Agent-based Monte Carlo simulations for reaction-diffusion models, population dynamics, and epidemic spreading
Mohamed Swailem, Ulrich Dobramysl, Ruslan Mukhamadiarov +1
We provide an overview of Monte Carlo algorithms based on Markovian stochastic dynamics of interacting and reacting many-particle systems not in thermal equilibrium. These agent-ba…
Argentine ants regulate traffic flow with stopped individuals
Ulrich Dobramysl, Simon Garnier, Laure-Anne Poissonnier +2
We investigated the emerging traffic patterns of Argentine ants (Linepithema humile) as they navigated a narrow bridge between their nest and a food source. By tracking ant movemen…
Perturbative Field-Theoretical Analysis of Three-Species Cyclic Predator-Prey Models
Louie Hong Yao, Mohamed Swailem, Ulrich Dobramysl +1
We apply a perturbative Doi--Peliti field-theoretical analysis to the stochastic spatially extended symmetric Rock-Paper-Scissors (RPS) and May--Leonard (ML) models, in which three…
Computational methods and fast hybrid stochastic simulations for triangulation sensing and identifying principles of cell navigation in the brain
Ulrich Dobramysl, David Holcman
Brownian simulations can be used to generate statistics relevant for studying molecular interactions or trafficking. However, the concurrent simulation of many Brownian trajectorie…
Reconstructing a point source from diffusion fluxes to narrow windows in three dimensions
U. Dobramysl, D. Holcman
We develop a computational approach to locate the source of a steady-state gradient of diffusing particles from the fluxes through narrow windows distributed either on the boundary…
Triangulation sensing: how cells recover a source from diffusing particles in three dimensions
Ulrich Dobramysl, David Holcman
How can cells embedded into a gradient concentration triangulate the position of the source and migrate toward their final destination? The source triangulation requires to recover…
