Summary Computational Electromagnetics (CEM) is the scientific field at the origin of all new modeling and simulation tools required by the constantly arising design challenges of emerging and future technologies in applied electromagnetics. As in many other technological fields, however, the trend in all emerging technologies in electromagnetic engineering is going towards miniaturized, higher density and multi-scale scenarios. Computationally speaking this translates in the steep increase of the number of degrees of freedom. Given that the design cost (the cost of a multi-right-hand side problem dominated by matrix inversion) can scale as badly as cubically with these degrees of freedom, this fact, as pointed out by many, will sensibly compromise the practical impact of CEM on future and emerging technologies.
For this reason, the CEM scientific community has been looking for years for a FFT-like paradigm shift: a dynamic fast direct solver providing a design cost that would scale only linearly with the degrees of freedom. Such a fast solver is considered today a Holy Grail of the discipline.
The Grand Challenge of 321 will be to tackle this Holy Grail in Computational Electromagnetics by investigating a dynamic Fast Direct Solver for Maxwell Problems that would run in a linear-instead-of-cubic complexity for an arbitrary number and configuration of degrees of freedom.
The failure of all previous attempts will be overcome by a game-changing transformation of the CEM classical problem that will leverage on a recent breakthrough of the PI. Starting from this, the project will investigate an entire new paradigm for impacting algorithms to achieve this grand challenge.
The impact of the FFT’s quadratic-to-linear paradigm shift shows how computational complexity reductions can be groundbreaking on applications. The cubic-to-linear paradigm shift, which the 321 project will aim for, will have such a rupturing impact on electromagnetic science and technology.

Project Shaping a European Scientific Scene : Alfonsine Astronomy
Researcher (PI) Matthieu Husson
Host Institution (HI) CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE CNRS
Country France
Call Details Consolidator Grant (CoG), SH6, ERC-2016-COG
Summary Alfonsine astronomy is arguably among the first European scientific achievements. It shaped a scene for actors like Regiomontanus or Copernicus. There is however little detailed historical analysis encompassing its development in its full breadth. ALFA addresses this issue by studying tables, instruments, mathematical and theoretical texts in a methodologically innovative way relying on approaches from the history of manuscript cultures, history of mathematics, and history of astronomy.
ALFA integrates these approaches not only to benefit from different perspectives but also to build new questions from their interactions. For instance the analysis of mathematical practices in astral sciences manuscripts induces new ways to analyse the documents and to think about astronomical questions.
Relying on these approaches the main objectives of ALFA are thus to:
- Retrace the development of the corpus of Alfonsine texts from its origin in the second half of the 13th century to the end of the 15th century by following, on the manuscript level, the milieus fostering it;
- Analyse the Alfonsine astronomers’ practices, their relations to mathematics, to the natural world, to proofs and justification, their intellectual context and audiences;
- Build a meaningful narrative showing how astronomers in different milieus with diverse practices shaped, also from Arabic materials, an original scientific scene in Europe.
ALFA will shed new light on the intellectual history of the late medieval period as a whole and produce a better understanding of its relations to related scientific periods in Europe and beyond. It will also produce methodological breakthroughs impacting the ways history of knowledge is practiced outside the field of ancient and medieval sciences. Efforts will be devoted to bring these results not only to the relevant scholarly communities but also to a wider audience as a resource in the public debates around science, knowledge and culture.

Call Details Consolidator Grant (CoG), PE2, ERC-2016-COG
Summary This project focuses on developing quantum field theory methods and applying them to the phenomenology of elementary particles. At the Large Hadron Collider (LHC) our current best theoretical understanding of particle physics is being tested against experiment by measuring e.g. properties of the recently discovered Higgs boson. With run two of the LHC, currently underway, the experimental accuracy will further increase. Theoretical predictions matching the latter are urgently needed. Obtaining these requires extremely difficult calculations of scattering amplitudes and cross sections in quantum field theory, including calculations to correctly describe large contributions due to long-distance physics in the latter. Major obstacles in such computations are the large number of Feynman diagrams that are difficult to handle, even with the help of modern computers, and the computation of Feynman loop integrals. To address these issues, we will develop innovative methods that are inspired by new structures found in supersymmetric field theories. We will extend the scope of the differential equations method for computing Feynman integrals, and apply it to scattering processes that are needed for phenomenology, but too complicated to analyze using current methods. Our results will help measure fundamental parameters of Nature, such as, for example, couplings of the Higgs boson, with unprecedented precision. Moreover, by accurately predicting backgrounds from known physics, our results will also be invaluable for searches of new particles.

