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[...]![]()

Martínez Pabón, María Beatriz ; Arqueros Martínez, Fernando ; Fernández Sánchez, Paloma ; Fonseca, V. | Elsevier Science BV | 1995-03-16Electromagnetic 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[...]![]()

Piquero Sanz, Gemma María ; Mejías Arias, Pedro Miguel ; Martínez Herrero, Rosario | Elsevier Science BV | 1994-04-15Sharpness changes of the spatial profile of a gaussian beam induced by spherically aberrated lenses are investigated in terms of the so-called kurtosis parameter. It is shown both theoretically and experimentally that, after a single aberrated l[...]![]()

We consider a family of local BRS-invariant higher covariant derivative regularizations of SU(N) Chem-Simons theory that do not shift the value of the Chem-Simons parameter k to k + sign(k) c(v) at one loop.![]()

Kami?ski, Robert ; Garcia-Martin, R. ; Grynkiewicz, P. ; Peláez Sagredo, José Ramón | Elsevier Science BV | 2009-01We show how the new precise data on kaon decays together with forward dispersion relations, sum rules and once- and twice-subtracted Roy’s equations allow for a precise determination of the sigma meson pole position. We present a comparison and [...]![]()

In this paper, we deal with a discrete-time multiserver retrial queue with finite population. Firstly, we study the Markov chain at the epochs immediately after slot boundaries making emphasis on the computation of its steady-state distribution.[...]![]()

Classical dimension theory, when applied to preference modeling, is based upon the assumption that linear ordering is the only elemental notion for rationality. In fact, crisp preferences are in some way decomposed into basic criteria, each one [...]![]()

The non-isothermal membrane distillation (MD) separation process is known for about 50 years and very few studies are reported on its economics, energy analysis and costs evaluations. Dispersed and confusing water production costs (WPC) and spec[...]![]()

Enciso, A. ; Finkel Morgenstern, Federico ; González López, Artemio ; Rodríguez González, Miguel Ángel | Elsevier Science BV | 2005-01-06We construct new solvable rational and trigonometric spin models with near-neighbors interactions by an extension of the Dunkl operator formalism. In the trigonometric case we obtain a finite number of energy levels in the center of mass frame, [...]![]()

We consider the minimal low-energy action for gravity up to six derivatives which is renormalizable at the two-loop level modulo higher derivative corrections. Then we study the classical solutions corresponding to the Schwarzschild and the Robe[...]![]()

In this paper we deal with decision-making problems over an unfuzzy set of alternatives. On one hand, we propose the problem of finding a max-min transitive relation as near as possible to a given initial preference relation, under the least-squ[...]![]()

We present an application of the analysis of light propagation in optical waveguides using the dynamic programming technique. We have obtained results for the transit time light pulse propagated in periodically segmented waveguides. Different se[...]![]()

Salcedo Sanz, S. ; Portilla Figueras, J.A. ; Ortiz Garcíaq, E.G. ; Pérez Bellido, A.M. ; García Herrera, Ricardo ; Elorrieta, J.I. | Elsevier Science BV | 2009-11-15This paper discusses the performance of Radial Basis Function networks (RBF) in a problem of spatial regression of pollutants in Madrid. Specifically, the spatial regression of NO_(x) and O_(3) is considered, in such a way that, starting from a [...]![]()

Muñoz, Laura ; Fernández Ramírez, César ; Relaño Pérez, Armando ; Retamosa Granado, Joaquín | Elsevier Science BV | 2012-03-29We present a robust analysis of the spectral fluctuations exhibited by the light meson spectrum. This analysis provides information about the degree of chaos in light mesons and may be useful to get some insight on the underlying interactions. O[...]
