Image generated by artificial intelligence. Overview This conference will build on the course material by bringing together researchers who explore the microbial world at various scales: molecular, cellular, community, ecosystem, and planetary. Its goal …

Le recours de plus en plus fréquent à la gestion de crise pour gouverner des situations marquées par l’incertitude et la complexité conduisent souvent à une centralisation des décisions, parfois accompagnée d’une réduction des libertés publiques et d’un …

Abstract The decomposition of ocean dynamics into a superposition of waves is based on a linear approximation of the equations of fluid mechanics, which, in particular, neglects convective effects. For small-amplitude motions, these couplings can be …

Documents and Media Download the support material Abstract We consider the problem of approximating a subset M of a Hilbert space X by a low-dimensional manifold M n . A large class of nonlinear methods can be described by a decoder D : IR n → X whose …

Abstract Inertial and internal waves caused by ocean rotation and stratification are governed by continuous-spectrum propagators, and their couplings—even weak ones—cannot be analyzed using envelope equation techniques. The emergence of energy fluxes in …

Abstract Understanding how to optimally approximate general compact sets using finite-dimensional spaces is of central interest for designing efficient numerical methods in forward simulation or inverse problems. The concept of n-width, introduced in 1936 …

Abstract Resonance phenomena can lead to large-amplitude fluctuations that can no longer be analyzed perturbatively, yet play a fundamental role either because of their impact (extreme events) or because they profoundly alter the nature of the physical …
