The introduction of turbo codes and the rediscovery of low-density parity-check (LDPC) codes have revolutionized coding theory and practice. Such modern codes offer outstanding coding gain over traditional (e.g., algebraic or convolutional) codes – more than 3 dB in many cases. While good modern codes have been demonstrated for most operational scenarios of interest, no one simple code structur...

between 1993-1996 seventy-three consecutive patients (33 m, 40 f, mean age 35.4) with newly diagnosed achalasia underwent one or more pneumatic dilatations with the rigiflex balloon using a protocol of graded dilatation with a fixed inflation pressure of 10 psi and constant duration of 30 seconds for all patients without using fluoroscopy. using vantrappen's classification for assessment o...

Improving health-related quality of life among persons with diabetes is a public health goal. This study sought to assess trends in self-rated “fair and poor health” among Spanish adults with diabetes, and to identify factors associated with “fair and poor health” using data from all five National Health Surveys conducted from 1993 to 2003.The most relevant finding of this study is that, among ...

Main results At the individual level, the perception of fair or poor health was strongly associated with age, sex, socio-economic position (as measured by education and household income), smoking, obesity, and infrequent exercise. Overall, a handful of individual factors accounted for much of the variation between health regions in reporting of fair or poor health. There was an additional influ...

The authors investigated the association between observed neighborhood conditions and lower-body functional limitations (LBFLs) using data from 563 subjects of the African-American Health Study. This population-based cohort received in-home evaluations. Five items involving LBFL were obtained at baseline (2000-2001) and 3 years later. Subjects were considered to have LBFL if they reported diffi...

Background: Intra-articular T- type or Y- type fractures of the distal end of the humerus are relatively rare, and consequently few surgeons will be able to attain extensive experience with the surgical treatment of these injuries. The current emphasis is on operative intervention with rigid internal fixation and early mobilization. Methods: In this prospective and retrospective study, we r...

INTRODUCTION Self-rated health is a widely used health outcome measure that strongly correlates with physical and mental health status and predicts mortality. This study identified the set of predictors of fair/poor self-rated health in adult female and male populations of Armenia during a period of long-lasting socio-economic transition to a market economy. METHODS Differences in self-rated ...
