    Wilson's disease consists in a inborn error of metabolism with marked neuropsychiatric manifestations. These manifestations need to be correctly identified and treated. There are four neuropsychiatric symptoms clusters established for Wilson's disease patients: behavior and/or personality disorders, mood disorders, cognitive deficits, and psychotic manifestations. Although such patients are more commonly seen in neurological and hepatological settings, mental health professionals must keep in mind a high level of suspicion, once first presentations may be of psychiatric nature. This study presents a review of literature about neuropsychiatric aspects of Wilson's disease, emphasizing diagnostic issues. It is presented the case of a 26 years old male patient initially with psychiatric polimorfic symptoms. The treatment of this patient with electroconvulsive therapy is presented, adding a report of this therapeutic modality, applied to that case, to the two only previous records in the literature.A doença de Wilson (DW) é condição sistêmica decorrente de erro inato do metabolismo, com importantes manifestações neuropsiquiátricas. Estas requerem identificação diagnóstica adequada e intervenções terapêuticas eficazes. Existem, estabelecidos, quatro clusters de sintomas neuropsiquiátricos na DW: distúrbios de comportamento e/ou personalidade, distúrbios do humor, déficit cognitivo e quadros psicóticos. Embora tais pacientes sejam vistos, mais comumente, em clínicas neurológicas e de hepatologia, os profissionais de saúde mental devem manter alto nível de suspeição para DW, já que os quadros iniciais podem se manifestar como síndromes psiquiátricas. Neste artigo é apresentada uma revisão da literatura sobre os aspectos neuropsiquiátricos da doença de Wilson, enfatizando-se as dificuldades diagnósticas. Um homem de 26 de idade DW com apresentação psiquiátrica inicial polimórfica é apresentado. O tratamento deste paciente com a eletroconvulsoterapia é relatado, somando-se esta forma de intervenção terapêutica, neste caso, aos dois únicos existentes na literatura87688

    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

    Snowmass Neutrino Frontier: DUNE Physics Summary

    No full text
    The Deep Underground Neutrino Experiment (DUNE) is a next-generation long-baseline neutrino oscillation experiment with a primary physics goal of observing neutrino and antineutrino oscillation patterns to precisely measure the parameters governing long-baseline neutrino oscillation in a single experiment, and to test the three-flavor paradigm. DUNE's design has been developed by a large, international collaboration of scientists and engineers to have unique capability to measure neutrino oscillation as a function of energy in a broadband beam, to resolve degeneracy among oscillation parameters, and to control systematic uncertainty using the exquisite imaging capability of massive LArTPC far detector modules and an argon-based near detector. DUNE's neutrino oscillation measurements will unambiguously resolve the neutrino mass ordering and provide the sensitivity to discover CP violation in neutrinos for a wide range of possible values of δCP\delta_{CP}. DUNE is also uniquely sensitive to electron neutrinos from a galactic supernova burst, and to a broad range of physics beyond the Standard Model (BSM), including nucleon decays. DUNE is anticipated to begin collecting physics data with Phase I, an initial experiment configuration consisting of two far detector modules and a minimal suite of near detector components, with a 1.2 MW proton beam. To realize its extensive, world-leading physics potential requires the full scope of DUNE be completed in Phase II. The three Phase II upgrades are all necessary to achieve DUNE's physics goals: (1) addition of far detector modules three and four for a total FD fiducial mass of at least 40 kt, (2) upgrade of the proton beam power from 1.2 MW to 2.4 MW, and (3) replacement of the near detector's temporary muon spectrometer with a magnetized, high-pressure gaseous argon TPC and calorimeter
