Summary The numerical simulation of complex compressible flow problem is still a challenge nowaday even for simple models. In our opinion, the most important hard points that need currently to be tackled and solved is how to obtain stable, scalable, very accurate, easy to code and to maintain schemes on complex geometries. The method should easily handle mesh refinement, even near the boundary where the most interesting engineering quantities have to be evaluated. Unsteady uncertainties in the model, for example in the geometry or the boundary conditions should represented efficiently.This proposal goal is to design, develop and evaluate solutions to each of the above problems. Our work program will lead to significant breakthroughs for flow simulations. More specifically, we propose to work on 3 connected problems: 1-A class of very high order numerical schemes able to easily deal with the geometry of boundaries and still can solve steep problems. The geometry is generally defined by CAD tools. The output is used to generate a mesh which is then used by the scheme. Hence, any mesh refinement process is disconnected from the CAD, a situation that prevents the spread of mesh adaptation techniques in industry! 2-A class of very high order numerical schemes which can utilize possibly solution dependant basis functions in order to lower the number of degrees of freedom, for example to compute accurately boundary layers with low resolutions. 3-A general non intrusive technique for handling uncertainties in order to deal with irregular probability density functions (pdf) and also to handle pdf that may evolve in time, for example thanks to an optimisation loop. The curse of dimensionality will be dealt thanks Harten's multiresolution method combined with sparse grid methods. Currently, and up to our knowledge, no scheme has each of these properties. This research program will have an impact on numerical schemes and industrial applications.

Project Origins and spread of agriculture in the south-western Mediterranean region
Researcher (PI) Maria Leonor Peña Chocarro
Host Institution (HI) AGENCIA ESTATAL CONSEJO SUPERIOR DEINVESTIGACIONES CIENTIFICAS
Call Details Advanced Grant (AdG), SH6, ERC-2008-AdG
Summary This project focuses on one of the most fascinating events of the long history of the human species: the origins and spread of agriculture. Research over the past 40 years has provided an invaluable dataset on crop domestication and the spread of agriculture into Europe. However, despite the enormous advances in research there are important areas that remain almost unexplored, some of immense interest. This is the case of the western Mediterranean region from where our knowledge is still limited (Iberian Peninsula) or almost inexistent (northern Morocco). The last few years have witnessed a considerable increase in archaeobotany and the effort of a group of Spanish researchers working together in different aspects of agriculture has started to produce the first results. My proposal will approach the study of the arrival of agriculture to the western Mediterranean by exploring different interrelated research areas. The project involves the
application of different techniques (analysis of charred plant remains, pollen and non-pollen microfossils, phytoliths, micro-wear analyses, isotopes, soil micromorphology, genetics, and ethnoarchaeology) which will help to define the emergence and spread of agriculture in the area, its likely place of origin, its main technological attributes as well as the range crop husbandry practices carried out. The interaction between the different approaches and the methodologies involved will allow achieving a greater understanding of the type of agriculture that characterized the first farming communities in the most south-western part of Europe.

Project The influence of Aryl hydrocarbon receptor ligands on protective and pathological immune responses
Researcher (PI) Brigitta Stockinger
Host Institution (HI) MEDICAL RESEARCH COUNCIL
Call Details Advanced Grant (AdG), LS6, ERC-2008-AdG
Summary The Aryl hydrocarbon receptor is an evolutionary conserved widely expressed transcription factor that mediates the toxicity of a substantial variety of exogenous toxins, but is also stimulated by endogenous physiological ligands. While it is known that this receptor mediates the toxicity of dioxin, this is unlikely to be its physiological function. We have recently identified selective expression of AhR in the Th17 subset of effector CD4 T cells. Ligation of AhR by a candidate endogenous ligand (FICZ) which is a UV metabolite of tryptophan causes expansion of Th17 cells and the induction of IL-22 production. As a consequence, AhR ligation will exacerbate autoimmune diseases such as experimental autoimmune encephalomyelitis. Little is known so far about the impact of AhR ligands on IL-17/IL-22 mediated immune defense functions. IL-22 is considered a pro-inflammatory Th17 cytokine, which is involved in the etiology of psoriasis, but it has also been shown to be a survival factor for epithelial cells. AhR is polymorphic and defined as high or low affinity receptor for dioxin leading to the classification of high and low responder mouse strains based on defined mutations. In humans similar polymorphisms exist and although on the whole human AhR is thought to be of low affinity in humans, there are identified mutations that confer high responder status. No correlations have been made with Th17 mediated immune responses in mice and humans. This study aims to investigate the role of AhR ligands and polymorphisms in autoimmunity as well as protective immune responses using both mouse models and human samples from normal controls as well as psoriasis patients.

Project Genomics and effectoromics to understand defence suppression and disease resistance in Arabidopsis-Albugo candida interactions
Researcher (PI) Jonathan Jones
Host Institution (HI) THE SAINSBURY LABORATORY
Call Details Advanced Grant (AdG), LS6, ERC-2008-AdG
Summary This project focuses on two questions about host/parasite interactions: how do biotrophic plant pathogens suppress host defence? and, what is the basis for pathogen specialization on specific host species? A broadly accepted model explains resistance and susceptibility to plant pathogens. First, pathogens make conserved molecules ( PAMPS ) such as flagellin, that plants detect via cell surface receptors, leading to PAMP-Triggered Immunity (PTI). Second, pathogens make effectors that suppress PTI. Third, plants carry 100s of Resistance (R) genes that detect an effector, and activate Effector-Triggered Immunity (ETI). One effector is sufficient to trigger resistance. Albugo candida (Ac) (white rust) strongly suppresses host defence; Ac-infected Arabidopsis are susceptible to pathogen races to which they are otherwise resistant. Ac is an oomycete, not a fungus. Arabidopsis is resistant to races of Ac that infect brassicas. The proposed project involves three programs. First ( genomics, transcriptomics and bioinformatics ), we will use next-generation sequencing (NGS) methods (Solexa and GS-Flex), and novel transcriptomics methods to define the genome sequence and effector set of three Ac strains, as well as carrying out >40- deep resequencing of 7 additional Ac strains. Second, ( effectoromics ), we will carry out functional assays using Effector Detector Vectors (Sohn Plant Cell 19:4077 [2007]), with the set of Ac effectors, screening for enhanced virulence, for suppression of defence, for effectors that are recognized by R genes in disease resistant Arabidopsis and for host effector targets. Third, ( resistance diversity ), we will characterize Arabidopsis germplasm for R genes to Ac, both for recognition of Arabidopsis strains of Ac, and for recognition in Arabidopsis of effectors from Ac strains that infect brassica. This proposal focuses on Ac, but will establish methods that could discover new R genes in non-hosts against many plant diseases.

Project Metabolic control by the TGF-² superfamily receptor ALK7: A novel regulator of insulin secretion, fat accumulation and energy balance
Researcher (PI) Carlos Ibanez
Host Institution (HI) KAROLINSKA INSTITUTET
Call Details Advanced Grant (AdG), LS4, ERC-2008-AdG
Summary The aim of this proposal is to understand a novel regulatory signaling network controlling insulin secretion, fat accumulation and energy balance centered around selected components of the TGF-² signaling system, including Activins A and B, GDF-3 and their receptors ALK7 and ALK4. Recent results from my laboratory indicate that these molecules are part of paracrine signaling networks that control important functions in pancreatic islets and adipose tissue through feedback inhibition and feed-forward regulation. These discoveries have open up a new research area with important implications for the understanding of metabolic networks and the treatment of human metabolic syndromes, such as diabetes and obesity.
To drive progress in this new research area beyond the state-of-the-art it is proposed to: i) Elucidate the molecular mechanisms by which Activins regulate Ca2+ influx and insulin secretion in pancreatic ²-cells; ii) Elucidate the molecular mechanisms underlying the effects of GDF-3 on adipocyte metabolism, turnover and fat accumulation; iii) Investigate the interplay between insulin levels and fat deposition in the development of insulin resistance using mutant mice lacking Activin B and GDF-3; iv) Investigate tissue-specific contributions of ALK7 and ALK4 signaling to metabolic control by generating and characterizing conditional mutant mice; v) Investigate the effects of specific and reversible inactivation of ALK7 and ALK4 on metabolic regulation using a novel chemical-genetic approach based on analog-sensitive alleles.
This is research of a high-gain/high-risk nature. It is posed to open unique opportunities for further exploration of complex metabolic networks. The development of drugs capable of enhancing insulin secretion, limiting fat accumulation and ameliorating diet-induced obesity by targeting components of the ALK7 signaling network will find a strong rationale in the results of the proposed work.

Project Attosecond Control of Light and Matter
Researcher (PI) Anne L'huillier
Host Institution (HI) LUNDS UNIVERSITET
Call Details Advanced Grant (AdG), PE2, ERC-2008-AdG
Summary Attosecond light pulses are generated when an intense laser interacts with a gas target. These pulses are not only short, enabling the study of electronic processes at their natural time scale, but also coherent. The vision of this proposal is to extend temporal coherent control concepts to a completely new regime of time and energy, combining (i) ultrashort pulses (ii) broadband excitation (iii) high photon energy, allowing scientists to reach not only valence but also inner shells in atoms and molecules, and, when needed, (iv) high spatial resolution. We want to explore how elementary electronic processes in atoms, molecules and more complex systems can be controlled by using well designed sequences of attosecond pulses. The research project proposed is organized into four parts: 1. Attosecond control of light leading to controlled sequences of attosecond pulses We will develop techniques to generate sequences of attosecond pulses with a variable number of pulses and controlled carrier-envelope-phase variation between consecutive pulses. 2. Attosecond control of electronic processes in atoms and molecules We will investigate the dynamics and coherence of phenomena induced by attosecond excitation of electron wave packets in various systems and we will explore how they can be controlled by a controlled sequence of ultrashort pulses. 3. Intense attosecond sources to reach the nonlinear regime We will optimize attosecond light sources in a systematic way, including amplification of the radiation by injecting a free electron laser. This will open up the possibility to develop nonlinear measurement and control schemes. 4. Attosecond control in more complex systems, including high spatial resolution We will develop ultrafast microscopy techniques, in order to obtain meaningful temporal information in surface and solid state physics. Two directions will be explored, digital in line microscopic holography and photoemission electron microscopy.

Host Institution (HI) KUNGLIGA TEKNISKA HOEGSKOLAN
Call Details Advanced Grant (AdG), PE5, ERC-2008-AdG
Summary Most of the technological materials have been developed by very expensive and cumbersome trial and error methods. On the other hand, computer based theoretical design of advanced materials is an area where rapid and extensive developments are taking place. Within my group new theoretical tools have now been established which are extremely well suited to the study of complex materials. In this approach basic quantum mechanical theories are used to describe fundamental properties of alloys and compounds. The utilization of such calculations to investigate possible optimizations of certain key properties represents a major departure from the traditional design philosophy. The purpose of my project is to build up a new competence in the field of computer-aided simulations of advanced materials. The main goal will be to achieve a deep understanding of the behaviour of complex metallic systems under equilibrium and non-equilibrium conditions at the atomic level by studying their electronic, magnetic and atomic structure using the most modern and advanced computational methods. This will enable us to establish a set of materials parameters and composition-structure-property relations that are needed for materials optimization.
The research will be focused on fundamental technological properties related to defects in advanced metallic alloys (high-performance steels, superalloys, and refractory, energy related and geochemical materials) and alloy phases (solid solutions, intermetallic compounds), which will be studied by means of parameter free atomistic simulations combined with continuum modelling. As a first example, we will study the Fe-Cr system, which is of great interest to industry as well as in connection to nuclear waste. The Fe-Cr-Ni system will form another large group of materials under the aegis of this project. Special emphasis will also be placed on those Fe-alloys which exist under extreme conditions and are possible candidates for the Earth core.

Host Institution (HI) THE UNIVERSITY OF EXETER
Call Details Advanced Grant (AdG), SH2, ERC-2008-AdG
Summary This four-year interdisciplinary project addresses the question what has been learned through the use of better regulation ? Better regulation is a flagship policy on the Lisbon agenda for growth and jobs. Its aims are to provide new governance architectures for law-making, to increase the competitiveness of the regulatory environment, and to secure wide social legitimacy for multi-level systems of rules. Whilst most of the research has looked at how better regulation is changing, this project will produce findings on what has changed because of better regulation. Theoretically, the project will use (and significantly improve on) theories of policy learning. Empirically, it will cover Denmark, Italy, the Netherlands, Poland, the UK and the EU including multi-level analysis and analysis by sector of regulation. Methodologically, the project will draw on comparative analysis of types of learning, experiments with regulatory policy-makers in six countries and the European Commission, large-n analysis of impact assessments, backward-mapping of legislation (to appraise the role played by better regulation in the formulation or laws in the UK and the EU), meta-analysis of case-studies and co-production of knowledge with better regulation officers. Dissemination will target both stakeholders (i.e., policy officers, civil society organizations, and business federations) and academic conferences in political science, law, and risk analysis, with a major research monograph to be completed in year 4 and a final interdisciplinary conference.

Summary This proposal targets the emerging frontier research field of multiple-input multiple-output (MIMO) systems along with several innovative and somewhat unconventional applications of such systems. The use of arrays of transmitters and receivers will have a profound impact on future medical imaging/therapy systems, radar systems, and radio communication networks. Multiple transmitters provide a tremendous versatility and allow waveforms to be adapted temporally and spatially to environmental conditions. This is useful for individually tailored illumination of human tissue in biomedical imaging or ultrasound therapy. In radar systems, multiple transmit beams can be formed simultaneously via separate waveform designs allowing accurate target classification. In a wireless communication system, multiple communication signals can be directed to one or more users at the same time on the same frequency carrier. In addition, multiple receivers can be used in the above applications to provide increased detection performance, interference rejection, and improved estimation accuracy. The joint modelling, analysis, and design of these multidimensional transmit and receive schemes form the core of this research proposal. Ultimately, our research aims at developing the fundamental tools that will allow the design of wireless communication systems with an order-of-magnitude higher capacity at a lower cost than today; of ultrasound therapy systems maximizing delivered power while reducing treatment duration and unwanted illumination; and of distributed aperture multi-beam radars allowing more effective target location, identification, and classification. Europe has several successful industries that are active in biomedical imaging/therapy, radar systems, and wireless communications. The future success of these sectors critically depends on the ability to innovate and integrate new technology.

Summary Applied mathematics is concerned with developing models with predictive capability, and with probing those models to obtain qualitative and quantitative insight into the phenomena being modelled. Statistics is data-driven and is aimed at the development of methodologies to optimize the information derived from data. The increasing complexity of phenomena that scientists and engineers wish to model, together with our increased ability to gather, store and interrogate data, mean that the subjects of applied mathematics and statistics are increasingly required to work in conjunction. This research proposal is concerned with a research program at the interface between these two disciplines, aimed at problems in differential equations where profusion of data and the sophisticated model combine to produce the mathematical problem of obtaining information from a probability measure on function space. Applications are far-reaching and include the atmospheric sciences, geophysics, chemistry, econometrics and signal processing. The objectives of the research are: (i) to create the systematic foundations for a range of problems at the applied mathematics and statistics interface which share the common mathematical structure underpinning the range of applications described above; (ii) to exploit this common mathematical structure to design effecient algorithms to sample probability measures on function space; (iii) to apply these algorithms to attack a range of significant problems arising in molecular dynamics and in the atmospheric sciences.

Host Institution (HI) STICHTING KATHOLIEKE UNIVERSITEIT
Call Details Advanced Grant (AdG), LS8, ERC-2008-AdG
Summary For over a century it was believed that ammonium could only be oxidized by microbes in the presence of oxygen. The possibility of anaerobic ammonium oxidation (anammox) was considered impossible. However, about 10 years ago the microbes responsible for the anammox reaction were discovered in a wastewater plant. This was followed by the identification of the responsible bacteria. Recently, the widespread environmental occurrence of the anammox bacteria was demonstrated leading to the realization that anammox bacteria may play a major role in biological nitrogen cycling. The anammox bacteria are unique microbes with many unusual properties. These include the biological turn-over of hydrazine, a well known rocket fuel, the biological synthesis of ladderane lipids, and the presence of a prokaryotic organelle in the cytoplasma of anammox bacteria. The aim of this project is to obtain a fundamental understanding of the metabolism and ecological importance of the anammox bacteria. Such understanding contributes directly to our environment and economy because the anammox bacteria form a new opportunity for nitrogen removal from wastewater, cheaper, with lower carbon dioxide emissions than existing technology. Scientifically the results will contribute to the understanding how hydrazine and dinitrogen gas are made by the anammox bacteria. The research will show which gene products are responsible for the anammox reaction, and how their expression is regulated. Furthermore, the experiments proposed will show if the prokaryotic organelle in anammox bacteria is involved in energy generation. Together the environmental and metabolic data will help to understand why anammox bacteria are so successful in the biogeochemical nitrogen cycle and thus shape our planets atmosphere. The different research lines will employ state of the art microbial and molecular methods to unravel the exceptional properties of these highly unusual and important anammox bacteria.

Project microRNAs in vascular homeostasis
Researcher (PI) Stefanie Dimmeler
Host Institution (HI) JOHANN WOLFGANG GOETHE-UNIVERSITATFRANKFURT AM MAIN
Call Details Advanced Grant (AdG), LS4, ERC-2008-AdG
Summary Despite improved therapy, cardiovascular diseases remain the most prevalent diseases in the European Union and the incidence is rising due to increased obesity and ageing. The fine-tuned regulation of vascular functions is essential not only for preventing atherosclerotic diseases, but also after tissue injury, where the coordinated growth and maturation of new blood vessels provides oxygen and nutrient supply. On the other hand, excessive vessel growth or the generation of immature, leaky vessels contributes to pathological angiogenesis. Thus, the regulation of the complex processes governing vessel growth and maturation has broad impacts for several diseases ranging from tumor angiogenesis, diabetic retinopathy, to ischemic cardiovascular diseases. MicroRNAs (miRs) are small noncoding RNAs, which play a crucial role in embryonic development and tissue homeostasis. However, only limited information is available regarding the role of miRs in the vasculature. MiRs regulate gene expression by binding to the target mRNA leading either to degradation or to translational repression. Because miRs control patterns of target genes, miRs represent an attractive and promising therapeutic target to interfere with complex processes such as neovascularization and repair of ischemic tissues. Therefore, the present application aims to identify miRs in the vasculature, which regulate vessel growth and vessel remodelling and may, thus, serve as therapeutic targets in ischemic diseases. Since ageing critically impairs endothelial function, neovascularization and vascular repair, we will specifically identify miRs, which are dysregulated during ageing in endothelial cells and pro-angiogenic progenitor cells, in order to develop novel strategies to rescue age-induced impairment of neovascularization. Beyond the specific scope of the present application, the principle findings may have impact for other diseases, where deregulated vessel growth causes or accelerates disease states.

