spatio-temporal organization in the post synapse with respect to presynaptic glutamate release sites is a key determinant in synaptic transmission. The activity-dependent regulation of AMPAR organization is at the heart of synaptic plasticity processes underlying learning and memory. Dysfunction of synaptic transmission - hence AMPAR organization - is likely at the origin of a number of brain diseases.
Building on discoveries made during my past ERC grant, our new ground-breaking objective is to uncover the mechanisms that link synaptic transmission with the dynamic organization of AMPAR and associated proteins. For this aim, we have assembled a team of neurobiologists, computer scientists and chemists with a track record of collaboration. We will combine physiology, cellular and molecular neurobiology with development of novel quantitative imaging and biomolecular tools to probe the molecular dynamics that regulate synaptic transmission.
Live high content 3D SuperResolution Light Imaging (SRLI) combined with electron microscopy will allow unprecedented visualization of AMPAR organization in synapses at the scale of individual subunits up to the level of intact tissue. Simultaneous SRLI and electrophysiology will elucidate the intricate relations between dynamic AMPAR organization, trafficking and synaptic transmission. Novel peptide- and small protein-based probes used as protein-protein interaction reporters and modulators will be developed to image and directly interfere with synapse organization.
We will identify new processes that are fundamental to activity dependent modifications of synaptic transmission. We will apply the above findings to understand the causes of early cognitive deficits in models of neurodegenerative disorders and open new avenues of research for innovative therapies.

Summary Fundamental interactions in nature are well described by quantum gauge fields in 4 space-time dimensions (4d). When the strength of gauge interaction is weak the Feynman perturbation techniques are very efficient for the description of most of the experimentally observable consequences of the Standard model and for the study of high energy processes in QCD.
But in the intermediate and strong coupling regime, such as the relatively small energies in QCD, the perturbation theory fails leaving us with no reliable analytic methods (except the Monte-Carlo simulation). The project aims at working out new analytic and computational methods for strongly coupled gauge theories in 4d. We will employ for that two important discoveries: 1) the gauge-string duality (AdS/CFT correspondence) relating certain strongly coupled gauge Conformal Field
Theories to the weakly coupled string theories on Anty-deSitter space; 2) the solvability, or integrability of maximally supersymmetric (N=4) 4d super Yang-Mills (SYM) theory in multicolor limit. Integrability made possible pioneering exact numerical and analytic results in the N=4 multicolor SYM at any coupling, effectively summing up all 4d Feynman diagrams. Recently, we conjectured a system of functional equations - the AdS/CFT Y-system – for the exact spectrum of anomalous dimensions of all local operators in N=4 SYM. The conjecture has passed all available checks. My project is aimed at the understanding of origins of this, still mysterious integrability. Deriving the AdS/CFT Y-system from the first principles on both sides of gauge-string duality should provide a long-awaited proof of the AdS/CFT correspondence itself. I plan to use the Y-system to study the systematic weak and strong coupling expansions and the so called BFKL limit, as well as for calculation of multi-point correlation functions of N=4 SYM. We hope on new insights into the strong coupling dynamics of less supersymmetric gauge theories and of QCD.

Call Details Starting Grant (StG), PE10, ERC-2013-StG
Summary The rise of atmospheric O2 ~2,500 million years ago is one of the most profound transitions in Earth's history. Yet, despite its central role in shaping Earth's surface environment, the cause for the rise of O2 remains poorly understood. Tight coupling between the O2 cycle and the biogeochemical cycles of redox-active elements, such as C, Fe and S, implies radical changes in these cycles before, during and after the rise of O2. These changes, too, are incompletely understood, but have left valuable information encoded in the geological record. This information has been qualitatively interpreted, leaving many aspects of the rise of O2, including its causes and constraints on ocean chemistry before and after it, topics of ongoing research and debate. Here, I outline a research program to address this fundamental question in geochemical Earth systems evolution. The inherently interdisciplinary program uniquely integrates laboratory experiments, numerical models, geological observations, and geochemical analyses. Laboratory experiments and geological observations will constrain unknown parameters of the early biogeochemical cycles, and, in combination with field studies, will validate and refine the use of paleoenvironmental proxies. The insight gained will be used to develop detailed models of the coupled biogeochemical cycles, which will themselves be used to quantitatively understand the events surrounding the rise of O2, and to illuminate the dynamics of elemental cycles in the early oceans.
This program is expected to yield novel, quantitative insight into these important events in Earth history and to have a major impact on our understanding of early ocean chemistry and the rise of O2. An ERC Starting Grant will enable me to use the excellent experimental and computational facilities at my disposal, to access the outstanding human resource at the Weizmann Institute of Science, and to address one of the major open questions in modern geochemistry.

Summary "This proposal aims at strengthening the connections between more fundamentally oriented areas of mathematics like algebra, geometry, analysis, and topology, and the more applied oriented and more recently emerging disciplines of discrete mathematics, optimization, and algorithmics.
The overall goal of the project is to obtain, with methods from fundamental mathematics, new effective tools to unravel the complexity of structures like graphs, networks, codes, knots, polynomials, and tensors, and to get a grip on such complex structures by new efficient characterizations, sharper bounds, and faster algorithms.
In the last few years, there have been several new developments where methods from representation theory, invariant theory, algebraic geometry, measure theory, functional analysis, and topology found new applications in discrete mathematics and optimization, both theoretically and algorithmically. Among the typical application areas are networks, coding, routing, timetabling, statistical and quantum physics, and computer science.
The project focuses in particular on:
A. Understanding partition functions with invariant theory and algebraic geometry
B. Graph limits, regularity, Hilbert spaces, and low rank approximation of polynomials
C. Reducing complexity in optimization by exploiting symmetry with representation theory
D. Reducing complexity in discrete optimization by homotopy and cohomology
These research modules are interconnected by themes like symmetry, regularity, and complexity, and by common methods from algebra, analysis, geometry, and topology."

Summary "In our largely unchanging radio Universe, a highly dynamic component was recently discovered: flashes of bright radio emission that last only milliseconds but appear all over the sky. Some of these radio bursts can be traced to intermittently pulsating neutron stars. Other bursts however, apparently originate far outside our Galaxy. Due to great observational challenges, the evolution of the neutron stars is not understood, while more importantly, the nature of the extragalactic bursts remains an outright mystery.
My overall aim is to understand the physics that drives both kinds of brief and luminous bursts.
My primary goal is to identify the highly compact astrophysical explosions powering the extragalactic bursts. My previous surveys are the state of the art in fast-transient detection; I will now increase by a factor of 10 this exploration volume. In real-time I will provide arcsec positions, 10,000-fold more accurate than currently possible, to localize such extragalactic bursts for the first time and understand their origin.
My secondary goal is to unravel the unexplained evolution of intermittently pulsating neutron stars (building on e.g., my recent papers in Science, 2013), by doubling their number and modeling their population.
To achieve these goals, I will carry out a highly innovative survey: the Apertif-LOFAR Exploration of the Radio Transient Sky. ALERT is over an order of magnitude more sensitive than all current state-of-the art fast-transient surveys.
Through its novel, extremely wide field-of-view, Westerbork/Apertif will detect many tens of extragalactic bursts. Through real-time triggers to LOFAR I will next provide the precise localisation that is essential for radio, optical and high-energy follow-up to, for the first time, shed light on the physics and objects driving these bursts – evaporating primordial black holes; explosions in host galaxies; or, the unknown?"

our project is the development of new algorithms and computer software
capable of autonomously exploring evolving data collections, selecting

issues, it is expected to result in significant advances in
high-impact applications that range from visual mining of the Web and
automated annotation and organization of family photo and video albums
to large-scale information retrieval in television archives.

Summary The goal of this PoC proposal is to boost the creation of a start-up (AllYours) targeting both Internet users as well as small to medium companies (SME) offering full-fledged personalization in notification systems. The Web is now all about users; they are the greediest bandwidth consumers, the ultimate deciders of which applications are actually adopted and also the most prolific content generators. While social networks have taken off at an unexpected scale and speed, Web navigation has radically changed to the point that notification is taking over search: many users now navigate through the links they discover rather than explicit search operations. Yet, users get quickly overwhelmed with the huge amount of information in a click range. For such notification systems to be truly useful, they should be personalized depending on the user activity, operations, posts, interests. Yet, personalization poses several issues such as scalability (it is expensive to store a large amount of information per user) and privacy (users are more and more reluctant to give away their preferences to large companies). At the same time, SMEs are struggling to provide fully personalized services given the expertise and amount of resources such algorithms require.
AllYours is an implicit instant item recommender providing personalization in the notification process without requiring explicit subscriptions to feeds or interests. They only let the system know whether they like the items received or not (eg like/dislike button). In addition, users personal data are stored on their own machine, leaving the space to provide a wide spectrum of privacy guarantees while enabling cross application benefits. Behind the scene, AllYours provides each user with a live social network of participants sharing similar interests, called an implicit social network. AllYours come in two different flavors: (1) Enterprise-AllYours provides a scalable notification and recommendation system targeting all SMEs operating Web content editors & ecommerce sites (2) P2P-AllYours provides a fully decentralized solution without requiring users to ever reveal their private preferences through a clever obfuscation mechanism.

Summary "The first decade of Algorithmic Mechanism Design (AMD) concentrated, very successfully, on the design of truthful mechanisms for the allocation of resources among agents with private preferences.
Truthful mechanisms are ones that incentivize rational users to report their preferences truthfully.
Truthfulness, however, for all its theoretical appeal, suffers from several inherent limitations, mainly its high communication and computation complexities.
It is not surprising, therefore, that practical applications forego truthfulness and use simpler mechanisms instead.
Simplicity in itself, however, is not sufficient, as any meaningful mechanism should also have some notion of fairness; otherwise agents will stop using it over time.
In this project I plan to develop an innovative AMD theoretical framework that will go beyond truthfulness and focus instead on the natural themes of simplicity and fairness, in addition to computational tractability.
One of my primary goals will be the design of simple and fair poly-time mechanisms that perform at near optimal levels with respect to important economic objectives such as social welfare and revenue.
To this end, I will work toward providing precise definitions of simplicity and fairness and quantifying the effects of these restrictions on the performance levels that can be obtained.
A major challenge in the evaluation of non-truthful mechanisms is defining a reasonable behavior model that will enable their evaluation.
The success of this project could have a broad impact on Europe and beyond, as it would guide the design of natural mechanisms for markets of tens of billions of dollars in revenue, such as online advertising, or sales of wireless frequencies.
The timing of this project is ideal, as the AMD field is now sufficiently mature to lead to a breakthrough and at the same time young enough to be receptive to new approaches and themes."

Project Genetics of mosquito resistance to pathogens
Researcher (PI) Kenneth Du Souchet Vernick
Host Institution (HI) INSTITUT PASTEUR
Call Details Advanced Grant (AdG), LS2, ERC-2012-ADG_20120314
Summary Malaria parasite infection in humans has been called “the strongest known force for evolutionary selection in the recent history of the human genome”, and I hypothesize that a similar statement may apply to the mosquito vector, which is the definitive host of the malaria parasite. We previously discovered efficient malaria-resistance mechanisms in natural populations of the African malaria vector, Anopheles gambiae. Aim 1 of the proposed project will implement a novel genetic mapping design to systematically survey the mosquito population for common and rare genetic variants of strong effect against the human malaria parasite, Plasmodium falciparum. A product of the mapping design will be living mosquito families carrying the resistance loci. Aim 2 will use the segregating families to functionally dissect the underlying molecular mechanisms controlled by the loci, including determination of the pathogen specificity spectra of the host-defense traits. Aim 3 targets arbovirus transmission, where Anopheles mosquitoes transmit human malaria but not arboviruses such as Dengue and Chikungunya, even though the two mosquitoes bite the same people and are exposed to the same pathogens, often in malaria-arbovirus co-infections. We will use deep-sequencing to detect processing of the arbovirus dsRNA intermediates of replication produced by the RNAi pathway of the mosquitoes. The results will reveal important new information about differences in the efficiency and quality of the RNAi response between mosquitoes, which is likely to underlie at least part of the host specificity of arbovirus transmission. The 3 Aims will make significant contributions to understanding malaria and arbovirus transmission, major global public health problems, will aid the development of a next generation of vector surveillance and control tools, and will produce a definitive description of the major genetic factors influencing host-pathogen interactions in mosquito immunity.

Project acronym APARTHEID-STOPS
Project Apartheid -- The Global Itinerary: South African Cultural Formations in Transnational Circulation, 1948-1990
Researcher (PI) Louise Bethlehem
Host Institution (HI) THE HEBREW UNIVERSITY OF JERUSALEM
Call Details Consolidator Grant (CoG), SH5, ERC-2013-CoG
Summary This proposal proceeds from an anomaly. Apartheid routinely breached the separation that it names. Whereas the South African regime was deeply isolationist in international terms, new research links it to the Cold War and decolonization. Yet this trend does not consider sufficiently that the global contest over the meaning of apartheid and resistance to it occurs on the terrain of culture. My project argues that studying the global circulation of South African cultural formations in the apartheid era provides novel historiographic leverage over Western liberalism during the Cold War. It recasts apartheid as an apparatus of transnational cultural production, turning existing historiography inside out. This study seeks:
• To provide the first systematic account of the deterritorialization of “apartheid”—as political signifier and as apparatus generating circuits of transnational cultural production.
• To analyze these itinerant cultural formations across media and national borders, articulating new intersections.
• To map the itineraries of major South African exiles, where exile is taken to be a system of interlinked circuits of affiliation and cultural production.
• To revise the historiography of states other than South Africa through the lens of deterritorialized apartheid-era formations at their respective destinations.
• To show how apartheid reveals contradictions within Western liberalism during the Cold War, with special reference to racial inequality.
Methodologically, I introduce the model of thick convergence to analyze three periods:
1. Kliptown & Bandung: Novel possibilities, 1948-1960.
2. Sharpeville & Memphis: Drumming up resistance, 1960-1976.
3. From Soweto to Berlin: Spectacle at the barricades, 1976-1990.
Each explores a cultural dominant in the form of texts, soundscapes or photographs. My work stands at the frontier of transnational research, furnishing powerful new insights into why South Africa matters on the stage of global history.

Project Anionic PhosPhoLipids in plant receptor kinase signaling
Researcher (PI) Yvon Jaillais
Host Institution (HI) CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE CNRS
Call Details Starting Grant (StG), LS3, ERC-2013-StG
Summary "In plants, receptor kinases form the largest family of plasma membrane (PM) receptors and they are involved in virtually all aspects of the plant life, including development, immunity and reproduction. In animals, key molecules that orchestrate the recruitment of signaling proteins to membranes are anionic phospholipids (e.g. phosphatidylinositol phosphate or PIPs). Besides, recent reports in animal and yeast cells suggest the existence of PM nanodomains that are independent of cholesterol and lipid phase and rely on anionic phospholipids as well as electrostatic protein/lipid interactions. Strikingly, we know very little on the role of anionic phospholipids in plant signaling. However, our preliminary data suggest that BKI1, an inhibitory protein of the steroid receptor kinase BRI1, interacts with various PIPs in vitro and is likely targeted to the PM by electrostatic interactions with these anionic lipids. These results open the possibility that BRI1, but also other receptor kinases, might be regulated by anionic phospholipids in plants. Here, we propose to analyze the function of anionic phospholipids in BRI1 signaling, using the root epidermis as a model system. First, we will ask what are the lipids that control membrane surface charge in this tissue and recruit BR-signaling component to the PM. Second, we will probe the presence of PIP-enriched nanodomains at the plant PM using super-resolution microscopy techniques and investigate the roles of these domains in BRI1 signaling. Finally, we will analyze the function of the BKI1-related plant-specific family of anionic phospholipid effectors in plant development. In summary, using a transversal approach ranging from in vitro studies to in vivo validation and whole organism physiology, this work will unravel the interplay between anionic phospholipids and receptor signaling in plants."

