Kinetic energy sum spectra in nonmesonic weak decay of hypernuclei

We evaluate the coincidence spectra in the nonmesonic weak decay (NMWD) \Lambda N\go nN of $\Lambda$ hypernuclei $^{4}_\Lambda$He, $^{5}_\Lambda$He, $^{12}_\Lambda$C, $^{16}_\Lambda$O, and $^{28}_\Lambda$Si, as a function of the sum of kinetic energies $E_{nN}=E_n+E_N$ for $N=n,p$. The strangeness-changing transition potential is described by the one-meson-exchange model, with commonly used parameterization. Two versions of the Independent-Particle Shell Model (IPSM) are employed to account for the nuclear structure of the final residual nuclei. They are: (a) IPSM-a, where no correlation, except for the Pauli principle, is taken into account, and (b) IPSM-b, where the highly excited hole states are considered to be quasi-stationary and are described by Breit-Wigner distributions, whose widths are estimated from the experimental data. All $np$ and $nn$ spectra exhibit a series of peaks in the energy interval 110 MeV $<E_{nN}<170$ MeV, one for each occupied shell-model state. The IPSM-a could be a pretty fair approximation for the light $^{4}_\Lambda$He and $^{5}_\Lambda$He hypernuclei. For the remaining, heavier, hypernuclei it is very important, however, to take into account the spreading in strength of the deep-hole states, and bring into play the IPSM-b approach. Notwithstanding the nuclear model that is employed the results depend only very weakly on the details of the dynamics involved in the decay process proper. We propose that the IPSM is the appropriate lowest-order approximation for the theoretical calculations of the of kinetic energy sum spectra in the NMWD. It is in comparison to this picture that one should appraise the effects of the final state interactions and of the two-nucleon-induced decay mode.Comment: v1: 20 pages, 3 figures, 1 table, submitted for publication; v2: minor corrections, improved figures, published versio

Time evolution of the behaviour of Brazilian legislative Representatives using a complex network approach

The follow up of Representative behavior after elections is imperative for a democratic Representative system, at the very least to punish betrayal with no re-election. Our goal was to show how to follow Representatives' and how to show behavior in real situations and observe trends in political crises including the onset of game changing political instabilities. We used correlation and correlation distance matrices of Brazilian Representative votes during four presidential terms. Re-ordering these matrices with Minimal Spanning Trees displays the dynamical formation of clusters for the sixteen year period, which includes one Presidential impeachment. The reordered matrices, colored by correlation strength and by the parties clearly show the origin of observed clusters and their evolution over time. When large clusters provide government support cluster breaks, political instability arises, which could lead to an impeachment, a trend we observed three years before the Brazilian President was impeached. We believe this method could be applied to foresee other political storms.Comment: 11 pages, 4 Figure

Pusat Pembinaan Bulutangkis Berstandar Internasional Di Kota Malang

Regenerasi atlet Indonesia di cabang olahraga bulutangkis seolah berhenti, salah satu faktor penghambat regenerasi atlet adalah sistem pelatihan nasional yang masih terpusat. PB PBSI saat ini mulai mengembangkan program pelatihan desentralisasi dengan mengoptimalkan PBSI cabang di setiap daerah salah satunya Kota Malang. Diharapkan dengan adanya pusat pembinaan di Kota Malang mampu meningkatkan prestasi atlet bulutangkis Kota Malang di tingkat nasional dan mengharumkan nama Indonesia dalam olahraga bulutangkis Internasional. Proses perancangan ini didapat dengan menggunakan metode deskriptif dan programatik. Dari data komparasi yang sudah ada, kemudian dikombinasikan dengan studi literatur baik pada fasilitas pembinaan, sistem struktur bentang panjang, dan data penunjang lainnya untuk kemudian dijadikan sebagai parameter desain Pusat Pembinaan Bulutangkis Berstandar Internasional di Kota Malang. Pusat pembinaan bulutangkis berstandar Internasional di Kota Malang adalah sebuah jawaban atas tingginya antusias masyarakat Kota Malang terhadap olahraga bulutangkis dan merupakan wadah pembinaan atlet bulutangkis Kota Malang dengan fasilitas standar Internasional yang juga dilengkapi fasilitas penunjang seperti asrama atlet dan lainnya sesuai acuan BWF

