The pattern of nodal morphogen signaling is shaped by co-receptor expression
eLife, 2021 Embryos must communicate instructions to their constituent cells over long distances. These instructions are often encoded in the concentration of signals called morphogens.

Geometrically-exact time-integration mesh-free schemes for advection-diffusion problems derived from optimal transportation theory and their connection with particle methods [PDF]
, 2017 We develop an Optimal Transportation Meshfree (OTM) particle method for advection-diffusion in which the concentration or density of the diffusive species is approximated by Dirac measures.

Progress in mixed Eulerian-Lagrangian finite element simulation of forming processes [PDF]
, 1990 A review is given of a mixed Eulerian-Lagrangian finite element method for simulation of forming processes. This method permits incremental adaptation of nodal point locations independently from the actual material displacements.
