Tumor cells from a human melanoma xenograft show better colony growth and plating efficiency in soft agar when incubated in a 5% O2 atmosphere that at a higher concentration of 20% O2. Exposure to low drug concentrations under a 20% (but not 5%) O2 atmosphere stimulated plating efficiency. Enhanced sensitivity (4- to 20-fold) to a variety of chemotherapeutic agents was seen in cells incubated u...

We study the implication of the time-dependent CP asymmetry in B → π + π − decays on the extraction of weak phases taking into account the precise measurement of sin 2β, obtained from the " gold-plated " mode B → J/ψKS. Predictions and uncertainties for the hadronic parameters are investigated in QCD factorization. Furthermore, independent theoretical and experimental tests of the factorization...

Direct contingency analysis has been shown to be important. Instead of this success providing a powerful foundation for major advances in all of the important areas of psychology, I fear that it is becoming a gold plated cage. My evidence: relatively narrow areas of interest are dominating the field, both applied and basic. We are not expanding, and a field not busy being born is a field that i...
