Mechanical stress induced by the polymerisation of an active gel near a surface
Kristiana Mihali, Dennis Wörthmüller, Pierre Sens
Actin flow in the cortical cytoskeleton underneath the cell membrane generates mechanical stresses that shape the cell surface. We study this mechanism using a hydrodynamic model o…

Microscopic origin of macroscopic contractility in actin-myosin active gel models
Artur Alexandre, Nicola Dietler, Simone Cicolini +3
Actin filaments, crosslinkers and myosin molecular motors form contractile networks. For instance, the cell cortex is a thin network below the cell membrane ; contraction of the ce…

IRENE: a fluId layeR finitE-elemeNt softwarE
Dennis Wörthmüller, Gaetano Ferraro, Pierre Sens +1
We present a finite-element software library, IRENE, which allows to solve numerically the dynamics of a viscous fluid layer embedded in three-dimensional space. Unlike finite-elem…