Call Details Advanced Grant (AdG), LS4, ERC-2008-AdG
Summary Our research interests lie in breaking new ground in studying mechanism-based functions of AP-1 (Fos/Jun) in vivo with the aim of obtaining a more global perspective on AP-1 in human physiology and disease/cancer. The unresolved issues regarding the AP-1 subunit composition will be tackled biochemically and genetically in various cell types including bone, liver and skin, the primary organs affected by altered AP-1 activity. I plan to utilize the knowledge gained on AP-1 functions in the mouse and transfer it to human disease. The opportunities here lie in exploiting the knowledge of AP-1 target genes and utilizing this information to interfere with pathways involved in normal physiology and disease/cancer. The past investigations revealed that the functions of AP-1 are an essential node at the crossroads between life and death in different cellular systems. I plan to further exploit our findings and concentrate on utilising better mouse models to define these connections. The emphasis will be on identifying molecular signatures and potential treatments in models for cancer, inflammatory and fibrotic diseases. Exploring genetically modified stem cell-based therapies in murine and human cells is an ongoing challenge I would like to meet in the forthcoming years at the CNIO. In addition, the mouse models will be used for mechanism-driven therapeutic strategies and these studies will be undertaken in collaboration with the Experimental Therapeutics Division and the service units such as the tumor bank. The project proposal is divided into 6 Goals (see also Figure 1): Some are a logical continuation based on previous work with completely new aspects (Goal 1-2), some focussing on in depth molecular analyses of disease models with innovative and unconventional concepts, such as for inflammation and cancer, psoriasis and fibrosis (Goal 3-5). A final section is devoted to mouse and human ES cells and their impact for regenerative medicine in bone diseases and cancer.

Project Approximation of NP-hard optimization problems

Host Institution (HI) KUNGLIGA TEKNISKA HOEGSKOLAN
Call Details Advanced Grant (AdG), PE6, ERC-2008-AdG
Summary The proposed project aims to create a center of excellence that aims at understanding the approximability of NP-hard optimization problems. In particular, for central problems like vertex cover, coloring of graphs, and various constraint satisfaction problems we want to study upper and lower bounds on how well they can be approximated in polynomial time. Many existing strong results are based on what is known as the Unique Games Conjecture (UGC) and a significant part of the project will be devoted to studying this conjecture. We expect that a major step needed to be taken in this process is to further develop the understanding of Boolean functions on the Boolean hypercube. We anticipate that the tools needed for this will come in the form of harmonic analysis which in its turn will rely on the corresponding results in the analysis of functions over the domain of real numbers.

Host Institution (HI) KUNGLIGA TEKNISKA HOEGSKOLAN
Call Details Advanced Grant (AdG), PE9, ERC-2008-AdG
Summary Magnetic fields in stars, planets, accretion discs, and galaxies are believed to be the result of a dynamo process converting kinetic energy into magnetic energy. This work focuses on the solar dynamo, but dynamos in other astrophysical systems will also be addressed. In particular, direct high-resolution three-dimensional simulations are used to understand particular aspects of the solar dynamo and ultimately to simulate the solar dynamo as a whole. Phenomenological approaches will be avoided in favor of obtaining rigorous results. A major problem is catastrophic quenching, i.e. the decline of dynamo effects in inverse proportion to the magnetic Reynolds number, which is huge. Tremendous advances have been made in the last few years since the cause of catastrophic quenching in dynamos has been understood in terms of magnetic helicity evolution. The numerical tools are now in place to allow for magnetic helicity fluxes via coronal mass ejections, thus alleviating catastrophic quenching. This work employs simulations in spherical shells, augmented by Cartesian simulations in special cases. The roles of the near-surface shear layer, the tachocline, as well as pumping in the bulk of the convection zone are to be clarified. The Pencil Code will be used for most applications. The code is third order in time and sixth order in space and is used for solving the hydromagnetic equations. It is a public domain code developed by roughly 20 scientists world wide and maintained under an a central versioning system at Nordita. Automatic nightly tests of currently 30 applications ensure the integrity of the code. It is used for a wide range of applications and may include the effects of radiation, self-gravity, dust, chemistry, variable ionization, cosmic rays, in addition to those of magnetohydrodynamics. The code with its infrastructure offers a good opportunity for individuals within a broad group of people to develop new tools that may automatically be useful to others.

Project Atmospheric nucleation: from molecular to global scale
Researcher (PI) Markku Tapio Kulmala
Host Institution (HI) HELSINGIN YLIOPISTO
Call Details Advanced Grant (AdG), PE10, ERC-2008-AdG
Summary Atmospheric aerosol particles and trace gases affect the quality of our life in many ways (e.g. health effects, changes in climate and hydrological cycle). Trace gases and atmospheric aerosols are tightly connected via physical, chemical, meteorological and biological processes occurring in the atmosphere and at the atmosphere-biosphere interface. One important phenomenon is atmospheric aerosol formation, which involves the production of nanometer-size particles by nucleation and their growth to detectable sizes. The main scientific objectives of this project are 1) to quantify the mechanisms responsible for atmospheric new particle formation and 2) to find out how important this process is for the behaviour of the global aerosol system and, ultimately, for the whole climate system. Our scientific plan is designed as a research chain that aims to advance our understanding of climate and air quality through a series of connected activities. We start from molecular simulations and laboratory measurements to understand nucleation and aerosol thermodynamic processes. We measure nanoparticles and atmospheric clusters at 15-20 sites all around the world using state of the art instrumentation and study feedbacks and interactions between climate and biosphere. With these atmospheric boundary layer studies we form a link to regional-scale processes and further to global-scale phenomena. In order to be able to simulate global climate and air quality, the most recent progress on this chain of processes must be compiled, integrated and implemented in Climate Change and Air Quality numerical models via novel parameterizations.

Call Details Advanced Grant (AdG), PE5, ERC-2008-AdG
Summary While heparin, a glacosaminoglycan (GAG) has served as an anticoagulant for more than 60 years, the structure-activity relationship of heparin and chondroitin sulfate for specific interactions with proteins are still poorly understood. It has become evident that defined lengths and sequences or patterns are responsible for binding to a particular protein and modulating its biological activity. Determination of the structure-activity relationships of heparins and chondroitins creates an opportunity to modulate processes underlying viral entry, angiogenesis, kidney diseases and diseases of the central nervous system. The isolation of pure GAGs is extremely tedious and chemical synthesis is often the only means to access defined oligosaccharides. Currently available synthetic methods for the preparation of heparins and chondroitins are time consuming and lack generality. Therefore, it is still impossible to create large collections of GAG oligosaccharides for systematic studies of GAG-protein interactions. The overall goal of the project is the development of all aspects of automated GAG synthesis, the procurement of a large collection of heparin and chondroitin oligosaccharides of 2-10 sugars in length with a linker for ready attachment to microarray surfaces and other tools. These molecular tools will be employed to study the interaction of GAGs with growth factors, chemokines and other proteins. The specific aims include: 1) Synthesis of uronic acid and galactosamine building blocks; 2) Development of a new linker for automated GAG solid phase synthesis; 3) Construction of a new automated oligosaccharide synthesizer; 4) Development of methods for the automated assembly of heparin and chondroitin sulfate oligosaccharides; 5) Synthesis of a collection of defined heparin and chondroitin sulfate oligosaccharides; 6) Construction of synthetic GAG microarrays and SPR; 7) Preparation of GAG dendrimers and quantum dots.

Project Bidirectional cortical communication interface

Host Institution (HI) EBERHARD KARLS UNIVERSITAET TUEBINGEN
Call Details Advanced Grant (AdG), PE7, ERC-2008-AdG
Summary This project aims at establishing bidirectional communication via the cortical areas of the brain. In recent years there have been extensive research efforts for establishing an efferent pathway from the brain by means of cortical recordings to allow patients suffering from amyotrophic lateral sclerosis (ALS), stroke or high spinal cord lesions to interact with their environment (Birbaumer and Cohen, 2007; Wolpaw et al., 2002). As an extension this project will investigate the possibility of an afferent pathway to the brain by means of cortical stimulation, since it is ex-pected that stimulation might help to increase the information transfer rate for the efferent path-way. To achieve this there are two possible stimulation paradigms to be investigated. The first is based on the identification of optimal brain states for communication and the active maintenance of these states by stimulation. Inspired by classical conditioning, the second stimulation paradigm seeks to support and accelerate the rehabilitation process in stroke patients, as well as the learning process needed for the efferent communication pathway in ALS patients. By development of visual cortical prostheses (Schmidt et al., 1996) it became apparent that there are several fundamental problems related to cortical stimulation, which need to be solved before it is possible to evoke well-defined neural responses by stimulation - a prerequisite of the stimulation paradigms mentioned above. To overcome these problems it is envisaged to adapt stimulus parameters based on the current background brain activity by a feedback system in real time. Leveraging prior knowledge from microstimulation studies the feasibility of this approach will be evaluated by simultaneous stimulation and recording from ECoG grids and accompanied by the development of suitable algorithms.

Summary BIOFORCE has a highly ambitious applied objective: to create transgenic cereal plants that will provide a near-complete micronutrient complement (vitamins A, C, E, folate and essential minerals Ca, Fe, Se and Zn) for malnourished people in the developing world, as well as built-in resistance to insects and parasitic weeds. This in itself represents a striking advance over current efforts to address food insecurity using applied biotechnology in the developing world. We will also address fundamental mechanistic aspects of multi-gene/pathway engineering through transcriptome and metabolome profiling. Fundamental science and applied objectives will be achieved through the application of an exciting novel technology (combinatorial genetic transformation) developed and patented by my research group. This allows the simultaneous transfer of an unlimited number of transgenes into plants followed by library-based selection of plants with appropriate genotypes and phenotypes. All transgenes integrate into one locus ensuring expression stability over multiple generations. This proposal represents a new line of research in my laboratory, founded on incremental advances in the elucidation of transgene integration mechanisms in plants over the past two and a half decades. In addition to scientific issues, BIOFORCE address challenges such as intellectual property, regulatory and biosafety issues and crucially how the fruits of our work will be taken up through philanthropic initiatives in the developing world while creating exploitable opportunities elsewhere. BIOFORCE is comprehensive and it provides a complete package that stands to make an unprecedented contribution to food security in the developing world, while at the same time generating new knowledge to streamline and simplify multiplex gene transfer and the simultaneous modification of multiple complex plant metabolic pathways

Summary During the past decades the PI has helped shape the research field of computer simulation of biomolecular systems at the atomic level. He has carried out one of the first molecular dynamics (MD) simulations of proteins, and has since then contributed many different methodological improvements and developed one of the major atomic-level force fields for simulations of proteins, carbohydrates, nucleotides and lipids. Methodology and force field have been implemented in a set of programs called GROMOS (GROningen MOlecular Simulation package), which is currently used in hundreds of academic and industrial research groups from over 50 countries on all continents. It is proposed to develop a next generation of molecular models, force fields, multi-scaling simulation methodology and software for biomolecular simulations which is at least an order of magnitude more accurate in terms of energetics, and which is 1000 times more efficient through the use of coarse-grained molecular models than the currently available software and models.

It is proposed to develop a next generation of molecular models, force fields, multi-scaling simulation methodology and software for biomolecular simulations which is at least an order of magnitude more accurate in terms of energetics, and which is 1000 times more efficient through the use of coarse-grained molecular models than the currently available software and models.

Summary Autonomous programmable computing devices made of biological molecules hold the promise of interacting with the biological environment in future biological and medical applications. Our laboratory's long-term objective is to develop a 'Doctor in a cell': molecular-sized device that can roam the body, equipped with medical knowledge. It would diagnose a disease by analyzing the data available in its biochemical environment based on the encoded medical knowledge and treat it by releasing the appropriate drug molecule in situ. This kind of device might, in the future, be delivered to all cells in a specific tissue, organ or the whole organism, and cure or kill only those cells diagnosed with a disease. Our laboratory embarked on the attempt to design and build these molecular computing devices and lay the foundation for their future biomedical applications. Several important milestones have already been accomplished towards the realization of the Doctor in a cell vision. The subject of this proposal is a construction of autonomous biomolecular computers that could be delivered into a living cell, interact with endogenous biomolecules that are known to indicate diseases, logically analyze them, make a diagnostic decision and couple it to the production of an active biomolecule capable of influencing cell fate.

Project Traces in the bones: reconstructing the lost soft anatomy of the earliest vertebrates through ultra-high resolution synchrotron scanning
Researcher (PI) Per Erik Ahlberg
Host Institution (HI) UPPSALA UNIVERSITET
Call Details Advanced Grant (AdG), LS8, ERC-2008-AdG
Summary Early vertebrate evolution involved a series of drastic structural reorganisations as new features were added and elaborated. The fossil record illuminates this evolutionary history more directly than inferences from the diversity of living forms, but the fossils usually consist only of bones whereas many of the most important and interesting changes occurred in the soft anatomy. Traditional approaches to reconstructing the musculature and other soft tissues of fossil vertebrates rely on subjective tools, like the visual identification of rough bone textures thought to indicate muscle attachments, and generally leave a lot to be desired. Here I propose a wholly novel and radically more objective approach to the identification of soft-tissue contacts, using holotomographic synchrotron CT at sub-micron resolutions to identify these contacts by the three-dimensional micro-architecture of the bone. A pilot study has already shown that such scans (performed at the ESRF synchrotron facility in Grenoble) are capable of imaging key features such as arrested growth surfaces and probable Sharpey s fibres in 380 million year old fossils. We will undertake a systematic review of the three-dimensional bone micro-architectures associated with different soft-tissue contacts in living vertebrates, and the use this as a key to reconstruct the soft-tissue contacts on fossil bones with unprecedented accuracy. This will permit us to produce far more reliable reconstructions of the soft anatomy than has hitherto been possible. Our findings will inform other areas of palaentology, particularly functional morphology, and will also be of great importance to evolutionary developmental biology.

Summary Humans interact with other people throughout their lives. This project aims to demonstrate that the complex social shaping of the human brain can be adequately tackled only by taking a leap from the conven-tional single-person neuroscience to two-person neuroscience. We will (1) develop a conceptual framework and experimental setups for two-person neuroscience, (2) apply time-sensitive methods for studies of two interacting persons, monitoring both brain and autonomic nervous activity to also cover the brain body connection, (3) use gaze as an index of subject s attention to simplify signal analysis in natural environments, and (4) apply insights from two-person neuroscience into disorders of social interaction. Brain activity will be recorded with millisecond-accurate whole-scalp (306-channel) magnetoencepha-lography (MEG), associated with EEG, and with the millimeter-accurate 3-tesla functional magnetic reso-nance imaging (fMRI). Heart rate, respiration, galvanic skin response, and pupil diameter inform about body function. A new psychophysiological interaction setting will be built, comprising a two-person eye-tracking system. Novel analysis methods will be developed to follow the interaction and possible synchronization of the two persons signals. This uncoventional approach crosses borders of neuroscience, social psychology, psychophysiology, psychiatry, medical imaging, and signal analysis, with intriguing connections to old philosophical questions, such as intersubjectivity and emphatic attunement. The results could open an unprecedented window into human human, instead of just brain brain, interactions, helping to understand also social disorders, such as autism and schizophrenia. Further applications include master apprentice and patient therapist relationships. Advancing from studies of single persons towards two-person neuroscience shows promise of a break-through in understanding the dynamic social shaping of human brain and mind.

Summary "Economists' modern understanding of the functioning of markets is based on the behavioral assumption of individual rationality. Market agents are assumed to hold well-defined preferences and have perfect ability to draw Bayesian inferences in accordance with correct knowledge of the market model and market equilibrium. This research proposal is based on the premise that bounded rationality on the part of consumers is potentially a major source of market friction. My objective is to develop general theoretical tools to investigate this intuition, and to examine whether these tools can be insightfully applied to realistic market settings. So far, the literature on the subject has progressed as a sequence of specific models that capture one aspect of consumer psychology at a time. The challenge is to synthesize and generalize these models into flexible theoretical frameworks for modelling market interaction between profit-maximizing firms and boundedly rational consumers. Hopefully, various aspects of consumer psychology can be embedded into these frameworks, so that analytic results can be stated in terms of general, abstract properties of consumer behavior, rather than in terms of specific psychological effects. In turn, this general analysis is expected to lead to novel applications. Here are some of the general questions that I hope to address. Can we view certain aspects of firms' pricing and marketing strategies as responses to consumers' bounded rationality? To what extent are boundedly rational consumers vulnerable to exploitation by firms? Does competition protect them from exploitation? Does interaction between firms and boundedly rational consumers give rise to inefficiencies, and how are these affected by competition? What is the impact of various regulatory interventions in this context? Do market forces lead firms to ""educate"" or ""debias"" boundedly rational consumers? Does greater consumer rationality imply more competitive industry profits?"