Researcher (PI) Albertus Dominicus Marcellinus Erasmus OSTERHAUS
Host Institution (HI) ERASMUS UNIVERSITAIR MEDISCH CENTRUM ROTTERDAM
Call Details Proof of Concept (PoC), PC1, ERC-2012-PoC
Summary ARCAS will investigate the commercial potential and commercialization strategy of a platform of continuously updated repository of pandemic influenza vaccine candidates that was developed under the ERC project FLUPLAN. This platform is based on a novel vector technology using recombinant modified vaccinia virus Ankara (MVA) to develop pandemic influenza vaccines. There are two major advantages of the platform in comparison to current pandemic influenza vaccine platforms using adjuvanted-inactivated and live-attenuated influenza vaccines: i) the high immunogenicity induced in the absence of adjuvants, even at very low dosages, and ii) higher and faster vaccine production capacity. This addresses today’s key unmet needs of pandemic influenza vaccines: strong and broad immunogenicity as well as virtually unlimited production capacity for large scale vaccination campaigns needed in the face of an emerging influenza pandemic. While FLUPLAN addresses the technical development of the platform, including one of the promising candidate vaccines (MVA-based influenza A/H5N1 vaccine), ARCAS will focus on the commercial potential and the commercialization strategy for the platform. This will be achieved by conducting an extensive market study to determine the potential for the novel vaccine repository platform, by analyzing the IP position to build a solid IP portfolio, and by conducting a technical evaluation on the potential of the platform. This will provide the basis to determine the commercial potential and subsequently the most viable commercialization strategy for the platform, to be detailed in a strategic business plan. Furthermore, as part of the strategic business plan, we aim to develop a sound factsheet that will allow potential commercial partners to invest in the technology, addressing the current influenza market needs, given the competitive advantage offered by the platform.

Project The roles of innate lymphoid cells and rhinovirus in asthma exacerbations
Researcher (PI) Hergen Spits
Host Institution (HI) ACADEMISCH MEDISCH CENTRUM BIJ DE UNIVERSITEIT VAN AMSTERDAM
Call Details Advanced Grant (AdG), LS6, ERC-2013-ADG
Summary Asthma exacerbations represent a high unmet medical need in particular in young children. Human Rhinoviruses (HRV) are the main triggers of these exacerbations. Till now Th2 cells were considered the main initiating effector cell type in asthma in general and asthma exacerbations in particular. However, exaggerated Th2 cell activities alone do not explain all aspects of asthma and exacerbations. Building on our recent discovery of type 2 human innate lymphoid cells (ILC2) capable of promptly producing high amounts of IL-5, IL-9 and IL-13 upon activation and on mouse data pointing to an essential role of these cells in asthma and asthma exacerbations, ILC2 may be the main initiating cells in asthma exacerbations in humans. Thus we hypothesize that HRV directly or indirectly stimulate ILC2s to produce cytokines driving the effector functions leading to the end organ effects that characterize this debilitating disease. Targeting ILC2 and HRV in parallel will provide a highly attractive therapeutic option for the treatment of asthma exacerbations. In depth study of the mechanisms of ILC2 differentiation and function will lead to the design effective drugs targeting these cells; thus the first two objectives of this project are: 1) To unravel the lineage relationship of ILC populations and to decipher the signal transduction pathways that regulate the function of ILCs, 2) to test the functions of lung-residing human ILCs and the effects of compounds that affect these functions in mice which harbour a human immune system and human lung epithelium under homeostatic conditions and after infections with respiratory viruses. The third objective of this project is developing reagents that target HRV; to this end we will develop broadly reacting highly neutralizing human monoclonal antibodies that can be used for prophylaxis and therapy of patients at high risk for developing severe asthma exacerbations.

Project Reconstructing Earth’s mantle convection
Researcher (PI) Nicolas Coltice
Host Institution (HI) UNIVERSITE LYON 1 CLAUDE BERNARD
Call Details Consolidator Grant (CoG), PE10, ERC-2013-CoG
Summary Knowledge of the state of the Earth mantle and its temporal evolution is fundamental to a variety of disciplines in Earth Sciences, from the internal dynamics to its many expressions in the geological record (postglacial rebound, sea level change, ore deposit, tectonics or geomagnetic reversals). Mantle convection theory is the centerpiece to unravel the present and past state of the mantle. For the past 40 years considerable efforts have been made to improve the quality of numerical models of mantle convection. However, they are still sparsely used to estimate the convective history of the solid Earth, in comparison to ocean or atmospheric models for weather and climate prediction. The main shortcoming is their inability to successfully produce Earth-like seafloor spreading and continental drift self-consistently. Recent convection models have begun to successfully predict these processes (Coltice et al., Science 336, 335-33, 2012). Such breakthrough opens the opportunity to combine high-level data assimilation methodologies and convection models together with advanced tectonic datasets to retrieve Earth's mantle history. The scope of this project is to produce a new generation of tectonic and convection reconstructions, which are key to improve our understanding and knowledge of the evolution of the solid Earth. The development of sustainable high performance numerical models will set new standards for geodynamic data assimilation. The outcome of the AUGURY project will be a new generation of models crucial to a wide variety of disciplines.

Host Institution (HI) UNIVERSITEIT VAN AMSTERDAM
Call Details Advanced Grant (AdG), SH2, ERC-2012-ADG_20120411
Summary The overarching research question of this project is: how is authoritarian rule affected by and responding to globalisation of (a) information and communication, (b) association, and (c) people movement? The wholly unpredicted series of revolts that recently spread across the Arab world suggests that the nature and sustainability of contemporary authoritarian rule are not well-understood. Openness to global ICT and media, international NGOs, and inflow and outflow of people have thrown up new challenges for authoritarian rulers in terms of how to control citizens. This project investigates changes in both the nature and the sustainability of authoritarian rule in relation to the erosion of decision-making autonomy at the state level posited by globalisation theorists.
In four sub-projects, this project will investigate:
1. Whether, how and to what extent globalisation of information and communication, association, and people movement affect authoritarian persistence (longitudinal quantitative study, 1970-2011)
2. How, i.e. with what policy mechanisms, authoritarian states respond to globalisation of information and communication, association, and people movement (qualitative multi-sited studies relating to Belarus, China, Iran and Zimbabwe)
3. How to understand the phenomenon of subnational authoritarianism in its engagement with the democratic state and the wider world in relation to information and communication, association, and people movement (mixed method subnational studies of states within India and Mexico)
4. What authoritarianism is in a global age: reconsidering authoritarianism’s defining characteristics of low accountability and high coercion, and whether these still relate exclusively to statehood (theory study)
The project will transcend the theoretical and empirical separation between globalisation studies (which have neglected authoritarian contexts) and authoritarianism studies(which have taken relatively little notice of effects of globalisation)

Project Systematic analysis of the molecular mechanisms underlying axon growth during development and following injury
Researcher (PI) Oren Schuldiner
Host Institution (HI) WEIZMANN INSTITUTE OF SCIENCE
Call Details Consolidator Grant (CoG), LS5, ERC-2013-CoG
Summary Axon growth potential declines during development, contributing to the lack of effective regeneration in the adult central nervous system. What determines the intrinsic growth potential of neurites, and how such growth is regulated during development, disease and following injury is a fundamental question in neuroscience. Although multiple lines of evidence indicate that intrinsic growth capability is genetically encoded, its nature remains poorly defined. Neuronal remodeling of the Drosophila mushroom body offers a unique opportunity to study the mechanisms of various types of axon degeneration and growth. We have recently demonstrated that regrowth of axons following developmental pruning is not only distinct from initial outgrowth but also shares molecular similarities with regeneration following injury. In this proposal we combine state of the art tools from genomics, functional genetics and microscopy to perform a comprehensive study of the mechanisms underlying axon growth during development and following injury. First, we will combine genetic, biochemical and genomic studies to gain a mechanistic understanding of the developmental regrowth program. Next, we will perform extensive transcriptomic analyses and comparisons aimed at defining the genetic programs involved in initial axon growth, developmental regrowth, and regeneration following injury. Finally, we will harness the genetic power of Drosophila to perform a comprehensive functional analysis of genes and pathways, those previously known and new ones that we will discover, in various neurite growth paradigms. Importantly, these functional assays will be performed in the same organism, allowing us to use identical genetic mutations across our analyses. To this end, our identification of a new genetic program regulating developmental axon regrowth, together with emerging tools in genomics, places us in a unique position to gain a broad understanding of axon growth during development and following injury.

Summary In bacteria, the though external cell wall and the intracellular actin-like (MreB) cytoskeleton are major determinants of cell shape. The biosynthetic pathways and chemical composition of the cell wall, a three dimensional polymer network that is one of the most prominent targets for antibiotics, are well understood. However, despite decades of study, little is known about the complex cell wall ultrastructure and the molecular mechanisms that control cell wall morphogenesis in time and space. In rod-shaped bacteria, MreB homologues assemble into dynamic structures thought to control shape by serving as organizers for the movement and assembly of macromolecular machineries that effect sidewall elongation. However, the mechanistic details used by the MreB cytoskeleton to fulfil this role remain to be elucidated. Furthermore, development of high-resolution microscopy techniques has led to new breakthroughs this year, published by our lab and others, which are shaking the model developed over the last decade and re-questioning the MreB “actin cytoskeleton” designation.
The aim of this project is to combine powerful genetic, biochemical, genomic and systems biology approaches available in the model bacterium Bacillus subtilis with modern high-resolution light microscopic techniques to study the dynamics and mechanistic details of the MreB cytoskeleton and of CW assembly. Parameters measured by the different approaches will be combined to quantitatively describe the features of bacterial cell morphogenesis.

Project Recognition of bacteria by NK cells
Researcher (PI) Ofer Mandelboim

Call Details Advanced Grant (AdG), LS6, ERC-2012-ADG_20120314
Summary NK cells that are well known by their ability to recognize and eliminate virus infected and tumor cells were also implicated in the defence against bacteria. However, the recognition of bacteria by NK cells is only poorly understood. we do not know how bacteria are recognized and the functional consequences of such recognition are also weakly understood. In the current proposal we aimed at determining the “NK cell receptor-bacterial interactome”. We will examine the hypothesis that NK inhibitory and activating receptors are directly involved in bacterial recognition. This ground breaking hypothesis is based on our preliminary results in which we show that several NK cell receptors directly recognize various bacterial strains as well as on a few other publications. We will generate various mice knockouts for NCR1 (a major NK killer receptor) and determine their microbiota to understand the physiological function of NCR1 and whether certain bacterial strains affects its activity. We will use different human and mouse NK killer and inhibitory receptors fused to IgG1 to pull-down bacteria from saliva and fecal samples and then use 16S rRNA analysis and next generation sequencing to determine the nature of the bacteria species isolated. We will identify the bacterial ligands that are recognized by the relevant NK cell receptors, using bacterial random transposon insertion mutagenesis approach. We will end this research with functional assays. In the wake of the emerging threat of bacterial drug resistance and the involvement of bacteria in the pathogenesis of many different chronic diseases and in shaping the immune response, the completion of this study will open a new field of research; the direct recognition of bacteria by NK cell receptors.

Summary Bacteria in nature exhibit remarkable capacity to sense their surroundings and rapidly adapt to diverse conditions by gaining new beneficial traits. This extraordinary feature facilitates their survival when facing extreme environments. Utilizing Bacillus subtilis as our primary model organism, we propose to study two facets of this vital bacterial attribute: communication via extracellular nanotubes, and persistence as resilient spores while maintaining the potential to revive. Exploring these fascinating aspects of bacterial physiology is likely to change our view as to how bacteria sense, respond, endure and communicate with their extracellular environment.
We have recently discovered a previously uncharacterized mode of bacterial communication, mediated by tubular extensions (nanotubes) that bridge neighboring cells, providing a route for exchange of intracellular molecules. Nanotube-mediated molecular sharing may represent a key form of bacterial communication in nature, allowing for the emergence of new phenotypes and increasing survival in fluctuating environments. Here we propose to develop strategies for observing nanotube formation and molecular exchange in living bacterial cells, and to characterize the molecular composition of nanotubes. We will explore the premise that nanotubes serve as a strategy to expand the cell surface, and will determine whether nanotubes provide a conduit for phage infection and spreading. Furthermore, the formation and functionality of interspecies nanotubes will be explored. An additional mode employed by bacteria to achieve extreme robustness is the ability to reside as long lasting spores. Previously held views considered the spore to be dormant and metabolically inert. However, we have recently shown that at least one week following spore formation, during an adaptive period, the spore senses and responds to environmental cues and undergoes corresponding molecular changes, influencing subsequent emergence from quiescence.

Researcher (PI) Yuval Ebenstein
Host Institution (HI) TEL AVIV UNIVERSITY
Call Details Starting Grant (StG), PE4, ERC-2013-StG
Summary Next generation sequencing (NGS) is revolutionizing all fields of biological research but it fails to extract the full range of information associated with genetic material and is lacking in its ability to resolve variations between genomes. The high degree of genome variation exhibited both on the population level as well as between genetically “identical” cells (even in the same organ) makes genetic and epigenetic analysis on the single cell and single genome level a necessity.
Chromosomes may be conceptually represented as a linear one-dimensional barcode. However, in contrast to a traditional binary barcode approach that considers only two possible bits of information (1 & 0), I will use colour and molecular structure to expand the variety of information represented in the barcode. Like colourful beads threaded on a string, where each bead represents a distinct type of observable, I will label each type of genomic information with a different chemical moiety thus expanding the repertoire of information that can be simultaneously measured. A major effort in this proposal is invested in the development of unique chemistries to enable this labelling.
I specifically address three types of genomic variation: Variations in genomic layout (including DNA repeats, structural and copy number variations), variations in the patterns of chemical DNA modifications (such as methylation of cytosine bases) and variations in the chromatin composition (including nucleosome and transcription factor distributions). I will use physical extension of long DNA molecules on surfaces and in nanofluidic channels to reveal this information visually in the form of a linear, fluorescent “barcode” that is read-out by advanced imaging techniques. Similarly, DNA molecules will be threaded through a nanopore where the sequential position of “bulky” molecular groups attached to the DNA may be inferred from temporal modulation of an ionic current measured across the pore.

Summary Myocardial infarction is responsible for nearly 40% of the mortality in the western world and is mainly triggered by rupture of vulnerable atherosclerotic plaques in the coronary arteries. Biomechanical parameters play a major role in the generation and rupture of vulnerable plaques. I was the first to show the relationship between shear stress – one of the biomechanical parameters - and plaque formation in human coronary arteries in vivo. This accomplishment was achieved by the development of a new 3D reconstruction technique for (human) coronary arteries in vivo. This reconstruction technique allowed assessment of shear stress by computational fluid dynamics and thereby opened new avenues for serial studies on the role of biomechanical parameters in cardiovascular disease. However, these reconstructions lack information on the vessel wall composition, which is essential for stress computations in the vessel wall. Recent developments in intravascular image technologies allow visualization of one or more of the different plaque components. Therefore, advances in image fusion are required to merge the different plaque components into one single 3D vulnerable plaque reconstruction. I will go beyond the state-of-the art in image based modeling by developing novel technology to 3D reconstruct coronary lumen and vessel wall, including plaque composition and assess biomechanical tissue properties allowing for full biomechanical characterization (shear stress and wall stress) of the coronary plaque. The developed technology will be applied to study 1) vulnerable plaque progression, destabilization and rupture, to improve identification of risk on myocardial infarction and 2) predicting treatment outcome of stent implantation by simulating stent deployment, thereby opening a whole new direction in cardiovascular research.

Call Details Advanced Grant (AdG), LS3, ERC-2012-ADG_20120314
Summary Tissue morphogenesis is a complex process that emerges from spatially controlled patterns of cell shape changes. Dedicated genetic programmes regulate cell behaviours, exemplified in animals by the specification of apical constriction in invaginating epithelial tissues, or the orientation of cell intercalation during tissue extension. This genetic control is constrained by physical properties of cells that dictate how they can modify their shape. A major challenge is to understand how biochemical pathways control subcellular mechanics in epithelia, such as how forces are produced by interactions between actin filaments and myosin motors, and how these forces are transmitted at cell junctions. The major objective of our project is to investigate the fundamental principles of epithelial mechanics and to understand how intercellular signals and mechanical coupling between cells coordinate individual behaviours at the tissue level.
We will study early Drosophila embryogenesis and combine quantitative cell biological studies of cell dynamics, biophysical characterization of cell mechanics and genetic control of cell signalling to answer the following questions: i) how are forces generated, in particular what underlies deformation and stabilization of cell shape by actomyosin networks, and pulsatile contractility; ii) how are forces transmitted at junctions, what are the feedback interactions between tension generation and transmission; iii) how are individual cell mechanics orchestrated at the tissue level to yield collective tissue morphogenesis?
We expect to encapsulate the information-based, cell biological and physical descriptions of morphogenesis in a single, coherent framework. The project should impact more broadly on morphogenesis in other organisms and shed light on the mechanisms underlying robustness and plasticity in epithelia.

