Multicomponent reaction-diffusion processes on complex networks
, 2006 We study the reaction-diffusion process $A + B \to \emptyset$ on uncorrelated scale-free networks analytically. By a mean-field ansatz we derive analytical expressions for the particle pair-correlations and the particle density.

Logistic Growth Described by Birth-Death and Diffusion Processes
Mathematics, 2019 We consider the logistic growth model and analyze its relevant properties, such as the limits, the monotony, the concavity, the inflection point, the maximum specific growth rate, the lag time, and the threshold crossing time problem.

Inference with Non-Homogeneous Lognormal Diffusion Processes Conditioned on Nearest Neighbor
MathematicsIn this work, we approach the forecast problem for a general non-homogeneous diffusion process over time with a different perspective from the classical one.

A Note on Estimation of Multi-Sigmoidal Gompertz Functions with Random Noise
Mathematics, 2019 The behaviour of many dynamic real phenomena shows different phases, with each one following a sigmoidal type pattern. This requires studying sigmoidal curves with more than one inflection point. In this work, a diffusion process is introduced whose mean

Annihilation-diffusion processes: an exactly solvable model
, 2000 A family of diffusion-annihilation processes is introduced, which is exactly solvable. This family contains parameters that control the diffusion- and annihilation- rates. The solution is based on the Bethe ansatz and using special boundary conditions to

Computer-Aided Design in Electromagnetics - the Case for Surface Impedance Boundary Conditions
Advances in Electrical and Computer Engineering, 2012 Surface impedance boundary conditions (SIBCs) have been successfully used for over 70 years in both analytical and numerical computation. With the need to model increasingly complex geometries and smaller artifacts, its importance in computer-aided ...

Single-site approximation for reaction-diffusion processes
, 2006 We consider the branching and annihilating random walk $A\to 2A$ and $2A\to 0$ with reaction rates $\sigma$ and $\lambda$, respectively, and hopping rate $D$, and study the phase diagram in the $(\lambda/D,\sigma/D)$ plane.
