Master equations and the theory of stochastic path integrals

MF Weber, E Frey - Reports on Progress in Physics, 2017 - iopscience.iop.org
This review provides a pedagogic and self-contained introduction to master equations and
to their representation by path integrals. Since the 1930s, master equations have served as …

Multicellular tumor spheroid in an off-lattice Voronoi-Delaunay cell model

G Schaller, M Meyer-Hermann - Physical Review E—Statistical, Nonlinear, and …, 2005 - APS
We study multicellular tumor spheroids by introducing a new three-dimensional agent-based
Voronoi-Delaunay hybrid model. In this model, the cell shape varies from spherical in thin …

[HTML][HTML] Monte Carlo simulations of enzyme reactions in two dimensions: fractal kinetics and spatial segregation

H Berry - Biophysical journal, 2002 - cell.com
Conventional equations for enzyme kinetics are based on mass-action laws, that may fail in
low-dimensional and disordered media such as biological membranes. We present Monte …

Phase transitions and spatio-temporal fluctuations in stochastic lattice Lotka–Volterra models

M Mobilia, IT Georgiev, UC Täuber - Journal of Statistical Physics, 2007 - Springer
We study the general properties of stochastic two-species models for predator-prey
competition and coexistence with Lotka–Volterra type interactions defined on ad …

Clustering, advection, and patterns in a model of population dynamics with neighborhood-dependent rates

E Hernández-García, C López - Physical Review E—Statistical, Nonlinear, and …, 2004 - APS
We introduce a simple model of population dynamics which considers reproducing
individuals or particles with birth and death rates depending on the number of other …

Delaunay-Object-Dynamics: cell mechanics with a 3D kinetic and dynamic weighted Delaunay-triangulation

M Meyer-Hermann - Current topics in developmental biology, 2008 - Elsevier
Mathematical methods in Biology are of increasing relevance for understanding the control
and the dynamics of biological systems with medical relevance. In particular, agent-based …

Continuum versus discrete model: a comparison for multicellular tumour spheroids

G Schaller, M Meyer-Hermann - … Transactions of the …, 2006 - royalsocietypublishing.org
We study multicellular tumour spheroids with a continuum model based on partial differential
equations (PDEs). The model includes viable and necrotic cell densities, as well as oxygen …

Field theories and quantum methods for stochastic reaction-diffusion systems

MJ del Razo, T Lamma, W Merbis - arxiv preprint arxiv:2409.13377, 2024 - arxiv.org
Complex systems are composed of many particles or agents that move and interact with one
another. The underlying mathematical framework to model many of these systems must …

Transition phenomena induced by internal noise and quasi-absorbing state

J Ohkubo, N Shnerb, D A. Kessler - Journal of the Physical Society of …, 2008 - journals.jps.jp
We study a simple chemical reaction system and effects of the internal noise. The chemical
reaction system causes the same transition phenomenon discussed by Togashi and Kaneko …

Influence of local carrying capacity restrictions on stochastic predator–prey models

MJ Washenberger, M Mobilia… - Journal of Physics …, 2007 - iopscience.iop.org
We study a stochastic lattice predator–prey system by means of Monte Carlo simulations that
do not impose any restrictions on the number of particles per site, and discuss the …