Summary The aetiology of many musculoskeletal (MS) diseases is related to biomechanical factors. However, the tools to assess the biomechanical condition of patients used by clinicians and researchers are often crude and subjective leading to non-optimal patient analyses and care. In this project innovations related to imaging, sensor technology and biomechanical modelling are utilized to generate versatile, accurate and objective methods to quantify the (pathological) MS condition of the lower extremity of patients in a unique manner. The project will produce advanced diagnostic, pre-planning and outcome tools which allow clinicians and researchers for detailed biomechanical analysis about abnormal tissue deformations, pathological loading of the joints, abnormal stresses in the hard and soft tissues, and aberrant joint kinematics.
The key objectives of this proposal are:
1) Develop and validate image-based 3-D volumetric elastographic diagnostic methods that can quantify normal and pathological conditions under dynamic loading and which can be linked to biomechanical modelling tools.
2) Create an ultrasound (US)-based system to assess internal joint kinematics which can be used as a diagnostic tool for clinicians and researchers and is a validation tool for biomechanical modelling.
3) Generate and validate an ambulant functional (force and kinematic) diagnostic system which is easy to use and which can be used to provide input data for biomechanical models.
4) Create and validate a new modelling approach that integrates muscle-models with finite element models at a highly personalized level.
5) Generate biomechanical models which have personalized mechanical properties of the hard and soft tissues.
6) Demonstrate the applicability of the personalized diagnostic and pre-planning platform by application to healthy individuals and patient subjects.
Support from the ERC will open new research fields related to biomechanical patient assessment and modeling of MS pathologies.

Summary "In the course of biomineralization, organisms produce a large variety of functional biogenic crystals that exhibit fascinating mechanical, optical, magnetic and other characteristics. More specifically, when living organisms grow crystals they can effectively control polymorph selection as well as the crystal morphology, shape, and even atomic structure. Materials existing in nature have extraordinary and specific functions, yet the materials employed in nature are quite different from those engineers would select.
I propose to emulate specific strategies used by organisms in forming structural biogenic crystals, and to apply these strategies biomimetically so as to form new structural materials with new properties and characteristics. This bio-inspired approach will involve the adoption of three specific biological strategies. We believe that this procedure will open up new ways to control the structure and properties of smart materials.
The three bio-inspired strategies that we will utilize are:
(i) to control the short-range order of amorphous materials, making it possible to predetermine the polymorph obtained when they transform from the amorphous to the succeeding crystalline phase;
(ii) to control the morphology of single crystals of various functional materials so that they can have intricate and curved surfaces and yet maintain their single-crystal nature;
(iii) to entrap organic molecules into single crystals of functional materials so as to tailor and manipulate their electronic structure.
The proposed research has significant potential for opening up new routes for the formation of novel functional materials. Specifically, it will make it possible for us
(1) to produce single, intricately shaped crystals without the need to etch, drill or polish;
(2) to control the short-range order of amorphous materials and hence the polymorph of the successive crystalline phase;
(3) to tune the band gap of semiconductors via incorporation of tailored bio-molecules."

Summary "The ability to apply forces to single molecules and bio-polymers has fundamentally changed the way we can interact with and understand biological systems. Yet, for many cellular mechanisms, it is rather the torque that is the relevant physical parameter. Excitingly, novel single-molecule techniques that utilize this parameter are now poised to contribute to novel discoveries. Here, I will study the angular dynamical behavior and response to external torque of biological systems at the molecular and cellular levels using the new optical torque wrench that I recently developed.
In a first research line, I will unravel the angular dynamics of the e.coli flagellar motor, a complex and powerful rotary nano-motor that rotates the flagellum in order to propel the bacterium forwards. I will quantitatively study different aspects of torque generation of the motor, aiming to connect evolutionary, dynamical, and structural principles. In a second research line, I will develop an in-vivo manipulation technique based on the transfer of optical torque and force onto novel nano-fabricated particles. This new scanning method will allow me to map physical properties such as the local viscosity inside living cells and the spatial organization and topography of internal membranes, thereby expanding the capabilities of existing techniques towards in-vivo and ultra-low force scanning imaging.
This project is founded on a multidisciplinary approach in which fundamental optics, novel nanoparticle fabrication, and molecular and cellular biology are integrated. It has the potential to answer biophysical questions that have challenged the field for over two decades and to impact fields ranging from single-molecule biophysics to scanning-probe microscopy and nanorheology, provided ERC funding is granted."

Summary "Transcriptional regulation of protein coding genes in eukaryotic cells requires a complex interplay of sequence-specific DNA-binding factors, co-activators, general transcription factors (GTFs), RNA polymerase II and the epigenetic status of target sequences. Nuclear transcription complexes function as large multiprotein assemblies and are often composed of functional modules. The regulated decision-making that exists in cells governing the assembly and the allocation of factors to different transcription complexes to regulate distinct gene expression pathways is not yet understood. To tackle this fundamental question, we will systematically analyse the regulated biogenesis of transcription complexes from their sites of translation in the cytoplasm, through their assembly intermediates and nuclear import, to their site of action in the nucleus. The project will have four main Aims to decipher the biogenesis of transcription complexes:
I) Investigate their co-translation-driven assembly
II) Determine their cytoplasmic intermediates and factors required for their assembly pathways
III) Uncover their nuclear import
IV) Understand at the single molecule level their nuclear assembly, dynamics and action at target genes
To carry out these aims we propose a combination of multidisciplinary and cutting edge approaches, out of which some of them will be high-risk taking, while others will utilize methods routinely run by the group. The project builds on several complementary expertise and knowledge either already existing in the group or that will be implemented during the project. At the end of the proposed project we will obtain novel results extensively describing the different steps of the regulatory mechanisms that control the assembly and the consequent gene regulatory function of transcription complexes. Thus, we anticipate that the results of our research will have a major impact on the field and will lead to a new paradigm for contemporary metazoan transcription."

III) Uncover their nuclear import
IV) Understand at the single molecule level their nuclear assembly, dynamics and action at target genes
To carry out these aims we propose a combination of multidisciplinary and cutting edge approaches, out of which some of them will be high-risk taking, while others will utilize methods routinely run by the group. The project builds on several complementary expertise and knowledge either already existing in the group or that will be implemented during the project. At the end of the proposed project we will obtain novel results extensively describing the different steps of the regulatory mechanisms that control the assembly and the consequent gene regulatory function of transcription complexes. Thus, we anticipate that the results of our research will have a major impact on the field and will lead to a new paradigm for contemporary metazoan transcription."

Summary The dysregulation of signaling pathways that mediate cell proliferation, survival and migration is an underlying cause of many cancers. In particular, dysregulation and over-expression of avb3 integrin, membrane-type-1 matrix metalloproteinase (MT1-MMP; also known as matrix metalloproteinase-14, MMP14) and vascular endothelial growth factor receptor-2 (VEGFR2) correlate with poor prognosis in many human tumors, making these proteins attractive targets for therapeutic intervention. Numerous papers have demonstrated the cross-talk between biological processes mediated by αvβ3 integrins, MT1-MMP, VEGFR2, and their ligands, particularly pathways responsible for angiogenesis. Dual-specific proteins that can target and inhibit the activity of the above multiple receptors therefore have superior potential to single-targeted agents due to differential expression of these disease markers in different patients and the ability of this expression to change over time. Most currently available bispecific protein therapeutics comprise antibodies (Abs) or antibody fragments. The new approach proposed here entails rational and combinatorial methods for engineering multispecificity into small peptides and natural protein ligands to function as non-immunoglobulin alternatives to antibodies. In this innovative approach to creating dual-specific proteins, an additional functionality is introduced into a small peptide or into a natural protein ligand to complement its existing biological properties. We predict that this approach will form a major part of a highly effective strategy for creating ligand-based multispecific receptor inhibitors and molecular tools for protein recognition. We envision that protein variants generated from these efforts will promote the next generation of therapeutics including, but not limited to, molecular imaging agents, targeted drug delivery agents, and selective tissue targeting probes.

Project The formation and evolution of massive black holes
Researcher (PI) Marta Volonteri
Host Institution (HI) CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE CNRS
Call Details Consolidator Grant (CoG), PE9, ERC-2013-CoG
Summary "Massive black holes (MBHs) weighing million solar masses and above inhabit the centers of today's galaxies, weighing about a thousandth of the host bulge mass. MBHs also powered quasars known to exist just a few hundred million years after the Big Bang. Owing to observational breakthroughs and remarkable advancements in theoretical models, we do now that MBHs are out there and evolved with their hosts, but we do not know how they got there nor how, and when, the connection between MBHs and hosts was established.
To have a full view of MBH formation and growth we have to look at the global process where galaxies form, as determined by the large-scale structure, on Mpc scales. On the other hand, the region where MBHs dominate the dynamics of gas and stars, and accretion occurs, is merely pc-scale. To study the formation of MBHs and their fuelling we must bridge from Mpc to pc scale in order to follow how galaxies influence MBHs and how in turn MBHs influence galaxies.
BLACK aims to connect the cosmic context to the nuclear region where MBHs reside, and to study MBH formation, feeding and feedback on their hosts through a multi-scale approach following the thread of MBHs from cosmological, to galactic, to nuclear scales. Analytical work guides and tests numerical simulations, allowing us to probe a wide dynamical range.
Our theoretical work will be crucial for planning and interpreting current and future observations. Today and in the near future facilities at wavelengths spanning from radio to X-ray will widen and deepen our view of the Universe, making this an ideal time for this line of research."

Project Imaging the Event Horizon of Black Holes

Call Details Synergy Grants (SyG), SYG6, ERC-2013-SyG
Summary Gravity is successfully described by Einstein’s theory of general relativity (GR), governing the structure of our entire universe. Yet it remains the least understood of all forces in nature, resisting unification with quantum physics. One of the most fundamental predictions of GR are black holes (BHs). Their defining feature is the event horizon, the surface that light cannot escape and where time and space exchange their nature. However, while there are many convincing BH candidates in the universe, there is no experimental proof for the existence of an event horizon yet. So, does GR really hold in its most extreme limit? Do BHs exist or are alternatives needed? Here we propose to build a Black Hole Camera that for the first time will take an actual picture of a BH and image the shadow of its event horizon. We will do this by providing the equipment and software needed to turn a network of existing mm-wave radio telescopes into a global interferometer. This virtual telescope, when supplemented with the new Atacama Large Millimetre Array (ALMA), has the power to finally resolve the supermassive BH in the centre of our Milky Way – the best-measured BH candidate we know of. In order to compare the image with the theoretical predictions we will need to perform numerical modelling and ray tracing in GR and alternative theories. In addition, we will need to determine accurately the two basic parameters of the BH: its mass and spin. This will become possible by precisely measuring orbits of stars with optical interferometry on ESO’s VLTI. Moreover, our equipment at ALMA will allow for the first detection of pulsars around the BH. Already a single pulsar will independently determine the BH’s mass to one part in a million and its spin to a few per cent. This unique combination will not only produce the first-ever image of a BH, but also turn our Galactic Centre into a fundamental-physics laboratory to measure the fabric of space and time with unprecedented precision.

Project Targeting BMP4 and BMPR1a for imaging of esophageal adenocarcinoma
Researcher (PI) Kausilia Krishnawatie KRISHNADATH
Host Institution (HI) ACADEMISCH MEDISCH CENTRUM BIJ DE UNIVERSITEIT VAN AMSTERDAM
Call Details Proof of Concept (PoC), PC1, ERC-2013-PoC
Summary Within BMP4EAC we aim to investigate the commercial feasibility of our newly discovered and highly specific antibodies against BMP4 and one of its receptors, BMPR1a, for imaging applications in oncology. BMP4 and BMPR1a are highly expressed in esophageal adenocarcinoma (EAC) and other tumors as well as their metastases. The specificity, strong binding capacity, rapid clearance, high tissue penetration level, and flexibility of our antibodies is unprecedented and makes them highly suitable for in vivo imaging applications.
The opportunity: The current methods for evaluation of disease stage consist of diverse modalities, including, CT and PET-CT scans, and ultrasonography. These techniques have major limitations to accurately detect metastasis and are inadequate for monitoring disease response. In the clinical setting we foresee applications of our proprietary technology in the non-invasive diagnosis of tumors and metastases with high expression of BMP4 and/or BMPR1a (e.g. EAC), identification of patients with high chance to respond to BMP4 inhibitors, follow tumor progression during treatment, and facilitated localization of small metastases during surgical treatment. Furthermore, the labeled antibodies can be used to investigate the efficacy of novel therapeutic agents by following tumor progression in animal models in a research setting.
The project and expected outcomes: Within the ERC PoC we will explore the commercial feasibility by in vivo validation experiments as well as by performing essential research for the formulation of a business proposition, strengthening our IP position, and developing a sound business plan. These activities will result in a proposition package that will be used to present the commercial potential to investors and other strategic partners to attract funding after completion of the ERC PoC and potentially even initiate licensing and partnership deals.

Summary Mindfulness-based therapy has become an increasingly popular treatment to reduce stress, increase well-being and prevent relapse in depression. A key component of these therapies includes mindfulness practice that intends to train attention to detect and regulate afflictive cognitive and emotional patterns. Beyond its therapeutic application, the empirical study of mindfulness practice also represents a promising tool to understand practices that intentionally cultivate present-centeredness and openness to experience. Despite its clinical efficacy, little remains known about its means of action. Antithetic to this mode of experiential self-focus are states akin to depression, that are conducive of biased attention toward negativity, biased thoughts and rumination, and dysfunctional self schemas. The proposed research aims at implementing an innovative framework to scientifically investigate the experiential, cognitive, and neural processes underlining mindfulness practice building on the current neurocognitive understanding of the functional and anatomical architecture of cognitive control, and depression. To identify these mechanisms, this project aims to use paradigms from cognitive, and affective neuroscience (MEG, intracortical EEG, fMRI) to measure the training and plasticity of emotion regulation and cognitive control, and their effect on automatic, self-related affective processes. Using a cross-sectional design, this project aims to compare participants with trait differences in experiential self-focus mode. Using a longitudinal design, this project aims to explore mindfulness-practice training’s effect using a standard mindfulness-based intervention and an active control intervention. The PI has pioneered the neuroscientific investigation of mindfulness in the US and aspires to assemble a research team in France and a network of collaborators in Europe to pursue this research, which could lead to important outcomes for neuroscience, and mental health.

Summary The cerebral microvascular system is essential to a large variety of physiological processes in the brain, including blood delivery and blood flow regulation as a function of neuronal activity (neuro-vascular coupling). It plays a major role in the associated mechanisms leading to disease (stroke, neurodegenerative diseases, …). In the last decade, cutting edge technologies, including two-photon scanning laser microscopy (TPSLM) and optical manipulation of blood flow, have produced huge amounts of anatomic and functional experimental data in normal and Alzheimer Disease (AD) mice. These require accurate, highly quantitative, physiologically informed modeling and analysis for any coherent understanding and for translating results between species.
In this context, our first aim is to develop a general methodological framework for physiologically informed microvascular fluid dynamics modeling, understood in a broad meaning, i.e. blood flow, molecule transport and resulting functional imaging signals or signal surrogates.
Our second aim is to validate this methodological framework by direct comparison of in vivo anatomical and functional TPSLM measurements with the simulation results based on the same anatomical data.
The third objective is to exploit these methodologies in order to identify the logic of the structure/function relationships of brain microcirculation and neurovascular coupling, in human health and disease, with a focus on the role of vascular factors in AD.
Specific hypotheses on how vascular changes in AD affect both vascular function and neurovascular coupling can be experimentally tested in animal models of AD. Crucially, similar anatomical (but not functional) data can be acquired in healthy and AD humans. This will enable us to model how AD-induced vascular alterations could affect human patients. Ultimately, it provides us with new avenues for design and/or evaluation of improved diagnosis/preventive/treatment strategies.

