Generation of Large Scale Magnetic Fields by Cross Field Diffusion [PDF]

open access: yesJournal of Astronomy and Space Sciences, 1987
The possibility of the cross-field diffusion of a fluid to generate magnetic fields on a large scale is examined. Application to the sunspot is discussed.

Diffusion of the internet : a cross-country analysis [PDF]

open access: yes
This paper analyzes the process of Internet diffusion across the world using a panel of 199 countries during 1990-2004. The authors group countries in two categories-low and high-income countries-and show that the Internet diffusion process is well ...

Cross-diffusion in Biofilms

open access: yes, 2015
We propose a deterministic continuum model for mixed culture biofilms where movement of one species is affected by the presence of the other. Two derivations of this new model are presented. One derivation is based on the continuous time, discrete space master equation and the other one is based on the equations of conservation of mass and momentum ...

On a Cross-Diffusion Model in Ecohydrology: Theory and Numerics

open access: yesActa Applicandae Mathematicae
Abstract In this paper, we consider a version of the mathematical model introduced in (Wang et al. in Commun. Nonlinear Sci. Numer. Simul. 42:571–584, 2017) to describe the interaction between vegetation and soil water in arid environments. The model corresponds to a nonlinear parabolic coupled system of partial differential equations, with ...
