| 1 | 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 |
| 2 | Preliminary experimental results by the prototype of Sanya Incoherent Scatter Radar显示文摘In the past decades,the Incoherent Scatter Radar(ISR)has been demonstrated to be one of the most powerful instruments for ionosphere monitoring.The Institute of Geology and Geophysics at the Chinese Academy of Sciences was founded to build a state-ofthe-art phased-array ISR at Sanya(18.3°N,109.6°E),a low-latitude station on Hainan Island,named the Sanya ISR(SYISR).As a first step,a prototype radar system consisting of eight subarrays(SYISR-8)was built to reduce the technical risk of producing the entire large array.In this work,we have summarized the preliminary experimental results based on the SYISR-8.The amplitude and phase among 256 channels were first calibrated through an embedded internal monitoring network.The mean oscillation of the amplitude and phase after calibration were about 1 dB and 5°,respectively,which met the basic requirements.The beam directivity was confirmed by crossing screen of the International Space Station.The SYISR-8 was further used to detect the tropospheric wind profile and meteors.The derived winds were evaluated by comparison with independent radiosonde and balloon-based GPS measurements.The SYISR-8 was able to observe several typical meteor echoes,such as the meteor head echo,range-spread trail echo,and specular trail echo.These results confirmed the validity and reliability of the SYISR-8 system,thereby reducing the technical risk of producing the entire large array of the SYISR to some extent. | XinAn Yue WeiXing Wan Han Xiao LingQi Zeng ChangHai Ke BaiQi Ning Feng Ding BiQiang Zhao Lin Jin Chen Li MingYuan Li JunYi Wang HongLian Hao Ning Zhang | 2020 | Earth and Planetary Physics2020，4，6： | 3 |

| 4 | Measuring Mental Workload Using ERPs Based on FIR,ICA,and MARA显示文摘Mental workload is considered to be strongly linked to human performance,and the ability to measure it accurately is key for balancing human health and work.In this study,brain signals were elicited by mental arithmetic tasks of varying difficulty to stimulate different levels of mental workload.In addition,a finite impulse response(FIR)filter,independent component analysis(ICA),and multiple artifact rejection algorithms(MARAs)were used to filter event-related potentials(ERPs).Then,the data consisting of ERPs,subjective ratings of mental workload,and task performance,were analyzed through the use of variance and Spearman’s correlation during a simulated computer task.We found that participants responded faster and performed better in the easy task condition,followed by the medium and high-difficulty conditions,which verifies the validity of the ERP filtering.Moreover,larger P2 and P3 waveforms were evoked as the task difficulty increased,and a higher task difficulty elicited a more enhanced N300.Correlation analysis revealed a negative relationship between the amplitude of P3 and the subjective ratings,and a positive relationship between the P3 amplitude and accuracy.The results presented in this paper demonstrate that a combination of FIR,ICA,and MARA methods can filter ERPs in the non-invasive real-time measurement of workload.Additionally,frontocentral P2,N3,and parietal P3 components showed differences between genders.The proposed measurement of mental workload can be useful for real-time identification of mental states and can be applied to human-computer interaction in the future. | Yu Sun Yi Ding Junyi Jiang Vincent G.Duffy | 2022 | Computer Systems Science & Engineering2022，41，5： | 1 |
| 5 | Raman Micro-Spectroscopic Study of Sulfate Ion in the System Na_2SO_4-H_2O显示文摘This work aims to quantify sulfate ion concentrations in the system Na_2SO_4-H_2O using Raman micro-spectroscopy.Raman spectra of sodium sulfate solutions with known concentrations were collected at ambient temperature(293 K) and in the 500 cm^(_1)-4000 cm^(-1) spectral region.The results indicate that the intensity of the SO_4^(2-) band increases with increasing concentrations of sulfate ion.A linear correlation was found between the concentration of SO_4^(2-)(c) and parameter I_1,which represents the ratio of the area of the SO_4^(2-) band to that of the O-H stretching band of water(A_s/A_w):I_1=-0.00102+0.01538 c.Furthermore,we deconvoluted the O-H stretching band of water(2800 cm^(-1)-3800 cm^(-1)) at 3232 and 3430 cm^(-1) into two sub-Gaussian bands,and then defined Raman intensity of the two sub-bands as A_(Bi)(3232 cm^(-1)) and A_(B2)(3430 cm^(-1)),defined the full width of half maximum(FWHM) of the two sub-bands as W_(B1)(3232 cm^(-1)) and W_(B2)(3430 cm^(-1)).A linear correlation between the concentration of SO_4^(2-)(c) and parameter I_2,which represents the ratio of Raman intensity of SO_4^(2-)(A_s)(in 981 cm^(-1)) to(A_(B1)+A_(B2)),was also established:I_2=-0.0111+0.3653 c.However,no correlations were found between concentration of SO_4^(2-)(c) and FWHM ratios,which includes the ratio of FWHM of SO_4^(2-)(W_s) to W_(B1) W_(B2) and W_(B1+B2)(the sum of W_(B1) and W_(B2)),suggesting that FWHM is not suitable for quantitative studies of sulfate solutions with Raman spectroscopy.A comparison of Raman spectroscopic studies of mixed Na_2SO_4 and NaCI solutions with a constant SO_4^(2-) concentration and variable CI^- concentrations suggest that the I\ parameter is affected by CI^-,whereas the I_2 parameter was not.Therefore,even if the solution is not purely Na_2SO_4-H_2O,SO_4^(2-) concentrations can still be calculated from the Raman spectra if the H_2O band is deconvoluted into two sub-bands,making this method potentially applicable to analysis of natural fluid inclusions. | ZHU Dongliang ZHU Ziang PAN Junyi DING Junying NI Pei | 2015 | Acta Geologica Sinica(English Edition)2015，89，3： | 1 |
