PURPOSE: Functional differences between the sexes are well documented. The causes of functional decline are complex, but in general, women report more functional decline and have a greater prevalence of disabling chronic conditions than do men. The role of exercise training in attenuating functional decline has not been studied extensively. ...

The decay B(d)-->phi K(S) is a special probe of physics beyond the standard model (SM), since it has no SM tree level contribution. Motivated by recent data suggesting a deviation from the SM for its time-dependent CP asymmetry, we examine supersymmetric explanations. Chirality preserving contributions are generically small, unless gluino ...

Active galaxies are characterized by prominent emission from their nuclei. In the 'unified' view of active galaxies, the accretion of material onto a massive compact object--now generally believed to be a black hole--provides the fundamental power source. Obscuring material along the line of sight can account for the observed differences ...

Lack of physical activity is a known determinant of obesity. Unfortunately, children become less and less active as they reach and progress through adolescence. This behavior leads to detrimental effects on body composition and other components of health-related physical fitness. Various types of exercise and activities have different effects on ...