Call Details Consolidator Grant (CoG), SH2, ERC-2016-COG
Summary Knowledge is an anthropological constant that is indissociable from the birth and interactions of human societies, but is at best a secondary concern for scholars of international relations and globalization. Contemporary global studies are thus unable to account for the co-constitution of knowledge and politics at a macro-scale, and remain especially blind to the historical patterns of epistemic development that operate at the level of the species as a whole and have shaped its global political history in specific, path-dependent ways up to now.
ARTEFACT is the first project to pursue a knowledge-centered investigation of global politics. It is uniquely grounded in an anthropological approach that treats globalization and human knowledges beyond their modern manifestations, from the longue-durée perspective of our species’ social history. 'The global as artefact' is more than a metaphor. It reflects the premise that human collectives 'make' the political world not merely through ideas, language, or norms, but primordially through the material infrastructures, solutions, objects, practices, and skills they develop in response to evolving structural challenges.
ARTEFACT takes agriculture as an exemplary and especially timely case-study to illuminate the entangled global histories of knowledge and politics, analyzing and comparing four increasingly inclusive 'global political systems' of the Ancient, Medieval, Modern, and Contemporary eras and their associated agrarian socio-epistemic revolutions.
ARTEFACT ultimately aims to 1) develop an original theory of the global, 2) launch Global Knowledge Studies as a new cross-disciplinary domain of systematic empirical and theoretical study, and 3) push the respective boundaries of the anthropology of knowledge, global history, and international theory beyond the state-of-the-art and toward a holistic understanding that can illuminate how past trends of socio-epistemic evolution might shape future paths of global life.

Country Netherlands
Call Details Consolidator Grant (CoG), LS7, ERC-2016-COG
Summary In many prevalent autoimmune diseases such as rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) autoantibodies are used as diagnostic and prognostic tools. Several of these autoantibodies target proteins that have been post-translationally modified (PTM). Examples of such modifications are citrullination and carbamylation. The success of B cell-targeted therapies in many auto-antibody positive diseases suggests that B cell mediated auto-immunity is playing a direct pathogenic role. Despite the wealth of information on the clinical associations of these anti-PTM protein antibodies as biomarkers we have currently no insight into why these antibodies are formed.
Immunization studies reveal that PTM proteins can induce antibody responses even in the absence of exogenous adjuvant. The reason why these PTM proteins have ‘autoadjuvant’ properties that lead to a breach of tolerance is currently unknown. In this proposal, I hypothesise that the breach of tolerance towards PTM proteins is mediated by complement factors that bind directly to these PTM. Our preliminary data indeed reveal that several complement factors bind specifically to PTM proteins. Complement could be involved in the autoadjuvant property of PTM proteins as next to killing pathogens complement can also boost adaptive immune responses. I plan to unravel the importance of the complement–PTM protein interaction by answering these questions:
1) What is the physiological function of complement binding to PTM proteins?
2) Is the breach of tolerance towards PTM proteins influenced by complement?
3) Can the adjuvant function of PTM be used to increase vaccine efficacy and/or decrease autoreactivity?
With AUTOCOMPLEMENT I will elucidate how PTM-reactive B cells receive ‘autoadjuvant’ signals. This insight will impact on patient care as we can now design strategies to either block unwanted ‘autoadjuvant’ signals to inhibit autoimmunity or to utilize ‘autoadjuvant’ signals to potentiate vaccination.

