Agricultural Sciences in China 2008年第5期7卷 535-541页

作者： FENG Hui WANG Wu-hong XU Na LU bo ZHANG Ting chen hong-bo College of Horticulture Shenyang Agricultural University Shenyang 110161 P.R.China College of Life Science Liaoning Normal University Dalian 116021 RR.China

Plant type characters of truss tomato were studied for exploring the inheritance of leaf angle, and providing a theoretical basis for breeding truss tomato cultivars in compact plant type. Participant truss tomato inbred lines were involved in the cross and backcross for multi-generations, and the mixed major genes plus polygene inheritance model was employed to analyze the inheritance model of leaf angle, plant width, and leaf drooping value. The inheritance of leaf angle and plant width was controlled by one pair of additive major genes plus additive-dominant polygene （D-2）. The additive effect of the major genes controlling leaf angle was 6.51, the additive effect of the polygene was 15.01, the potential ratio was 0.914, and the dominant degree was 0; the heritability of the major genes was 45.61% in B1 generation, 37.29% in B2 generation, and 47.71% in F2 generation. The additive effect of the major genes controlling plant width was 3.08, while the additive effect and dominant effect of the polygene were 3.58 and -1.59, respectively, with the potential ratio of -0.44 and 0 dominant degree; the heritability of the major genes was 23.30% in B1 generation, 20.73% in B2 generation, and 36.11% in F2 generation; leaf-drooping-value trait was controlled by one pair of negative complete dominant major genes plus additive-dominant polygene （D-4）. The additive effect of the major genes was 8.18, the dominant effect was -8.18, the additive effect in the polygene was 3.12, the dominant effect was 19.07, the potential ratio was 6.09, and the dominant degree was -1; the heritability of the polygene was 69.15% in B1 generation, 68.5% in B2 generation, and 49.57% in F2 generation. The improvement on leaf angle and plant width of 173×101 should be focused on the major genes and the selection should be made in early generations, while the improvement on leaf-drooping-value of 173×01 should be made in late generations.

Risk factors for residual tumor after resection of hepatocellular carcinoma

引用

World Journal of Gastroenterology 2011年第14期17卷 1889-1894页

作者： Xiao-hong chen bo-Heng Zhang Yin Xin Zheng-Gang Ren Jia Fan Shuang-Jian Qiu Jian Zhou Liver Cancer Institute and Zhongshan Hospital Fudan University Shanghai 20032 China

AIM:To identify the clinicopathological risk factors correlated with residual tumor in hepatocellular carcinoma (HCC) patients after resection. METHODS:From January 2001 to April 2007,766 HCC patients who had undergone resection were included in this research. Lipiodol angiography was performed within 2 mo after surgery and followed by post-Lipiodol computed tomography (CT) 4 wk later for all 766 patients to monitor tumor in the remnant liver. Tumor detected within the first 3-mo postoperative period was defined as residual tumor. Patients were divided into 2 groups:disease or disease-free within the first 3 mo after surgery. Risk factors for residual tumor were investigated among various clinicopathological variables. RESULTS:A total of 63 (8.22%) patients were found to have residual tumor after surgery. Three independent factors associated with residual tumor were identified by multivariate analysis:preoperative serum α-fetoprotein (AFP) level [odds ratio (OR) = 1.68 (95% confidence interval (CI):1.20-2.36)],tumor size [OR = 1.73 (95% CI:1.29-2.31)] and microvascular invasion [OR = 1.91 (95% CI:1.12-3.24)]. CONCLUSION:Residual tumor is related to AFP level,tumor size and microvascular invasion. Patients at high risk should undergo closer follow-up and could be candidates for multimodality therapy.

Automatically detecting auditory P300 in several trials

引用

Journal of Central South University 2015年第6期22卷 2201-2206页

作者：莫少锋汤井田陈洪波 School of Geosci and Info-physics Central South University School of Life and Environmental Science Guilin University of Electronic Technology

A method was demonstrated based on Infomax independent component analysis(Infomax ICA) for automatically extracting auditory P300 signals within several trials. A signaling equilibrium algorithm was proposed to enhance the effectiveness of the Infomax ICA decomposition. After the mixed signal was decomposed by Infomax ICA, the independent component(IC) used in auditory P300 reconstruction was automatically chosen by using the standard deviation of the fixed temporal pattern. And the result of auditory P300 was reconstructed using the selected ICs. The experimental results show that the auditory P300 can be detected automatically within five trials. The Pearson correlation coefficient between the standard signal and the signal detected using the proposed method is significantly greater than that between the standard signal and the signal detected using the average method within five trials. The wave pattern result obtained using the proposed algorithm is better and more similar to the standard signal than that obtained by the average method for the same number of trials. Therefore, the proposed method can automatically detect the effective auditory P300 within several trials.

Sino-US English Teaching 2014年第11期11卷 823-827页

作者： chen Qiang chen hong-bo Changchun University Changchun China

At present, quality education is proceeding in full swing in China. English education provided by colleges and universities of China has gone through a series of reform and gained relatively rapid development to a certain degree. English has become an international language, and most companies have listed English proficiency as an important requirement for hiring employees, which indicates that English teaching in classrooms of colleges and universities is of great importance. However, cultural conflict between teachers and students in English classes provided by colleges and universities has been gradually drawing people＇s attention and has an impact on quality of English teaching provided by colleges and universities. In this paper, the current situation of cultural conflict is introduced and several solutions for solving such cultural conflicts are put forward, which may be viewed as a reflection.

Dynamic correlative effect between urbanization and electricity consumption

引用

Ecological Economy 2015年第2期8卷 118-129页

作者： CAO Zi chen hong-bo Institute of Urban Development and Environment Chinese Academy of Social Sciences

Energy especially for rapid electricity consumption increasing is an obvious problem during the process of urbanization and economic growth. It is also an important research field to explore intrinsic regular pattern of electricity consumption and provide solving approaches. Firstly, this paper studies the relationship between electricity consumption and urbanization via GMM model by stages and regions. The results show that the most obvious stage of urbanization on electricity consumption is the stage between 1992-2000. The residents' income has an evident infl uence on electricity consumption of east region and industry also has generated stronger driving force in central and west regions. Then the paper analyzes the relationship between urbanization and electricity consumption by impulse function and gray correlation, and the variables of urbanization and industrialization both have various positive impulse effect. Estimating the gray correlation, central provinces with high population density and large shares of industry have high correlation degree in urbanization and electricity consumption.
