Spatial pattern formation in reaction–diffusion models: a computational approach
Sign Up to like & getrecommendations! Published in 2020 at "Journal of Mathematical Biology"
DOI: 10.1007/s00285-019-01462-0
Abstract: Reaction–diffusion equations have been widely used to describe biological pattern formation. Nonuniform steady states of reaction–diffusion models correspond to stationary spatial patterns supported by these models. Frequently these steady states are not unique and correspond… read more here.

DOI: 10.1016/j.actamat.2019.10.058
Abstract: Abstract Severe plastic deformation is a widespread method of making high-performance metallic materials. Single-phase polycrystalline metals undergoing severe plastic deformation develop steady-state textures that are characteristic of the mode of deformation. By contrast, we show… read more here.
