| 1 | Unscented extended Kalman filter for target tracking显示文摘A new method of unscented extended Kalman filter (UEKF) for nonlinear system is presented. This new method is a combination of the unscented transformation and the extended Kalman filter (EKF). The extended Kalman filter is similar to that in a conventional EKF. However, in every running step of the EKF the unscented transformation is running, the deterministic sample is caught by unscented transformation, then posterior mean of nonlinearity is caught by propagating, but the posterior covariance of nonlinearity is caught by linearizing. The accuracy of new method is a little better than that of the unscented Kalman filter (UKF), however, the computational time of the UEKF is much less than that of the UKF. | Changyun Liu Penglang Shui Song Li | 2011 | Journal of Systems Engineering and Electronics2011，22，2： | 21 |

| 3 | The Late Pleistocene activity of the eastern part of east Kunlun fault zone and its tectonic significance显示文摘The nearly EW-trending East Kunlun fault zone is the north boundary of the Bayan Har block.The activity characteristics and the position of the eastern end of its eastward extension are of great significance to probing into the dynamic mechanism of formation of the east edge of the Tibetan Plateau,and also lay the foundation for seismic risk assessment of the fault zone.The following results are obtained by analysis based on satellite image interpretation of landforms,surface rupture survey,terrace scarp deformation survey,and terrace dating data on the eastern part of the East Kunlun fault zone:(1)the Luocha segment is a Holocene active fault,where a reverse L-shape paleoearthquake surface rupture zone of about 50 km long is located;(2)the Luocha segment is characterized by left-lateral slip movement under the compression-shear condition since the later period of the Late Pleistocene,with a rate of 7.68–9.37 mm/a and a vertical slip rate of 0.7–0.9 mm/a,which are basically in accord with the activity rate of segments on its west side.The results indicate that it is a part of eastward extension of the East Kunlun fault zone;(3)the high-speed linear horizontal slip of the nearly EW-trending East Kunlun fault zone is blocked by the South China block at east,and transforms into the vertical movement of the nearly SN-NNE trending Minjiang fault zone and the Longmenshan fault zone,and the uplift of Longmenshan and Minjiang.The area where transform of the two tectonic systems occurred confines the position of the east end;(4)Luocha segment and Maqu segment constitute the'Maqu seismic gap',so,seismic risk at Maqu segment is higher than that at Luocha segment,which should attract more attention. | ZHANG JunLong REN JinWei CHEN ChangYun FU JunDong YANG PanXin XIONG RenWei HU ChaoZhong | 2014 | Science China Earth Sciences2014，57，3： | 8 |
| 4 | Modified unscented Kalman filter using modified filter gain and variance scale factor for highly maneuvering target tracking显示文摘To improve the low tracking precision caused by lagged filter gain or imprecise state noise when the target highly maneuvers, a modified unscented Kalman filter algorithm based on the improved filter gain and adaptive scale factor of state noise is presented. In every filter process, the estimated scale factor is used to update the state noise covariance Qk, and the improved filter gain is obtained in the filter process of unscented Kalman filter(UKF)via predicted variance Pk|k-1, which is similar to the standard Kalman filter. Simulation results show that the proposed algorithm provides better accuracy and ability to adapt to the highly maneuvering target compared with the standard UKF. | Changyun Liu Penglang Shui Gang Wei Song Li | 2014 | Journal of Systems Engineering and Electronics2014，25，3： | 8 |
| 5 | Monitoring of atmospheric radionuclides from the Fukushima nuclear accident and assessing their impact on Xi'an, China显示文摘Aerosol radionuclides (131I, 134Cs, 137Cs) and gaseous radioactive xenon (133Xe) were monitored at Xi'an, China following the accident at the Fukushima nuclear power plant in March 2011. The additional annual effective dose attributable to the Fukushima emissions was much lower than the public annual effective dose from natural radiation, according to Chinese national standards. The monitoring results were compared with data from other countries as well as with the radionuclide concentrations observed in Xi'an after the Chernobyl nuclear accident in 1986. Possible transport pathways of the released radionuclides from Fukushima to Xi'an were investigated. The occurrence of an anticyclone in the Pacific Ocean region and the extended period over which the radionuclides were released made the determination transport pathways complex, but divergence in the plume and easterly flow evidently brought the initial suite of radionuclides to Xi'an. | LIU LongBo WU Shan CAO JunJi XIE Feng SHI QuanLin ZHANG ChangYun TANG HanBing HE XiaoBin ZHANG Rong CHEN LiYun WEI GuanYi ZHANG ZhiHong ZHANG JiaMei DANG HaiJun | 2013 | Chinese Science Bulletin2013，58，13： | 4 |