Summary In the field of economics, individual decision making is the basic building block for studying complex environments such as markets, political systems, and social dynamics. Individual decision making is embodied in the neoclassical economically rational agent, whose only concern is the maximization of utility from his own material consumption. Two qualities of this agent are especially important for the research we will undertake: He has perfect understanding of the problems he faces - today and in the future - and unbounded computational ability to solve them. He also has no regard for the consumption of other members of the society or for their feelings about his actions. Huge empirical and experimental evidence shows that departure from these qualities is robust and significant. The failure of the existing models to incorporate bounded rationality and social concerns has proven critical in socially relevant and complex situations such as lifetime consumption and saving, taxation and expenditure policy, labour search and wage determination. The objective of this project is to bring these phenomena into the framework of neoclassical economics, to test their implications, and to tackle important applications. A novel and central feature of our approach is the attempt to retain the parsimonious methodological approach of economic modelling, which has scored groundbreaking successes in matters such as the design of auctions, markets, contracts, and voting mechanisms. Our project envisions the development of theory on individual decision making, the use of experiments to illuminate and test the theory, and the concrete application of theory - mainly to financial markets. The project will push the frontiers of the understanding of the above mentioned socially relevant situations. The explanatory power of our approach will be guaranteed by the continuous feed-back between theory and evidence- experimental and neuroexperimental, and by a departure from ad hoc modelling.

Summary Elementary particle physics is entering a spectacular new era in which experiments at the Large Hadron Collider (LHC) at CERN will soon start probing some of the deepest questions in physics, such as: Why is gravity so weak? Do elementary particles have substructure? What is the origin of mass? Are there new dimensions? Can we produce black holes in the lab? Could there be other universes with different physical laws? While the LHC pushes the energy frontier, the unprecedented precision of Atom Interferometry, has pointed me to a new tool for fundamental physics. These experiments based on the quantum interference of atoms can test General Relativity on the surface of the Earth, detect gravity waves, and test short-distance gravity, charge quantization, and quantum mechanics with unprecedented precision in the next decade. This ERC Advanced grant proposal is aimed at setting up a world-leading European center for development of a deeper theory of fundamental physics. The next 10 years is the optimal time for such studies to benefit from the wealth of new data that will emerge from the LHC, astrophysical observations and atom interferometry. This is a once-in-a-generation opportunity for making ground-breaking progress, and will open up many new research horizons.

Project Consistent computation of the chemistry-cloud continuum and climate change in Cyprus
Researcher (PI) Johannes Lelieveld
Host Institution (HI) THE CYPRUS RESEARCH AND EDUCATIONAL FOUNDATION
Call Details Advanced Grant (AdG), PE10, ERC-2008-AdG
Summary We have developed a new numerical method to consistently compute atmospheric trace gas and aerosol chemistry and cloud processes. The method is computationally efficient so that it can be used in climate models. For the first time cloud droplet formation on multi-component particles can be represented based on first principles rather than parameterisations. This allows for a direct coupling in models between aerosol chemical composition and the continuum between hazes and clouds as a function of ambient relative humidity. We will apply the method in a new nested global-limited area model system to study atmospheric chemistry climate interactions and anthropogenic influences. We will focus on the Mediterranean region because it is a hot spot in climate change exposed to drying and air pollution. The limited area model will also be applied as cloud-resolving model to study aerosol influences on precipitation and storm development. By simulating realistic meteorological conditions at high spatial resolution our method can be straightforwardly tested against observations. Central questions are: - How does the simulated haze-cloud continuum compare with remote sensing measurements and what is the consequence of abandoning the traditional and artificial distinction between aerosols and clouds? - How are cloud and precipitation formation influenced by atmospheric chemical composition changes? - To what extent do haze and cloud formation in polluted air exert forcings of synoptic meteorological conditions and climate? - Can aerosol pollution in the Mediterranean region exacerbate the predicted and observed drying in a changing climate? The model system is user-friendly and will facilitate air quality and climate studies by regional scientists. The project will be part of the Energy, Environment and Water Centre of the newly founded Cyprus Institute, provide input to climate impact assessments and contribute to a regional outreach programme.

Call Details Advanced Grant (AdG), LS4, ERC-2008-AdG
Summary Cardiac muscle death, unmatched by muscle cell creation, is the hallmark of acute myocardial infarction and chronic cardiomyopathies. The notion of heart failure as a muscle-cell deficiency disease has driven interest worldwide in ways to increase heart muscle cell number, by over-riding cell cycle constraints, suppressing cell death, or, most directly, cell grafting. Using stem cell antigen-1, we previously identified telomerase-expressing cells in adult mouse myocardium, which have salutary properties for bona fide cardiac regeneration. Here, we seek to address systematically the mechanisms for long-term self-renewal in Sca-1+ adult cardiac progenitor cells and in the smaller side population fraction, which is clonogenic and expresses telomerase at even higher levels. Specifically, we propose to study the roles of telomerase and of the telomere-capping protein, TRF2. Aim 1, Determine the properties of adult cardiac progenitor cells in mice that lack the RNA component of telomerase (TERC). Aim 2, Determine the properties of adult cardiac progenitor cells in mice that lack the catalytic component (TERT). To distinguish between effects of these two gene products themselves versus those that depend on cumulative telomere dysfunction, G2- and G5-null mice will be compared. Aim 3, Determine the properties of adult cardiac muscle and adult cardiac progenitor cells that lack the telomere-capping protein TRF2. Aim 4, Test the prediction that forced expression of TERT and TRF2 can augment cardiac muscle engraftment in vivo and enhance the clonal derivation of adult cardiac progenitor cells in vitro, without adversely affecting the cells differentiation potential. Work proposed in Aims 1-3 would provide indispensable fundamental information about the function of endogenous telomerase in adult cardiac progenitor cells. Conversely, work in Aim 4 would test potential therapeutic implications of telomerase and a telomere-capping protein with this auspicious population.

Summary "In recent years, we have made significant contributions to the understanding of the tumour suppressors p53, p16INK4a, and ARF, particularly in relation with cellular senescence and aging. The current project is motivated by two hypothesis: 1) that the INK4/ARF locus is a sensor of epigenetic damage and this is at the basis of its activation by oncogenes and aging; and, 2) that the accumulation of cellular damage and stress is at the basis of both cancer and aging, and consequently ""anti-damage genes"", such as tumour suppressors, simultaneously counteract both cancer and aging. With regard to the INK4/ARF locus, the project includes: 1.1) the generation of null mice for the Regulatory Domain (RD) thought to be essential for the proper regulation of the locus; 1.2) the study of the INK4/ARF anti-sense transcription and its importance for the assembly of Polycomb repressive complexes; 1.3) the generation of mice carrying the human INK4/ARF locus to analyze, among other aspects, whether the known differences between the human and murine loci are ""locus autonomous""; and, 1.4) to analyze the INK4/ARF locus in the process of epigenetic reprogramming both from ES cells to differentiated cells and, conversely, from differentiated cells to induced-pluripotent stem (iPS) cells. With regard to the impact of ""anti-damage genes"" on cancer and aging, the project includes: 2.1) the analysis of the aging of super-INK4/ARF mice and super-p53 mice; 2.2) we have generated super-PTEN mice and we will examine whether PTEN not only confers cancer resistance but also anti-aging activity; and, finally, 2.3) we have generated super-SIRT1 mice, which is among the best-characterized anti-aging genes in non-mammalian model systems (where it is named Sir2) involved in protection from metabolic damage, and we will study the cancer and aging of these mice. Together, this project will significantly advance our understanding of the molecular mechanisms underlying cancer and aging."

Summary Breast cancer is a major cause of death in the United States and the Western World. Advanced medical technologies and therapeutic strategies are necessary for the successful detection, diagnosis, and treatment of breast cancer. Here, we propose to use novel technologies (tissue microarrays (TMA) and automated quantivative bioimaging (AQUA)) to identify new therapeutic and prognostic markers for human breast cancer. More specifically, we will study the activation status of a new signaling pathway which we have implicated in breast cancer pathogenesis, using both mouse animal models and cells in culture. For this purpose, we will study the association of CAPER expression with pre-malignant lesions and progression from pre-malignancy to full-blown breast cancer. We expect that this new molecular marker will allow us to improve diagnostic accuracy for individual patients, enhancing both the prognostic predictions as well as the prediction of drug responsiveness for a given patient.

Summary We propose the development of novel nanodevices, such as nanoscale bridges and nanovectors, based on functionalized carbon nanotubes (CNT) for manipulating neurons and neuronal network activity in vitro. The main aim is to put forward innovative solutions that have the potential to circumvent the problems currently faced by spinal cord lesions or by neurodegenerative diseases. The unifying theme is to use recent advances in chemistry and nanotechnology to gain insight into the functioning of hybrid neuronal/CNT networks, relevant for the development of novel implantable devices to control neuronal signaling and improve synapse formation in a controlled fashion. The proposal s core strategy is to exploit the expertise of the PI in the chemical control of CNT properties to develop devices reaching various degrees of functional integration with the physiological electrical activity of cells and their networks, and to understand how such global dynamics are orchestrated when integrated by different substrates. An unconventional strategy will be represented by the electrical characterization of micro and nano patterned substrates by AFM and conductive tip AFM, both before and after neurons have grown on the substrates. We will also use the capability of AFM to identify critical positions in the neuronal network, while delivering time-dependent chemical stimulations. We will apply nanotechnology to contemporary neuroscience in the perspective of novel neuro-implantable devices and drug nanovectors, engineered to treat neurological and neurodegenerative lesions. The scientific strategy at the core of the proposal is the convergence between nanotechnology, chemistry and neurobiology. Such convergence, beyond helping understand the functioning and malfunctioning of the brain, can stimulate further research in this area and may ultimately lead to a new generation of nanomedicine applications in neurology and to new opportunities for the health care industry.

Project Context, Content, and Compositionality
Researcher (PI) François Recanati
Host Institution (HI) CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE CNRS
Call Details Advanced Grant (AdG), SH4, ERC-2008-AdG
Summary Over the past fifteen years, I have argued that the effects of context on content go well beyond what is standardly acknowledged in semantics. This view is sometimes referred to as Contextualism or (more technically) Truth-Conditional Pragmatics (TCP). The key idea is that the effects of context on content need not be traceable to the linguistic material in the uttered sentence. Some effects are due to the linguistic material (e.g. to context-sensitive words or morphemes which trigger the search for contextual values), but others result from top-down or free pragmatic processes that take place not because the linguistic material demands it, but because the literal meaning of the sentence requires adjustment or elaboration ( modulation ) in order to determine a contextually admissible content for the speaker s utterance. In the literature, one often finds arguments to the effect that, if Contextualism is right, then systematic semantics becomes impossible. More precisely, the claim that is often made is that TCP is incompatible with the Principle of Compositionality, upon which any systematic semantics must be based. The aim of this project is to defend Contextualism/TCP by demonstrating that it is not incompatible with the project of constructing a systematic, compositional semantics for natural language. This demonstration is of importance given the current predicament in the philosophy of language. We are, as it were, caught in a dilemma : formal semanticists provide compelling arguments that natural language must be compositional, but contextualists offer no less compelling arguments to the effect that « sense modulation is essential to speech, because we use a (mor or less) fixed stock of lexemes to talk about an indefinite variety of things, situations, and experiences » (Recanati 2004 : 131). What are we to do, if modulation is incompatible with compositionality? Our aim is to show that it is not, and thereby to dissolve the alleged dilemma.

Project Development and differentiation of CD8 T lymphocytes
Researcher (PI) Benedita Rocha
Host Institution (HI) INSTITUT NATIONAL DE LA SANTE ET DE LA RECHERCHE MEDICALE
Call Details Advanced Grant (AdG), LS6, ERC-2008-AdG
Summary CD8 T lymphocytes have a fundamental role in ensuring the control of different types of intracellular pathogens including bacteria, parasites and most viruses. This control may fail due to several reasons. The current aggressive anti-cancer therapies (or rarely certain congenital immune deficiencies) induce CD8 depletion. After bone-marrow transplantation, long time periods are required to ensure T cell reconstitution particularly in the adult. This long lag-time is due to the long-time periods required for hematopoietic precursors to generate T lymphocytes and to a thymus insufficiency in the adult. However, even when CD8 T cells are present CD8 immune responses are not always adequate. Certain chronic infections, as HIV, induce CD8 dysfunction and it is yet unclear how to generate efficient CD8 memory responses conferring adequate protection. To address these questions this project aims 1) To find strategies ensuring the rapid reconstitution of the peripheral and the gut CD8 T cell compartments a) by studying the mechanisms involved HSC division and T cell commitment; b) by isolating and characterizing progenitors we previously described that are T cell committed and able of an accelerated CD8 reconstitution c) by developing new strategies that may allow stable thymus transplantation and continuous thymus T cell generation. 2) To determine the mechanics associated to efficient CD8 memory generation a) by evaluating cellular modifications that ensure the efficient division and the remarkable accumulation and survival of CD8 T cells during the adequate immune responses as compared to inefficient responses b) by studying CD8 differentiation into effector and memory cells in both conditions. These studies will use original experiment mouse models we develop in the laboratory, that allow to address each of these aims. Besides state of the art methods, they will also apply unique very advanced approaches we introduced and are the sole laboratory to perform.

Call Details Advanced Grant (AdG), LS2, ERC-2008-AdG
Summary The idea of harnessing living organisms for treating human diseases is not new but, so far, the majority of the living vectors used in human therapy are viruses which have the disadvantage of the limited number of genes and networks that can contain. Bacteria allow the cloning of complex networks and the possibility of making a large plethora of compounds, naturally or through careful redesign. One of the main limitations for the use of bacteria to treat human diseases is their complexity, the existence of a cell wall that difficult the communication with the target cells, the lack of control over its growth and the immune response that will elicit on its target. Ideally one would like to have a very small bacterium (of a mitochondria size), with no cell wall, which could be grown in Vitro, be genetically manipulated, for which we will have enough data to allow a complete understanding of its behaviour and which could live as a human cell parasite. Such a microorganism could in principle be used as a living vector in which genes of interests, or networks producing organic molecules of medical relevance, could be introduced under in Vitro conditions and then inoculated on extracted human cells or in the organism, and then become a new organelle in the host. Then, it could produce and secrete into the host proteins which will be needed to correct a genetic disease, or drugs needed by the patient. To do that, we need to understand in excruciating detail the Biology of the target bacterium and how to interface with the host cell cycle (Systems biology aspect). Then we need to have engineering tools (network design, protein design, simulations) to modify the target bacterium to behave like an organelle once inside the cell (Synthetic biology aspect). M.pneumoniae could be such a bacterium. It is one of the smallest free-living bacterium known (680 genes), has no cell wall, can be cultivated in Vitro, can be genetically manipulated and can enter inside human cells.

Summary One of the major outcomes of recent studies on the formation of the Solar System is the reconnaissance of the fundamental importance of processes which took place during the first 10 thousands to 2 or 3 millions years of the lifetime of the Sun and its accretion disk. Astrophysical observations in the optical to infrared wavelengths of circumstellar disks around young stars have shown the existence in the inner disk of high-temperature processing of the dust. X-ray observations of T-Tauri stars revealed that they exhibit X-ray flare enhancements by several orders of magnitude. The work we have performed over the last years on the isotopic analysis of either solar wind trapped in lunar soils or of Ca-, Al-rich inclusions and chondrules from primitive chondrites, has allowed us to link some of these astrophysical observations around young stars with processes, such as irradiation by energetic particles and UV light, which took place around the T-Tauri Sun. The aim of this project is to make decisive progress in our understanding of the early solar system though the development of in situ high-precision isotopic measurements by ion microprobe in extra-terrestrial matter. The project will be focused on the exploration of the variations in the isotopic composition of O and Mg and in the concentration of short-lived radioactive nuclides, such as 26Al and 10Be, with half-lives shorter than 1.5 millions years. A special emphasis will be put on the search for nuclides with very short half-lives such as 32Si (650 years) and 14C (5730 years), nuclides which have never been discovered yet in meteorites. These new data will bring critical information on, for instance, the astrophysical context for the formation of the Sun and the first solids in the accretion disk, or the timing and the processes by which protoplanets were formed and destroyed close to the Sun during the first 2 million years of the lifetime of the Solar System.

Call Details Advanced Grant (AdG), LS3, ERC-2008-AdG
Summary Centrosome duplication entails the formation of a single procentriole next to each centriole once per cell cycle. The mechanisms governing procentriole formation are poorly understood and constitute a fundamental open question in cell biology. We will launch an innovative multidisciplinary research program to gain significant insight into these mechanisms using C. elegans and human cells. This research program is also expected to have a significant impact by contributing important novel assays to the field. Six specific aims will be pursued: 1) SAS-6 as a ZYG-1 substrate: mechanisms of procentriole formation in C. elegans. We will test in vivo the consequence of SAS-6 phosphorylation by ZYG-1. 2) Biochemical and structural analysis of SAS-6-containing macromolecular complexes (SAMACs). We will isolate and characterize SAMACs from C. elegans embryos and human cells, and analyze their structure using single-particle electron microscopy. 3) Novel cell-free assay for procentriole formation in human cells. We will develop such an assay and use it to test whether SAMACs can direct procentriole formation and whether candidate proteins are needed at centrioles or in the cytoplasm. 4) Mapping interactions between centriolar proteins in live human cells. We will use chemical methods developed by our collaborators to probe interactions between HsSAS-6 and centriolar proteins in a time- and space-resolved manner. 5) Functional genomic and chemical genetic screens in human cells. We will conduct high-throughput fluorescence-based screens in human cells to identify novel genes required for procentriole formation and small molecule inhibitors of this process. 6) Mechanisms underlying differential centriolar maintenance in the germline. In C. elegans, we will characterize how the sas-1 locus is required for centriole maintenance during spermatogenesis, as well as analyze centriole elimination during oogenesis and identify components needed for this process

Call Details Advanced Grant (AdG), LS5, ERC-2008-AdG
Summary Neuroscience is one of the fastest-developing areas of science, but it is fair to say that we are still far from understanding how the brain produces subjective experience. For example, simple questions about the origin of thought, imagination, social interaction, or feelings lack even rudimentary answers. We have learnt much about the workings of individual cells and synapses, but psychological phenomena cannot be understood only at this level. These phenomena all emerge from interactions between large numbers of diverse cells in intermingled neural circuits. A major obstacle has been the absence of concepts and tools for investigating neural computation at the circuit level. The aim of this proposal is to combine new transgenic methods for cell type-specific intervention with large-scale multisite single-cell recording to determine how a basic cognitive function self-localization is generated in a functionally well-described mammalian neural circuit. We shall use our recent discovery of entorhinal grid cells as an access ramp. Grid cells fire only when the animal moves through certain locations. For each cell, these locations define a periodic triangular array spanning the whole environment. Grid cells co-exist with other entorhinal cell types encoding head direction, geometric borders, or conjunctions of features. This network is thought to form an essential part of the brain s coordinate system for metric navigation but the detailed wiring, the mechanism of grid formation, and the function of each morphological and functional cell type all remain to be determined. We shall address these open questions by measuring how dynamic spatial representation is affected by transgene-induced activation or inactivation of the individual components of the circuit. The endeavour will pioneer the functional analysis of neural circuits and may, perhaps for the first time, provide us with mechanistic insight into a non-sensory cognitive function in the mammalian cortex.

