Fundamental tools of molecular structure elucidation are computer programs generating constitutional isomers and configurational isomers. A general disadvantage of the methods of algebraic stereoisomer generation by Nourse, Smith, Carhart and Djerassi is the restriction of the valences of the stereocenters to four. The present paper discusses an extension of this concept to higher-valence cente...

ID strongly predicts stock returns after controlling for firm characteristics and risk. High ID portfolios provide Carhart alphas of 56-81 basis points per month and stronger and less volatile operating performance. The Diversified Min...

Women's health specialists were rightfully alarmed by the April 2007 Supreme Court decision in Gonzales v. Carhart. In criminalizing the “intact dilation and extraction” abortion procedure and banning its use even to protect a woman's health, the U.S. Supreme Court has—with shocking ease— rejected science, overthrown legal precedent safeguarding women's health and seized authority over medical ...
