Reaction-Diffusion-Advection Systems with Discontinuous Diffusion and Mass Control [PDF]
SIAM Journal on Mathematical Analysis, 2021 In this paper, we study unique, globally defined uniformly bounded weak solutions for a class of semilinear reaction-diffusion-advection systems. The coefficients of the differential operators and the initial data are only required to be measurable and uniformly bounded.

MHD and radiation effects on moving isothermal vertical plate with variable mass diffusion [PDF]
Theoretical and Applied Mechanics, 2006 An analysis is performed to study the effects of thermal radiation on unsteady free convective flow over a moving vertical plate with mass transfer in the presence of magnetic field. The fluid considered here is a gray, absorbing-emitting radiation but a

Abundance anomalies in pre-main-sequence stars: Stellar evolution models with mass loss [PDF]
, 2003 The effects of atomic diffusion on internal and surface abundances of A and F pre-main-sequence stars with mass loss are studied in order to determine at what age the effects materialize, as well as to further understand the processes at play in HAeBe ...

Gravitational settling in pulsating subdwarf B stars and their progenitors [PDF]
, 2009 Diffusion of atoms can be important during quiescent phases of stellar evolution. Particularly in the very thin inert envelopes of subdwarf B stars, diffusive movements will considerably change the envelope structure and the surface abundances on a short

COVID-19 and Mobile Payment Diffusion: Lessons for Future Mass Diffusion and Continual Usage
Journal of Innovation Management, 2022 Covid-19 transformed mobile payment services (MPS) diffusion pattern globally. Consequently, the need to examine factors contributing to the diffusion rate of MPS in this era is substantiated. Thus, this study employs Structural Equation Model (SEM) with

A Reduced-Order Model of Heat Transfer Effects on the Dynamics of Bubbles [PDF]
, 2002 The Rayleigh-Plesset equation has been used extensively to model spherical bubble dynamics, yet it has been shown that it cannot correctly capture damping effects due to mass and thermal diffusion.

Interface collisions with diffusive mass transport
Physical Review E, 2022 We report on a linear Langevin model that describes the evolution of the roughness of two interfaces that move towards each other and are coupled by a diffusion field. This model aims at describing the closing of the gap between two two-dimensional material domains during growth, and the subsequent formation of a rough grain boundary.