Summary This project focuses on the historical analysis of institutions and their impact on economic development through the investigation of a legal instrument – general average (GA) – which underpins maritime trade by redistributing damages’ costs across all interested parties. This will be pursued through the comparative investigation of GA in those European countries where substantial data exists: Italy, Spain, England, France and the Low Countries (1500-1800). Average and insurance were both created in the Middle Ages to facilitate trade through the redistribution of risk. Insurance has been widely studied, average – the expenses which can befall ships and cargoes from the time of their loading aboard until their unloading (due to accidents, jettison, and unexpected costs) – has been neglected. GA still plays an essential role in the redistribution of transaction costs, and being a form of strictly mutual self-protection, never evolved into a speculative financial instrument as insurance did; it therefore represents an excellent case of long-term effectiveness of a non-market economic phenomenon. Although the principle behind GA was very similar across Europe, in practice there were substantial differences in declaring and adjudicating claims. GA reports provide unparalleled evidence on maritime trade which, analysed quantitatively and quantitatively through a novel interdisciplinary approach, will contribute to the reassessment of the role played by the maritime sector in fostering economic growth during the early modern first globalization, when GA was the object of fierce debates on state jurisdiction and standardization of practice. Today they are regulated by the York-Antwerp Rules (YAR), currently under revision. This timely conjuncture provides plenty of opportunities for active engagement with practitioners, thereby fostering a creative dialogue on GA historical study and its future development to better face the challenges of mature globalization.

Call Details Consolidator Grant (CoG), SH6, ERC-2016-COG
Summary The Bantu Expansion is not only the main linguistic, cultural and demographic process in Late Holocene Africa. It is also one of the most controversial issues in African History that still has political repercussions today. It has sparked debate across the disciplines and far beyond Africanist circles in an attempt to understand how the young Bantu language family (ca. 5000 years) could spread over large parts of Central, Eastern and Southern Africa. This massive dispersal is commonly seen as the result of a single migratory macro-event driven by agriculture, but many questions about the movement and subsistence of ancestral Bantu speakers are still open. They can only be answered through real interdisciplinary collaboration. This project will unite researchers with outstanding expertise in African archaeology, archaeobotany and historical linguistics to form a unique cross-disciplinary team that will shed new light on the first Bantu-speaking village communities south of the rainforest. Fieldwork is planned in parts of the Democratic Republic of Congo, the Republic of Congo and Angola that are terra incognita for archaeologists to determine the timing, location and archaeological signature of the earliest villagers and to establish how they interacted with autochthonous hunter-gatherers. Special attention will be paid to archaeobotanical and palaeoenvironmental data to get an idea of their subsistence, diet and habitat. Historical linguistics will be pushed beyond the boundaries of vocabulary-based phylogenetics and open new pathways in lexical reconstruction, especially regarding subsistence and land use of early Bantu speakers. Through interuniversity collaboration archaeozoological, palaeoenvironmental and genetic data and phylogenetic modelling will be brought into the cross-disciplinary approach to acquire a new holistic view on the interconnections between human migration, language spread, climate change and early farming in Late Holocene Central Africa.

Host Institution (HI) UNIVERSITA DEGLI STUDI DI TORINO
Country Italy
Call Details Consolidator Grant (CoG), LS7, ERC-2016-COG
Summary Monoclonal antibodies against the EGF receptor (EGFR) provide substantive benefit to colorectal cancer (CRC) patients. However, no genetic lesions that robustly predict ‘addiction’ to the EGFR pathway have been yet identified. Further, even in tumours that regress after EGFR blockade, subsets of drug-tolerant cells often linger and foster ‘minimal residual disease’ (MRD), which portends tumour relapse.
Our preliminary evidence suggests that reliance on EGFR activity, as opposed to MRD persistence, could be assisted by genetically-based variations in transcription factor partnerships and activities, gene expression outputs, and biological fates controlled by the WNT/beta-catenin pathway. On such premises, BEAT (Beta-catenin and EGFR Abrogation Therapy) will elucidate the mechanisms of EGFR dependency, and escape from it, with the goal to identify biomarkers for more efficient clinical management of CRC and develop new therapies for MRD eradication.
A multidisciplinary approach will be pursued spanning from integrative gene regulation analyses to functional genomics in vitro, pharmacological experiments in vivo, and clinical investigation, to address whether: (i) specific genetic alterations of the WNT pathway affect anti-EGFR sensitivity; (ii) combined neutralisation of EGFR and WNT signals fuels MRD deterioration; (iii) data from analysis of this synergy can lead to the discovery of clinically meaningful biomarkers with predictive and prognostic significance.
This proposal capitalises on a unique proprietary platform for high-content studies based on a large biobank of viable CRC samples, which ensures strong analytical power and unprecedented biological flexibility. By providing fresh insight into the mechanisms whereby WNT/beta-catenin signalling differentially sustains EGFR dependency or drug tolerance, the project is expected to put forward an innovative reinterpretation of CRC molecular bases and advance the rational application of more effective therapies.

