Analysis of the Gibbs sampler for hierarchical inverse problems
Sergios Agapiou, Johnathan M. Bardsley, Omiros Papaspiliopoulos +1
Many inverse problems arising in applications come from continuum models where the unknown parameter is a field. In practice the unknown field is discretized resulting in a problem…
Topological orderings of weighted directed acyclic graphs
Dániel Gerbner, Balázs Keszegh, Cory Palmer +1
We call a topological ordering of a weighted directed acyclic graph non-negative if the sum of weights on the vertices in any prefix of the ordering is non-negative. We investigate…
Fixing numbers for matroids
Gary Gordon, Jennifer McNulty, Nancy Ann Neudauer
Motivated by work in graph theory, we define the fixing number for a matroid. We give upper and lower bounds for fixing numbers for a general matroid in terms of the size and maxim…
Solar wind reflection from the lunar surface: The view from far and near
L. Saul, P. Wurz, A. Vorburger +7
The Moon appears bright in the sky as a source of energetic neutral atoms (ENAs). These ENAs have recently been imaged over a broad energy range both from near the lunar surface, b…
