| 1 | Space Flight Validation of Design and Engineering of the ZDPS-1A Pico-satellite显示文摘The ZDPS-1A pico-satellites are the first satellites in China within the 1-10 kg mass range that are successfully operated on orbit. Unlike common pico-satellites, they are designed to be 'larger but stronger' with more powerful platforms and unique payloads so as to bear a better promise for real applications. Through their space flight mission, the functionality and performance of the two flight models are tested on orbit and validated to be mostly normal and in consistency with design and ground tests with only several inconforming occasions. Moreover, they have worked properly on orbit for one year so far, well exceeding their life expectancy of three months. Therefore, the space flight mission has reached all its goals, and verified that the design concept and the engineering process of the picosatellites are sufficient in allowing them the desired functionality and performance in, and the adaption to the launch procedure and the low-Earth orbit space environment. In the foreseeable future, the platform together with the design concept and the engineering process of the pico-satellites are expected to be applied to more complicated real space applications. | YANG Mu WANG Hao WU Changju WANG Chunhui DING Licong ZHENG Yangming JIN Zhonghe | 2012 | Chinese Journal of Aeronautics2012，25，5： | 5 |
| 2 | Graph-tree-based software control flow checking for COTS processors on pico-satellites显示文摘This paper proposes a generic high-performance and low-time-overhead software control flow checking solution, graph-tree-based control flow checking (GTCFC) for space-borne commercial-off-the-shelf (COTS) processors. A graph tree data structure with a topology similar to common trees is introduced to transform the control flow graphs of target programs. This together with design of IDs and signatures of its vertices and edges allows for an easy check of legality of actual branching during target program execution. As a result, the algorithm not only is capable of detecting all single and multiple branching errors with low latency and time overheads along with a linear-complexity space overhead, but also remains generic among arbitrary instruction sets and independent of any specific hardware. Tests of the algorithm using a COTS-processor-based onboard computer (OBC) of in-service ZDPS-1A pico-satellite products show that GTCFC can detect over 90% of the randomly injected and all-pattern-covering branching errors for different types of target programs, with performance and overheads consistent with the theoretical analysis; and beats well-established preeminent control flow checking algorithms in these dimensions. Furthermore, it is validated that GTCGC not only can be accommodated in pico-satellites conveniently with still sufficient system margins left, but also has the ability to minimize the risk of control flow errors being undetected in their space missions. Therefore, due to its effectiveness, efficiency, and compatibility, the GTCFC solution is ready for applications on COTS processors on pico-satellites in their real space missions. | Yang Mu Wang Hao Zheng Yangming Jin Zhonghe | 2013 | Chinese Journal of Aeronautics2013，26，2： | 1 |
| 3 | An Evaluation of the Coupling Coordination of Technological Innovation System in China’s Marine Biopharmaceutical Industry显示文摘The marine biopharmaceutical industry(MBI)has been considered as an important part of the blue economy.The high-quality development of this industry depends on the high-level coordinated development of technological innovation system(TIS).In the present study,the coupling mechanism of industrial innovation input subsystem and innovation output subsystem was analyzed for the first time.On this basis,the development level and coupling coordination level of TIS in China’s MBI during 2008-2018 were empirically evaluated with the capacity coupling coordination model.Then,the obstacle factors were diagnosed and recognized with the obstacle model.The results showed that the innovation input index fluctuated at a low level in China’s MBI.The innovation output index has basically maintained a growth trend,whereas the quality of development was not high.Although the coupling coordination level of TIS showed a positive change as mild disordered→primary coordinated→well-coordinated,the development type of innovation system has changed from the lagging output of innovation into the lagging input of innovation.Insufficient input of innovation factors remained the main obstacle to the improvement of coordination level.Based on the above analysis,suggestions were put forward from the perspectives of policy and fund guarantees to improve the coupling coordination level in China’s MBI. | FU Xiumei ZHENG Yangming LIN Chunyu WANG Ping WANG Changyun | 2023 | Journal of Ocean University of China2023，22，1： | 0 |
