One-dimensional Wiener process with the properties of partial reflection and delay
In this paper, we construct the two-parameter semigroup of operators associated with a certain one-dimensional inhomogeneous diffusion process and study its properties.

An approach for studying stochastical diffusion flows of admixture particles in bodies of multiphase randomly nonhomogeneous structures is proposed, according to which initialboundary value problems of diffusion are formulated for flow functions and ...

Wind energy production by means of diffusion stochastic process. Parameters estimation [PDF]
In this work, we attempt to model wind energy production via a stochastic diffusion process. We consider an Ito-type stochastic differential * equation (SDE) and determine the probabilistic characteristics of the stochastic process solution, particularly

Interpolation process between standard diffusion and fractional diffusion [PDF]
We consider a Hamiltonian lattice field model with two conserved quantities, energy and volume, perturbed by stochastic noise preserving the two previous quantities.

Reaction-diffusion processes with nonlinear diffusion [PDF]
We study reaction-diffusion processes with concentration-dependent diffusivity. First, we determine the decay of the concentration in the single-species and two-species diffusion-controlled annihilation processes. We then consider two natural inhomogeneous realizations.

Stochastic Processes Crossing from Ballistic to Fractional Diffusion with Memory: Exact Results [PDF]
We address the now classical problem of a diffusion process that crosses over from a ballistic behavior at short times to a fractional diffusion (sub- or super-diffusion) at longer times. Using the standard non-Markovian diffusion equation we demonstrate

Mathematical modeling of an optimal oncotherapy for malignant tumors [PDF]
The paper presents a mathematical model of the optimal treatment for malignant neoplasms. The neoplasm is considered as a distributed parameter object. The scheme for an optimal oncotherapy using a system of partial differential equations of parabolic ...

Reaction-diffusion systems in natural sciences and new technology transfer
Diffusion mechanisms in natural sciences and innovation management involve partial differential equations (PDEs). This is due to their spatio-temporal dimensions.

Asymptotic Behavior on a Linear Self-Attracting Diffusion Driven by Fractional Brownian Motion
Let BH={BtH,t≥0} be a fractional Brownian motion with Hurst index 12≤H0 and σ,ν∈R are three parameters. The process is an analogue of the self-attracting diffusion (Cranston and Le Jan, Math. Ann.303 (1995), 87–93).