Summary My lab's work ranges from basic science, querying brain plasticity and sensory integration, to technological developments, allowing the blind to be more independent and even “see” using sounds and touch similar to bats and dolphins (a.k.a. Sensory Substitution Devices, SSDs), and back to applying these devices in research. We propose that, with proper training, any brain area or network can change the type of sensory input it uses to retrieve behaviorally task-relevant information within a matter of days. If this is true, it can have far reaching implications also for clinical rehabilitation. To achieve this, we are developing several innovative SSDs which encode the most crucial aspects of vision and increase their accessibility the blind, along with targeted, structured training protocols both in virtual environments and in real life. For instance, the “EyeMusic”, encodes colored complex images using pleasant musical scales and instruments, and the “EyeCane”, a palm-size cane, which encodes distance and depth in several directions accurately and efficiently. We provide preliminary but compelling evidence that following such training, SSDs can enable almost blind to recognize daily objects, colors, faces and facial expressions, read street signs, and aiding mobility and navigation. SSDs can also be used in conjunction with (any) invasive approach for visual rehabilitation. We are developing a novel hybrid Visual Rehabilitation Device which combines SSD and bionic eyes. In this set up, the SSDs is used in training the brain to “see” prior to surgery, in providing explanatory signal after surgery and in augmenting the capabilities of the bionic-eyes using information arriving from the same image. We will chart the dynamics of the plastic changes in the brain by performing unprecedented longitudinal Neuroimaging, Electrophysiological and Neurodisruptive approaches while individuals learn to ‘see’ using each of the visual rehabilitation approaches suggested here.

Summary "This project is concerned with problems that involve a very large number of variables, and whose efficient numerical treatment is challenged by the so-called curse of dimensionality, meaning that computational complexity increases exponentially in the variable dimension.
The PI intend to establish in his host institution a scientific leadership on the mathematical understanding and numerical treatment of these problems, and to contribute to the development of this area of research through international collaborations, organization of workshops and research schools, and training of postdocs and PhD students.
High dimensional problems are ubiquitous in an increasing number of areas of scientific computing, among which statistical or active learning theory, parametric and stochastic partial differential equations, parameter optimization in numerical codes. There is a high demand from the industrial world of efficient numerical methods for treating such problems.
The practical success of various numerical algorithms, that have been developed in recent years in these application areas, is often limited to moderate dimensional setting.
In addition, these developments tend to be, as a rule, rather problem specific and not always founded on a solid mathematical analysis.
The central scientific objectives of this project are therefore: (i) to identify fundamental mathematical principles behind overcoming the curse of dimensionality, (ii) to understand how these principles enter in relevant instances of the above applications, and (iii) based on the these principles beyond particular problem classes, to develop broadly applicable numerical strategies that benefit from such mechanisms.
The performances of these strategies should be provably independent of the variable dimension, and in that sense break the curse of dimensionality. They will be tested on both synthetic benchmark tests and real world problems coming from the afore-mentioned applications."

Summary Microfluidic techniques developed since the year 2000 have now matured to provide a unique tool to produce large amounts of microbubbles that are not only finely tuned in size, but that can also be embedded in tiny microfabricated structures.
In the present proposal, we plan to take advantage of these novel microfabrication techniques to develop two innovative acoustic applications. These applications, which were out of reach without current techniques, are based on the use of microbubbles with a huge acoustic resonance. The project is structured in two parts that only differ in the way bubbles are embedded in microfluidic environments:
1) Arrays of bubbles: Acoustic Laser
This first part is the development of an acoustic laser, based on microbubbles trapped in a microfluidic circuit. To obtain the conditions for an acoustic laser, arrays of microbubbles will be designed so that they bubbles pulsate in phase, reemitting their energy coherently. The applications are novel systems for high ultrasonic emission power, or meta-materials that store vibration energy.
2) Mobile “armoured” bubbles: swimming micro-robots remotely powered by ultrasound
The second part is the conception of ultrasonically activated microswimming devices, with microbubbles embedded within freely moving objects. Their application is to behave as carriers, such as drug carriers, activated at a distance, or to be active tracers that enhance mixing. Microswimmers are mechanical analogues to RFID devices (where electromagnetic vibration is converted into current), here sound is converted into motion at small scales.
Both parts include the same three complementary steps: step 1 is the 3D microfabrication of the geometry where bubbles are embedded, step 2 is their ultrasonic activation, and then step 3 is the optimisation of their resonance by a study of individual resonators.

The existence of intracellularly calcifying cyanobacteria may thus deeply modify our view on the role of cyanobacteria in the formation of modern and past carbonate deposits and the degree of control they achieve on this geochemically significant process. Moreover, since these cyanobacteria concentrate selectively Sr and Ba over Ca, it suggests the existence of processes that can alter the message conveyed by proxies such as Sr/Ca ratios in carbonates, classically used for paleoenvironmental reconstruction. Finally, such a biomineralization process, if globally significant may impact our view of how an ecosystem responds to external CO2 changes in particular by affecting most likely a key parameter such as the balance between organic carbon fixed by photosynthesis and inorganic carbon fixed by CaCO3 precipitation.
Here, I aim to bring a qualitative jump in the understanding of this process. The core of this project is to provide a detailed picture of intracellular calcification by cyanobacteria. This will be achieved by studying laboratory cultures of cyanobacteria, field samples of modern calcifying biofilms and ancient microbialites. Diverse tools from molecular biology, biochemistry, mineralogy and geochemistry will be used. Altogether these techniques will help unveiling the molecular and mineralogical mechanisms involved in cyanobacterial intracellular calcification, assessing the phylogenetic diversity of these cyanobacteria and the preservability of their traces in ancient rocks. My goal is to establish a unique expertise in the study of calcification by cyanobacteria, the scope of which can be developed and broadened in the future for the study of interactions between life and minerals.

Project Clusters And LENsing of Distant Sources

Host Institution (HI) UNIVERSITE LYON 1 CLAUDE BERNARD
Call Details Starting Grant (StG), PE9, ERC-2013-StG
Summary Some of the primary questions in extragalactic astronomy concern the formation and evolution of galaxies in the distant Universe. In particular, little is known about the less luminous (and therefore less massive) galaxy populations, which are currently missed from large observing surveys and could contribute significantly to the overall star formation happening at early times. One way to overcome the current observing limitations prior to the arrival of the future James Webb Space Telescope or the European Extremely Large Telescopes is to use the natural magnification of strong lensing clusters to look at distant sources with an improved sensitivity and resolution.
The aim of CALENDS is to build and study in great details a large sample of accurately-modelled, strongly lensed galaxies at high redshift (1<z<5) selected in the fields of massive clusters, and compare them with the more luminous or lower redshift populations. We will develop novel techniques in this process, in order to improve the accuracy of strong-lensing models and precisely determine the mass content of these clusters. By performing a systematic modelling of the cluster sample we will look into the relative distribution of baryons and dark matter as well as the amount of substructure in cluster cores. Regarding the population of lensed galaxies, we will study their global properties through a multiwavelength analysis covering the optical to millimeter domains, including spectroscopic information from MUSE and KMOS on the VLT, and ALMA.
We will look for scaling relations between the stellar, gas and dust parameters, and compare them with known relations for lower redshift and more massive galaxy samples. For the most extended sources, we will be able to spatially resolve their inner properties, and compare the results of individual regions with predictions from simulations. We will look into key physical processes: star formation, gas accretion, inflows and outflows, in these distant sources.

Summary "Heart failure is a serious clinical disorder that represents the primary cause of hospitalization and death in Europe and the United States. There is a dire need for new paradigms and therapeutic approaches for treatment of this devastating disease. The heart responds to mechanical load and various extracellular stimuli by hypertrophic growth and sustained pathological hypertrophy is a major clinical predictor of heart failure. A variety of stress-responsive signaling pathways promote cardiac hypertrophy, but the precise mechanisms that link these pathways to cardiac disease are only beginning to be unveiled. Signal transduction is traditionally concentrated on the protein coding part of the genome, but it is now appreciated that the protein coding part of the genome only constitutes 1.5% of the genome. RNA based mechanisms may provide a more complete understanding of the fundamentals of cellular signaling. As a proof-of-principle, we focus on a principal hypertrophic signaling cascade, cardiac calcineurin/NFAT signaling. Here we will establish that microRNAs are intimately interwoven with this signaling cascade, influence signaling strength by unexpected upstream mechanisms. Secondly, we will firmly establish that microRNA target genes critically contribute to genesis of heart failure. Third, the surprising stability of circulating microRNAs has opened the possibility to develop the next generation of biomarkers and provide unexpected mechanisms how genetic information is transported between cells in multicellular organs and fascilitate inter-cellular communication. Finally, microRNA-based therapeutic silencing is remarkably powerful and offers opportunities to specifically intervene in pathological signaling as the next generation heart failure therapeutics. CALMIRS aims to mine the wealth of these RNA mechanisms to enable the development of next generation RNA based signal transduction biology, with surprising new diagnostic and therapeutic opportunities."

Project Biophysical networks underlying the robustness of neuronal excitability

Host Institution (HI) INSTITUT NATIONAL DE LA SANTE ET DE LA RECHERCHE MEDICALE
Call Details Consolidator Grant (CoG), LS5, ERC-2013-CoG
Summary The mammalian nervous system is in some respect surprisingly robust to perturbations, as suggested by the virtually complete recovery of brain function after strokes or the pre-clinical asymptomatic phase of Parkinson’s disease. Ultimately though, cognitive and behavioral robustness relies on the ability of single neurons to cope with perturbations, and in particular to maintain a constant and reliable transfer of information.
So far, the main facet of robustness that has been studied at the neuronal level is homeostatic plasticity of electrical activity, which refers to the ability of neurons to stabilize their activity level in response to external perturbations. But neurons are also able to maintain their function when one of the major ion channels underlying their activity is deleted or mutated: the number of ion channel subtypes expressed by most excitable cells by far exceeds the minimal number of components necessary to achieve function, offering great potential for compensation when one of the channel’s function is altered. How ion channels are dynamically co-regulated to maintain the appropriate pattern of activity has yet to be determined.
In the current project, we will develop a systems-level approach to robustness of neuronal activity based on the combination of electrophysiology, microfluidic single-cell qPCR and computational modeling. We propose to i) characterize the electrical phenotype of dopaminergic neurons following different types of perturbations (ion channel KO, chronic pharmacological treatment), ii) measure the quantitatives changes in ion channel transcriptome (40 voltage-dependent ion channels) associated with these perturbations and iii) determine the mathematical relationships between quantitative changes in ion channel expression and electrical phenotype. Although focused on dopaminergic neurons, this project will provide a general framework that could be applied to any type of excitable cell to decipher its code of robustness.

Summary Clouds and precipitation play a crucial role in the Earth's energy balance, global atmospheric circulation and the water cycle. Despite their importance, clouds still pose the largest uncertainty in climate research.
I propose a new approach for studying anthropogenic effects on cloud fields and rain, tackling the challenge from both scientific ends: reductionism and systems approach. We will develop a novel research approach using observations and models interactively that will allow us to “peel apart” detailed physical processes. In parallel we will develop a systems view of cloud fields looking for Emergent Behavior rising out of the complexity, as the end result of all of the coupled processes. Better understanding of key processes on a detailed (reductionist) manner will enable us to formulate the important basic rules that control the field and to look for emergence of the overall effects.
We will merge ideas and methods from four different disciplines: remote sensing and radiative transfer, cloud physics, pattern recognition and computer vision and ideas developed in systems approach. All of this will be done against the backdrop of natural variability of meteorological systems.
The outcomes of this work will include fundamental new understanding of the coupled surface-aerosol-cloud-precipitation system. More importantly this work will emphasize the consequences of human actions on the environment, and how we change our climate and hydrological cycle as we input pollutants and transform the Earth’s surface. This work will open new horizons in cloud research by developing novel methods and employing the bulk knowledge of pattern recognition, complexity, networking and self organization to cloud and climate studies. We are proposing a long-term, open-ended program of study that will have scientific and societal relevance as long as human-caused influences continue, evolve and change.

Project Celiac disease: from lincRNAs to disease mechanism

Host Institution (HI) ACADEMISCH ZIEKENHUIS GRONINGEN
Call Details Advanced Grant (AdG), LS2, ERC-2012-ADG_20120314
Summary Celiac disease affects at least 1% of the world population. Its onset is triggered by gluten, a common dietary protein, however, its etiology is poorly understood. More than 80% of patients are not properly diagnosed and they therefore do not follow a gluten-free diet, thereby increasing their risk for disease-associated complications and early death. A better understanding of the disease biology would improve the diagnosis, prevention, and treatment of celiac disease.
This project investigates the disease mechanisms in celiac disease by using predisposing genes and genetic variants as disease initiating factors. Specifically, it will investigate if long, intergenic non-coding RNAs (lincRNAs) are causally involved in celiac disease pathogenesis by regulating protein-coding genes and pathways associated with the disease.
This project is based on two important observations by my group: (1) Our genetic studies, which led to identifying 39 celiac disease risk loci, suggest that the mechanism underlying the disease is largely governed by dysregulation of gene expression. (2) We uncovered a previously unrecognized role for lincRNAs that provides clues as to exactly how genetic variation causes disease, as this class of biologically important RNA molecules regulate gene expression.
The research will be performed in CD4+ T cells, a severely affected cell type in disease pathology. I will first use celiac disease-associated protein-coding genes to delineate their regulatory pathways and then study the transcriptional programs of lincRNAs present in celiac disease loci. Next I will combine the information and investigate if the expressed lincRNAs modulate the pathways and affect T cell function, thereby discovering if lincRNAs are a missing link between non-coding genetic variation and protein-coding genes. Our findings may well lead to potential therapeutic targets and provide a solid scientific basis for new diagnostic markers, particularly biomarkers, based on genetics.

Summary "Spatially distributed multi-agent networks have been used successfully to model a wide range of natural, social and engineered complex systems, such as animal groups, online communities and electric power grids. In various contexts, it is crucial to introduce control actions into such networks to either achieve desired collective dynamics or test the understanding of the systems’ behavior. However, controlling such systems is extremely challenging due to agents’ complicated sensing, communication and control interactions that are distributed in space. Systematic methodologies to attack this challenge are in urgent need, especially when vast efforts are being made in multiple disciplines to apply the model of complex multi-agent networks.
The goal of the project is twofold. First, understand whether a complex multi-agent network can be controlled effectively when the agents can only sense and communicate locally. Second, provide methodologies to implement distributed control in typical spatially distributed complex multi-agent networks. The project requires integrated skills since both rigorous theoretical analysis and novel empirical explorations are necessary.
The research methods that I plan to adopt have two distinguishing features. First, I use tools from algebraic graph theory and complex network theory to investigate the impact of network topologies on the systems’ controller performances characterized by mathematical control theory. Second, I utilize a homemade robotic-fish testbed to implement various multi-agent control algorithms. The unique combination of theoretical and empirical studies is expected to lead to breakthroughs in developing an integrated set of principles and techniques to control effectively spatially distributed multi-agent networks. The expected results will make original contributions to control engineering and robotics, and inspire innovative research methods in theoretical biology and theoretical sociology."

Project Cell-Cell fusion in fertilization and developmental biology: a structural biology approach

Host Institution (HI) INSTITUT PASTEUR
Call Details Advanced Grant (AdG), LS1, ERC-2013-ADG
Summary My group has made seminal contributions in the past toward understanding the mechanism of membrane fusion used by enveloped viruses to infect a cell. This aim of this ERC grant proposal is to achieve similar breakthroughs in understanding fusion between cells, both during fertilization and organogenesis. This proposal is based in recent important results not yet published.
We have determined the crystal structure of the C. elegans protein EFF-1, a member of the “fusion family” (FF). EFF-1 is responsible for a cell-cell fusion event during skin formation in the nematode. Strikingly, the crystal structure shows that EFF-1 is homologous to the “Class II” viral protein fusogens, thus indicating that they have diverged from a common ancestor. The observed homology could not be identified by other means because the proteins have diverged to the point where no remnants of sequence similarity are left, yet the tertiary and quaternary organization is the same. However, the homotypic fusion mechanism of EFF-1 is clearly different to that of viral fusion proteins.
This proposal intends to build on the momentum generated by this exciting discovery, in an attempt to cast light into the fusion mechanism of FF proteins. We will reconstitute them in artificial liposomes and will also follow them within cells with the use of light microscopy. We will also focus in determining the crystal structure of the monomeric pre-fusion form of EFF-1,and of the intact trans-membrane post fusion trimer. In parallel, we want to make use the experience accumulated over the years in crystallizing viral glycoproteins, to apply it to the conserved family of HAP2/GSC1 proteins involved in fusion of gametes during fertilization. These proteins exhibit a similar pattern of secondary structure elements in the ectodomain as class II proteins, but only a crystallographic analysis can identify a possible structural homology and provide the basis to understand the molecular mechanisms of cell-cell fusion.

