BACKGROUND We previously reported the effect of dioscin on human gastric carcinoma SGC-7901 cells, but its effects on other gastric cancers are still unknown. PURPOSE The present paper aimed to demonstrate the activity of dioscin against human gastric carcinoma MGC-803 and MKN-45. STUDY DESIGN In our study, MGC-803 and MKN-45 cells were used to examine(More)
Dioscin, a natural product, has activity against glioblastoma multiforme, lung cancer and colon cancer. In this study, the effects of dioscin against human cervical carcinoma HeLa and SiHa cells were further confirmed, and the possible mechanism(s) were investigated. A transmission electron microscopy (TEM) assay and DAPI staining were used to detect the(More)
An O(N) algorithm is proposed for calculating linear response functions of non-interacting electrons. This program is simple and suitable to parallel-and vector-computation. Since it avoids O(N 3) computational effort of matrix diagonalization, it requires only O(N) computational efforts where N is the dimension of the statevector. The use of this O(N)(More)

Determining the make and model of an image's source camera is an important forensic problem. While significant research has been conducted towards developing new camera model identification algorithms, little research has focused on controlling the computational cost of these algorithms. This becomes an important issue if forensic algorithms are to be used(More)
This paper investigates an adaptive method of dim small target detection in infrared images with a complex background. We analyze in depth the characteristics of the background, the target, and the noise in the gray intensity, space and frequency domain of the images. The modified top-hat transformation using interrelated structuring elements is adopted to(More)
