    The Corner Rise Seamount complex is located in a small area of the NAFO Subarea 6 (34º- 37º N, 47º - 53º W). The aim of this paper is to review and present the Spanish fisheries information available in this area between 2005 and March 2007. Results show that Kükenthal peak, in particular and western Corner Rise part in general seem to have more species diversity and more fishing yield than the other Corner Rise parts. The most important species in the catches were Beryx splendens, Aphanopus carbo and polyprion americanus. Beryx splendens catches length range was 27 – 41 cm in 2007. Males were more abundant for sizes less than 33 cm. while females were more abundant for bigger sizes

    Simulation of 3d Ising spin glass model using three replicas: study of Binder cumulants

    Full text link
    We have carried out numerical simulations of the three-dimensional Ising spin glass model with first neighbour Gaussian couplings using three replicas for each sample of couplings. We have paid special attention to the measure of two types of Binder cumulant that can be constructed from the three possible overlaps between the replicas. We obtain new information about the possible phase transition and perform an initial analysis of the ultrametricity issue.Comment: 14 pages and 7 figures, available at http://chimera.roma1.infn.it/index_papers_complex.htm

    Study of the phase transition in the 3d Ising spin glass from out of equilibrium numerical simulations

    Full text link
    Using the decay of the out equilibrium spin-spin correlation function we compute the equilibrium Edward-Anderson order parameter in the three dimensional binary Ising spin glass in the spin glass phase. We have checked that the Edward-Anderson order parameter computed from out of equilibrium numerical simulations follows with good precision the critical law as determined in experiments and in numerical studies at equilibrium. We have also studied the dependence of the order parameter with the lattice size. Finally we present a large time study of the scaling of the off-equilibrium fluctuation-dissipation relations.Comment: 14 pages, 7 Postscript figure

    The earliest evidence of true lambdoid craniosynostosis: the case of “Benjamina”, a Homo heidelbergensis child

    Get PDF
    Background The authors report the morphological and neuroimaging findings of an immature human fossil (Cranium 14) diagnosed with left lambdoid synostosis. Discussion The skull was recovered at the Sima de los Huesos site in Atapuerca (Burgos, Spain). Since the human fossil remains from this site have been dated to a minimum age of 530,000 years, this skull represents the earliest evidence of craniosynostosis occurring in a hominid. A brief historical review of craniosynostosis and cranial deformation is provided

    Griffiths singularities in the two dimensional diluted Ising model

    Full text link
    We study numerically the probability distribution of the Yang-Lee zeroes inside the Griffiths phase for the two dimensional site diluted Ising model and we check that the shape of this distribution is that predicted in previous analytical works. By studying the finite size scaling of the averaged smallest zero at the phase transition we extract, for two values of the dilution, the anomalous dimension, η\eta, which agrees very well with the previous estimated values.Comment: 11 pages and 4 figures, some minor changes in Fig. 4, available at http://chimera.roma1.infn.it/index_papers_complex.htm

    Sumisión tácita, derechos de defensa y competencia judicial internacional en las redes de la cuestión de inconstitucionalidad y de la cuestión prejudicial (Comentario a la STJUE, Sala Quinta, de 11 de septiembre de 2014, Asunto C-112/13, A v B y otros)

    La sentencia comentada interpreta el alcance de la sumisión tácita como criterio de competencia judicial internacional, a la luz del art. 47 de la Carta de Derechos Fundamentales de la Unión Europea, en un supuesto en que la sumisión responde a los actos de un representante judicial nombrado sin que el demandado haya tenido conocimiento del proceso. Asimismo, la sentencia aborda las relaciones entre las normas constitucionales nacionales y el principio de primacía del Derecho comunitario en relación con el control de constitucionalidad de las leyes y el régimen de la cuestión prejudicial.The judgment discussed in this paper deals with the scope of tacit prorogation of jurisdiction in the light of Article 47 of the EU Charter of Fundamental Rights in a case where prorogation is due to acts of a Court-appointed representative and the defendant has not been notified. Moreover, the judgment had to consider the relationship between constitutional rules and the primacy of EU principle in relation with the procedure of constitutional review of legal rules and the regime of preliminary ruling itself

    Violation of the Fluctuation Dissipation Theorem in Finite Dimensional Spin Glasses

    Full text link
    We study the violation of the fluctuation-dissipation theorem in the three and four dimensional Gaussian Ising spin glasses using on and off equilibrium simulations. We have characterized numerically the function X(C) that determine the violation and we have studied its scaling properties. Moreover we have computed the function x(C) which characterize the breaking of the replica symmetry directly from equilibrium simulations. The two functions are numerically equal and in this way we have established that the conjectured connection between the violation of fluctuation dissipation theorem in the off-equilibrium dynamics and the replica symmetry breaking at equilibrium holds for finite dimensional spin glasses. These results point to a spin glass phase with spontaneously broken replica symmetry in finite dimensional spin glasses.Comment: 13 pages, 4 figures, also available at http://chimera.roma1.infn.it/index_papers_complex.htm
