Pattern formation and the mechanics of a motor-driven filamentous system confined by rigid membranes
Mitsusuke Tarama, Tatsuo Shibata
Pattern formation and the mechanics of a mixture of actin filaments and myosin motors that is confined by a rigid membrane is investigated. By using a coarse-grained molecular dyna…
Mechanochemical subcellular-element model of crawling cells
Mitsusuke Tarama, Kenji Mori, Ryoichi Yamamoto
Constructing physical models of living cells and tissues is an extremely challenging task because of the high complexities of both intra- and intercellular processes. In addition,…
Mechanics of cell crawling by means of force-free cyclic motion
Mitsusuke Tarama, Ryoichi Yamamoto
The mechanics of crawling cells on a substrate is investigated by using a minimal model that satisfies the force-free condition. A cell is described by two subcellular elements con…
Dynamics of Deformable Active Particles under External Flow Field
Mitsusuke Tarama
In most practical situations, active particles are affected by their environment, for example, by a chemical concentration gradient, light intensity, gravity, or confinement. In pa…
Swinging Motion of Active Deformable Particles in Poiseuille Flow
Mitsusuke Tarama
Dynamics of active deformable particles in an external Poiseuille flow is investigated. In order to make the analysis general, we employ time-evolution equations derived from symme…
Tunable dynamic response of magnetic gels: impact of structural properties and magnetic fields
Mitsusuke Tarama, Peet Cremer, Dmitry Y. Borin +3
Ferrogels and magnetic elastomers feature mechanical properties that can be reversibly tuned from outside through magnetic fields. Here we concentrate on the question how their dyn…
A deformable microswimmer in a swirl: capturing and scattering dynamics
Mitsusuke Tarama, Andreas M. Menzel, Hartmut Löwen
Inspired by the classical Kepler and Rutherford problem, we investigate an analogous set-up in the context of active microswimmers: the behavior of a deformable microswimmer in a s…
Individual and collective dynamics of self-propelled soft particles
M. Tarama, Y. Itino, A. M. Menzel +1
Deformable self-propelled particles provide us with one of the most important nonlinear dissipative systems, which are related, for example, to the motion of microorganisms. It is…
Dynamics of a deformable active particle under shear flow
Mitsusuke Tarama, Andreas M. Menzel, Borge ten Hagen +3
The motion of a deformable active particle in linear shear flow is explored theoretically. Based on symmetry considerations, in two spatial dimensions, we propose coupled nonlinear…
Spinning motion of a deformable self-propelled particle in two dimensions
Mitsusuke Tarama, Takao Ohta
We investigate the dynamics of a single deformable self-propelled particle which undergoes a spinning motion in a two-dimensional space. Equations of motion are derived from the sy…
Dynamics of a deformable self-propelled particle under external forcing
Mitsusuke Tarama, Takao Ohta
We investigate dynamics of a self-propelled deformable particle under external field in two dimensions based on the model equations for the center of mass and a tensor variable cha…
