—A design methodology for low power MOS distributed amplifiers (DAs) is presented. The bias point of the MOS devices is optimized so that the DA can be used as a low-noise amplifier (LNA) in broadband applications. A prototype 9-mW LNA with programmable gain was implemented in a 0.18-m CMOS process. The LNA provides a flat gain, 21 , of 8 0.6 dB from DC to(More)
Player satisfaction is particularly difficult to ensure in online games, due to interactions with other players. In adversarial multiplayer games, matchmaking typically consists in trying to match together players of similar skill level. However, this is usually based on a single-skill value, and assumes the only factor of “fun” is the game(More)
A design methodology is presented for low power distributed amplifiers and is used for the design of a mW LNA with programmable gain implemented in a m CMOS process. The LNA provides a gain of dB from DC to GHz, with an input match of dB and an output match of dB over the entire band. The IIP3 is dBm, and the NF ranges from to dB. The gain is tunable from(More)
Although therapeutic effect of adoptive transfer of endothelial progenitor cells (EPC) has been well-substantiated, the actual engraftment is relatively low compared to a robust functional improvement of vasculopathy. Cellular mechanisms governing this action remain elusive. A recently discovered cell-cell communication via tunneling nanotube (TNT)(More)
Ensuring security in wireless ad hoc networks is absolutely necessary and a must for any security-critical applications. In this paper, we report our progress in the development of an agent-based cooperative anomaly detection scheme for wireless ad hoc networks. The approach addresses the underlying distributed and cooperative nature of wireless ad hoc(More)
Endothelial dysfunction and activation occur in the vasculature and are believed to contribute to the pathogenesis of cardiovascular diseases. We have shown that 20-hydroxy-5,8,11,14-eicosatetraenoic acid (20-HETE), a cytochrome P450 4A-derived eicosanoid that promotes vasoconstriction in the microcirculation, uncouples endothelial nitric-oxide synthase(More)
It is widely believed that disclosure quality improves investors' welfare by reducing cost of capital in a competitive market. This paper examines this conventional wisdom by studying a production economy in which disclosure influences a firm's investment decisions. I demonstrate three points. First, cost of capital could increase with disclosure quality(More)
