Abstract First appearing in the theoretical field, the black hole is now part of the standard astrophysical bestiary. After introducing the concept of the black hole within the framework of the relativistic theory of gravitation - general relativity - we …

Abstract Stars with masses greater than 8 solar masses have a very short life on the main sequence, and then burn helium, followed by carbon, oxygen, etc., until they have a core of iron and silicon. Fusion continues in shells, until the core implodes and …

Abstract What if we built the headquarters of the UN at the center of the earth, equidistant from all states, to make it the very place of the universal ? This seemingly absurd proposal comes not from a science-fiction novel, but from Voltaire's 1761 …

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 Flowering plants appeared on the planet over 100 million years ago, and have enjoyed remarkable evolutionary success : they now represent the majority of the living mass on the planet, are at the base of most terrestrial food chains, including …

Abstract Ruelle resonances are characteristics of a dynamical system that describe the fine asymptotics of large-time correlations. It is now well known that this notion is well defined for uniformly hyperbolic smooth systems on compact varieties. In this …

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 …

Abstract Recently, Dang and Rivière proved a remarkable identity, which expresses the 0-value of the Poincaré series of any surface of negative curvature as a function of the Euler characteristic. Thus, a Dirichlet series defined from the lengths of …

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 Text generation can target different types of languages and take different types of knowledge as input. In this presentation, I will show how neural language models can be adapted to generate text from semantic representation graphs, knowledge …

Abstract Consider a control problem consisting in finding a trajectory connecting an initial point x to a target point y , with the system moving only in certain admissible directions. It is assumed that the corresponding vector fields satisfy the …

Abstract Some further downstream tasks : named entity recognition ; syntactic analysis ; sentence classification : classical approaches, sentence embeddings  ; text …
