Brain pulsations enhance cerebrospinal fluid flow in perivascular spaces
Gregory Holba, James P. Hague, Nigel Hoggard +1
A novel approach is adopted to model cerebrospinal fluid (CSF) flow in human perivascular spaces (PVSs) surrounding brain-penetrating arteries. It is proposed that the outer PVS bo…
Elastic displacements and viscous hydrodynamic flows in wedge-shaped geometries with a straight edge: Green's functions for parallel forces
Abdallah Daddi-Moussa-Ider, Lukas Fischer, Marc Pradas +1
For homogeneous and isotropic linearly elastic solids and for incompressible fluids under low-Reynolds-number conditions the fundamental solutions of the associated continuum equat…
Rotational dynamics of a disk in a thin film of weakly nematic fluid subject to linear friction
Abdallah Daddi-Moussa-Ider, Elsen Tjhung, Marc Pradas +2
Dynamics at low Reynolds numbers experiences recent revival in the fields of biophysics and active matter. While in bulk isotropic fluids it is exhaustively studied, this is less s…
Dynamics of pivoted slider bearings
Andrew Wilkinson, Marc Pradas, Michael Wilkinson
We obtain the full equations of motion for a wide, pivoted, slider bearing. These are used to review the choice of the optimal position for the pivot point, to discuss its response…
Flux-conserving directed percolation
Barto Cucurull, Greg Huber, Kyle Kawagoe +3
We discuss a model for directed percolation in which the flux of material along each bond is a dynamical variable. The model includes a physically significant limiting case where t…
