| 1 | Analytical optimization on GNSS buoy array for underwater positioning显示文摘Global navigation satellite system(GNSS)/acoustic positioning precision is determined by the positioning geometry and the ranging precision;thus optimizing GNSS buoys array is meaningful to improve the positioning accuracy and reliability.An analytical method is proposed for optimizing the GNSS buoys array with regard to the cutoff angle constraints for underwater acoustic observations.For the practical limitation of coplanarity of GNSS buoys and the cutoff angle,an algorithm is proposed to analytically minimize the position dilution of precision(PDOP).The proposed method is validated to give complete solutions of PDOP minimization with five GNSS buoys.At last,in order to search a best configuration among the PDOP solution set,we propose a search algorithm to get the solution with the smallest geometric dilution of precision(GDOP).It indicates that within a given region,the GDOP minimization at the center of a region is equivalent to the PDOP mean minimization over the region.The relation between the positioning accuracy and the positioning geometry with five known points is illustrated in an experiment performed in South China Sea. | Ke Qi Guoqing Qu Shuqiang Xue Tianhe Xu Xiaoqing Su Yixu Liu Jun Wan | 2019 | Acta Oceanologica Sinica2019，38，7： | 2 |

| 6 | Effects of Bradykinin on the Expression of Interleukin-6 in C6 Glioma Cells显示文摘OBJECTIVE There is a close correlation between interleukin-6 (IL-6) and malignant proliferation of gliomas. We investigated the effect of bradykinin on the expression of IL-6 in C6 glioma cells. METHODS Semi-quantitive RT-PCR and radioimmunoassay were used to examine the effect of bradykinin on the expression of IL-6 in C6 glioma cells and on the level of IL-6 in the culture medium. RESULTS Using semi-quantitive RT-PCR , the expression of IL-6 mRNA was examined in C6 glioma cells at 0, 5, 10,15, 30, 60 min following addition of 1 μmol/L bradykinin. There was no statistical difference in expression of IL-6 mRNA between the treatment and control groups (P>0.05) and IL-6 was not detected in the cell culture medium. CONCLUSION Within an hour, IL-6 expression in C6 glioma cells is not induced by bradykinin, suggesting that its clinical application may be useful as a potential therapeutic agent for tumors of the central nervous system. | Zhenhua Wang Yixue Xue | 2007 | Chinese Journal of Clinical Oncology2007，4，1： | 0 |