Summary We shall develop a microfluidic and microsystems toolbox allowing the construction and study of complex cellular assemblies (“tissue or organ mimics on chip”), in a highly controlled and parallelized way. This platform will allow the selection of specific cells from one or several populations, their deterministic positioning and/or connection relative to each other, yielding functional assemblies with a degree of complexity, determinism and physiological realism unavailable to current in vitro systems We shall in particular develop “semi-3D” architectures, reproducing the local 3D arrangement of tissues, but presenting at mesoscale a planar and periodic arrangement facilitating high resolution stimulation and recording. This will provide biologists and clinicians with new experimental models able to bridge the gap between current in vitro systems, in which cells can be observed in parallel at high resolution, but lack the highly ordered architecture present in living systems, and in vivo models, in which observation and stimulation means are more limited. This development will follow a functional approach, and gather competences and concepts from micr-nano-systems, surface science, hydrodynamics, soft matter and biology. We shall validate it on three specific applications, the sorting and study of circulating tumour cells for understanding metastases, the creation of “miniguts”, artificial intestinal tissue, for applications in developmental biology and cancerogenesis, and the in vitro construction of active and connected neuron arrays, for studying the molecular mechanisms of Alzheimer, and signal processing by neuron networks. This platform will also open new routes for drug testing, replacing animal models and reducing the health and economic risk of clinical tests, developmental biology , stem cells research. and regenerative medicine.

Summary "Clonal evolution represents a driving force for cancer cells and a major challenge for therapy. There is a long-standing knowledge that clonal diversification and selection allows cancer cells to pass through distinct steps of transformation. More recently has emerged the concept that ""more malignant"" leukemia subclones can persist after treatment leading to relapse. My research is focused on two diseases which represent privileged models to study clonal evolution: Fanconi anemia (FA), which is a genetic condition predisposing to acute leukemia, and T-cell acute lymphoblastic leukemia (T-ALL), an aggressive leukemia which frequently relapses. The goal of this project is to decipher the crucial molecular and cellular events that drive gain of malignancy and to design new strategies to follow up and treat the patients. Specifically, we aim to:
1. Identify the key pathways involved in leukemia progression at two major steps: from pre-leukemia to overt leukemia (in FA), and from primary diagnosis to relapse (in T-ALL). This aim will use high-throughput molecular profiling and functional characterization of longitudinal samples from patients.
2. Model leukemia progression in vivo to functionally validate these pathways. We have developed read-outs based on gene silencing in human primary cells from patients followed by leukemia monitoring in immunodeficient mice.
3. Define new strategies to prevent the transition towards acute leukemia in pre-leukemic states in FA patients. We will develop new markers for transformation that should help in monitoring therapeutic intervention.
4. Test drugs in pre-clinical models to target critical pathways of relapsed ALL. We will use xenografted T-ALL which recapitulates leukemia progression.
Completion of this innovative transversal project should markedly improve the knowledge on tumor progression and lead to new strategies to prevent, early detect and/or treat relapse, with the final objective to cure more patients."

Project What chemicals do for youths in their everyday lives
Researcher (PI) Anita Petra Hardon
Host Institution (HI) UNIVERSITEIT VAN AMSTERDAM
Call Details Advanced Grant (AdG), SH2, ERC-2012-ADG_20120411
Summary The everyday lives of contemporary youths are awash with chemicals and pharmaceutical compounds to boost pleasure, moods, sexual performance, vitality, appearance and health. Nevertheless, most studies of chemical use among young people have focused on the abuse of specific recreational drugs and their role within deviant youth sub-cultures. Instead of explaining drug abuse with the purpose of controlling it, this project aims to examine the pervasive use of chemicals from the perspectives of youths themselves. It aims to understand what chemical and pharmaceutical substances, and not only illicit narcotics, ‘do’ for youths. How are chemicals a part of their everyday lives? What role do they play in calming their fears or in achieving their dreams and aspirations? How can we understand the ways in which chemicals affect their bodies and minds?
The theoretical innovation promised by this project lies in its combining of disciplines – most notably medical anthropology, science and technology studies and youth studies – to formulate a new groundbreaking framework for understanding the complex sociality of chemicals in youths’ everyday lives. The framework will have both scientific and societal impact.
Ethnographic research will be conducted in four medium-sized cities: Marseille in France, Amsterdam in the Netherlands, Makassar in Indonesia, and Batangas in the Philippines.

Project Challenges in Extraction and Separation of Sources
Researcher (PI) Christian Patrice Jutten
Host Institution (HI) UNIVERSITE GRENOBLE ALPES
Call Details Advanced Grant (AdG), PE7, ERC-2012-ADG_20120216
Summary Separation/extraction of sources are wide concepts in information sciences, since sensors provide information mixing and an essential step consists in separating or extracting useful information from unuseful one, called noise. In this project, we consider three challenges.
The first one is the multimodality. Indeed, with the multiplication of kinds of sensors, in many areas like biomedical signal processing, hyperspectral imaging, etc. there are many ways for recording the same physical phenomenon leading thus to multimodal data. Multimodality has been studied in the framework of human-computer interface or in data fusion, but never at the signal level. The objective is to provide a general framework for modeling classical multimodal properties, like complementarity, redundancy, equivalence, etc. as of function of source signals.
The second challenge is nonlinearity. Indeed, there exist a few cases where the mixtures are essentially nonlinear, e.g. with chemical sensors. The main objective is to enlarge results on identifiability conditions for new classes of nonlinearities and priors on sources.
The third challenge is the data size. For high-dimension data (e.g. EEG or MRI in brain imaging), separating all the sources is neither tractable nor relevant, since one would like to only extract the useful sources. Conversely, for a small number of sensors, especially smaller than the number of sources, it is again necessary to only focus on the useful signals. The main objective is to develop generic approaches able to only extract useful signals, based on simple reference signal, modeling weak properties of the useful signal.
Finally, validation and relevant modeling must be based on actual signals and problems. In this project, theoretical results and algorithms will be developed in interaction with applications in biomedical engineering (brain-computer interface, EEG, fMRI), chemical engineering, audio-visual scene analysis and hyperspectral imaging.

Project From Made in China to Created in China - A Comparative Study of Creative Practice and Production in Contemporary China
Researcher (PI) Bastiaan Jeroen De Kloet
Host Institution (HI) UNIVERSITEIT VAN AMSTERDAM
Call Details Consolidator Grant (CoG), SH5, ERC-2013-CoG
Summary With its emergence as a global power, China aspires to move from a “made in China” towards a “created in China” country. Creativity and culture have become a crucial source for innovation and financial growth, but are also mobilised to promote a new and open China to both the citizenry as well as the outside world. They are part of what is termed China’s “soft power.”
What does creativity mean in the context of China, and what does it do? When both the state and profoundly globalised creative industries are so deeply implicated in the promotion of creativity, what are the possibilities of criticality, if any? Whereas creativity has been extensively researched in the fields of psychology, law and neurosciences, scholarship in the humanities has by and large side-tracked the thorny issue of creativity. Yet, the worldwide resurgence of the term under the banner of creative industries makes it all the more urgent to develop a theory of creativity. This project understands creativity as a textual, a social as well as a heritage practice. It aims to analyse claims of creativity in different cultural practices, and to analyse how emerging creativities in China are part of tactics of governmentality and disable or enable possibilities of criticality.
Using a comparative, multi-disciplinary, multi-method and multi-sited research design, five subprojects analyse (1) contemporary art, (2) calligraphy, (3) independent documentary cinema, (4) television from Hunan Satellite TV and (5) “fake” (shanzhai) art. By including both popular and high arts, by including both more Westernized as well as more specifically Chinese art forms, by including both the “real” as well as the “fake,” by studying different localities, and by mobilising methods from both the social sciences and the humanities, this project is pushing the notion of comparative research to a new level.

Summary "Communication between the nervous and the immune system is pivotal for maintaining homeostasis and ensuring rapid and efficient reaction to stress and infection insults. The emergence of microRNAs (miRs) as regulators of gene expression and of acetylcholine (ACh) signalling as regulator of anxiety and inflammation provides a model for studying this interaction. My hypothesis is that 1) a specific sub-group of miRs, designated ""CholinomiRs"", may silence multiple target genes in the neuro-immune interface; 2) these miRs compete with each other on the interaction with their targets, and 3) mutations interfering with miR binding lead to inherited susceptibility to anxiety and inflammation disorders by modifying these interactions. Our preliminary findings have shown that by targeting acetylcholinesterase (AChE), CholinomiR-132 can intensify acute stress, resolve intestinal inflammation and change post-ischemic stroke responses. Further, we have identified clustered single nucleotide polymorphisms (SNPs) interfering with AChE silencing by several miRs which associate with elevated trait anxiety, blood pressure and inflammation. To further study miR regulators of ACh signalling, I plan to: (1) Identify anxiety and inflammation-induced changes in CholinomiRs and their targets in challenged brain and immune cells. (2) Establish the roles of these targets for one selected CholinomiR by tissue-specific manipulations. (3) Study primate-specific CholinomiRs by continued human DNA screens to identify SNPs and in ""humanized"" mice with knocked-in human AChE and transgenic CholinomiR-608. (4) Test if therapeutic modulation of aberrant CholinomiR expression can restore homeostasis. This research will clarify how miRs interact with each other in health and disease, introduce the dimension of complexity of multi-target competition and miR interactions and make a conceptual change in miRs research while enhancing the ability to intervene with diseases involving impaired ACh signalling."

Host Institution (HI) ACADEMISCH ZIEKENHUIS LEIDEN
Call Details Consolidator Grant (CoG), LS2, ERC-2013-CoG
Summary "Our cells receive tens of thousands of different DNA lesions per day. Failure to repair these lesions will lead to cell death, mutations and genome instability, which contribute to human diseases such as neurodegenerative disorders and cancer. Efficient recognition and repair of DNA damage, however, is complicated by the fact that genomic DNA is packaged, through histone and non-histone proteins, into a condensed structure called chromatin. The DNA repair machinery has to circumvent this barrier to gain access to the damaged DNA and repair the lesions. Our recent work suggests that chromatin-modifying enzymes (CME) help to overcome this barrier at sites of DNA damage. However, the identity of these CME, their mode of action and interconnections with DNA repair pathways remain largely enigmatic. The aim of this project is to systematically identify and characterize the CME that operate during DNA repair processes in both yeast and human cells. To reach this goal we will use a cross-disciplinary approach that combines novel and cutting-edge genomics approaches with bioinformatics, genetics, biochemistry and high-resolution microscopy. Epigenetics-IDentifier (Epi-ID) will be used as a tool to unveil novel CME, whereas RNAi-interference and genetic interaction mapping studies will pinpoint the CME that may potentially regulate repair of DNA damage. A series of functional assays will eventually characterize their role in distinct DNA repair pathways, focusing on those that counteract DNA strand breaks and replication stress. Together these studies will provide insight into how CME assist cells to repair DNA damage in chromatin and inform on the relevance of CME to maintain genome stability and counteract human diseases."

Call Details Advanced Grant (AdG), LS2, ERC-2013-ADG
Summary Epigenetic mechanisms play an important role in regulating and maintaining the functionality of cells and have been implicated in a wide range of human diseases. Histone proteins that form the protein core of nucleosomes are subject to a bewildering array of covalent and structural modifications, which can repress, permit, or promote transcription. These modifications can be added and removed by specialized complexes that are recruited by other covalent modifications, by transcription factors, or by the transcriptional machinery. Advances in genomics led to comprehensive mapping of the ``epigenome'' in a range of tissues and organisms. These maps established the tight connection between histone modifications and transcription programs. These static charts, however, are less successful at uncovering the underlying mechanisms, logic, and function of histone modifications in establishing and maintaining transcriptional programs. Our premise is that we can answer these basic questions by observing the effect of genetic perturbations on the dynamics of both chromatin state and transcriptional activity. We aim to dissect the chromatin-transcription system in a systematic manner by building on our extensive experience in modeling and analysis, and a unique high-throughput experimental system we established in my lab.
We plan to use the budding yeast model organism, which allows for
efficient genetic and experimental manipulations. We will combine two technologies: (1) high-throughput measurements of single-cell
transcriptional output using fluorescence reporters; and (2) high-throughput immunoprecipitation sequencing assays to map chromatin state. Measuring with these the dynamics of response to stimuli under different genetic backgrounds and using advanced stochastic network models, we will chart detailed mechanisms that are opaque to current approaches and elucidate the general principles that govern the interplay between chromatin and transcription.

Summary "Electronic spins are usually detected by their interaction with electromagnetic fields at microwave frequencies. Since this interaction is very weak, only large ensembles of spins can be detected. In circuit quantum electrodynamics (cQED) on the other hand, artificial superconducting atoms are made to interact strongly with microwave fields at the single photon level, and quantum-limited detection of few-photon microwave signals has been developed.
The goal of this project is to apply the concepts and techniques of cQED to the detection and manipulation of electronic and nuclear spins, in order to reach a novel regime in which a single electronic spin strongly interacts with single microwave photons. This will lead to
1) A considerable enhancement of the sensitivity of spin detection by microwave methods. We plan to detect resonantly single electronic spins in a few milliseconds. This could enable A) to perform electron spin resonance spectroscopy on few-molecule samples B) to measure the magnetization of various nano-objects at millikelvin temperatures, using the spin as a magnetic sensor with nanoscale resolution.
2) Applications in quantum information science. Strong interaction with microwave fields at the quantum level will enable the generation of entangled states of distant individual electronic and nuclear spins, using superconducting qubits, resonators and microwave photons, as “quantum data buses” mediating the entanglement. Since spins can have coherence times in the seconds range, this could pave the way towards a scalable implementation of quantum information processing protocols.
These ideas will be primarily implemented with NV centers in diamond, which are electronic spins with properties suitable for the project."

Summary We propose to develop a new scheme for detecting and manipulating exotic states formed by combinations of conductors with different dimensionalities and/or electronic orders. For that purpose, we will use tools of cavity quantum electrodynamics to study in a very controlled way the interaction of light and this exotic matter.
Our experiments will be implemented with nanowires connected to normal, ferromagnetic or superconducting electrodes embedded in high finesse on-chip superconducting photonic cavities. The experimental technique proposed here will inaugurate a novel method for investigating the spectroscopy and the dynamics of tailored nano-systems.
During the project, we will focus on three key experiments. We will demonstrate the strong coupling between a single spin and cavity photons, bringing spin quantum bits a step closer to scalability. We will probe coherence in Cooper pair splitters using lasing and sub-radiance. Finally, we will probe the non-local nature of Majorana bound states predicted to appear at the edges of topological superconductors via their interaction with cavity photons.

Summary The overall objective is to fully understand the Chiral Induced Spin Selectivity (CISS) effect, which was discovered recently. It was found that the transmission or conduction of electrons through chiral molecules is spin dependent. The CISS effect is a change in the pradigm that assumed that any spin manipulation requiers magnetic materials or materials with high spin-orbit coupling. These unexpected new findings open new possibilities for applying chiral molecules in spintronics applications and may provide new insights on electron transfer processes in Biology.
The specific goals of the proposed research are
(i) To establish the parameters that affect the magnitude of the CISS effect.
(ii) To demonstrate spintronics devices (memory and transistors) that are based on the CISS effect.
(iii) To investigate the role of CISS in electron transfer in biology related systems.
The experiments will be performed applying a combination of experimental methods including photoelectron spectroscopy, single molecule conduction, light-induced electron transfer, and spin specific conduction through magneto-electric devices.
The project has a potential to have very large impact on various fields from Physics to Biology. It will result in the establishment of chiral organic molecules as a new substrate for wide range of spintronics related applications including magnetic memory, and in determining whether spins play a role in electron transfer processes in biology.