Project The Europeanisation of Citizenship in the Successor States of the Former Yugoslavia

Host Institution (HI) THE UNIVERSITY OF EDINBURGH
Call Details Advanced Grant (AdG), SH2, ERC-2008-AdG
Summary CITSEE is a comparative and contextualised study of the citizenship regimes of the seven successor states of the former Yugoslavia (SFRY) in their broader European context. It focuses on the relationship between how these regimes have developed after the disintegration of SFRY and the processes of re-integration occurring in the context of the enlargement of the European Union applied in the region. It makes use of the varied statuses under EU law of the SFRY successor states, of which only Slovenia is so far a Member State. The processes at the heart of the study include the effects of previous and prospective enlargements of the EU and the broader stabilisation and association processes. CITSEE uses methods which look at legal and institutional change in its broader political context and applies the broad approach of constitutional ethnography. It has national case studies and thematic case studies of key issues which have a transnational dimension, including the status of residents of the former SFRY Republics resident in other Republics at the moment of independence, dual and multiple nationality, the granting or denial of political rights for resident non-nationals and non-resident nationals, the status of minorities such as the Roma, gender issues arising in a citizenship context, and the impact of citizenship concepts on free movement and travel across borders. While CITSEE s objectives are not normative in nature, and are not intended to supply answers as to best or worst practices in relation to citizenship regimes, or to evaluate the impact of Europeanisation as negative or positive, none the less such an evaluative study is likely to be of interest not only to researchers, but also to NGOs and to policy-makers in the region and in the EU and other international institutions because it fills in many gaps in our current knowledge and provides improved evidence on the basis of which policies may be developed in the future.

Call Details Advanced Grant (AdG), PE8, ERC-2008-AdG
Summary The key objective of this project is to promote cleaner and more efficient combustion technologies through the development of theoretically grounded and more accurate chemical models. This is motivated by the fact that the current models which have been developed for the combustion of constituents of gasoline, kerosene, and diesel fuels do a reasonable job in predicting auto-ignition and flame propagation parameters, and the formation of the main regulated pollutants. However their success rate deteriorates sharply in the prediction of the formation of minor products (alkenes, dienes, aromatics, aldehydes) and soot nano-particles, which have a deleterious impact on both the environment and on human health. At the same time, despite an increasing emphasis in shifting from hydrocarbon fossil fuels to bio-fuels (particularly bioethanol and biodiesel), there is a great lack of chemical models for the combustion of oxygenated reactants. The main scientific focus will then be to enlarge and deepen the understanding of the reaction mechanisms and pathways associated with the combustion of an increased range of fuels (hydrocarbons and oxygenated compounds) and to elucidate the formation of a large number of hazardous minor pollutants. The core of the project is to describe at a fundamental level more accurately the reactive chemistry of minor pollutants within extensively validated detailed mechanisms for not only traditional fuels, but also innovative surrogates, describing the complex chemistry of new environmentally important bio-fuels. At the level of individual reactions rate constants, generalized rate constant classes and molecular data will be enhanced by using techniques based on quantum mechanics and on statistical mechanics. Experimental data for validation will be obtained in well defined laboratory reactors by using analytical methods of increased accuracy.

Call Details Advanced Grant (AdG), LS1, ERC-2008-AdG
Summary The complement system is a regulatory pathway in mammalian plasma that enables the host to recognize and clear invading pathogens and altered host cells, while protecting healthy host tissue. This regulatory system consists of ~30 large multi-domain plasma and cell-surface proteins, that act in concert through an interplay of proteolysis and complex formations on target membranes. We study the molecular events on membranes that ensure initiation and amplification of the response, protection of host cells and activation of immune responses leading to cell lysis, phagocytosis and B-cell stimulation.
In the past few years, we have resolved the structural details of the large complement proteins involved in the central, aspecific labelling and amplification step; with recent data we revealed the structural basis of the assembly and activity of the protease complex associated with this step. These insights into the central aspecific reaction, and the experiences gained on working with these large multi-domain proteins and complexes, give us an excellent starting point to addres the questions of specificity, protection and activation of immune cells.
The goal of the proposal is to elucidate the multivalent molecular mechanisms of recognition, regulation and immune cell activation of the complement system on target membranes. We will use protein crystallography and electron microscopy to study the interactions and conformational changes involved in protein complex formation, and (single-molecule) fluorescence to resolve the multivalent molecular events, the conformational states and transitions that occur on the membrane. The combined data will provide mechanistic insights into the specifity of immune clearance by the complement system.
Understanding the molecular mechanisms of complement activation and regulation will be instrumental in developing more potent therapeutics to control infections, prevent tissue damage and fight tumours by immunotherapies.
Summary
The complement system is a regulatory pathway in mammalian plasma that enables the host to recognize and clear invading pathogens and altered host cells, while protecting healthy host tissue. This regulatory system consists of ~30 large multi-domain plasma and cell-surface proteins, that act in concert through an interplay of proteolysis and complex formations on target membranes. We study the molecular events on membranes that ensure initiation and amplification of the response, protection of host cells and activation of immune responses leading to cell lysis, phagocytosis and B-cell stimulation.

Call Details Advanced Grant (AdG), PE3, ERC-2008-AdG
Summary Collective behaviour is a widespread phenomenon in nature and technology making it a very important subject to study in various contexts. The main goal we intend to achieve in our multidisciplinary research is the identification and documentation of new unifying principles describing the essential aspects of collective motion, being one of the most relevant and spectacular manifestations of collective behaviour. We shall carry out novel type of experiments, design models that are both simple and realistic enough to reproduce the observations and develop concepts for a better interpretation of the complexity of systems consisting of many organisms and such non-living objects as interacting robots. We plan to study systems ranging from cultures of migrating tissue cells through flocks of birds to collectively moving devices. The interrelation of these systems will be considered in order to deepen the understanding of the main patterns of group motion in both living and non-living systems by learning about the similar phenomena in the two domains of nature. Thus, we plan to understand the essential ingredients of flocking of birds by building collectively moving unmanned aerial vehicles while, in turn, high resolution spatiotemporal GPS data of pigeon flocks will be used to make helpful conclusions for the best designs for swarms of robots. In particular, we shall construct and build a set of vehicles that will be capable, for the first time, to exhibit flocking behaviour in the three-dimensional space. The methods we shall adopt will range from approaches used in statistical physics and network theory to various new techniques in cell biology and collective robotics. All this will be based on numerous prior results (both ours and others) published in leading interdisciplinary journals. The planned research will have the potential of leading to ground breaking results with significant implications in various fields of science and technology.

Summary I propose to use computer simulations to predict the thermodynamic stability and kinetics of formation of three-dimensional structures of DNA-linked colloids. I then aim to go beyond simple binary structures and use simulation to explore novel strategies to build multi-component three-dimensional colloidal structures. At present, the complexity of self-assembled colloidal crystals is limited: ordered structures with more than two distinct components are rare. To make more complex structures, particles should bind selectively to their designated neighbours. This may be achieved by coating colloids with single-stranded DNA that hybridises selectively with the complementary sequence on another colloid. However, there are many practical obstacles to go from there to the self assembly of multi-component structures. In order to make progress, we need to understand the factors that determine the thermodynamic stability and, even more importantly, the kinetics of formation of complex structures. Such a numerical study will require a wide range of numerical techniques, many of which do not yet exist. As I have played a key role in the development of the numerical methods to study both the stability and the kinetics of formation of simple colloidal crystals, I am well positioned to make a breakthrough that should have important implications for experimental work in this field. My research will focus on DNA-linked colloidal systems, as this is an active area of experimental research. However, I stress that many of the techniques that I aim to develop are general. During the project, I aim to study the factors that influence the equilibrium phase diagram and the kinetics of passive and active self-assembly of (multi-component) DNA-colloid systems During the project, I aim to study the factors that influence the equilibrium phase diagram and the kinetics of passive and active self-assembly of (multi-component) DNA-colloid systems

Summary Cancer care will be revolutionized over the next decade by the introduction of novel therapeutics that target the underlying molecular mechanisms of the disease. With the advent of human genetics, a plethora of genes have been correlated with human diseases such as cancer the SNP maps. Since the sequences are now available, the next big challenge is to determine the function of these genes in the context of the entire organism. Genetic animal models have proven to be extremely valuable to elucidate the essential functions of genes in normal physiology and the pathogenesis of disease. Using gene-targeted mice we have previously identified RANKL as a master gene of bone loss in arthritis, osteoporosis, and cancer cell migration and metastases and genes that control heart and kidney function; wound healing; diabetes; or lung injury Our primary goal is to use functional genomics in Drosophila and mice to understand cell transformation, invasion, and cancer metastases of epithelial tumors. The following projects are proposed: 1. Role of the key osteoclast differentiation factors RANKL-RANK and its downstream signalling cascade in the development of breast and prostate cancer. 2. Requirement of osteoclasts for bone metastases and stem cell niches using a new RANKfloxed allele; function of RANKL-RANK in local tumor cell invasion. 3. Role of RANKL-RANK in the central fever response to understand potential implications of future RANKL-RANK directed therapies. 4. Integration of gene targeting in mice with state-of-the art technologies in fly genetics; use of whole genome tissue-specific in vivo RNAi Drosophila libraries to identify essential and novel pathways for cancer pathogenesis using whole genome screens. 5. Role of TSPAN6, as a candidate lung metastasis gene. Identification of new cancer disease genes will allow us to design novel strategies for cancer treatment and will have ultimately impact on the basic understanding of cancer, metastases, and human health.

Project Consumer culture in an age of anxiety: political and moral economies of food

Host Institution (HI) THE UNIVERSITY OF SHEFFIELD
Call Details Advanced Grant (AdG), SH3, ERC-2008-AdG
Summary Food safety and security are high priority issues throughout Europe at present, the subject of intense government concern, public interest, media speculation and academic scrutiny. With few exceptions, academic research on food has been fragmented with too little interaction between food scientists, health researchers and social scientists. This application builds on the success of a recently completed research programme (Changing Families, Changing Food, 2005-8) which brought together an inter-disciplinary team of over 40 researchers from the food, health and social sciences to address the complex relationships between families and food which lie at the heart of current concerns about food safety and public health. The current proposal aims to take forward the findings of that programme regarding the socially embedded nature of contemporary food choice and to make a step change in our understanding of contemporary consumer anxiety through a focused and concerted programme of research on the political and moral economies of food. The project focuses on consumer anxieties about food at a range of geographic scales, from the global scale of international food markets to the domestic scale of individual households. By taking a whole chain approach -- examining food production and consumption at all points along the chain from farm to fork -- the findings of our research will enable a major advance in our understanding of contemporary anxieties around food, with tangible effects on public health (including the reduction of obesity, diabetes and coronary heart disease).

Summary The goal of this project is to study conformally invariant fractal structures from the perspectives of analysis, dynamics, probability, geometry and physics, emphasizing interrelations of these fields. In the last two decades such structures emerged in several areas: continuum scaling limits of 2D critical models in statistical physics (percolation, Ising model); extremal configurations for various problems in complex analysis (multifractal harmonic measures, coefficient growth of univalent maps, Brennan's conjecture); chaotic sets for complex dynamical systems (Julia sets, Kleinian groups). Capitalizing on recent successes, I plan to continue my work in these areas, exploiting their interactions and connections to physics. I intend to achieve at least some of the following goals: * To establish that several critical lattice models have conformally invariant scaling limits, by building upon results on percolation and Ising models and finding discrete holomorphic observables. * To study geometric properties of arising fractal curves and random fields by connecting them to Schramm's SLE curves and Gaussian Free Fields. * To investigate massive scaling limits by describing them geometrically with generalizations of SLEs. * To lay mathematical framework behind relevant physical notions, such as Coulomb Gas (by relating height functions to GFFs) and Quantum Gravity (by identifying limits of random planar graphs with Liouville QGs). * To improve known bounds in several old questions in complex analysis by studying multifractal spectra of harmonic measures. * To estimate extremal behavior of such spectra by using holomorphic motions of (quasi) conformal maps and thermodynamic formalism. * To understand nature of extremal multifractals for harmonic measure by studying random and dynamical fractals. The topics involved range from century old to very young ones. Recently connections between them started to emerge, opening exciting possibilities for new developments in some long standing open problems.

Summary This project aims to establish criteria by which results from language contact studies can be used to strengthen the field of historical linguistics. It does so by applying the scenario model for language contact studies to a number of concrete settings, which differ widely in their level of aggregation and dime depth: the languages of the Amazonian fringe in South America, the complex multilingual setting of the Republic of Suriname, the multilingual interaction of immigrant groups in the Netherlands, and two groups of multilingual individuals. New methods from structural phylogenetics are employed, and the same linguistic variables (TMA and evidentiality marking, argument realization) will be studied in the various projects. In the various projects, use will be made from a shared questionnaire, so that comparable data can be gathered. By applying the scenaio model at various levels of aggregation, a more principled link between language contact studies and historical linguistics can be established.

Summary Cooperation poses a problem to evolutionary theory because it can be exploited by selfish individuals. Evolutionary biologists have developed a detailed theoretical overview of possible solutions to the problem of cooperation. In contrast to our theoretical understanding of potential solutions, however,, we have been relatively unsuccessful at applying theory to understand observations of cooperative behaviour nature. We present a novel and interdisciplinary programme of research to address this problem by empirically testing assumptions and predictions of several leading explanations for cooperation. We will develop theory to make explicit testable predictions for specific systems. We will exploit the advantage offered by different study systems: experiments with bacteria, comparative studies on cooperative breeding vertebrates, and experiments on humans. In addition to addressing specific hypotheses, we will show how evolutionary theory links and differentiates explanations for cooperation across various taxa and levels of biological organization.

Summary The Applicant has an outstanding record of achievement and an international reputation for independent research across many areas of metal coordination chemistry. This high-impact and challenging Proposal brings together innovative ideas in coordination chemistry within a single inter- and multi-disciplinary project to open up new horizons across molecular and biological sciences, materials science and energy research. The Proposal applies coordination chemistry to the key issues of climate change, environmental and chemical sustainability, the Hydrogen Economy, carbon capture and fuel cell technologies, and atom-efficient metal extraction and clean-up. The vision is to bring together complementary areas and new applications of metal coordination chemistry and ligand design within an overarching and fundamental research program addressing: i. nanoscale functionalized framework polymers for the storage and activation of H2, CO2, CO, O2, N2, methane and volatile organic compounds; ii. new catalysts for the reversible oxidation and photochemical production of H2; iii) clean and selective recovery of precious metals (Pt, Pd, Rh, Ir, Hf, Zr) from process streams and ores. These research themes will be consolidated within a single cross-disciplinary and ambitious program focusing on the control of chemistry, reactivity and interactions within self-assembled confined and multi-functionalized space generated by designer porous framework materials. An AdG will afford the impetus and freedom via consolidated funding to undertake fundamental, speculative research with multiple potential big-hits across a wide range of disciplines. Via an extensive network of international academic and industrial collaborations, the Applicant will deliver major research breakthroughs in these vital areas, and train scientists for the future of Europe in an exciting, stimulating and curiosity-driven environment.

Summary Neurons in primary visual cortex (area V1) receive feedforward inputs from thalamic afferents and lateral inputs from other cortical neurons. Little is known about how these components interact to determine the responses of a V1 neuron. One camp ascribes most responses to feedforward mechanisms. The other camp ascribes them mostly to lateral interactions. We propose that these two apparently opposed views can be simply reconciled in a single framework. We hypothesize that area V1 can operate both in a feedforward regime and in a lateral interaction regime, depending on the nature of the stimulus and on the cognitive task at hand, and that the transition from one regime to the other is governed by synaptic inhibition. We will test these hypotheses by recording from individual V1 neurons while monitoring the activity of nearby populations of cortical neurons via multiprobe electrodes. In Aim 1 we will relate the activity of V1 neurons to that of nearby populations. We will use simple measures of correlation and nonlinear models that predict individual spikes to measure how responses depend on a feedforward contribution (the receptive field ) and on a lateral contribution (the connection field ). We will test our first hypothesis, concerning the role of the stimulus in changing this dependence. In Aim 2 we will extend these results to a behaving animal. We will record from V1 of mice performing a 2-alternative forced-choice psychophysical task, and we will test our second hypothesis, concerning the role of the cognitive task in determining the operating regime of the cortex. In Aim 3 we will seek a biophysical interpretation of the functional mechanisms and effective connectivity revealed by the previous Aims. We will test our third hypothesis, concerning the role of synaptic inhibition. The tools involved will include intracellular recordings and optical stimulation in transgenic mice whose cortical neurons are sensitive to light.

The spectroscopic measurements using tunable narrow-band vacuum-ultraviolet and millimeter wave radiation sources will be performed on cold samples in supersonic beams as well as on trapped samples of translationally cold Rydberg atoms and molecules. To this end, our recent approach to trap H atoms in Rydberg states electrostatically (Hogan and Merkt, Phys. Rev. Lett. 100, 043001 (2008)) will be extended to molecules, and the possibility of transfering the trapped species from electrostatic traps to magnetic and optical traps will be explored.

