STUDY OBJECTIVES Identify polysomnographic and demographic factors associated with elevation of nocturnal end-tidal CO2 in patients with obstructive sleep apnea. METHODS Forty-four adult patients with obstructive sleep apnea were selected such that the maximal nocturnal end-tidal CO2 was below 45 mm Hg in 15 studies, between 45 and 50 mm Hg in 14, and above 50 mm Hg in 15. Measurements includ...

Television markets in the CEE region have experienced rapid growth in recent years. The number of multichannel TV households (households that can receive cable or satellite television, as well as terrestrial channels) grew by almost 50 percent and the share of Pay TV increased to over 40 percent between 2008 and 2010. Demand for multichannel TV in the region, however, is far from reaching satur...

OBJECTIVE The purpose of this study was to determine the effect of body fat distribution on plasma lipid and lipoprotein concentrations in healthy individuals. METHODS Subjects were 290 women and 223 men aged 20-66 years old. Lipid panels were obtained and truncal adiposity measurements were determined by total body dual energy x-ray absorptiometry (DXA). Physical activity was measured using ...

This article investigates how a …rm’s …nancial strength a¤ects its dynamic decision to invest in R&D. We estimate a dynamic model of R&D choice using data for German …rms in high-tech manufacturing industries. The model incorporates a measure of the …rm’s …nancial strength, derived from its credit rating, which is shown to lead to substantial di¤erences in estimates of the costs and expected lo...

That tired Ten-Percent claim pops up all the time. Last year, national magazine ads for U.S. Satellite Broadcasting showed a drawing of a brain. Under it was the caption, "You only use 11 percent of its potential." Well, they're a little closer than the ten-percent figure, but still off by about 89 percent. In July 1998, ABC television ran promotional spots for "The Secret Lives of Men," one of...

An information retrieval performance measure that is interpreted as the percent of perfect performance (PPP) can be used to study the effects of the inclusion of specific document features or feature classes or techniques in an information retrieval system. Using this, one can measure the relative quality of a new ranking algorithm, the result of incorporating specific types of metadata or folk...
