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…

Scale dependence of distributions of hotspots
Michael Wilkinson, Boris Veytsman
We consider a random field in dimensions which is largely concentrated around small `hotspots', with `weights', . These weights may have a very broad distr…

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…
