    Trastornos del desarrollo intelectual en América Latina: un marco para establecer las prioridades políticas de investigación y atención

    No full text
    Art√≠culo de publicaci√≥n ISIAnteriormente agrupados bajo el t√©rmino discapacidad intelectual, constituyen un problema poco estudiado y cuantificado en Am√©rica Latina. Los afectados est√°n ausentes en las pol√≠ticas p√ļblicas y no se benefician de las estrategias gubernamentales de desarrollo social y reducci√≥n de la pobreza. En este art√≠culo se aporta una visi√≥n cr√≠tica de los TDI y se describe una nueva taxonom√≠a. Adem√°s, se propone reconocerlos como problema de salud p√ļblica, promover la profesionalizaci√≥n de la atenci√≥n, y sugerir una agenda de investigaci√≥n y acci√≥n regional. En Am√©rica Latina no hay consenso sobre los criterios diagn√≥sticos de los TDI. Pocos programas de rehabilitaci√≥n cubren una proporci√≥n importante de las personas que los padecen, no se ofrecen servicios basados en la evidencia cient√≠fica y las directrices de atenci√≥n no se han evaluado. Los manuales de diagn√≥stico psiqui√°trico conceden m√°s importancia a la identificaci√≥n de los TDI graves, favorecen su subregistro y clasificaciones err√≥neas. Su estudio no se ha priorizado desde las perspectivas jur√≠dica, de las ciencias sociales y de la salud p√ļblica. Por ello escasean las pruebas cient√≠ficas sobre estos trastornos. Faltan competencias espec√≠ficas y profesionalizaci√≥n para el cuidado de estas personas y es indispensable realizar intervenciones de prevenci√≥n, rehabilitaci√≥n, integraci√≥n comunitaria e inclusi√≥n laboral

    A description is given of the detector system which forms the large angle spectrometer and vertex detector of the EMC (European Muon Collaboration) spectrometer. The apparatus is used in the NA9 experiment which studies the complete hadronic final state from the interaction of high energy muons

    Deep Underground Neutrino Experiment (DUNE), Far Detector Technical Design Report, Volume I Introduction to DUNE

    International audienceThe 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‚ÄĒthese 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's 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

    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. 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 II of this TDR, DUNE Physics, describes the array of identified scientific opportunities and key goals. Crucially, we also report our best current understanding of the capability of DUNE to realize these goals, along with the detailed arguments and investigations on which this understanding is based. This TDR volume documents the scientific basis underlying the conception and design of the LBNF/DUNE experimental configurations. As a result, the description of DUNE's experimental capabilities constitutes the bulk of the document. Key linkages between requirements for successful execution of the physics program and primary specifications of the experimental configurations are drawn and summarized. This document also serves a wider purpose as a statement on the scientific potential of DUNE as a central component within a global program of frontier theoretical and experimental particle physics research. Thus, the presentation also aims to serve as a resource for the particle physics community at large

    Reconstruction of interactions in the ProtoDUNE-SP detector with Pandora

    No full text
    International audienceThe Pandora Software Development Kit and algorithm libraries provide pattern-recognition logic essential to the reconstruction of particle interactions in liquid argon time projection chamber detectors. Pandora is the primary event reconstruction software used at ProtoDUNE-SP, a prototype for the Deep Underground Neutrino Experiment far detector. ProtoDUNE-SP, located at CERN, is exposed to a charged-particle test beam. This paper gives an overview of the Pandora reconstruction algorithms and how they have been tailored for use at ProtoDUNE-SP. In complex events with numerous cosmic-ray and beam background particles, the simulated reconstruction and identification efficiency for triggered test-beam particles is above 80% for the majority of particle type and beam momentum combinations. Specifically, simulated 1 GeV/cc charged pions and protons are correctly reconstructed and identified with efficiencies of 86.1¬Ī0.6\pm0.6% and 84.1¬Ī0.6\pm0.6%, respectively. The efficiencies measured for test-beam data are shown to be within 5% of those predicted by the simulation
