| 1 | High-speed maneuvering target detection approach based on joint RFT and keystone transform显示文摘Increasing the integration time is an effective method to improve small maneuvering target detection performance in radar applications.However,range migration and Doppler spread caused by maneuvering target motion during the integration time make it difficult to improve the coherent accumulation of target's energy and detection performance.In this study,a new method based on Radon Fourier transform(RFT) and keystone transform(KT) for high-speed maneuvering target detection is proposed.The proposed algorithm utilizes second-order KT to correct the range curvature,and the improved dechirping method to compensate for the Doppler spread.RFT is then used to correct the range walk for target coherent detection.The method is capable of correcting the range migration and the time-varied Doppler frequency of the target without knowing its velocity and acceleration.The advantage of the proposed method is that it can increase the coherent integration time and improve detection performance under the condition of Doppler frequency ambiguity.Compared with the second-order RFT algorithm,the computational burden of the proposed method is greatly reduced under the premise that the two methods have similar estimation accuracy of range,velocity and acceleration.Numerical experiments demonstrate the validity of the proposed algorithm. | TIAN Jing CUI Wei SHEN Qing WEI ZiXiang WU SiLiang | 2013 | Science China(Information Sciences)2013，56，6： | 19 |
| 2 | B-doped and La_(4)NiLiO_(8)-coated Ni-rich cathode with enhanced structural and interfacial stability for lithium-ion batteries显示文摘Ni-rich layered oxides are considered promising cathodes for advanced lithium-ion batteries(LIBs)in the future,owing to their high capacity and low cost.However,the issues on structural and interfacial stability of Ni-rich cathodes still pose substantial obstacles in the practical application of advanced LIBs.Here,we employ a one-step method to synthesize a B-doped and La_(4)NiLiO_(8)-coated LiNi_(0.82)5Co_(0.115)Mn_(0.06)O_(2)(BL-1)cathode with reliable structure and interface,for the first time.The La_(4)NiLiO_(8)coating layer can prevent cathodes from electrolyte assault and facilitate Li+diffusion kinetics.Moreover,B-doping can effectively restrain the pernicious H_(2)-H_(3) phase transition and adjust the orientation of primary particles to a radial alignment,which is obstructive to the arise of microcracks induced by the change of anisotropic volume.Specifically,when tested in pouch cells,the BL-1 cathode exhibits outstanding capacity retention of 93.49%after 500 cycles at 1 C.This dual-modification strategy dramatically enhances the stability of the structure and interface for Ni-rich cathode materials,consequently accelerating the commercialization process of high-energy–density LIBs. | Lingjun Li Lizhi Fu Miao Li Chu Wang Zixiang Zhao Shangchen Xie Haichen Lin Xianwen Wu Haodong Liu Li Zhang Qiaobao Zhang Lei Tan | 2022 | Journal of Energy Chemistry2022，31，8： | 10 |
| 3 | The Distribution of Different Clades of Seneca Valley Viruses in Guangdong Province,China显示文摘Seneca Valley virus (SVV), a newly determined etiological agent of vesicular disease in swine, causes porcine idiopathic disease and occasional acute death in piglets. Recently, an increased number of SVV infection cases have been reported in the United States (US) and China, resulting in significant economic losses to the swine industry. The first identification of SVV in China was reported in Guangdong Province, a major swine producing province. The cases of SVV were continuously reported in Guangdong in 2015 and 2016. However, the spread of SVV in Guangdong in 2017 remains unknown.In this study, we determined two new SVV strains, CH-GD-2017-1 and CH-GD-2017-2, from Guangdong. The genetic analysis suggested that the two Guangdong strains showed different characteristics to previous Guangdong strains. They showed lower nucleotide similarity with strains isolated in 2015 and 2016, and were more similar to the US strains.Phylogenetic analyses indicated that the new strains were clustered in a different clade with previous Guangdong strains.We found 28 mutated amino acids in the new strains, compared with the first Guangdong strain, SVV CH-01-2015. In the geographic analysis, we found that the US and China reported more SVV cases than other countries, and most of the SVV cases were reported in east and central China—of which, Guangdong Province is one of the major epidemic regions. In conclusion, our findings indicate that SVV continued to spread in Guangdong Province in 2017, and two different clades of SVVs have emerged in this region. | Pan Chen Fan Yang Weijun Cao Huanan Liu Keshan Zhang Xiangtao Liu Zhiwen Xu Zixiang Zhu Haixue Zheng | 2018 | Virologica Sinica2018，33，5： | 7 |
