A cell membrane model that reproduces cortical flow-driven cell migration and collective movement
Katsuhiko Sato
Many fundamental biological processes are dependent on cellular migration. Although the mechanical mechanisms of single-cell migration are relatively well understood, those underly…
Polarized interfacial tension induces collective migration of cells, as a cluster, in a three-dimensional tissue
Satoru Okuda, Katsuhiko Sato
Cells collectively migrate as a cluster in three-dimensional (3D) tissues, such as in embryogenesis and cancer invasion. Here, numerical simulations using a 3D vertex model show th…
Deformation of Equilibrium Shape of a Vesicle Induced by Injected Flexible Polymers
Yutaka Oya, Katsuhiko Sato, Toshihiro Kawakatsu
Using field theoretic approach, we study equilibrium shape deformation of a vesicle induced by the presence of enclosed flexible polymers, which is a simple model of drug delivery…
Thermodynamic potential of a mechanical constitutive model for two-phase band flow
Katsuhiko Sato, Xue-Feng Yuan, Toshihiro Kawakatsu
Starting from a simple mechanical constitutive model (the non-local diffusive Johnson-Segalman model; DJS model), we provide a rigorous theoretical explanation as to why a unique v…
Modeling of the Peeling Process of Pressure-sensitive Adhesive Tapes with the Combination of Maxwell Elements
Katsuhiko Sato, Akihiko Toda
A simple model for the peeling process of pressure-sensitive adhesive tape is presented. The model consists of linear springs and dashpots and can be solved analytically. Based on…
Irreversibility resulting from contact with a heat bath caused by the finiteness of the system
K. Sato, K. Sekimoto, T. Hondou +1
When a small dynamical system that is initially in contact with a heat bath is detached from this heat bath and then caused to undergo a quasi-static adiabatic processes, the stati…