| 6 | PulseNet China,a model for future laboratory-based bacterial infectious disease surveillance in China显示文摘Surveillance is critical for the prevention and control of infectious disease.China’s real-time web-based infectious disease reporting system is a distinguished achievement.However,many aspects of the current China Infectious Disease Surveillance System do not yet meet the demand for timely outbreak detection and identification of emerging infectious disease.PulseNet,the national molecular typing network for foodborne disease surveillance was first established by the Centers for Disease Control and Prevention of the United States in 1995 and has proven valuable in the early detection of outbreaks and tracing the pathogen source.Since 2001,the China CDC laboratory for bacterial pathogen analysis has been a member of the PulseNet International family;and has been adapting the idea and methodology of PulseNet to develop a model for a future national laboratory-based surveillance system for all bacterial infectious disease.We summarized the development progress for the PulseNet China system and discussed it as a model for the future of China’s national laboratory-based surveillance system. | Wei Li Shan Lu Zhigang Cui Jinghua Cui Haijian Zhou Yiqing Wang Zhujun Shao Changyun Ye Biao Kan Jianguo Xu | 2012 | Frontiers of Medicine2012，6，4： | 4 |
| 7 | Evaluation of Antitumor,Immunomodulatory and Free Radical Scavenging Effects of A New Herbal Prescription Seaweed Complex Preparation显示文摘Seaweed Complex Preparation(SCP) is a clinical traditional Chinese medicine preparation which is composed of seven traditional Chinese herbs,and it has been used for treatment of lung cancer,liver cancer and digestive cancer.However,little information is available about the pharmacodynamic basis.The antitumor,immunomodulatory and free radical scavenging effects of SCP were evaluated in this study.Transplanted tumor in vivo method was used to determine the antitumor effect.The effects on splenocyte proliferation and phagocytosis of macrophages in tumor-bearing mice were measured by the MTT method and the phagocytizing cock red blood cell(CRBC) method respectively.The scavenging activities of SCP on DPPH and hydroxyl radicals in vitro were investigated.It was found that the medium-dose and high-dose of SCP could significantly inhibit the growth of transplanted hepatic tumor of murine hepatocarcinoma cell line H22,and promote proliferation of splenocytes and phagocytosis of macrophages.SCP possessed noticeable scavenging activities on DPPH and hydroxyl radicals.The antitumor effects of SCP might be achieved by improving immune system and scavenging free radicals,which is in accordance with the viewpoint of traditional Chinese medicine in promoting the body resistance and eliminating pathogenic factors for cancer treatment. | LIU Xin SHAO Changlun KONG Wenwen FANG Yuchun WANG Changyun | 2013 | Journal of Ocean University of China2013，12，3： | 3 |
| 8 | Preseismic deformation associated with the 2014 Ms7.3 Yutian earthquake derived from GPS data显示文摘Based on analysis of the GPS data during 1999-2007,2009-2011,and 2011-2013 mainly from the Crustal Motion Observation Network of China,we obtained the GPS horizontal velocity field,the GPS strain rate field,and the profiles across the southwestern segment of the Altyn Tagh Fault zone and its adjacent regions and identified the different characteristics of horizontal crustal deformation fields and profiles during different periods. The results show that,before the February 12,2014,Ms7. 3 Yutian earthquake,the laevorotation deformation along the southwestern segment of the Altyn Tagh Fault zone increased about 3. 3 mm /a during 2011-2013,relative to that in 2009-2011,and the GPS strain rate field distributed in the southeastern segment of the Altyn Tagh Fault during 2011-2013 increased obviously. These abnormal changes may be regarded as precursors to the Ms7. 3 Yutian earthquake. | Chen Changyun Chen Fuchao Zheng Zhijiang Zhu Shuang Zhang Junlong Yang Panxin | 2014 | Geodesy and Geodynamics2014，5，2： | 3 |
| 9 | Recent advances in distributed adaptive consensus control of uncertain nonlinear multi-agent systems显示文摘So far,distributed adaptive consensus problems for uncertain nonlinear multi-agent systems have not yet been extensively studied.Compared with centralised adaptive control,some new challenges need to be well addressed,for examples,(i)how to reach asymptotically consensus tracking with directed topology condition,by using totally distributed adaptive control strategies;(ii)how to ensure globally uniform boundedness of closed-loop systems while achieving leaderless consensus with semi-positive definite Laplacian matrix;(iii)how to maintain system performance while effectively reducing the communication burden among connected agents.This paper is mainly devoted to report some recent advances in distributed adaptive consensus control.Besides,some interesting research topics which are worthy of further investigation will also be discussed. | Wei Wang Jiang Long Changyun Wen Jiangshuai Huang | 2020 | Journal of Control and Decision2020，7，1： | 2 |