| 4 | Effective Hybrid Teaching-learning-based Optimization Algorithm for Balancing Two-sided Assembly Lines with Multiple Constraints显示文摘Due to the NP-hardness of the two-sided assembly line balancing(TALB) problem, multiple constraints existing in real applications are less studied, especially when one task is involved with several constraints. In this paper, an effective hybrid algorithm is proposed to address the TALB problem with multiple constraints(TALB-MC). Considering the discrete attribute of TALB-MC and the continuous attribute of the standard teaching-learning-based optimization(TLBO) algorithm, the random-keys method is hired in task permutation representation, for the purpose of bridging the gap between them. Subsequently, a special mechanism for handling multiple constraints is developed. In the mechanism, the directions constraint of each task is ensured by the direction check and adjustment. The zoning constraints and the synchronism constraints are satisfied by teasing out the hidden correlations among constraints. The positional constraint is allowed to be violated to some extent in decoding and punished in cost function. Finally, with the TLBO seeking for the global optimum, the variable neighborhood search(VNS) is further hybridized to extend the local search space. The experimental results show that the proposed hybrid algorithm outperforms the late acceptance hill-climbing algorithm(LAHC) for TALB-MC in most cases, especially for large-size problems with multiple constraints, and demonstrates well balance between the exploration and the exploitation. This research proposes an effective and efficient algorithm for solving TALB-MC problem by hybridizing the TLBO and VNS. | TANG Qiuhua LI Zixiang ZHANG Liping FLOUDAS C A CAO Xiaojun | 2015 | Chinese Journal of Mechanical Engineering2015，28，5： | 7 |
| 5 | Function of Ca^(2+)-/calmodulin-dependent protein kinase Ⅳ in Ca^(2+)-stimulated neuronal signaling and behavior显示文摘The activity of Ca2+/calmodulin-dependent protein kinase IV(Ca MKIV) is sensitive to activity-dependent changes in the level of intracellular Ca2+.Following neuronal stimulation,the activation of Ca MKIV may trigger synaptic modifications and transcriptional responses,both of which are involved in regulating cognitive and emotional behavior.Here,we used Ca MKIV knockout(KO) neurons and mice to examine the function of Ca MKIV in Ca2+-stimulated intracellular signaling and animal behavior,respectively.Following NMDA receptor activation or membrane depolarization,the up-regulation of CREB(c AMP responsive element binding protein) and its target gene Bdnf(brain-derived neurotrophic factor) was intact in cortical neurons obtained from Ca MKIV KO mice.Ca MKIV KO mice displayed severe impairment in contextual fear memory but normal locomotor activity and anxiety level in the contextual training chamber.Although Ca MKIV KO mice showed normal memory in the standard passive avoidance task,they were defective in learning the temporal dissociative passive avoidance task.As indicated by the light/dark test and marble-burying test data,Ca MKIV KO mice showed less anxiety and normal perseveration.In the voluntary wheel-running test,Ca MKIV KO mice showed normal running time and distance but higher maximal running speed.Our results demonstrate the function of Ca MKIV in regulating different forms of fear memory,anxiety,and certain aspect of motor function. | SONG ZiXiang CHEN Qi DING Qi ZHENG Fei LI ChengWei XU LePing WANG HongBing | 2015 | Science China(Life Sciences)2015，58，1： | 6 |
| 6 | Genetic diversity,geographic differentiation and evolutionary relationship among ecotypes of Glycine max and G. soja in China显示文摘The knowledge of origin and evolution of cultivated soybeans is one of the basic issues in both biology and agronomy of the crop. In order to investigate the nuclear and cytoplasmic genetic diversity, geographic differentiation and genetic relationship among geographic ecotypes of cultivated (Glycine max) and wild (G. soja) soybeans, the allelic profiles at 60 nuclear simple-sequence repeat (nuSSR) loci and 11 chloroplastic SSR (cpSSR) loci evenly distributed on whole genome of 393 landraces and 196 wild accessions from nation-wide growing areas in China were analyzed. (i) The genetic diversity of the wild soybean was obviously larger than that of the cultivated soybean, with their nuSSR and cpSSR alleles as 1067 vs. 980 and 57 vs 44, respectively. Of the 980 nuclear alleles detected in the cultivated soybean, 377 new ones (38.5%) emerged, while of the 44 chloroplastic alleles in the cultivated soybean, seven new ones (15.9%) emerged after domestication. (ii) Among the cultivated geographic ecotypes, those from southern China, including South-Central China, Southwest China and South China possessed relatively great genetic diversity than those from northern China, while among the wild geographic ecotypes, the Middle and Lower Changjiang Valleys wild ecotype showed the highest genetic diversity. (iii) The analysis of molecular variance, association analysis between geographic grouping and molecular marker clustering and analysis of specific-present alleles of ecotypes demonstrated that the geographic differentiation of both cultivated and wild soybeans associated with their genetic differentiation, or in other words, had their relevant genetic bases. (iv) The cluster analysis of all accessions clearly