We evaluate the effectiveness of statistical gate sizing to minimize circuit power. We develop reliable posynomial models for delay and power that are accurate to within 5-10% of 130nm library data. We formulate statistical sizing as a geometric program, accounting for randomness in gate delays. For various ISCAS-85 circuits, statistical sizing at a 99.8% target yield provides 25% power reducti...

A pattern in which nucleotide transitions are favored several fold over transversions is common in molecular evolution. When this pattern occurs among amino acid replacements, explanations often invoke an effect of selection, on the grounds that transitions are more conservative in their effects on proteins. However, the underlying hypothesis of conservative transitions has never been tested di...

While young people’s alcohol consumption has fallen sharply in the United Kingdom and other high-income countries, universities remain places where heavy drinking is routine normative. Drawing on interviews with undergraduate students, this article explores how part of students negotiate a sense belonging form personal relationships. Theoretical work relationality used to make students’ encount...

This article examines how Indonesia, the world’s third-largest democracy, came to define sexuality for its general population once intimacy was brought into public sphere. However, Islamic version had predominantly been based on interpretations pushed by politically hardline Islamist groups. The influence of this lobby (to be referred as belonging stream ‘conservative Islam’) grew steadily afte...

A 23 year old female patient came to our Department of Conservative Dentistry and Endodontics, Kamineni Institute of Dental Sciences, Nalgonda, with a chief complaint of pain in the mandibular left second molar. The patient had no significant medical history. Subjective symptoms of prolonged sensitivity to hot and cold were present. The objective symptoms were observed as percussion sensitivity...
