Role of Non-Exponential Reversal times in Aggregation Models of Bacterial Populations
Michael Batista, Patrick Murphy, Oleg A. Igoshin +2
In this paper, we consider 1D agent-based and kinetic models of aggregation with reversals. In particular, we fit a Gamma distribution to represent the run times in myxobacteria an…
Breakdown of Boltzmann-type Models for the Alignment of Self-propelled Rods
Patrick Murphy, Misha Perepelitsa, Ilya Timofeyev +3
Studies in the collective motility of organisms use a range of analytical approaches to formulate continuous kinetic models of collective dynamics from rules or equations describin…
A mean-field model for nematic alignment of self-propelled rods
Misha Perepelitsa, Ilya Timofeyev, Patrick Murphy +1
In this paper we develop a model for nematic alignment of self-propelled rods interacting through binary collisions. We avoid phenomenological descriptions of rod interaction in fa…
The energy cost and optimal design of networks for biological discrimination
Qiwei Yu, Anatoly B. Kolomeisky, Oleg A. Igoshin
Many biological processes discriminate between correct and incorrect substrates through the kinetic proofreading mechanism which enables lower error at the cost of higher energy di…
Mechanism for collective cell alignment in Myxococcus xanthus bacteria
Rajesh Balagam, Oleg A. Igoshin
Myxococcus xanthus cells self-organize into aligned groups, clusters, at various stages of their lifecycle. Formation of these clusters is crucial for the complex dynamic multi-cel…
Myxococcus xanthus gliding motors are elastically coupled to the substrate as predicted by the focal adhesion model of gliding motility
Rajesh Balagam, Douglas B. Litwin, Fabian Czerwinski +4
Myxococcus xanthus is a model organism for studying bacterial social behaviors due to its ability to form complex multi-cellular structures. Knowledge of M. xanthus surface gliding…
