Curvotaxis directs cell migration through cell-scale curvature landscapes

Laurent Pieuchot, Julie Marteau, Alain Guignandon, Thomas dos Santos, Isabelle Brigaud, Pierre-Francois Chauvy, Thomas Cloatre, Arnaud Ponche, Tatiana Petithory, Pablo Rougerie, Maxime Vassaux, Jean-Louis Milan, Nayana Tusamda Wakhloo, Arnaud Spangenberg, Maxence Bigerelle, Karine Anselme

Cells have evolved multiple mechanisms to apprehend and adapt finely to their environment. Here we report a new cellular ability, which we term ``curvotaxis'' that enables the cells to respond to cell-scale curvature variations, a ubiquitous trait of cellular biotopes. We develop ultra-...

On the modeling of a visco-hyperelastic polymer gel under blunt ballistic impacts

Anthony Bracq, Grégory Haugou, Benjamin Bourel, Christophe Maréchal, Franck Lauro, Sébastien Roth, Olivier Mauzac

In this paper, the modeling of a polymer gel used as target medium in blunt ballistic experiments is presented. A new visco-hyperelastic law based on the Mooney–Rivlin model is proposed and implemented in a numerical simulation software. The material model identification relies on mechanical...
