Summary "The A2C2 project treats two major challenges in climate and atmospheric research: the time dependence of the climate attractor to external forcings (solar, volcanic eruptions and anthropogenic), and the attribution of extreme climate events occurring in the northern extra-tropics. The main difficulties are the limited climate information, the computer cost of model simulations, and mathematical assumptions that are hardly verified and often overlooked in the literature.
A2C2 proposes a practical framework to overcome those three difficulties, linking the theory of dynamical systems and statistics. We will generalize the methodology of flow analogues to multiple databases in order to obtain probabilistic descriptions of analogue decompositions.
The project is divided into three workpackages (WP). WP1 embeds the analogue method in the theory of dynamical systems in order to provide a metric of an attractor deformation in time. The important methodological step is to detect trends or persisting outliers in the dates and scores of analogues when the system yields time-varying forcings. This is done from idealized models and full size climate models in which the forcings (anthropogenic and natural) are known.
A2C2 creates an open source toolkit to compute flow analogues from a wide array of databases (WP2). WP3 treats the two scientific challenges with the analogue method and multiple model ensembles, hence allowing uncertainty estimates under realistic mathematical hypotheses. The flow analogue methodology allows a systematic and quasi real-time analysis of extreme events, which is currently out of the reach of conventional climate modeling approaches.
The major breakthrough of A2C2 is to bridge the gap between operational needs (the immediate analysis of climate events) and the understanding long-term climate changes. A2C2 opens new research horizons for the exploitation of ensembles of simulations and reliable estimates of uncertainty."

Project Elucidating the Causes and Effects of Atlantic Circulation Changes through Model-Data Integration
Researcher (PI) Claire Waelbroeck
Host Institution (HI) CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE CNRS
Call Details Advanced Grant (AdG), PE10, ERC-2013-ADG
Summary Rapid changes in ocean circulation and climate have been observed in marine sediment and ice cores, notably over the last 60 thousand years (ky), highlighting the non-linear character of the climate system and underlining the possibility of rapid climate shifts in response to anthropogenic greenhouse gas forcing.
To date, these rapid changes in climate and ocean circulation are still not fully explained. Two main obstacles prevent going beyond the current state of knowledge:
- Paleoclimatic proxy data are by essence only indirect indicators of the climatic variables, and thus can not be directly compared with model outputs;
- A 4-D (latitude, longitude, water depth, time) reconstruction of Atlantic water masses over the past 40 ky is lacking: previous studies have generated isolated records with disparate timescales which do not allow the causes of circulation changes to be identified.
Overcoming these two major limitations will lead to major breakthroughs in climate research. Concretely, I will create the first database of Atlantic deep-sea records over the last 40 ky, and extract full climatic information from these records through an innovative model-data integration scheme using an isotopic proxy forward modeling approach. The novelty and exceptional potential of this scheme is twofold: (i) it avoids hypotheses on proxy interpretation and hence suppresses or strongly reduces the errors of interpretation of paleoclimatic records; (ii) it produces states of the climate system that best explain the observations over the last 40 ky, while being consistent with the model physics.
Expected results include:
• The elucidation of the mechanisms explaining rapid changes in ocean circulation and climate over the last 40 ky,
• Improved climate model physics and parameterizations,
• The first projections of future climate changes obtained with a model able to reproduce the highly non linear behavior of the climate system observed over the last 40 ky.