showed that the wild accessions from Middle and Lower Changjiang Valleys and South-Central & Southwest China had relatively small genetic distances with all cultivated accessions. The UPGMA dendrogram among geographic ecotypes further showed that the genetic distances between all cultivated ecotypes and the Middle and Lower Changjiang Valleys wild ecotype were smaller than those with other wild ones, including their local wild counterparts. Therefore, it is inferred that the wild ancestors in southern China, especially those from Middle and Lower Changjiang Valleys might be the common ancestor of all the cultivated soybeans. | WEN ZiXiang, ZHAO TuanJie, DING YanLai & GAI JunYi Soybean Research Institute of Nanjing Agricultural University National Center for Soybean Improvement National Key Laboratory for Crop Genetics and Germplasm Enhancement, Nanjing 210095, China | 2009 | Chinese Science Bulletin2009，54，23： | 5 |
| 7 | High-throughput metagenomic analysis of petroleum-contaminated soil microbiome reveals the versatility in xenobiotic aromatics metabolism显示文摘The soil with petroleum contamination is one of the most studied soil ecosystems due to its rich microorganisms for hydrocarbon degradation and broad applications in bioremediation.However, our understanding of the genomic properties and functional traits of the soil microbiome is limited. In this study, we used high-throughput metagenomic sequencing to comprehensively study the microbial community from petroleum-contaminated soils near Tianjin Dagang oilfield in eastern China. The analysis reveals that the soil metagenome is characterized by high level of community diversity and metabolic versatility. The metageome community is predominated by γ-Proteobacteria and α-Proteobacteria, which are key players for petroleum hydrocarbon degradation. The functional study demonstrates over-represented enzyme groups and pathways involved in degradation of a broad set of xenobiotic aromatic compounds, including toluene, xylene, chlorobenzoate, aminobenzoate, DDT, methylnaphthalene, and bisphenol. A composite metabolic network is proposed for the identified pathways, thus consolidating our identification of the pathways. The overall data demonstrated the great potential of the studied soil microbiome in the xenobiotic aromatics degradation. The results not only establish a rich reservoir for novel enzyme discovery but also provide putative applications in bioremediation. | Yun-Juan Bao Zixiang Xu Yang Li Zhi Yao Jibin Sun Hui Song | 2017 | Journal of Environmental Sciences2017，29，6： | 5 |

| 10 | Cold Stress-induced Glucosyltransferase CsUGT78A15 is Involved in the Formation of Eugenol Glucoside in Camellia sinensis显示文摘Eugenol is a natural phenolic compound known for its health-promoting properties and its ability to add a floral scent to tea plants.Plant eugenol glycosides have been identified and shown to make important contributions to fruit floral quality.However,the details of their biosynthesis and metabolism in tea plants are still unknown.Here,eugenol glucoside was unambiguously identified as a native metabolite in the tea plant,and its biosynthesis was shown to be induced by low temperature treatment.Through the analysis of UGTs induced by low temperature,the glycosyltransferase CsUGT78A15 was identified in tea,and its encoded protein was shown to catalyze the glucosylation of eugenol.Vmax/Km ratios showed that eugenol was the most suitable substrate for CsUGT78A15.Sugar donor preference analysis showed that CsUGT78A15 had a higher selectivity for glucose,followed by galactose and glucuronic acid.The expression of CsUGT78A15was correlatedwith the accumulation of eugenol glucoside in different tissues and genotypes of tea.Down-regulation of CsUGT78A15 led to a decreased eugenol glucoside content under cold stress,indicating that CsUGT78A15 plays an important role in the biosynthesis of eugenol glucoside under cold stress.The identification of eugenol glucoside in the tea plant and the discovery of a cold stress-induced eugenol glucosyltransferase in tea provide the foundation for the improvement of tea flavor under cold stress and the biotechnological production of eugenol glucoside. | Mingyue Zhao Binbin Cai Jieyang Jin Na Zhang Tingting Jing Jingming Wang Yuting Pan Zixiang Zhou Yifan Zhao Yingying Feng Feng Yu Mengting Zhang Yating Li Zhonghua Liu Chuankui Song | 2020 | Horticultural Plant Journal2020，6，6： | 4 |

