| 1 | Genetic analysis and molecular mapping of a presenescing leaf gene psll in rice (Oryza sativa L.)显示文摘A rice psl1 (presenescing leaf) mutant was obtained from a japonica variety Zhonghua 11 via radiation of 60Co-γ in M2 generation. Every leaf of the mutant began to wither after it reached the big-gest length,while the leaves of the wild variety could keep green for 25―35 d. In this study,genetic analysis and gene mapping were carried out for the mutant identified. The SSR marker analysis showed that the mutant was controlled by a single recessive gene (psl1) located on chromosome 2. Fine mapping of the psl1 locus was conducted with 34 new STS markers developed around psl1 anchored region based on the sequence diversity between Nippon-bare and 93-11. The psl1 was further mapped be-tween two STS markers,STS2-19 and STS2-26,with genetic distances of 0.43 and 0.11 cM,respectively,while cosegregated with STS2-25. A BAC contig was found to span the psl1 locus,the region being delim-ited to 48 kb. This result was very useful for cloning of the psl1 gene. | WANG dun WU Shujun ZHOU Yong ZHOU Lihui XU Jiefen HU Jing FANG Yunxia GU Minghong LIANG Guohua | 2006 | Chinese Science Bulletin2006，51，24： | 16 |
| 2 | EMTP-type Program Realization of Krylov Subspace Based Model Reduction Methods for Large-Scale Active Distribution Network显示文摘Effective model reduction methods are required to deal with new challenges in active distribution network simulations that are on a large scale and have complicated structures.In the development of advanced electromagnetic transient simulation programs,automated model reduction plays an important role.This paper proposes an automated realization algorithm for the Krylov subspace based model reduction methods of an active distribution network with which the reduced model can be automatically established according to a given threshold of reduction error.The combined state-space nodal analysis framework is employed to apply the automated model reduction algorithm in popular EMTP-type simulation programs.Simulations are performed using PSCAD and a self-developed program to show the feasibility and validity of the proposed methods. | Chengshan Wang Hao Yu Peng Li Jianzhong Wu Chengdi Ding Guanyu Song Dun Lin Feng Xing | 2015 | CSEE Journal of Power and Energy Systems2015，1，1： | 8 |
| 3 | PA1b, a plant peptide, induces intracellular [Ca^(2+)] in- crease via Ca^(2+) influx through the L-type Ca^(2+) channel and triggers secretion in pancreatic β cells显示文摘Using alginic acid to adsorb polypeptides at pH 2.7, we isolated a peptide pea albumin 1b (PA1b) from pea seeds. The PA1b is a single chain peptide consisting of 37 amino acid residues with 6 cysteines which constitutes the cystine-knot structure. Using microfluorometry and patch clamp techniques, we found that PA1b significantly elevated the intracellular calcium level ([Ca2+ ]i) and elicited membrane capacitance increase in the primary rat pancreatic β cells. The PA1b effect on [Ca2+]i elevation was abolished in the absence of extracellular Ca2+ or in the presence of L-type Ca2+ channel blocker, ni- modipine. Interestingly, we found that PA1b significantly depolarized membrane potential, which could lead to the opening of voltage-dependent L-type Ca2+ channels and influx of extracellular Ca2+, and then evoke robust secretion. In this study we identified the plant peptide PA1b which is capable of affecting the excitability and function of mammalian pancreatic β cell. | HU ZhiTao1, DUN XinPeng1, ZHANG Ming1, ZHU HongLiang1, XIE Li1, WU ZhengXing1, CHEN ZhengWang1 & XU Tao1,2 1 Joint Laboratory of Institute of Biophysics and Huazhong University of Science and Technology, Huazhong University of Science and Technology, Wuhan 430074, China 2 National Laboratory of Biomacromolecules, Institute of Biophysics, Chinese Academy of Sciences, Beijing 100101, China. | 2007 | Science China(Life Sciences)2007，50，3： | 5 |
