TL;DR: Prevalence of overweight and obesity joined is higher among females and more than half of the women among 50 and 69 years old, from Northeast and Southeast regions of Brazil have overweight or obesity.
Abstract: OBJETIVO: Avaliar a prevalencia de sobrepeso e obesidade em criancas, adolescentes, adultos e idosos brasileiros das regioes Nordeste e Sudeste; METODOS: Avaliacao antropometrica de 17.184 pessoas, estudadas na Pesquisa sobre Padroes de Vida (PPV) realizada pelo IBGE em 1996/97, atraves do indice de massa corporal sendo usados como limite para sobrepeso e obesidade os valores propostos por Cole et al. por permitirem uma continuidade de criterio de sobrepeso e obesidade na infância, adolescencia e idade adulta. RESULTADOS: Predominio do sexo feminino, 53,1%, na populacao estudada. A media de idade foi de 29 anos e 5 meses (desvio padrao de ± 20 anos), a mediana foi de 25 anos e 6 meses. A prevalencia de sobrepeso foi de 10,8% entre criancas, 9,9% nos adolescentes e 28,3% entre adultos e a de obesidade foi 7,3%, 1,8% e 9,7%, respectivamente. Observado um aumento gradativo da prevalencia de sobrepeso e obesidade desde a infância ate a idade adulta, com declinio entre os idosos. CONCLUSOES: Prevalencia conjunta de sobrepeso e obesidade na populacao brasileira e maior no sexo feminino sendo que mais da metade das mulheres das regioes Nordeste e Sudeste do Brasil, com idade entre 50 e 69 anos, tem sobrepeso e/ou obesidade. A comparacao de estudos de prevalencia de sobrepeso e obesidade na infância e adolescencia e dificultada pela escassez de estudos populacionais nacionais e diversidade de criterios utilizados na avaliacao nutricional.

17 May 2004TL;DR: This paper provides an extensive analysis of pre-stored streaming media workloads, focusing on the client interactive behavior, to identify qualitative similarities and differences in the typical client behavior for the three workload classes and to provide data for generating realistic synthetic workloads.
Abstract: This paper provides an extensive analysis of pre-stored streaming media workloads, focusing on the client interactive behavior. We analyze four workloads that fall into three different domains, namely, education, entertainment video and entertainment audio. Our main goals are: (a) to identify qualitative similarities and differences in the typical client behavior for the three workload classes and (b) to provide data for generating realistic synthetic workloads.

TL;DR: The first-order Hermite-Gaussian modes are employed in an experiment in order to show that, by manipulating the pump beam, one can control the resulting two-photon interference behavior.
Abstract: We consider multimode two-photon interference at a beam splitter by photons created by spontaneous parametric down-conversion. The resulting interference pattern is shown to depend upon the transverse spatial symmetry of the pump beam. In an experiment, we employ the first-order Hermite-Gaussian modes in order to show that, by manipulating the pump beam, one can control the resulting two-photon interference behavior. We expect these results to play an important role in the engineering of quantum states of light for use in quantum information processing and quantum imaging.

TL;DR: This work provides the complete characterization of the classical correlations and the corresponding maximal quantum violations for the case of n >= 4 observables X_0, ...,X_{n-1}, where each consecutive pair {X_i, X_{i+1}}, sum modulo n, is jointly measurable.
Abstract: The problem of separating classical from quantum correlations is, in general, intractable and has been solved explicitly only in a few cases. In particular, known methods cannot provide general solutions for an arbitrary number of settings. We provide the complete characterization of the classical correlations and the corresponding maximal quantum violations for the case of $n\ensuremath{\ge}4$ observables ${X}_{0},...,{X}_{n\ensuremath{-}1}$, where each consecutive pair ${{X}_{i},{X}_{i+1}}$, sum $\mathrm{mod}\phantom{\rule{0.16em}{0ex}}n$, is jointly measurable. This generalizes both the Clauser-Horne-Shimony-Holt and the Klyachko-Can-Binicio\ifmmode \breve{g}\else \u{g}\fi{}lu-Shumovsky scenarios, which are the simplest ones for locality and noncontextuality, respectively. In addition, we provide explicit quantum states and settings with maximal quantum violation and minimal quantum dimension.
