Mixing and unmixing induced by active camphor particles

Article dans Phys. Rev. Fluids (2021)

Mixing and unmixing induced by active camphor particles

Clément Gouiller, Florence Raynal, Laurent Maquet, Mickaël Bourgoin, Cécile Cottin-Bizonne, Romain Volk & Christophe Ybert

Small colloidal floaters are poured at the air-water interface of a tank stirred by many camphor swimmers. The system rapidly reaches a statistically stationary state resulting in the competition (...)

A phenomenological and multiscale modeling of arterial growth and remodeling under endofibrosis

Article dans Comput. Methods Biomech. Biomed. Eng. (2020)

A phenomenological and multiscale modeling of arterial growth and remodeling under endofibrosis

Jérôme Jansen, Xavier Escriva, Fabien Godeferd & Patrick Feugier

High level endurance sports, like biking, may lead to a vascular pathology called endofibrosis. Its symptoms are an arterial wall thickening and a reduction of the artery lumen calibre. Cyclists (...)
