Optimization for power is always one of the most important design objectives in modern nanometer IC design. Recent studies have shown the effectiveness of applying multi-bit flip-flops to save the power consumption of the clock network. However, all the previous works applied multi-bit flip-flops at earlier design stages, which could be very difficult to(More)
Applying multi-bit flip-flops (MBFFs) for clock power reduction in modern nanometer ICs has been becoming a promising lower-power design technique. Many previous works tried to utilize as more MBFFs with larger bit numbers as possible to gain more clock power saving. However, an MBFF with a larger bit number may lead to serious crosstalk due to the close(More)
This study compared the extractability of Cd, Cu, Ni, Pb, and Zn by 8 extraction protocols for 22 representative rural soils in Taiwan and correlated the extractable amounts of the metals with their uptake by Chinese cabbage for developing an empirical model to predict metal phytoavailability based on soil properties. Chemical agents in these protocols(More)
Rhodostomin (Rho) is an RGD protein that specifically inhibits integrins. We found that Rho mutants with the P48A mutation 4.4-11.5 times more actively inhibited integrin α5β1. Structural analysis showed that they have a similar 3D conformation for the RGD loop. Docking analysis also showed no difference between their interactions with integrin α5β1.(More)