Call Details Advanced Grant (AdG), SH4, ERC-2011-ADG_20110406
Summary Listening in realistic situations is an active process that engages perceptual and cognitive faculties, endowing speech with meaning, music with joy, and environmental sounds with emotion. Through hearing, humans and other animals navigate complex acoustic scenes, separate sound mixtures, and assess their behavioral relevance. These remarkable feats are currently beyond our understanding and exceed the capabilities of the most sophisticated audio engineering systems. The goal of the proposed research is to investigate experimentally a novel view of hearing, where active hearing emerges from a deep interplay between adaptive sensory processes and goal-directed cognition. Specifically, we shall explore the postulate that versatile perception is mediated by rapid-plasticity at the neuronal level. At the conjunction of sensory and cognitive processing, rapid-plasticity pervades all levels of auditory system, from the cochlea up to the auditory and prefrontal cortices. Exploiting fundamental statistical regularities of acoustics, it is what allows humans and other animal to deal so successfully with natural acoustic scenes where artificial systems fail. The project builds on the internationally recognized leadership of the PI in the fields of physiology and computational modeling, combined with the expertise of the Co-Investigator in psychophysics. Building on these highly complementary fields and several technical innovations, we hope to promote a novel view of auditory perception and cognition. We aim also to contribute significantly to translational research in the domain of signal processing for clinical hearing aids, given that many current limitations are not technological but rather conceptual. The project will finally result in the creation of laboratory facilities and an intellectual network unique in France and rare in all of Europe, combining cognitive, neural, and computational approaches to auditory neuroscience.

Host Institution (HI) FONDATION NATIONALE DES SCIENCES POLITIQUES
Call Details Advanced Grant (AdG), SH2, ERC-2010-AdG_20100407
Summary "AIME is an inquiry to make more precise what is lumped together into the confusing word ""modernization"". The work done in the field of science studies (STS) on the progress and practice of science and technology has had the consequence of deeply modifying the definition of ""modernity"", resulting into the provocative idea that ""we (meaning the Europeans) have never been modern"". This is, however only a negative definition. To obtain a positive rendering of the European current situation, it is necessary to start an inquiry in the complex and conflicting set of values that have been invented. This inquiry is possible only if there is a clear and shareable way to judge the differences in the set of truth-conditions that make up those conflicting sets of values. AIME offers a grammar of those differences based on the key notion of modes of existence. Then it builds a procedure and an instrument to test this grammar into a selected set of situations where the definitions of the differing modes of existence is redefined and renegotiated. The result is a set of shareable definitions of what modernization has been in practice. This is important just at the moment when Europe has lost its privileged status and needs to be able to present itself in a new ways to the other cultures and civilizations which are making up the world of globalization with very different views on what it is to modernize themselves."

Summary The scientific motivation of this project is the significant presence of organic compounds at the surface of the ocean. They form the link between ocean biogeochemistry through the physico-chemical processes near the water-air interface with primary and secondary aerosol formation and evolution in the air aloft and finally to the climate impact of marine boundary layer aerosols. However, their photochemistry and photosensitizer properties have only been suggested and discussed but never fully addressed because they were beyond reach. This project suggests going significantly beyond this matter of fact by a combination of innovative tools and the development of new ideas.
This project is therefore devoted to new laboratory investigations of processes occurring at the air sea interface to predict emission, formation and evolution of halogenated radicals and aerosols from this vast interface between oceans and atmosphere. It progresses from fundamental laboratory measurements, marine science, surface chemistry, photochemistry … and is therefore interdisciplinary in nature.
It will lead to the development of innovative techniques for characterising chemical processing at the air sea interface (e.g., a multiphase atmospheric simulation chamber, a time-resolved fluorescence technique for characterising chemical processing at the air-sea interface). It will allow the assessment of new emerging ideas such as a quantitative description of the importance of photosensitized reactions in the visible at the air/sea interface as a major source of halogenated radicals and aerosols in the marine environment.
This new understanding will impact on our ability to describe atmospheric chemistry in the marine environment which has strong impact on the urban air quality of coastal regions (which by the way represent highly populated regions ) but also on climate change by providing new input for global climate models.