The spectroscopic measurements using tunable narrow-band vacuum-ultraviolet and millimeter wave radiation sources will be performed on cold samples in supersonic beams as well as on trapped samples of translationally cold Rydberg atoms and molecules. To this end, our recent approach to trap H atoms in Rydberg states electrostatically (Hogan and Merkt, Phys. Rev. Lett. 100, 043001 (2008)) will be extended to molecules, and the possibility of transfering the trapped species from electrostatic traps to magnetic and optical traps will be explored.

Summary Quantum computers offer a fundamentally new way of information processing. Within the scope of this proposal, quantum information processing with an ion trap quantum computer will be investigated. With the new combination of cryogenic technology and ion traps for quantum computing we intend to build a quantum information processor with strings of up to 50 ions and with two-dimensional ion arrays for an investigation of deterministic many-particle entanglement. The cryogenic traps will be applied for quantum simulations, for fundamental investigations concerning large-scale entanglement and for precision measurements enhanced by quantum metrology techniques employing entangled particles.

Summary We study DNA damage and genome stability and its impact on human health using nucleotide excision repair (NER) as paradigm. Patients with NER defects present a perplexing clinical heterogeneity ranging from extreme cancer predisposition to dramatic neurodevelopmental deficits. To elucidate the underlying mechanism we adopted an integral strategy from gene to patient and contributed to resolving the NER reaction in vitro and its dynamic organization in vivo, using molecular genetics, advanced life cell imaging and photobleaching. Mouse NER mutants revealed an unexpected link between DNA damage and (premature) aging, as strong as the DNA damage-cancer connection. We found a striking correlation between type/severity of the repair defect and degree of premature aging, with some mutants dying of aging in 3 weeks! Pathological and functional analysis and expression profiling confirmed that this is bona fide aging. Conditional mutants allowed targeting accelerated aging to specific organs/stages of development e.g. dramatic aging only in brain. Expression profiling revealed that short-lived repair mutants mount a survival response that attempts to extend lifespan by investing in defenses at the expense of growth. The ambitious objective of this multi-disciplinary proposal is to obtain an integral understanding of the biological/medical impact of DNA damage and the important survival response, with emphasis on rational-based prevention and intervention strategies for cancer and other aging-related diseases using the rapidly aging mouse mutants as tools. Triggering the survival response at adulthood is expected to postpone many aging-related diseases including cancer and to strongly improve quality of life at later age. We already identified compounds that influence rapid aging in mice and demonstrated the potency of the survival response to withstand ischemia reperfusion damage. Thus, this proposal addresses the major medical challenges faced by our society.

Project Soil Foundation Structure Systems Beyond Conventional Seismic Failure Thresholds: Application to New or Existing Structures and Monuments
Researcher (PI) George Gazetas
Host Institution (HI) NATIONAL TECHNICAL UNIVERSITY OF ATHENS - NTUA
Call Details Advanced Grant (AdG), PE8, ERC-2008-AdG
Summary The main goal of the proposed research is to investigate the possibility of allowing below-ground support systems to respond to strong seismic shaking by going beyond a number of thresholds that would conventionally imply failure and are today forbidden by codes. Such thresholds include : (a) sliding at the soil-foundation interface ; (b) separation and uplifting of a shallow foundation from the soils ; (c) mobilization of bearing capacity failure mechanism for shallow foundations ; (d) structural yielding of pile foundations ; (e) combination of some of the above. Whereas under static loading conditions a slight exceedance of such thresholds leads to failure, the oscillatory nature of seismic shaking will allow such exceedances for a short period of time, with perhaps no detrimental or irreparable consequences. The latter take the form of permanent foundation displacements, rotations, or injuries , which the designer will aspire to confine within rational limits. The motivation and the need for this research has come from : (i) observations of actual behaviour in a variety of earthquakes ; conspicuous examples : the permanent tilting , overturning, and often survival of numerous buildings on extremely soft soil in Adapazari during the Kocaeli 1999 earthquake ; (ii) the foundation design of a number of critical structures (e.g., major bridge pier, air control tower, tall monuments, elevated water tanks,) against large seismic actions ; the disproportionately large overturning moment and/or base shear force of such slender structures can hardly be faced with today s conventional foundation methods, (iii) the need to seismically retrofit and rehabilitate older structures and historical monuments; (iv) structural yielding of pile foundations is now detectable (thanks to technological advances), thus eliminating one of the reasons for avoiding it.

Summary Wireless and mobile communication systems have become an important part of our daily environment. Since the introduction of the GSM-network in the early nineties, different wireless applications such as WiFi, Bluetooth, GPS, etc. have been brought into the market. This has become possible due to the high integration of integrated circuits in relatively cheap technologies. Besides the digital signal processing, those wireless applications require complex analog circuits operating at very high frequencies (RF circuits). In the early days these were implemented as discrete components or standalone ICs in expensive technologies such as GaAs, InP and SiGe. Due to the research towards nanometer CMOS technologies, and due to improved RF circuit techniques, RF-CMOS has been introduced since the mid nineties. The intention of this research project is to take the next big leap forward in wireless applications, i.e. the exploration and research, based on the vast RF-CMOS knowledge already existing, towards the Extremely High Frequencies which is above 70 GHz up to 300GHz, with wavelengths close to 1 mm. The research project is a logical evolution of the RF-CMOS research knowledges of the team. For that the "natural evolution" acronym DARWIN (Deep mm-Wave RF CMOS Integrated Circuits (with the M of CMOS inverted (W)) is choosen. Implementing circuit techniques in standard CMOS technologies at those frequencies is again an enormous challenge and will open a lot of new opportunities and applications towards the future due to possibilities in safety monitoring, e.g. collision radar detection for automobiles at 77 GHz, the need for high data-rate telecommunication systems, with capacity of 1-10 Gbps, and imaging for medical and security systems. The goal of the proposed project is to perform the necessary fundamental basic research to be able to implement these 70-300 GHz applications in CMOS technology (45 nm and below).

Call Details Advanced Grant (AdG), PE10, ERC-2008-AdG
Summary Knowledge of the physical and chemical state of the Earth s inner silicate mantle is central to our understanding of plate tectonics, mantle convection, magma generation and the composition of the Earth as a whole. The key to this knowledge is the ability to interpret studies of seismic wave velocities through the deep Earth using laboratory measurements of mineral sound velocities at high pressures and temperatures. Scientists have for many years measured these properties as a function of pressure but due to the experimental difficulties the majority of studies have been performed only at room temperature. Large extrapolations of these data to mantle temperatures are required to link seismic velocity observations with physical and chemical properties of mantle rocks, resulting in large uncertainties that obscure firm conclusions. An additional uncertainty arises because there is currently no primary scale for accurately measuring pressure at high temperatures. In this study mineral sound velocities and densities will be measured in the diamond anvil cell at simultaneous high pressures and high temperatures to at least 50 GPa and 1300K. This will be possible by a pioneering combination of Brillouin scattering spectroscopy, to measure sound velocities, and single crystal X-ray diffraction determinations of density. By making both types of measurements on the same sample while it is maintained at a constant pressure and temperature, the pressure can be independently measured. These absolute pressure determinations will be used to derive a new universal pressure scale for use at high temperatures. Sound velocities of the major mantle minerals will be determined at high temperatures and absolute pressures thereby drastically decreasing the uncertainties in velocity calculations for rock assemblages at deep mantle conditions. The resulting data will be employed to finally interpret a host of seismic observations made at both global and local scales.

Summary The study of consciousness is considered one of the final frontiers in science. After centuries of introspection, philosophy, and psychology it is thought that neuroscience will now answer the age-old questions like who is conscious, when, and what of. This will take more, however, than the current approach of finding the neural correlate of consciousness (NCC). We need a new science of consciousness. What is the problem? Behaviour is considered the gold standard of consciousness: when someone says he is conscious, he is, and when he says not, he isn t. But it is impossible to reliably gauge the presence or absence of conscious sensations from behaviour. We will always conflate consciousness with cognitive functions enabling the report, such as attention, working memory or language. Finding the NCC is doomed to fail. Instead, arguments from neuroscience should be allowed to reshape the definition of consciousness. Behavioural or introspective ideas may be a starting point, but ultimately, neural arguments should be allowed to overrule behavioural evidence. I will show how a new neuro-behavioural definition of consciousness can dissociate consciousness from cognition, explains key features of conscious experience, and allows us to understand consciousness at a much more fundamental level. Experiments in man and monkey will test essential predictions of the new definition of consciousness, using techniques such as intracortical recording, EEG, fMRI and pharmacological intervention, combined with psychophysics, learning paradigms or manipulations of consciousness. If these confirm the idea, the new definition of consciousness should be adopted. This means we are in for a change. The new definition of consciousness will move our notion of mind towards that of brain. The sacred first person perspective on consciousness has to be given up. What we may gain, however, is a much better science of consciousness.

Summary Important methods and results in discrete mathematics arise from the interaction between discrete mathematics and ``continuous'' areas like analysis or geometry. Classical examples of this include topological methods, linear and semidefinite optimization generating functions and more. More recent areas stressing this connection are the theory of limit objects of growing sequences of finite structures (graphs, hypergraphs, sequences), differential equations on networks, geometric representations of graphs. Perhaps most promising is the study of limits of growing graph and hypergraph sequences. In resent work by the Proposer and his collaborators, this area has found highly nontrivial connections with extremal graph theory, the theory of property testing in computer science, to additive number theory, the theory of random graphs, and measure theory as well as geometric representations of graphs. This proposal's goal is to explore these interactions, with the participation of a number of researchers from different areas of mathematics.

Summary Discrete Mathematics is a fundamental mathematical discipline as well as an essential component of many mathematical areas, and its study has experienced an impressive growth in recent years. Some of the main reasons for this growth are the broad applications of tools and techniques from extremal and probabilistic combinatorics in the rapid development of theoretical Computer Science, in the spectacular recent results in Additive Number Theory and in the study of basic questions in Information Theory. While in the past many of the basic combinatorial results were obtained mainly by ingenuity and detailed reasoning, the modern theory has grown out of this early stage, and often relies on deep, well developed tools, like the probabilistic method, algebraic, topological and geometric techniques. The work of the principal investigator, partly jointly with several collaborators and students, and partly in individual efforts, has played a significant role in the introduction of powerful algebraic, probabilistic, spectral and geometric techniques that influenced the development of modern combinatorics. In the present project he aims to try and further develop such tools, trying to tackle some basic open problems in Combinatorics, as well as significant questions in Additive Combinatorics, Information Theory, and theoretical Computer Science. Progress on the problems mentioned in this proposal, and the study of related ones, is expected to provide new insights on these problems and to lead to the development of novel fruitful techniques that are likely to be useful in Discrete Mathematics as well as in related areas.

Summary Developmental biology seeks not only to learn more about the fundamental processes of growth and pattern per se, but to understand how they synergize to enable the morphogenesis of multicellular organisms. Our goal is to perform real-time analyses of these developmental processes in an intact developing organ. By applying a vital imaging approach, we can circumvent the normal limitations of inferring cellular dynamics from static images or molecular data, and obtain the real dynamic view of growth and patterning. The wing imaginal disc of Drosophila, which starts out as a simple epithelial structure and gives rise to a precisely structured adult limb, will serve as an ideal model system. This system has the combined advantages of relative simplicity and genetic tractability. We will create several innovations that expand the current toolkit and thus facilitate the detailed dissection of growth and patterning. A key early step will be to develop novel reporters to dynamically and faithfully monitor signaling cascades involved in growth and patterning, such as the Dpp and Hippo pathways. We will also implement quantification techniques that are currently being set up in collaboration with an experimental physicist, to deduce, and alter, the mechanical forces that develop in the cells of a growing tissue. The large amount of quantitative data that will be generated allow us derive computational models of the individual pathways and their interaction. The focus of the study will be to answer the following questions: 1) Is the Hippo pathway regulated spatially and temporally, and by what signaling pathways? 2) Do mechanical forces play a pivotal controlling role in organ morphogenesis? 3) What are the global effects on growth, when pathways controlling patterning, cell competition or compensatory proliferation are perturbed? The proposed project will bring the approaches taken to define the mechanisms underlying and controlling growth and patterning to the next level.

Call Details Advanced Grant (AdG), LS9, ERC-2008-AdG
Summary Certain plants, animals and micro-organisms are able to dry out completely and yet remain viable, a phenomenon known as anhydrobiosis ( life without water ), or desiccation tolerance. This proposal addresses the molecular mechanisms responsible for desiccation tolerance and aims to confer these mechanisms on desiccation-sensitive mammalian cells, establishing a new field in biotechnology: a form of synthetic biology we have called anhydrobiotic engineering. One feature of anhydrobiotic organisms is the production of many examples of highly hydrophilic proteins (or hydrophilins ) in preparation for severe dehydration. Although data are limited, these hydrophilins are suggested to fulfil various roles in preserving homeostasis of the desiccating cell, including the maintenance of protein, nucleic acid and membrane structure. The proposed project will investigate the function of hydrophilins, engineer these and other elements as desiccation protection modules, and introduce modules into mammalian cell lines. By combining protection modules and using an iterative deployment strategy, we aim to achieve an engineered mammalian cell with high viability in the dried state. Anhydrobiotic engineering will find applications in cell banking, e.g. of hybridoma collections, and cell-based technologies including tissue engineering. Principles established should be applicable to agriculture, where drought-resistant crops, or desiccation-tolerant biopesticides are envisaged. The PI has a distinguished record of achievement in several disciplines in the life sciences and biotechnology, in both academia and industry. Publications in Nature, Science and other leading journals include contributions in human genomics, the molecular genetics of the immune system and inherited disease, the molecular cell biology and biochemistry of desiccation tolerance, and invertebrate genetics. The PI is also an inventor on licensed patents and patent applications in two different fields.

Principles established should be applicable to agriculture, where drought-resistant crops, or desiccation-tolerant biopesticides are envisaged. The PI has a distinguished record of achievement in several disciplines in the life sciences and biotechnology, in both academia and industry. Publications in Nature, Science and other leading journals include contributions in human genomics, the molecular genetics of the immune system and inherited disease, the molecular cell biology and biochemistry of desiccation tolerance, and invertebrate genetics. The PI is also an inventor on licensed patents and patent applications in two different fields.

Summary Error correcting codes are combinatorial objects which have traditionally been used to enhance the transmission of data on unreliable media. They have experienced a phenomenal growth since their birth some fifty years ago. Today, everyday tasks such as listening to a CD, accessing the hard disk of an electronic device, talking on a wireless phone, or downloading files from the Internet are impossible without the use of error-correcting codes. Though traditional communication still occupies centerstage in the realm of applied coding theory, emerging applications are changing the rules of the game, and calling for a new type of coding theory capable of addressing future needs. These are not limited to physical applications, however. In fact, coding theory is an integral part of solutions offered by researchers outside traditional physical communication to solve fundamental problems of interest, such as the complexity of computation, reliable transfer of bulk data, cryptographic protocols, self correcting software, signal processing, or even computational biology.While research in the past fifty years has put traditional coding theory on firm theoretical grounds, emerging applications are in need of new tools and methods to design, analyze, and implement coding technologies capable of dealing with future needs. This is the main concern of the present proposal. To strike the right balance between length and impact we have identified five areas of research that span the full spectrum of coding theory ranging from fundamental theoretical aspects to practical applications. We set out to develop new theoretical and practical models for the design and analysis of codes, and explore new application areas hitherto untouched. A unique feature of this proposal is our choice of the tools, ranging from classical areas of algebra, combinatorics, and probability theory, to ideas and methods from theoretical computer science.

Project Evolution of Development In Plants
Researcher (PI) Jane Alison Langdale
Host Institution (HI) THE CHANCELLOR, MASTERS AND SCHOLARS OF THE UNIVERSITY OF OXFORD
Call Details Advanced Grant (AdG), LS3, ERC-2008-AdG
Summary Different morphologies evolve in different organisms in response to changing environments. As land plants evolved, developmental mechanisms were either generated de novo, or were recruited from existing toolkits and adapted to facilitate changes in form. Some of these changes occurred once, others on multiple occasions, and others were gained and then subsequently lost in a subset of lineages. Why have certain forms survived and others not? Why does a fern look different from a flowering plant, and why should developmental biologists care? By determining how many different ways there are to generate a particular morphology, we gain an understanding of whether a particular transition is constrained. This basic information allows an assessment of the extent to which genetic variation can modify developmental mechanisms and an indication of the degree of developmental plasticity that is possible and/or tolerated both within and between species. This proposal aims to characterize the developmental mechanisms that underpin the diverse shoot forms seen in extant plant species. The main goal is to compare developmental mechanisms that operate in vegetative shoots of bryophytes, lycophytes, ferns and angiosperms, with a view to understanding the constraints that limit morphological variation. Specifically, we will investigate the developmental basis of three major innovations that altered the morphology of vegetative shoots during land plant evolution: 1) formation of a multi-cellular embryo; 2) organization of apical growth centres and 3) patterning of leaves in distinct spatial arrangements along the shoot. To facilitate progress we also aim to develop transgenic methods, create mutant populations and generate digital transcriptomes for model species at key phylogenetic nodes. The proposed work will generate scenarios to explain how land plant form evolved and perhaps more importantly, how it could change in the future.

Summary We propose the development of new electrochemical techniques for health and life sciences applications in Lab-on-a-Chip devices. A Scanning ElectroChemical Microscope (SECM) will be used to study surface properties, such as local consumption and/or release of electroactive chemical compounds by (single) cells by electrochemical sensing, new detection methods for proteins using redox cycling, and new separation methods for DNA exploiting nanoscale electrical field gradients. The ability to generate and control electrical fields (and gradients) at the scale of the size of biomolecules using nanostructures, and the simple translation of novel electrical methods into practical Lab-on-a-Chip devices will create a breakthrough in bioanalytical methods. The knowledge and expertise obtained from SECM experimentation will be used to design and realize Labs-on-a-Chip that can be used for efficient production of drugs by electrofused cells, for early biomarker detection using nanowires and nano-spaced electrodes (Point-of-Care application), and rapid DNA analysis using nanofluidic structures. Besides this, the results can have great benefits for study of embryonic cell growth and for advanced tissue engineering. The results will be translated into devices and systems that can be used in Point-of-Care (POC) applications and will bring this area a big step closer to successful commercialization.

