This paper describes the development of a Spanish-Spanish Sign Language (LSE) translation system. Firstly, it describes the first Spanish-Spanish Sign Language (LSE) parallel corpus focused on two specific domains: the renewal of the Identity Document and Driver's License. This corpus includes more than 4,000 Spanish sentences (in these domains), their LSE(More)
Comparing the metabolic pathways of different species is useful for understanding metabolic functions and can help in studying diseases and engineering drugs. Several comparison techniques for metabolic pathways have been introduced in the literature as a first attempt in this direction. The approaches are based on some simplified representation of(More)
We analyze the linear conductance of a semiconductor quantum wire containing a region where a local Rashba spin-orbit interaction is present. We show that Fano lineshapes appear in the conductance due to the formation of quasi bound states which interfere with the direct transmission along the wire, a mechanism that we term the Fano-Rashba effect. We obtain(More)
Dream quality and sleep paralysis in medical students Abstract Introduction: Sleep paralysis is a conscious state body immobilization event that appears spontaneously or secondarily to stress situations or to possible bad quality of dream. Objective: To determine medical students association and risk of sleep paralysis in bad sleepers. Design: Analytical,(More)
Percepción de la conducta de los padres en los comportamientos antisociales mostrados por los jóvenes participantes de deportes colectivos* A b S t r A c t The main aim of the study was to know the relationships between parents and children with regard to perception of intention, performance and judgment of antisocial behaviors in the sport context,(More)
We investigate nonlinear transport properties of quantum conductors in response to both electrical and thermal driving forces. Within the scattering approach, we determine the nonequilibrium screening potential of a generic mesoscopic system and find that its response is dictated by particle and entropic injectivities which describe the charge and entropy(More)
: We consider fluctuation relations between the transport coefficients of a spintronic system where magnetic interactions play a crucial role. We investigate a prototypical spintronic device - a spin-diode - which consists of an interacting resonant level coupled to two ferromagnetic electrodes. We thereby obtain the cumulant generating function for the(More)