Summary In this project, the basal ganglia are defined as actor-critic reinforcement learning networks that aim at an optimal tradeoff between the maximization of future cumulative rewards and the minimization of the cost (the reinforcement driven multi objective optimization RDMOO model).
This computational model will be tested by multiple neuron recordings in the major basal ganglia structures of monkeys engaged in a similar behavioral task. We will further validate the RMDOO computational model of the basal ganglia by extending our previous studies of neural activity in the MPTP primate model of Parkinson's disease to a primate model of central serotonin depletion and emotional dysregulation disorders. The findings in the primate model of emotional dysregulation will then be compared to electrophysiological recordings carried out in human patients with treatment-resistant major depression and obsessive compulsive disorder during deep brain stimulation (DBS) procedures. I aim to find neural signatures (e.g., synchronous gamma oscillations in the actor part of the basal ganglia as predicted by the RMDOO model) characterizing these emotional disorders and to use them as triggers for closed loop adaptive DBS. Our working hypothesis holds that, as for the MPTP model of Parkinson's disease, closed loop DBS will lead to greater amelioration of the emotional deficits in serotonin depleted monkeys.
This project incorporates extensive collaborations with a team of neurosurgeons, neurologists, psychiatrists, and computer science/ neural network researchers. If successful, the findings will provide a firm understanding of the computational physiology of the basal ganglia networks and their disorders. Importantly, they will pave the way to better treatment of human patients with severe mental disorders.
Summary
In this project, the basal ganglia are defined as actor-critic reinforcement learning networks that aim at an optimal tradeoff between the maximization of future cumulative rewards and the minimization of the cost (the reinforcement driven multi objective optimization RDMOO model).
This computational model will be tested by multiple neuron recordings in the major basal ganglia structures of monkeys engaged in a similar behavioral task. We will further validate the RMDOO computational model of the basal ganglia by extending our previous studies of neural activity in the MPTP primate model of Parkinson's disease to a primate model of central serotonin depletion and emotional dysregulation disorders. The findings in the primate model of emotional dysregulation will then be compared to electrophysiological recordings carried out in human patients with treatment-resistant major depression and obsessive compulsive disorder during deep brain stimulation (DBS) procedures.

Project Selective Carbon-Carbon Bond Activation: A Wellspring of Untapped Reactivity
Researcher (PI) Ilan Marek
Host Institution (HI) TECHNION - ISRAEL INSTITUTE OF TECHNOLOGY
Call Details Advanced Grant (AdG), PE5, ERC-2013-ADG
Summary The creation of new molecular entities and subsequent exploitation of their properties is central to a broad spectrum of research disciplines from medicine to materials. Most –if not all- of the efforts of organic chemists were directed to the development of creative strategies to built carbon-carbon and carbon-heteroatom bonds in a predictable and efficient manner. But is the creation of new bonds the only approach that organic chemistry should follow? Could we design the synthesis of challenging molecular skeleton no more through the construction of carbon-carbon bonds but rather through selective cleavage of carbon-carbon bonds (C-C bond activation)? The goal of this work is to develop powerful synthetic approaches for the selective C-C bond activation and demonstrate that it has the potential to be a general principle in organic synthesis for the regio-, diastereo- and even enantiomerically enriched preparation of adducts despite that C-C single bonds belong among the least reactive functional groups in chemistry. The realization of this synthetic potential requires the ability to functionalize selectively one C-C bond in compounds containing many such bonds and an array of functional groups. This site selective C-C bond activation is one of the greatest challenges that must be met to be used widely in complex-molecular synthesis. To emphasize the practicality of C-C bond activation, we will prepare in a single-pot operation challenging molecular framework possessing various stereogenic centers from very simple starting materials through selective C-C bond activation. Ideally, alkenes will be in-situ transformed into alkanes that will subsequently undergo the C-C activation even in the presence of functional group. This work will lead to ground-breaking advances when non-strained cycloalkanes (cyclopentane, cyclohexane) will undergo this smooth C-C bond activation with friendly and non toxic organometallic species.

Project A Diagonal Approach to CO2 Recycling to Fine Chemicals

Call Details Starting Grant (StG), PE5, ERC-2013-StG
Summary Because fossil resources are a limited feedstock and their use results in the accumulation of atmospheric CO2, the organic chemistry industry will face important challenges in the next decades to find alternative feedstocks. New methods for the recycling of CO2 are therefore needed, to use CO2 as a carbon source for the production of organic chemicals. Yet, CO2 is difficult to transform and only 3 chemical processes recycling CO2 have been industrialized to date. To tackle this problem, my idea is to design novel catalytic transformations where CO2 is reacted, in a single step, with a functionalizing reagent and a reductant that can be independently modified, to produce a large spectrum of molecules. The proof of concept for this new “diagonal approach” has been established in 2012, in my team, with a new reaction able to co-recycle CO2 and a chemical waste of the silicones industry (PMHS) to convert amines to formamides. The goal of this proposal is to develop new diagonal reactions to enable the use of CO2 for the synthesis of amines, esters and amides, which are currently obtained from fossil materials. The novel catalytic reactions will be applied to the production of important molecules: methylamines, acrylamide and methyladipic acid. The methodology will rely on the development of molecular catalysts able to promote the reductive functionalization of CO2 in the presence of H2 or hydrosilanes. Rational design of efficient catalysts will be performed based on theoretical and experimental mechanistic investigations and utilized for the production of industrially important chemicals. Overall, this proposal will contribute to achieving sustainability in the chemical industry. The results will also increase our understanding of CO2 activation and provide invaluable insights into the basic modes of action of organocatalysts in reduction chemistry. They will serve the scientific community involved in the field of organocatalysis, green chemistry and energy storage.

Project Robust Codes from Higher Dimesional Expanders

Host Institution (HI) BAR ILAN UNIVERSITY
Call Details Starting Grant (StG), PE6, ERC-2013-StG
Summary Error correcting codes play a fundamental role in computer science. Good codes are codes with rate and distance that are asymptotically optimal. Some of the most successful good codes are constructed using expander graphs. In recent years a new notion of {\em robust} error correcting codes, known as locally testable codes (LTCs), has emerged. Locally testable codes are codes in which a proximity of a vector to an error correcting code can be achieved by probing the vector in {\em constant} many locations (independent of its length). LTCs are at the heart of Probabilistically Checkable Proofs (PCPs) and their construction has been sought since the discovery of the PCP theorem in the early 1990s.
Despite 20 years of research, it is still widely open whether good locally testable codes exist. LTCs present completely new challenge to the field of error correcting codes. In the old paradigm a random code is a good code and the main focus was to construct explicit codes that imitate the random code. However, a random code is not an LTC. Thus, contrary to traditional codes, there are no natural candidates for LTCs. The known constructions of robust codes are ad hoc, and there is a lack of theory that explains their existence.
The goal of the current research plan is to harness the emerging field of higher dimensional expanders and their topological properties for a systematic study of robust error correcting codes. Higher dimensional expanders are natural candidates for obtaining robust codes since they offer a strong form of redundancy that is essential for robustness. Such form of redundancy is lacking by their one dimensional analogue (i.e., expander graphs). Hence, the known expander codes are not robust. We expect that our study will draw new connections between error correcting codes, high dimensional expanders, topology and probability that will shed new light on these fields, and in particular, will advance the constructing of good and robust codes.

Summary Cold gases of electronically excited Rydberg atoms and groundstate polar molecules have generated considerable interest in cold matter physics, by introducing for the first time many-body systems with interactions which are both long-range and tunable with external fields. The overall objective of this proposal is (i) the development of theoretical ideas and tools for the understanding and control of non-equilibrium dynamics in these diverse systems and in their mixtures, including dissipative effects leading to cooling, and (ii) to analyse emerging fundamental phenomena in the classical and quantum regimes of strong interactions, leading to innovative simulations and experiments of complex classical and quantum systems. The project is divided into three parts, with strong overlap:
1) Rydberg atom dynamics: The study of complex open-system dynamics in gases of laser-driven Rydberg atoms, including the study of the effects and control of dissipation and decoherence from spontaneous emission in strongly interacting gases.
2) Cooling of complex molecules in atom-molecule mixtures: The theoretical investigation of novel ways to perform cooling towards quantum degeneracy of generic, comparatively complex molecules, beyond bialkali ones, in mixtures of groundstate molecules and of Rydberg-excited atoms.
3) Simulations of strongly interacting many-body systems at the quantum/classical crossover: Atomistic characterization of formation and dynamics of formation of strongly correlated phases with long-range interactions.
For each of these subjects, the objectives are at the cutting edge of fundamental atomic and molecular science and technology.

Summary All cancers arise due to alterations in their genomes. Although insight into the genetic lesions in tumours by genome sequencing does already assist in selecting some drug regimens, it rarely results in disease eradication due to the emergence of drug-resistant clones. More sophisticated combination therapies in which several oncogenic pathways are targeted simultaneously or in a particular sequence are believed to hold more promise. However, at present we are unable to extract and interpret the necessary information from tumours to predict which drug regimen will be most adequate. The genetic make-up of the individual, the heterogeneity of the tumour, epigenetic alterations, cell-of-origin of the tumour, and complex interactions between tumour cells and stromal cells appear important confounding factors influencing response. In addition, we are still ignorant of many of the intricate complexities of signalling networks in cells and how tumours exploit these to acquire drug resistance.
It is the ambition of the team formed by members of the Netherlands Cancer Institute (NKI) and the Cancer Genome Project at the Wellcome Trust Sanger Institute (WTSI) to unravel the genomic and phenotypic complexity of human cancers in order to identify optimal drug combinations for personalized cancer therapy. Our integrated approach will entail (i) deep sequencing of human tumours and cognate mouse tumours; (ii) drug screens in a 1000+ fully characterized tumour cell line panel; (iii) high-throughput in vitro and in vivo shRNA and cDNA drug resistance and enhancement screens; (iv) computational analysis of the acquired data, leading to significant response predictions; (v) rigorous validation of these predictions in genetically engineered mouse models and patient-derived xenografts. This integrated effort is expected to yield a number of combination therapies and companion-diagnostics biomarkers that will be further explored in our existing clinical trial networks.

Call Details Starting Grant (StG), PE10, ERC-2012-StG_20111012
Summary Climate change and associated water cycle modifications have a strong impact on polar ice sheets through their influence on the global sea-level. The most promising tool for reconstructing temperature and water cycle evolution in Antarctica is to use water isotopic records in ice cores. Still, interpreting these records is nowadays limited by known biases linked to a too simple description of isotopic fractionations and cloud microphysics. Another key issue in this region is the stratosphere-troposphere flux influencing both the chemistry of ozone and decadal climate change. Data are lacking for constraining such flux even on the recent period (100 years). COMBINISO aims at making use of innovative methods combining measurements of the 5 major water isotopes (H217O, H218O, HTO, HDO, H2O) and global modelling to address the following key points: 1- Provide a strongly improved physical frame for interpretation of water isotopic records in polar regions; 2- Provide a quantitative picture of Antarctica temperature changes and links with the tropospheric water cycle prior to the instrumental period; 3- Quantify recent variability of the stratosphere water vapor input.
The proposed method, based on strong experimental – modelling interaction, includes innovative tools such as (1) the intensive use of the recently developed triple isotopic composition of oxygen in water for constraining water isotopic fractionation, hydrological cycle organisation and potentially stratospheric water input, (2) the development of a laser spectroscopy instrument to accurately measure this parameter in water vapour, (3) modelling development including stratospheric tracers (e.g. HTO and 10Be) in addition to water isotopes in Atmospheric General Circulation Models equipped with a detailed description of the stratosphere, (4) a first documentation of climate, hydrological cycle and stratospheric input in Antarctica through combined measurements of isotopes in ice cores for the last 100 years.

Summary When patients recover from coma, determining their level of consciousness can be difficult, even for an experienced clinician. Our goal is to provide a Consciousness Monitoring Index: a robust method to detect and quantitatively monitor the extent to which a human being is or is not conscious. Using electrodes attached to the scalp, we monitor the electro-encephalographic (EEG) signal which reflects ongoing brain activity. We have discovered and filed a patent for several mathematical indices which can be easily computed from the EEG, and which, alone or in combination, provide a continuous indicator of whether the person is or is not conscious. Our empirical studies in patients with coma, vegetative state show that our EEG-based markers can (1) accurately determine whether a patient is or not conscious at the time of testing; (2) establish how consciousness fluctuates from moment to moment; (3) predict, in a statistical manner, the capacity of the patient to recover consciousness.
In this project, we propose to establish the scientific validity, technical feasibility, market potential, business model, and legal context for two distinct services that could be provided: (1) an off-line computer-based service for automated analysis of existing clinical EEG recordings, taking the form of a web server where clinicians would upload these data and receive a summary of indicators of consciousness. (2) an on-line bedside monitor of consciousness, taking the form of a tablet PC and dedicated EEG amplifier constantly displaying a scrolling view of indicators of consciousness, for real-time use by clinicians and by families, possibly with real-time feedback to patients.
Our application is primarily intended for adult patients with disorders of consciousness, their doctors and their families, but its market could be much larger, and we will explore its possible extension to anaesthesia, sleep disorders, epilepsy, pediatric populations, professional and personal use.

The goal of the proposed research program is to integrate the worlds of organic and inorganic colloidal chemistry by means of manipulating chemical reactivities and synthesizing novel molecules and nanostructures inside synthetic confined environments created using novel, unconventional approaches based on inorganic, nanostructured building blocks. The three types of confined spaces we propose are as follows: 1) nanopores within reversibly self-assembling colloidal crystals (""dynamic nanoflasks""), 2) cavities of bowl-shaped metallic nanoparticles (NPs), and 3) surfaces of spherical NPs. By taking advantage of these unique tools, we will attempt to develop, respectively, 1) a conceptually new method for catalyzing chemical reactions using light, 2) nanoscale inclusion chemistry (a field based on host-guest ""complexes"" assembled form nanosized components) and 3) to use NPs as platforms for the development of new organic reactions. While these objectives are predominantly of a fundamental nature, they can easily evolve into a variety of practical applications. Specifically, we will pursue diverse goals such as the preparation of 1) a new family of inverse opals (with potentially fascinating optical and mechanical properties), 2) artificial chaperones (NPs assisting in protein folding), and 3) size- and shape-controlled polymeric vesicles. Overall, it is believed that this marriage of organic and colloidal chemistry has the potential to change the fundamental way we perform chemical reactions, paving the way to the discovery of new phenomena and unique structures."

Project Core/Shell nanoparticle electrocatalysts for fuel cell applications: probing the market potential of Atomic Layer Deposition (ALD) coatings
Researcher (PI) Jan Rudolf VAN OMMEN
Host Institution (HI) TECHNISCHE UNIVERSITEIT DELFT
Call Details Proof of Concept (PoC), PC1, ERC-2012-PoC
Summary Fuel cell systems are high-efficiency, low-emission energy conversion modules for transportation, stationary and portable applications. Especially for automotive applications, low-temperature proton exchange membrane (PEM) fuel cells are considered a key-stone solution, as they can effectively reduce greenhouse gases emissions. A major barrier for the market penetration of these systems is the material scarcity of precious metals used for the fabrication of the electrocatalyst, a core-component of the system.
Achieving increased performance in terms of catalytic activity and stability (corrosion resistance) while decreasing the cost, can be realized by a drastic redesign of the catalyst fabrication process using Atomic Layer Deposition (ALD) of nanoparticles. Using the understanding of the ALD coating processes obtained in the ERC-StG project AggloNanoCoat, the technique’s potential for producing tailored yet inexpensive core/shell nanoparticles for advanced catalysis applications has been identified. The innovative process characteristics (precise surface modification, mild operating conditions, scale-up potential and minimization of environmental footprint) clearly form a strong pre-commercialization starting-point. The next required step is the assessment of the market potential, effectively bridging nanoparticle ALD and the fuel cell catalyst manufacturing section.

