SUMMARY:[Biophysics seminar] Clement Zankoc: "Active Instability and Nonlinear Dynamics of Cell-Cell Junctions"
DESCRIPTION:Active cell-junction remodeling is important for tissue morphogenesis\, yet its underlying physics is not understood. We study a mechanical model that describes junctions as dynamic active force dipoles. Their instability can trigger cell intercalations by a critical collapse. Nonlinearities in tissue’s elastic response can stabilize the collapse either by a limit cycle or condensation of junction lengths at cusps of the energy landscape. Furthermore\, active junction networks undergo collective instability to drive active in-plane ordering or develop a limit cycle of collective oscillations\, which extends over regions of the energy landscape corresponding to distinct network topologies.\n\n\nThe meeting will take place online via Zoom: \nMeeting ID: 833 0750 1179 \nPasscode: bio
