TL;DR: The XMM-Newton Medium Sensitivity Survey (XMS) as mentioned in this paper provides an unbiased and quantitative description of the X-ray source population at these fluxes and in various Xray energy bands.
Asymptotic Expansions for Closed Orbits in Homology Classes
Mark Pollicott,Richard Sharp +1 more
TL;DR: In this article, the behaviour of the counting function associated to the closed geodesics lying in a prescribed homology class on a compact negatively curved manifold was studied and the main result is an asymptotic expansion.

TL;DR: The XMM-Newton Medium Sensitivity Survey (XMS) as mentioned in this paper consists of four largely overlapping source samples selected at soft (0.5-2 keV), intermediate (0.,5-4.5 keV) and hard (2-10 keV).
Orbit counting for some discrete groups acting on simply connected manifolds with negative curvature
Mark Pollicott,Richard Sharp +1 more
TL;DR: In this paper, the authors developed a method of deriving asymptotic formulae for the orbital counting function for the action of certain discrete groups of isometries of simply connected negatively curved manifolds.

An entropy based theory of the grain boundary character distribution
Katayun Barmak,Eva Eggeling,Maria Emelianenko,Yekaterina Epshteyn,David Kinderlehrer,Richard Sharp,Shlomo Ta'asan +6 more
TL;DR: In this article, the role of energy in texture development is discussed, measured by a character distribution, based on an entropy based theory based on mass transport and a Kantorovich-Rubinstein-Wasserstein metric.
