Fluid migration strongly influences gas hydrate occurrences, increasing concentrations in proportion to gas supply. An upward flow of gas-rich fluids is also central to models proposed to account for the formation of venting features within the gas hydrate stability zone (GHSZ), and for the presence or absence at its based of bottom simulating refl...
Let $p$ be an odd prime number. We propose an algorithm for computing rational representations of isogenies between Jacobians of hyperelliptic curves via-adic differential equations with a sharp analysis of the loss of precision. Consequently, after having possibly lifted the problem in the $p$-adics, we derive fast algorithms for computing explici...

Objectif : La relative brutalité du rugby fauteuil contraste avec la fragilité qui pourrait être perçue chez des personnes en situation de handicap. Le corps, soumis à des limitations fonctionnelles au quotidien, se trouve en action. Le but de ce travail est alors d’explorer ce que modifie le rugby fauteuil sur le rapport au corps des joueurs.Métho...

This article reports investigations on the anoxic corrosion process impacting a carbon steel/ultrapure deaerated water system when it is exposed to gamma radiation (50 Gy h$^{-1}$ ), and on the associated molecular hydrogen gas generation. On the one hand, a dynamic semi-open experimental setup allowing to distinguish between the H$_2$ production r...
