Restricted gas diffusion in a unique porous medium — human lung [PDF]
, 2009 Restricted diffusion of gas in the lung is in many ways similar to restricted diffusion in other porous media: atomic collisions with boundaries restrict the measured value, and there is a critical dependence on the time and distance scales of the ...

New Analytical Results and Numerical Schemes for Irregular Diffusion Processes [PDF]
, 2022 We examine the transient diffusion equation with time- and space-dependent diffusion coefficients in 1D. Such transport equations can be easily derived from the Fokker-Planck equation and are essential to understand the diffusion mechanisms in general, e.
