A Stable Mode of Dendritic Growth in Cases of Conductive and Convective Heat and Mass Transfer

open access: yesCrystals, 2022
In this paper, we develop a theory of stable dendritic growth in undercooled melts in the presence of conductive and convective heat and mass transfer boundary conditions at the solid/liquid interface of a dendrite.

Optimal Parameter Upscaling for Partial Differential Equation Models in Mathematical Biology [PDF]

open access: yes, 2022
Partial differential equation models in mathematical biology often involve space-dependent parameters, such as diffusion coefficients and advection fields, that cannot be measured explicitly and are therefore uncertain. In this work, we compute spatially
