Aggregation-diffusion equations and gradient flows form a dynamic field of study at the intersection of mathematical analysis, statistical mechanics and applied physics. These equations characterise ...

New work describes vital aspects of diffusion processes in tissue development, including the roles that molecular diffusion gradients have on stem cell signaling pathways along with new modeling tools ...

Facilitated transport of oxygen through hemoglobin has been studied by use of a membrane sandwich of hemoglobin, Teflon, and water, Transport is enhanced only when there is a hemoglobin-bound-O$_{2}$ ...
