Searching for a source without gradients: how good is infotaxis and how to beat it
Aurore Loisy, Christophe Eloy
Infotaxis is a popular search algorithm designed to track a source of odor in a turbulent environment using information provided by odor detections. To exemplify its capabilities,…
Seismic response of cylinder assemblies in axial flow
Roberto Capanna, Guillaume Ricciardi, Emmanuelle Sarrouy +1
Earthquakes are a great challenge for the safety of nuclear reactors. To address this challenge, we need to better understand how the reactor core responds to seismic forcing. The…
Surfing on turbulence: a strategy for planktonic navigation
Rémi Monthiller, Aurore Loisy, Mimi A. R. Koehl +2
In marine plankton, many swimming species can perceive their environment with flow sensors. Can they use this flow information to travel faster in turbulence? To address this quest…
How memory architecture affects learning in a simple POMDP: the two-hypothesis testing problem
Mario Geiger, Christophe Eloy, Matthieu Wyart
Reinforcement learning is generally difficult for partially observable Markov decision processes (POMDPs), which occurs when the agent's observation is partial or noisy. To seek go…
Rebound and scattering of motile Chlamydomonas algae in confined chambers
Albane Théry, Yuxuan Wang, Mariia Dvoriashyna +3
Motivated by recent experiments demonstrating that motile algae get trapped in draining foams, we study the trajectories of microorganisms confined in model foam channels (section…
Zonal flow in a resonant precessing cylinder
Donglai Gao, Patrice Meunier, Stéphane Le Dizès +1
A cylinder undergoes precession when it rotates around its axis and this axis itself rotates around another direction. In a precessing cylinder full of fluid, a steady and axisymme…
