The Hotelling's  control chart, is the most widely used multivariate procedure for monitoring  two or more related quality characteristics, but it’s power lacks the desired performance in detecting small to moderate shifts. Recently, the variable sampling intervals (VSI) control scheme in which the length of successive sampling intervals is determined upon the preceding values has been proved t...

As CMOS technology scales down, the design of ESD protection circuits becomes more challenging. There are some disadvantages for the actual power clamp circuit. In this paper, an optimization ESD power clamp circuit is proposed. The new clamp circuit adopts the edge triggering True Single Phase Clocked Logic (TSPCL) D flip-flop to turn on and time delay, it has the advantage of dynamic transmis...

BACKGROUND The human upper digestive tract microbial community (microbiota) is not well characterized and few studies have explored how it relates to human health. We examined the relationship between upper digestive tract microbiota and two cancer-predisposing states, serum pepsinogen I/pepsinogen II ratio (PGI/II; predictor of gastric cancer risk) and esophageal squamous dysplasia (ESD; the p...

one of the most important problems of the designs proposed by traditional economic-statistical approaches of control charts is inefficiency in the face of uncertainty. uncertainty in the parameters of economic-statistical models may lead to failure in rapidly detecting changes in processes and impose greater costs to the organization. monitoring the machining process in an automotive industry e...

AIM The efficacy of pre-procedure oral proton pump inhibitor (PPI) administration for gastric endoscopic submucosal dissection (ESD) is unclear. This study evaluated oral PPI administration effectiveness on the day of ESD to prevent post-ESD bleeding. METHODS This study examined 55 patients who underwent ESD for gastric neoplasm. Group A comprised 31 patients who took rabeprazole sodium (RPZ)...

OBJECTIVES/HYPOTHESIS To compare long-term symptomatic outcomes between external transcervical (ET) and endoscopic stapling diverticulotomy (ESD) surgeries for Zenker's diverticulum. STUDY DESIGN Retrospective review. METHODS Patients undergoing surgery for Zenker's diverticulum surgery between 1998 and 2010 with at least 1 year follow-up were telephoned and questioned for dysphagia, chokin...

Background and study aims  The adequate visualization of the dissection line, inside the submucosal layer, supposes the main challenging issue in ESD. For this reason, several counter traction methods have been developed focused on overcoming this handicap. One of which, Magnetic anchor guided - ESD (MG-ESD) is an attractive alternative. However, the usefulness of this approach has been scarcel...

The sensitivity level of resistors used in electronic equipment to an electrostatic discharge (ESD) varies from a few hundred volts to a few tens of kilovolts. Ways to make resistors more robust to ESD are suggested. The influence on ESD robustness of resistive element's size, resistive pattern design and ohmic value is discussed. Foil and thin film technologies are compared. In order to test t...
