Directional Cluster Migration Driven by Escape-Rate Asymmetry in Multi-Compartment Granular Systems
Kai Kono, Hiroyuki Ebata, Shio Inagaki
Granular materials are inherently out-of-equilibrium systems due to energy dissipation through inelastic collisions and friction. When driven by mechanical agitation such as vibrat…

Depth and slip ratio dependencies of friction for a sphere rolling on a granular slope
Takeshi Fukumoto, Hiroyuki Ebata, Ishan Sharma +1
We experimentally investigate the dynamics of a sphere rolling down a granular slope by varying the initial velocity, slope angle, and sphere density. The results show that the sph…

Why epithelial cells collectively move against a traveling signal wave
Tatsuya Fukuyama, Hiroyuki Ebata, Akihisa Yamamoto +6
The response of cell populations to external stimuli plays a central role in biological mechanical processes such as epithelial wound healing and developmental morphogenesis. Wave-…
