#Actomyosin #Mechanical #Myosin

Our article on the #mechanics of "active" entropic biopolymer networks [possibly including #actomyosin, this is debated experimentally] is now published in J Elas.

Compared to enthalpic models, we're able to go right from the #thermodynamics of an unbiased #molecularMotor activity (in the spirit of the model by #JacquesProst for #myosin) at the molecular scale to a network-scale model in a closed form.

And we derive a method for solving quite easily the (usually tough) #viscoelastic #liquid model that we obtain, using #deformationGradientDecomposition.

Our #preprint where we derive an #activeGel #model with entropic elasticity of the #microstructure from the thermodynamic constraints on the dynamics of #myosin molecular motors is now updated!

Hopefully more readable, and with the example of a #cyst like contractile sphere.
