PROBLEM/CONDITION CDC began abortion surveillance in 1969 to document the number and characteristics of women obtaining legal induced abortions. REPORTING PERIOD COVERED This report summarizes and describes data voluntarily reported to CDC regarding legal induced abortions obtained in the United States in 2004. DESCRIPTION OF SYSTEM For each year since 1969, CDC has compiled abortion data b...

BACKGROUND There is little information about height and weight status of Palestinian adolescents. The objective of this paper was to assess the prevalence of stunting, underweight, and overweight/obesity among Palestinian school adolescents (13-15 years) and associated sociodemographic factors in 2 major governorates in the West Bank. METHODS A Cross-sectional survey was conducted in 2005 com...

Two algorithms are presented for performing a Fast Fourier Transform on a vector computer and are compared on the Control Data Corporation STAR-100. The relative merits of the two algorithms are shown to depend upon whether only a few or many independent transforms are desired. A theorem is proved which shows that a set of independent transforms can be computed by performing a partial transform...

Traps are widely employed for sampling and monitoring mosquito populations for surveillance, ecological and fauna studies. Considering the importance of assessing other technologies for sampling mosquitoes, we addressed the effectiveness of Mosquito Magnet® Independence (MMI) in comparison with those of the CDC trap with CO2 and Lurex3® (CDC-A) and the CDC light trap (CDC-LT). Field collections...

In April 2006, the World Health Organization (WHO) released new international growth charts for children aged 0-59 months. Similar to the 2000 CDC growth charts, these charts describe weight for age, length (or stature) for age, weight for length (or stature), and body mass index for age. Whereas the WHO charts are growth standards, describing the growth of healthy children in optimal condition...

Hybrid systems have been an active area of research for a number of years. Recently a consensus is beginning to emerge among researchers about theoretical and applied problems related to control of hybrid systems that are both important and tractable. In this overview paper we survey recent research advances and highlight some of the open problems.

Pure SU(4) gauge theory is simulated by Monte Carlo methods on an 8~lattice. The method of Metropolis et al. is used to equilibriate the space—time lattice. All Wilson loops up to size 4 x 4 are calculated. Because of memory requirements we work on the 2 Mword CDC CYBER 205 at Colorado State University and take full advantage of the parallel processing capabilities of this vector machine.
