We control the diffusion of light in a disordered photonic waveguide by modulating the waveguide geometry. In a single waveguide of varying cross-section, the diffusion coefficient changes spatially in two dimensions due to localization effects. The intensity distribution inside the waveguide agrees with the prediction of the self-consistent theory of localization. Our work shows that wave diff...

Perturbation chromatography with multi component gas carrier and non-equilibrium thermodynamics liner law was applied for discussion of the interference effect and the displacement effect on mass transfer in multi component gas adsorption. Moment analysis method and stop & go simulation method were utilized to obtain each mass transfer parameters of adsorbate gases. Dependency of micropore diff...

Cross-diffusion may be an important driving force of pattern formation in population models. Recently, a relation between cross-diffusion and reaction-diffusion systems has been revealed from the mathematical modeling point view. In this paper, we derive predator–prey model with simple system two behavioral states predator examine whether can induce spatial patterns We assume that predators hav...

PURPOSE To correct distortions caused by eddy currents induced by large diffusion gradients during high angular resolution diffusion imaging without any auxiliary reference scans. MATERIALS AND METHODS Image distortion parameters were obtained by image coregistration, performed only between diffusion-weighted images with close diffusion gradient orientations. A linear model that describes dis...

Abstract. Theoretical approaches to earthquake instabilities propose shear-dominated source mechanisms. Here we take a fresh look at the role of possible volumetric preceding shear instability. We investigate phenomena that may prepare using coupling thermo-hydro-mechano-chemical reaction–diffusion equations in THMC diffusion matrix. show off-diagonal cross-diffusivities can give rise new class...

Glycols, aldehydes, and acrylamide inhibit the in vitro formation of cold cataracts in calf lenses. The inhibition is reversed when the glycols or the acrylamide are diffused out of the lenses. The inhibition by aldehydes or polacrylamide is irreversible, suggesting that the crosslinking reagents may permanently modify lens structure to prevent the development of lens opacities due to a phase t...

This paper describes a project which aims to investigate the extent of e-procurement usage at the organizational level and to examine the key factors that influence the extent of e-procurement usage in New Zealand (NZ) small and medium enterprises (SMEs). An integrated model is developed based on the Technology-OrganizationEnvironment (TOE) framework and Diffusion of Innovation (DOI) theory. It...

We focus on a system of two competing species with cross-diffusion and selfdiffusion. By constructing an appropriate auxiliary function, we derive the sufficient conditions such that there are no coexisting steady-state solutions to model. It is worth noting function constructed above applicable Dirichlet, Neumann Robin boundary conditions.

An experimental setup has been developed for successive photo-electrochemical etch and EIS measurement of semiconductor samples. Furthermore an algorithm based on electrochemical capacitance-voltage (ECV) has been developed for calculating dopant profile based on the measurements by developed setup. Phosphorous diffusion profile in p-type silicon was estimated by employing developed setup and a...
