Abstract Cities are particularly exposed to hydro-climatic hazards, now exacerbated by anthropogenic global warming. As both major sources of greenhouse gas emissions and vulnerable territories, cities are called upon to be drivers of mitigation and …

Abstract This paper examines the future of cities by shifting the focus to the African continent. The aim is to consider African cities as places for exploring new imaginaries and new ways of inhabiting the world. This reflection comes at a crucial time …

Abstract When it comes to building, as with energy, the new doesn't make the old disappear. The extraordinary rise of concrete between 1950 and 2000, far from eradicating other building materials, allowed them to grow : glass of course, steel, wood, but …

This lecture describes the latest advances in the emerging field of nanofluidics, the science of molecular flows, which explores fluid flow and transport at nanometric scales. This world of infinitely small fluidics is the frontier where the continuum of …

Abstract In this seminar, I will present how the study of plant-pollinator communities benefits from interaction network approaches. These approaches, which integrate both all the species making up the communities and the interactions that link these …

Abstract As with all living things, plant-pollinator interactions are not just two-by-two exchanges, but form part of the planet's living fabric, in the form of interaction networks that link almost all species to one another, from close to close, in an …

Abstract The usual semi-classical correspondence (called quantum-classical) shows that the fixed-time evolution of wave packets by a wave equation reveals the geodesic flow in the small-wavelength limit λ → 0. This geodesic flow is determined by the …

Abstract In these last two lectures, we are interested in models of random (q+1)-regular graphs with N vertices. We study the spectral hole of the adjacency matrix, in the limit where N tends to infinity. We present a result due to Joel Friedman, and …

Abstract Mutual understanding during a conversation is an extremely fast and efficient process : we can process three words per second, often more. However, this observation is not consistent with laboratory experiments showing that processing a single …

Abstract Animals behave flexibly, seamlessly generalizing knowledge between apparently different scenarios. This is the hallmark of intelligence. To do this, representations and computations in the brain must also be flexible and generalise. In this talk …
