Travelling waves in monostable and bistable stochastic partial differential equations

C Kuehn - Jahresbericht der Deutschen Mathematiker …, 2020 - Springer
In this review, we provide a concise summary of several important mathematical results for
stochastic travelling waves generated by monostable and bistable reaction-diffusion …

[HTML][HTML] Stochastic simulation of reaction-diffusion systems: A fluctuating-hydrodynamics approach

C Kim, A Nonaka, JB Bell, AL Garcia… - The Journal of chemical …, 2017 - pubs.aip.org
We develop numerical methods for stochastic reaction-diffusion systems based on
approaches used for fluctuating hydrodynamics (FHD). For hydrodynamic systems, the FHD …

Deterministic versus stochastic cell polarisation through wave-pinning

GR Walther, AFM Marée, L Edelstein-Keshet… - Bulletin of mathematical …, 2012 - Springer
Cell polarization is an important part of the response of eukaryotic cells to stimuli, and forms
a primary step in cell motility, differentiation, and many cellular functions. Among the …

Velocity fluctuations of population fronts propagating into metastable states

B Meerson, PV Sasorov, Y Kaplan - … Review E—Statistical, Nonlinear, and Soft …, 2011 - APS
The position of propagating population fronts fluctuates because of the discreteness of the
individuals and stochastic character of processes of birth, death, and migration. Here we …

Stochastic desertification

H Weissmann, NM Shnerb - Europhysics Letters, 2014 - iopscience.iop.org
The process of desertification is usually modeled as a first-order transition, where a change
of an external parameter (eg, precipitation) leads to a catastrophic bifurcation followed by an …

Front propagation in a spatial system of weakly interacting networks

E Khain, M Iyengar - Physical Review E, 2023 - APS
We consider the spread of epidemic in a spatial metapopulation system consisting of weakly
interacting patches. Each local patch is represented by a network with a certain node degree …

Two-level modeling of quarantine

E Khain - Physical Review E, 2020 - APS
Continuum models of epidemics do not take into account the underlying microscopic
network structure of social connections. This drawback becomes extreme during quarantine …

Comparative Analysis of Fluctuations in Viscoelastic Stress: A Comparison of the Temporary Network and Dumbbell models

A Winters, HC Öttinger, J Vermant - arXiv preprint arXiv:2404.19743, 2024 - arxiv.org
Traditionally, stress fluctuations in flowing and deformed materials are overlooked, with an
obvious focus on average stresses in a continuum mechanical approximation. However …

Phase coexistence in a weakly stochastic reaction-diffusion system

Y Yanagisawa, S Sasa - arXiv preprint arXiv:2403.19198, 2024 - arxiv.org
We investigate phase coexistence in a weakly stochastic reaction-diffusion system without
assuming a continuum description. Concretely, for $(2N+ 1) $ diffusion-coupled vessels in …

Comparing methods for modelling spreading cell fronts

DC Markham, MJ Simpson, PK Maini… - Journal of Theoretical …, 2014 - Elsevier
Spreading cell fronts play an essential role in many physiological processes. Classically,
models of this process are based on the Fisher–Kolmogorov equation; however, such …
