Summary The 0MSPIN project consists of an extensive integrated theoretical, experimental and device development programme of research opening a radical new approach to spintronics. Spintronics has the potential to supersede existing storage and memory applications, and to provide alternatives to current CMOS technology. Ferromagnetic matels used in all current spintronics applications may make it impractical to realise the full potential of spintronics. Metals are unsuitable for transistor and information processing applications, for opto-electronics, or for high-density integration. The 0MSPIN project aims to remove the major road-block holding back the development of spintronics in a radical way: removing the ferromagnetic component from key active parts or from the whole of the spintronic devices. This approach is based on exploiting the combination of exchange and spin-orbit coupling phenomena and material systems with zero macroscopic moment. The goal of the 0MSPIN is to provide a new paradigm by which spintronics can enter the realms of conventional semiconductors in both fundamental condensed matter research and in information technologies. In the central part of the proposal, the research towards this goal is embedded within a materials science project whose aim is to introduce into physics and microelectronics an entirely new class of semiconductors. 0MSPIN seeks to exploit three classes of material systems: (1) Antiferromagnetic bi-metallic 3d-5d alloys (e.g. Mn2Au). (2) Antiferromagnetic I-II-V semiconductors (e.g. LiMnAs). (3) Non-magnetic spin-orbit coupled semiconductors with injected spin-polarized currents (e.g. 2D III-V structures). Proof of concept devices operating at high temperatures will be fabricated to show-case new functionalities offered by zero-moment systems for sensing and memory applications, information processing, and opto-electronics technologies.

Summary The suite of graphene’s unique properties and applications can be enormously enhanced by its functionalization. As non-covalently functionalized graphenes do not target all graphene’s properties and may suffer from limited stability, covalent functionalization represents a promising way for controlling graphene’s properties. To date, only a few well-defined graphene derivatives have been introduced. Among them, fluorographene (FG) stands out as a prominent member because of its easy synthesis and high stability. Being a perfluorinated hydrocarbon, FG was believed to be as unreactive as the two-dimensional counterpart perfluoropolyethylene (Teflon®). However, our recent experiments showed that FG is not chemically inert and can be used as a viable precursor for synthesizing graphene derivatives. This surprising behavior indicates that common textbook grade knowledge cannot blindly be applied to the chemistry of 2D materials. Further, there might be specific rules behind the chemistry of 2D materials, forming a new chemical discipline we tentatively call 2D chemistry. The main aim of the project is to explore, identify and apply the rules of 2D chemistry starting from FG. Using the knowledge gained of 2D chemistry, we will attempt to control the chemistry of various 2D materials aimed at preparing stable graphene derivatives with designed properties, e.g., 1-3 eV band gap, fluorescent properties, sustainable magnetic ordering and dispersability in polar media. The new graphene derivatives will be applied in sensing, imaging, magnetic delivery and catalysis and new emerging applications arising from the synergistic phenomena are expected. We envisage that new applications will be opened up that benefit from the 2D scaffold and tailored properties of the synthesized derivatives. The derivatives will be used for the synthesis of 3D hybrid materials by covalent linking of the 2D sheets joined with other organic and inorganic molecules, nanomaterials or biomacromolecules.

Call Details Starting Grant (StG), SH6, ERC-2020-STG
Summary ACADEMIA proposes a pioneering study of a neglected corpus of manuscripts stemming from the practice of quodlibetal debates held at Faculties of Arts of European universities, flourishing from the 14th to the early 16th century. As prescribed by the university statutes, dozens of professors participated periodically in these unique collective works of the Middle Ages, which encompassed all the disciplines pursued at the university, from logic to medicine to theology. The PI hypothesises that the professors presented at the hitherto mostly ignored quodlibets their recent scientific innovations, which they then published in the first collective volumes of European academia. The PI thus proposes a novel theoretical framework for understanding the quodlibets: they stand at the origin of the modern concept of science as a collective intellectual enterprise, similar to modern conferences and the subsequent dissemination of results. This makes them and their written form critical for understanding European intellectual and scientific traditions, both past and present. ACADEMIA’s ambition is to establish the corpus of these debates as a new field of study through an extensive examination of manuscripts, thus filling a substantial gap, radically extending the fields of the history of universities and intellectual history, and reconstructing the roots of the modern practice of fostering collective science. A complex analysis of the corpus will bring about a substantial change in our understanding of medieval practices of the production and sharing of knowledge. Aiming to examine the quodlibets as a phenomenon successively interconnecting European intellectual space, ACADEMIA focuses on fourteen universities at which the PI has identified the tradition so far and on their mutual relations and development. ACADEMIA employs an interdisciplinary team and an innovative combination of approaches from history, codicology, palaeography, philology, hermeneutics and Digital Humanities.

