Propagating wave in the flock of self-propelled particles
Waipot Ngamsaad, Suthep Suantai
We investigate the linearized hydrodynamic equations of interacting self-propelled particles in two dimensional space. It is found that the small perturbations of density and polar…
Perturbative traveling wave solution for a flux-limited reaction-diffusion morphogenesis equation
Waipot Ngamsaad, Suthep Suantai
In this study, we investigate a porous medium-type flux limited reaction--diffusion equation that arises in morphogenesis modeling. This nonlinear partial differential equation is…
Mechanically-driven spreading of bacterial populations
Waipot Ngamsaad, Suthep Suantai
The effect of mechanical interactions between cells in the spreading of bacterial populations was investigated in one-dimensional space. A continuum-mechanics approach, comprising…
Radial propagation in population dynamics with density-dependent diffusion
Waipot Ngamsaad
The population dynamics that evolves in the radial symmetric geometry is investigated. The nonlinear reaction-diffusion model, which depends on population density, is employed as t…
Self-similar dynamics of bacterial chemotaxis
Waipot Ngamsaad, Kannika Khompurngson
Colonies of bacteria grown on thin agar plate exhibit fractal patterns as a result of adaptation to their environments. The bacterial colony pattern formation is regulated cruciall…
Self-Similar Solutions to a Density-Dependent Reaction-Diffusion Model
Waipot Ngamsaad, Kannika Khompurngson
In this paper, we investigated a density-dependent reaction-diffusion equation, . This equation is known as the extension of the Fisher or Kolmogoro…
