PURPOSE The decline in U.S. adolescent fertility has accelerated since 2007. Modeling fertility change using behavioral data can inform adolescent pregnancy prevention efforts. METHODS We used data on sexual activity and contraceptive use from National Surveys of Family Growth for young women 15-19 years of age, and contraceptive failure rates, to estimate a Pregnancy Risk Index (PRI) for the...

Acute exposure to cigarette smoke provokes bronchoconstriction and increases the concentration of thromboxane (Tx) A2 in bronchoalveolar lavage (BAL) fluid. The purpose of this study was to investigate the role of TxA2 and cholinergic mechanisms in the airway response induced by exposure to cigarette smoke in guinea-pigs. Anaesthetized animals were exposed to 200 puffs of smoke for 10 min. The ...

Core to the mathematical innovations of space syntax is the concept of graph-radius. In this paper, the authors propose a new mathematical mechanism to provide a relative measure for the local/global configuration of an axial line. We propose that cumulative depth be redefined as CD = Sum (1/((di-1)^k)) where d is the depth from node i to the origin and k is a constant factor. This method is ba...

This note summarizes the results of a study of the identification of theH !WW !`` ` `0 signal for MH 0 = 170 GeV/c. This study is motivated by the papers written by M. Dittmar and H. Dreiner [1][2]. We carried out a similar study using Pythia to generate events and CMSIM calorimeter simulation for the jet veto, and compared with their results. We also show some comparison between Pythia and IS...
