The WE-COOP project shifts our traditional androcentric perspective on workplace democracy by investigating the labour experiences of women in worker cooperatives. Studied for their high potential in the democratization of labour relations, worker cooperatives have been systematically considered as a site for class struggle only. WE-COOP excavates how and why worker cooperatives are also a locus where yet unexplored sets of representations, practices and justifications pertaining to women’s emancipation and gender equality at work are produced. Opening a whole new field of enquiry crisscrossing the topics of gender, labour, and democracy, the project addresses two series of questions that cover, respectively, women’s visibility and voice. First, to what extent and how does the democratic apparatus of worker cooperatives allow women to reconfigure labour according to their needs and problems, to re-evaluate the traditional separation between the public and private sphere and to redefine political imaginaries pertaining to their emancipation at work? Second, are there gender-differentiated scripts of cooperative labour and if so, how can they expand our understanding of workplace democracy towards more inclusive analytical frameworks? Focusing on the case-study of France, the project is based on a multi-layered survey of worker cooperatives as well as rare forms of all-women cooperative experiments. It combines quantitative and qualitative methods with an innovative Participatory Research in four incremental steps, allowing for the appropriation by women workers of their narratives and struggles. By unfolding the visibility and voice of women workers, WE-COOP will contribute to the ongoing research on participatory methodologies, produce an unprecedented digital narrative archive on cooperative labour fuelling further research, expand our knowledge on gender-differentiated scripts of workplace democracy while opening a new field of inquiry on feminist utopias at work.

What makes a piece of information personally engaging, and what does it even mean when it is experienced as such? Adopting a child-centred view on an emergent form of literate life, I will investigate what imaginative experiences fuel the current boom of children’s nonfiction picturebooks (CNPs). How do these books make children imagine, that is, shift their perception of the sensory world and oneself? What niche may they come to occupy in children’s day-to-day dealings with information? Contemporary society’s ‘strong reader’ is a fiction lover; a child who indulges in formal learning materials is a ‘prolific student.’ Most readers aged 9-11 are neither but many occasionally devour fun facts, sometimes on highly specialist topics. CNPs have skyrocketed recently but, in contrast to fiction, we have no conceptual tools for grasping the imaginative and generally affective experiences nonfiction elicits. Engaging children, parents, authors, and other actors, WONDRE will redress the gap. I will lead a team of social science (literacy, media literacy, childhood) and humanities (literature) scholars, straddling both worlds myself and drawing on my further expertise in imagining and cognition. We will combine focus groups, interviews, surveys, text-image analyses, and Q studies, radically enhancing a method mix that I have begun developing in my prior work on children’s embodied experiences of fiction. This research showed a fiction bias in children’s construal of ‘being a reader.’ It hinted that nonfiction can prompt imaginings as compelling as fiction but also that children who prefer nonfiction may differ from fiction fans in how they sustain their imagining via other texts, props, activities. WONDRE will also yield a multilingual digital CNP on reading that will be co-created by participants and art students, aiming to empower diverse young readers and collectively unravel how information relates to imagining in the most vulnerable stages of literacy development.

Have you ever had that moment where you reach for something, convinced it is heavy, but it is actually light? Your arm jolts upward, correcting itself before you realise the difference. This split second adjustment is thanks to your cerebellum, the part of your brain responsible for fine-tuning movements by integrating sensory feedback. While the cerebellum is traditionally associated with motor control, it plays a similar role in cognitive functions. Despite occupying 10% of the brain’s volume, the cerebellum houses more than 50% of its neurons, many of which are integral to higher cognitive processes. Its extensive connections with brain regions responsible for complex thought and emotion make it a promising target for non-invasive brain stimulation (NIBS) especially in addressing the resistant cognitive and negative symptoms observed in psychiatric disorders such as schizophrenia, bipolar disorder, and autism. However, a significant challenge persists: clinical research on NIBS often relies on a trial-and-error approach, while fundamental research has yet to fully translate electrophysiological findings into circuit-level applications that can guide clinical interventions. To bridge this gap, I will develop normative models from large-scale MRI cohorts to identify patients who are most likely to benefit from cerebellar stimulation and then derive a personalised cerebellar target. Concurrently, animal studies using ultra-high field MRI will be conducted to determine optimal cerebellar stimulation parameters. With intracranial recordings, I will explore the neuroplastic changes induced by NIBS in humans. The project will culminate in a proof-of-concept clinical trial aiming at improving cognitive and negative symptoms across schizophrenia, bipolar disorder and autism with cerebellar NIBS. This multidisciplinary project has the potential to revolutionize the treatment of resistant psychiatric symptoms and catalyse advancements in the understanding of NIBS.

