    Although judo is a sport with great tradition that is practised worldwide, the state of the art and scientific advanc- es have not been analysed from a bibliometric point of view up to now. The aim of the present article is the status of the scientific production, collaboration, and impact of scientific pa- pers on judo, as well as the most active research groups working on this topic. Our analysis was based on documents retrieved from the Science Citation Index and Social Science Citation Index. Bibliometric analysis and network construction were performed using Histcite and Bibexcel software. As a result, 383 original papers and scientific reviews were retrieved from 162 journals in 78 Web of Science® cate- gories. Archives of Budo had the highest number of articles (56), and International Journal of Sports Medicine had the highest number of citations (192). More than half of the articles were within the area of sports science. The co- authorship network (threshold ≥3 articles) enabled us to identify 6 clusters of authors written in partnership. The citation network was formed mainly by 14 authors. Although research on judo is still at an early stage and has a lower profile than other sports, its development has potential interest to many scientific fields and sports in general. Judo research is mainly published in journals cov- ering sport science and sport medicine topics; the latter being the most cited ones. The co-authorship networks tended to be centralized, with a single lead author, while citation networks between authors were usually directed towards other areas of research.Peset Mancebo, MF.; Ferrer Sapena, A.; Villamón Herrera, M.; González Moreno, LM.; Toca Herrera, J.; Aleixandre Benavent, R.

    Optical characterization of ALD-coated nanoporous alumina structures: effect of sample geometry or coated layer material

    Optical characterization of nanoporous alumina-based structures (NPA-bSs), obtained by ALD deposition of a thin conformal SiO2 layer on two alumina nanosupports with different geometrical parameters (pore size and interpore distance), was performed by two noninvasive and nondestructive techniques such as spectroscopic ellipsometry (SE) and photoluminescence (Ph) spectra. SE measurements allow us to estimate the refraction index and extinction coefficient for the studied samples and their dependence with wavelength for the 250–1700 nm interval, showing the effect of sample geometry and cover-layer material (SiO2, TiO2, or Fe2O3), which significantly affect the oscillatory character of both parameters, as well as changes associated with the light incidence angle, which are attributed to surface impurities and inhomogeneity. Photoluminescence curves exhibit a similar shape independently of sample pore-size/porosity, but they seem to affect intensity values. This analysis shows the potential application of these NPA-bSs platforms to nanophotonics, optical sensing, or biosensing.Partial funding for open access charge: Universidad de Málag

    An efficient strategy for modeling the human auditory system from Micro-Computed Tomography Imaging.

    Finite Element modeling is a widely used methodology to build numerical models and simulate the behavior of the human auditory system; this has allowed essential advances in understanding the biomechanics of that complex system. There are two key points in modeling: the construction of an adequate geometry that allows efficient meshing and the correct use of mechanical properties of the materials. This research aims to show a new strategy for automating the build Finite Element Model process of the human auditory system using the FEM from Micro-Computed Tomography (Micro-CT) Imaging. The idea behind this methodology is to build a Finite Element Model with a computational and temporal low cost. This work allowed us to design the first semi-automatic algorithm to build a finite element model of the human middle ear that will later be used to incorporate the other components of the auditory system for different types of studies.Universidad de Málaga.

    La atenuación en los verbos que expresan duda presentes en conversaciones coloquiales del proyecto AMERESCO de Santiago de Chile

    Get PDF
    En este trabajo se indaga en el comportamiento de la atenuación en los verbos que expresan duda, presentes en el corpus AMERESCO de conversaciones coloquiales de Santiago de Chile. Se describen las funciones de la atenuación de estos verbos de acuerdo con (1) el tipo de acto de habla, (2) la actividad de imagen y (3) algunas características sintáctico-discursivas. Los principales hallazgos demuestran que la atenuación se manifiesta a través de verbos doxásticos (creer, parecer, cachar, etc.), verbos modales (poder, deber) y el verbo “saber” con polaridad negativa (“no sé”). Esta surge cuando se presenta lo dicho como una duda, bien para suavizar una opinión contraria o crítica, en cuyo caso su significado es de opinión, bien para informar sobre un estado de cosas, cuando su significado es epistémico. En el reconocimiento de su carácter atenuante, resultan clave el tipo de acto de habla en el que ocurren, el rol proyectado por el hablante en la conversación, la gestión de las imágenes y sus características sintáctico-discursivas, elementos que determinan si estas construcciones verbales expresan mayor o menor atenuación

