Vesicles with internal active filaments: self-organized propulsion controls shape, motility, and dynamical response

Particle with internal dynamical asymmetry : chaotic self - propulsion and turning

We consider model of a complex particle that consists of a rigid shell and a nucleus with spatial asymmetric interaction. The particle's dynamics with the nucleus driven by a periodic excitation is considered. It is shown that unidirectional self-propulsed particle motion arises in the absence of spatial and temporary asymmetry of external potentials and influences. Transport modes are the gene...

Cytoplasmic filaments: their role in motility and cell shape

M.oving cells are fascinating to watch. Today, 300 years after cells and their movements were first observed with the primitive microscopes of van Leeunwenhoek, cell biologists are beginning to understand how cells move. New fluorescence and electron microscopic techniques are now being used in eye research to study cell movements which occur in corneal wound healing, phagocytosis by the retina...

Nonuniform self-organized dynamical states in superconductors with periodic pinning.

We consider magnetic flux moving in superconductors with periodic pinning arrays. We show that sample heating by moving vortices produces negative differential resistivity (NDR) of both N and S type (i.e., N- and S-shaped) in the voltage-current characteristic (VI curve). The uniform flux flow state is unstable in the NDR region of the VI curve. Domain structures appear during the NDR part of t...