A defossilized global energy ecosystem hinges on efficient conversion between renewable electrical energy and chemical energy stored in molecules. This conversion requires precious catalysts to drive relevant reactions at practical rates. Many catalysts are employed in the form of nanoparticles (NP) dispersed on support materials. All relevant reactions occur in a nanoscale region at the interface between the solid catalyst and an electrolyte solution, i.e., an electric double layer (EDL). Our current knowledge of EDL is essentially limited to planar electrodes with a single EDL, whereas supported NP catalysts (SNPC) exhibit radically different EDL characteristics, featuring overlap of individual EDLs around the NPs and the adjacent support material. This knowledge gap, concerning crucial local reaction conditions within the EDL, prevents effectively transferring knowledge obtained at planar electrodes to performance improvements of SNPC. MESO-CAT aims at launching the mesoscopic (1~100 nm) science of overlapping EDLs in SNPC and unravelling the influence of overlapping EDLs on structure-activity relationship of SNPC. MESO-CAT will address three foundational questions in electrocatalysis of SNPC using theoretical methods in an interaction loop with experimentalists. First, how are the overlapping EDLs formed under realistic conditions? This will be studied using a unique theoretical approach for mesoscale EDLs with both quantum mechanical electrons and classical electrolyte particles treated on equal footing. Second, how do overlapping EDLs influence elementary electron transfer kinetics? This will be unravelled using a model Hamiltonian for proton-coupled electron transfer considering various EDL effects. Third, how do overlapping EDLs influence the overall structure-activity relationship? This will lay the groundwork for transformative advancements in electrochemical energy conversion via regulating the mesoscale EDL effects.

Urban aerosol particles are one of the largest human health hazards globally. A significant fraction of urban aerosol is secondary, .i.e., formed via atmospheric chemical reactions of emitted trace gases, with secondary organic aerosol (SOA) driving health impacts in urban air. Decades of air quality regulations have substantially reduced the motor vehicle emissions of organic compounds that act as precursors to SOA pollution. In my recent studies, we show for the first time that volatile chemical products (VCPs) from household chemicals are becoming one of the largest sources of organic vapors in US cities. Based on their chemical properties, the potential of VCPs to form SOA is expected to be high but is as yet unknown. With chemical transport models showing a general shortfall in predicting urban SOA, VCPs are anticipated to be the missing source to bridge this long-standing knowledge gap. The aim of CHANEL is to provide unprecedented data to resolve the urban SOA pollution puzzle and identify the key VCP precursors to aerosol pollution. Using recent advances in state-of-the-art chemical ionization mass spectrometry, we will perform field measurements in European urban areas to determine the chemical composition of VCP emissions. A Zeppelin will be used as an airborne platform to probe the urban “breath” of European cities and quantify the chemical evolution and SOA production from VCPs downwind of urban centers. These measurements will be accompanied by controlled atmospheric simulation chamber experiments to oxidize VCP emissions and retrieve their SOA yields as a parametrization to be used by chemical transport models. In a future of electrified fleets where fossil fuel emissions are expected to further decrease and VCPs will dominate urban air pollution, CHANEL will push the frontiers of knowledge on urban SOA pollution and set the basis for future efficient adaptation policies.

Equations of waves and flows are used extensively in physics and biology, to describe phenomena ranging from the flow past an airfoil, to the collective motion of cells and to the motion of water surface. A major issue is to explain how the propagation through space and the concentration to various scales can emerge from these mathematical models. Fundamental progress have been made since the beginning of the millenium around the role played by specific solutions that either propagate or shrink while keeping the same shape, such as solitary waves for example. These specific solutions are the key to understand the global dynamics. The goal of this project is to push forward the current knowledge on their stability, their emergence over time, and the dynamics they are responsible in several equations. The FloWAS project will study seemingly unrelated models, whose solutions in fact display remarkably close behaviours.  First, we aim at describing how a thin layer of fluid can detach off a boundary and be ejected away in a stream. This is a key phenomenon to understand the drag exerted on moving objects. For this we will study singular solutions of the unsteady Prandtl system of fluid mechanics. Second, we will study concentration phenomena arising in the movement of bacteria. For that we will consider nonlinear structures appearing in the Keller-Segel system: how they can collapse, and how they can interact. Third, we will consider how, from initially disordered wave packets, order appears over time and traveling waves emerge. This study will be made on the critical wave equation. Applications to weak wave turbulence will be pursued. Describing all these phenomena lies at the frontier of current research, and we expect applications to a wide range of models.

