Diffusion mediated reaction models are particularly ubiquitous in the description of phys-ical, chemical or biological processes. The random walk schema is a useful tool for formu-lating these models. Recently, evanescent ...

An h-adaptive mesh procedure to solve the reaction-diffusion problem for multiple reactions in catalytic pellets presenting strong diffusion limitations is developed. The discretization approach selected for this purpose ...

Diffusion is one of the main transport processes that occur inside cells determining the spatial and time distribution of relevant action molecules. In most cases these molecules not only diffuse but also interact with ...

Apresentamos aqui um princípio de grandes desvios com a norma do supremo para o limite de altas densidades de um sistema de passeios aleatórios sobrepostos e independentes com uma dinâmica de nascimento e morte, que exibe ...

In this work, we are interested in the dynamic behavior of a parabolic problem with nonlinear boundary conditions and delay in the boundary. We construct a reaction-diffusion problem with delay in the interior, where the ...

In recent years, in-silico experimentation within the field of oncological medicine has been intensively investigated with the aim of better understanding tumor dynamics and dose–response relationships in cancer treatments. ...

In this work we consider a one-dimensional quasilinear parabolic equation and we prove that the lap number of any solution cannot increase through orbits as the time passes if the initial data is a continuous function. We ...

A method to simultaneously determine the chemical kinetics (kCT) and Langmuir’s adsorption equilibrium (KL) constants in porous catalyst particles where chemical reactions following Langmuir-Hinshel wood-Hougen-Watson ...
