The importance of being discrete -- An agent-based model for active nematics and more
Mathieu Dedenon, Carles Blanch-Mercader, Karsten Kruse +1
We propose an agent-based model of active flexible rods. Inspired by cytoskeletal flows, we introduce activity by an internal flow that contributes to the dissipative forces. The a…
Defect states in compressible active polar fluids with turnover
Ludovic Dumoulin, Carles Blanch-Mercader, Karsten Kruse
Biological active matter like the cytoskeleton or tissues are characterized by their ability to transform chemical energy into mechanical stress. In addition, it often exhibits ori…
Passive defect driven morphogenesis in nematic membranes
D. J. G. Pearce, C. Thibault, Q. Chaboche +1
Topological defects are ubiquitous on surfaces with orientational order fields. Here, we study equilibrium states generated by the feedback between geometry and nematic order on fl…
Src Kinase Slows Collective Rotation of Confined Epithelial Cell Monolayers
Nastassia Pricoupenko, Flavia Marsigliesi, Philippe Marcq +2
Collective cell migration is key during development, wound healing and metastasis and relies on coordinated cell behaviors at the group level. Src kinase is a key signalling protei…
Effective viscosity of a two dimensional passive suspension in a liquid crystal solvent
S. Dang, C. Blanch-Mercader, L. Berlyand
Suspension of particles in a fluid solvent are ubiquitous in nature, for example, water mixed with sugar or bacteria self-propelling through mucus. Particles create local flow pert…