Summary
Fuel cell systems are high-efficiency, low-emission energy conversion modules for transportation, stationary and portable applications. Especially for automotive applications, low-temperature proton exchange membrane (PEM) fuel cells are considered a key-stone solution, as they can effectively reduce greenhouse gases emissions. A major barrier for the market penetration of these systems is the material scarcity of precious metals used for the fabrication of the electrocatalyst, a core-component of the system.
Achieving increased performance in terms of catalytic activity and stability (corrosion resistance) while decreasing the cost, can be realized by a drastic redesign of the catalyst fabrication process using Atomic Layer Deposition (ALD) of nanoparticles. Using the understanding of the ALD coating processes obtained in the ERC-StG project AggloNanoCoat, the technique’s potential for producing tailored yet inexpensive core/shell nanoparticles for advanced catalysis applications has been identified. The innovative process characteristics (precise surface modification, mild operating conditions, scale-up potential and minimization of environmental footprint) clearly form a strong pre-commercialization starting-point. The next required step is the assessment of the market potential, effectively bridging nanoparticle ALD and the fuel cell catalyst manufacturing section.

Summary "In an era of worldwide increasing inequalities, key social science issues about the production and reproduction of social inequality gain renewed attention. One central issue is the role played by demographic events and trajectories in producing and reproducing inequalities. This proposal examines this issue by studying the relationships between the experience of childhood social disadvantage, demographic decision-making during young adulthood and later-life economic, social and health outcomes from a comparative perspective. The key contribution of this proposal is that it studies cross-national variation in the strength of these relationships and focuses on one general explanation: the strength of the relationships depend on the opportunities that societies offer to abate the adverse impact of economic and social deprivation. I will pay attention to three aspects of the national context: (1) economic aspects, like the level of economic development and growth in a country, (2) cultural aspects, like the extent to which strong norms on family-related behaviour are operative, and (3) aspects of institutional arrangements, like the openness of the educational system, and existing family policies and general social policies. I will test whether the strength of the links between childhood disadvantage, young adult demographic behaviour and subsequent outcomes depend on these three aspects of the ‘contexts of opportunity’. To test these ideas, I will use retrospective and prospective data from the Generations and Gender Programme, and use a combination of sophisticated methods, including multi-level analysis, latent variable analysis and sequence analysis. In doing so, this project will elucidate the role of demography in the reproduction of inequalities and highlight key opportunity structures that influence the strength of the relevant links between social background, young adult demographic behaviours and subsequent outcomes."

Project Clinical ultrasound platform for the quantitative and longitudinal imaging of theranostics and cellular therapy
Researcher (PI) Mangala Srinivas
Host Institution (HI) STICHTING KATHOLIEKE UNIVERSITEIT
Call Details Starting Grant (StG), LS7, ERC-2013-StG
Summary The success of modern medical treatments such as cellular therapy and targeted treatments requires appropriate tools for in vivo monitoring. Imaging modalities, such as magnetic resonance imaging (MRI), single photon emission computed tomography (SPECT) and positron emission tomography (PET) are key candidates due to their noninvasive nature. However, these imaging techniques are extremely expensive and can involve radiation, both of which hinder their longitudinal and repetitive use.
Ultrasound has so far been unsuitable due to the absence of a label to differentiate regions of interest from tissue background, the main problem being that current ultrasound contrast agents (CAs) have active lifetimes in the order of minutes. The CoNQUeST platform (Clinical Nanoparticles for Quantitative Ultrasound with high STability) proposed here is an entirely new type of ultrasound CA that is extremely stable (lifetime of a year) and is not affected by insonation. This mechanism of contrast generation appears completely novel: The polymeric particles are under 200nm in diameter and must contain a soluble metal (M.Srinivas et al., patent pending, filed 09/2012). Based on the current state of the art, these particles are too small and do not contain the requisite gaseous component for ultrasound contrast.
CoNQUeST particles are applicable to longitudinal and repeated imaging, as is necessary for cell tracking, due to their stability. Furthermore, these particles can be chemically bound to targeting agents, dyes and drugs, and are suitable for multimodal imaging, including MRI (both 1H and 19F), fluorescence and SPECT. Finally, the CoNQUeST agents are suitable for clinical use.
I propose the application of the CoNQUeST agents to a clinical trial for tracking dendritic cell therapy in melanoma patients, longitudinal theranostic imaging in preclinical models and thorough characterisation of this novel mechanism of ultrasound contrast generation.

Project Control of the Structure of Light at the Nanoscale
Researcher (PI) Laurens Kuipers
Host Institution (HI) TECHNISCHE UNIVERSITEIT DELFT
Call Details Advanced Grant (AdG), PE3, ERC-2013-ADG
Summary In the last decade, the fields of nanoplasmonics and photonic crystals have opened up the nanoscale for optical control. Both the flow and emission of light can be controlled at these small length scales, giving rise to new science and applications. Interestingly, freely propagating light beams can already contain nanoscale features, i.e. optical singularities. Little is known about this nanoscale structure of light.
I propose to (1) reveal the structure of light at the nanoscale and its interaction with geometrical structures or other light structures; and (2) achieve full spatio-temporal control of the nanoscale structure of light. Crucial to achieving these goals are technological innovations, which will be crosscutting objectives. These include the first nonlinear vectorial scanning near-field microscope and novel near-field probes allowing access to new combinations of vector fields.
This next step in the field of nano-optics is possible due to recent breakthroughs in the control and visualization of light at the nanoscale obtained in my group. I will combine newly acquired access to the vectorial nature of light with its active control to investigate how (deep-) subwavelength structures of light of different frequencies affect each other when coupled through a nonlinear interaction in a nanostructured material. In parallel I will focus on optical singularities. Because of their extreme size, small changes in their position will lead to huge effects in the local light fields, opening up potential for all-optical and therefore ultrafast control.
The research will lead to innovations in the visualization and control of light at the nanoscale, access to the magnetic component of light, nanoscale nonlinear optics and coherent control of light fields. The knowledge gain will be crucial for applications like ultrasensitive biosensors based on superchiral light, ultrafast magneto-optics and nanoscale quantum optics.

Project A double tilt cryoholder for ultra high resolution transmission electron microscopy at low temperatures
Researcher (PI) Henny ZANDBERGEN
Host Institution (HI) TECHNISCHE UNIVERSITEIT DELFT
Call Details Proof of Concept (PoC), PC1, ERC-2012-PoC
Summary The transmission electron microscope (TEM) is an essential instrument facilitating studies of the nanoscale material structure at sub-1Å resolution for R&D in the area of materials science, nanoscience and nanotechnology. In order to access the highly relevant temperature range between 77 K and room temperature, special specimen cryoholders need to be used that allow for a double tilt of the specimen under study. However, it is impossible to make images with sub-1Å resolution with the existing commercial double-tilt cryoholders. This is due to effects of thermal gradient-induced drift and mechanical vibrations. As part of my ERC Advanced Grant I have pioneered single-tilt cryoholders with electrical feedthroughs that largely overcome these problems, resulting in sub-1Å high resolution TEM at ~100 K in at least 15% of the images that are recorded. With this proposal, I wish to take these advances towards a proof of concept for a double-tilt cryoholder that allows sub-1Å high-resolution TEM in at least 80% of the recordings at any temperature between 77 K and 300 K and represents a user-friendly standard technique with commercial potential. I plan to make these holders available to researchers at similar price levels of currently available holders. Based on my acknowledged track record in developing microscopy innovations, I have drafted a plan to prototype this invention. I will seek an industrial partner to perform a design cycle for real production, and next produce the holders.

Project Cooperation and competition in vertical relations: the business strategies and industry oversight of supply agreements and buying patterns

Call Details Advanced Grant (AdG), SH1, ERC-2013-ADG
Summary "The application proposes to revisit the economics of cooperation and competition in industry vertical chains and develop new tools for industrial organization (IO). Modern IO theory treats firms as unitary, profit-maximizing entities, characterized by well-identified perimeters of activity, and clearly identified either as competitors or as complementors. Yet in practice:
- Industry structures are increasingly complex: Firms distribute for example their activities among partners across the globe, and moved to multiple, interlocking relationships.
- Firms competing for customers or suppliers are also cooperating in other dimensions, e.g., by setting-up common platforms, or by adopting joint common rules within which to compete.
- Supplier -customer relations often involve transaction costs other than pure search costs: adoption costs, learning or shopping costs, or expensive strategies to protect sensitive information.
Understanding the interplay between competition and cooperation is key to designing business strategies, but it has also implications for industry oversight: When should cooperation among competitors be limited or encouraged? Over which dimensions? This application proposes to cover three topics:
1. Allocation of tasks and the choice of partners.
2. Multilateral interlocking relations.
3. Cooperation and competition.
4. Transaction costs, buying patterns and business strategies
While the project falls primarily in the field of applied theory, some of the developments require new tools and interaction with game theorists. Furthermore, empirical validation will require the use of structural econometric modelling (based in particular on consumer panel data) and laboratory experiments. The project has also an interdisciplinary flavour and will benefit from work of and interactions with legal scholars and marketing experts."

Host Institution (HI) UNIVERSITEIT UTRECHT

Summary Societies in past and present are regularly confronted with major hazards, which sometimes have disastrous effects. Some societies are successful in preventing these effects and buffering threats, or they recover quickly, while others prove highly vulnerable. Why is this?
Increasingly it is clear that disasters are not merely natural events, and also that wealth and technology alone are not adequate to prevent them. Rather, hazards and disasters are social occurrences as well, and they form a tough test for the organizational capacities of a society, both in mitigation and recovery. This project targets a main element of this capacity, namely: the way societies have organized the exchange, allocation and use of resources. It aims to explain why some societies do well in preventing or remedying disasters through these institutional arrangements and others not.
In order to do so, this project analyses four key variables: the mix of coordination systems available within that society, its degree of autarky, economic equity and political equality. The recent literature on historical and present-day disasters suggests these factors as possible causes of success or failure of institutional arrangements in their confrontation with hazards, but their discussion remains largely descriptive and they have never been systematically analyzed.
This research project offers such a systematic investigation, using rural societies in Western Europe in the period 1300-1800 - with their variety of socio-economic characteristics - as a testing ground. The historical perspective enables us to compare widely differing cases, also over the long run, and to test for the variables chosen, in order to isolate the determining factors in the resilience of different societies. By using the opportunities offered by history in this way, we will increase our insight into the relative performance of societies and gain a better understanding of a critical determinant of human wellbeing.

Summary "The physics of complex quantum systems with controllable interactions is emerging as a fundamental topic for a broad community, providing an opportunity to test theories of strongly correlated quantum many-body systems and opening interesting applications such as quantum simulators. Recently, in solid-state structures with effective photon-photon interactions the rich physics of quantum fluids of light has been explored, albeit not yet in the regime of strong photonic correlations. Exciting advances in cavity Quantum Electro-Dynamics (QED) and superconducting circuit QED make strong photon-photon interactions now accessible. A growing interest is focusing on lattices of coupled resonators, implementing Hubbard-like Hamiltonians for photons injected by pump driving fields. Similarly to electronic systems, the physics of large two-dimensional (2D) photonic lattices is a fundamental theoretical challenge in the regime of strong correlations. CORPHO has the ambition to develop novel scalable theoretical methods for 2D lattices of cavities, including spatially inhomogeneous driving and dissipation. The proposed methods are based on a hybrid strategy combining cluster mean-field theory and Wave Function Monte Carlo on a physical ‘Corner’ of the Hilbert space in order to calculate the steady-state density matrix and the properties of the non-equilibrium phases. We will study 2D lattices with complex unit cells and ‘fractional’ driving (only a fraction of the sites is pumped), a configuration that, according to recent preliminary studies, is expected to dramatically enhance and enrich quantum correlations. We will also investigate the interplay between driving and geometric frustration in 2D lattices with polarization-dependent interactions. Finally, the quantum control of strongly correlated photonic systems will be explored, including quantum feedback processes, cooling of thermal fluctuations and switching between multi-stable phases."

Summary "Materials with strong electronic Coulomb correlations present unique electronic properties such as exotic magnetism, charge or orbital order, or unconventional optical or transport properties, including superconductivity, thermoelectricity or metal-insulator transitions. The concerted behavior of the electrons in these ``correlated materials"" moreover leads to an extreme sensitivity to external stimuli such as changes in temperature, pressure, or external fields. This tuneability of even fundamental properties is both a harbinger for technological applications and a challenge to currently available theoretical methods: Indeed, these properties are the result of strong electron-electron interactions and subtle quantum correlations, and cannot be understood without a proper description of excited states.
The aim of the present project is to elaborate, implement and test new approaches to investigate the spectral and optical properties of correlated materials ``from first principles"", that is, without adjustable parameters. I will build on the success of state-of-the-art dynamical mean field-based electronic structure techniques, but aim at developing them into truly first-principles methods, where a full treatment of the long-range Coulomb interactions replaces the current practice of purely local Hubbard interaction parameters. My target materials are among the most interesting for modern technologies, such as transition metal oxides (with potential applications ranging from oxide electronics to battery materials) and rare earth compounds used as environmentally-responsible pigments. Establishing first-principles techniques with truly predictive power for these classes of materials will bring us closer to the final goal of tailoring correlated materials with preassigned properties."

Summary Why do we perceive objects? Visual perception starts with localized filters that subdivide the image into fragments that undergo separate analyses. Our visual system has to reconstruct the objects that surround us. It has to bind image fragments of the same object and to segregate them from other objects and the background. The standard view in psychology is that perceptual grouping is achieved by a parallel, pre-attentive process that relies on Gestalt grouping cues. My work has started to challenge this view by demonstrating that the visual cortex also implements a serial, attention-demanding algorithm for perceptual grouping. This grouping process may represent the first serial brain algorithm that can be understood at the psychological, neurophysiological and computational level. The present proposal therefore has the potential to revolutionize our view of visual cognition.
Understanding feature binding would represent a breakthrough in cognitive neuroscience. Different brain areas represent distinct visual features. How is activity in these areas integrated? We propose that perceptual grouping relies on two complementary processes, “base-grouping” and “incremental grouping”. We hypothesize that base-grouping is pre-attentive and relies on feed-forward connections from lower to higher areas that activate neurons and determine their stimulus selectivity. In contrast, we propose that incremental grouping relies on feedback and horizontal connections, which propagate enhanced neuronal activity to highlight all the features that belong to the same perceptual object. The present proposal will determine the role of attention in feature binding, the interactions between brain areas for grouping with fMRI in humans and with electrophysiology in non-human primates to reveal the algorithms for perceptual grouping as they are implemented in our brains.

These events serve as “cosmic accelerators” for ultra-high-energy particles that are beyond reach for even to most powerful terrestrial accelerators, as well as distant sources for elusive neutrinos. Explosions leave behind compact neutron stars and black hole remnants, natural laboratories to study strong gravity. Acting as cosmic furnaces, these explosions driven the chemical evolution of the Universe Cosmic explosions trigger and inhibit star formation processes, and drive galactic evolution (“feedback”). Distances measured using supernova explosions as standard candles brought about the modern revolution in our view of the accelerating Universe, driven by enigmatic “dark energy”. Understanding the nature of cosmic explosions of all types is thus an extremely well-motivated endeavour. I have been studying cosmic explosions for over a decade, and since the earliest stages of my career, have followed an ambition to figure out the nature of cosmic explosions of all types, and to search for new types of explosions. Having already made several key discoveries, I now propose to undertake a comprehensive program to systematically tackle this problem.I review below the progress made in this field and the breakthrough results we have achieved so far, and propose to climb the next step in this scientific and technological ladder, combining new powerful surveys with comprehensive multi-wavelength and multi-disciplinary (observational and theoretical) analysis. My strategy is based on a combination of two main approaches: detailed studies of single objects which serve as keys to specific questions; and systematic studies of large samples, some that I have, for the first time, been able to assemble and analyze, and those expected from forthcoming efforts. Both approaches have already yielded tantalizing results.

