Pulling Punches : Congressional Constraints on the Supreme Court ’ s
To date, no study has found evidence that the U.S. Supreme Court is constrained by Congress in its constitutional decisions. We addressed the selection bias inherent in previous studies with a statute-centered, rather than a case-centered, analysis, following all congressional laws enacted between 1987 and 2000. We uncovered considerable congressional constraint in the Court’s constitutional ru...
متن کاملBig punches come in nanosizes for chemoprevention.
Literature to support the chemopreventive potential of several bioactive molecules has been prolific and convincing, but the clinical development of these agents has been slow. Major hurdles for development of bioactive chemoprevention approaches include low potency, lack of reliable formulations with high bioavailability that are suitable for oral administration, and relevant preclinical prima...
متن کاملDelivering Three Punches to Knockout Intracellular Bacteria
Cytotoxic lymphocytes kill bacteria-infected cells, but the mechanisms at work remain unclear. Walch et al. show that these lymphocytes deliver a toxic molecular trio in a two-step process, penetrating first the infected cells and then delivering bactericidal granzymes into the intracytoplasmic bacteria.

extinguished by the transfer. But the extent of the transformation is not yet clear. “It’s possible that what we are doing is turning everything into an oocyte,” says Gurdon. But he believes that oct4 expression is a good sign that the cells are at least headed toward becoming stem cells. Stem cell characteristics may develop only through sequential inductive events. But the optimists are hopin...
متن کاملA simple algorithm for stamping circular plates by hemispherical punches
This paper proposes a simple algorithm for solving the contact problems in relation to sheet stamping. The efficiency and reliability of the algorithm are demonstrated by an investigation of the stamping of elastic-plastic circular plates into a conical die with a hemispherical rigid punch. The analysis shows that the contact stress varies greatly with the punch displacement and deviates from t...