Summary The project is multi-disciplinary by character. It focuses upon socio-historical processes of the transformation and 'circulation' of educated and ruling elites in several uniquely composite (both multi-ethnic and multi-confessional) East European regional or national societies, having experienced a number of radical changes of social and political regime as well as state souvereignty in the first half of the 20th century. The historical scope of the study extends from post-feudalism to communism. Societies involved comprise Hungary, Slovakia, Transylvania, Voivodina in the Carpathian Basin, Latvia and Estonia in the Baltics. The study draws upon sociological survey methods applied to historically successive elite brackets in form of exhaustive or quasi-exhaustive computerized prosopographical data banks, based on standardized individual biographies of elite members (as permitted by mostly archival sources to be exploited). The main targets would include secondary school graduates, students and graduates of higher education, the main intellectual professions (like doctors and lawyers.), the political power elites as well as 'reputational elites' - those cited in biographical dictionaries. The information fed into our data banks help to clarify thanks to various procedures of multi-variate statistical schemes the contrasting socio-cultural selection and recruitment of elite members, their educational path from primary to higher education, their professional career, intellectual creativity as well as socio-political standing and orientation. This is the first time that large region- or country-wide elite clusters are submitted to systematic socio-historical analyses, covering simultaneously all or most markets of activity and self-assertion of educated clusters in a vast international and comparative perspective related to culturally composite societal formations.

Host Institution (HI) POLITECNICO DI MILANO
Call Details Advanced Grant (AdG), PE2, ERC-2008-AdG
Summary The target of the proposal is the first experimental demonstration of attosecond coherent control of electron motion in many-particle systems. The past decade has seen remarkable advances in the field of coherent control of chemical reactions thanks to the application of femtosecond technology; I propose to use the emerging attosecond technology to achieve coherent control of photodissociation reactions on a purely electronic scale. I will mainly concentrate on molecules with biological interest. The success of the project will be based on the possibility to initiate and control the sub-femtosecond electronic motion in large molecules, by using high-intensity isolated attosecond pulses. Such electron motion precedes and determines the subsequent nuclear rearrangement, which ultimately leads to the chemical change. In this way it will be possible to control in a direct way the outcome of a chemical reaction, which is one of the central problems in modern chemistry. A crucial benchmark of the project, substantially beyond the current state-of-the-art in Attosecond Science, will be the experimental demonstration of attosecond pump / attosecond-probe measurements, which for the present are not technically feasible. Electron dynamics will be measured, with attosecond resolution, in many-particle systems, ranging from simple molecules to complex bio-molecules.
The application of attosecond pulses and the development of attochemistry techniques for the investigation of the primary electronic steps of chemical processes, is a completely new and challenging research field, with tremendous prospects for both fundamental research and technology. In particular, the attosecond coherent control of charge localization in bio-molecules can offer unique information on the mechanisms at the basis of biological signal transmission or on the processes leading to damaging of complex biological molecules (from polypeptides to proteins and DNA).

Project An Intense Summer Monsoon in a Cool World, Climate and East Asian Monsoon during Interglacials with a special emphasis on the Interglacials 500,000 years ago and before
Researcher (PI) André, Léon Berger
Host Institution (HI) UNIVERSITE CATHOLIQUE DE LOUVAIN
Call Details Advanced Grant (AdG), PE10, ERC-2008-AdG
Summary Asian monsoon is a spectacular occurrence in the climate system. What make it so powerful are the combination of thermal contrast between the World s largest landmass (Eurasian continent) and ocean basin (the Indo-Pacific Ocean) and the presence of the World s largest ridge, the Tibetan Plateau. Climatologically, monsoon regions are the most convectively active areas and account for the majority of global atmospheric heat and moisture transport. Moreover, the economy, culture and rhythms of life of 60% of humanity are critically influenced by the evolution and variability of the Asian monsoon. The need to better understand the monsoon leads inevitably to the close inspection of its activity during the geological times to provide a long-term perspective from which any future change may be more effectively assessed. Our research proposal aims to understand the seeming paradox of the exceptionally intense East Asian summer monsoon (actually the strongest over the last one million years) which occurred during the relatively cool interglacial (MIS-13), 500,000 years ago. This will be done using first a model of intermediate complexity (LOVECLIM) to achieve a number of sensitivity experiments to the astronomical forcing, the Eurasian and North American ice sheets, the Tibetan Plateau and the Ocean. Ocean-atmosphere coupled general circulation models will then be used to confirm the main processes underlined by LOVECLIM, in particular those related to the wave train topographically induced by the Eurasian ice sheet, to the Tibetan Plateau, to the sea-surface temperature and to their role in reinforcing the East Asian summer monsoon. This monsoon of MIS-13 will be compared with the monsoon which occurred during the other interglacials of the upper Pleistocene and Holocene (about the last 700,000 years). All simulation results will be compared with the available proxy records, in particular-but not exclusively-those coming from the loess-soil sequences in China.

Researcher (PI) Angelos Chaniotis
Host Institution (HI) THE CHANCELLOR, MASTERS AND SCHOLARS OF THE UNIVERSITY OF OXFORD
Call Details Advanced Grant (AdG), SH6, ERC-2008-AdG
Summary Emotions influence social relations; consequently, they are socially relevant, subject to scrutiny, judgment, and normative intervention. The manifestation, perception and treatment of emotions are subject to social interventions and to the influence of cultural change. Emotions in the Classical world have been primarily studied in the light of their representation in literature and art. Such studies have provided important insights; yet, they are based on works primarily created in a few major urban centres, almost exclusively by educated men of a higher status. This project is based on an analysis of documentary sources (inscriptions and papyri, c. 800 BC-c. 500 AD). Although they provide abundant, diverse, and representative evidence, they have never been studied in connection with this subject. As compared to literature and art, these sources represent a wide range of social strata and age-classes, originate in both genders, and are widely disseminated over time and space. These sources will be analysed both diachronically (history of particular emotions) and synchronically (manifestations of emotions in defined historical contexts). Selected literary sources and archaeological material will also be taken into consideration. The project pursues the following objectives: to contribute to a more reliable, nuanced, and comprehensive history of emotions in the Greek world; to increase awareness of the importance of emotions in Classical studies; to contribute to the transdisciplinary study of emotions through the presentation of paradigms from Classical antiquity; to enhance the dialogue between historical, social, and natural sciences; and to make documentary sources accessible to scholars working on the history of emotions and, more generally, on the history of mentality.

Project Balkan Histories: Shared, Connected, Entangled
Researcher (PI) Roumen Daskalov
Host Institution (HI) NEW BULGARIAN UNIVERSITY
Call Details Advanced Grant (AdG), SH6, ERC-2008-AdG
Summary THE OBJECTIVE of this project is to explore the various ways in which the histories of the Balkan peoples were shared, connected and entangled, and in some cases became structurally inter-dependent in the course of the nineteenth and the twentieth centuries; also to explore transfers and crossings within the region and from Western Europe and Russia. What is offered is a provisional open-ended and long-term research program guided by a general paradigm , frame of reference and key concepts. I would rather keep the project open and flexible with regard to substantial issues, though with a clear vision of the general (transnational) perspective. A list of topics includes national and social movements, disputed territories, minorities and refugees, cultural and political transfers. The variegated topics demand expertise in different areas and a trans-disciplinary and inter-disciplinary treatment without regard to established disciplinary boundaries. Systematically applying the transnational and relational perspective to the study of a region as complex as the Balkans has huge cognitive potential and innovative power. The new perspective and cutting-edge methodologies will reveal fresh vistas and bring insights to a number of topics that cannot be restricted in advance. Older research objects will look different and acquire new meanings in the new context and entirely new historical objects will be constituted. The national paradigm of self-contained national histories will be challenged. Such a project may well have wider social and political relevance. There is a positive and integrative value in showing how entangled the histories of the present-day Balkan nations and states were and still are. I would like to imagine such research as promoting good relations rather than fostering divisiveness and separation. This project will also be an input to the European integration of the region, which will hopefully involve the rest of the Balkans in the near future.

Project Dissection of environmentally-mediated epigenetic silencing
Researcher (PI) Caroline Dean
Host Institution (HI) JOHN INNES CENTRE
Call Details Advanced Grant (AdG), LS2, ERC-2008-AdG
Summary We intend to achieve a step change in our understanding of the mechanistic basis of epigenetic regulation. We will capitalize on a plant epigenetic silencing system, vernalization, which has many features that allow the complete dissection of different facets of epigenetic regulation. In addition, the silencing is quantitatively modulated by the environment enabling dissection of how external cues mediate epigenetic silencing. We will combine genetics, molecular biology and biochemical approaches with computational modelling to allow us to translate the extensive nuts and bolts information into an understanding of how the engine works. A particular strength of modelling will be its predictive nature and ability to distinguish between key components and those with subsidiary or redundant roles. The system we will use is vernalization, the cold-induced Polycomb-silencing of the target locus, FLC. We will dissect the many phases of vernalization: the triggering of FLC repression by prolonged cold; the nucleation and epigenetic stability of chromatin changes at FLC; and the spreading of the silencing yet spatial restriction to FLC. Our goal will be a full understanding of the complexity involved in the epigenetic silencing of this locus, described in a quantitative model that reveals how the silencing is induced by temperature and how individual components of the silencing network are integrated into a robust whole. This ambitious goal, which will uncover fundamental concepts important to gene regulation in many organisms, will be achieved through a tight integration of molecular analysis and computational modelling, enabling efficient cycling between experimentation, prediction and validation.

Host Institution (HI) HELSINGIN YLIOPISTO
Call Details Advanced Grant (AdG), LS7, ERC-2008-AdG
Summary Early detection is crucial for the outcome of most cancers. Prevention of cancer development is even more desirable. To facilitate these ultimate goals we aim to construct a comprehensive view of the stepwise process through which common human cancers, such as colorectal cancer, arise. In particular, we aim to identify novel mechanisms of cancer susceptibility by focusing on the epigenome, whose alterations may underlie several phenomena related to chronic adult-onset disease that are not explained by genetics alone. The stepwise process of carcinogenesis can be accelerated or halted for various reasons, including inherited susceptibility and diet. The human multi-organ cancer syndromes hereditary nonpolyposis colorectal cancer (HNPCC) and familial adenomatous polyposis (FAP) as well as their murine counterparts, the Mlh1+/- mouse and the ApcMin/+ mouse, will be used as shortcuts to study the interplay between the epigenome and genome in tumorigenesis and to identify biomarkers of cancer susceptibility, malignant transformation, and tumor progression. This will be achieved by molecular profiling of normal and tumor tissues, cell line studies, in vitro functional assays, and in silico approaches. Additionally, the role that the epigenome plays to mediate the effects of the Western type diet on colorectal tumorigenesis will be examined in the mouse. Unlike genetic changes, epigenetic alterations are potentially reversible, which makes them promising targets for preventive and therapeutic interventions.

The human multi-organ cancer syndromes hereditary nonpolyposis colorectal cancer (HNPCC) and familial adenomatous polyposis (FAP) as well as their murine counterparts, the Mlh1+/- mouse and the ApcMin/+ mouse, will be used as shortcuts to study the interplay between the epigenome and genome in tumorigenesis and to identify biomarkers of cancer susceptibility, malignant transformation, and tumor progression. This will be achieved by molecular profiling of normal and tumor tissues, cell line studies, in vitro functional assays, and in silico approaches. Additionally, the role that the epigenome plays to mediate the effects of the Western type diet on colorectal tumorigenesis will be examined in the mouse. Unlike genetic changes, epigenetic alterations are potentially reversible, which makes them promising targets for preventive and therapeutic interventions.

Project acronym EQUIARITH
Project Equidistribution in number theory

Host Institution (HI) ECOLE POLYTECHNIQUE FEDERALE DE LAUSANNE
Call Details Advanced Grant (AdG), PE1, ERC-2008-AdG
Summary The purpose of this proposal is to investigate from various perspectives some equidistribution problems associated with homogeneous spaces of arithmetic type: a typical problem (basically solved) is the distribution of the set of representations of a large integer by an integral quadratic form. Another harder problem is the study of the distribution of special points on Shimura varieties. In a different direction (linked with quantum chaos), the study of the concentration of Laplacian (Maass) eigenforms or of sections of holomorphic bundles is related to similar problems. Given X such a space and G>L the underlying algebraic group and its corresponding lattice L, the above questions boil down to studying the distribution of H-orbits x.H (or more generally H-invariant measures)on the quotient L\G for some subgroups H. This question may be studied different methods: Harmonic Analysis (HA): given a function f on L\G one studies the period integral of f along x.H. This may be done by automorphic methods. In favorable circumstances, the above periods are related to L-functions which one may hope to treat by methods from analytic number theory (the subconvexity problem). Ergodic Theory (ET): one studies the properties of weak*-limits of the measures supported by x.H using rigidity techniques: depending on the nature of H, one might use either rigidity of unipotent actions or the more recent rigidity results for torus actions in rank >1. In fact, HA and ET are intertwined and complementary : the use of ET in this context require a substantial input from number theory and HA, while ET lead to a soft understanding of several features of HA. In addition, the Langlands correspondence principle make it possible to pass from one group G to another. Based on earlier experience, our goal is to develop these interactions systematically and to develop new approaches to outstanding arithmetic problems :eg. the subconvexity problem or the Andre/Oort conjecture.

Researcher (PI) Bo Stråth
Host Institution (HI) HELSINGIN YLIOPISTO
Call Details Advanced Grant (AdG), SH2, ERC-2008-AdG
Summary The point of departure of this project is that a good part of the present deficit of legitimacy of European institutions emerges from a deeply ahistoric view of Europe s past. Consequently, there is an urgent need for a more realistic history that rejects any teleological understanding of Europe as a self-propelling project on steady march towards a predetermined goal. The fragility of European peace and progress needs to be highlighted. The theoretical foundation of Europe in teleological modernisation and globalisation theories has lead to a-historical understandings of Europe s past that disturb our ability to plan for its future. Our realistic outline of Europe s past focuses on the century 1815-1914, which was the pre-war historical ground on which the peace of 1945 and our present conception of Europe were built. It testifies at least as much to conflict and fragility as to progress. The century is traversed by a series of tensions in the political, cultural, social, economic and legal fields and struggles between the protagonists of different conceptions of European modernity. The legal and political basis for a new European order established in the Vienna Treaty, called the European concert, opened an era that lasted until 1914 in which wars in Europe decreased, whereas the number of civil wars increased and the Revolution came to no end. The tensions were articulated in different geopolitical strategies, constitutional conceptions, prescriptions for economic efficiency and claims for social protection, and alternating views of the meaning of Europe. In one way or the other, they all dealt with the interactive dynamics between politics and law, nationally as well as internationally. These interactive dynamics were also visible in the permanent movement between search for and expectations of stability and experiences of fragility. The aim is to explore the tensions in deep detail and on that basis build an alternative historical view on Europe.

Summary Our objective is to develop and apply a novel methodology to understand better EU research system dynamics and the European Research Council’s activities by assessing its funding schemes’ impact and outcomes. We will report on robustly measured, properly attributed impacts for: researchers (starting/advanced); the organisation of research; and science governance (national/transnational funding agencies, science policies). We have conceptualised how research communities, organisations and funders operate. Our robust, flexible methodology assumes to register impact by measurement of at least two time points and gives serious consideration to attribution issues. Our team members have international reputations in science studies, research intermediaries, science governance, organisational analysis, and methodology. We aim to: develop a framework to analyse ERC funding scheme impact(s) and interactions with existing governance regimes; develop a method to identify and attribute ERC impacts; apply this method (to test it and to collect Phase 1 data on a) researchers b) research organisations c) research funding organisations and d) the wider national/transnational science governance context); propose methodologies for discrete (panel) to assess progress towards the ERC’s desired/expected outcomes and impact; ensure our framework has a statement (and understanding) of ‘added value’; and aid ERC’s strategy (including scrutinising its objectives) in consultation with key stakeholders. Our research activities are: a ‘starting independent researchers’ survey; ‘starting independent researchers’/‘advanced investigators’ studies; host research organisation case studies; national research council (or equivalent) case studies; and ERC and EU funding landscape review. Our 9 WPs provide for in-built interactions between activities.

Call Details Advanced Grant (AdG), SH5, ERC-2008-AdG
Summary During the last three decades, Islam has gained visibility in European public spheres through new religious symbols, but as well as new public figures, men and women, pious and secular who carry Islam in European public life. Islamic entry in the public sphere, and the claims for religious visibility provoke a series of debates on gender equality, freedom of expression and cultural (civilisational) differences in European publics. EUROPUBLICISLAM sets itself the intellectual research agenda of bringing together different fields of knowledge and analysis of the transformative forces that appear in the contemporary meeting of Islam and Europe. It proposes to develop an innovative understanding of the sporadic and at times violent ways in which Islam intervenes in the making of the European public sphere. EUROPUBLICISLAM engages with the European scholarly agenda on migration, the construction of a European public sphere, and Islam. It aims at shifting the contemporary theorization of Islam in Europe away from the integration and security paradigms, and towards a new theory of dynamics of interaction and mutual change. A new research field is marked out in combining and transforming the contemporary theorizations of European public sphere and European Islam. EUROPUBLICISLAM proposes to study religious symbols, artistic cultural productions and public figures affecting the everyday politics of cultural discord. It aims to re-conceptualize the place of Islam in the making of a European public sphere. An innovative methodology is proposed to study the constellations , the assemblages that bring together cultural differences in proximity and in confrontation across national public spheres, following a transnational dynamics. EUROPUBLICISLAM will thus contribute to the production of innovative research on the making and imaging a European public sphere where transformative cultural and aesthetic mixes and thus political pluralism are taking place.

