    El importante papel que juegan las emociones en los contextos deportivos ha sido ampliamente defendido en la literatura sobre psicología del deporte. El objetivo de este estudio es desarrollar y validar un instrumento para evaluar la competencia emocional de los deportistas. La muestra la componen 367 deportistas de ambos géneros pertenecientes a diferentes disciplinas deportivas. Se analizaron los antecedentes y las características psicométricas de la Escala de Desarrollo Emocional (Schutte, Malouff, Hall, Haggerty, Cooper, Golden y Dornhein, 1998). Los resultados obtenidos confirmaron en términos generales el modelo de cuatro factores propuesto por los autores originales y además, plantea la posibilidad de incluir mejoras sustanciales del cuestionario para futuras versiones relacionadas con su aplicabilidad.The relevant role of emotions in competitive contexts has been widely supported in the sport psychology literature. The aim of this study was to create a valid measure of emotional development in sports. The sample is composed by 367 sportsmen/women belonging to different sporting disciplines. Analyses were performed about the antecedents and the psychometric properties of the Emotional Development Scale (Schutte, Malouff, Hall, Haggerty, Cooper, Golden & Dornhein, 1998). Results showed that, in general terms, the initially proposed four factor model was supported. Implications for considering the improvement of the applicability questionnaire are advance

    Objective To evaluate the responsiveness in terms of correlation of the Hospital Universitario La Princesa Index (HUPI) comparatively to the traditional composite indices used to assess disease activity in rheumatoid arthritis (RA), and to compare the performance of HUPI-based response criteria with that of the EULAR response criteria. Methods Secondary data analysis from the following studies: ACT-RAY (clinical trial), PROAR (early RA cohort) and EMECAR (pre-biologic era long term RA cohort). Responsiveness was evaluated by: 1) comparing change from baseline (Delta) of HUPI with Delta in other scores by calculating correlation coefficients; 2) calculating standardised effect sizes. The accuracy of response by HUPI and by EULAR criteria was analyzed using linear regressions in which the dependent variable was change in global assessment by physician (Delta GDA-Phy). Results Delta HUPI correlation with change in all other indices ranged from 0.387 to 0.791); HUPI's standardized effect size was larger than those from the other indices in each database used. In ACT-RAY, depending on visit, between 65 and 80% of patients were equally classified by HUPI and EULAR response criteria. However, HUPI criteria were slightly more stringent, with higher percentage of patients classified as non-responder, especially at early visits. HUPI response criteria showed a slightly higher accuracy than EULAR response criteria when using Delta GDA-Phy as gold standard. Conclusion HUPI shows good responsiveness in terms of correlation in each studied scenario (clinical trial, early RA cohort, and established RA cohort). Response criteria by HUPI seem more stringent than EULAR''s

    Volume I. Introduction to DUNE

    The preponderance of matter over antimatter in the early universe, the dynamics of the supernovae that produced the heavy elements necessary for life, and whether protons eventually decay—these mysteries at the forefront of particle physics and astrophysics are key to understanding the early evolution of our universe, its current state, and its eventual fate. The Deep Underground Neutrino Experiment (DUNE) is an international world-class experiment dedicated to addressing these questions as it searches for leptonic charge-parity symmetry violation, stands ready to capture supernova neutrino bursts, and seeks to observe nucleon decay as a signature of a grand unified theory underlying the standard model. The DUNE far detector technical design report (TDR) describes the DUNE physics program and the technical designs of the single- and dual-phase DUNE liquid argon TPC far detector modules. This TDR is intended to justify the technical choices for the far detector that flow down from the high-level physics goals through requirements at all levels of the Project. Volume I contains an executive summary that introduces the DUNE science program, the far detector and the strategy for its modular designs, and the organization and management of the Project. The remainder of Volume I provides more detail on the science program that drives the choice of detector technologies and on the technologies themselves. It also introduces the designs for the DUNE near detector and the DUNE computing model, for which DUNE is planning design reports. Volume II of this TDR describes DUNE\u27s physics program in detail. Volume III describes the technical coordination required for the far detector design, construction, installation, and integration, and its organizational structure. Volume IV describes the single-phase far detector technology. A planned Volume V will describe the dual-phase technology

