( Hong-xia Cui ),( Ya-qi Wang ),( Fangfei Zhang ),( Tingting Li ) 한국인터넷정보학회 2018 KSII Transactions on Internet and Information Syst Vol.12 No.3

Aiming at motion analysis and compensation, it is essential to conduct motion detection with images. However, motion detection and tracking from low-altitude images obtained from an unmanned aerial system may pose many challenges due to degraded image quality caused by platform motion, image instability and illumination fluctuation. This research tackles these challenges by proposing a modified joint transform correlation algorithm which includes two preprocessing strategies. In spatial domain, a modified fuzzy edge detection method is proposed for preprocessing the input images. In frequency domain, to eliminate the disturbance of self-correlation items, the cross-correlation items are extracted from joint power spectrum output plane. The effectiveness and accuracy of the algorithm has been tested and evaluated by both simulation and real datasets in this research. The simulation experiments show that the proposed approach can derive satisfactory peaks of cross-correlation and achieve detection accuracy of displacement vectors with no more than 0.03pixel for image pairs with displacement smaller than 20pixels, when addition of image motion blurring in the range of 0~10pixel and 0.002variance of additive Gaussian noise. Moreover,this paper proposes quantitative analysis approach using tri-image pairs from real datasets and the experimental results show that detection accuracy can be achieved with sub-pixel level even if the sampling frequency can only attain 50 frames per second.

Combined Static and Dynamic Platform Calibration for an Aerial Multi-Camera System

( Hong-xia Cui ),( Jia-qi Liu ),( Guo-zhong Su ) 한국인터넷정보학회 2016 KSII Transactions on Internet and Information Syst Vol.10 No.6

Multi-camera systems which integrate two or more low-cost digital cameras are adopted to reach higher ground coverage and improve the base-height ratio in low altitude remote sensing. To guarantee accurate multi-camera integration, the geometric relationship among cameras must be determined through platform calibration techniques. This paper proposed a combined two-step platform calibration method. In the first step, the static platform calibration was conducted based on the stable relative orientation constraint and convergent conditions among cameras in static environments. In the second step, a dynamic platform self-calibration approach was proposed based on not only tie points but also straight lines in order to correct the small change of the relative relationship among cameras during dynamic flight. Experiments based on the proposed two-step platform calibration method were carried out with terrestrial and aerial images from a multi-camera system combined with four consumer-grade digital cameras onboard an unmanned aerial vehicle. The experimental results have shown that the proposed platform calibration approach is able to compensate the varied relative relationship during flight, acquiring the mosaicing accuracy of virtual images smaller than 0.5pixel. The proposed approach can be extended for calibrating other low-cost multi-camera system without rigorously mechanical structure.

On Environmental Ethics in China

Jian-xia Cui 성공회대학교 신학연구소 2009 Madang: Journal of Contextual Theology Vol.12 No.-

Since the implementation of the reform-and-open policy in 1978, the last thirty years has witnessed the development among Chinese scholars of a widespread discussion and deep research on such problems as the existence of ethical relations between humankind and nature, anthropocentrism and its value, the intrinsic value and rights of nature. As a result, they have formed a particular theoretical viewpoint, discipline model and questioned the consciousness of Chinese environmental ethics. China has made significant progress in theoretical studies of environmental ethics, and has especially gained remarkable achievements in absorbing, learning from and being compatible with advanced foreign cultures, grasping the history of the development of Western ethics, and keeping up with the pace of western academic study. As a result it could be said that China has played a positive role in promoting the development of its environmental ethics. However, although paying close attention to the theoretical developments of environmental ethics abroad (something which has nearly become the academic trend of China’s environmental ethics), Chinese environmental ethics has been short of its own say, its systematic theory construction and its Chinese cultural characteristics. Hence, it still does not have a say in the world circle of the environmental ethics field.

X. G. Cui,X. H. Wang,C. Y. Cui,G. C. Yin,C. D. Xia,X. N. Cheng,X. J. Xu 한국자기학회 2017 Journal of Magnetics Vol.22 No.2

To get deeper insight into the effect of intergranular additives in sintered Nd-Fe-B magnet and consequently improve the properties better, the interaction between additives (oxide, nitride, and carbide) and Nd-rich phase in the temperature range of 298.15-1400 K was analyzed thermodynamically. It can be found that the oxide additives became less stable than nitrides and carbides. Except for calcium oxide, almost all oxides could react with Nd from Nd-rich phase. To be different from oxide additives, the mechanism of nitrides and carbides was defined with various elements, either reaction with Nd from Nd-rich phase or not. The two different mechanisms would show different effects on the microstructure and hence properties of magnet. The thermodynamic analysis had a better agreement with the experimental information.

A Two-stage Stochastic Programming Model for Optimal Reactive Power Dispatch with High Penetration Level of Wind Generation

Cui, Wei,Yan, Wei,Lee, Wei-Jen,Zhao, Xia,Ren, Zhouyang,Wang, Cong The Korean Institute of Electrical Engineers 2017 Journal of Electrical Engineering & Technology Vol.12 No.1

The increasing of wind power penetration level presents challenges in classical optimal reactive power dispatch (ORPD) which is usually formulated as a deterministic optimization problem. This paper proposes a two-stage stochastic programming model for ORPD by considering the uncertainties of wind speed and load in a specified time interval. To avoid the excessive operation, the schedule of compensators will be determined in the first-stage while accounting for the costs of adjusting the compensators (CACs). Under uncertainty effects, on-load tap changer (OLTC) and generator in the second-stage will compensate the mismatch caused by the first-stage decision. The objective of the proposed model is to minimize the sum of CACs and the expected energy loss. The stochastic behavior is formulated by three-point estimate method (TPEM) to convert the stochastic programming into equivalent deterministic problem. A hybrid Genetic Algorithm-Interior Point Method is utilized to solve this large-scale mixed-integer nonlinear stochastic problem. Two case studies on IEEE 14-bus and IEEE 118-bus system are provided to illustrate the effectiveness of the proposed method.

