Transport phenomena in spatially periodic systems far from thermal equilibrium are
considered. The main emphasis is put on directed transport in so-called Brownian motors …

A molecular motor is made of either a single macromolecule or a macromolecular complex.
Just like their macroscopic counterparts, molecular motors “transduce” input energy into …

Unlike equilibrium statistical mechanics, with its well-established foundations, a similar
widely accepted framework for non-equilibrium statistical mechanics (NESM) remains …

Myosin II is a molecular motor that converts chemical energy derived from ATP hydrolysis
into mechanical work. Myosin II isoforms are responsible for muscle contraction and a range …

Transport by processive molecular motors plays an important role in many cell biological
phenomena. In many cases, motors work together to transport cargos in the cell, so it is …

In muscle, force emerges from myosin binding with actin (forming a cross-bridge). This
actomyosin binding depends upon myofilament geometry, kinetics of thin-filament Ca2+ …

Muscles produce force and power by utilizing chemical energy through ATP hydrolysis.
During concentric contractions (shortening), muscles generate less force compared to …

The collective dynamics of N interacting processive molecular motors are considered
theoretically when an external force is applied to the leading motor. We show, using a …

The cellular cytoskeleton is well studied in terms of its biological and physical properties,
making it an attractive subject for systems approaches. Here, we describe the experimental …

We investigate the isometric transient response of muscle using a quantitative stochastic
model of the actomyosin cycle based on the swinging lever-arm hypothesis. We first …
