With the popularity of digital camera and the application requirement of digitalized document images, using digital cameras to digitalize document images has become an irresistible trend. However, the warping of the document surface is sometimes unavoidable. The warped surface can lead to document image distortion, especially at the book spine. This impacts(More)
The characteristics of spatial and temporal distribution of tropospheric NO2 column density concentration over China are presented, on the basis of measurements from the satellite instruments GOME and SCIAMACHY. From these observations, monthly averaged tropospheric NO2 variations are determined for the period of 1997 to 2006. The trend and seasonal cycle(More)
BACKGROUND In 2010, a universal nomenclature for varicella-zoster virus (VZV) clades was established, which is very useful in the monitoring of viral evolution, recombination, spread and genetic diversity. Currently, information about VZV clades has been disclosed worldwide, however, there are limited data regarding the characterization of circulating VZV(More)
The sediment in Dianchi Lake, a hypereutrophic plateau lake in southwest China, was investigated and the concentration of heavy metals (Cu, Cr, Ni, Zn, Pb, Fe, Mn, and Cd) in the sediment and sediment properties were determined. Their spatial distribution and sources were analyzed using multivariate statistics. The result indicated that the studied metals(More)
We have previously explored the possibilities of allogenic intervertebral disc (IVD) curing disc degeneration disease in clinical practice. The results showed that the motion and stability of the spinal unit was preserved after transplantation of allogenic IVD in human beings at 5-year follow-up. However, mild degeneration was observed in the allogenic(More)
The work presented in this paper is a kind of application based on Chinese syntactic parsing. It is theoretic discussion to define term names. The definition of terms provides patterns and structures for term concepts and is the data basis of knowledge discovery. In this paper, the corpora of electronics and computer domain are firstly segmented and tagged(More)
Carbonation technology with CO(2) absorption was used to enhance the stabilization of heavy metals in fresh fly ash from a municipal solid waste incinerator (MSWI). The influence of fundamental parameters affecting the stabilization of heavy metals, especially Pb and diffusivity and reactivity of CO(2), was evaluated. The results indicated that the addition(More)
We studied the effects of the presence of the HLA-DR15 allele on the experimental and clinical features of myelodysplastic syndrome (MDS) by assessing the clinical data of 136 patients with MDS. We observed that the frequency of HLA-DR15 expression in MDS patients (38.7%) was significantly higher than that in the healthy controls (p < 0.01). We noted the(More)
The purpose of this study was the use of rhodamine 123 (Rho123) accumulation in peripheral blood CD8(+)cells as a surrogate indicator to evaluate the modulating effect of P-glycoprotein (P-gp) inhibitors in the multidrug resistance (MDR) tumor-bearing mouse model. Rho123 was administered to mice, and the fluorescence level in CD8(+) cells was measured.(More)
