Chiral flows can induce neck formation in viscoelastic surfaces
Eloy Merlijn de Kinkelder, Elisabeth Fischer-Friedrich, Sebastian Aland
During division in animal cells, the actomyosin cortex has been found to exhibit counter-rotating cortical flows, also known as chiral flows, along the axis of division. Furthermor…
Random traction yielding transition in epithelial tissues
Aboutaleb Amiri, Charlie Duclut, Frank Jülicher +1
We investigate how randomly oriented cell traction forces lead to fluidisation in a vertex model of epithelial tissues. We find that the fluidisation occurs at a critical value of…
Odd Cosserat elasticity in active materials
Piotr Surówka, Anton Souslov, Frank Jülicher +1
Stress-strain constitutive relations in solids with an internal angular degree of freedom can be modelled using Cosserat (also called micropolar) elasticity. In this paper, we expl…
A numerical approach for fluid deformable surfaces with conserved enclosed volume
Veit Krause, Axel Voigt
We consider surface finite elements and a semi-implicit time stepping scheme to simulate fluid deformable surfaces. Such surfaces are modeled by incompressible surface Navier-Stoke…
Broken living layers: dislocations in active smectics
Frank Julicher, Jacques Prost, John Toner
We show that dislocations in active 2d smectics with underlying rotational symmetry are always unbound in the presence of noise, meaning the active smectic phase does not exist for…
Phase separation induces congestion waves in electric vehicle charging
Philip Marszal, Marc Timme, Malte Schröder
Electric vehicles may dominate motorized transport in the next decade, yet the impact of the collective dynamics of electric mobility on long-range traffic flow is still largely un…
Learning stochastic filtering
Rahul O. Ramakrishnan, Andrea Auconi, Benjamin M. Friedrich
We quantify the performance of approximations to stochastic filtering by the Kullback-Leibler divergence to the optimal Bayesian filter. Using a two-state Markov process that drive…
Metrics reloaded: Recommendations for image analysis validation
Lena Maier-Hein, Annika Reinke, Patrick Godau +71
Increasing evidence shows that flaws in machine learning (ML) algorithm validation are an underestimated global problem. Particularly in automatic biomedical image analysis, chosen…
Lift force in odd compressible fluids
Ruben Lier, Charlie Duclut, Stefano Bo +3
We compute the response matrix for a tracer particle in a compressible fluid with odd viscosity living on a two-dimensional surface. Unlike the incompressible case, we find that an…
A meshfree collocation scheme for surface differential operators on point clouds
Abhinav Singh, Alejandra Foggia, Pietro Incardona +1
We present a meshfree collocation scheme to discretize intrinsic surface differential operators over scalar fields on smooth curved surfaces with given normal vectors and a non-int…
Energy and Matter Supply for Active Droplets
Jonathan Bauermann, Christoph A. Weber, Frank Jülicher
Chemically active droplets provide simple models for cell-like systems that can grow and divide. Such active droplet systems are driven away from thermodynamic equilibrium and turn…
On the role of mechanosensitive binding dynamics in the pattern formation of active surfaces
M. Bonati, L. D. Wittwer, S. Aland +1
The actin cortex of an animal cell is a thin polymeric layer attached to the inner side of the plasma membrane. It plays a key role in shape regulation and pattern formation on the…
Heat Fluctuations in Chemically Active Systems
Joël Mabillard, Christoph A. Weber, Frank Jülicher
Chemically active systems such as living cells are maintained out of thermal equilibrium due to chemical events which generate heat and lead to active fluctuations. A key question…
Effects of local curvature on epithelia tissue -- coordinated rotational movement and other spatiotemporal arrangements
Lea Happel, Dennis Wenzel, Axel Voigt
Coordinated movements of epithelia tissue are linked with active matter processes. We here consider the influence of curvature on the spatiotemporal arrangements and the shapes of…
