Cervicovaginal lavages from 752 pregnant women at term were investigated by polymerase chain reaction to evaluate human papillomavirus (HPV) infection prevalences and were compared with cervicovaginal samples from two series of nonpregnant subjects (504 healthy women attending a family planning service and 560 symptomatic patients attending a vaginitis outpatient service). The odds ratios (ORs)...

0018 Meningococcal meningitis in western Africa shows recurrent seasonal patterns every year. Epidemics typically start at the beginning of February and last until May. We can try to explain the observed patterns on the basis of some seasonally varying environmental factor that favors disease transmission. Air dryness produced by strong dust winds is the most likely candidate. But while there a...

It is shown how the Zak transform can be used to find nontrivial examples of functions f, g E L 2 ( 2 ) with f . g = 0 = F . C, where F, G are the Fourier transforms of f, g, respectively. This is then used to exhibit a nontrivial pair of functions h, keL2(T1), h # k, such that I h I = 1 k 1 , I H I = I K 1 . A similar construction is used to find an abundance of nontrivial pairs of functions h...

The concurrency is classified into two types: structured concurrency and nonstructured concurrency. After showing that the nonstructured concurrency cannot be represented by the conventional notations in the Petri net language, a method to represent such concurrency by the language is proposed. The proposed method allows us to utilize the existing approaches for analyzing properties of a nonstr...

Published by the IEEE Computer Society 0018-9162/11/$26.00 © 2011 IEEE preparation is not typically part of most undergraduate programs, especially at engineering institutions. Cultivating entrepreneurial thinking requires going beyond teaching business fundamentals and reviewing case studies; it requires learning through practice.2 To support active student engagement in entrepreneurial activi...

6 computer Published by the IEEE Computer Society 0018-9162/13/$31.00 © 2013 IEEE A presidential transition represents that moment when the invisible and the visible switch places. A new president steps from the wings to head the organization. The outgoing leader takes a bow for work well done and returns to serve the Society in other ways. The event tells us more about the organization than ab...

This pilot, randomized controlled trial analyzed the effects of a cognitive behavioral therapy (CBT, n = 20) for insomnia vs a sleep hygiene (SH, n = 20) program on the three attentional networks (alertness, orienting, and executive function) and other additional outcome measures (sleep, pain, depression, anxiety, and daily functioning) of fibromyalgia patients. The CBT group showed significant...