Quantum Electrodynamics (QED) is the theory that unifies electromagnetism and quantum mechanics to describe how light and matter interact. Considered as one of the most accurately tested theories, it led Richard Feynman to call it “the jewel of physics”. Yet, in the strong-field (SF) regime, when the light fields are ultra-intense, this theory is only treated perturbatively and the non-perturbative regime of SF-QED remains a terra incognita as even no theory exists to predict the behaviour of nature. The advent of multi-PW laser infrastructures now makes the SF-QED regime within experimental reach when considering the collision of relativistic electrons with such light pulses focused above 10^22W/cm2. Yet, all planned experiments to probe SF-QED with current technologies only propose to investigate its perturbative regime, expected to be well described by theory.  In the EXAFIELD project, I propose a new concept of experiments to exceed the perturbative limit of SF-QED in the lab. This will be achieved by reflecting an ultra-intense laser pulse off a plasma mirror at relativistic speed. The strong Doppler effect occurring upon reflection up-converts the near-infrared laser pulse down to the extreme ultraviolet range which enables both temporal compression to the attosecond timescale and spatial compression down to sub-micron size. This results in a considerable intensity boost at focus of more than three orders of magnitude up to a few-10^25W/cm2.  The collision of such a “Doppler-boosted beam” with ultrashort electron bunches generated from laser-plasma accelerators will allow us to access regimes where the SF-QED can no longer be treated perturbatively, producing very strong signatures in the lab. Characterizing how the observations deviate from the perturbative theory will enable us to determine the limits of validity of the perturbative models and will open to a new area of research toward the understanding of the non-perturbative regime of SF-QED.

The emergenceThe emergence of an agropastoral way of life in South West Asia from the late 10th millennium BCE revolutionised the social organisation of prehistoric communities. The spread of this new economic and cultural model followed several trajectories. A key region comprised between the Zagros mountains of the Iranian Plateau to the Indus Valley in the plains of Pakistan, known as Indo-Iranian borderlands (IIBL), is yet poorly explored. Current knowledge of agropastoralism dynamics and dispersal in this area remains fragmentary due to the lack of a robust chronological frame drawing temporal links between the settlements. The AgroChrono project particularly explores the development of agropastoralism among agropastoral societies of the 7th to 4th millennium BCE in the IIBL around four research themes: (i) The chronology to resolve the time frame of early agropastoral occupations in this region; (ii) The economy to document human subsistence practices with the exploitation of domestic resources; (iii) The palaeoenvironment setting and variations that may have influenced the settlement patterns and availability of natural resources necessary for their subsistence; (iv) The cultural and economic links between the various settlements by gathering all the archaeological datasets available. All these aspects are investigated using a combination of classical archaeological, bioarchaeological and palaeoenvironmental methods, together with the latest developments in biomolecular, isotopic and chronometric techniques. It particularly includes the next stage of development for compound-specific radiocarbon analyses of archaeological and environmental matrices, a state-of-the-art method essential for resolving the local problematics regarding the chronology. All the generated data will be modelled to test various scenarios on the emergence of agropastoralism in the IIBL and to determine if this resulted from a single cultural diffusion or local independent trajectories.

Long gamma-ray bursts (LGRBs) are the most violent explosions in the Universe after the Big Bang, occurring during the collapse of a massive star that leaves behind a newly formed compact object and launches powerful relativistic jets. At more than 55 years from their discovery, the mechanism responsible for the electromagnetic emission of LGRBs remains unclear, just as the nature of the accreting compact object that powers them up. The huge scale separation between different processes (the gravitational collapse and the onset of the supernova, the propagation of the jet through the star, and the production of high-energy emission from the jet at large distances) usually forces theoretical and numerical models to focus on a specific stage of the LGRB, rather than considering them all at once. To this day, there are two fundamental questions that remain unanswered: - What is the main prompt emission mechanism? Several models are currently proposed, which are in some cases mutually exclusive and are highly dependent on the properties of the jet and the central engine's dynamics. - What is the central engine of a LGRB? To date there are two competing scenarios, involving either an accreting black hole (collapsar) or a highly magnetized proto-neutron star (millisecond magnetar). Combining state-of-the-art core-collapse supernova models with high-performance GPU-accelerated relativistic jet simulations, the BlackJET project will provide a unified picture of LGRBs by consistently modeling all stages from the start of the stellar collapse to the observed electromagnetic emission. This holistic approach will unveil the intimate connection between stellar progenitor, accreting central engine, and relativistic jet, ultimately disclosing the observational signatures that a realistic LGRB progenitor should produce. By bridging the gap between stellar evolution and GRB astronomy we will be able to effectively address the fundamental questions about the nature of LGRBs.
