1Geohazards Induced by the Lushan Ms7.0 Earthquake in Sichuan Province, Southwest China:Typical Examples, Types and Distributional Characteristics显示文摘Geohazards induced by the Lushan Ms 7.0 earthquake on April 20, 2013 mainly have four types: collapse, landslide, slope debris flow, and sand-soil liquefaction. These geohazards mainly occurred near the epicenter, on steep slopes or below cliffs in high mountain and deep valley areas, and at or near fault ends. They have no obvious relationships to active faults, but their relationships to the weathering degree and structures of rock and rock mass are obvious. Compared with the Wenchuan Ms 8.0 earthquake on May 12, 2008, the Lushan earthquake is relatively little in the impact force and the throwing amount. All of these should be related to the magnitude of this earthquake, not very large but not very little. This character of the Lushan earthquake would make some processes uncompleted so as to bring about some concealed geohazards. Finally, in order to deal with challenges presented by such conceal geohazards, some brief recommendations are put forward.ZHANG Yongshuang DONG Shuwen HOU Chuntang GUO Changbao YAO Xin LI Bin DU Jianjun ZHANG Jiagui 2013Acta Geologica Sinica(English Edition)2013,87,3:24

3Mechanical property and permeability of raw coal containing methane under unloading confining pressure显示文摘Based on domestic-developed triaxial servo-controlled seepage equipment for thermal-hydrologicalmechanical coupling of coal containing methane,an experimental study was carried out to investigate mechanical property and gas permeability of raw coal,under the situation of conventional triaxial compression and unloading confining pressure tests in different gas pressure conditions.Triaxial unloading confining pressure process was reducing confining pressure while increasing axial pressure.The research results show that,compared with the peak intensity of conventional triaxial loading,the ultimate strength of coal samples of triaxial unloading confining pressure was lower,deformation under loading was far less than unloading,dilation caused by unloading was more obvious than loading.The change trend of volumetric strain would embody change of gas permeability of coal,the permeability first reduced along with volumetric strain increase,and then raised with volume strain decrease,furthermore,the change trends of permeability of coal before and after destruction were different in the stage of decreasing volume strain due to the effect of gas pressure.When gas pressure was greater,the effective confining pressure was smaller,and the radial deformation produced by unloading was greater.When the unloading failed confining pressure difference was smaller,coal would be easier to get unstable failure.Yin Guangzhi Li Wenpu Jiang Changbao Li Minghui Li Xing Liu Hairu Zhang Qiangui 2013International Journal of Mining Science and Technology2013,23,6:9
4Overexpression of the Watermelon Ethylene Response Factor ClERF069 in Transgenic Tomato Resulted in Delayed Fruit Ripening显示文摘Watermelon fruit undergoes distinct development stages with dramatic changes during fruit ripening.To date,the molecular mechanics of watermelon ripening remain unclear.Genetic and transcriptome evidences suggested that the ethylene response factor(ERF)gene ClERF069 may be an important candidate factor affecting watermelon fruit ripening.To dissect the roles of ClERF069 in fruit ripening,structure and phylogenetic analysis were performed using the amplified full-length sequence.Normal-ripening watermelon 97103,non-ripening watermelon PI296341-FR and the RIL population were used to analyze ClERF069 expression dynamics and the correlation with fruit ripening indexs.The results indicated that ClERF069 belongs to ERF family group VI and show high homology(83%identity)to melon ERF069-like protein.ClERF069 expression in watermelon flesh was negatively correlated with fruit lycopene content and sugar content during fruit ripening progress.Further transgenic evidences indicated that overexpression of 35S:ClERF069 in tomato noticeably delayed the ripening process up to 5.2 days.Lycopene,β-carotenoid accumulation patterns were altered and ethylene production patterns in transgenic fruits was significantly delayed during fruit ripening.Taken together,watermelon ethylene response factor ClERF069 was concluded to be a negative regulator of fruit ripening.Ming Zhou Shaogui Guo Shouwei Tian Jie Zhang Yi Ren Guoyi Gong Changbao Li Haiying Zhang Yong Xu 2020Horticultural Plant Journal2020,6,4:9