Exact solutions for the KdV6 and mKdV6 Equations via tanh-coth and sech Methods

The tanh-coth method is used to seek solutions to obtain solutions to the new integrable sixthorder Korteweg-de Vries equation (KdV6). Following the analogy between the Korteweg-de Vries equation (KdV) and the modified Korteweg-de Vries equation (MKdV) we construct a new system equivalent to KdV6 from which exact solutions to original equation and derived, during the sech method

Assistência pré-natal no Sul do Brasil: cobertura, tendência e disparidades

OBJECTIVE: To estimate coverage, examine trend and assess the disparity reduction regarding household income during prenatal care between mothers living in Rio Grande, state of Rio Grande do Sul, in 2007, 2010, 2013 and 2016. METHODS: This study included all recent mothers living in this municipality, between 1/1 and 12/31 of those years, who had a child weighing more than 500 grams or 20 weeks of gestational age in one of the only two local maternity hospitals. Trained interviewers applied, still in the hospital and up to 48 hours after delivery, a unique and standardized questionnaire, seeking to investigate maternal demographic and reproductive characteristics, the socioeconomic conditions of the family and the assistance received during pregnancy and childbirth. To assess the adequacy of prenatal care, the criteria proposed by Takeda were used, which considers only the number of prenatal appointments and gestational age at initiation, and by Silveira et al., who in addition to these two variables, considers the achievement of some laboratory tests. Chi-square tests were used to compare proportions and assess the linear trend. RESULTS: The total of 10,669 recent mothers were included in this survey (96.8% of the total). Prenatal coverage substantially increased between 2007 and 2016. According to Takeda, it rose from 69% to 80%, while for Silveira et al., it increased from 21% to 55%. This improvement occurred for all income groups (p &lt; 0.01). The disparity between the extreme categories of income reduced, according to Takeda, and increased according to Silveira et al. CONCLUSIONS: The provision of prenatal care, considering only the number of appointments and the early start, occurred in greater proportion among the poorest. However, only the richest recent mothers were contemplated with more elaborate care, such as laboratory tests, which increased the disparities in the provision of prenatal care.OBJETIVO: Estimar a cobertura, examinar a tendência e avaliar se houve redução da disparidade em relação à renda familiar na realização de pré-natal adequado entre puérperas residentes em Rio Grande, RS, nos anos de 2007, 2010, 2013 e 2016. MÉTODOS: Foram incluídas neste estudo todas as puérperas residentes nesse município que, entre 1/1 a 31/12 desses anos, tiveram filho com peso superior a 500 gramas ou 20 semanas de idade gestacional em alguma das duas únicas maternidades locais. Entrevistadoras treinadas aplicaram, ainda no hospital e em até 48 horas após o parto, questionário único e padronizado, buscando investigar as características demográficas e reprodutivas maternas, as condições socioeconômicas da família e a assistência recebida durante a gestação e parto. Para avaliação da adequação do pré-natal, foram utilizados os critérios propostos por Takeda, que considera apenas o número de consultas pré-natais e a idade gestacional de início, e de Silveira et al., que além dessas duas variáveis, leva em conta a realização de alguns testes laboratoriais. Foram utilizados os testes qui-quadrado para comparar proporções e avaliar tendência linear. RESULTADOS: Foram incluídas neste inquérito 10.669 puérperas (96,8% do total). Verificou-se substancial aumento na cobertura de pré-natal adequado entre 2007 e 2016. Segundo Takeda, passou de 69% para 80%, enquanto para Silveira et al. aumentou de 21% para 55%. Essa melhora no período ocorreu para todos os grupos de renda (p &lt; 0,01). Houve redução na disparidade entre as categorias extremas de renda segundo Takeda e aumento acentuado segundo Silveira et al. CONCLUSÕES: A oferta de pré-natal, considerando apenas o número de consultas e o início precoce, ocorreu em maior proporção entre as mais pobres. No entanto, ao oferecer cuidados mais elaborados, como exames laboratoriais, estes alcançaram principalmente as puérperas mais ricas, aumentando assim as disparidades na oferta da assistência pré-natal