Call Details Consolidator Grant (CoG), PE6, ERC-2014-CoG
Summary The goal of the AI4REASON project is a breakthrough in what is considered a very hard problem in AI and automation of reasoning, namely the problem of automatically proving theorems in large and complex theories. Such complex formal theories arise in projects aimed at verification of today's advanced mathematics such as the Formal Proof of the Kepler Conjecture (Flyspeck), verification of software and hardware designs such as the seL4 operating system kernel, and verification of other advanced systems and technologies on which today's information society critically depends.
It seems extremely complex and unlikely to design an explicitly programmed solution to the problem. However, we have recently demonstrated that the performance of existing approaches can be multiplied by data-driven AI methods that learn reasoning guidance from large proof corpora. The breakthrough will be achieved by developing such novel AI methods. First, we will devise suitable Automated Reasoning and Machine Learning methods that learn reasoning knowledge and steer the reasoning processes at various levels of granularity. Second, we will combine them into autonomous self-improving AI systems that interleave deduction and learning in positive feedback loops. Third, we will develop approaches that aggregate reasoning knowledge across many formal, semi-formal and informal corpora and deploy the methods as strong automation services for the formal proof community.
The expected outcome is our ability to prove automatically at least 50% more theorems in high-assurance projects such as Flyspeck and seL4, bringing a major breakthrough in formal reasoning and verification. As an AI effort, the project offers a unique path to large-scale semantic AI. The formal corpora concentrate centuries of deep human thinking in a computer-understandable form on which deductive and inductive AI can be combined and co-evolved, providing new insights into how humans do mathematics and science.

Summary Mitochondria are often referred to as the “power houses” of eukaryotic cells. All eukaryotes were thought to have mitochondria of some form until 2016, when the first eukaryote thriving without mitochondria was discovered by our laboratory – a flagellate Monocercomonoides. Understanding cellular functions of these cells, which represent a new functional type of eukaryotes, and understanding the circumstances of the unique event of mitochondrial loss are motivations for this proposal. The first objective focuses on the cell physiology. We will perform a metabolomic study revealing major metabolic pathways and concentrate further on elucidating its unique system of iron-sulphur cluster assembly. In the second objective, we will investigate in details the unique case of mitochondrial loss. We will examine two additional potentially amitochondriate lineages by means of genomics and transcriptomics, conduct experiments simulating the moments of mitochondrial loss and try to induce the mitochondrial loss in vitro by knocking out or down genes for mitochondrial biogenesis. We have chosen Giardia intestinalis and Entamoeba histolytica as models for the latter experiments, because their mitochondria are already reduced to minimalistic “mitosomes” and because some genetic tools are already available for them. Successful mitochondrial knock-outs would enable us to study mitochondrial loss in ‘real time’ and in vivo. In the third objective, we will focus on transforming Monocercomonoides into a tractable laboratory model by developing methods of axenic cultivation and genetic manipulation. This will open new possibilities in the studies of this organism and create a cell culture representing an amitochondriate model for cell biological studies enabling the dissection of mitochondrial effects from those of other compartments. The team is composed of the laboratory of PI and eight invited experts and we hope it has the ability to address these challenging questions.

