Summary I intend to investigate what cognitive mechanisms give us combinatorial speech. Combinatorial speech is the ability to make new words using pre-existing speech sounds. Humans are the only apes that can do this, yet we do not know how our brains do it, nor how exactly we differ from other apes. Using new experimental techniques to study human behavior and new computational techniques to model human cognition, I will find out how we deal with combinatorial speech.
The experimental part will study individual and cultural learning. Experimental cultural learning is a new technique that simulates cultural evolution in the laboratory. Two types of cultural learning will be used: iterated learning, which simulates language transfer across generations, and social coordination, which simulates emergence of norms in a language community. Using the two types of cultural learning together with individual learning experiments will help to zero in, from three angles, on how humans deal with combinatorial speech. In addition it will make a methodological contribution by comparing the strengths and weaknesses of the three methods.
The computer modeling part will formalize hypotheses about how our brains deal with combinatorial speech. Two models will be built: a high-level model that will establish the basic algorithms with which combinatorial speech is learned and reproduced, and a neural model that will establish in more detail how the algorithms are implemented in the brain. In addition, the models, through increasing understanding of how humans deal with speech, will help bridge the performance gap between human and computer speech recognition.
The project will advance science in four ways: it will provide insight into how our unique ability for using combinatorial speech works, it will tell us how this is implemented in the brain, it will extend the novel methodology of experimental cultural learning and it will create new computer models for dealing with human speech.

Project Active Wind Farms: Optimization and Control of Atmospheric Energy Extraction in Gigawatt Wind Farms

Summary With the recognition that wind energy will become an important contributor to the world’s energy portfolio, several wind farms with a capacity of over 1 gigawatt are in planning phase. In the past, engineering of wind farms focused on a bottom-up approach, in which atmospheric wind availability was considered to be fixed by climate and weather. However, farms of gigawatt size slow down the Atmospheric Boundary Layer (ABL) as a whole, reducing the availability of wind at turbine hub height. In Denmark’s large off-shore farms, this leads to underperformance of turbines which can reach levels of 40%–50% compared to the same turbine in a lone-standing case. For large wind farms, the vertical structure and turbulence physics of the flow in the ABL become crucial ingredients in their design and operation. This introduces a new set of scientific challenges related to the design and control of large wind farms. The major ambition of the present research proposal is to employ optimal control techniques to control the interaction between large wind farms and the ABL, and optimize overall farm-power extraction. Individual turbines are used as flow actuators by dynamically pitching their blades using time scales ranging between 10 to 500 seconds. The application of such control efforts on the atmospheric boundary layer has never been attempted before, and introduces flow control on a physical scale which is currently unprecedented. The PI possesses a unique combination of expertise and tools enabling these developments: efficient parallel large-eddy simulations of wind farms, multi-scale turbine modeling, and gradient-based optimization in large optimization-parameter spaces using adjoint formulations. To ensure a maximum impact on the wind-engineering field, the project aims at optimal control, experimental wind-tunnel validation, and at including multi-disciplinary aspects, related to structural mechanics, power quality, and controller design.

Summary Space exploration is one of boldest and most exciting endeavors that humanity has undertaken, and it holds enormous promise for the future. Our next challenges for the spatial conquest include bringing back samples to Earth by means of robotic missions and continuing the manned exploration program, which aims at sending human beings to Mars and bring them home safely. Inaccurate prediction of the heat-flux to the surface of the spacecraft heat shield can be fatal for the crew or the success of a robotic mission. This quantity is estimated during the design phase. An accurate prediction is a particularly complex task, regarding modelling of the following phenomena that are potential “mission killers:” 1) Radiation of the plasma in the shock layer, 2) Complex surface chemistry on the thermal protection material, 3) Flow transition from laminar to turbulent. Our poor understanding of the coupled mechanisms of radiation, ablation, and transition leads to the difficulties in flux prediction. To avoid failure and ensure safety of the astronauts and payload, engineers resort to “safety factors” to determine the thickness of the heat shield, at the expense of the mass of embarked payload. Thinking out of the box and basic research are thus necessary for advancements of the models that will better define the environment and requirements for the design and safe operation of tomorrow’s space vehicles and planetary probes for the manned space exploration. The three basic ingredients for predictive science are: 1) Physico-chemical models, 2) Computational methods, 3) Experimental data. We propose to follow a complementary approach for prediction. The proposed research aims at: “Integrating new advanced physico-chemical models and computational methods, based on a multidisciplinary approach developed together with physicists, chemists, and applied mathematicians, to create a top-notch multiphysics and multiscale numerical platform for simulations of planetary atmosphere entries, crucial to the new challenges of the manned space exploration program. Experimental data will also be used for validation, following state-of-the-art uncertainty quantification methods.”

