| 1 | Developing the Science Product Algorithm Testbed for Chinese Next-Generation Geostationary Meteorological Satellites:Fengyun-4 Series显示文摘Fengyun-4A(FY-4A), the first of the Chinese next-generation geostationary meteorological satellites, launched in2016, offers several advances over the FY-2: more spectral bands, faster imaging, and infrared hyperspectral measurements. To support the major objective of developing the prototypes of FY-4 science algorithms, two science product algorithm testbeds for imagers and sounders have been developed by the scientists in the FY-4 Algorithm Working Group(AWG). Both testbeds, written in FORTRAN and C programming languages for Linux or UNIX systems, have been tested successfully by using Intel/g compilers. Some important FY-4 science products, including cloud mask, cloud properties, and temperature profiles, have been retrieved successfully through using a proxy imager, Himawari-8/Advanced Himawari Imager(AHI), and sounder data, obtained from the Atmospheric Infra Red Sounder, thus demonstrating their robustness. In addition, in early 2016, the FY-4 AWG was developed based on the imager testbed—a near real-time processing system for Himawari-8/AHI data for use by Chinese weather forecasters.Consequently, robust and flexible science product algorithm testbeds have provided essential and productive tools for popularizing FY-4 data and developing substantial improvements in FY-4 products. | Min MIN Chunqiang WU Chuan LI Hui LIU Na XU Xiao WU Lin CHEN Fu WANG Fenglin SUN Danyu QIN Xi WANG Bo LI Zhaojun ZHENG Guangzhen CAO Lixin DONG | 2017 | Journal of Meteorological Research2017，31，4： | 35 |
| 2 | A linear ADRC-based robust high-dynamic double-loop servo system for aircraft electro-mechanical actuators显示文摘Compared with traditional hydraulic actuators, an Electro-Mechanical Actuator(EMA)is small in size and light in weight, so it has become more widely used. Aerodynamic load on aircraft control surface varies dramatically, and a change of flight environment leads to uncertainties of motor parameters. Therefore, high-dynamic response and strong anti-disturbance capability of an EMA are of great significance for aircraft rudder control and flight attitude adjustment. In order to improve dynamic response and disturbance rejection of an EMA and simplify control parameters tuning, a robust high-dynamic servo system based on Linear Active Disturbance Rejection Control(LADRC) is proposed for an EMA employing a Permanent Magnet Synchronous Motor(PMSM).Firstly, total disturbances of the EMA are analyzed, including parameter uncertainties, load variation, and static friction. A disturbance observer based on a reduced-order Extended State Observer(ESO) is designed to improve the anti-interference ability and dynamic performance. Secondly, the servo control architecture is simplified to a double-loop system, and a composite control of position and speed with acceleration feed-forward is presented to improve the EMA frequency bandwidth.Thirdly, the ideal model of the EMA is transformed into a simple cascade integral form with a disturbance observer, which makes it convenient to analyze and design the controller. Robustness performance comparisons are realized in frequency domain. Finally, simulation and experimental results have verified the effectiveness of the proposed strategy for EMAs. | Chunqiang LIU Guangzhao LUO Zhe CHEN Wencong TU Cai QIU | 2019 | Chinese Journal of Aeronautics2019，32，9： | 18 |
| 3 | Complement C3 activation regulates the production of tRNA-derived fragments Gly-tRFs and promotes alcohol-induced liver injury and steatosis显示文摘Complement is known to play a role in alcoholic fatty liver disease (AFLD), but the underlying mechanisms are poorly understood, thereby constraining the development of a rational approach for therapeutic intervention in the complement system. C3 deficiency has been shown to impart protective effects against ethanol-induced hepatic steatosis and inflammation. Here we demonstrate a protection effect in wild-type mice by treatment with CR2-Crry, a specific inhibitor of C3 activation. The expression of glycine transfer (t) RNA-derived fragments (Gly-tRFs) is upregulated in ethanol-fed mice and inhibition of Gly-tRFs in vivo decreases chronic ethanol feeding-induced hepatosteatosis without affecting inflammation. The expression of Gly-tRF was downregulated in C3-deficient or CR2-Crry-treated mice, but not in C5-deficient mice;Gly-tRF expression was restored by the C3 activation products C3a or Asp (C3a-des-Arg) via the regulation of CYP2E1. Transcriptome profiling of hepatic tissues showed that Gly-tRF inhibitors