Summary The traditional (Riemann) approach to analytic number theory uses the zeros of zeta functions. This requires the associated multiplicative function, say f(n), to have special enough properties that the associated Dirichlet series may be analytically continued. In this proposal we continue to develop an approach which requires less of the multiplicative function, linking the original question with the mean value of f. Such techniques have been around for a long time but have generally been regarded as “ad hoc”. In this project we aim to show that one can develop a coherent approach to the whole subject, not only reproving all of the old results, but also many new ones that appear inaccessible to traditional methods.
Our first goal is to complete a monograph yielding a reworking of all the classical theory using these new methods and then to push forward in new directions. The most important is to extend these techniques to GL(n) L-functions, which we hope will now be feasible having found the correct framework in which to proceed. Since we rarely know how to analytically continue such L-functions this could be of great benefit to the subject.
We are developing the large sieve so that it can be used for individual moduli, and will determine a strong form of that. Also a new method to give asymptotics for mean values, when they are not too small.
We wish to incorporate techniques of analytic number theory into our theory, for example recent advances on mean values of Dirichlet polynomials. Also the recent breakthroughs on the sieve suggest strong links that need further exploration.
Additive combinatorics yields important results in many areas. There are strong analogies between its results, and those for multiplicative functions, especially in large value spectrum theory, and its applications. We hope to develop these further.
Much of this is joint work with K Soundararajan of Stanford University.

Project acronym 3DIMAGE
Project 3D Imaging Across Lengthscales: From Atoms to Grains
Researcher (PI) Paul Anthony Midgley

Call Details Advanced Grant (AdG), PE4, ERC-2011-ADG_20110209
Summary "Understanding structure-property relationships across lengthscales is key to the design of functional and structural materials and devices. Moreover, the complexity of modern devices extends to three dimensions and as such 3D characterization is required across those lengthscales to provide a complete understanding and enable improvement in the material’s physical and chemical behaviour. 3D imaging and analysis from the atomic scale through to granular microstructure is proposed through the development of electron tomography using (S)TEM, and ‘dual beam’ SEM-FIB, techniques offering complementary approaches to 3D imaging across lengthscales stretching over 5 orders of magnitude.
We propose to extend tomography to include novel methods to determine atom positions in 3D with approaches incorporating new reconstruction algorithms, image processing and complementary nano-diffraction techniques. At the nanoscale, true 3D nano-metrology of morphology and composition is a key objective of the project, minimizing reconstruction and visualization artefacts. Mapping strain and optical properties in 3D are ambitious and exciting challenges that will yield new information at the nanoscale. Using the SEM-FIB, 3D ‘mesoscale’ structures will be revealed: morphology, crystallography and composition can be mapped simultaneously, with ~5nm resolution and over volumes too large to tackle by (S)TEM and too small for most x-ray techniques. In parallel, we will apply 3D imaging to a wide variety of key materials including heterogeneous catalysts, aerospace alloys, biomaterials, photovoltaic materials, and novel semiconductors.
We will collaborate with many departments in Cambridge and institutes worldwide. The personnel on the proposal will cover all aspects of the tomography proposed using high-end TEMs, including an aberration-corrected Titan, and a Helios dual beam. Importantly, a postdoc is dedicated to developing new algorithms for reconstruction, image and spectral processing."

Project African Governance and Space: Transport Corridors, Border Towns and Port Cities in Transition
Researcher (PI) Paul Christopher Nugent

Call Details Advanced Grant (AdG), SH2, ERC-2014-ADG
Summary AFRIGOS investigates the process of 'respacing' Africa, a political drive towards regional and continental integration, on the one hand, and the re-casting of Africa's engagement with the global economy, on the other. This is reflected in unprecedented levels of investment in physical and communications infrastructure, and the outsourcing of key functions of Customs, Immigration and security agencies. AFRIGOS poses the question of how far respacing is genuinely forging institutions that are facilitating or obstructing the movement of people and goods; that are enabling or preventing urban and border spaces from being more effectively and responsively governed; and that take into account the needs of African populations whose livelihoods are rooted in mobility and informality. The principal research questions are approached through a comparative study of port cities, border towns and other strategic nodes situated along the busiest transport corridors in East, Central, West and Southern Africa. These represent sites of remarkable dynamism and cosmopolitanism, which reflects their role in connecting African urban centres to each other and to other global cities.
AFRIGOS considers how governance 'assemblages' are forged at different scales and is explicitly comparative. It works through 5 connected Streams that address specific questions: 1. AGENDA-SETTING is concerned with policy (re-)formulation. 2. PERIPHERAL URBANISM examines governance in border towns and port cities. 3. BORDER WORKERS addresses everyday governance emerging through the interaction of officials and others who make their livelihoods from the border. 4. CONNECTIVE INFRASTRUCTURE looks as the transformative effects of new technologies. 5. PEOPLE & GOODS IN MOTION traces the passage of people and goods and the regimes of regulation to which they are subjected. AFRIGOS contributes to interdisciplinary research on borderland studies, multi-level governance and the everyday state.

