Keynote conference. Abstract Cities are home to a high proportion of the population ; temperature, air pollution and noise levels are generally higher there than elsewhere ; and they are more vulnerable to rising sea levels and flood risks. As a result, …

Abstract To meet future urban challenges, many cities have embarked on a process of " renaturation ", through revegetation programs and actions to increase biodiversity. These actions have many positive impacts on the health and well-being of residents. …

Abstract All-solid-state batteries, touted for their enhanced safety and superior energy density, are emerging as the preferred solution for the future, attracting considerable interest in the electric vehicle sector. Currently, this technology is the …

Abstract Philippe Clergeau will present the concept of regenerative urbanism, after recalling the definitions of biodiversity and ecosystems, which are essential to a liveable, sustainable city. Nature-based solutions already permeate architecture, but we …

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 …

Abstract New York, the city of exile for the Surrealists and ethnologist Claude Lévi-Strauss, is the capital of the modern, but also the refuge of the archaic. " Ali Baba's cave ", it provides backdoor exits and an escape from the time 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 Conversational agents, chatbots and large language models   : from Eliza to ChatGPT and ChatLLAMA. How have very large conversational models been trained ? What are their limits, ethical issues, uses and …

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 …