upregulate the expression of sirtuin1 (Sirt1) and subsequently affect downstream lipogenesis and β-oxidation pathways. Mechanistically, Gly-tRF interacts with AGO3 to downregulate Sirt1 expression via sequence complementarity in the 3′ UTR. Notably, the expression levels of C3d, CYP2E1 and Gly-tRF are upregulated, whereas Sirt1 is decreased in AFLD patients compared to healthy controls. Collectively, our findings suggest that C3 activation products contribute to hepatosteatosis by regulating the expression of Gly-tRF. Complement inhibition at the C3 activation step and treatment with Gly-tRF inhibitors may be potential and precise therapeutic approaches for AFLD. | Fudi Zhong Zhigao Hu Keqing Jiang Biao Lei Zhan Wu Guandou Yuan Hongliang Luo Chunqiang Dong Bo Tang Chaowen Zheng Shuai Yang Yonglian Zeng Zhenya Guo Shuiping Yu Huizhao Su Guo Zhang Xiaoqiang Qiu Stephen Tomlinson Songqing He | 2019 | Cell Research2019，29，7： | 14 |

| 5 | The Effects of Rapid Temperature Changes on HK,PK and HSP70 of Litopenaeus vannamei in Different Seasons显示文摘Activities of hexokinase(HK),pyruvate kinase(PK) and levels of HSP70 were measured to evaluate the response of Litopenaeus vannamei to rapid temperature changes under controlled laboratory conditions.Shrimps were subjected to a quick temperature change from 27℃ to 17℃ for the summer case(Cold temperature treatment),or from 17℃ to 27℃ for the winter case(Warm temperature treatment).After 0.5,1,3,6,12,24,48,and 72 h of exposure time,shrimps were sampled and prepared for further analysis.The results showed that the effect of acute temperature changes on activities of HK was significant.Patterns of variations of the two glycolytic enzymes suggested that enzymes in the glycolysis cycle could adjust their activities to meet the acute temperature change.The HSP70 level increased in both cold and warm temperature treatments,suggesting that the rapid temperature changes activated the process of body's self-protection.But the difference in expression peak of HSP70 might be related to the different body size and the higher thermal sensitivity to temperature increase than to temperature decrease of L.vannamei. | GUO Biao WANG Fang DONG Shuanglin HOU Chunqiang | 2010 | Journal of Ocean University of China2010，9，3： | 4 |
| 6 | Dynamic simulation and safety evaluation of high-speed trains meeting in open air显示文摘Dynamic responses of a carriage under excitation with the German high-speed low-interference track spectrum together with the air pressure pulse generated as high-speed trains passing each other are investigated with a multi-body dynamics method.The variations of degrees of freedom(DOFs:horizontal movement,roll angle,and yaw angle),the lateral wheel-rail force,the derailment coefficient and the rate of wheel load reduction with time when two carriages meet in open air are obtained and compared with the results of a single train travelling at specifie speeds.Results show that the rate of wheel load reduction increases with the increase of train speed and meets some safety standard at a certain speed,but exceeding the value of the rate of wheel load reduction does not necessarily mean derailment.The evaluation standard of the rate of wheel load reduction is somewhat conservative and may be loosened.The pressure pulse has significan effects on the train DOFs,and the evaluations of these safety indexes are strongly suggested in practice.The pressure pulse has a limited effect on the derailment coefficien and the lateral wheel-rail force,and,thus,their further evaluations may be not necessary. | Songyan Li Zhijun Zheng Jilin Yu Chunqiang Qian | 2016 | Acta Mechanica Sinica2016，32，2： | 3 |
| 7 | Hydrogen production via chemical looping reforming of coke oven gas显示文摘Coke oven gas(COG)is one of the most important by-products in steel industry,and the conversion of COG to value-added products has attracted much attention from both economic and environmental views.In this work,we use the chemical looping reforming technology to produce pure H_(2) from COG.A series of La1-xSrxFeO_(3)(x?0,0.2,0.3,0.4,0.5,0.6)perovskite oxides were prepared as oxygen carriers for this purpose.The reduction behaviors of La1-xSrxFeO_(3) perovskite by different reducing gases(H_(2),CO,CH4 and the mixed gases)are investigated to discuss the competition effect of different components in COG for reacting with the oxygen carriers.The results show that reduction temperatures of H_(2) and CO are much lower than that of CH4,and high temperatures(>800℃)are requested for selective oxidation of methane to syngas.The co-existence of CO and H_(2) shows weak effect on the equilibrium of methane