| 1 | Parametric Problems in Power System Analysis:Recent Applications of Polynomial Approximation Based on Galerkin Method显示文摘In power systems, there are many uncertainty factors such as power outputs of distributed generations and fluctuations of loads. It is very beneficial to power system analysis to acquire an explicit function describing the relationship between these factors(namely parameters) and power system states(or performances). This problem, termed as parametric problem(PP) in this paper, can be solved by Galerkin method,which is a powerful and mathematically rigorous method aiming to seek an accurate explicit approximate function by projection techniques. This paper provides a review of the applications of polynomial approximation based on Galerkin method in power system PPs as well as stochastic problems. First, the fundamentals of polynomial approximation and Galerkin method are introduced. Then, the process of solving three types of typical PPs by polynomial approximation based on Galerkin method is elaborated. Finally, some application examples as well as several potential applications of power system PPs solved by Galerkin method are presented, namely the probabilistic power flow, approximation of static voltage stability region boundary, and parametric time-domain dynamic simulation. | Hao Wu Danfeng Shen Bingqing Xia Yiwei Qiu Yongzhi Zhou Yonghua Song | 2021 | Journal of Modern Power Systems and Clean Energy2021，9，1： | 4 |
| 2 | Application of fluorescence in situ hybridization in the detection of bladder transitional-cell carcinoma: A multi-center clinical study based on Chinese population显示文摘Objective:To evaluate the diagnostic value of fluorescence in situ hybridization(FISH)in bladder cancer.Methods:We enrolled healthy volunteers and patients who were clinically suspected to have bladder cancer and conducted FISH tests and cytology examinations from August 2007 to December 2008.Receiver operating characteristic(ROC)curve analysis was performed and the area under curve(AUC)values were calculated for both the FISH and urine cytology tests.Results:A cohort of 988 healthy volunteers was enrolled to establish a reference range for the normal population.A total of 4807 patients with hematuria were prospectively,randomly enrolled for the simultaneous analysis of urine cytology,FISH testing,and a final diagnosis as determined by the pathologic findings of a biopsy or a surgically-excised specimen.Overall,the sensitivity of FISH in detecting transitional-cell carcinoma was 82.7%,while that of cytology was 33.4%(p<0.001).The sensitivity values of FISH for non-muscle invasive and muscle invasive bladder transitional-cell carcinoma were 81.7%and 89.6%,respectively(p=0.004).The sensitivity values of FISH for low and high grade bladder cancer were 82.6%and 90.1%,respectively(p=0.002).Conclusion:FISH is significantly more sensitive than voided urine cytology for detecting bladder cancer in patients evaluated for gross hematuria at all cancer grades and stages.Higher sensitivity using FISH was obtained in high grade and muscle invasive tumors. | Liqun Zhou Kaiwei Yang Xuesong Li Yi Ding Dawei Mu Hanzhong Li Yong Yan Jinyi Li Dongwen Wang Wei Li Yulong Cong Jiangping Gao Kewei Ma Yajun Xiao Sheng Zhang Hongyi Jiang Weilie Hu Qiang Wei Xunbo Jin Zhichen Guan Qingyong Liu Danfeng Xu Xin Gao Yongguang Jiang Weimin Gan Guang Sun Qing Wang Yanhui Liu Jianquan Hou Liping Xie Xishuang Song Fengshuo Jin Jiafu Feng Ming Cai Zhaozhao Liang Jie Zhang Dingwei Ye Lin Qi Lulin Ma Jianzhong Shou Yuping Dai Jianyong Shao Ye Tian Shizhe Hong Tao Xu Chuize Kong Zefeng Kang Yuexin Liu Xun Qu Benkang Shi Shaobin Zheng Yi Lin Shujie Xia Dong Wei Jianbo Wu Weiling Fu Zhiping Wang Jianbo Liang | 2019 | Asian Journal of Urology2019，6，1： | 2 |

| 5 | Distribution of Organic Pesticide HCH in Jiaozhou Bay显示文摘According to the investigated data of Jiaozhou Bay in April,August,September and October of 1989,distribution,source and seasonal change of HCH in Jiaozhou Bay were analyzed. Results showed that HCH content changed during 0. 012 7-0. 069 8 μg /L in Jiaozhou Bay and was very low. Seen from HCH content,water in Jiaozhou Bay was cleaner,and HCH did not have seasonal change. Horizontal distribution of HCH showed that HCH was directly input into offshore water only by surface runoff,and there was no river input. HCH was area source and was from land. In Jiaozhou Bay,the maximum HCH was gradually becoming smaller,and input manner also changed. HCH migration changed from river input to river and surface runoff input to final surface runoff input. | Yang Dongfang Song Wenpeng Xu Zijun Geng Xiao Yang Danfeng | 2014 | Meteorological and Environmental Research2014，5，4： | 1 |