Project Beasts to Craft: BioCodicology as a new approach to the study of parchment manuscripts
Researcher (PI) Matthew COLLINS
Host Institution (HI) KOBENHAVNS UNIVERSITET
Call Details Advanced Grant (AdG), SH6, ERC-2017-ADG
Summary The intention of Beasts to Craft (B2C) is to document the biological and craft records in parchment in order to reveal the entangled histories of animal improvement and parchment production in Europe from 500-1900 AD.
B2C will lay the foundations for a new approach to the the study of parchment manuscripts —biocodicology— which draws evidence from the overlooked first stages in production, the raising of livestock and the preparation of the skins.
1. Parchment is an extraordinary but overlooked high resolution zooarchaeological record and a molecular archive. Livestock genetics is revealing breed diversity and markers of character traits such as fleece quality. B2C will exploit this new-found knowledge, using progressively older dated archival (sheep) parchments to study the history of improvement 1300 - 1900. Visual examination of the skins will search for direct evidence of disease and fleece quality.
2. Craft skills can be read from parchment and, when combined with chemical data and comparison with modern analogues, will produce the first European wide record of the craft from 500-1900. The size and scope of this the parchment archive means it is one of the largest and most highly resolved records of a specialist medieval craft. We will explore how these skills develop and when and where regional patterns appear and decline.
These two remarkable records requires a large interdisciplinary team. However biocodicology draws from and informs upon a wide and diverse spectrum of existing scholarship in conservation, the arts and sciences. A third strand of the project will (i) furnish manuscript scholars with some of the information available to the scribe at time of production (ii) inform and shape attitudes to parchment conservation (iii) provide high resolution biological data on animal management, movement and health and (iv) explore methods to link datasets and promote data reuse.

Summary Infant is the most powerful learner: He learns in a few months to master language, complex social interactions, etc. Powerful statistical algorithms, simultaneously acting at the different levels of functional hierarchies have been proposed to explain learning. I propose here that two other elements are crucial. The first is the particular human cerebral architecture that constrains statistical computations. The second is the human’s ability to access a rich symbolic system. I have planned 6 work packages using the complementary information offered by non-invasive brain-imaging techniques (EEG, MRI and optical topography) to understand the neural bases of infant statistical computations and symbolic competence from 6 months of gestation up until the end of the first year of life.
WP1 studies from which preterm age, statistical inferences can be demonstrated using hierarchical auditory oddball paradigms.
WP2 investigates the consequences of a different pre-term environment (in-utero versus ex-utero) on the early statistical computations in the visual and auditory domains and their consequences on the ongoing brain activity along the first year of life.
WP3 explores the neural bases of how infants infer word meaning and word category, and in particular the role of the left perisylvian areas and of their particular connectivity.
WP4 questions infant symbolic competency. I propose several criteria (generalization, bidirectionality, use of algebraic rules and of logical operations) tested in successive experiments to clarify infant symbolic abilities during the first semester of life.
WP5-6 are transversal to WP1-4: WP5 uses MRI to obtain accurate functional localization and maturational markers correlated with functional results. In WP6, we develop new tools to combine and analyse multimodal brain images.
With this proposal, I hope to clarify the specificities of a neural functional architecture that are critical for human learning from the onset of cortical circuits.

Summary From testicular grafting (1920s) to step counting watches (2014), the perceptions and practices of health seeking individuals have been marked by continuities and profound changes during a twentieth century largely shaped by the advent of a communication society. Visuals can be a source to understand transformations by postulating an interactive, performative power of mass media in societies. Which roles did visuals play in changes from public health and human capital collective understandings of the healthy self to new (sometimes debated) perceptions and practices of our bodies as forms of individual capital in an increasing market-economized world?
Pursuing these questions, the project focuses on four fields of investigation -food/nutrition; movement/exercise/sports; sexuality/reproduction/infants and dependency/addiction/overconsumption- in Germany, France and Great Britain studied with an entangled history framework.
Within this scope the project aims at understanding (1)how visuals shape our health related self-understandings and practices in a continuity/discontinuity from the bio-political to the bio-economic logic. (2) The project will explore and explain how and why understandings of body capital differ or overlap in European countries. (3) The project will analyse if and how visual media serve as a promotion-communication hyphen for twentieth century preventive-self understanding.
With a visual perspective on a long twentieth century, the project seeks to better understand changes and continuities in the history of health intertwined with the history of media. This will provide new insights into how the internalization of bodycapital has evolved throughout the past century, how transformations in the media world (from film to TV to internet) play out at the individual level and how health challenges and cultural differences in body perceptions and practices persist in producing social distinction in an age of global information and advanced health systems.

