X-ray Multimodal Intrinsic-Speckle-Tracking

Konstantin M. Pavlov, David M. Paganin, Heyang Li +3

We develop X-ray Multi-modal Intrinsic-Speckle-Tracking (MIST), a form of X-ray speckle-tracking that is able to recover both the position-dependent phase shift and the position-de…

A free boundary problem for spreading under shifting climate

Yuanyang Hu, Xinan Hao, Xianfa Song +1

In this paper we consider a free boundary problem which models the spreading of an invasive species whose spreading is enhanced by the changing climate. We assume that the climate…

Single-shot x-ray speckle-based imaging of a single-material object

Konstantin M. Pavlov, Heyang, Li +4

We develop a means for speckle-based phase imaging of the projected thickness of a single-material object, under the assumption of illumination by spatially random time-independent…

Feasible bases for a polytope related to the Hamilton cycle problem

Thomas Kalinowski, Sogol Mohammadian

We study a certain polytope depending on a graph and a parameter which arises from embedding the Hamiltonian cycle problem in a discounted Markov decision process.…

Small gauge transformations and universal geometry in heterotic theories

Jock McOrist, Roberto Sisca

The first part of this paper describes in detail the action of small gauge transformations in heterotic supergravity. We show a convenient gauge fixing is `holomorphic gauge' toget…

Monotonicity of the principal eigenvalue for a linear time-periodic parabolic operator

Shuang Liu, Yuan Lou, Rui Peng +1

We investigate the effect of frequency on the principal eigenvalue of a time-periodic parabolic operator with Dirichlet, Robin or Neumann boundary conditions. The monotonicity and…
