Energetics of stochastic limit-cycle oscillators: when does coupling reduce dissipation?
Anton F. Burnet, Vansh Kharbanda, David Tobias +1
Non-linear oscillators serve important functions in many biological systems, including within the inner ear and neuronal networks. The sustainment of oscillations in noisy environm…
State-dependent recruitment of adhesion molecules enables perfect stabilization in cell-adhesion models
Anton F. Burnet, Julia Müllner, Benedikt Sabass
Cells adapt their adhesion to mechanical load, but the physical conditions under which this response prevents rupture remain unclear. Inspired by focal adhesions, we study models i…
Sparse inference and active learning of stochastic differential equations from data
Yunfei Huang, Youssef Mabrouk, Gerhard Gompper +1
Automatic machine learning of empirical models from experimental data has recently become possible as a result of increased availability of computational power and dedicated algori…
A generic self-stabilization mechanism for biomolecular adhesions under load
Andrea Braeutigam, Ahmet Nihat Simsek, Gerhard Gompper +1
Mechanical loading generally weakens adhesive structures and eventually leads to their rupture. However, biological systems can adapt to loads by strengthening adhesions, which is…
Non-equilibrium dynamics of bacterial colonies -- growth, active fluctuations, segregation, adhesion, and invasion
Kai Zhou, Marc Hennes, Berenike Maier +2
Colonies of bacteria endowed with a pili-based self-propulsion machinery are ideal models for investigating the structure and dynamics of active many-particle systems. We study Nei…
A Bayesian traction force microscopy method with automated denoising in a user-friendly software package
Yunfei Huang, Gerhard Gompper, Benedikt Sabass
Adherent biological cells generate traction forces on a substrate that play a central role for migration, mechanosensing, differentiation, and collective behavior. The established…
Traction force microscopy with optimized regularization and automated Bayesian parameter selection for comparing cells
Yunfei Huang, Christoph Schell, Tobias B. Huber +5
Adherent cells exert traction forces on to their environment, which allows them to migrate, to maintain tissue integrity, and to form complex multicellular structures. This tractio…
Verticalization of bacterial biofilms
Farzan Beroz, Jing Yan, Yigal Meir +4
Biofilms are communities of bacteria adhered to surfaces. Recently, biofilms of rod-shaped bacteria were observed at single-cell resolution and shown to develop from a disordered,…
Fluctuating, Lorentz-force-like coupling of Langevin equations and heat flux rectification
Benedikt Sabass
In a description of physical systems with Langevin equations, interacting degrees of freedom are usually coupled through symmetric parameter matrices. This coupling symmetry is a c…
Collective force generation by groups of migrating bacteria
Benedikt Sabass, Howard A. Stone, Joshua W. Shaevitz
From biofilm and colony formation in bacteria to wound healing and embryonic development in multicellular organisms, groups of living cells must often move collectively. While cons…
Role of the membrane for mechanosensing by tethered channels
Benedikt Sabass, Howard A. Stone
Biologically important membrane channels are gated by force at attached tethers. Here, we generically characterize the non-trivial interplay of force, membrane tension, and channel…
Energy transfer in networks with local magnetic time-reversal symmetry breaking
Benedikt Sabass
Time-reversal symmetry of most conservative forces constrains the properties of linear transport in most physical systems. Here, I study the efficiency of energy transfer in oscill…
Nonlinear, electrocatalytic swimming in the presence of salt
Benedikt Sabass, Udo Seifert
A small, bimetallic particle in a hydrogen peroxide solution can propel itself by means of an electrocatalytic reaction. The swimming is driven by a flux of ions around the particl…
Dynamics and efficiency of a self-propelled, diffusiophoretic swimmer
Benedikt Sabass, Udo Seifert
Active diffusiophoresis - swimming through interaction with a self-generated, neutral, solute gradient - is a paradigm for autonomous motion at the micrometer scale. We study this…
Efficiency of surface-driven motion: nano-swimmers beat micro-swimmers
Benedikt Sabass, Udo Seifert
Surface interactions provide a class of mechanisms which can be employed for propulsion of micro- and nanometer sized particles. We investigate the related efficiency of externally…