    Highly-parallelized simulation of a pixelated LArTPC on a GPU

    Get PDF
    The rapid development of general-purpose computing on graphics processing units (GPGPU) is allowing the implementation of highly-parallelized Monte Carlo simulation chains for particle physics experiments. This technique is particularly suitable for the simulation of a pixelated charge readout for time projection chambers, given the large number of channels that this technology employs. Here we present the first implementation of a full microphysical simulator of a liquid argon time projection chamber (LArTPC) equipped with light readout and pixelated charge readout, developed for the DUNE Near Detector. The software is implemented with an end-to-end set of GPU-optimized algorithms. The algorithms have been written in Python and translated into CUDA kernels using Numba, a just-in-time compiler for a subset of Python and NumPy instructions. The GPU implementation achieves a speed up of four orders of magnitude compared with the equivalent CPU version. The simulation of the current induced on 10^3 pixels takes around 1 ms on the GPU, compared with approximately 10 s on the CPU. The results of the simulation are compared against data from a pixel-readout LArTPC prototype

    The preponderance of matter over antimatter in the early universe, the dynamics of the supernovae that produced the heavy elements necessary for life, and whether protons eventually decay—these mysteries at the forefront of particle physics and astrophysics are key to understanding the early evolution of our universe, its current state, and its eventual fate. The Deep Underground Neutrino Experiment (DUNE) is an international world-class experiment dedicated to addressing these questions as it searches for leptonic charge-parity symmetry violation, stands ready to capture supernova neutrino bursts, and seeks to observe nucleon decay as a signature of a grand unified theory underlying the standard model. The DUNE far detector technical design report (TDR) describes the DUNE physics program and the technical designs of the single- and dual-phase DUNE liquid argon TPC far detector modules. Volume III of this TDR describes how the activities required to design, construct, fabricate, install, and commission the DUNE far detector modules are organized and managed. This volume details the organizational structures that will carry out and/or oversee the planned far detector activities safely, successfully, on time, and on budget. It presents overviews of the facilities, supporting infrastructure, and detectors for context, and it outlines the project-related functions and methodologies used by the DUNE technical coordination organization, focusing on the areas of integration engineering, technical reviews, quality assurance and control, and safety oversight. Because of its more advanced stage of development, functional examples presented in this volume focus primarily on the single-phase (SP) detector module

    Torsión lobar pulmonar espontánea en un canino mestizo y posterior desarrollo de una neoplasia ósea apendicular: reporte de caso

    No full text
    En este reporte se describe el caso de un canino mestizo hembra de ocho años de edad, que presentaba historia de diez días de letargia, anorexia, pérdida de peso, vómito ocasional, tos esporádica y dificultad respiratoria; los hallazgos clínicos, radiográficos y ultrasonográficos sugirieron como diagnóstico diferencial más probable torsión lobar pulmonar del lóbulo medio derecho y éste se confirmó mediante toracotomía exploratoria; el manejo terapéutico incluyó resección del lóbulo afectado; no se identificó ninguna etiología subyacente. La paciente tuvo una recuperación completa de la torsión lobar; sin embargo, dos semanas después de la cirugía presentó claudicación severa del miembro anterior derecho y se encontraron hallazgos radiográficos compatibles con neoplasia ósea en la epífisis proximal del húmero; por decisión de los propietarios sólo se realizó manejo analgésico y un mes después se practicó eutanasia debido a una posible metástasis pulmonar; es posible que la neoplasia y posible metástasis se tratasen de eventos concomitantes sin relación causa-efecto; sin embargo, pudo haber existido una asociación entre un proceso estresante y traumático (la torsión pulmonar) con el desarrollo y manifestación de una patología oncológica subyacente
