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…
Amoeboid movement utilizes the shape coupled bifurcation of an active droplet to boost ballistic motion
H. Ebata, Y. Nishigami, H. Fujiwara +2
One of the essential functions of living organisms is spontaneous migration through the deformation of their body, such as crawling, swimming, and walking. Depending on the size of…
Convection of mono-disperse particles in a highly filled rotating cylinder
Shoichi Yoneta, Hiroyuki Ebata, Shio Inagaki
We investigate the occurrence of spontaneous convection in a coaxial cylinder highly filled with mono-disperse spheres. To analyze the flow field non-invasively, initial pulses con…
Segregation patterns in rotating cylinders determined by the size difference, density ratio, and cylinder diameter
Kurumi Kondo, Hiroyuki Ebata, Shio Inagaki
Granular materials often segregate under mechanical agitation, which differs from the expectation of mixing. It is well known that a bidisperse mixture of granular materials in a p…
Self-replicating segregation patterns in horizontally vibrated binary mixture of granules
Hiroyuki Ebata, Shio Inagaki
When granular mixtures of different sizes are fluidized, each species spontaneously separates and condenses to form patterns. Although granular segregation has been extensively stu…
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-…