Summary "Since the first laser discovery in 1960 and the first Free Electron Laser (FEL) in 1977, Linac based fourth generation light sources provide intense coherent fs pulses in the X-ray range for multidisciplinary investigations of matter. In parallel, Laser Wakefield Accelerator (LWFA) by using intense laser beams interacting with cm long plasmas can now provide high quality electron beams of very short bunches (few fs) with high peak currents (few kA). The so-called 5th generation light source aims at reducing the size and the cost of these FELs by replacing the linac by LWFA. Indeed, spontaneous emission from LWFA has already been observed, but the presently still rather large energy spread (1 %) and divergence (mrad) prevent from the FEL amplification. In 2012, two novel schemes in the transport proposed in the community, including my SOLEIL group, predict a laser gain increase by 3 or 4 orders of magnitudes. COXINEL aims at demonstrating the first lasing of an LWFA FEL and its detailed study in close interaction with future potential users. The key concept relies on an innovative electron beam longitudinal and transverse manipulation in the transport towards an undulator: a ""demixing"" chicane sorts the electrons in energy and reduces the spread from 1 % to a slice one of 0.1%, and the transverse density is maintained constant all along the undulator (supermatching). Simulations based on the performance of the 60 TW laser of the Laboratoire d’Optique Appliquée and existing undulators from SOLEIL suggest that the conditions for lasing are fulfilled. The SOLEIL environment also possesses the engineering fabrication capability for the actual realization of these theoretical ideas, with original undulators and innovative variable permanent compact magnets for the transport. COXINEL will enable to master in Europe advanced schemes scalable to shorter wavelengths and pulses, paving the way towards FEL light sources on laboratory size, for fs time resolved experiments."

Project Cracking the emotional code of music

Host Institution (HI) CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE CNRS
Call Details Starting Grant (StG), SH4, ERC-2013-StG
Summary "This project aims to ""crack"" the emotional code of music, i.e. to provide, for the first time, a precise characterization of what type of music signal is able to activate one emotion or another. Research into this problem so far has been mainly correlating indistinct emotional reactions to uncontrolled musical stimuli, with much technical sophistication but to little avail. Project CREAM builds on the PI's unique bi-disciplinary career spanning both computer science and cognitive neuroscience, to propose a radically novel approach: instead of using audio signal processing to simply observe musical stimuli a posteriori, we will harvest a series of recent developments in the field to build powerful new tools of experimental control, able to engineer musical stimuli that can activate specific emotional pathways (e.g. music manipulated to sound like expressive speech, or to sound like survival-relevant environmental sounds).
By combining this creative use of new technologies with a well-concerted mix of methods from experimental psychology and cognitive neuroscience (incl. psychoacoustics, fNIRS brain imaging, EEG/ERP paradigms, intercultural studies, infant studies), project CREAM will yield the first functional description of the neural and cognitive processes involved in the induction of emotions by music, and establish new avenues for interdisciplinary research between the life sciences and the information sciences.
But most spectacularly, the fundamental breakthroughs brought by project CREAM will unlatch the therapeutic potential of musical emotions. Music will become a cognitive technology, with algorithms able to ""engineer"" it to mobilize one neuronal pathway or another, non-intrusively and non-pharmacologically. Within the proposed 5-year plan, support from the ERC will allow to implement a series of high-impact clinical studies with are direct applications of our findings, e.g. for the linguistic rehabilitation of aphasic stroke victims."

Summary "CREATIV explores how the concept of co-adaptation can revolutionize the design and use of interactive software. Co-adaptation is the
parallel phenomenon in which users both adapt their behavior to the system’s constraints, learning its power and idiosyncrasies, and
appropriate the system for their own needs, often using it in ways unintended by the system designer.
A key insight in designing for co-adaptation is that we can encapsulate interactions and treat them as first class objects, called interaction
instruments This lets us focus on the specific characteristics of how human users express their intentions, both learning from and
controlling the system. By making instruments co-adaptive, we can radically change how people use interactive systems, providing
incrementally learnable paths that offer users greater expressive power and mastery of their technology.
The project offers theoretical, technical and empirical contributions. CREATIV will develop a novel architecture and generative principles for
creating co-adaptive instruments. The multi-disciplinary design team includes computer scientists, social scientists and designers as well
as ‘extreme users’, creative professionals who push the limits of their technology. Using participatory design techniques, we will articulate
the design space for co-adaptive instruments and build a series of prototypes. Evaluation activities include qualitative and quantitative
studies, in the lab and in the field, to test hypotheses and assess the success of the prototypes.
The initial goal of the CREATIV project is to fundamentally improve the learning and expressive capabilities of advanced users of creative
software, offering significantly enhanced methods for expressing and exploring their ideas. The ultimate goal is to radically transform
interactive systems for everyone by creating a powerful and flexible partnership between human users and interactive technology."

Summary Many companies have already started the migration to the Cloud and many individuals share their personal informations on social networks. Unfortunately, in the current access mode, the provider first authenticates the client, and grants him access, or not, according to his rights in the access-control list. Therefore, the provider itself not only has total access to the data, but also knows which data are accessed, by whom, and how: privacy, which includes secrecy of data (confidentiality), identities (anonymity), and requests (obliviousness), should be enforced.
The industry of the Cloud introduces a new implicit trust requirement: nobody has any idea at all of where and how his data are stored and manipulated, but everybody should blindly trust the providers. Privacy-compliant procedures cannot be left to the responsibility of the provider: however strong the trustfulness of the provider may be, any system or human vulnerability can be exploited against privacy. This presents too huge a threat to tolerate. The distribution of the data and the secrecy of the actions must be given back to the users. It requires promoting privacy as a global security notion.
A new generation of secure multi-party computation protocols is required to protect everybody in an appropriate way, with privacy and efficiency: interactive protocols will be the core approach to provide privacy in practical systems.
Privacy for the Cloud will have a huge societal impact since it will revolutionize the trust model: users will be able to make safe use of outsourced storage, namely for personal, financial and medical data, without having to worry about failures or attacks of the server. It will also have a strong economic impact, conferring a competitive advantage on Cloud providers implementing these tools.

Project Crystal Engineering of Metal Organic Frameworks for application in Mixed Matrix Membranes
Researcher (PI) Jorge Gascon Sabate
Host Institution (HI) TECHNISCHE UNIVERSITEIT DELFT
Call Details Starting Grant (StG), PE8, ERC-2013-StG
Summary With this proposal, I seek to develop the gas separating membranes of the future. The overall aim is to produce composite membranes comprising engineered Metal Organic Framework (MOF) particles and polymers in the form of Mixed Matrix Membranes (MMMs). By applying these new membranes, energetically more efficient separations will be possible.
Despite the superior performance of membranes only based on crystalline materials like zeolites or MOFs, polymeric membranes rule the commercial scene thanks to their easy processing, high reproducibility and mechanical strength. However, the existing polymeric membrane materials are not optimal: improvements in permeability are always at the expense of selectivity and vice versa, while plasticization threatens their application at high pressures. This research aims at utilizing the best of both fields by combining the high selectivity of MOFs with the easy processing of polymers in the form of Mixed Matrix Membranes.
The main barrier to achieve this goal is the optimization of the MOF-polymer interaction and mass transport through the composite. This is very challenging because chemical compatibility, particle morphology and filler dispersion play a key role. Innovatively the project will be the first systematic study into this multi-scale phenomenon with investigations at all relevant interactions, including MOF particle tuning targeting the application in MMMs.
A thorough study on the synthesis of the selected MOF structures and on the performance of the composites will allow engineering MOFs at the molecular and particle levels, resulting in higher selectivity and faster transport. The use of flexible MOF structures will not only allow a better membrane processing but will also reduce polymer plasticization.
This research will deliver a new generation of mixed matrix membranes, outperforming the state of the art polymeric membranes.

Host Institution (HI) THE HEBREW UNIVERSITY OF JERUSALEM
Call Details Starting Grant (StG), LS7, ERC-2013-StG
Summary The major causes of death in the Western world are cardiovascular diseases and cancer. More accurate detection of these diseases will improve clinical outcomes. Thus, we will develop unique X-ray contrast reagents for use in spectral computerized tomography (CT) that bind active proteases to reveal the exact location and stage of cancer and atherosclerosis.
Activity-based probes (ABPs) are small molecules that covalently bind to active proteases. Based on our success in developing optical ABPs for non-invasive optical detection of cancer and atherosclerosis, we will focus on two novel types of reagents: (1) ABPs conjugated to the various contrast elements that can be visualized by x-rays. (2) “smart probes” conjugated to different contrast reagents on each side of the molecule to overcome clearance limitations. Protease found in diseased tissue will selectively bind and remove a part of the molecule, changing the physical properties of the bound probe. Thus, different signals from bound and unbound probes could be detected by photon counting spectral CT scanners.
Our initial target, cysteine cathepsin proteases, are overexpressed and activated in cancer and arthrosclerosis. The level of active cathepsins correlates with progression of both diseases, thereby serving as a promising biomarker for these pathologies. The “smart probes” are an innovative type of spectral CT agent that will enable high-resolution rapid imaging in humans before probe clearance.
Our probes increase imaging sensitivity since the contrast element remains at the desired site. Moreover, the levels of active cathepsins will reveal critical information regarding disease progression, yielding more accurate diagnoses and improved personalized treatment. For example, these reagents can distinguish between a vulnerable and stable atherosclerotic plaque. Thus, our novel probes will directly reduce cancer and cardiovascular disease mortality by enabling earlier and more accurate disease detection.

Summary Bacteria replicating within host cells either multiply in membrane-bound compartment or escape into the host cytosol. The host cytosol has long been considered as a safe haven for bacteria. However, the host cytosol is armed with an array of innate immune receptors detecting cytosolic invasion. Furthermore, the macrophage cytosol displays a bacteriolytic activity, which is inducible by IFN. Surprisingly, the molecular mechanisms of this innate immune effector response are still largely uncharacterized. A ubiquitously expressed antimicrobial peptide, ubiquicidin has been described in the macrophage cytosol. Its relevance, its connection with macrophage-specific bacteriolytic activity and with IFN, remain to be deciphered. While cytosol-adapted bacteria are largely resistant to the bactericidal activity of the macrophage, lysis of a single bacterium triggers activation of the Aim2 inflammasome. Cytosolic bacteriolysis is thus key to orchestrate inflammasome-mediated innate immune responses. We propose here to characterize the bacteriolytic effector mechanisms, the regulation of this response and of the Aim2 inflammasome by IFN in infected macrophages. We will use two complementary bacterial models: F. tularensis, a cytosol-adapted bacterium and S. typhimurium sifA mutant, a bacterium lysed in the macrophage cytosol. We will develop three synergistic approaches:
i) the generation of novel tools to monitor cytosolic bacteriolysis
ii) hypothesis-driven investigations on the antimicrobial activity of the macrophage cytosol focusing on ubiquicidin to uncover the mechanisms of processing and targeting of this antimicrobial peptide
iii) screening of IFN-inducible genes to identify novel players involved in the cytosolic bacteriolytic activity and in inflammasome regulation.
We believe this project should reveal the innate immune effector mechanisms of the macrophage cytosol i.e. how the macrophage kills cytosolic bacteria and orchestrates further immune responses.

Summary "Frontier research in statistical mechanics and soft condensed matter focuses on systems of ever-increasing complexity. Among these are systems where microscopic dynamics are not controlled by thermal fluctuations, either because the sources of the fluctuations have not a thermal origin, or because “microscopic” sources of fluctuations are altogether absent. Practical applications comprise everyday products such as paints or foodstuff which are soft solids composed of dense suspensions of particles that are too large for thermal fluctuations to play any role. Non-Brownian “active” matter, obtained when particles internally produce motion, represents another growing field with applications in biophysics and soft matter. Because these systems all evolve far from equilibrium, there exists no general framework to tackle these problems theoretically from a fundamental perspective. I will develop a radically new approach to lay the foundations of a detailed theoretical understanding of the physics of a broad but coherent class of materials evolving far from equilibrium. To go beyond phenomenology, I will carry theoretical research to elucidate the physics of particle systems that are simultaneously Dense, Disordered, Driven and Dissipative—D4PARTICLES. By combining numerical analysis of model systems to fully microscopic statistical mechanics analysis, my overall aim is to discover the general principles governing the physics of athermal particle systems far from equilibrium and to reach a complete theoretical understanding and obtain predictive tools regarding the phase behavior, structure and dynamics of D4PARTICLES. Reaching a new level of theoretical understanding of a broad range of materials will impact fundamental research by opening up statistical physics to a whole new class of complex systems and should foster experimental activity towards design and quantitative characterization of large class of disordered solids and soft materials."

Summary "In order to improve the strength of a glass part (flat display, window, lens, fiber, etc.), most investigations so far were devoted to thermal and chemical surface treatments aimed at generating compressive stresses at the surface. The DAMREG project focuses on the incidence of the glass composition and atomic network structure on the mechanical properties, and specifically on the cracking and fracture behavior, and is based on the experience and expertise of the PI on the structure-property relationships in glass science. This project proposes to address the fundamental issue of glass brittleness in a new paradigm of thinking, questioning the usefulness of the standard fracture toughness parameter, with emphasis on the surface flaw generation process (multiscale approach), and aims at determining novel routes to improve the mechanical performance of glass further promoting innovative applications. DAMREG involves revisiting the fundamental fracture mechanics concepts, the preparation of novel glass compositions, and nanoscale physico-chemical and mechanical characterization. So far most glass fracture studies focused on the crack tip behavior, and were limited to vitreous silica. A crack acts as a lever arm for the stress so that the singular stress at the tip is proportional to the crack length and inversely proportional to the square-root of the tip radius (provided this has a meaning). Since a crack can hardly be cured or shielded at ambient, the presence of a sharp crack is already detrimental. On the contrary to this approach, DAMREG is aimed at understanding the crack initiation process, and the main objective is to define some roadmap to design glasses (composition, thermo-mechanical treatments etc.) with better damage (initiation) resistance."
Summary
"In order to improve the strength of a glass part (flat display, window, lens, fiber, etc.), most investigations so far were devoted to thermal and chemical surface treatments aimed at generating compressive stresses at the surface. The DAMREG project focuses on the incidence of the glass composition and atomic network structure on the mechanical properties, and specifically on the cracking and fracture behavior, and is based on the experience and expertise of the PI on the structure-property relationships in glass science. This project proposes to address the fundamental issue of glass brittleness in a new paradigm of thinking, questioning the usefulness of the standard fracture toughness parameter, with emphasis on the surface flaw generation process (multiscale approach), and aims at determining novel routes to improve the mechanical performance of glass further promoting innovative applications. DAMREG involves revisiting the fundamental fracture mechanics concepts, the preparation of novel glass compositions, and nanoscale physico-chemical and mechanical characterization. So far most glass fracture studies focused on the crack tip behavior, and were limited to vitreous silica.

Project acronym DARK
Project Dark matter of the human transcriptome: Functional study of the antisense Long Noncoding RNAs and Molecular Mechanisms of Action
Researcher (PI) Antonin Morillon
Host Institution (HI) INSTITUT CURIE
Call Details Consolidator Grant (CoG), LS2, ERC-2013-CoG
Summary 98% of the human genome is non-protein coding raising the question of the role of the dark matter of the genome. It is now admitted that pervasive transcription generates thousands of noncoding transcripts that regulate gene expression and have broad impacts on development and disease. Among the long non coding (lnc)RNAs, antisense transcripts have been poorly studied despite their putative regulatory importance. Several functional examples include X-chromosome inactivation, maintenance of pluripotency and transcriptional regulation. However, no systematic study has yet addressed the comprehensive functional description of human antisense ncRNA, mainly because of technological issues and their low abundance. Indeed, in budding yeast S. cerevisiae, our group showed the existence of an entire class of antisense regulatory lncRNA extremely sensitive to RNA decay pathways, impinging their study so far. The roles for yeast antisense lncRNAs in shaping the epigenome raises important questions: What are the molecular and biochemical mechanisms by which antisense lncRNAs carry out their functions and are they functionally conserved in human cells? We propose that the dark side of the non-coding genome is another layer of gene regulation complexity that needs to be deciphered.
With this proposal, we aim to draw the first exhaustive catalog of human antisense lncRNA in various cell types and tissues using up to date High throughput technologies and bioinformatics pipelines. Second, we propose to determine the functional role of antisense lncRNA on genome expression and stability in the context of cellular stress and cancer. We anticipate that powerful and modern genetic tools such DNA-mediated gene inactivation (ASO) and TALEN approaches will allow precise antisense genes manipulation never achieved so far. Our project is strongly supported by preliminary data indicating an unexpected large number of hidden antisense lncRNA in human cells controlled by RNA decay pathways.