Cui, Zhi-Wen,Xia, Ye,Ye, Yi-Wang,Jiang, Zhi-Mao,Wang, Ya-Dong,Wu, Jian-Ting,Sun, Liang,Zhao, Jun,Fa, Ping-Ping,Sun, Xiao-Juan,Gui, Yao-Ting,Cai, Zhi-Ming Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.7

The molecular mechanisms involved in the progression of clear cell renal cell carcinomas (ccRCCs) are still unclear. The aim of this study was to analyse the relationships between expression of RALYL and clinical characteristics. In 41 paired samples of ccRCCs and adjacent normal tissues, we used real-time qPCR to evaluate the expression of RALYL mRNA. RALYL protein levels were determined in 146 samples of ccRCC and 37 adjacent normal tissues by immunohistochemistry. Statistical analysis was used to explore the relationships between expression of RALYL and the clinical characteristics (gender, age, tumor size, T stage, N stage, M stage, survival times and survival outcome) in ccRCC. In addition, these patients were follow-up period 64 months (range: 4~116months) to investigate the influence on prognosis. We found significantly differences between ccRCC tissues and normal tissues (p<0.001, paired-sample t test) in mRNA levels of RALYL. Immunohistochemistry analyses in 146 ccRCC samples and 37 adjacent normal tissues showed significantly lower RALYL protein levels in ccRCC samples (${\chi}^2$-test, p<0.001), inversely correlating with tumour size (p=0.024), T stage (0.005), N stage (p<0.001) as well as M stage (p=0.019), but not age (p=0.357) and gender (p=0.348). Kaplan-Meier survival analysis demonstrated that people with lower level of RALYL expression had a poorer survival rate than those with a higher level of RALYL expression, significantly different by the log-rank test (p=0.011). Cox regression analysis indicated that RALYL expression (p=0.039), N stage (p=0.008) and distant metastasis (p<0.001) were independent prognosis factors for the overall survival of ccRCC patients. We demonstrated that the expression of RALYL was significantly low in ccRCC and correlated with a poor prognosis in a large number of clinical samples. Our findings showed that RALYL may be a potential therapeutic target as well as a poor prognostic factor.

Cui Yongzhong,Wang Weiwei,Lu Qin,Wu Hai‐Xia,Ling Xiaofei,Liu Juan,Zhang Jinwen,Chen Hang 한국곤충학회 2022 Entomological Research Vol.52 No.3

Energy supply is a major concern of human survival and development, and that concern demands new sources of renewable clean energy. Cellulose, as a renewable energy material is affected by low activity and high cost of cellulose. Studies of cellulose degrading bacterial microbiota in insect intestine have revealed that these potential microbes can be used as a rich resource of cellulose degrading strains. Here, the present study involves metagenomic sequencing of intestinal microbes of Macrotermes annandalei by Illumina PE150 and a total of 401,190 scaftigs were obtained. Open Reading frame (ORF) species annotation showed that the largest proportion of them belong to the phylum of Bacteroides, followed by Protobacteia, Firmicutes and Mucoromycota. Mapping to the CAZy database indicates that 4,539 genes encoding of glycoside hydrolase belongs to 109 distinct CAZy families. The results provide a theoretical basis for exploring new candidate bacteria for efficient cellulose degradation to obtain high cellulose resource yield.

Cui, Xiao-Bin,Peng, Hao,Li, Su,Li, Ting-Ting,Liu, Chun-Xia,Zhang, Shu-Mao,Jin, Ting-Ting,Hu, Jian-Ming,Jiang, Jin-Fang,Liang, Wei-Hua,Li, Na,Li, Li,Chen, Yun-Zhao,Li, Feng Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.22

Background: A number of studies have identified a shared susceptibility locus in phospholipase C epsilon 1 (PLCE1) for esophageal squamous cell carcinoma (ESCC) and gastric cardia adenocarcinomas (GCA). However, the results of PLCE1 expression in esophageal and gastric cancer remain inconsistent and controversial. Moreover, the effects on clinicopathological features remain undetermined. This study aimed to provide a precise quantification of the association between PLCE1 expression and the risk of ESCC and GCA through meta-analysis. Materials and Methods: Eligible studies were identified from PubMed, Wanfang Data, ISI Web of Science, and the Chinese National Knowledge Infrastructure databases. Using RevMan5.2 software, pooled odds ratios (ORs) with 95% confidence intervals (CIs) were employed to assess the association of PLCE1 expression with clinicopathological features relative to ESCC or GCA. Results: Seven articles were identified, including 761 esophageal and gastric cancer cases and 457 controls. Overall, we determined that PLCE1 expression was associated with tumor progression in both esophageal cancers (pooled OR=5.93; 95%CI=3.86 to 9.11) and gastric cancers (pooled OR=9.73; 95%CI=6.46 to 14.7). Moreover, invasion depth (pooled OR=3.62; 95%CI=2.30 to 5.70) and lymph node metastasis (pooled OR=4.21; 95%CI=2.69 to 6.59) were linked with PLCE1 expression in gastric cancer. However, no significant associations were determined between PLCE1 overexpression and the histologic grade, invasion depth, and lymph node metastasis in esophageal cancer. Conclusions: Our metaanalysis results indicated that upregulated PLCE1 is significantly associated with an increased risk of tumor progression in ESCC and GCA. Therefore, PLCE1 expression can be appropriately regarded as a promising biomarker for ESCC and GCA patients.