| 4 | Campus Vibration in Nanwangshan Campus,China University of Geosciences at Wuhan Monitored by Short-Period Seismometers显示文摘Continuous seismic observations can record seismic waveforms, and ambient noise, for the purposes of earthquake researches and other applications. Here we deploy three digital seismometers(EPS-2) in and around the Nanwangshan Campus of the China University of Geosciences(Wuhan). This network was running from April 9 to May 9 of 2018. During this period, the seismometers recorded the May 4, 2018 M6.9 Hawaii earthquake. From the recorded waveforms, we could observe clearly the P and S arrivals, and the corresponding particle motions. Analysis of continuous observations of ambient noise shows obvious fluctuation of vibration intensity inside of the campus. The campus is quietest from 0 to 5 am. From 5 am on, the vibration intensity increases, and reaches the peak of entire day at 12 am. The amplitude then decreases to a very low level at 19:30 to 20:00 pm, and reaches another strong noisy time at 21:00 to 21:30 pm. After 21:30 pm, the intensity goes down slowly. We also observed seismic signals that were generated by the interaction of speed-control hump cars and ground. By taking the envelope and smooth operations, we observe different characteristics for different car speeds, which suggests that seismic monitoring approaches can be used for speed measurement of cars. This kind of small seismic network running in a real time fashion, would greatly help understanding of the sources of ambient noise at high frequency bands in interested areas. Analysis of a long-term observed dataset, and real time illustration will help to strengthen campus security and high-precision laboratory deployments, and also contribute to research atmosphere in earthquake science. | Lihui Wu Dun Wang Ziguang Lei Jing Fu Shuai Min Xianbing Xu Sarina Bao | 2020 | Journal of Earth Science2020，31，5： | 3 |

| 6 | Infl uence of nitrate concentrations on EH40 steel corrosion aff ected by coexistence of Desulfovibrio desulfuricans and Pseudomonas aeruginosa bacteria显示文摘Nitrate addition is a common bio-competitive exclusion(BCE)method to mitigate corrosion in produced water reinjection systems,which can aff ect microbial community compositions,especially nitrate and sulfate reducing bacteria,but its eff ectiveness is in controversy.We investigated the infl uence of nitrate concentrations on EH40 steel corrosion aff ected by coexistence of Desulfovibrio vulgaris and Pseudomonas aeruginosa bacteria.Results demonstrate that only mixed bacteria or nitrate had little eff ect on EH40 steel corrosion,and nitrate could accelerate the corrosion of EH40 steel through the action of microorganisms.The corrosion promotion of nitrate was dependent on its concentrations,which increased from 0 to 5 g/L and decreased from 5 to 50 g/L.These diff erences were believed to be related to the regulation of nitrate in the growth of bacteria and biofi lms.Therefore,care must be taken to BCE method with nitrate when nitrate reducing bacteria with high corrosive activity are present in the environments. | Zhihua SUN Jiajia WU Dun ZHANG Ce LI Liyang ZHU Ee LI | 2022 | Journal of Oceanology and Limnology2022，40，4： | 2 |

| 14 | A New Method to Construct Education Knowledge Graph显示文摘Learning from the Internet is becoming more and more convenient and attracting more and more people. How to obtain knowledge from massive data and construct high quality knowledge graph has become a research hot topic. This paper proposes a new method of knowledge graph construction based on crowd-sourcing. Firstly, learners build the subgraphs to acquire knowledge through the crowd-sourcing task; secondly, we put forward the fusion strategy of knowledge subgraph, in which knowledge graph is converted into the adjacency matrix, and the weight of the knowledge relation is calculated by matrix operations, thus knowledge graph is constructed. Finally, experiments conducted on an open platform show that the accuracy and integrity of proposed method of constructing knowledge graph are higher and our new method exists potential value for online learning and self-regulated learning. | Zhiyun Zheng Jianping Wu Zhenfei Wang Zhongyong Wang Liming Wang Dun Li | 2018 | 计算机教育2018，，12： | 1 |
