Investigating effects from restricted diffusion in multi-component diffusion data [PDF]

, 2014
We have investigated model systems in which effects from non-Gaussian restricted diffusion could be separated from effects caused by multiple diffusion coefficients. We applied various models to analyze the experimental data.

Hölder inequality applied on a non-Newtonian fluid equation with a nonlinear convection term and a source term

Journal of Inequalities and Applications, 2018
Consider a non-Newtonian fluid equation with a nonlinear convection term and a source term. The existence of the weak solution is proved by Simon’s compactness theorem.

Bistable equation with discontinuous density dependent diffusion with degenerations and singularities

Electronic Journal of Qualitative Theory of Differential Equations, 2021
In this article we introduce rather general notion of the stationary solution of the bistable equation which allows to treat discontinuous density dependent diffusion term with singularities and degenerations, as well as degenerate or non-Lipschitz ...

Using Diffusion-Diffusion Exchange Spectroscopy to observe diffusion exchange in yeast [PDF]

, 2019
The permeability of cell membranes varies significantly across both healthy and diseased tissue, and changes in cell membrane permeability can occur during treatment response in tumours.

Principal spectral theory and asymptotic behavior of the spectral bound for partially degenerate nonlocal dispersal systems

Advanced Nonlinear Studies
The purpose of this paper is to investigate the principal spectral theory and asymptotic behavior of the spectral bound for cooperative nonlocal dispersal systems, specifically focusing on the case where partial diffusion coefficients are zero, referred ...

Creeping fronts in degenerate reaction–diffusion systems [PDF]

Nonlinearity, 2005
We study systems of reaction diffusion type for two species in one space dimension and investigate the dynamics in the case where the second species does not diffuse. We consider competing species with two stable equilibria and front solutions that connect the two stable states. A free energy function determines a preferred state.

Neuropsychological and Educational Outcomes in Shwachman–Diamond Syndrome—A Report From the North American Shwachman–Diamond Syndrome Registry

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Shwachman–Diamond syndrome (SDS) is a rare autosomal recessive ribosomopathy characterized by bone marrow failure and multisystem involvement, with emerging evidence of associated neurocognitive impairment. Methods We conducted a retrospective study of 240 individuals with biallelic Shwachman–Bodian–Diamond syndrome (SBDS) mutations

Global martingale solutions to a stochastic degenerate cross-diffusion ion transport system with volume-filling

Boundary Value Problems
The existence of global martingale solutions to a stochastic degenerate cross-diffusion system is shown. Previous results have shown that for some non-degenerate stochastic cross-diffusion systems, martingale solutions exist.

The effective density of randomly moving electrons and related characteristics of materials with degenerate electron gas

AIP Advances, 2014
Interpretation of the conductivity of metals, of superconductors in the normal state and of semiconductors with highly degenerate electron gas remains a significant issue if consideration is based on the classical statistics.