| 6 | Genome assembly and transcriptome analysis provide insights into the antischistosome mechanism of Microtus fortis显示文摘Microtus fortis is the only mammalian host that exhibits intrinsic resistance against Schistosoma japonicum infection.However,the underlying molecular mechanisms of this resistance are not yet known.Here,we perform the first de novo genome assembly of M.fortis,comprehensive gene annotation analysis,and evolution analysis.Furthermore,we compare the recovery rate of schistosomes,pathological changes,and liver transcriptomes between M.fortis and mice at different time points after infection.We observe that the time and type of immune response in M.fortis are different from those in mice.M.fortis activates immune and inflammatory responses on the 10th day post infection,such as leukocyte extravasation,antibody activation,Fc-gamma receptor-mediated phagocytosis,and the interferon signaling cascade,which play important roles in preventing the development of schistosomes.In contrast,an intense immune response occurrs in mice at the late stages of infection and could not eliminate schistosomes.Infected mice suffer severe pathological injury and continuous decreases in cell cycle,lipid metabolism,and other functions.Our findings offer new insights into the intrinsic resistance mechanism of M.fortis against schistosome infection.The genome sequence also provides the basis for future studies of other important traits in M.fortis. | Hong Li Zhen Wang Shumei Chai Xiong Bai Guohui Ding Yuanyuan Li Junyi Li Qingyu Xiao Benpeng Miao Weili Lin Jie Feng Mingyue Huang Cheng Gao Bin Li Wei Hu Jiaojiao Lin Zhiqiang Fu Jianyun Xie Yixue Li | 2020 | Journal of Genetics and Genomics2020，47，12： | 1 |
| 7 | Tightly focused longitudinal nano-interferometric field structure显示文摘In this paper,a specially designed Pancharatnam–Berry(PB)phase is used to fuse two-dimensional Airy-like beams to adjust and construct a new nano-interferometric field structure.The calculation results show that this nano-interferometric structure is highly dependent on the PB phase parameterγand the ratio of pupil radius to beam waistβ.The flexible setting of the nano-field with adjustable size,spacing and internal details can be realized.In addition,we found that the longitudinal field components always keep a clear pattern.Hence,it is expected that the longitudinal field components can be applied to each application scene separately. | LI Junyi WANG Xujian SHAN Xinzhi DING Sitong | 2023 | 自动化与仪器仪表2023，，4： | 0 |
| 8 | Network-based structure optimization method of the anti-aircraft system显示文摘The anti-aircraft system plays an irreplaceable role in modern combat. An anti-aircraft system consists of various types of functional entities interacting to destroy the hostile aircraft moving in high speed. The connecting structure of combat entities in it is of great importance for supporting the normal process of the system. In this paper, we explore the optimizing strategy of the structure of the anti-aircraft network by establishing extra communication channels between the combat entities.Firstly, the thought of combat network model(CNM) is borrowed to model the anti-aircraft system as a heterogeneous network. Secondly, the optimization objectives are determined as the survivability and the accuracy of the system. To specify these objectives, the information chain and accuracy chain are constructed based on CNM. The causal strength(CAST) logic and influence network(IN) are introduced to illustrate the establishment of the accuracy chain. Thirdly, the optimization constraints are discussed and set in three aspects: time, connection feasibility and budget. The time constraint network(TCN) is introduced to construct the timing chain and help to detect the timing consistency. Then, the process of the multi-objective optimization of the structure of the anti-aircraft system is designed.Finally, a simulation is conducted to prove the effectiveness and feasibility of the proposed method. Non-dominated sorting based genetic algorithm-Ⅱ(NSGA2) is used to solve the multiobjective optimization problem and two other algorithms including non-dominated sorting based genetic algorithm-Ⅲ(NSGA3)and strength Pareto evolutionary algorithm-Ⅱ(SPEA2) are employed as comparisons. The deciders and system builders can make the anti-aircraft system improved in the survivability and accuracy in the combat reality. | ZHAO Qingsong DING Junyi LI Jichao LI Huachao XIA Boyuan | 2023 | Journal of Systems Engineering and Electronics2023，34，2： | 0 |
| 9 | A scenario construction and similarity measurement method for navy combat search and rescue显示文摘Navy combat search and rescue(NCSAR) is an important component of the modern maritime warfare and the scenario of NCSAR is the basis for decision makers to rely on. According to the core elements in the NCSAR process, the NCSAR scenario structure is constructed from seven perspectives based on the multi-view architecture framework. According to the NCSAR scenarios evolution over time, the NCSAR scenario sequence is analyzed and modeled based on the concept lattice method. Then,the incremental construction algorithm of the NCSAR scenario sequence lattice is given. On this basis, the similarity measurement index of NCSAR scenarios is defined, and the similarity measurement model of NCSAR scenarios is proposed. Finally, the rationality of the method is verified by an example analysis. The NCSAR scenario and similarity measurement method proposed can provide scientific guidance for rapid making, dynamic adjustment and implementation of the NCSAR program, and thus improve the efficiency and effectiveness of NCSAR. | ZHAO Qingsong DING Junyi GUO Yu LIU Peng YANG Kewei | 2020 | Journal of Systems Engineering and Electronics2020，31，5： | 0 |