| 4 | Geographic range size patterns across plants and animals of Xinjiang,China显示文摘Patterns in species geographic range size are relatively well-known for vertebrates,but still poorly known for plants.Contrasts of these patterns between groups have rarely been investigated.With a detailed flora and fauna distribution database of Xinjiang,China,we used regression methods,redundancy analysis and random forests to explore the relationship of environment and body size with the geographic range size of plants,mammals and birds in Xinjiang and contrast these patterns between plants and animals.We found positive correlations between species range size and body size.The range size of plants was more influenced by water variables,while that of mammals and birds was largely influenced by temperature variables.The productivity variable,i.e.,Enhanced Vegetation Index(EVI)was far more correlated with range size than climatic variables for both plants and animals,suggesting that vegetation productivity inferred from remote sensing data may be a good predictor of species range size for both plants and animals. | LiPing Li ChunYan Zhang Eimear Nic Lughadha Tarciso CCLeão Kate Hardwick YaoMin Zheng HuaWei Wan Ming Ma Nurbay Abudusalih Ying Hai Zhen Pu JiangShan Lai ZhanFeng Shen Li Liu Tuo Wang YangMing Jiang HuiHui Zhao QingJie Liu | 2022 | Research in Cold and Arid Regions2022，14，1： | 0 |
| 5 | ModiΡed pseudo-noise code regeneration method显示文摘A modiΡed pseudo-noise(PN) code regeneration method is proposed to improve the clock tracking accuracy without impairing the code acquisition time performance.Thus,the method can meet the requirement of high accuracy ranging measurements in short time periods demanded by radio-science missions.The tracking error variance is derived by linear analysis.For some existing PN codes,which can be acquired rapidly,the tracking error variance performance of the proposed method is about 2.6 dB better than that of the JPL scheme(originally proposed by Jet Propulsion Laboratory),and about 1.5 dB better than that of the traditional double loop scheme. | Xiaojun Jin Zhonghe Jin Chaojie Zhang Jianwen Jiang Yangming Zheng | 2010 | Journal of Systems Engineering and Electronics2010，21，3： | 0 |
| 6 | Efficient inhibition of SARS-CoV-2 emerging EG.5,EG.5.1 and BA.2.86 variants by fusion inhibitor HY3000 peptide显示文摘Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)continues to pose a significant threat to the world,as it continually evolves and gives rise to multiple variants and sub-variants.Recently,the Omicron EG.5 linage,which was first detected in Indonesia on 17 February 2023,has raised concerns due to its increased prevalence and extended immune escape properties,according to the risk analysis by the World Health Organization(WHO)[1].As of 3 October 2023,EG.5 and its sub-linages have been reported in 83 countries with shared 49,008 genome sequences in GISAID database(http://gffzz25fa773688d24fb7swxwkpfuffxu66pfp.ffgz.tsg.suse.edu.cn/hcov19-variants/).EG.5 has become the dominant strain in the United States according to Centers for Disease Control and Prevention(CDC),accounting for 29.4%of SARS-CoV-2 infections(http://gffzz7e25867c50ea4228swxwkpfuffxu66pfp.ffgz.tsg.suse.edu.cn/covid-data-tracker/#variant-proportions). | Lili Wu Anqi Zheng Yangming Tang Xiaoyun Wang Yue Gao Wenwen Lei Guizhen Wu Qihui Wang George Fu Gao | 2024 | hLife2024，2，1： | 0 |
| 7 | A pan-coronavirus peptide inhibitor prevents SARS-CoV-2 infection in mice by intranasal delivery显示文摘Coronaviruses(Co Vs)have brought serious threats to humans,particularly severe acute respiratory syndrome coronavirus 2(SARS-Co V-2),which continually evolves into multiple variants.These variants,especially Omicron,reportedly escape therapeutic antibodies and vaccines,indicating an urgent need for new antivirals with pan-SARS-Co V-2 inhibitory activity.We previously reported that a peptide fusion inhibitor,P3,targeting heptad repeated-1(HR1)of SARS-Co V-2 spike(S)protein,could inhibit viral infections.Here,we further designed multiple derivatives of the P3 based on structural analysis and found that one derivative,the P315V3,showed the most efficient antiviral activity against SARS-Co V-2 variants and several other sarbecoviruses,as well as other human-Co Vs(HCo Vs).P315V3 also exhibited effective prophylactic efficacy against the SARS-Co V-2 Delta and Omicron variants in mice via intranasal administration.These results suggest that P315V3,which is in PhaseⅡclinical trial,is promising for further development as a nasal pan-SARS-Co V-2 or pan-Co Vs inhibitor to prevent or treat CoV diseases. | Lili Wu Anqi Zheng Yangming Tang Yan Chai Jiantao Chen Lin Cheng Yu Hu Jing Qu Wenwen Lei William Jun Liu Guizhen Wu Shaogui Zeng Hang Yang Qihui Wang George Fu Gao | 2023 | Science China(Life Sciences)2023，66，10： | 0 |
