Many cellular processes require molecular motors to produce motion and forces. Single
molecule experiments have led to a precise description of how a motor works. Under most …

Raphid diatoms are one of the few eukaryotes capable of gliding motility, which is
remarkably fast and allows for quasi-instantaneous directional reversals. Besides other …

Forces in the actin cytoskeleton are generated by small groups of nonprocessive myosin II
motors for which stochastic effects are highly relevant. Using a cross-bridge model with the …

Non-processive molecular motors have to work together in ensembles in order to generate
appreciable levels of force or movement. In skeletal muscle, for example, hundreds of …

We present a detailed analysis of the dynamical instabilities appearing in two kinetic
theories for the collective behavior of molecular motors: the rigid two-state model and the …

Active cellular transport along microtubules is driven by the concerted operation of
molecular motors. This often leads to complex dynamic behaviors such as stop-and-go or …

Fluid-resistance limited transport of vesicles through narrow constrictions is a recurring
theme in many biological and engineering applications. Inspired by the motor-driven …

We present a detailed calculation that enables us to estimate the reversal time of a
molecular motor assembly that displays bidirectional motion in the limit of weak noise. We …

Bidirectional motion is an example of collective behavior of molecular motors. It occurs at
finite noise level in a nonequilibrium system. We consider this problem as a first exit …

We analyze theoretically the problem of cargo transport along microtubules by motors of two
species with opposite polarities. We consider two different one-dimensional models …
