Search for heavy resonances decaying to two Higgs bosons in final states containing four b quarks

A search is presented for narrow heavy resonances X decaying into pairs of Higgs bosons (H) in proton-proton collisions collected by the CMS experiment at the LHC at root s = 8 TeV. The data correspond to an integrated luminosity of 19.7 fb(-1). The search considers HH resonances with masses between 1 and 3 TeV, having final states of two b quark pairs. Each Higgs boson is produced with large momentum, and the hadronization products of the pair of b quarks can usually be reconstructed as single large jets. The background from multijet and t (t) over bar events is significantly reduced by applying requirements related to the flavor of the jet, its mass, and its substructure. The signal would be identified as a peak on top of the dijet invariant mass spectrum of the remaining background events. No evidence is observed for such a signal. Upper limits obtained at 95 confidence level for the product of the production cross section and branching fraction sigma(gg -> X) B(X -> HH -> b (b) over barb (b) over bar) range from 10 to 1.5 fb for the mass of X from 1.15 to 2.0 TeV, significantly extending previous searches. For a warped extra dimension theory with amass scale Lambda(R) = 1 TeV, the data exclude radion scalar masses between 1.15 and 1.55 TeV

Severe early onset preeclampsia: short and long term clinical, psychosocial and biochemical aspects

Preeclampsia is a pregnancy specific disorder commonly defined as de novo hypertension and proteinuria after 20 weeks gestational age. It occurs in approximately 3-5% of pregnancies and it is still a major cause of both foetal and maternal morbidity and mortality worldwide1. As extensive research has not yet elucidated the aetiology of preeclampsia, there are no rational preventive or therapeutic interventions available. The only rational treatment is delivery, which benefits the mother but is not in the interest of the foetus, if remote from term. Early onset preeclampsia (<32 weeks’ gestational age) occurs in less than 1% of pregnancies. It is, however often associated with maternal morbidity as the risk of progression to severe maternal disease is inversely related with gestational age at onset2. Resulting prematurity is therefore the main cause of neonatal mortality and morbidity in patients with severe preeclampsia3. Although the discussion is ongoing, perinatal survival is suggested to be increased in patients with preterm preeclampsia by expectant, non-interventional management. This temporising treatment option to lengthen pregnancy includes the use of antihypertensive medication to control hypertension, magnesium sulphate to prevent eclampsia and corticosteroids to enhance foetal lung maturity4. With optimal maternal haemodynamic status and reassuring foetal condition this results on average in an extension of 2 weeks. Prolongation of these pregnancies is a great challenge for clinicians to balance between potential maternal risks on one the eve hand and possible foetal benefits on the other. Clinical controversies regarding prolongation of preterm preeclamptic pregnancies still exist – also taking into account that preeclampsia is the leading cause of maternal mortality in the Netherlands5 - a debate which is even more pronounced in very preterm pregnancies with questionable foetal viability6-9. Do maternal risks of prolongation of these very early pregnancies outweigh the chances of neonatal survival? Counselling of women with very early onset preeclampsia not only comprises of knowledge of the outcome of those particular pregnancies, but also knowledge of outcomes of future pregnancies of these women is of major clinical importance. This thesis opens with a review of the literature on identifiable risk factors of preeclampsia

Impacts of the Tropical Pacific/Indian Oceans on the Seasonal Cycle of the West African Monsoon

The current consensus is that drought has developed in the Sahel during the second half of the twentieth century as a result of remote effects of oceanic anomalies amplified by local land–atmosphere interactions. This paper focuses on the impacts of oceanic anomalies upon West African climate and specifically aims to identify those from SST anomalies in the Pacific/Indian Oceans during spring and summer seasons, when they were significant. Idealized sensitivity experiments are performed with four atmospheric general circulation models (AGCMs). The prescribed SST patterns used in the AGCMs are based on the leading mode of covariability between SST anomalies over the Pacific/Indian Oceans and summer rainfall over West Africa. The results show that such oceanic anomalies in the Pacific/Indian Ocean lead to a northward shift of an anomalous dry belt from the Gulf of Guinea to the Sahel as the season advances. In the Sahel, the magnitude of rainfall anomalies is comparable to that obtained by other authors using SST anomalies confined to the proximity of the Atlantic Ocean. The mechanism connecting the Pacific/Indian SST anomalies with West African rainfall has a strong seasonal cycle. In spring (May and June), anomalous subsidence develops over both the Maritime Continent and the equatorial Atlantic in response to the enhanced equatorial heating. Precipitation increases over continental West Africa in association with stronger zonal convergence of moisture. In addition, precipitation decreases over the Gulf of Guinea. During the monsoon peak (July and August), the SST anomalies move westward over the equatorial Pacific and the two regions where subsidence occurred earlier in the seasons merge over West Africa. The monsoon weakens and rainfall decreases over the Sahel, especially in August.Peer reviewe

Measurements of the pp → ZZ production cross section and the Z → 4ℓ branching fraction, and constraints on anomalous triple gauge couplings at √s = 13 TeV

Four-lepton production in proton-proton collisions, pp -> (Z/gamma*)(Z/gamma*) -> 4l, where l = e or mu, is studied at a center-of-mass energy of 13 TeV with the CMS detector at the LHC. The data sample corresponds to an integrated luminosity of 35.9 fb(-1). The ZZ production cross section, sigma(pp -> ZZ) = 17.2 +/- 0.5 (stat) +/- 0.7 (syst) +/- 0.4 (theo) +/- 0.4 (lumi) pb, measured using events with two opposite-sign, same-flavor lepton pairs produced in the mass region 60 4l) = 4.83(-0.22)(+0.23) (stat)(-0.29)(+0.32) (syst) +/- 0.08 (theo) +/- 0.12(lumi) x 10(-6) for events with a four-lepton invariant mass in the range 80 4GeV for all opposite-sign, same-flavor lepton pairs. The results agree with standard model predictions. The invariant mass distribution of the four-lepton system is used to set limits on anomalous ZZZ and ZZ. couplings at 95% confidence level: -0.0012 < f(4)(Z) < 0.0010, -0.0010 < f(5)(Z) < 0.0013, -0.0012 < f(4)(gamma) < 0.0013, -0.0012 < f(5)(gamma) < 0.0013

