Abstract Rivers have long been the focus of attention in international law, as natural boundaries or as routes for navigation and trade between states. Gradually, other uses emerged, such as fishing, energy production and agricultural and industrial uses. …

How can we encode a mental representation using a neural vector in a high-dimensional space ? The lecture will take the example of visual recognition : every object, every face we recognize is encoded by the activity of a population of neurons in the …

Abstract Freshwater, the source of life, is a natural resource with a unique character. It is a constant quantity with changing states. Access to and management of this resource must be equitable, both nationally and internationally. International law …

Abstract Galaxy formation is a two-step process . The gravitational instability of primordial density fluctuations forms dark matter halos. The collapse of gas into matter halos forms luminous galaxies. Semi-analytical modeling treats these two steps …

Abstract Galaxies begin to glow when ordinary matter collapses into pre-existing dark matter halos, forming stars. Initially, the universal fraction of ordinary matter is 17   %, but due to feedback phenomena from star formation (supernovae, stellar …

This lecture has been rescheduled for Wednesday, January 25, from 2 to 4 p.m. Exceptionally, Prof. Esther Duflo will give her last two lectures on Thursday January 26 and Friday January 27, at 2 pm (Marguerite de Navarre …

Abstract Much scholarly attention has focused on the military and defensive character of Rome's frontier provinces, with trade recognized as a significant element only in rare or exceptional cases (India, Silk Road). Based on a study focusing on the …

Abstract I will review the role of the quantum unique ergodicity (QUE) notion of delocalization, in the context of random matrices. QUE can be proved by dynamic or combinatorial methods, and implies that the local eigenvalues statistics exhibit the …

In his Supplément au Voyage de Bougainville , Diderot evokes the presence of Ahutoru, the Tahitian brought back by Bougainville from his voyage around the world (1766-1769), but denies him any ability to understand what is happening to him, to make sense …

After outlining the essential results of spin glass theory , the archetype of disordered systems in statistical physics , I'll show how these general concepts apply to systems as diverse as random proteins and heteropolymers , neural networks and …