6Transcriptomics and metabolomics analyses provide insights into postharvest ripening and senescence of tomato fruit under low temperature显示文摘Tomato is one of the most important vegetable crops in the world and is a model plant used to study the ripening of climacteric fleshy fruit.During the ripening process of tomato fruit,flavor and aroma metabolites,color,texture and plant hormones undergo significant changes.However,low temperatures delayed the ripening process of tomato fruit,inhibiting flavor compounds and ethylene production.Metabolomics and transcriptomics analyses of tomato fruit stored under low temperature(LT,5°C)and room temperature(RT,25°C)were carried out to investigate the effects of storage temperature on the physiological changes in tomato fruit after harvest.The results of transcriptomics changes revealed that the differentially expressed genes(DEGs)involved in tomato fruit ripening,including several kinds of transcription factors(TFs)(TCP,WRKY,MYB and bZIP),enzymes involved in cell wall metabolism[beta-galactosidase(β-GAL),pectinesterase(PE)and pectate lyase(PL),cellulose and cellulose synthase(CESA)],enzymes associated with fruit flavor and aroma[acetyltransferase(AT),malic enzyme(ME),lipoxygenase(LOX),aldehyde dehydrogenase(ALDH),alcohol dehydrogenase(ADH)and hexokinase(HK)],genes associated with heat stress protein 70 and genes involved in the production of plant hormones such as Ethylene responsive factor 1(ERF1),Auxin/indoleacetic acids protein(AUX/IAA),gibberellin regulated protein.Based on the above results,we constructed a regulatory network model of the effects of different temperatures during the fruit ripening process.According to the analysis of the metabolomics results,it was found that the contents of many metabolites in tomato fruit were greatly affected by storage temperature,including,organic acids(L-tartaric acid,a-hydroxyisobutyric acid and 4-acetamidobutyric acid),sugars(melezitose,beta-Dlactose,D-sedoheptulose 7-phosphate,2-deoxyribose 1-phosphate and raffinose)and phenols(coniferin,curcumin and feruloylputrescine).This study revealed the effects of storage temperature on postharvest tomato fruit and provided a basis for further understanding of the molecular biology and biochemistry of fruit ripening.Chunmei Bai Caie Wu Lili Ma Anzhen Fu Yanyan Zheng Jiawei Han Changbao Li Shuzhi Yuan Shufang Zheng Lipu Gao Xinhua Zhang Qing Wang Demei Meng Jinhua Zuo 2023Horticultural Plant Journal2023,9,1:3
7Several boundary identification methods of gravity data and application in Vientiane of Laos area显示文摘The authors studied the potential field boundary identification of the new technology in order to find out the possible fractures or contact zones using the following methods such as tilt derivative,horizontal derivative of tilt derivative,normalized standard deviation and normalized differential method. Combined with Euler deconvolution and small subdomain filtering,the actual data processing results show that these methods are all able to identify wider range extending fractures and obtain abundant geological information. The horizontal derivative of tilt derivative and normalized differential method have a better resolution for the small cutting fractures and lacunae in the studied area. They provide a reliable basis for study of the cutting relationship between fractures.LI Lin WU Yangang YANG Changbao HUAN Hengfei GUO Cancan 2014Global Geology2014,17,1:2

14Systemic defense signaling in tomato显示文摘The wound-inducible expression of proteinase inhibitors (PIs) genes in tomato provides a powerful model system to elucidate the signal transduction pathway of sys- temic defense response. An increasing body of evidence indi- cates that systemin and jasmonic acid (JA) work in the same signaling pathway to activate the expression of PIs and other defense-related genes. However, little is known about how systemin and JA interact to regulate cell to cell communica- tion over long distances. Genetic analysis of the systemin/JA signaling pathway in tomato plants provides a unique op-portunity to dissect the mechanism by which peptide and oxylipin signals interact to coordinate systemic expression of defense-related genes. Previously, it has been proposed that systemin is the long-distance mobile signal for systemic ex-pression of defense related genes. However, recent genetic approach provided new evidence that jasmonic acid, rather than systemin, functions as the systemic wound signal, and that the peptide systemin works to regulate the biosynthesis of JA.LI Changbao SUN Jiaqiang JIANG Hongling WU Xiaoyan LI Chuanyou 2005Chinese Science Bulletin2005,50,17:0
15Sand rice,a promising future crop for desert and marginal lands in northern China显示文摘The pioneer Amaranthaceae species sand rice(Agriophyllum squarrosum)is an annual psammophyte that is widely distributed in the deserts and sand fields of northern China.The well-balanced nutritional values,long consumption history,and extreme stress tolerance of sand rice have fascinated scientists,prompting its development as a climate-resilient crop.Sand rice has been successfully introduced and cultivated on sandy and loess lands over the past decade,while large-scale artificial planting has been carried out in the Ulan Buh and Tengger deserts.However,the yield is far below the maximum potential,as estimated by the highest yield per plant ever found in the Tengger desert during our survey of wild populations.The current domestication of sand rice relies mainly on natural selection and mutagenesis breeding.A few elite lines with modified agronomic traits,such as compact architecture,high productivity,reduced trichomes,and short plant stature,have been developed from natural populations and a chemical mutagenesis library.Breeding new cultivars and broader cultivation of sand rice in deserts and marginal lands will stimulate economic growth and diversify the food supply,especially for the area west of the Hu Huanyong Line,thus contributing to environmental sustainability in northern China.Pengshan Zhao Ruilan Ran Hong Sun Yujie Liu Xiaofeng Li Changbao Wang Xin Zhao Guoxiong Chen 2023Grassland Research2023,2,4:0