| 10 | Genome-wide analysis of NDR1/HIN1-like genes in pepper(Capsicum annuum L.)and functional characterization of CaNHL4 under biotic and abiotic stresses显示文摘Plant NDR1/HIN1-like(NHL)genes play an important role in triggering plant defenses in response to biotic stresses.In this study,we performed a genome-wide identification of the NHL genes in pepper(Capsicum annuum L.)and characterized the functional roles of these CaNHL genes in response to abiotic stresses and infection by different pathogens.Phylogenetic analysis revealed that CaNHLs can be classified into five distinct subgroups,with each group containing generic and specific motifs.Regulatory element analysis showed that the majority of the promoter regions of the identified CaNHLs contain jasmonic acid(JA)-responsive and salicylic acid(SA)-responsive elements,and transcriptomic analysis revealed that CaNHL genes are expressed in all the examined tissues of pepper.The CaNHL1,CaNHL4,CaNHL6,CaNHL10,CaNHL11,and CaNHL12 genes were significantly upregulated under abiotic stress as well as in response to different pathogens,such as TMV,Phytophthora capsici and Pseudomonas syringae.In addition,we found that CaNHL4 localizes to the plasma membrane.CaNHL4-silenced pepper plants display significantly increased susceptibility to TMV,Phytophthora capsici and Pseudomonas syringae,exhibiting reduced expression of JA-related and SA-related genes and reduced ROS production.However,transient overexpression of CaNHL4 in pepper increases the expression of JArelated and SA-related genes,enhances the accumulation of ROS,and inhibits the infection of these three pathogens.Collectively,for the first time,we identified the NHL genes in pepper and demonstrated that CaNHL4 is involved in the production of ROS and that it also regulates the expression of JA-related and SA-related genes in response to different pathogens,suggesting that members of the CaNHL family play an essential role in the disease resistance of pepper. | Changyun Liu Haoran Peng Xinyu Li Chaolong Liu Xing Lv Xuefeng Wei Aihong Zou Jian Zhang Guangjin Fan Guanhua Ma Lisong Ma Xianchao Sun | 2020 | Horticulture Research2020，7，1： | 2 |
| 11 | Isolation and Neuroprotective Activity of Phenolic Derivatives from the Marine-Derived Fungus Penicillium janthinellum显示文摘A new phenolic compound, 6-(2-acetyl-3,5-dihydroxybenzyl)-4-hydroxy-3-methyl-2H-pyran-2-one(1), along with other six known phenolic derivatives(2-7), were isolated from the mangrove rhizosphere fungus Penicillium janthinellum HK1-6 cultured in potato dextrose broth medium containing 30 g L^(-1) of natural sea salt. The structure of the new compound(1) was elucidated by comprehensive analysis of spectroscopic data including 1D and 2D NMR spectra. The proposed biosynthetic pathway of compound 1 was also studied in this research. Interestingly, a brominated phenolic derivative, aryl bromide(compound 8), was obtained from this fungal strain cultured in medium containing 30 g L^-1 of NaBr instead of natural sea salt. Compound 8 is proposed as a new natural product and formed through bromination of compound 7 when the fungus was cultured with NaBr. The neuroprotective effect of compound 1 on oxygen-glucose deprivation(OGD)-induced injury was investigated in rat spinal cord astrocytes. MTT assay demonstrated that compound 1 can attenuate OGD-induced cell viability loss in rat spinal cord astrocytes. | ZHENG Yaoyao CHEN Xu CHEN Lumin SHEN Li FU Xiumei CHEN Qiuxia CHEN Min WANG Changyun | 2020 | Journal of Ocean University of China2020，19，3： | 2 |
| 12 | Co- and post-seismic vertical displacements of Wenchuan Ms8.0 earthquake near Beichuan显示文摘Co-and post-seismic vertical displacements of the Wenchuan earthquake derived from two measurements in 2008 and 2010 along two partly-damaged leveling lines near the epicenter show the following features:Co-seismic displacement at Beichuan-Yingxiu fault was as large as 4.711 m near Beichuan,where the maximum observed fault offset was 5.1 m.In contrast,the observed co-seismic offset of the Qingchuan fault in Pingwu County was only 0.064 m.During 2008-2010,the post-seismic displacement rate was 5-27 mm/a near Beichuan-Yingxiu fault in Beichuan area,20.6 mm/a at Jiangyou-Guangyuan fault near Dakang,and only 0.2-1.3 mm/a at Qingchuan fault near Gucheng. | Dong Yunhong Luo Sanming Han Yueping Chen Changyun | 2011 | Geodesy and Geodynamics2011，2，2： | 2 |
| 13 | Surface Rupture and Coseismic Displacement of the M_S7.1 Yushu Earthquake显示文摘On April 14,2010,a devastating earthquake measured 7.1 on the Richter scale struck Yushu county,Qinghai Province,China.Field geological investigation and remote sensing interpretation show that this earthquake generated an inverse 'L-shaped' surface rupture zone,approximately 50km long.The surface rupture zone can be divided into three segments.Between the northern and middle segments of the surface rupture,there is a 16km-long segment,where no rupture was observed.The middle and the southern segments are arranged in a left-step manner,and there are right-step en echelon ruptures developed in the stepovers.The seismogenic structure is the Yushu fault,which is dominated by strike-slip with a small amount of thrust component.The earthquake results from the differential movements between the southern Qiangtang Block and northern Bayan Har Block.The earthquake recurrence interval is 185a^108a.Along an approximately 20km-long part of the Garzê-Yushu fault,between the southern surface rupture of Yushu MS7.1 earthquake and the 1896 earthquake,there is no surface rupture,its seismic risk needs further research. | Zhang Junlong Chen Changyun Hu Chaozhong Yang Panxin Xiong Renwei Li Zhimin Ren Jinwei | 2011 | Earthquake Research in China2011，25，2： | 2 |
