Background and Aim: The aim of this study was to evaluate the clinical value of transient elastography (TE) for high‐risk esophageal varices (HREV) prediction in hepatitis‐B‐related cirrhosis patients.
Methods: A total of 238 patients with hepatitis B cirrhosis were prospectively enrolled. All patients had undergone TE and upper gastrointestinal endoscopy. Diagnostic value was assessed by the area...
Techniques of the using of digital frequency locked loop (DFLL) in the frequency-hopped spread-spectrum (FH-SS) systems are presented. The approach, presented in this paper, makes it possible to use an accurate DFLL in place of RF local oscillator (LO) especially in the fast FH-SS systems. A DFLL in place of LO has not been reported for fast FH-SS systems mainly because that type of frequency synthesizer...
Using cache in the voice platform based on VoiceXML (voice extensible makeup language) could reduce the cost of network bandwidth, server-load and access delay. By analyzing the cache model of voice platform, the fitting & predicting algorithm is proposed. It estimates the validity of the cached document by performing parameter fits to stochastic distribution and predicting the change probability...
