Bayesian comparison of Langevin dynamics for cell motility from positional observation
Yusuke Kato, Jan Albrecht, Ted Moldenhawer +2
We develop a Bayesian framework for model comparison of second-order Langevin dynamics from position-only trajectories. While approximate increment likelihoods for nonlinear positi…
Likelihood-Based Heterogeneity Inference Reveals Non-Stationary Effects in Biohybrid Cell-Cargo Transport
Jan Albrecht, Lara S. Dautzenberg, Manfred Opper +2
Variability of motility behavior in populations of microbiological agents is a ubiquitous phenomenon even in the case of genetically identical cells. Accordingly, passive objects i…
The random walk of intermittently self-propelled particles
Agniva Datta, Carsten Beta, Robert GroÃmann
Motivated by various recent experimental findings, we propose a dynamical model of intermittently self-propelled particles: active particles that recurrently switch between two mod…
A mass conserved reaction-diffusion system reveals switching between coexisting polar and oscillatory cell motility states
Jack M. Hughes, Cristina Martinez-Torres, Carsten Beta +2
Motile eukaryotic cells display distinct modes of migration that often occur within the same cell type. It remains unclear, however, whether transitions between the migratory modes…
Deciphering the dual chemotaxis strategy of bacteria in porous media
Sönke Beier, Veronika Pfeifer, Agniva Datta +2
Chemotaxis of bacterial swimmers that move in a run-and-turn pattern is well studied in uniform bulk fluid. It is primarily based on modulating the run time in dependence on the sw…
