This task is made all the more difficult by the fact that the physical modeling of these … 1 Mar 2023 11:15 to 12:30 Event Stéphane Mallat Maximum entropy distributions Lecture Abstract Jaynes maximum entropy models link statistical physics to data modeling. A probability distribution is specified by moments (expectations of generating functions) maximizing its entropy, which amounts to making explicit the fact that we have no … 1 Mar 2023 09:30 to 11:00 Event Patrice Simon Ion transport in confined spaces : application to electrochemical energy storage Seminar Abstract Electrochemical energy storage (batteries, supercapacitors), driven mainly by the development of electric mobility, has now become a major societal and economic challenge (reducing dependence on fossil fuels and combating CO2 emissions). … 1 Mar 2023 15:30 to 17:00 Event Lydéric Bocquet Ion transport, from molecular sieving to Coulomb blocking Lecture The movement of ions across nanopores, or nanoporous membranes, is the elementary process at the heart of most transport issues in biological membranes, or in separation, desalination or osmotic energy technologies.

It's a given : we're going to have to face up to the climate change we've caused or exacerbated. But beyond the imperatives of adaptation and transition, we need to ask ourselves … 17 Nov 2021 Event Bruno David At the dawn of the sixth extinction Seminar Abstract Everyone is familiar with the term " biodiversity ". But what does this apparently simple term actually mean? We hear it over and over again: " biodiversity is in crisis ". Are we on the verge of a sixth extinction, with ourselves as the cause ? … 27 Feb 2023 11:00 to 12:00 Event Virginie Courtier-Orgogozo Functionalization and hierarchization of living organisms Lecture Humans occupy a place like any other in the tree of life.

These methods are most often based on the minimization of a function, for which the minimizers are assumed to be the solutions of the synthesis problem. In this … 22 Feb 2023 11:15 to 12:30 Event Stéphane Mallat Entropy increase and macrocanonical assemblies Lecture Abstract The entropy rate of a Markov chain is calculated as a function of its transition matrix.
