    Introdução: Os impactos da afasia vão além de alterações de linguagem ou comunicação, afetando a qualidade de vida e a participação social. Faz-se necessário, portanto, que o fonoaudiólogo atue de forma interdisciplinar e amplie seu escopo de atuação na terapia das afasias, indo além de uma perspectiva que foca majoritariamente na correção de déficits linguísticos. Esta comunicação discute a importância de metas de incentivo à inclusão social e aponta caminhos para melhor atender às demandas dessa população. Objetivo: Discutir o trabalho do fonoaudiólogo no que tange a metas de enfrentamento dos impactos sociais da afasia. Método: Revisão não sistemática de literatura. São discutidos temas ligados à inclusão social e apresentadas iniciativas nacionais que promovem a participação social da pessoa com afasia. Resultados: Apesar das lacunas ainda existentes, as ações crescentes de diversos grupos de convivência, a criação de associações e as campanhas de conscientização da população apontam para importantes sinais de mudança no escopo de atuação do fonoaudiólogo junto a essa população. Conclusão: Há um crescimento das intervenções em grupo e valorização de atividades artísticas oferecidas junto a pessoas que vivem com afasia. Os estudos sobre tais intervenções demonstram impactos positivos na qualidade de vida, participação social e funcionalidade da comunicação dessa população. São necessários esforços no sentido de trabalhar com a família e com a sociedade, bem como ampliar políticas públicas e oferecer serviços que promovam a inclusão social da pessoa com afasia.Introduction: The impacts of aphasia are not restricted to changes in language or communication, and affect both quality of life and social participation. Therefore, it is essential that speech-language pathologists work within an interdisciplinary approach and their scope of action in aphasia therapy should not be restricted to correct language deficits. This study discusses the importance of social inclusion goals in aphasia therapy, suggesting ways to better meet the demands of this population. Objective: To discuss the role of speech-language pathologists in tackling the social impacts of aphasia. Method: This is a non systematic literature review that addresses topics related to social inclusion, as well as current Brazilian initiatives that promote social participation for people with aphasia. Results: Despite remaining gaps, there are important signs of a change in perspective and scope of action of speech-language pathologists, such as increasing actions involving peer groups, the development of associations, as well as nation-wide awareness campaigns. Conclusion: There has been an increase in group interventions, as well as greater promotion of artistic activities for people with aphasia. Studies on these interventions report positive impacts on quality of life, social participation and functional communication for this population. Further combined efforts with family members and society as a whole are needed, as well as the promotion of policies and services that promote social inclusion for people with aphasia.Introducción: los impactos de la afasia van más allá que las alteraciones de lenguaje o de comunicación, afectando la calidad de vida y la participación social.

    A search for heavy resonances decaying into a Higgs boson (HH) and a new particle (XX) is reported, utilizing 36.1 fb1^{-1} of proton-proton collision data at s=\sqrt{s} = 13 TeV collected during 2015 and 2016 with the ATLAS detector at the CERN Large Hadron Collider. The particle XX is assumed to decay to a pair of light quarks, and the fully hadronic final state XHqqˉbbˉXH \rightarrow q\bar q'b\bar b is analysed. The search considers the regime of high XHXH resonance masses, where the XX and HH bosons are both highly Lorentz-boosted and are each reconstructed using a single jet with large radius parameter. A two-dimensional phase space of XHXH mass versus XX mass is scanned for evidence of a signal, over a range of XHXH resonance mass values between 1 TeV and 4 TeV, and for XX particles with masses from 50 GeV to 1000 GeV. All search results are consistent with the expectations for the background due to Standard Model processes, and 95% CL upper limits are set, as a function of XHXH and XX masses, on the production cross-section of the XHqqˉbbˉXH\rightarrow q\bar q'b\bar b resonance

    Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

    A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements

    Combined searches for the production of supersymmetric top quark partners in proton-proton collisions at root s=13 TeV