Project Addressing global sustainability challenges by changing perceptions in catalyst design

Host Institution (HI) CARDIFF UNIVERSITY
Country United Kingdom
Call Details Advanced Grant (AdG), PE4, ERC-2011-ADG_20110209
Summary One of the greatest challenges facing society is the sustainability of resources. At present, a step change in the sustainable use of resources is needed and catalysis lies at the heart of the solution by providing new routes to carbon dioxide mitigation, energy security and water conservation. It is clear that new high efficiency game-changing catalysts are required to meet the challenge. This proposal will focus on excellence in catalyst design by learning from recent step change advances in gold catalysis by challenging perceptions. Intense interest in gold catalysts over the past two decades has accelerated our understanding of gold particle-size effects, gold-support and gold-metal interactions, the interchange between atomic and ionic gold species, and the role of the gold-support interface in creating and maintaining catalytic activity. The field has also driven the development of cutting-edge techniques, particularly in microscopy and transient kinetics, providing detailed structural characterisation on the nano-scale and probing the short-range and often short-lived interactions. By comparison, our understanding of other metal catalysts has remained relatively static.
The proposed programme will engender a step change in the design of supported-metal catalysts, by exploiting the learning and the techniques emerging from gold catalysis. The research will be set out in two themes. In Theme 1 two established key grand challenges will be attacked; namely, energy vectors and greenhouse gas control. Theme 2 will address two new and emerging grand challenges in catalysis namely the effective low temperature activation of primary carbon hydrogen bonds and CO2 utilisation where instead of treating CO2 as a thermodynamic endpoint, the aim will be to re-use it as a feedstock for bulk chemical and fuel production. The legacy of the research will be the development of a new catalyst design approach that will provide a tool box for future catalyst development.

Project Arctic Domestication: Emplacing Human-Animal Relationships in the Circumpolar North

Country United Kingdom
Call Details Advanced Grant (AdG), SH2, ERC-2011-ADG_20110406
Summary This 6-year project aims to co-ordinate field research in each of these fields to elaborate a new model of emplaced human-animal relations evoking recent theoretical concerns of the definition of the person, the attribution of agency, and renewed attention to ‘built environments’. The project will work inductively from empirical observations in seven field sites across the circumpolar Arctic from the Russian Federation, to Fennoscandia, to Canada. The circumpolar Arctic originally provided many of the primary thought experiments for classic models of cultural evolution. It has now again become the focus of powerful debates over the balance between the protection of cultural heritage and the development of natural resources to fuel a future for industrial economies. The human-non-human relationships chosen for study cover the full range of theoretical and political discourse within the sciences today from primary encounters in domination to contemporary bio-technical innovations in farming. The team will transcend typical ‘existential’ models of domination between people and animals by describing complex social settings where more than one species interact with the cultural landscape. The team will also challenge existing definitions between wild and tame by instead examining what links these behaviour types together. Further, the team members will examine how domestication was never a sudden, fleeting intuition but rather a process wherein people and domesticates are sometimes closer and sometimes farther from each other. Finally, the research team, working within the above mentioned literatures, will develop a renewed model – a new way of describing – these relationships which does not necessarily rely upon metaphors of domination, competition, individual struggle, origins, or hybridity. The strength of the team, and the principle investigator, is their demonstrated ability to carry out fieldwork in this often difficult to access region.

Summary With the prevalence of mobile computing devices and the increasing availability of pervasive services, ubiquitous computing (Ubicomp) is a reality for many people. This reality is generating opportunities for people to interact socially in new and richer ways, and to work more effectively in a variety of new environments. More generally, Ubicomp infrastructures – controlled by software – will determine users’ access to critical services.
With these opportunities come higher risks of misuse by malicious agents. Therefore, the role and design of software for managing use and protecting against misuse is critical, and the engineering of software that is both functionally effective while safe guarding user assets from harm is a key challenge. Indeed the very nature of Ubicomp means that software must adapt to the changing needs of users and their environment, and, more critically, to the different threats to users’ security and privacy.
ASAP proposes to radically re-conceptualise software engineering for Ubicomp in ways that are cognisant of the changing functional needs of users, of the changing threats to user assets, and of the changing relationships between them. We propose to deliver adaptive software capabilities for supporting users in managing their privacy requirements, and adaptive software capabilities to deliver secure software that underpin those requirements. A key novelty of our approach is its holistic treatment of security and human behaviour. To achieve this, it draws upon contributions from requirements engineering, security & privacy engineering, and human-computer interaction. Our aim is to contribute to software engineering that empowers and protects Ubicomp users. Underpinning our approach will be the development of representations of security and privacy problem structures that capture user requirements, the context in which those requirements arise, and the adaptive software that aims to meet those requirements.

