Viscous vertex model for active epithelial tissues
Shao-Zhen Lin, Sham Tlili, Jean-François Rupprecht
We present a rotationally invariant viscous vertex model that accounts for both cortical and bulk dissipation of cells. The vanishing substrate-friction limit is enforced via Lagra…

Noninvasive rheological inference from stable flows in confined tissues
Marc Karnat, Gautham Hari Narayana, Sudheer Kumar Peneti +8
Quantifying the in-plane rheology of epithelial monolayers remains challenging due to the difficulty of imposing controlled shear. We introduce a self-driven, rheometer-like assay…

Inferring viscoplastic models from velocity fields: a physics-informed neural network approach
Martin Lardy, Sham Tlili, Simon Gsell
Fluid-like materials are ubiquitous, spanning from living biological tissues to geological formations, and across scales ranging from micrometers to kilometers. Inferring their rhe…
