Functionality of disorder in muscle mechanics
Hudson Borja da Rocha, Lev Truskinovsky
A salient feature of skeletal muscles is their ability to take up an applied slack in a microsecond timescale. Behind this remarkably fast adaptation is a collective folding in a b…
Statistical mechanics of the Huxley-Simmons model
M Caruel, L Truskinovsky
The chemomechanical model of Huxley and Simmons (HS) [A. F. Huxley and R. M. Simmons, Nature 233, 533 (1971)] provides a paradigmatic description of mechanically induced collective…
Paramagnetic response of muscle-type systems
Matthieu Caruel, Lev Truskinovsky
We provide a prototypical description of mechanically-induced collective conformational change (folding), relevant in a variety of biological contexts from muscle contraction to ha…
Pseudo energy wells in active systems
Raman Sheshka, Pierre Recho, Lev Truskinovsky
Active stabilization in systems with zero or negative stiffness is an essential element of a wide variety of biological processes. We study a prototypical example of this phenomeno…
Mechanics of motility initiation and motility arrest in crawling cells
Pierre Recho, Thibaut Putelat, Lev Truskinovsky
Motility initiation in crawling cells requires transformation of a symmetric state into a polarized state. In contrast, motility arrest is associated with re-symmetrization of the…
Cooperative folding of muscle myosins: I. Mechanical model
Matthieu Caruel, Jean-Marc Allain, Lev Truskinovsky
Mechanically induced folding of passive cross-linkers is a fundamental biological phenomenon. A typical example is a conformational change in myosin II responsible for the power-st…
