One of the intriguing characteristics of the 2003 severe acute respiratory syndrome (SARS) epidemics was the occurrence of super spreading events (SSEs). Here, the authors report the results of identifying the occurrence of SSEs in the Hong Kong and Singapore epidemics using mathematical and statistical analysis. Their predicted occurrence of SSEs agreed(More)
Isoflurane enhances myocardial functional recovery and improves energy levels after ischemia. We sought to determine whether isoflurane-induced cardioprotection is mediated by protein kinase C (PKC). The Langendorff model was used, and isolated perfused rat hearts were separated into untreated, isoflurane, chelerythrine (PKC inhibitor) plus isoflurane, and(More)
In our study, metabolomics was used to investigate biochemical changes in the early stages of rats focal cerebral ischemia/reperfusion (I/R) injury. Cerebrospinal fluid (CSF) samples at 0, 0.5, 1, 3, and 6 h of reperfusion (n = 10), based on (1)H NMR spectroscopy and multivariate data analyses, were tested to analyze the changing of metabolites during the(More)
We describe a Chinese to English Machine Translation system developed at the Johns Hopkins University for the NIST 2003 MT evaluation. The system is based on a Weighted Finite State Transducer implementation of the alignment template translation model for statistical machine translation. The baseline MT system was trained using 100,000 sentence pairs(More)
The paper currency characteristic data acquisition system is a real-time subsystem of bill acceptor system based on ARM and uClinux, but uClinux can not meet the real-time requirement of the data acquisition system. After considering the characteristic of uClinux and the hardware of the data acquisition system, a method for improving the real-time ability(More)
A novel direct identification of double-strand DNA is proposed by using real-time enzyme-digestion in a resonant-cantilever embedded microfluidic chip. The new gene-level detection method is expected to replace the conventional DNA-hybridization based gene-detection that suffers from not only nonspecific adsorption induced false-positives but also(More)
PURPOSE This study focuses on investigating the expression correlation of vimentin, survivin and p53 in clear cell renal cell carcinoma (ccRCC) and the clinical significance. METHODS The mRNA and protein expression levels of the vimentin, survivin and p53 were determined in ccRCC and adjacent normal renal tissues, using quantitative real-time-polymerase(More)
On the basis of microgravimetric sensing data, an analytical modeling method is proposed for comprehensive evaluation and optimization of gas sensing or adsorbing related functional materials. Resonant microcantilever is loaded with the material to be evaluated for a gravimetric sensing experiment. With sensing isotherm curves obtained at different(More)
