Thermodynamic inference from noisy single-molecule time series
Todd R. Gingrich, Oleg A. Igoshin, Anatoly B. Kolomeisky +1
Single-molecule or single-particle tracking measurements inherently yield noisy microscopic trajectories, often significantly constrained by the diffraction limit and by the finite…
Quantum field theory approach for multistage chemical kinetics in liquids
Roman V. Li, Oleg A. Igoshin, Evgeny B. Krissinel +1
Reaction-diffusion processes play an important role in a variety of physical, chemical, and biological systems. Conventionally, the kinetics of these processes are described by the…
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…
Existence of weak solutions for the kinetic models of motion of myxobacteria with alignment and reversals
Patrick Murphy, Oleg Igoshin, Misha Perepelitsa +1
In this paper, we consider three non-linear kinetic partial differential equations that emerge in the modeling of motion of rod-shaped cells such as myxobacteria. This motion is ch…
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…
Biophysics at the coffee shop: lessons learned working with George Oster
Oleg Igoshin, Jing Chen, Jianhua Xing +9
Over the past 50 years, the use of mathematical models, derived from physical reasoning, to describe molecular and cellular systems has evolved from an art of the few to a cornerst…
Modeling mechanical interactions in growing populations of rod-shaped bacteria
James J. Winkle, Oleg Igoshin, Matthew R. Bennett +2
Advances in synthetic biology allow us to engineer bacterial collectives with pre-specified characteristics. However, the behavior of these collectives is difficult to understand,…
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…