Summary Rates of domestic violence and the relative risk of premature death for women are higher in sub-Saharan Africa than in any other region. Yet we know remarkably little about the economic forces, incentives and constraints that drive discrimination against women in this region, making it hard to identify policy levers to address the problem. This project will help fill this gap.
I will investigate gender discrimination from two complementary perspectives. First, through the lens of economic history, I will investigate the forces driving trends in women’s relative well-being since slavery. To quantify the evolution of well-being of sub-Saharan women relative to men, I will use three types of historical data: anthropometric indicators (relative height), vital statistics (to compute numbers of missing women), and outcomes of formal and informal family law disputes. I will then investigate how major economic developments and changes in family laws differentially affected women’s welfare across ethnic groups with different norms on women’s roles and rights.
Second, using intra-household economic models, I will provide new insights into domestic violence and gender bias in access to crucial resources in present-day Africa. I will develop a new household model that incorporates gender identity and endogenous outside options to explore the relationship between women’s empowerment and the use of violence. Using the notion of strategic delegation, I will propose a new rationale for the separation of budgets often observed in African households and generate predictions of how improvements in women’s outside options affect welfare. Finally, with first hand data, I will investigate intra-household differences in nutrition and work effort in times of food shortage from the points of view of efficiency and equity. I will use activity trackers as an innovative means of collecting high quality data on work effort and thus overcome data limitations restricting the existing literature

Project African river basins: catchment-scale carbon fluxes and transformations
Researcher (PI) Steven Bouillon
Host Institution (HI) KATHOLIEKE UNIVERSITEIT LEUVEN
Call Details Starting Grant (StG), PE10, ERC-2009-StG
Summary This proposal wishes to fundamentally improve our understanding of the role of tropical freshwater ecosystems in carbon (C) cycling on the catchment scale. It uses an unprecedented combination of state-of-the-art proxies such as stable isotope, 14C and biomarker signatures to characterize organic matter, radiogenic isotope signatures to determine particle residence times, as well as field measurements of relevant biogeochemical processes. We focus on tropical systems since there is a striking lack of data on such systems, even though riverine C transport is thought to be disproportionately high in tropical areas. Furthermore, the presence of landscape-scale contrasts in vegetation (in particular, C3 vs. C4 plants) are an important asset in the use of stable isotopes as natural tracers of C cycling processes on this scale. Freshwater ecosystems are an important component in the global C cycle, and the primary link between terrestrial and marine ecosystems. Recent estimates indicate that ~2 Pg C y-1 (Pg=Petagram) enter freshwater systems, i.e., about twice the estimated global terrestrial C sink. More than half of this is thought to be remineralized before it reaches the coastal zone, and for the Amazon basin this has even been suggested to be ~90% of the lateral C inputs. The question how general these patterns are is a matter of debate, and assessing the mechanisms determining the degree of processing versus transport of organic carbon in lakes and river systems is critical to further constrain their role in the global C cycle. This proposal provides an interdisciplinary approach to describe and quantify catchment-scale C transport and cycling in tropical river basins. Besides conceptual and methodological advances, and a significant expansion of our dataset on C processes in such systems, new data gathered in this project are likely to provide exciting and novel hypotheses on the functioning of freshwater systems and their linkage to the terrestrial C budget.

