Solid-to-solid transition in dense assemblies of elongated cells

Shao-Zhen Lin, Jean-François Rupprecht

Cell shapes in confluent tissues range from nearly isotropic epithelial morphologies to highly elongated endothelial ones. In standard vertex models, tissue rigidity is controlled…

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…

Spontaneous flows in active smectics with dislocations

Shao-Zhen Lin, Frank Jülicher, Jacques Prost +1

We construct a hydrodynamic theory of active smectics A in two-dimensional space, including the creation/annihilation and motility of dislocations with Burgers' number . We d…

The escape problem for mortal walkers

D. S. Grebenkov, J. -F. Rupprecht

We introduce and investigate the escape problem for random walkers that may eventually die, decay, bleach, or lose activity during their diffusion towards an escape or reactive reg…

Exact mean exit time for surface-mediated diffusion

J. -F. Rupprecht, O. Bénichou, D. S. Grebenkov +1

We present an exact expression for the mean exit time through the cap of a confining sphere for particles alternating phases of surface and of bulk diffusion. The present approach…