    A combination of searches for top squark pair production using proton-proton collision data at a center-of-mass energy of 13 TeV at the CERN LHC, corresponding to an integrated luminosity of 137 fb(-1) collected by the CMS experiment, is presented. Signatures with at least 2 jets and large missing transverse momentum are categorized into events with 0, 1, or 2 leptons. New results for regions of parameter space where the kinematical properties of top squark pair production and top quark pair production are very similar are presented. Depending on themodel, the combined result excludes a top squarkmass up to 1325 GeV for amassless neutralino, and a neutralinomass up to 700 GeV for a top squarkmass of 1150 GeV. Top squarks with masses from 145 to 295 GeV, for neutralino masses from 0 to 100 GeV, with a mass difference between the top squark and the neutralino in a window of 30 GeV around the mass of the top quark, are excluded for the first time with CMS data. The results of theses searches are also interpreted in an alternative signal model of dark matter production via a spin-0 mediator in association with a top quark pair. Upper limits are set on the cross section for mediator particle masses of up to 420 GeV

    Search for new particles in events with energetic jets and large missing transverse momentum in proton-proton collisions at root s=13 TeV

    A search is presented for new particles produced at the LHC in proton-proton collisions at root s = 13 TeV, using events with energetic jets and large missing transverse momentum. The analysis is based on a data sample corresponding to an integrated luminosity of 101 fb(-1), collected in 2017-2018 with the CMS detector. Machine learning techniques are used to define separate categories for events with narrow jets from initial-state radiation and events with large-radius jets consistent with a hadronic decay of a W or Z boson. A statistical combination is made with an earlier search based on a data sample of 36 fb(-1), collected in 2016. No significant excess of events is observed with respect to the standard model background expectation determined from control samples in data. The results are interpreted in terms of limits on the branching fraction of an invisible decay of the Higgs boson, as well as constraints on simplified models of dark matter, on first-generation scalar leptoquarks decaying to quarks and neutrinos, and on models with large extra dimensions. Several of the new limits, specifically for spin-1 dark matter mediators, pseudoscalar mediators, colored mediators, and leptoquarks, are the most restrictive to date.Peer reviewe

    Measurement of the top quark mass using events with a single reconstructed top quark in pp collisions at root s=13 TeV

    Abstract:A measurement of the top quark mass is performed using a data sample en-riched with single top quark events produced in thetchannel. The study is based on proton-proton collision data, corresponding to an integrated luminosity of 35.9 fb−1, recorded at√s= 13TeV by the CMS experiment at the LHC in 2016. Candidate events are selectedby requiring an isolated high-momentum lepton (muon or electron) and exactly two jets,of which one is identified as originating from a bottom quark. Multivariate discriminantsare designed to separate the signal from the background. Optimized thresholds are placedon the discriminant outputs to obtain an event sample with high signal purity. The topquark mass is found to be172.13+0.76−0.77GeV, where the uncertainty includes both the sta-tistical and systematic components, reaching sub-GeV precision for the first time in thisevent topology. The masses of the top quark and antiquark are also determined separatelyusing the lepton charge in the final state, from which the mass ratio and difference aredetermined to be0.9952+0.0079−0.0104and0.83+1.79−1.35GeV, respectively. The results are consistentwithCPTinvariance

    The first measurements of diboson production cross sections in proton-proton interactions at a center-of-mass energy of 5.02 TeV are reported. They are based on data collected with the CMS detector at the LHC, corresponding to an integrated luminosity of 302 pb(-1). Events with two, three, or four charged light leptons (electrons or muons) in the final state are analyzed. The WW, WZ, and ZZ total cross sections are measured as sigma(WW) = 37:0(-5.2)(+5.5) (stat)(-2.6)(+2.7) (syst) pb, sigma(WZ) = 6.4(-2.1)(+2.5) (stat)(-0.3)(+0.5)(syst) pb, and sigma(ZZ) = 5.3(-2.1)(+2.5)(stat)(-0.4)(+0.5) (syst) pb. All measurements are in good agreement with theoretical calculations at combined next-to-next-to-leading order quantum chromodynamics and next-to-leading order electroweak accuracy