Project Architectural design In Dialogue with dis-Ability Theoretical and methodological exploration of a multi-sensorial design approach in architecture

Summary This research project is based on the notion that, because of their specific interaction with space, people with particular dis-abilities are able to appreciate spatial qualities or detect misfits in the environment that most architects—or other designers—are not even aware of. This notion holds for sensory dis-abilities such as blindness or visual impairment, but also for mental dis-abilities like autism or Alzheimer’s dementia. The experiences and subsequent insights of these dis-abled people, so it is argued, represent a considerable knowledge resource that would complement and enrich the professional expertise of architects and designers in general. This argument forms the basis for a methodological and theoretical exploration of a multi-sensorial design approach in architecture. On the one hand, a series of retrospective case studies will be conducted to identify and describe the motives and elements that trigger or stimulate architects’ attention for the multi-sensorial spatial experiences of people with dis-abilities when designing spaces. On the other hand, the research project will investigate experimentally in real time to what extent design processes and products in architecture can be enriched by establishing a dialogue between the multi-sensorial ‘knowing-in-action’ of people with dis-abilities and the expertise of professional architects/designers. In this way, the research project aims to develop a more profound understanding of how the concept of Design for All can be realised in architectural practice. At least as important, however, is its contribution to innovation in architecture tout court. The research results are expected to give a powerful impulse to quality improvement of the built environment by stimulating and supporting the development of innovative design concepts.

Summary Europe sits uncomfortably on the idea that there are no political and cultural alternatives credible enough to respond to the current uneasiness or malaise caused by both a world that is more and more non-European and a Europe that increasingly questions what is European about itself. This project will develop a new grounded theoretical paradigm for contemporary Europe based on two key ideas: the understanding of the world by far exceeds the European understanding of the world; social, political and institutional transformation in Europe may benefit from innovations taking place in regions and countries with which Europe is increasingly interdependent. I will pursue this objective focusing on four main interconnected topics: democratizing democracy, intercultural constitutionalism, the other economy, human rights (right to health in particular).
In a sense that the European challenges are unique but, in one way or another, are being experienced in different corners of the world. The novelty resides in bringing new ideas and experiences into the European conversation, show their relevance to our current uncertainties and aspirations and thereby contribute to face them with new intellectual and political resources. The usefulness and relevance of non-European conceptions and experiences un-thinking the conventional knowledge through two epistemological devices I have developed: the ecology of knowledges and intercultural translation. By resorting to them I will show that there are alternatives but they cannot be made credible and powerful if we go on relying on the modes of theoretical and political thinking that have dominated so far. In other words, the claim put forward by and worked through this project is that in Europe we don’t need alternatives but rather an alternative thinking of alternatives.

Project Friction stir processing based local damage mitigation and healing in aluminium alloys
Researcher (PI) Aude SIMAR
Host Institution (HI) UNIVERSITE CATHOLIQUE DE LOUVAIN
Call Details Starting Grant (StG), PE8, ERC-2016-STG
Summary ALUFIX proposes an original strategy for the development of aluminium-based materials involving damage mitigation and extrinsic self-healing concepts exploiting the new opportunities of the solid-state friction stir process. Friction stir processing locally extrudes and drags material from the front to the back and around the tool pin. It involves short duration at moderate temperatures (typically 80% of the melting temperature), fast cooling rates and large plastic deformations leading to far out-of-equilibrium microstructures. The idea is that commercial aluminium alloys can be locally improved and healed in regions of stress concentration where damage is likely to occur. Self-healing in metal-based materials is still in its infancy and existing strategies can hardly be extended to applications. Friction stir processing can enhance the damage and fatigue resistance of aluminium alloys by microstructure homogenisation and refinement. In parallel, friction stir processing can be used to integrate secondary phases in an aluminium matrix. In the ALUFIX project, healing phases will thus be integrated in aluminium in addition to refining and homogenising the microstructure. The “local stress management strategy” favours crack closure and crack deviation at the sub-millimetre scale thanks to a controlled residual stress field. The “transient liquid healing agent” strategy involves the in-situ generation of an out-of-equilibrium compositionally graded microstructure at the aluminium/healing agent interface capable of liquid-phase healing after a thermal treatment. Along the road, a variety of new scientific questions concerning the damage mechanisms will have to be addressed.

