Circuit-level timing speculation has been proposed as a technique to reduce dependence on design margins and eliminating power/performance overheads. Recent work has proposed microarchitectural methods to dynamically detect and recover from timing errors in processor logic. To a large extent existing work has relied on statistical error models and has not(More)
Relevance feedback is a powerful query modification technique in the field of content-based image retrieval. The key issue in relevance feedback is how to effectively utilize the feedback information to improve the retrieval performance. This paper presents a relevance feedback scheme using Bayesian network model for feedback information adoption. Relevant(More)
BACKGROUND Multidrug resistance (MDR) in gastric cancer remains a major challenge to clinical treatment. Activating transcription factor 4 (ATF4) is a stress response gene involved in homeostasis and cellular protection. However, the expression and function of ATF4 in gastric cancer MDR remains unknown. In this study, we investigate whether ATF4 play a role(More)
Based on the dynamic nonlinearities of robot manipulators, a fuzzy immune PD-type control algorithm is proposed for robot trajectory tracking. The algorithm combines fuzzy control, immune feedback mechanism of organism with conventional PID control. In the algorithm, the suppression number of suppression cells is described by a nonlinear function, which is(More)
MicroRNAs (miRNAs) have been implicated to play a central role in the development of drug resistance in a variety of malignancies. However, many studies were conducted at the in vitro level and could not provide the in vivo information on the functions of miRNAs in the anticancer drug resistance. Here, we introduced a dual reporter gene imaging system for(More)
BACKGROUND Cardiovascular disease is the leading cause of mortality among peritoneal dialysis (PD) patients in Macao. Increased arterial stiffness determined by pulse wave velocity (PWV) has been established as an independent predictor of cardiovascular mortality in end-stage renal disease patients. The present study aims to investigate the relationship(More)
Circuit-level timing speculation has been proposed as a technique to reduce dependence on design margins, eliminating power and performance overheads. Recent work has proposed microarchitectural methods to dynamically detect and recover from timing errors in processor logic. This work has not evaluated or exploited the disparity of error rates at the level(More)