Project The Evolution of Culture

Host Institution (HI) THE UNIVERSITY COURT OF THE UNIVERSITY OF ST ANDREWS
Call Details Advanced Grant (AdG), LS8, ERC-2008-AdG
Summary The capacity for culture is clearly a critical factor underlying the success of our species, but how and why did it evolve? What are the selection pressures that favoured the evolution of cultural capabilities (e.g. social learning, innovation, teaching), and how has selection fashioned these to operate efficiently? The study of such abilities is central to a broad range of disciplines, and significant progress in the scientific understanding of their origin and operation will ripple out to exert considerable influence, both within and outside academia. This project utilises a broad but integrated package of highly innovative empirical and theoretical techniques, including the development of novel analytical tools that allow behavioural researchers to identify social learning and predict the diffusion of innovations, application of potentially revolutionary statistical methods for inferring causal influences on the evolution of brain and culture from correlational data, and a new empirical system providing an unparalleled opportunity to investigate the evolution and biological basis of social learning. I will also organize international competitions to identify effective social learning rules ( tournaments ), in which entrants each propose learning strategies that are pitted against each other in computer simulation, and the most effective wins a prize. Collectively, the projects offer a major step forward in our understanding of human evolution, adaptation and culture and will stimulate considerable interdisciplinary exchange.

Summary Expander graphs are finite graphs which play a fundamental role in many areas of computer science such as: communication networks, algorithms and more. Several areas of deep mathematics have been used in order to give explicit constructions of such graphs e.g. Kazhdan property (T) from representation theory of semisimple Lie groups, Ramanujan conjecture from the theory of automorphic forms and more. In recent years, computer science has started to pay its debt to mathematics: expander graphs are playing an increasing role in several areas of pure mathematics. The goal of the current research plan is to deepen these connections in both directions with special emphasis of the more recent and surprising application of expanders to group theory, the geometry of 3-manifolds and number theory.

Host Institution (HI) UNIVERSITE DE PAU ET DES PAYS DE L'ADOUR
Call Details Advanced Grant (AdG), PE8, ERC-2008-AdG
Summary This project focuses on fluid flow in porous materials with evolving microstructure in the context of civil engineering applications and geomechanics. When the distribution of cracks and the distribution of pore size evolve in concrete and rocks, the influence on the permeability in the case of a single or a multiphase fluid flow needs some in depth investigation. A recent review of state of the art in modelling progressive mechanical breakdown and associated fluid flow in heterogeneous rock shows that little is known on the coupled effects between micro cracking and the intrinsic permeability of a solid phase. The present project intends to tackle this relationship between mechanical breakdown and associated fluid flow in the context of poromechanics extended to non local modelling. In particular, we will investigate how the internal length which plays a pivotal role at the inception and propagation of material failure may interact with the permeability, what enhanced Darcy-like relationship might be derived in order to apprehend such effects and how to model fluid flow in tight porous materials. The models will be extended to complex and multicomponent systems reproducing as closely as possible the behaviour of real fluids in order to understand and to describe the thermodynamical behaviour due to confinement such as modification of phase transitions and capillary condensation. The principal investigator of this project is a specialist in the field of continuum damage mechanics, failure due to strain and damage localisation. He has been the founder and among the major promoters of non local damage modelling, which is today a state of the art model in computational structural failure analyses. After a decade of research on durability problems for which he was elected at Institut Universitaire de France, his research interests recently turned toward petroleum engineering, the focus of the research team he joined two years ago at université de Pau.

Call Details Advanced Grant (AdG), PE2, ERC-2008-AdG
Summary The complex interplay between Coulomb repulsion and Fermi statistics in two dimensional systems is responsible for some of the most dramatic phenomena encountered in solid state physics (High critical temperature superfluidity, Fractional Quantum Hall Effect,..). However, despite decades of efforts, many questions regarding these systems are still unsolved. In FERLODIM, we plan to take advantage of recent progress in ultracold gases, to simulate several fundamental Hamiltonians describing these many-body systems in 1 and 2 dimensions. We will realize two ultra-cold atom machines allowing for a full characterization of the many-body wave function of an ensemble of interacting fermions in periodic potentials, called optical lattices. Our experiments will rely on a high resolution imaging system allowing both for single atom detection and the possibility of tailoring optical potentials of arbitrary shape and geometry. This unique design will allow us to address a variety of physical situations, depending on the geometry of the light induced potentials. One-dimensional problems will be addressed, from spin chains to Luttinger liquids. In pure two dimensional configurations, we will investigate the link between the repulsive Hubbard model, superfluidity and the Mott insulator transition, as well as frustration effects in periodic potentials. Finally we will explore the physics of interacting fermions under rotation in the lowest Landau level, and the connection with fractional Quantum Hall systems.

Host Institution (HI) EIDGENOESSISCHE TECHNISCHE HOCHSCHULE ZUERICH
Call Details Advanced Grant (AdG), PE1, ERC-2008-AdG
Summary Since the pioneering works of Black & Scholes, Merton and Markowitch, sophisticated quantitative methods are being used to introduce more complex financial products each year. However, this exciting increase in the complexity forces the industry to engage in proper risk management practices. The recent financial crisis emanating from risky loan practices is a prime example of this acute need. This proposal focuses exactly on this general problem. We will develop mathematical techniques to measure and assess the financial risk of new instruments. In the theoretical direction, we will expand the scope of recent studies on risk measures of Artzner et-al., and the stochastic representation formulae proved by the principal investigator and his collaborators. The core research team consists of mathematicians and the finance faculty. The newly created state-of-the-art finance laboratory at the host institution will have direct access to financial data. Moreover, executive education that is performed in this unit enables the research group to have close contacts with high level executives of the financial industry. The theoretical side of the project focuses on nonlinear partial differential equations (PDE), backward stochastic differential equations (BSDE) and dynamic risk measures. Already a deep connection between BSDEs and dynamic risk measures is developed by Peng, Delbaen and collaborators. Also, the principal investigator and his collaborators developed connections to PDEs. In this project, we further investigate these connections. Chief goals of this project are theoretical results and computational techniques in the general areas of BSDEs, fully nonlinear PDEs, and the development of risk management practices that are acceptable by the industry. The composition of the research team and our expertise in quantitative methods, well position us to effectively formulate and study theoretical problems with financial impact.

Call Details Advanced Grant (AdG), LS2, ERC-2008-AdG
Summary Polycomb group (PcG) and trithorax group (trxG) genes were discovered in Drosophila melanogaster as repressors and activators of Hox genes, a set of transcription factors that specify the antero-posterior axis of the body plan. PcG and trxG proteins form multimeric complexes that are required to maintain their expression state after the initial transcriptional regulators disappear from the embryo. Subsequent work led to a better understanding of their mechanisms of action. Moreover, PcG and trxG genes have also been identified in vertebrates, where they regulate Hox genes, they are involved in cell proliferation, stem cell identity and cancer, genomic imprinting in plants and mammals and X inactivation. PcG and trxG components form multimeric complexes. Some trxG and PcG components possess methyltransferase activities directed toward specific lysines of histone H3, whereas other trxG and PcG proteins interpret these histone marks. Recent studies have described the genomewide distribution of PcG proteins and of their related histone modification in Drosophila and other species. However, the PcG recruitment code to their target chromatin is still not understood, and the mechanism of PcG-mediated gene silencing is unclear. The formation of subnuclear silencing compartments might contribute to the stable repression of transcription. Drosophila PcG proteins have a speckled nuclear distribution and the number of these so-called PcG bodies is progressively reduced during development. We showed that multiple PREs can associate in the nucleus to enhance the strength of PcG-mediated silencing. However, we do not know how frequent is this clustering process and how important it is functionally at a genomewide level. Our project will tackle these questions by using a combination of genetics, developmental biology, cell biology, genomics and bioinformatic approaches, with the aim to gain an integrated understanding of the role of Polycomb and trithorax in biology

Summary Since the nineteenth century, the reinforced concrete has been generating a vast specialized litterature everywhere in the world. However, none of it has ever tried to make a first assessment of the evolution of one of the most fundamental element in the processing of the reinforced concrete: the formwork; nor have been reconstructed the various ways of processing the surfaces after removal of the formwork in order to get special effects of polished or rustic surface. Therefore, on the subject of manufacturing of the formworks and processing of the surface, there is a true gap in the studies on reinforced concrete that the research The surfaces of cement and reinforced concrete. A history of the formworks and processing of the surface, 1870-2008 intends to fill. Whether historical or operationnal, this gap lacks not only of the context of the evolution from the nineteenth century, but also of a comprehensive outline of the recent production. The purpose of the research is to provide the most comprehensive documentation and the most significant examples of the international architectural production on the subject of formworks and concrete surfaces within the time span considered. Drawing up the outline of the various types of building and processing of the surfaces will be extraordinarily useful for the historiography of architecture, which will hence have a scientific instrument to evaluate the works in terms of connections between form and material in relation to concrete, as well as for the modern formworks in which the technicial and artistical issues of reinforced concrete processing at sight still remain fundamental. The results of the research will be collected in a book with the caracteristics of an essay, consisting of an important written part and an extremely rich iconographic documentation (project drawings, photographs of building sites and tools, etc.); it will be structured as a synthesis between the technical manual and the historical critical essay.

Project Statistics of Fractionally Charged Quasi-Particles

Host Institution (HI) WEIZMANN INSTITUTE OF SCIENCE
Call Details Advanced Grant (AdG), PE3, ERC-2008-AdG
Summary The discovery of the fractional quantum Hall effect created a revolution in solid state research by introducing a new state of matter resulting from strong electron interactions. The new state is characterized by excitations (quasi-particles) that carry fractional charge, which are expected to obey fractional statistics. While odd denominator fractional states are expected to have an abelian statistics, the newly discovered 5/2 even denominator fractional state is expected to have a non-abelian statistics. Moreover, a large number of emerging proposals predict that the latter state can be employed for topological quantum computing ( Station Q was founded by Microsoft Corp. in order to pursue this goal). This proposal aims at studying the abelian and non-abelian fractional charges, and in particular to observe their peculiar statistics. While charges are preferably determined by measuring quantum shot noise, their statistics must be determined via interference experiments, where one particle goes around another. The experiments are very demanding since the even denominator fractions turn to be very fragile and thus can be observed only in the purest possible two dimensional electron gas and at the lowest temperatures. While until very recently such high quality samples were available only by a single grower (in the USA), we have the capability now to grow extremely pure samples with profound even denominator states. As will be detailed in the proposal, we have all the necessary tools to study charge and statistics of these fascinating excitations, due to our experience in crystal growth, shot noise and interferometry measurements.

Call Details Advanced Grant (AdG), PE1, ERC-2008-AdG
Summary The basic idea of the project is to apply methods and results of the theory of integrable systems to non-integrable PDEs. We do not promise to solve any PDE; however, in certain strongly nonlinear regimes, solutions to a conservative non-integrable PDE exhibit integrable behaviour. The realization of this idea, supported by some preliminary analytical and numerical results, will consist of three main tasks: 1) classify normal forms of quasilinear Hamiltonian PDEs and their perturbations; 2) reduce the lists of asymptotic solutions to an abridged list of universal forms represented via Painlevé transcendents, theta-functions, etc.; 3) establish matching rules between the universal asymptotic expansions. Differential-geometric methods based on the theory of Frobenius manifolds will be crucial in solving the classification problems; analytic and algebro-geometric techniques applied to the Hurwitz spaces of Riemann surfaces will be instrumental in the description of nonlinear oscillatory regimes; selected solutions to Painlevé equations and their generalizations will be needed for the analytic description of transitions from regular to oscillatory behaviour. The project is aiming at creation of an online library of the main qualitative types of behaviour of solutions to large classes of nonlinear evolutionary PDEs supplied with analytic expressions, numerical codes and visualization tools, as well as with tests of existence of a Hamiltonian structure, integrability or almost integrability. Such a library will both stimulate the research in the field and lead to a high visibility of the project.

Summary How does information processing in neural circuits generate behaviour? Answering this question requires identifying each of the distinct neuronal types that contributes to a behaviour, defining their anatomy and connectivity, and establishing causal relationships between their activity, the activity of other neurons in the circuit, and the behaviour. Here, I propose such an analysis of the neural circuits that guide Drosophila mating behaviours. The distinct mating behaviours of males and females are genetically pre-programmed, yet can also be modified by experience. The set of ~2000 neurons that express the fru gene have been intimately linked to both male and female mating behaviours. This set of neurons includes specific sensory, central, and motor neurons, at least some of which are directly connected. Male-specific fruM isoforms configure this circuit developmentally for male rather than female behaviour. In females, mating triggers a biochemical cascade that reconfigures the circuit for post-mating rather than virgin female behaviour. We estimate that there are ~100 distinct classes of fru neuron. Using genetic and optical tools, we aim to identify each distinct class of fru neuron and to define its anatomy and connectivity. By silencing or activating specific neurons, or changing their genetic sex, we will assess their contributions to male and female behaviours, and how these perturbations impinge on activity patterns in other fru neurons. We also aim to define how a specific experience can modify the physiological properties of these circuits, and how these changes in turn modulate mating behaviour. These studies will define the operating principles of these neural circuits, contributing to a molecules-to-systems explanation of Drosophila s mating behaviours.

Call Details Advanced Grant (AdG), LS9, ERC-2008-AdG
Summary "FUEL-PATH aims at providing new knowledge on plant cell wall and innovative biotechnological solutions for biomass utilization. A key process for biomass utilization is the initial degradation of cell walls into fermentable sugars (saccharification); this is hindered by the wall recalcitrance to hydrolysis. We propose to improve the plant saccharification characteristics by mimicking a strategy successfully used by phytopathogenic microorganisms. These produce pectic enzymes before other cell wall-degrading enzymes (CWDEs) to weaken the linkages between the wall components and favour the maceration of the plant tissue. Homogalacturonan (HGA), a major component of pectin, is synthesized in a methylated form and is de-esterified in the wall by methylesterases (PMEs). De-esterified HGA interacts with calcium to form ""egg-box"" structures, which are critical for maintaining the integrity of the entire wall. We propose to improve saccharification by expression in plants of microbial polygalacturonases (PGs) hydrolizing HGA. Plants expressing a fungal PG have reduced levels of HGA and enhanced saccharification (unpublished preliminary data). Since PG activity in pianta affects normal growth, a technology of enzyme control through the use of specific protein inhibitors will be developed. A second strategy to be adopted for weakening the ""egg-box"" is the overexpression of PME inhibitors. This may cause not only an increased degradability but also an enhanced biomass production. FUEL-PATH will provide detailed information on the structure, function and construction of tailor-made enzymes and inhibitors suitable for the saccharification process. FUEL-PATH will also address the relationship between pectin composition and developmental responses mediated by hormones in PG-expressing plants. A genetic screen will be performed to isolate genes involved growth defects and increased cell wall degradability and these will be characterized for a possible biotechnological use."

Summary The area of catalysis is now at the forefront of the chemical sciences in light of environmental and economic issues. Synthesizing bulk, fine and pharmaceutical compounds using catalysis is now a must in the modern economy. The studies described in the present proposal make use of the full arsenal of techniques available for modern synthetic chemical investigation: fundamental physicochemical studies, experiment-based rational catalyst design and catalytic studies. The exploratory physicochemical experiments to be performed make use of classical solution reaction calorimetry involving air- and moisture sensitive complexes. This area is very poorly investigated worldwide. The PI is a world leader in the area of organometallic thermochemistry, a technique that is proposed for elaboration in Spain. This section of the proposal will permit an increase of knowledge on fundamental catalytic systems, allowing for determination of enthalpy and kinetics of key reaction steps involved in homogeneous catalysis. Much needed thermodynamic information will be generated for palladium, gold, iridium and rhenium systems. The development of a rhenium-based system is proposed for investigation in the area of olefin metathesis. Furthermore, ruthenium-systems enabling alkyne metathesis are targeted for synthesis. The development of such olefin modifying system would greatly benefit Europe as catalytic transformations have huge potential in polymer, pharmaceutical and fine chemical industries. The proposed work is both fundamental and applied high risk and high reward. It is outside the presently investigated areas of research carried out by our group at the ICIQ. The Principal Investigator (PI) has 25 years of experience in fundamental and applied chemical research and 15 years of experience as an independent researcher in homogeneous catalysis and organometallic chemistry.

Summary Low-temperature studies of transition metal doped III-V and II-VI compounds carried out over the last decade have demonstrated the unprecedented opportunity offered by these systems for exploring physical phenomena and device concepts in previously unavailable combinations of quantum structures and ferromagnetism in semiconductors. The work proposed here aims at combining and at advancing epitaxial methods, spatially-resolved nano-characterisation tools, and theoretical modelling in order to understand the intricate interplay between carrier localisation, magnetism, and magnetic ion distribution in DMS, and to develop functional DMS structures. To accomplish these goals we will take advantage of two recent breakthroughs in materials engineering. First, the attainment of high-k oxides makes now possible to generate interfacial hole densities up to 10^21 cm-3. We will exploit gated thin layers of DMS phosphides, nitrides, and oxides, in which hole delocalization and thus high temperature ferromagnetism is to be expected under gate bias. Furthermore we will systematically investigate how the Curie temperature of (Ga,Mn)As can be risen above 180 K. Second, the progress in nanoscale chemical analysis has allowed demonstrating that high temperature ferromagnetism of semiconductors results from nanoscale crystallographic or chemical phase separations into regions containing a large concentration of the magnetic constituent. We will elaborate experimentally and theoretically epitaxy and co-doping protocols for controlling the self-organised growth of magnetic nanostructures, utilizing broadly synchrotron radiation and nanoscopic characterisation tools. The established methods will allow us to obtain on demand either magnetic nano-dots or magnetic nano-columns embedded in a semiconductor host, for which we predict, and will demonstrate, ground-breaking functionalities. We will also assess reports on the possibility of high-temperature ferromagnetism without magnetic ions.