    Estudio estratigráfico y constructivo del pozo de San Marcial: arqueología y arquitecturas del agua en un asentamiento de conquista bajomedieval (San Marcial de Rubicón, Yaiza, Lanzarote)

    The expedition led by Gadifer de la Salle and Jean de Bethencourt, under the auspices of the Castilian monarch Henry III, arrived on the coast of the island of Lanzarote, officially inaugurating the process of the seigniorial conquest of the Canary archipelago in 1402. The site of San Marcial de Rubicón contains the remains of the first permanent settlement of this European host, including the well of San Marcial de Rubicón, the subject of this paper. This is the first time that a constructive and stratigraphic study of this building has been undertaken, which has allowed us to conclude that its construction responded to a project conceived in advance and executed with professional criteria by the stonemasons who accompanied De la Salle and Bethencourt in that enterprise.La expedición comandada por Gadifer de la Salle y Jean de Bethencourt, auspiciada por el monarca castellano Enrique III, arribó a la costa de la isla de Lanzarote e inauguró con ello de manera oficial el proceso de conquista señorial del archipiélago canario en 1402. El yacimiento de San Marcial de Rubicón acoge los vestigios del primer asentamiento permanente de esta hueste europea, entre los que se encuentra el pozo de San Marcial de Rubicón, objeto de este trabajo. En estas páginas, se aborda por primera vez el estudio constructivo y estratigráfico de esta fábrica, el cual nos ha permitido concluir que su edificación respondió a un proyecto concebido de antemano y ejecutado con criterios profesionales por los canteros que acompañaron a De la Salle y Bethencourt en aquella empresa

    Measurement of the top quark forward-backward production asymmetry and the anomalous chromoelectric and chromomagnetic moments in pp collisions at √s = 13 TeV

    Get PDF
    Abstract The parton-level top quark (t) forward-backward asymmetry and the anomalous chromoelectric (d̂ t) and chromomagnetic (μ̂ t) moments have been measured using LHC pp collisions at a center-of-mass energy of 13 TeV, collected in the CMS detector in a data sample corresponding to an integrated luminosity of 35.9 fb−1. The linearized variable AFB(1) is used to approximate the asymmetry. Candidate t t ¯ events decaying to a muon or electron and jets in final states with low and high Lorentz boosts are selected and reconstructed using a fit of the kinematic distributions of the decay products to those expected for t t ¯ final states. The values found for the parameters are AFB(1)=0.048−0.087+0.095(stat)−0.029+0.020(syst),μ̂t=−0.024−0.009+0.013(stat)−0.011+0.016(syst), and a limit is placed on the magnitude of | d̂ t| < 0.03 at 95% confidence level.

    Search for Physics beyond the Standard Model in Events with Overlapping Photons and Jets

    Get PDF
    Results are reported from a search for new particles that decay into a photon and two gluons, in events with jets. Novel jet substructure techniques are developed that allow photons to be identified in an environment densely populated with hadrons. The analyzed proton-proton collision data were collected by the CMS experiment at the LHC, in 2016 at root s = 13 TeV, and correspond to an integrated luminosity of 35.9 fb(-1). The spectra of total transverse hadronic energy of candidate events are examined for deviations from the standard model predictions. No statistically significant excess is observed over the expected background. The first cross section limits on new physics processes resulting in such events are set. The results are interpreted as upper limits on the rate of gluino pair production, utilizing a simplified stealth supersymmetry model. The excluded gluino masses extend up to 1.7 TeV, for a neutralino mass of 200 GeV and exceed previous mass constraints set by analyses targeting events with isolated photons.Peer reviewe
