Search for new physics in the multijet and missing transverse momentum final state in proton-proton collisions at √s=7TeV

Abstract: A search for physics beyond the standard model is performed in events with at least three jets and large missing transverse momentum produced in proton-proton collisions at a center-of-mass energy of √s=7 TeV. No significant excess of events above the expected backgrounds is observed in 4.98 fb^(-1) of data collected with the CMS detector at the Large Hadron Collider. The results are presented in the context of the constrained minimal supersymmetric extension of the standard model and more generically for simplified models. For the simplified models of gluino-gluino and squark-squark production, gluino masses below 1.0 TeV and squark masses below 0.76 TeV are excluded in case the lightest supersymmetric particle mass is below 200 GeV. These results significantly extend previous searches.

Sexual culture, HIV transmission, and AIDS research

Abstract: The spread of the international AIDS pandemic has drawn attention to the urgent need for data on human sexual behavior; yet the absence of an established tradition of theory and method in sex research has limited the development of initiatives in this area. This has been particularly evident in the lack of attention given to the ways in which cross‐cultural differences structure the meaning of sexual experience. While survey research can play an important role in documenting sexual behavior, qualitative research on sexual culture is equally important in order to develop a framework for the comparative analysis of behavioral data. This article seeks to contribute to the development of theory and method in sex research by outlining key research issues and possible methodologies for the qualitative investigation of sexual culture in relation to HIV/AIDS.

Economic Impact of Dengue: Multicenter Study across Four Brazilian Regions

Abstract: Dengue is an increasing public health concern in Brazil. There is a need for an updated evaluation of the economic impact of dengue within the country. We undertook this multicenter study to evaluate the economic burden of dengue in Brazil.

Confidence intervals for the kappa statistic

Abstract: The command kapci calculates 100(1 –α)% confidence intervals for the kappa statistic using an analytical method in the case of dichotomous variables or bootstrap for more complex situations. For in...