conversion at high temperatures,but the oxidation of methane to syngas can inhibit the consumption of CO and H_(2).The doping of suitable amounts of Sr in LaFeO_(3) perovskite(e.g.,La0.5Sr0.5FeO_(3))significantly promotes the activity for selective oxidation of methane to syngas and inhibits the formation of carbon deposition,obtaining both high methane conversion in the COG oxidation step and high hydrogen yield in the water splitting step.The La0.5Sr0.5FeO_(3) shows the highest methane conversion(67.82%),hydrogen yield(3.34 mmol g^(-1))and hydrogen purity(99.85%).The hydrogen yield in water splitting step is treble as high as the hydrogen consumption in reduction step.These results reveal that chemical looping reforming of COG to produce pure H_(2) is feasible,and an O_(2)-assistant chemical looping reforming process can further improves the redox stability of oxygen carrier. | Kun Yang Zhenhua Gu Yanhui Long Shen Lin Chunqiang Lu Xing Zhu Hua Wang Kongzhai Li | 2021 | Green Energy & Environment2021，6，5： | 2 |

| 10 | Layered Mg-Al spinel supported Ce-Fe-Zr-O oxygen carriers for chemical looping reforming显示文摘A series of layered Mg-Al spinel supported Ce-Fe-Zr-O oxygen carriers were prepared for co-production of syngas and pure hydrogen via chemical looping steam reforming(CLSR).The presence of magnesium-aluminum layered double oxides(Mg Al-LDO)significantly increases the specific surface area of the mixed oxides,reduces the particle size of CeO2-based solid solution and promotes the dispersion of free Fe2O3.When reacting with methane,Mg Al-LDO supported oxygen carrier shows much lower temperature for methane oxidation than the pure CeFe-Zr-O sample,indicating enhanced low-temperature reactivity.Among different Ce-Fe-Zr-O(x)/Mg Al-LDO samples,the Ce-Fe-Zr-O(40 wt%)/Mg Al-LDO sample shows the best performance for the selective oxidation of methane to syngas and the H2 production by water splitting.After a long period of high temperature redox experiment,the Ce-Fe-Zr-O(40 wt%)/Mg Al-LDO oxygen carrier still shows high activity for syngas generation.The comparison on the morphology of the fresh and cycled oxygen carriers indicates that the Mg-Al spinel support still forms a stable skeleton structure with high dispersion of active components on the surface after the long-term cycling,which contributes to excellent redox stability of the Ce-Fe-Zr-O(40 wt%)/Mg Al-LDO oxygen carrier. | Jiangyong Yuan Yannan Zhao Haiwen Xu Chunqiang Lu Kun Yang Xing Zhu Kongzhai Li | 2020 | Chinese Journal of Chemical Engineering2020，28，10： | 1 |
| 11 | 植物生长潜力而非系统发育关系预测荒废农田土壤生物对外来和本土植物的作用显示文摘植物能够调控土壤生物群落,而后者将对后期发生的植物适合度和群落结构产生显著影响。长期种植的单一农作物能够显著调控土壤生物群落,而新近荒废农田中土壤生物如何调控外来和本土杂草定植目前还不清楚,这严重束缚了农田杂草治理能力的提升。本研究采集新近荒废的玉米地表层土壤,选取58种华中地区常见农田杂草(28种外来和30种本土植物)为对象开展实验。通过将植物种植于伽马射线灭菌或未灭菌土壤,定量评价了土壤生物对植物地上、地下和总生物量的影响,探讨了实验物种-玉米系统发育距离和土壤效应是否相关,探究了能够预测土壤效应的关键植物性状。结果发现:(i)总体而言,土壤生物显著抑制实验植物生长,表明土壤拮抗生物(如病原菌等)发挥主导作用;(ii)伴随植物生长潜力提升,土壤生物对植物的抑制作用逐渐增强,而土壤生物对实验植物的调控作用与实验物种-玉米系统发育距离无关;(iii)相对于本土植物,外来植物(尤其多年生物种)被土壤生物抑制的程度更高。这些结果表明,植物生长潜力能够有效预测土壤生物对植物生长的调控作用,而且新近荒废农田土壤生物具有抵御外来植物入侵的潜力。 | Chunqiang Wei Bingbing Jia Lunlun Gao Zhen Liu Yuming Liang Xin Zhang Xinmin Lu | 2023 | Journal of Plant Ecology2023，16，1： | 1 |

| 18 | Label-free imaging immune cells and collagen in atherosclerosis with two-photon and second harmonic generation microscopy显示文摘Atherosclerosis has been recognized as a chronic inflammation disease,in which many types of cells participate in this process,including lymphocytes,macrophages,dendritic cells(DCs),mast cells,vascular smooth muscle cells(SMCs).Developments in imaging technology provide the capability to observe cellular and tissue components and their interactions.The knowledge of the functions of immune cells and their interactions with other cell and tissue components will facilitate our discovery of biomarkers in atherosclerosis and prediction of the risk factor of rupture-prone plaques.Nonlinear optical microscopy based on two-photon excited autofluorescence and second harmonic generation(SHG)were developed to image mast cells,SMCs and collagen in plaque ex vivo using endogenous optical signals.Mast cells were imaged with two-photon tryptophan autofluorescence,SMCs were imaged with two-photon NADH auto fluorescence,and collagen were imaged with SHG.This development paves the way for further study of mast cell degranulation,and the effects of mast cell derived mediators such as induced synthesis and activation of matrix metalloproteinases(MMPs)which participate in the degradation of collagen. | Chunqiang Li Riikka K.Pastila Charles P.Lin | 2016 | Journal of Innovative Optical Health Sciences2016，9，1： | 1 |
