From single-file diffusion to two-dimensional cage diffusion and generalization of the totally asymmetric simple exclusion process to higher dimensions
(American Physical Society, 2016-01)
A two-dimensional constrained diffusion model is presented and characterized by numerical simulations. The model generalizes the one-dimensional single-file diffusion model by considering a cage diffusion constraint induced ...
From free to effective diffusion coefficients in fluorescence correlation spectroscopy experiments
(American Physical Society, 2013-02-13)
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 ...
KINETIC-STUDY OF LITHIUM ELECTROINSERTION IN TITANIUM-OXIDE THIN-FILMS

Nitrogen diffusion in niobium under low pressure
The interaction among heavy interstitial atoms present in metals with bcc structure is studied using anelastic spectroscopy. This technique makes it possible to obtain information on interstitial concentration, precipitation, ...
Oxygen diffusion in soils: Understanding the factors and processes needed for modeling
(Inst Investigaciones Agropecuarias, 2015)
Oxygen is an important element for plant growth. Reducing its concentration in the soil affects plant physiological processes such as nutrient and water uptake as well as respiration, the redox potential of soil elements ...
Modelling Diffusion Effects in Fertility Transition
Mathematical models bind theory to precise formulations, and by doing so accentuate logical inconsistences in theories and facilitate their testing. In this article we explore the implications of simple mathematical models ...
Numerical correction for the diffuse solar irradiance by the melo-escobedo shadowring measuring method
The present paper deals with numerical corrections factors proposed as a function of the clearness index in order to correct the diffuse solar irradiance measured with the Melo-Escobedo Shadowring Measuring Method (ME ...
Comparison Results for Reflected Jump-diffusions in the Orthant with Variable Reflection Directions and Stability Applications
(UNIV WASHINGTON, DEPT MATHEMATICS, 2008-10-30)
We consider reflected jump-diffusions in the orthant Rn + with time- and state-dependent drift, diffusion and jump-amplitude coefficients. Directions of reflection upon hitting boundary faces are also allow to depend ...
