Fluctuations can induce local nematic order and extensile stress in monolayers of motile cells

Posted by klaurent UCSB

Kavli Affiliate: Boris I. Shraiman | Summary:Recent experiments in various cell types have shown that two-dimensional tissues often display local nematic order, with evidence of extensile stresses manifest in the dynamics of topological defects. Using a mesoscopic model where tissue flow is generated by fluctuating traction forces coupled to the nematic order parameter, we show […]

Kavli Affiliate: Paul L. Schechter | First 5 Authors: Anowar J. Shajib, Eden Molina, Adriano Agnello, Peter R. Williams, Simon Birrer | Summary: We report upon three years of follow-up and confirmation of doubly imaged quasar lenses through imaging campaigns from 2016-2018 with the Near-Infrared Camera2 (NIRC2) on the W. M. Keck Observatory. A sample […]