Summary "This is a programme of advanced research with potential for high scientific impact and applications to areas of great strategic importance such as renewable energy and biomolecular technology. The aim is to develop and apply a combination of cutting-edge tools to observe and understand dynamics in molecules and condensed phase matter with attosecond temporal and nanometre spatial resolutions. The programme, will exploit two new types of measurements that my group have already begun to develop: high harmonic generation (HHG) spectroscopy and attosecond absorption pump-probe spectroscopy, and will apply them to the measurement of attosecond electron dynamics in large molecules and the condensed phase. These methods rely upon the emission and transmission of soft X-ray attosecond fields that make accessible measurement not only of larger molecules in the gas phase but also thin (micron to nanometre) samples in the condensed phase. This is a research project that will open new frontiers both experimentally and theoretically. The challenge of this research is high and will be met by a concerted programme that is well matched to my teams experimental and theoretical expertise in attosecond physics, ultrafast intense-field science, soft X-ray techniques and advanced techniques for creating gaseous and condensed phase samples."

Summary This project will investigate the interface between the study of the bible and the study of antiquity in the nineteenth century. These two areas -- the bible and classics -- are central to the intellectual world of the 19th century, a source of knowledge, contention, and authority both as discrete topics, and, more importantly, in relation to and in competition with one another. It is impossible to understand Victorian society without appreciating the intellectual, social and institutional force of these concerns with the past. Yet modern disciplinary formation has not only separated them in the academy, but also marginalized both subject areas -- which has deeply attenuated comprehension of this foundational era. Our project will bring together scholars working on a range of fields including classics, history of education, cultural history, art history, literary history to bring back into view a fundamental but deeply misunderstood and underexplored aspect of the nineteenth century, which continues to have a significant impact on the contemporary world.

Summary The promise of cognitive neuroscience is truly exciting – to link mind and brain in order to reveal the neural basis of higher cognitive functions. This is crucial, scientifically, if we are to understand the nature of mental processes and how they arise from neural machinery but also, clinically, if we are to establish the basis of neurological patients’ impairments, their clinical management and treatment. Cognitive-clinical neuroscience depends on three ingredients: (a) investigating complex mental behaviours and the underlying cognitive processes; (b) mapping neural systems and their function; and (c) methods and tools that can bridge the gap between brain and mental behaviour. Experimental psychology and behavioural neurology has delivered the first component. In vivo neuroimaging and other allied technologies allow us to probe and map neural systems, their connectivity and neurobiological responses. The principal aim of this ERC Advanced grant is to secure, for the first time, the crucial third ingredient – the methods and tools for bridging systematically between cognitive science and systems neuroscience.
The grant will be based on two main activities: (i) convergence of methods – instead of employing each neuroscience and cognitive method independently, they will be planned and executed simultaneously to force a convergence of results; and (ii) development of a new type of neurocomputational model - to provide a novel formalism for bridging between brain and cognition. Computational models are used in cognitive science to mimic normal and impaired behaviour. Such models also have an as-yet untapped potential to connect neuroanatomy and cognition: latent in every model is a kind of brain-mind duality – each model is based on a computational architecture which generates behaviour. We will retain the ability to simulate detailed cognitive behaviour but simultaneously make the models’ architecture reflect systems-level neuroanatomy and function.

Summary Ultrafast laser methods will be employed to examine the dynamics of chemical and photochemical reactions in liquid solutions. By contrasting the solution phase dynamics with those observed for isolated collisions in the gas phase, the fundamental role of solvent on chemical pathways will be explored at a molecular level. The experimental studies will be complemented by computational simulations that explicitly include treatment of the effects of solvent on reaction energy pathways and reactant and product motions.
The research addresses a major challenge in Chemistry to understand the role of solvent on the mechanisms of chemical reactions. Questions that will be examined include how the solvent modifies reaction barriers and other regions of the reaction potential energy surface (PESs), alters the couplings between PESs, most importantly at conical intersections between electronic states, influences and constrains the dynamical stereochemistry of passage through transition states, and dissipates excess product energy.
The experimental strategy will be to obtain absorption spectra of transient species with lifetimes of ~100 fs – 1000 ps using broad bandwidth light sources in the infrared, visible and ultraviolet regions. Time-evolutions of such spectra reveal the formation and decay of short-lived species that might be highly reactive radicals or internally (vibrationally and electronically) excited molecules. The transient species decay by reaction or energy loss to the solvent. Statistical mechanical theories of reactions in solution treat such processes using linear response theory, but the experimental data will challenge this paradigm by seeking evidence for breakdown of the linear response interaction of solvent and solute on short timescales because of microscopic chemical dynamics that perturb the solvent structure. The work will build on our pioneering experiments at the Rutherford Appleton Laboratory that prove the feasilbility of the methods.
