Rong, Hong Bing,Gang, Kong Fan,Biao, Chen Xiong,Yi, Wang Shu 대한전자공학회 1992 HICEC:Harbin International Conference on Electroni Vol.1 No.1
This paper proposes three kinds of gait for HT-II Quadruped Walking Robot. In order that HT-II Quadruped Walking Robot is able to walk stably on ground, a software is developed which consists of three parts; gait-table produce programe ; gait-table check programe and joint drive programe. These three kinds of gait form the basis for further studying of fusing of static and dynamic gaits.

Ma, Zhi-Bin,Kong, Xiao-Lin,Cui, Gang,Ren, Cui-Cui,Zhang, Ying-Jie,Fan, Sheng-Jin,Li, Ying-Hua Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.21
Background: The aim of this study was to investigate differences of miRNA-34a expression in benign and malignant colorectal lesions. Materials and Methods: Samples of cancer, paraneoplastic tissues and polyps were selected and total RNA was extracted by conventional methods for real-time PCR to detect the miRNA-34a expression. In addition, the LOVO colorectal cancer cell line was cultured, treated with the demethylating agent 5-azacytidine and screened for differentially expressed miRNA-34a. Results: After the drug treatment, the miRNA-34a expression of colorectal cancer cell line LOVO was increased and real-time PCR showed that levels of expression in both cell line and colorectal cancer tissues were low, as compared to paraneoplastic tissue (p<0.05). Polyps tissues had significantly higher expression than paraneoplastic and colorectal cancer samples (p<0.05). Conclusions: miRNA-34a-5p may play a role as a tumor suppressor gene in colorectal cancer, with involvement of DNA methylation.
Effect of Microstructure on Mechanical Property of Carbon Steel/Strainless Steel Rolling Clad Plate

The bonding interface microstructure and mechanical property of clad plate with different hot rolling schedules were researched. The results show that the carbide layer thickness of bonding interface increases firstly and then decreases with increasing reduction ratio. The carbide layer of bonding interface is the major factor relating to tensile strength, so the experimental values of clad plate are slightly higher than the calculated ones. Moreover, the bending strength of clad plate is mainly influenced by the thickness ratio and the carbide quantity of SS, while the carbide layer thickness of bonding interface is an important factor affects the bending strength.