Summary I aim to achieve a fundamental understanding of the atomistic kinetic pathways responsible for nanostructure formation and to explore the concept of self-organization by thermodynamic segregation in functional ceramics. Model systems are advanced ceramic thin films, which will be studied under two defining cases: 1) deposition of supersaturated solid solutions or nanocomposites by magnetron sputtering (epitaxy) and arc evaporation. 2) post-deposition annealing (ageing) of as-synthesized material. Thin film ceramics are terra incognita for compositions in the miscibility gap. The field is exciting since both surface and in-depth decomposition can take place in the alloys. The methodology is based on combined growth experiments, characterization, and ab initio calculations to identify and describe systems with a large miscibility gap. A hot topic is to elucidate the bonding nature of the cubic-SiNx interfacial phase, discovered by us in TiN/Si3N4 with impact for superhard nanocomposites. I have also pioneered studies of self-organization by spinodal decomposition in TiAlN alloy films (age hardening). Here, the details of metastable c-AlN nm domain formation are unknown and the systems HfAlN and ZrAlN are predicted to be even more promising. Other model systems are III-nitrides (band gap engineering), semiconductor/insulator oxides (interface conductivity) and carbides (tribology). The proposed research is exploratory and has the potential of explaining outstanding phenomena (Gibbs-Thomson effect, strain, and spinodal decomposition) as well as discovering new phases, for which my group has a track-record, backed-up by state-of-the-art in situ techniques. One can envision a new class of super-hard all-crystalline ceramic nanocomposites with relevance for a large number of research areas where elevated temperature is of concern, significant in impact for areas as diverse as microelectronics and cutting tools as well as mechanical and optical components.

Summary Based on our developments of Spin-Polarized Scanning Tunnelling Microscopy (SP-STM) and Magnetic Exchange Force Microscopy (MExFM), both offering spin sensitivity and spatial resolution down to the ultimate limit of single atoms, we will study spin-dependent interactions between individual magnetic atoms on metal surfaces, in diluted magnetic semiconductors, on surfaces of magnetic insulators, as well as between single-atom tips and ultracold quantum gases. Besides the investigation of static spin states and spin interactions, we will manipulate spin states in a controlled manner down to the single atom limit by making use of the spin-transfer torque exerted by spin-currents from an atomically sharp SP-STM tip across a vacuum barrier. Moreover, we will combine spin-current induced magnetization switching experiments on magnetic metallic nanostructures based on SP-STM with pump-probe experiments, thereby studying the fundamentals of magnetization reversal processes both spatially and time-resolved. We will make use of the powerful combination of SP-STM with single-atom manipulation to probe spin-dependent interactions in artificial nanostructures. In the case of magnetic insulators we will probe spin states and spin-dependent interactions based on local measurements of the quantum-mechanical exchange and correlation forces between a single-atom tip with a well-defined spin state and single atoms of the sample. Spin excitations at the level of individual atoms will be probed by a combination of SP-STM with inelastic electron tunnelling spectroscopy, while the combination of MExFM with measurements of the damping of the cantilever oscillation will be employed to reveal local spin excitations in electrically insulating materials. Finally, we will couple an MExFM-type force sensor to the spin state of an optically trapped ultracold quantum gas with the challenging goal to combine scanning probe and quantum optical methods for manipulating quantum states of matter.

Call Details Advanced Grant (AdG), SH3, ERC-2008-AdG
Summary This interdisciplinary project (combining social and earth sciences) addresses a key gap in the knowledge of global assessments concerning the likely consequences of future climate change on future human wellbeing. More information about the determinants of future adaptive capacity is necessary for setting policy priorities today: Should the significant funds allocated for adaptation be invested in enhancing existing infrastructure or currently practiced agricultural strategies (some of which may not be tenable under future climates), or should they invest alternatively in enhancing human empowerment through education and health which in consequence will enable affected societies to better cope with whatever challenges the future will bring? This study is expected to bring significant progress in this difficult multidisciplinary, yet highly relevant, field through a combination of: (a) New global science-based, long-term projections of human capital (population by age, sex and level of education) as a key element of adaptive capacity; (b) Three empirical multi-national studies on key factors involved in past vulnerability and adaptations to the Sahelian drought, Hurricane Mitch and the Asian tsunami; (c) Three prospective case studies assessing future adaptive capacity for the Phuket region, Mauritius and the Nicobar islands; (d) All held together and put into perspective by the elaboration of a new demographic theory of long-term social change with predictive power. This rather complex project structure is necessary for reaching generalizable and useful results. All components have been designed to complement each other to maximize the chances of achieving path-breaking and at the same time tangible results in this highly complex, multidisciplinary field. All components of the study will build on previous work of IIASA and Wolfgang Lutz and hence minimize the need to acquire additional experience for the case study sites or for the methodology used.

This study is expected to bring significant progress in this difficult multidisciplinary, yet highly relevant, field through a combination of: (a) New global science-based, long-term projections of human capital (population by age, sex and level of education) as a key element of adaptive capacity; (b) Three empirical multi-national studies on key factors involved in past vulnerability and adaptations to the Sahelian drought, Hurricane Mitch and the Asian tsunami; (c) Three prospective case studies assessing future adaptive capacity for the Phuket region, Mauritius and the Nicobar islands; (d) All held together and put into perspective by the elaboration of a new demographic theory of long-term social change with predictive power. This rather complex project structure is necessary for reaching generalizable and useful results. All components have been designed to complement each other to maximize the chances of achieving path-breaking and at the same time tangible results in this highly complex, multidisciplinary field. All components of the study will build on previous work of IIASA and Wolfgang Lutz and hence minimize the need to acquire additional experience for the case study sites or for the methodology used.

Project Generalized Homological Mirror Symmetry and Applications

Host Institution (HI) UNIVERSITAT WIEN
Call Details Advanced Grant (AdG), PE1, ERC-2008-AdG
Summary Mirror symmetry arose originally in physics, as a duality between $N = 2$ superconformal field theories. Witten formulated a more mathematically accessible version, in terms of topological field theories. Both conformal and topological field theories can be defined axiomatically, but more interestingly, there are several geometric ways of constructing them. A priori, the mirror correspondence is not unique, and it does not necessarily remain within a single class of geometric models. The classical case relates $\sigma$-models, but in a more modern formulation, one has mirror dualities between different Landau-Ginzburg models, as well as between such models and $\sigma$-models; orbifolds should also be included in this. The simplest example would be the function $W: \C \rightarrow \C$, $W(x) = x^{n+1}$, which is self-mirror (up to dividing by the $\bZ/n+1$ symmetry group, in an orbifold sense). While the mathematics of the $\sigma$-model mirror correspondence is familiar by now, generalizations to Landau-Ginzburg theories are only beginning to be understood. Today it is clear that Homologcal Mirror Symmetry (HMS) as a categorical correspondence works and it is time for developing direct geometric applications to classical problems - rationality of algebraic varieties and Hodge conjecture. This the main goal of the proposal. But in order to attack the above problems we need to generalize HMS and explore its connection to new developments in modern Hodge theory. In order to carry the above program we plan to further already working team Vienna, Paris, Moscow, MIT.

Project The Transformation of Global Health Governance: Competing Worldviews and Crises
Researcher (PI) Colin John Mcinnes
Host Institution (HI) ABERYSTWYTH UNIVERSITY
Call Details Advanced Grant (AdG), SH2, ERC-2008-AdG
Summary Globalisation has changed health conditions worldwide, affecting the lives and livelihoods of hundreds of millions. While historically many health issues have readily crossed borders (e.g. Black Plague), the intensification and extensification of contemporary globalisation processes has required new forms of governance to address changed global health needs. How do we collectively protect and promote health in an increasingly globalised world? This challenge has opened up a contested space known as global health governance (GHG) where the stakes are high but where different perspectives compete and contradict. It is also a poorly understood space. This programme aims to significantly advance our understanding of this space and the competition within it. It builds on a small body of existing literature to which the two applicants have already made important contributions, but represents a step change in two important respects. First, existing analyses have been limited to single approaches or perspectives. This programme represents the first sustained attempt at a comparative analysis incorporating a variety of perspectives and health issues. Given that the space is contested, it is only through such an analysis that we can significantly advance our understanding of GHG. Such an approach would represent a major advance on the current state of the art. Second, analysis to date has focused on disease and especially infectious disease. The applicants have been at the forefront of critiquing this approach as overly narrow (for example McInnes and Lee, 2006). This programme addresses infectious disease as one of the key issues in global health governance, but also incorporates non-communicable disease and non-disease based health issues in an explicit attempt to broaden the analysis to cover more fully the space occupied by global health governance.

Summary One of the major paradoxes in the geosciences is the contrast between the geochemical evidence for limited mass-exchange between lower and upper mantle, and the geophysical arguments for significant mass exchange, needed to prevent the mantle from melting in the geological past. Seismic tomography, when ultimately combined with geodynamical modeling, needs to provide estimates of present-day flux. Indeed, tomography has shown evidence for slabs penetrating into the lower mantle; but no quantitative information on the degree of mass exchange and heat flux can, as yet, reliably be obtained from tomographic images. It is crucial that the boundary between upper- and lower mantle be imaged at greater precision, certainly in the plume-rich southern hemisphere. This requires a combined effort of improvements both experimentally and theoretically. Much progress has recently been obtained by my group in Princeton before I returned to Europe. I propose to build upon those accomplishments, and to (1) Expand the data acquisition to the oceans by developing hydrophone-equipped floats, with the goal to improve data coverage in regions that are important to investigate heat flux: the plume-rich southern hemisphere in particular, (2) Combine different seismological data sets spanning a wide range of frequencies, with the goal to obtain tomographic images that allow for a quantitative estimate of heat flux (both upwards through plumes and downwards through the sinking of slab fragments), with emphasis on the boundary between upper- and lower mantle, (3) Exploit the extra resolution offered by the frequency-dependent sensitivity of body waves (multifrequency tomography), (4) Incorporate wavelet expansions into the tomographic inversion, with the aim to resolve more detail in the model where the data allow a higher resolution, (5) Obtain a multidisciplinary interpretation of new tomographic results through interaction with geodynamicists and geochemists.

Project Genetics of Mental Illness
Researcher (PI) Dorret Boomsma
Host Institution (HI) STICHTING VU
Call Details Advanced Grant (AdG), SH4, ERC-2008-AdG
Summary Mental disorders put a great burden on society and their impact on personal life can be devastating. Most mental disorders begin in childhood or adolescence and co-occur with somatic disease. In children, the most common problems are ADHD and anxious/depression and these problems often co-occur with additional behavioral and emotional problems. In adults, depression is the major mental disorder. It frequently co-occurs with anxiety disorders, substance abuse, migraine, cardiovascular disease and its associated risk factors. Indeed, depression is the largest cause of nonfatal disease burden in Western countries and increasingly in low and middle income countries worldwide as well. This application focuses on the genetics of common mental disorders, co-morbid traits and diseases across the lifespan. Its primary aim is the discovery of developmental paths into risk of depression and co-morbid disorders, using genetic epidemiological, molecular genetic and gene-environment interaction models. The introduction of multivariate and longitudinal models, in particular methods introduced by my group, into these areas will lead to substantial increases in power to unravel the contributions of genotype, environment and their interactions. The project described in this application addresses three interrelated topics: 1. Neuropsychiatric disorders and cognition 2. Depression, anxiety, substance use, abuse and dependence 3. Depression, migraine and cardiovascular risk As a connecting methodological framework it will develop models for the genetic analysis of these complex traits, especially gene-environment interaction and genome-wide association models. My ambition is to discover which genes influence the risk for mental disorder and co-morbid biomedical traits, to identify the causal variants, and to explore their interaction with environmental risk factors.

Project Gamma Ray Bursts as a Focal Point of High Energy Astrophysics
Researcher (PI) Tsvi Piran
Host Institution (HI) THE HEBREW UNIVERSITY OF JERUSALEM
Call Details Advanced Grant (AdG), PE9, ERC-2008-AdG
Summary Gamma-Ray Bursts (GRBs), short and intense bursts of gamma-rays originating from random directions in the sky, are the brightest explosions in our Universe. They involve ultra-relativistic motion, huge magnetic fields, the strongest gravitational fields, acceleration of photons, neutrinos and cosmic rays to ultra high energies, the collapse of massive stars, mergers of neutron star binaries and formation of newborn black holes. They are at the focal point of relativistic high energy astrophysics and they serve as the best laboratory for extreme physics. The internal-external shocks model was formulated to explain their inner working. This model had impressive successes in interpreting and predicting GRB properties. Still it had left many fundamental questions unanswered. Furthermore, recently it has been confronted with puzzling Swift observations of the early afterglow and it is not clear if it needs minor revisions or a drastic overhaul. I describe here an extensive research program that deals with practically all aspects of GRB. From a technical point of view this program involves sophisticated state of the art computations on one hand, fundamental theory and phenomenological analysis of observations and data analysis on the other one. My goal is to address both old and new open question, considering, among other options the possibility that the current model has to be drastically revised. My long term goal, beyond understanding the inner working of GRBs, is to create a unified theory of accretion acceleration and collimation and of emission of high energy gamma-rays and relativistic particles that will synergize our understanding of GRBs, AGNs, Microquasars, galactic binary black holes SNRs and other high energy astrophysics phenomena. A second hope is to find ways to utilize GRBs to reveal new physics that cannot be explored otherwise.

Host Institution (HI) KAROLINSKA INSTITUTET
Call Details Advanced Grant (AdG), LS2, ERC-2008-AdG
Summary The main scientific questions addressed in this proposal relate to the understanding of molecular mechanisms of growth control and cancer through the combined use of high-throughput technologies and computational biology. We aim to create a systems-level understanding of the cell cycle, and its regulation by physiological growth factors and oncogenes through the use high-throughput biology to identify all or the majority of genes that are essential for cell cycle progression, and by combining this dataset with computationally predicted and experimentally validated target genes of growth factors and oncogenic pathways. In my opinion, such systems biology approach is critical for understanding of growth control, as organ-specific growth control has proven particularly refractory to genetic dissection. Much of what we know about physiological mechanisms controlling cellular growth in mammals has been revealed by human cancer genetics. These studies have revealed that a large number of genes can contribute to aberrant cell growth; there are more than 300 genes that have been linked to cancer, and mutations found in cancer are often cell type specific ( oncogene preference , i.e. PTCH mutations in medulloblastoma, APC in colon cancer, TMPRSS2-ERG in prostate cancer), suggesting that different pathways in different cell lineages are coupled to the cell cycle machinery. We have preliminary evidence that hedgehog (Hh) and Wnt signals are directly coupled to expression of N-myc and c-Myc genes, but only in tissues and cell-types that display a proliferative response to these factors. Both classical molecular and developmental biology as well as high throughput and systems biological methods will be used for dissection of the molecular mechanism of this selectivity. If successful, these experiments would establish a principle explaining why particular mutations are extremely common in some tumor types but not found at all in others.

Project Game Theory and Applications in the Presence of Cognitive Limitations
Researcher (PI) Philippe Jehiel
Host Institution (HI) ECOLE D'ECONOMIE DE PARIS
Call Details Advanced Grant (AdG), SH1, ERC-2008-AdG
Summary Game theory has been very successful in shaping modern economic theory over the past fifty years. Yet, the solution concepts developed under the assumption of perfect rationality require a degree of cognitive sophistication on players part that need not be realistic. In this project, I wish to broaden the definitions of equilibrium concepts to take into account the cognitive limitations of players. Armed with these equilibrium concepts, I wish to revisit a number of classic economic applications of game theory and economics in the hope that the proposed approach enhances our economic understanding. I also wish to check whether the proposed concepts are confirmed experimentally. Specifically, the project will rely on three new solution concepts I have recently introduced: the limited foresight equilibrium (Jehiel, 1995) in which players are viewed as knowing only the evolution of moves over the next n periods, the analogy-based expectation equilibrium (Jehiel, 2005) in which players understand only the average behavioural strategy of their opponents over bundles of states, and the valuation equilibrium (Jehiel and Samet, 2007) in which players attach the same valuation to a bundle of moves (possibly corresponding to different decision nodes). In each case, I assume that players choose their strategy based on the simplest representation of their environment that is consistent with their partial understanding. And as in the standard rationality paradigm, I assume that the partial understanding of players as parameterized by their cognitive type is correct. The heart of the project is to show how these approaches can be used to shed new light on major subfields of economic theory such as mechanism design, the theory of reputation, the theory of incomplete contracts and the theory of speculative markets. I also wish to test experimentally the solution concepts so as to check their empirical validity.

Project Gut immunity and homeostasis in Drosophila
Researcher (PI) Bruno Lemaitre
Host Institution (HI) ECOLE POLYTECHNIQUE FEDERALE DE LAUSANNE
Call Details Advanced Grant (AdG), LS6, ERC-2008-AdG
Summary The gut is the major interface between microbes and their animal hosts and constitutes the main entry route for pathogens. As a consequence gut cells must be armed with efficient immune defenses to combat invasion and colonisation by pathogens. However, the gut also harbors a flora of commensal bacteria, with potentially beneficial effects for the host, which must be tolerated without a chronic, and harmful, immune response. In recent years Drosophila has emerged as a powerful model to dissect host-pathogen interactions, leading to the paradigm of antimicrobial peptide regulation by the Toll and Imd signaling pathways. The strength of this model derives from the availability of powerful and cost effective genetic and genomic tools as well as the high degree of similarities to vertebrate innate immunity. However, in spite of growing interest in gut mucosal immunity generally, very little is known about the immune response of the Drosophila gut. Using powerful new tools and those developed in the study of the systemic response, we propose to raise our understanding of Drosophila gut immunity to the same level as that of systemic immunity within the next five years. This project will involve integrated approaches to dissect not only the gut immune response but also gut homeostasis in the presence of commensal microbiota, as well as strategies used by entomopathogens to circumvent these defenses. We believe that the fundamental knowledge generated on Drosophila gut immunity will serve as a paradigm of epithelial immune reactivity and have a wider impact on our comprehension of animal defense mechanisms.
