How cells surf the waves? Curvotaxis directs migration trough cell-scale natural landscapes

Laurent Pieuchot, Maxime Vassaux, Julie Marteau, Thomas Cloatre, Tatiana Petithory, Isabelle Brigaud, Pierre-François Chauvy, Arnaud Ponche, Jean-Louis Milan, Pablo Rougerie, Maxence Bigerelle, Karine Anselme

Cells have evolved specific sensing mechanisms to recognize and integrate a diverse set of environmental cues. It is now well established that cells can detect sub-cellular topographical features, and these physical cues are sufficient to direct cell migration and trigger stem cell commitment to...

On the vortex dynamics of shear-driven deep cavity flows with asymmetrical walls

Denis Cornu, Laurent Keirsbulck, Franck Kerhervé, Fethi Aloui, Marc Lippert

The influence of the length-to-depth aspect ratio and of wall asymmetry on the main vortical flow structures evolving in rectangular two-dimensional deep cavities is studied experimentally using wall-pressure and particle image velocimetry (PIV) measurements. Wall-pressure and cavity flow..., En utilisant des mesures de la pression du mur et de PIV, nous étudions expérimentalement l’influence du rapport de forme longueur versus profondeur et de l’asymétrie du mur sur la structure d’écoulement tourbillonnant principal évoluant dans des cavités profondes à deux dimensions rectangulaires....

Contribution à la modélisation biofidèle de l’être humain par la prise en compte des interactions fluide-structure, Toward a more biofidelic modelling of the human body involving fluid-structure interactions

Benoît Fontenier

Ces travaux visent à améliorer la biofidélité des modèles virtuels de l’être Humain. Les statistiques montrent que la tête humaine est fréquemment sujette à des traumatismes cérébraux, des lésions et autres blessures. Une attention particulière sera donc donnée à la modélisation de la tête. Afin de..., The purpose of this work is to improve the biofidelity of the human body models. The work is focused on the human head as it is one of the most injured part. In order to improve the traumatic brain injury onset and mechanism, the biofidelity of the head models has to be increased, thus, the fluids...

Discrete sensors distribution for accurate plantar pressure analyses

Laetitia Claverie, Anne Ille, Pierre Moretto

The aim of this study was to determine the distribution of discrete sensors under the footprint for accurate plantar pressure analyses. For this purpose, two different sensor layouts have been tested and compared, to determine which was the most accurate to monitor plantar pressure with wireless...