| 8 | Novel joint encoding/decoding algorithms of fountain codes for underwater acoustic communication显示文摘Fountain codes are considered to be a promising coding technique in underwater acoustic communication(UAC) which is challenged with the unique propagation features of the underwater acoustic channel and the harsh marine environment. And Luby transform(LT) codes are the first codes fully realizing the digital fountain concept. However, in conventional LT encoding/decoding algorithms, due to the imperfect coverage(IC) of input symbols and short cycles in the generator matrix, stopping sets would occur and terminate the decoding. Thus, the recovery probability is reduced,high coding overhead is required and decoding delay is increased.These issues would be disadvantages while applying LT codes in underwater acoustic communication. Aimed at solving those issues, novel encoding/decoding algorithms are proposed. First,a doping and non-uniform selecting(DNS) encoding algorithm is proposed to solve the IC and the generation of short cycles problems. And this can reduce the probability of stopping sets occur during decoding. Second, a hybrid on the fly Gaussian elimination and belief propagation(OFG-BP) decoding algorithm is designed to reduce the decoding delay and efficiently utilize the information of stopping sets. Comparisons via Monte Carlo simulation confirm that the proposed schemes could achieve better overall decoding performances in comparison with conventional schemes. | Mingshen Liang Jinjue Duan Danfeng Zhao Jiaxi Si Xiangyu Song | 2016 | Journal of Systems Engineering and Electronics2016，27，4： | 0 |
| 9 | 托瑞米芬单药及联合吉西他滨对人肺腺癌A549细胞的抑制作用(英文)显示文摘Objective: The aim of this study was to investigate the effect of toremifene on A549 human lung adenocarcinoma cells, and its sensibilization with gemcitabine, so that to provide a new clinical approach for non-small-cell lung cancer(NSCLC). Methods: A549 cells were seeded into 96-well plates and exposed to different agents(gemcitabine or gemcitabine with toremifene). The cytotoxicity of each agent was evaluated by MTT, cell cycle and apoptotic rate were detected by flow cytometry(FCM). Results: 1. By using FCM, we found A549 cells in S and G2/M phases with toremifene decreased but increased in G0/G1 phase. The higher concentration of toremifene, the more decreased was when compared with the control group. 2. FCM showed toremifene's apoptosis effect on A549 cells increased with its increasing dose. 3. By MTT, toremifene had no cytotoxic effect on A549 cells at the concentration of 5 or 2.5 μmol/L. The IC50 of gemcitabine to A549 was 34.51 μmol/L, and the combined group was 13.59 μmol/L. Conclusion: Toremifene could inhibit the growth of A549 human lung adenocarcinoma cells. Toremifene combined with gemcitabine showed significantly remarkable chemotherapy sensibilization on A549 human lung adenocarcinoma cells. | Jianing Jiang Danfeng Song Jinbo Zhao Xiuhua Sun | 2014 | The Chinese-German Journal of Clinical Oncology2014，13，2： | 0 |
| 10 | Discovering ester and ether derivatives of luminol as advanced chemiluminescence probes显示文摘A variety of luminol derivatives with N-and O-substitution have been synthesized with broad functional group tolerance. O-esterification has been demonstrated for the first time as a promising way to prepare enhanced CL reagents for sensing hemin, bloodstain and horseradish peroxidase(HRP). The most effective analogue with a deuterated acetyl group exhibited greater potential than luminol for bloodstain imaging and HRP imaging in western blotting(WB). In addition, O-etherification can greatly suppress CL signal that has been applied to design a CL probe for β-glucosidase(β-Glu). This study offers important and useful information regarding the luminol modification and shows great potential to use O-substituted analogues for enhanced CL analysis. | Fuqian Chen Ying Zhang Ting Li Danfeng Peng Zhiwen Qi Jianping Song Tao Deng Fang Liu | 2023 | Chinese Chemical Letters2023，34，3： | 0 |