| 12 | 中国西南地区2007年-2011年男性乳腺癌发生率(英文)显示文摘Objective: Male breast cancer is a rare disease with an incidence of about 1% of breast cancers in USA, but relatively lack of the information of male breast cancer in China, especially in Southwest of China, led us to study its incidence trends. Methods: Chongqing is one of the biggest and the most important areas that is located in Southwest of China. There are around 31.4 million people who live in approximate 82 402.95 km2area of Chongqing. Data about breast cancer patients registered in the Center for Disease Prevention and Control of Chongqing(China) were statistically collected from 187 hospitals, about 58 hospitals in city and 129 hospitals in country, and over 6.2 million people were studied every year. It was tried to represent all the people in villages and cities in Chongqing, China. Results: The incidence of male breast cancer in Southwest of China ranged from 0.34/100 000 to 1.45/100 000 between 2007 and 2011, while the incidence of female breast cancer ranged from 15.40/100000 to 21.66/100000 at the same time. The rate of male breast cancer to female breast cancer ranged from 0.02:1 to 0.07:1, male breast cancer accounted for 1.96% to 6.5%(with the mean value of 2.9%) of breast cancers in Southwest of China from 2007 to 2010. Conclusion: In Southwest of China male breast cancer accounts for about 2.9% of breast cancers which is higher than that in United States. It is important for policy makers and health manager to seriously consider breast cancer in future plan in Southwest of China. | Liangbin Jin Linjie Lu Lingquan Kong Yang Bai Zixiang Yao Guangyan Ji Shengchun Liu Guosheng Ren Kainan Wu Hua Tang Deqiang Mao | 2013 | The Chinese-German Journal of Clinical Oncology2013，12，11： | 2 |
| 13 | Energy-aware routing for delay-sensitive underwater wireless sensor networks显示文摘The energy reduction is a challenging problem in the applications of underwater wireless sensor networks(UWSNs). The embedded battery is difficult to be replaced and it has an upper bound on its lifetime.Multihop relay is a popular method to reduce energy consumption in data transmission. The energy minimum path from source to destination in the sensor networks can be obtained through the shortest path algorithm.However, because of the node mobility, the global path planning approach is not suitable for the routing in UWSNs. It calls for an energy-efficient routing protocol for the high dynamic UWSNs. In this paper, we propose the modified energy weight routing(MEWR) protocol to deal with the energy-efficient routing of delaysensitive UWSNs. MEWR is a low flooding routing protocol. It can tolerate the node mobility in UWSNs and achieve a low end-to-end packet delay. MEWR can provide lower energy consumption than the existing low delay routing protocols through the dynamic sending power adjustment. The simulation results demonstrate the effectiveness of MEWR. | ZHANG SenLin WANG ZiXiang LIU MeiQin QIU MeiKang | 2014 | Science China(Information Sciences)2014，57，10： | 2 |
| 14 | An efficient migrating birds optimization algorithm with idle time reduction for Type-I multi-manned assembly line balancing problem显示文摘Multi-manned assembly line,which is broadly utilized to assemble high volume products such as automobiles and trucks,allows a group of workers to assemble different tasks simultaneously in a multi-manned workstation.This additional characteristic of parallel operators increases the complexity of the traditional NP-hard assembly line balancing problem.Hence,this paper formulates the Type-I multi-manned assembly line balancing problem to minimize the total number of workstations and operators,and develops an efficient migrating birds optimization algorithm embedded into an idle time reduction method.In this algorithm,a new decoding mechanism is proposed which reduces the sequence-dependent idle time by some task assignment rules;three effective neighborhoods are developed to make refinement of existing solutions in the bird improvement phases;and temperature acceptance and competitive mechanism are employed to avoid being trapped in the local optimum.Comparison experiments suggest that the new decoding and improvements are effective and the proposed algorithm outperforms the compared algorithms. | ZHANG Zikai TANG Qiuhua LI Zixiang HAN Dayong | 2021 | Journal of Systems Engineering and Electronics2021，32，2： | 2 |

| 20 | Foot-and-Mouth Disease Virus Inhibits RIP2 Protein Expression to Promote Viral Replication显示文摘Receptors interaction protein 2(RIP2)is a specific adaptor molecule in the downstream of NOD2.The role of RIP2 during foot-and-mouth disease virus(FMDV)infection remains unknown.Here,our results showed that RIP2 inhibited FMDV replication and played an important role in the activation of IFN-βand NF-κB signal pathways during FMDV infection.FMDV infection triggered RIP2 transcription,while it reduced the expression of RIP2 protein.Detailed analysis showed that FMDV 2B,2C,3C^(pro),and L^(pro) proteins were responsible for inducing the reduction of RIP2 protein.3C^(pro) and L^(pro) are viral proteinases that can induce the cleavage or reduction of many host proteins and block host protein synthesis.The carboxyl terminal 105-C114 and 135-C144 regions of 2B were essential for reduction of RIP2.Our results also showed that the N terminal 1-61 region of 2C were essential for the reduction of RIP2.The 2C-induced reduction of RIP2 was dependent on inducing the reduction of poly(A)-binding protein 1(PABPC1).The interaction between RIP2 and 2C was observed in the context of viral infection,and the residues 1-61 were required for the interaction.These data clarify novel mechanisms of reduction of RIP2 mediated by FMDV. | Huisheng Liu Qiao Xue Zixiang Zhu Fan Yang Weijun Cao Xiangtao Liu Haixue Zheng | 2021 | Virologica Sinica2021，36，4： | 1 |