A inclusão dos estudantes na academia como um desafio à interculturalidade

The capacity of Higher Education Institutions (HEIs) to adopt policies and dynamics that promote interculturality for student inclusion, is a challenge considering the reports, by the participants in this study, of academic exclusion experiences; The aim of this study was to understand the experiences lived in the academy, as inclusion/exclusion phenomena, considering institutional policies and dynamics; Concerning the methods, qualitative, phenomenological-hermeneutic study using phenomenological interviews with thirty one members of the academic community (students, teachers and non-teachers) from a Portuguese HEI, from April to July 2019, supported by qualitative data analysis using Nvivo12. This work is part of a broader project entitled “Inclusive practices in Higher Education: The challenge of building a community”, authorized by the Ethics Committee of the Institution involved. In terms of results, the emerging categories were Experience and meaning of inclusion, with emphasis on “Indiscrimination”, “Equality and equity” and “Integration into the community”; Barriers to inclusion in the institution, with an emphasis on “Architectural Barriers”, “Institutional hierarchical disarticulation” in the adoption of inclusive policies and dynamics and “linguistic difficulties”; and the category Feelings lived in exclusion experiences, with the participants emphasizing “devaluation”, “loneliness” and “sadness”. In conclusion, participants consider that the main institutional challenges to inclusion and interculturality are focused on breaking down architectural and language barriers, so that buildings have adequate access for all types of mobility, guarantee their integration and minimize feelings of devaluation, loneliness, and sadness.A capacidade das Instituições de Ensino Superior (IES) adotarem políticas e dinâmicas promotoras de interculturalidade para a inclusão dos estudantes apresenta-se como um desafio face aos relatos de vivências de exclusão académica dos participantes deste estudo.

Em conclusão, os participantes consideram que os principais desafios institucionais à inclusão e interculturalidade se centram no derrubar as barreiras arquitetónicas e linguísticas, de forma a que os edifícios tenham acessos adequados à mobilidade, que garantam a sua integração e minimizem sentimentos de desvalorização, solidão e tristeza

Tempos, tempos, tempos: Como as escolas organizam os tempos? / Times, times, times: How do schools organize times?

Uma das linhas de pesquisa do nosso Núcleo de Pesquisa tem como pano de fundo o deslocamento do dado do universal da Modernidade para o do múltiplo da Atualidade, através da análise das categorias conhecimento, tempo, espaço e sujeito. Temos aprofundado, nas últimas pesquisas, na temática tempo. Os espaços educacionais estão relacionados a uma certa organização de tempo que, na Modernidade, foi tão bem disseminado para/em nossas escolas. O tempo demarcado nas escolas sofre subordinação e fragmentação cíclica a cada ano através dos anos letivos, níveis/etapas, de ciclos e graus de ensino, com o tempo certo de iniciar e terminar e dentro deste período com seus doze meses, seus bimestres, suas horas/aula. Intentamos falar de um outro tempo, um tempo que está a ser vivido na Atualidade, o agora, o acontecimento e refletir sobre os desdobramentos que isso nos traria para os espaços educacionais. Neste artigo apresentamos o resultado da leitura dos projetos político-pedagógicos de três escolas inovadoras, anotando os indícios dos usos que fazem dos tempos: Escola Amorim Lima, Projeto Âncora, Escola Oga Mitá. Estamos chamando de escolas inovadoras, aquelas que se propõem à construção de uma lógica dos usos dos tempos diferenciada das escolas convencionais nos mecanismos curriculares. A Escola Amorim Lima apresenta um outro modo de fazer e viver a educação escolar, tendo com princípios o respeito e a confiança em cada um dos que habitam o espaçotempo escolar. O Projeto Âncora traz indícios de uma organização escolar que se pergunta sobre sua história, seu passado, seu presente e seu futuro, que se entrelaçam na multiplicidade dos tempos. A Escola Oga Mitá procura inter-relacionar as temporalidades crhónos e aión, adotando como eixo central e transversal o tempo aión

Collaborative research networks as a strategy to synthesize knowledge of Amazonian biodiversity

The Amazon region is critical for maintaining global biodiversity and mitigating climate change; however, it faces escalating threats from deforestation and habitat degradation. Addressing these threats requires evidence-based strategies grounded in investments in science, technology, innovation and collaborative research. The Brazilian National Institute of Science and Technology (INCT) programme plays a central role in advancing scientific and technological progress by establishing collaborative research networks across diverse fields and regions. In this context, we present the INCT in Synthesis of Amazonian Biodiversity (INCT-SynBiAm) as a case study, illustrating how research networks can promote diversity in academia and enhance our understanding of biodiversity in hyperdiverse tropical regions. The SynBiAm network integrates 47 academic and non-academic institutions from Brazil and abroad. Its key objectives are to establish and expand a collaborative initiative for research synthesis in Amazonia, deepen our understanding of biodiversity patterns, threats and drivers in forest and freshwater ecosystems, inform environmental and educational practices and policies, and train future educators, decision-makers and scientists committed to the Amazon’s conservation and sustainability. We outline the INCT programme and demonstrate how the INCT-SynBiAm network can achieve these goals, providing a model for future collaborative initiatives aimed at addressing socio-ecological challenges in tropical regions