16System Design for Pose Determination of Spacecraft Using Timeof-Flight Sensors显示文摘The pose determination between nanosatellites and the cooperative spacecraft is essential for swarm in-orbit services.Timeof–flight(ToF)sensors are one of the most promising sensors to achieve the tasks.This paper presented an end-to-end assessment of how these sensors were used for pose estimation.First,an embedded system was designed based on the ToF camera with lasers as a driven light source.Gray and depth images were collected to detect and match the cooperative spacecraft in real time,obtaining the pose information.A threshold-based segmentation was proposed to find a small set of the pixels belonging to reflector markers.Only operating on the defined active pixel set reduced computational resources.Then,morphological detection combined with an edge following-based ellipse detection extracted the centroid coordinate of the circular marker,while the center-of-heart rate was calculated as the recognition condition.Next,the marker matching was completed using a deterministic annealing algorithm,obtaining two sets of 3D coordinates.A singular value decomposition(SVD)algorithm estimated the relative pose between the nanosatellite and the spacecraft.In the experiments,the pose calculated by the TOF camera reached an accuracy of 0.13 degrees and 2 mm.It accurately identified the markers and determined the pose,verifying the feasibility of the ToF camera for rendezvous and docking.Wenshan Zhu Jinzhen Mu Changbao Shao Jiaqian Hu Beichao Wang Zhongkai Wen Fei Han Shuang Li 2022Space(Science & Technology)2022,,1:0
17Application of several potential field separation methods of gravity data in Vientiane of Laos area显示文摘Gravity data observed in geophysical surveys are the sum of potential field produced by all underground inhomogeneous geological sources with different scales,different patterns and different depths. The aim of gravity exploration is mainly to extract the meaningful local anomaly from the regional gravity anomaly which is helpful to detect the deep structure and delineate the favorable area for mineral prospecting. In this paper,several anomaly separation methods are theoretically discussed,including trend analysis method,finite element method,interpolating cut method and analytic continuation method. And,these methods are applied to achieve the delineation of potash-mine deposit in Vientiane. Through experiments,analysis and comparison,the separating result of upward continuation is shown to be satisfactory,for that can separate the ore body anomaly from the background field more effectively. Further,with the combination of the geological information and gravity anomaly,it infers four rich potash zones in the study area of Vientiane which is significant for future geological work.LI Zhaohui ZHAO Qiang WU Yangang YANG Changbao ZHAO Guoxing XING Congcong 2017Global Geology2017,20,2:0

20Characterization and spatial analysis of coseismic landslides triggered by the Luding Ms 6.8 earthquake in the Xianshuihe fault zone, Southwest China显示文摘On September 5, 2022, a magnitude Ms 6.8 earthquake occurred along the Moxi fault in the southern part of the Xianshuihe fault zone located in the southeastern margin of the Tibetan Plateau,resulting in severe damage and substantial economic loss. In this study, we established a coseismic landslide database triggered by Luding Ms 6.8 earthquake, which includes 4794 landslides with a total area of 46.79 km^(2). The coseismic landslides primarily consisted of medium and small-sized landslides, characterized by shallow surface sliding. Some exhibited characteristics of high-position initiation resulted in the obstruction or partial obstruction of rivers, leading to the formation of dammed lakes. Our research found that the coseismic landslides were predominantly observed on slopes ranging from 30° to 50°, occurring at between 1000 m and 2500 m, with slope aspects varying from 90° to 180°. Landslides were also highly developed in granitic bodies that had experienced structural fracturing and strong-tomoderate weathering. Coseismic landslides concentrated within a 6 km range on both sides of the Xianshuihe and Daduhe fault zones. The area and number of coseismic landslides exhibited a negative correlation with the distance to fault lines, road networks, and river systems, as they were influenced by fault activity, road excavation, and river erosion. The coseismic landslides were mainly distributed in the southeastern region of the epicenter, exhibiting relatively concentrated patterns within the IX-degree zones such as Moxi Town, Wandong River basin, Detuo Town to Wanggangping Township. Our research findings provide important data on the coseismic landslides triggered by the Luding Ms 6.8 earthquake and reveal the spatial distribution patterns of these landslides. These findings can serve as important references for risk mitigation, reconstruction planning, and regional earthquake disaster research in the earthquake-affected area.GUO Changbao LI Caihong YANG Zhihua NI Jiawei ZHONG Ning WANG Meng YAN Yiqiu SONG Deguang ZHANG Yanan ZHANG Xianbing WU Ruian CAO Shichao SHAO Weiwei 2024Journal of Mountain Science2024,21,1:0