| 8 | Physical-Layer Key Generation Based on Multipath Channel Diversity Using Dynamic Metasurface Antennas显示文摘Physical layer key generation(PKG)technology leverages the reciprocal channel randomness to generate the shared secret keys.The low secret key capacity of the existing PKG schemes is due to the reduction in degree-of-freedom from multipath fading channels to multipath combined channels.To improve the wireless key generation rate,we propose a multipath channel diversity-based PKG scheme.Assisted by dynamic metasurface antennas(DMA),a two-stage multipath channel parameter estimation algorithm is proposed to efficiently realize super-resolution multipath parameter estimation.The proposed algorithm first estimates the angle of arrival(AOA)based on the reconfigurable radiation pattern of DMA,and then utilizes the results to design the training beamforming and receive beamforming to improve the estimation accuracy of the path gain.After multipath separation and parameter estimation,multi-dimensional independent path gains are utilized for generating secret keys.Finally,we analyze the security and complexity of the proposed scheme and give an upper bound on the secret key capacity in the high signal-to-noise ratio(SNR)region.The simulation results demonstrate that the proposed scheme can greatly improve the secret key capacity compared with the existing schemes. | Zheng Wan Yangming Lou Xiaoming Xu Jinmei Yang Wenyu Jiang Kaizhi Huang Liang Jin | 2023 | China Communications2023，20，4： | 0 |
| 9 | Red list assessments of Chinese higher plants显示文摘Based on the two most recent assessments of Chinese higher plants in 2013 and 2020,of 34,450 and 39,330 species,respectively,we analysed the threatened status of Chinese higher plants.In 2020,around 4,088(10.39%)of the assessed species in China are threatened,2,875(7.31%)Near Threatened,27,593(70.16%)not currently threatened and categorised as Least Concern and 4,752(12.08%)categorised as Data Deficient.While in 2013,3,767(10.93%)of the assessed higher plants in China are threatened,2,723(7.90%)Near Threatened,24,296(70.53%)Least Concern and 3,612(10.48%)Data Deficient.Estimates of the Red List Index in the two years show different patterns when using different weighting methods with the equal steps weighting method showing a slight decrease(0.91675-0.91495)and the extinction risk weighting method showing a slight increase(0.98792-0.98797).We inferred that China's threatened plant species were likely/relatively effectively protected.However,attention should also be given to the non-threatened species in the future as an additional strategy for their conservation,to maintain their non-threatened status. | Liping Li Haining Qin Eimear Nic Lughadha Yaomin Zheng Huawei Wan Jack Plummer Melanie-Jayne R.Howes Huiyuan Liu Yangming Jiang Tuo Wang Huihui Zhao Zhanfeng Shen Huiping Huang | 2023 | International Journal of Digital Earth2023，16，1： | 0 |
| 10 | Enhancement and recovery of photoluminescence and stability by multifunctional etching ligands treatment for perovskite nanocrystals显示文摘Perovskite nanocrystals(PNCs)have recently become promising optoelectronic materials due to their excellent photophysical properties.However,the highly dynamic binding state between ligands and the surface of PNCs has severely restricted their luminescent properties and stabilities.In this work,1,3-bisbenzyl-2-oxoimidazolidine-4,5-dicarboxylic acid(cycle acid,CA)is introduced as both an etchant and a ligand upon post-synthetic surface treatment of PNCs.By removing the imperfect octahedrons[Pb X_(6)]^(4-)and passivating the surface defects synergistically,this treatment improves photoluminescence quantum yields from 76%to 95%and enhances the stability of PNCs against polar solvent,moisture,heat,and illumination.Meanwhile,CA can effectively and instantly recover the luminescence emission for aged PNCs.As a result,the CA-Cs Pb Br_(3)PNCs and CA-Cs Pb IxBr_(3-x)PNCs are applied as color-converting layers on a blue LED chip for warm white light-emitting diodes(WLEDs)with a color coordinate of(0.41,0.40).Importantly,the CA-based WLED device exhibits superior stability in operational conditions. | Yang Zhao Haipeng Zeng Xueqing Cai Yingshan Zhou Yangming Jiang Xin Zheng Lin Li Shujing Zhang Long Luo Weixi Li Xiaoru Zhang Ranran Liu Wenxi Liang Rui Guo Xiong Li | 2023 | Journal of Energy Chemistry2023，，1： | 0 |
