Contact projective structures and chains math.DG Contact projective structures have been profoundly studied by D.J.F. Fox. He associated to a contact projective structure a canonical projective structure on the same manifold. We interpret Fox' construction in terms of the equivalent parabolic (Cartan) geometries, s...

NNLO corrections to B --> X_u l nu and the determination of |V_ub| hep-ph The calculation of partial decay rates in B --> X_u l nu decays at next-to-next-to-leading order (NNLO) in alpha_s and to leading order in 1/m_b is described. New results for the hard function are combined with known results for the jet funct...

$k^*$-Metrizable Spaces and their Applications math.GN In this paper we introduce and study so-called $k^*$-metrizable spaces forming a new class of generalized metric spaces, and display various applications of such spaces in topological algebra, functional analysis, and measure theory. By definition, a Hausdorf...

Asymptotic normality for deconvolution kernel density estimators from random fields math.ST stat.TH The paper discusses the estimation of a continuous density function of the target random field $X_{\bf{i}}$, $\bf{i}\in \mathbb {Z}^N$ which is contaminated by measurement errors. In particular, the observed random...

The evolution of a pre-heated Intergalactic Medium astro-ph We analyse the evolution of the Intergalactic Medium (IGM) by means of an extended set of large box size hydrodynamical simulations which include pre-heating. We focus on the properties of the z~2 Lyman-alpha forest and on the population of clusters and gr...

Macrospin model of incubation delay due to the field-like spin transfer torque cond-mat.mes-hall We show that the absence of pre-switching oscillations ("incubation delay") in magnetic tunnel junctions can be explained within the macrospin model by a sizable field-like component of the spin-transfer torque. It is...
