Abstract In this talk, I will employ an ADM deparametrization strategy to discuss the radial canonical formalism for asymptotically AdS gravity in three dimensions. It leads to the identification of a radial 'time' before quantization, namely the volume …

Abstract The strong mutual repulsion of electrons is responsible for some of the most interesting phenomena in contemporary condensed matter physics, where examples range from unconventional high-temperature superconductivity, over quantum criticality to …

Abstract This lecture will explore the molecular basis of the dialogue between the nervous and immune systems, highlighting cytokines, stress mediators and shared receptors. It will also show how the major sensory systems (notably the vagal system, …

Project under the direction of  : Philippe Aghion, chair Economics of Institutions, Innovation and Growth and Pierre-Michel Menger, chair Sociology of Creative Work . Abstract Climate change is one of the most pressing challenges facing the world today. …

Abstract In France, as long as the procedure is performed by a doctor or midwife, the law allows all women to have an abortion within the fourteen-week time limit   -   - that's voluntary interruption of pregnancy. Recourse to abortion is particularly …

Documents and media Download support Abstract Abortion is a major cause of mortality and morbidity in countries where it is prohibited or severely restricted. Although abortion no longer poses health problems in France, some women still have difficulty …

Abstract Biological invasions are one of the main threats to biodiversity. Numerous studies have demonstrated the harmful effects of biological invasions in species extinctions, particularly among island species. However, biodiversity is not only limited …

Abstract This lecture, based on the work of our research group, will address some specific aspects of biological invasions worldwide, in particular how to predict what future invasive alien species will be, and in which regions of the world they will …

Abstract I will discuss the canonical quantization of quantum cosmology on toroidal universes. The wavefunctions are automorphic forms, and the Wheeler-DeWitt equation reduces to a dynamical equation on moduli space, so quantum cosmology can be viewed as …

Abstract Quantum gases in optical cavities have shown many exciting phenomena such as the self-organization into superradiant phases. Additionally many complex phases have been predicted to be realizable in these systems reaching from topologically …

Abstract Traditionally, actors were hired to do jobs that condemned them to playing the same range of characters throughout their careers. It was in the 1980s, with Antoine Vitez in particular, that this practice began to crumble, giving way to roles and …

Abstract This first lecture will trace the evolution of knowledge on the relationship between the immune and nervous systems. From an initial vision of two isolated systems to the recognition of their dynamic interconnections, it will present the major …
