Tunable intracellular transport on converging microtubule morphologies

Autor: Niranjan Sarpangala, Brooke Randell, Ajay Gopinathan, Oleg Kogan

Publikováno v: Biophysical Reports, Vol 4, Iss 3, Pp 100171- (2024)

A common type of cytoskeletal morphology involves multiple microtubules converging with their minus ends at the microtubule organizing center (MTOC). The cargo-motor complex will experience ballistic transport when bound to microtubules or diffusive

Fisher-Kolmogorov-Petrovsky-Piskunov dynamics mediated by a parent field with a delay

Autor: Oleg Kogan, Steffanie Stanley

Publikováno v: Physical review. E. 104(3-1)

We examine a modification of the Fisher-Kolmogorov-Petrovsky-Piskunov (FKPP) process in which the diffusing substance requires a parent density field for reproduction. A biological example would be the density of diffusing spores (propagules) and the

The role of advective transport mechanism in continental-scale transport of fungal plant epidemics

Autor: Kush Unadhyay, Nolan Patrick Elauria, Taeah Truong, Oleg Kogan

In examining the continental-scale plant pathogen spread, we focus on the competition between the short-range stochastic hopping within the atmospheric boundary layer, and the laminar advection by the currents in the free troposphere. The latter is t

Advancing an interdisciplinary framework to study seed dispersal ecology

Publikováno v: AoB PLANTS, vol 12, iss 2
AoB Plants

Although dispersal is generally viewed as a crucial determinant for the fitness of any organism, our understanding of its role in the persistence and spread of plant populations remains incomplete. Generalizing and predicting dispersal processes are

Path-dependent course of epidemic: are two phases of quarantine better than one?

Autor: Evgeniy Khain, Varun Nimmagadda, Oleg Kogan

The importance of a strict quarantine has been widely debated during the COVID-19 epidemic even from the purely epidemiological point of view. One argument against strict lockdown measures is that once the strict quarantine is lifted, the epidemic co

Employing plant functional groups to advance seed dispersal ecology and conservation

Publikováno v: AoB Plants
AoB PLANTS, vol 11, iss 2

Seed dispersal enables plants to reach hospitable germination sites and escape natural enemies. Understanding when and how much seed dispersal matters to plant fitness is critical for understanding plant population and community dynamics. At the same

As the single opportunity for plants to move, seed dispersal has an important impact on plant fitness, species distributions and patterns of biodiversity. However, models that predict dynamics such as risk of extinction, range shifts and biodiversity

Fragility of reaction-diffusion models with respect to competing advective processes

Autor: Christopher R. Myers, Kevin P. O'Keeffe, Oleg Kogan

Publikováno v: Physical review. E. 96(2-1)

We study the coupling of a Fisher-Kolmogorov-Petrovsky-Piskunov (FKPP) equation to a separate, advection-only transport process. We find that an infinitesimal coupling can cause a finite change in the speed and shape of the reaction front, indicating

Two-strain competition in quasi-neutral stochastic disease dynamics

Autor: David J. Schneider, Christopher R. Myers, Baruch Meerson, Michael Khasin, Oleg Kogan

We develop a perturbation method for studying quasineutral competition in a broad class of stochastic competition models and apply it to the analysis of fixation of competing strains in two epidemic models. The first model is a two-strain generalizat

Subharmonic Resonance Cascades in a Class of Coupled Resonators

Autor: Steven W. Shaw, Oleg Kogan, B. Scott Strachan

Publikováno v: Journal of Computational and Nonlinear Dynamics. 8

We consider a chain of N nonlinear resonators with natural frequency ratios of approximately 2:1 along the chain and weak nonlinear coupling of a form that allows energy to flow between resonators. Specifically, the coupling is such that the response
