Collective Cell Movement in Cell-Scale Tension Gradient on Tissue Interface
Katsuyoshi Matsushita, Hidenori Hashimura, Hidekazu Kuwayama +1
In this paper, we examine the emergence of cell flow induced by a tension gradient on a tissue interface as in the case of the Marangoni flow on liquid interface. We consider the m…
Cell Motion Alignment as Polarity Memory Effect
Katsuyoshi Matsushita, Kazuya Horibe, Naoya Kamamoto +1
The clarification of the motion alignment mechanism in collective cell migration is an important issue commonly in physics and biology. In analogy with the self-propelled disk, the…
Curved surface geometry-induced topological change of an excitable planar wave
Kazuya Horibe, Ken-ichi Hironaka, Katsuyoshi Matsushita +1
On the curved surfaces of living and nonliving materials, planar excitable waves frequently exhibit directional change and subsequently undergo a topological change; that is, a ser…
Emergence of collective propulsion through cell-cell adhesion
Katsuyoshi Matsushita
The mechanisms driving the collective movement of cells remain poorly understood. To contribute toward resolving this mystery, a model was formulated to theoretically explore the p…
Penetration of a magnetic wall into thin ferromagnetic electrodes of a nano-contact spin valve
Munetaka Sasaki, Susumu Tanaka, Yousuke Norizuki +3
We theoretically analyzed a magnetic wall confined in a nano-contact spin valve paying special attention to the penetration of the magnetic wall into thin ferromagnetic electrodes.…
Dipolar field effect on microwave oscillation in a domain wall spin-valve
Katsuyoshi Matsushita, Jun Sato, Hiroshi Imamura
We examined dipolar field effects on the microwave generation in the domain wall spin-valve by solving simultaneously the Landau-Lifshitz-Gilbert and Zhang-Levy-Fert diffusion equa…
