Abstract A thought, in the sense of Descartes and the Cartesians, is a content of consciousness, whatever it may be. Some contents of consciousness are " representative " and have an object to which they relate. Among these, we distinguish between those …

Abstract The immense diversity of floral characteristics (flower shape, size and color, floral odors) is commonly explained by the shared evolutionary history between plants and pollinators. The many species of pollinator are thought to have played a …

Abstract In the history of life, the first interactions between plants and pollinators were almost concomitant with the appearance of flowering plants, or even preceded it. Through natural selection mechanisms, they led to the evolution of traits that …

Abstract In the past few years, there has been considerable activity around a set of quantum bounds on transport coefficients (viscosity, conductivity) and chaos (Lyapunov exponents), relevant at low temperatures. The interest comes from the fact that …

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 by Joel Friedman, and several …

Abstract Political debates offer citizens a unique opportunity to appreciate the position of political representatives on the most controversial issues of the day. In view of the active expression of the various players in political life, these debates …

Abstract Hyperbolic systems in dimension 1 of space play a crucial role in various real-life domains such as navigable rivers, irrigation canals, heat exchangers, chemical reactors, gas pipelines, road traffic, chromatography, and many others. This talk …

Abstract People seem to have an early understanding of the world around them, and the other people in it. Before children can reliably say "ball", "wall", or "Saul", they expect balls not to go through walls, and for Saul to go right for a ball (if …

The Origins of Geometric Symbols since Prehistory: A Language of Thought? Abstract In the Lascaux cave, just below the magnificent drawing of a large deer, is the simple but unmistakable outline of a rectangle. All over the world, since prehistoric times, …

Abstract The twenty-two administrative metropolises and the agglomerations surrounding major urban centers share a number of specific features in terms of both vulnerability and capacity for action. The density of their populations, facilities and …

Keynote conference. Abstract The evolution of cities in response to global warming, whether in terms of transport logistics, decarbonization of the economy or adaptation to new climatic conditions, will lead to an evolution of materials in the direction …

Abstract The purpose of this presentation is to analyze the current and future role of the hospital in the city, and more generally in the …

Abstract Cities of the future will need to monitor pathogen mutations in animal and human populations to anticipate species crossings causing pandemics. They will need to prepare these populations with sentinels to detect early warning signals, and with …

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. …
