Objective： To analyze the trends of incidence rate and age at diagnosis for cervical cancer incidence in China using population-based cancer registration data from 2000 to 2014. Methods： Data were from National Central Cancer Registry of China. Crude incidence rates （CIRs）, age-specific incidence rate, age-standardized incidence rates （ASIRs）, age percentage distribution, standardized age percentage distribution, mean age at diagnosis and standardized mean age at diagnosis for cervical cancer in all areas of China, urban China and rural China were calculated separately. The world Segi＇s population was applied to remove the age structure influence. Joinpoint regression was performed to obtain average annual percent change （AAPC） and age- period-cohort analysis was used to examine the incidence trends. Results： CIRs and ASIRs for cervical cancer increased in China from 2000 to 2014. The AAPC of ASIRs in China was at 9.2% [95% confidence interval （95% CI）： 7.0%-I 1.5%, P〈0.05], and the AAPC in rural areas was relatively high. The age-specific incidence rate in groups aged 0-69 years have significantly increased over time. Groups aged 40-69 years showed the highest incidence risk, and the annual percent changes （APCs） of incidence rate in groups aged 40-59 years in urban China and groups aged 0-49 years in rural China were more than 10%. For each age group, the urban-to-rural incidence rate ratios （IRRs） got close to 1 over time. There were clear birth cohort effects in successive generations born from 1940 to 1970 in China. In rural China, the standardized mean age at diagnosis had significantly declined by 5.18 years. In China, the main peak and secondary peak of standardized age percentages appeared in the groups aged 45-49 and 40-44 years, respectively. In rural China, the main peak of standardized age percentage moved from the group aged 55-59 years to the group aged 45-49 years, and the standardized age percentages of groups aged 25-34 years also increased.

Locally repairable codes（LRCs） were proposed to reduce the repair degree in distributed storage systems. In particular, LRCs with availability are highly desirable for distributed storage systems, since this kind of codes provide the mechanism of local repair for code symbols and parallel reading of hot *** this paper, we propose four types of（n, k, r, t）;LRCs from combinatorial designs. We introduce several constructions of LRCs with strict availability and some constructions of distance-optimal LRCs with information-symbol locality. Most of our constructions in this paper are over F;, i.e., they are suitable for implementation.

Science China(Technological Sciences) 2016年第11期59卷 1730-1738页

作者： LI Han DUAN haibin Bio-inspired Autonomous Flight Systems (BAFS) Research Group Science and Technology on Aircraft Control Laboratory School of Automation Science and Electrical Engineering Beihang University

With the high focus on autonomous aerial refueling(AAR), it becomes increasingly urgent to design efficient methods or algorithms for solving the AAR problems in complicated aerial environments. A vision-based technology for AAR is developed in this paper, and five monocular and binocular visual algorithms for pose estimation of the unmanned aerial vehicles(UAVs) are adopted and verified in this AAR system. The real-time on-board vision system is also designed for precise navigation in the UAVs docking phase. A series of out-door comparative experiments for different pose estimation algorithms are conducted to verify the feasibility and accuracy of the vision algorithms in AAR.

Gaussian pigeon-inspired optimization approach to orbital spacecraft formation reconfiguration

引用

Chinese Journal of Aeronautics 2015年第1期28卷 200-205页

作者： Zhang Shujian Duan haibin School of Automation Science and Electrical Engineering Beihang University

With the rapid development of space technology, orbital spacecraft formation has received great attention from international and domestic academics and industry. Compared with a single monolithic, the orbital spacecraft formation system has many advantages. This paper presents an improved pigeon-inspired optimization（PIO） algorithm for solving the optimal formation reconfiguration problems of multiple orbital spacecraft. Considering that the uniform distribution random searching system in PIO has its own weakness, a modified PIO model adopting Gaussian strategy is presented and the detailed process is also given. Comparative experiments with basic PIO and particle swarm optimization（PSO） are conducted, and the results have verified the feasibility and effectiveness of the proposed Gaussian PIO（GPIO） in solving orbital spacecraft formation reconfiguration problems.
