Query: Higher-order models for glioma invasion: from a two-scale description to
  effective equations for mass density and momentum   Starting from a two-scale description involving receptor binding dynamics and
a kinetic transport equation for the evolution of the cell density function
under velocity reorientations, we deduce macroscopic models for glioma invasion
featuring partial differential equations for the mass density and momentum of a
population of glioma cells migrating through the anisotropic brain tissue. The
proposed first and higher order moment closure methods enable numerical
simulations of the kinetic equation. Their performance is then compared to that
of the diffusion limit. The approach allows for DTI-based, patient-specific
predictions of the tumor extent and its dynamic behavior.
