Sánchez Brea, Luis Miguel ; Alonso Fernández, José ; Bernabeu Martínez, Eusebio | Elsevier Science BV | 2004-06-01When a polychromatic light illuminates a grating, an achromatic and continuous self-imaging regime is produced, what means that Talbot planes are eliminated. In this work, we investigate the existence of this continuous regime for generalized gr[...]![]()

In this paper we study properties ofcertain fuzzy maps associated to a map, and we apply these properties to obtain results on quotient fuzzy topological spaces.![]()

Gonzalo, A. ; Nogales Díaz, Emilio ; Lorenz, K. ; Víllora, E. G. ; Shimamura, K: ; Piqueras de Noriega, Javier ; Méndez Martín, Bianchi | Elsevier Science BV | 2017-11The structural and luminescence properties of gallium oxide nanowires doped with chromium or manganese have been investigated. Undoped Ga?O? nanostructures have been fabricated by a thermal evaporation method, while doping was subsequently achie[...]![]()

This paper deals with the aggregation of individual fuzzy preference relations. The idea behind a democratic fuzzy aggregation rule is in the first place related to the concepts of individual power and social consensus, and it is pointed out tha[...]![]()

We report on recent progress on the chiral unitary approach, analogous to the effective range expansion in Quantum Mechanics, which is shown to have a much larger convergence radius than ordinary chiral perturbation theory, allowing one to repro[...]![]()

We introduce in this paper an iterative estimation procedure based on conditional medians valid to fit linear models when, on the one hand, the distribution of errors, assumed to be known, may be general and, on the other, the dependent data ste[...]![]()

A relativistic many-body calculation for an effective QCD Hamiltonians reported for exotic and charmed hybrid mesons. The nonexotic J(PC) = 1(--) charmonium spectrum now resolves the anonymous overpopulation of observed J/psi states. The exotic [...]![]()

We represent QCD at the hadronic scale by means of an effective Hamiltonian, H, formulated in the Coulomb gauge. As in the Nambu-Jona-Lasinio model, chiral symmetry is explicitly broken, however our approach is renormalizable and also includes c[...]![]()

Morcuende, D. ; Rosado, J. ; Contreras González, José Luis ; Arqueros Martínez, Fernando | Elsevier Science BV | 2019-01Atmospheric fluorescence is usually neglected in the reconstruction of the signals registered by Cherenkov telescopes, both IACTs and wide-angle detector arrays. In this paper we quantify the fluorescence contribution to the total light recorded[...]![]()

We discuss in general terms pole trajectories of resonances coupling to a continuum channel as some strength parameter is varied. It is demonstrated that, regardless of the underlying dynamics, the trajectories of poles that couple to the contin[...]![]()

Blázquez Salcedo, José Luis ; Kunz, Jutta ; Navarro Lérida, Francisco ; Radu, Eugen | Elsevier Science BV | 2017-08-10We construct a generalization of the AdS charged rotating black holes with two equal magnitude angular momenta in five-dimensional minimal gauged supergravity. In addition to the mass, electric charge and angular momentum, the new solutions poss[...]![]()

In the double rank analysis of research publications, the local rank position of a country or institution publication is expressed as a function of the world rank position. Excluding some highly or lowly cited publications, the double rank plot [...]![]()

By means of a coupled channel non-perturbative unitary approach, it is possible to extend the strong constrains of Chiral Perturbation Theory to higher energies. In particular, it is possible to reproduce the lowest lying resonances in meson-mes[...]![]()

Direct (oxidation) methanol fuel cells (DMFCs) are attractive for several applications, however, there are several barriers which must be overcome before they can become an alternative to internal combustion engines. At present, methanol crossov[...]![]()

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[...]![]()
