Search for gluino mediated bottom- and top-squark production in multijet final states in pp collisions at 8 TeV

A search for supersymmetry is presented based on events with large missing transverse energy, no isolated electron or muon, and at least three jets with one or more identified as a bottom-quark jet. A simultaneous examination is performed of the numbers of events in exclusive bins of the scalar sum of jet transverse momentum values, missing transverse energy, and bottom-quark jet multiplicity. The sample, corresponding to an integrated luminosity of 19.4fb-1, consists of proton-proton collision data recorded at a center-of-mass energy of 8TeV with the CMS detector at the LHC in 2012. The observed numbers of events are found to be consistent with the standard model expectation, which is evaluated with control samples in data. The results are interpreted in the context of two simplified supersymmetric scenarios in which gluino pair production is followed by the decay of each gluino to an undetected lightest supersymmetric particle and either a bottom or top quark-antiquark pair, characteristic of gluino mediated bottom- or top-squark production. Using the production cross section calculated to next-to-leading-order plus next-to-leading-logarithm accuracy, and in the limit of a massless lightest supersymmetric particle, we exclude gluinos with masses below 1170GeV and 1020GeV for the two scenarios, respectively. © 2013 CERN.

Análise e desempenho de tráfego triple play em redes PLC de baixa tensão

Este trabalho faz uma análise de desempenho de aplicações triple play através da tecnologia Power Line Communication, fazendo uma abordagem direcionada para qualidade de serviço e qualidade de experiência. Apresenta resultados obtidos em cenários residenciais onde o uso desta tecnologia como última milha mostra-se uma solução passível de implementação diante dos testes realizados com transmissões de chamadas VoIP, transmissões de vídeo em alta definição e dados. O conceito de rede doméstica, interligando todos os pontos de uma casa, vem representando um novo rumo na definição de um padrão global, no qual a transmissão de dados por meio da fiação elétrica será uma das tecnologias empregadas e de maior destaque. Também será mostrado o desempenho das métricas avaliadas como jitter, largura de banda, perda de pacotes, PSNR, MOS, VQM, SSIM e suas correlações.

Um Modelo de Inovação Bottom Up: Museu de Favela

This article aims to present, describe and discuss the innovation model of the first territorial open-air museum, designed in a favela in Rio de Janeiro, the Favela Museum (MUF). The concepts of slums, traditional museum and ecomuseums differentials are introduced in order to contextualize the universe MUF is inserted. Moreover, the paper discusses the concept of territorial open-air museum collection and how curatorship takes place this context, as well as the possible forms of interaction with the diversity of individuals served by a museum such as MUF. Furthermore, the role of this new museum typology in society is discussed, entities created by bottom up innovation initiative undertaken by MUF into the new museology of action. It concludes with considerations about the shift of focus on the role played by MUF as agent of social and cultural development.

Primary relapse site pattern in women with triple-negative breast cancer

Despite the remarkable improvements in breast cancer (BC) characterization, accurate prediction of BC clinical behavior is often still difficult to achieve. Some studies have investigated the association between the molecular subtype, namely the basal-like BC and the pattern of relapse, however only few investigated the association between relapse pattern and immunohistochemical defined triple-negative breast cancers (TNBCs). The aim of this study was to evaluate the pattern of relapse in patients with TNBC, namely the primary distant relapse site:One-hundred twenty nine (129) invasive breast carcinomas with follow-up information were classified according to the molecular subtype using immunohistochemistry for ER, PgR and Her2. The association between TNBC and distant relapse primary site was analyzed by logistic regression. Using multivariate logistic regression analysis patients with TNBC displayed only 0.09(95% CI: 0.00-0.74; p = 0.02) the odds of, the non-TNBC patients of developing bone primary relapse. Regarding visceral and lymph-node relapse, no differences between in this cohort were found.Though classically regarded as aggressive tumors, TNBCs rarely development primary relapse in bone when compared to non-TNBC, a clinical relevant fact when investigating a metastasis of an occult or non-sampled primary BC.