Summary "During their first year of life, infants become attuned to the phonemes, words and phonological rules of their language, with little or no adult supervision. After 30 years of accumulated experimental results, we are still lacking an account for the puzzling fact that these 3 interdependent components of language are acquired not sequentially, but in parallel. Drawing tools from Machine Learning and Automatic Speech Recognition, we construct a model of this early process, test it on 2 large spontaneous speech databases (Japanese, French and Dutch) and test its predictions in infants using behavioral, EEGs and fNIRS techniques.
1. Coding. We study different ways of defining coding features for speech, from fine-grained to coarse grained, in view of the automatic discovery of a hierarchy of linguistic units. We compare this with a systematic study of the units of speech coding as they unfold in 6, 9 and 12 month old infants..
2. Lexicon. Infants recognize some words before they know the phonemes of their language; we modify existing word segmentation algorithms so they can work on raw speech. We test the unique prediction that infants start with a large lexicon that’s quite different from the adult one.
3. Rules. Phonemes are produced as overlapping, coarticulated gestures. To untangle these context effects, we use a predictive model of coarticulation in auditory space and invert it. We test when and how infants perform reverse coarticulation.
4. Integration. The above subprojects provide only an initial bootstrapping into approximate phonemes, words, and contextual rules. We show how to iteratively integrate these approximate representations to derive better ones. The outcome will be numerically assessed on an adult directed and infant directed speech database, and compared to those of to state-of-the-art supervized phoneme recognizers. The predictions will be tested in infants learning artificial languages and in a longitudinal study."

Project Brain-viscera interactions underlie subjectivity

Host Institution (HI) ECOLE NORMALE SUPERIEURE
Call Details Advanced Grant (AdG), SH4, ERC-2014-ADG
Summary Subjectivity defines the subject who is perceiving, feeling, thinking, acting, and is essential to understand the conscious mind from the inside. However, subjectivity, or non-reflective first-person perspective, is not identified as a core concept in cognitive neuroscience and its neural basis remain largely unknown. BRAVIUS offers a unified framework to appraise both the concept and the neural mechanisms generating subjectivity. The hypothesis relies on two vital organs that generate their own rhythmic electrical activity, the stomach and the heart, and therefore constantly send information up to the neocortex, even in the absence of bodily change. Cortical responses to those visceral organs would define the organism as an entity at the neural level, and create a subject-centered referential from which first-person perspective can develop. In other words, the cardiac and gastric pacemakers could feed the brain with self-specifying inputs. BRAVIUS builds on previous theories and studies on visceral states but focuses on ascending information, from viscera to brain, and does not require visceral states to change nor to be consciously perceived. Experimentally, BRAVIUS measures the understudied neural response evoked by heartbeats and introduces a new measure, the electrogastrogram, to quantify the slow gastric pacemaker. BRAVIUS will test with magneto-encephalography (MEG) the role of neural responses to ascending visceral signals in generating subjectivity by cutting across domains of cognitive sciences and exploring diverse paradigms where subjectivity is engaged: perceptual consciousness, self-consciousness, emotions and decision making. BRAVIUS will further explore how cardiac and gastric ascending signals shape the temporal (MEG) and spatial (fMRI) organization of spontaneous brain activity. The project outcome is a detailed mechanistic neural account of the most private part of the human mind, and a unified concept of subjectivity across cognitive domains.
Summary
Subjectivity defines the subject who is perceiving, feeling, thinking, acting, and is essential to understand the conscious mind from the inside. However, subjectivity, or non-reflective first-person perspective, is not identified as a core concept in cognitive neuroscience and its neural basis remain largely unknown. BRAVIUS offers a unified framework to appraise both the concept and the neural mechanisms generating subjectivity. The hypothesis relies on two vital organs that generate their own rhythmic electrical activity, the stomach and the heart, and therefore constantly send information up to the neocortex, even in the absence of bodily change. Cortical responses to those visceral organs would define the organism as an entity at the neural level, and create a subject-centered referential from which first-person perspective can develop. In other words, the cardiac and gastric pacemakers could feed the brain with self-specifying inputs.
