ÐThe speed of arithmetic calculations in configurable hardware is limited by carry propagation, even with the dedicated hardware found in recent FPGAs. This paper proposes and evaluates an approach called delayed addition that reduces the carry-propagation bottleneck and improves the performance of arithmetic calculations. Our approach employs the idea used(More)
OBJECTIVES The trail investigated the effect of small dose sufentanil or fentanyl administrated before the end of surgery in reducing the incidence of emergence agitation after anesthesia with sevoflurane in preschool children undergoing ophthalmology surgery, and the incidence of emergence agitation of sevoflurane anesthesia. METHODS From September 2011(More)
The major pathogens of hand, foot and mouth disease (HFMD) in Beijing, China from 2007 to 2009 were identified in this study. A total of 186 HFMD cases were included, and 136 cases (73%) were positive for enterovirus (EV). In 2007, 75% (27/36) were Coxsackievirus A16 (CA16) positive and 19% (7/36) were Enterovirus 71 (EV71) positive cases. However, EV71 was(More)
Design rule checking (DRC) is an important step in VLSI design in which the widths and spacings of design features in a VLSI circuit layout are checked against the design rules of a particular fabrication process. In the past, some efforts to build hardware accelerators for DRC have been proposed, but these efforts were hobbled by the fact that it is often(More)
—P2P network is open, anonymous and dynamical in contrast with conventional network. It's full of dishonesty, deceit, selfishness. It's necessary to build a robust security infrastructure system. The one important module of security infrastructure is to identify the users in transactions. This paper will propose an identification solution based on PKI. In(More)