Project New discrete choice theory for understanding moral decision making behaviour
Researcher (PI) Caspar Gerard CHORUS
Host Institution (HI) TECHNISCHE UNIVERSITEIT DELFT
Country Netherlands
Call Details Consolidator Grant (CoG), SH2, ERC-2016-COG
Summary Discrete choice theory provides a mathematically rigorous framework to analyse and predict choice behaviour. While many of the theory’s key developments originate from the domain of transportation (mobility, travel behaviour), it is now widely used throughout the social sciences.
The theory has a blind spot for moral choice behaviour. It was designed to analyse situations where people make choices that are optimal given their consumer preferences, rather than situations where people attempt to make choices that are right, given their moral preferences. This neglect of the morality of choice is striking, in light of the fact that many of the most important choices people make, have a moral dimension.
This research program extends discrete choice theory to the domain of moral decision making.
It will produce a suite of new mathematical representations of choice behaviour (i.e., choice models), which are designed to capture the decision rules and decision weights that determine how individuals behave in moral choice situations. In these models, particular emphasis is given to heterogeneity in moral decision rules and to the role of social influences. Models will be estimated and validated using data obtained through a series of interviews, surveys and choice experiments. Empirical analyses will take place in the context of moral choice situations concerning i) co-operative road using and ii) unsafe driving practices. Estimation results will be used as input for agent based models, to identify how social interaction processes lead to the emergence, persistence or dissolution of moral (traffic) equilibria at larger spatio-temporal scales.
Together, these proposed research efforts promise to generate a major breakthrough in discrete choice theory. In addition, the program will result in important methodological contributions to the empirical study of moral decision making behaviour in general; and to new insights into the moral aspects of (travel) behaviour.

Call Details Consolidator Grant (CoG), LS1, ERC-2016-COG
Summary The Endoplasmic Reticulum (ER) membrane in all eukaryotic cells has an intricate protein network that facilitates protein biogene-sis and homeostasis. The molecular complexity and sophisticated regulation of this machinery favours study-ing it in its native microenvironment by novel approaches. Cryo-electron tomography (CET) allows 3D im-aging of membrane-associated complexes in their native surrounding. Computational analysis of many sub-tomograms depicting the same type of macromolecule, a technology I pioneered, provides subnanometer resolution insights into different conformations of native complexes.
I propose to leverage CET of cellular and cell-free systems to reveal the molecular details of ER protein bio-genesis and homeostasis. In detail, I will study: (a) The structure of the ER translocon, the dynamic gateway for import of nascent proteins into the ER and their maturation. The largest component is the oligosaccharyl transferase complex.

Summary
The Endoplasmic Reticulum (ER) membrane in all eukaryotic cells has an intricate protein network that facilitates protein biogene-sis and homeostasis. The molecular complexity and sophisticated regulation of this machinery favours study-ing it in its native microenvironment by novel approaches. Cryo-electron tomography (CET) allows 3D im-aging of membrane-associated complexes in their native surrounding. Computational analysis of many sub-tomograms depicting the same type of macromolecule, a technology I pioneered, provides subnanometer resolution insights into different conformations of native complexes.
I propose to leverage CET of cellular and cell-free systems to reveal the molecular details of ER protein bio-genesis and homeostasis. In detail, I will study: (a) The structure of the ER translocon, the dynamic gateway for import of nascent proteins into the ER and their maturation. The largest component is the oligosaccharyl transferase complex. (b) Cotranslational ER import, N-glycosylation, chaperone-mediated stabilization and folding as well as oligomerization of established model substrate such a major histocompatibility complex (MHC) class I and II complexes. (c) The degradation of misfolded ER-residing proteins by the cytosolic 26S proteasome using cytomegalovirus-induced depletion of MHC class I as a model system. (d) The structural changes of the ER-bound translation machinery upon ER stress through IRE1-mediated degradation of mRNA that is specific for ER-targeted proteins. (e) The improved ‘in silico purification’ of different states of native macromolecules by maximum likelihood subtomogram classification and its application to a-d.
