Freire-Lista, D.M ; Fort González, Rafael ; Varas Muriel, María José | Elsevier Science BV | 2016-11San Pedro leucogranite from A Coruña, in the Northwest of Spain, has been a building stone widely used in the Middle Ages. Colour, rarity, appearance and petrophysical properties have led to the use of this leucogranite. Monuments such as church[...]![]()

We make a thermal analysis of the light scalar susceptibilities using SU(3)-chiral perturbation theory to one-loop order, taking into account the QCD source of isospin breaking (IB), i.e. corrections coming from m(u) not equal m(d). The value of[...]![]()

The string equation appearing in the double scaling limit of the Hermitian one–matrix model, which corresponds to a Galilean self–similar condition for the KdV hierarchy, is reformulated as a scaling self–similar condition for the Ur–KdV hierarc[...]![]()

Martínez, S. ; Arqueros Martínez, Fernando ; Fonseca González, Mª Victoria | Elsevier Science BV | 1995-03-15Electromagnetic energy injected into the universe above a few hundred TeV is expected to pile up as ? radiation in a relatively narrow energy interval below 100 TeV due to its interaction with the 2.7^°K background radiation. We present an upper[...]![]()

We present the results of an analysis of data recorded at the Pierre Auger Observatory in which we search for groups of directionally-aligned events (or 'multiplets') which exhibit a correlation between arrival direction and the inverse of the e[...]![]()

Torcal Milla, Francisco José ; Sánchez Brea, Luis Miguel ; Salgado Remacha, Francisco Javier ; Bernabeu Martínez, Eusebio | Elsevier Science BV | 2010-10-15We analyze the near field behavior of binary amplitude gratings which present a curved profile. This configuration has an important application in rotary optical encoders. This kind of encoders is used to measure the angular displacement between[...]![]()

This work is concerned with the following system: [GRAPHICS] which is a model to describe several phenomena in which aggregation plays a crucial role as, for instance, motion of bacteria by chemotaxis and equilibrium of self-attracting clusters.[...]![]()

In this paper we consider aggregation operators satisfying non-decreasingness and some specific boundary conditions. We then analyze some properties of such a family of aggregation operators, introducing the semiautoduality condition, which is w[...]![]()

A variation on the abelian Higgs model, with SU(2)global x U(1)local symmetry broken to U(1)global, was recently shown by Vachaspati and Achucarro to admit stable, finite-energy cosmic string solutions, even though the manifold of minima of the [...]![]()

We construct a model for the quark-gluon vertex of Landau gauge QCD. This is of twofold interest: on the one hand the quark-gluon interaction is at the heart of quark confinement, on the other hand it is a central element in hadron phenomenology[...]![]()

Arroba, Patricia ; Risco Martín, José Luis ; Zapater Sancho, Marina ; Moya, José Manuel ; Ayala Rodrigo, José Luis ; Olcoz Herrero, Katzalin | Elsevier Science BV | 2014As advanced Cloud services are becoming mainstream, the contribution of data centers in the overall power consumption of modern cities is growing dramatically. The average consumption of a single data center is equivalent to the energy consumpti[...]![]()

Carrasco Millán, Pedro ; García-Ferrero, M. Ángeles ; Llanes Estrada, Felipe José ; Porras Riojano, Ana ; Sánchez García, Esteban M. | Elsevier Science BV | 2018-05We deploy Shannon’s information entropy to the distribution of branching fractions in a particle decay. This serves to quantify how important a given new reported decay channel is, from the point of view of the information that it adds to the al[...]