Project Accuracy and precision for molecular solids

Host Institution (HI) UNIVERZITA KARLOVA
Country Czechia
Call Details Starting Grant (StG), PE4, ERC-2017-STG
Summary The description of high pressure phases or polymorphism of molecular solids represents a significant scientific challenge both for experiment and theory. Theoretical methods that are currently used struggle to describe the tiny energy differences between different phases. It is the aim of this project to develop a scheme that would allow accurate and reliable predictions of the binding energies of molecular solids and of the energy differences between different phases.
To reach the required accuracy, we will combine the coupled cluster approach, widely used for reference quality calculations for molecules, with the random phase approximation (RPA) within periodic boundary conditions. As I have recently shown, RPA-based approaches are already some of the most accurate and practically usable methods for the description of extended systems. However, reliability is not only a question of accuracy. Reliable data need to be precise, that is, converged with the numerical parameters so that they are reproducible by other researchers.
Reproducibility is already a growing concern in the field. It is likely to become a considerable issue for highly accurate methods as the calculated energies have a stronger dependence on the simulation parameters such as the basis set size. Two main approaches will be explored to assure precision. First, we will develop the so-called asymptotic correction scheme to speed-up the convergence of the correlation energies with the basis set size. Second, we will directly compare the lattice energies from periodic and finite cluster based calculations. Both should yield identical answers, but if and how the agreement can be reached for general system is currently far from being understood for methods such as coupled cluster. Reliable data will allow us to answer some of the open questions regarding the stability of polymorphs and high pressure phases, such as the possibility of existence of high pressure ionic phases of water and ammonia.

Summary This proposal outlines an agenda that aims to improve our understanding of economies with inattentive agents. Attention to detail, not only to current news, but also to how the world works in general, is central to how we interact with the environment.
In the first part of the agenda, we will study how agents come up with the simplified mental models they use in their decision-making. The aim is to provide a new alternative to rational expectations. We will address the question of endogenous model uncertainty by sidestepping the largely statistical nature of previous work. Our agents learn about a model directly, i.e., all information on the details of the correct model is readily available. The envisioned implications can speak to issues such as the expectations formation and formation of narratives, polarization of opinions, and demand for public policy.
In the second part, we will study how a government optimally intervenes in markets if it finds it costly to get the necessary information. On one hand, a government does not possess the local information of decentralized markets. On the other, markets on their own often generate suboptimal social outcomes. We will explore what information the government should collect, how to use it for regulation, and when instead it should leave markets unaffected.
In the third part, we will leverage recent theories of attention allocation and use uniquely detailed data on attention and treatment choices by hospital personnel (including physicians and nurses). This will allow us to explore in more detail than before what theories describe realistic choices well. Moreover, we will eventually aim at a very practical goal: how to help clinicians decrease their cognitive load and improve medical choices.

Summary Why is the world green? Because predators control herbivores, allowing plants to flourish. This >50 years old answer to the deceptively simple question remains controversial. After all, plants are also protected from herbivores physically and by secondary chemistry. My goal is to test novel aspects of the “green world hypothesis”: ● How the importance of top-down effects varies with forest diversity and productivity along a latitudinal gradient? ● How the key predators, birds, bats and ants, contribute to top-down effects individually and in synergy? I strive to understand this because: ● While there is evidence that predators reduce herbivore abundance and enhance plant growth, the importance of top-down control is poorly understood across a range of forests. ● The importance of key predatory groups, and their antagonistic and synergic interactions, have been rarely studied, despite their potential impact on ecosystem dynamics in changing world. I wish to achieve my goals by: ● Factorial manipulations of key insectivorous predators (birds, bats, ants) to measure their effects on lower trophic levels in forest understories and canopies, accessed by canopy cranes, along latitudinal gradient spanning 75o from Australia to Japan. ● Studying compensatory effects among predatory taxa on herbivore and plant performance. Why this has not been done before: ● Factorial experimental exclusion of predatory groups replicated on a large spatial scale is logistically difficult. ● Canopy crane network along a latitudinal gradient has only recently become available. I am in excellent position to succeed as I have experience with ● foodweb experiments along an elevation gradient in New Guinea rainforests, ● study of bird, bat and arthropod communities. If the project is successful, it will: ● Allow understanding the importance of predators from temperate to tropical forests. ● Establish a network of experimental sites along a network of canopy cranes open for follow-up research.

