Combined Experimental Approach and Finite Element Modeling of Small Molecule Transport Through Joint Synovium to Measure Effective Diffusivity. [PDF]
J Biomech Eng, 2020 Trans-synovial solute transport plays a critical role in the clearance of intra-articularly delivered drugs. In this study, we present a computational finite element model of solute transport through the synovium validated by experiments on synovial ...

Brownian yet Non-Gaussian Diffusion: From Superstatistics to Subordination of Diffusing Diffusivities [PDF]
Physical Review X, 2017 A growing number of biological, soft, and active matter systems are observed to exhibit normal diffusive dynamics with a linear growth of the mean-squared displacement, yet with a non-Gaussian distribution of increments.

Indirect Diffusion Effect in Degenerate Reaction-Diffusion Systems [PDF]
SIAM Journal on Mathematical Analysis, 2020 In this work we study global well-posedness and large time behaviour for a typical reaction--diffusion system, which include degenerate diffusion, and whose non-linearities arise from chemical reactions. We show that there is an {\it indirect diffusion effect}, i.e. an effective diffusion for the non-diffusive species which is incurred by a combination

Drying and color in punamuña leaves (Satureja boliviana)
Dyna, 2021 Drying allows water to be removed and food to be preserved, however, this operation can degrade color. Punamuña leaves are aromatic and used for medicinal purposes in the Peruvian Andes. This research aimed to determine and model the drying kinetics, the
