BACKGROUND Physical activity (PA) reduces the risk of cardiovascular disease and physically active survivors of a cardiac event are at lower risk of recurrent events. We hypothesized that patients with a decreased PA, undergoing cardiac surgery, are at higher risk for a postoperative complicated recovery (PCR). METHODS Three thousand three hundred eighty two patients undergoing elective cardi...

Science Versus Stigma Stigma is an enormous obstacle to more effective drug abuse treatment. Widespread perceptions that addiction strips individuals of basic human qualities lead to selffulfilling predictions that those who are addicted cannot recover or ever play positive and productive social roles.

In this paper, we extend the construction of a fuzzy subgroup generated by a fuzzy subset to $L$-setting. This construction is illustrated by an example. We also prove that for an $L$-subset of a group, the subgroup generated by its level subset is the level subset of the subgroup generated by that $L$-subset provided the given $L$-subset possesses sup-property.

In this paper, we first discuss the structure of the Ramond N = 2 superconformal algebras. Then we classify the modules of the intermediate series over Ramond N = 2 superconformal algebra.