Summary BEHAVFRICTIONS will use novel models focussing on information-processing frictions to explain choice patterns described in behavioral economics and psychology. The proposed research will provide microfoundations that are essential for (i) identification of stable preferences, (ii) counterfactual predictions, and (iii) normative conclusions.
(i) Agents who face information-processing costs must trade the precision of choice against information costs. Their behavior thus reflects both their stable preferences and the context-dependent procedures that manage their errors stemming from imperfect information processing. In the absence of micro-founded models, the two drivers of the behavior are difficult to disentangle for outside observers. In some pillars of the proposal, the agents follow choice rules that closely resemble logit rules used in structural estimation. This will allow me to reinterpret the structural estimation fits to choice data and to make a distinction between the stable preferences and frictions.
(ii) Such a distinction is important in counterfactual policy analysis because the second-best decision procedures that manage the errors in choice are affected by the analysed policy. Incorporation of the information-processing frictions into existing empirical methods will improve our ability to predict effects of the policies.
(iii) My preliminary results suggest that when an agent is prone to committing errors, biases--such as overconfidence, confirmatory bias, or perception biases known from prospect theory--arise under second-best strategies. By providing the link between the agent's environment and the second-best distribution of the perception errors, my models will delineate environments in which these biases shield the agents from the most costly mistakes from environments in which the biases turn into maladaptations. The distinction will inform the normative debate on debiasing.

Summary This project proposes a collaborative, ethnographic investigation of the relationship between three understudied subjects in anthropology: veterinary medicine, European hunting and wild boars. In recent decades, the wild boar has proliferated, (re)conquering the natural, rural and urban landscapes of Europe, and increasingly clashing with human practices and worlds. Classified as a game animal, the boar is primarily killed and managed by recreational hunters. Yet, hunters are proving incapable of stemming the tide of this intelligent, adaptable being, an interspecies relation that challenges hunting’s value and legitimacy in European society. This tension has amplified with the arrival of African Swine Fever (ASF) to the continent: a fatal virus that travels between wild boar and domestic pig, forest and farm, and threatens to infect and ruin the pig industry. In the name of biosecurity, and informed by veterinary knowledge, some States have intervened and conducted mass culls, erected dividing fences across Schengen space, or instituted no-go zones. During this crisis we witnessed how veterinary medicine’s role can extend beyond mediating human-animal relations, and work to structure and govern human lives in general. At the intersection of boars, hunting, ASF and veterinary medicine, this project has two main objectives: first, to examine how European hunting and porcine futures are intertwined, and the role of veterinarians in shaping these futures, and; second, through human-boar relations, study how society is becoming increasingly veterinarized and thus shape the conceptual and methodological development of the emerging field of veterinary anthropology. This project will further contribute to anthropology by opening a novel empirical and theoretical niche for the anthropology of hunting, and experiment with ethnography as a tool of engagement with near futures. The emerging and uncertain impact of ASF in Europe is an excellent moment to conduct such a project.
Summary
This project proposes a collaborative, ethnographic investigation of the relationship between three understudied subjects in anthropology: veterinary medicine, European hunting and wild boars. In recent decades, the wild boar has proliferated, (re)conquering the natural, rural and urban landscapes of Europe, and increasingly clashing with human practices and worlds. Classified as a game animal, the boar is primarily killed and managed by recreational hunters. Yet, hunters are proving incapable of stemming the tide of this intelligent, adaptable being, an interspecies relation that challenges hunting’s value and legitimacy in European society. This tension has amplified with the arrival of African Swine Fever (ASF) to the continent: a fatal virus that travels between wild boar and domestic pig, forest and farm, and threatens to infect and ruin the pig industry. In the name of biosecurity, and informed by veterinary knowledge, some States have intervened and conducted mass culls, erected dividing fences across Schengen space, or instituted no-go zones. During this crisis we witnessed how veterinary medicine’s role can extend beyond mediating human-animal relations, and work to structure and govern human lives in general. At the intersection of boars, hunting, ASF and veterinary medicine, this project has two main objectives: first, to examine how European hunting and porcine futures are intertwined, and the role of veterinarians in shaping these futures, and; second, through human-boar relations, study how society is becoming increasingly veterinarized and thus shape the conceptual and methodological development of the emerging field of veterinary anthropology.