Project How anxiety transforms human cognition: an Affective Neuroscience perspective

Host Institution (HI) UNIVERSITEIT GENT
Call Details Starting Grant (StG), SH3, ERC-2007-StG
Summary Anxiety, a state of apprehension or fear, may provoke cognitive or behavioural disorders and eventually lead to serious medical illnesses. The high prevalence of anxiety disorders in our society sharply contrasts with the lack of clear factual knowledge about the corresponding brain mechanisms at the origin of this profound change in the appraisal of the environment. Little is known about how the psychopathological state of anxiety ultimately turns to a medical condition. The core of this proposal is to gain insight in the neural underpinnings of anxiety and disorders related to anxiety using modern human brain-imaging such as scalp EEG and fMRI. I propose to enlighten how anxiety transforms and shapes human cognition and what the neural correlates and time-course of this modulatory effect are. The primary innovation of this project is the systematic use scalp EEG and fMRI in human participants to better understand the neural mechanisms by which anxiety profoundly influences specific cognitive functions, in particular selective attention and decision-making. The goal of this proposal is to precisely determine the exact timing (using scalp EEG), location, size and extent (using fMRI) of anxiety-related modulations on selective attention and decision-making in the human brain. Here I propose to focus on these two specific processes, because they are likely to reveal selective effects of anxiety on human cognition and can thus serve as powerful models to better figure out how anxiety operates in the human brain. Another important aspect of this project is the fact I envision to help bridge the gap in Health Psychology between fundamental research and clinical practice by proposing alternative revalidation strategies for human adult subjects affected by anxiety-related disorders, which could directly exploit the neuro-scientific discoveries generated in this scientific project.

Host Institution (HI) KATHOLIEKE UNIVERSITEIT LEUVEN
Call Details Starting Grant (StG), SH6, ERC-2009-StG
Summary In this project, innovative techniques to reconstruct ancient economies are developed and new insights in the trade and processing of mineral raw materials are gained based on interdisciplinary archaeological and archaeometrical research. An innovative methodology for and a practical provenance database of the primary origin of natron glass from the Hellenistic-Roman world will be established. The project investigates both production and consumer sites of glass raw materials using both typo-chronological and archaeometrical (isotope geochemical) study of finished glass artefacts at consumer sites as well as mineralogical and chemical characterisation of raw glass and mineral resources at primary production sites. Suitable sand resources in the locations described by ancient authors will be identified through geological prospecting on the basis of literature review and field work. Sand and flux (natron) deposits will be mineralogically and geochemically characterised and compared to the results of the archaeological and geochemical investigations of the glass. Through integrated typo-chronological and archaeometrical analysis, the possible occurrence of primary production centres of raw glass outside the known locations in Syro-Palestine and Egypt, particularly in North-Africa, Italy, Spain and Gaul will be critically studied. In this way, historical, archaeological and archaeometrical data are combined, developing new interdisciplinary techniques for innovative archaeological interpretation of glass trade in the Hellenistic-Roman world.

Suitable sand resources in the locations described by ancient authors will be identified through geological prospecting on the basis of literature review and field work. Sand and flux (natron) deposits will be mineralogically and geochemically characterised and compared to the results of the archaeological and geochemical investigations of the glass. Through integrated typo-chronological and archaeometrical analysis, the possible occurrence of primary production centres of raw glass outside the known locations in Syro-Palestine and Egypt, particularly in North-Africa, Italy, Spain and Gaul will be critically studied. In this way, historical, archaeological and archaeometrical data are combined, developing new interdisciplinary techniques for innovative archaeological interpretation of glass trade in the Hellenistic-Roman world.
