| 2 | Major accident analysis and prevention of coal mines in China from the year of 1949 to 2009显示文摘From the year of 1949 to the present, the China national coal output has been increasing quickly and became first in the world in 2009. But at the same time, major coal mining accidents still exist nowadays. In order to review the overall situation and provide information on major accidents of coal mines in China, we investigated 26 major coal mining accidents in China between the years of 1949 and 2009 through statistical methods, each of which led to more than 100 fatalities. Statistical characteristics about accident-related factors such as time, death toll, accident reasons, characters and nature of enterprise were analyzed. And some special conclusions have been achieved. For example, although we have made great progress, the safety situation in China coal mining industry is still serious, and the reasons for the mining accidents are all human errors which are not inevitable. Such results may be helpful to prevent major accidents in coal mines. Moreso, based on both the knowledge of other countries which have good safety situation nowadays and the safety management situation of China, we made suggestion on safety management of China coal mining. In conclusion, countermeasures were proposed in accordance with the results of statistical studies and the analyses of problems existed in coal mines, including the perfec- tion of safety supervision organization, the establishment of cooperating agency among government, coal mines and workers, the perfection of safety rules and regulations, the improvement of safety investment, the enhancement of safety training, the development of safety technique, and the development of emer- gency rescue technique and equipment. | Wu Lirong Jiang Zhongan Cheng Weimin Zuo Xiuwei Lv Dawei Yao Yujing | 2011 | Mining Science and Technology2011，21，5： | 12 |
| 3 | The net primary productivity of Mid-Jurassic peatland and its control factors: Evidenced by the Ordos Basin显示文摘Using the large-scale thick 4# coal seam from the Mid-Jurassic in the southern Ordos Basin as an example, this paper studied the net primary productivity(NPP) level of the Mid-Jurassic peatland, and discussed its control factors. Geophysical logging signals were used for a spectrum analysis to obtain the Milankovitch cycle parameters in coal seam. These were then used to calculate the accumulation rate of the residual carbon in 4# coal seam. The carbon loss can be calculated according to the density and residual carbon content of 4# coal seam. Then, the total carbon accumulation rate of the peatland was further derived, and the NPP of peatland was determined. The results show that the NPP of MidJurassic peatland is higher than that of Holocene at the same latitude. Comprehensive analysis indicates that the temperature, carbon dioxide and oxygen levels in atmosphere are the main control factors of the NPP of Mid-Jurassic peatland. | Wang Dongdong Yan Zhiming Liu Haiyan Lv Dawei Hou Yijun | 2018 | International Journal of Mining Science and Technology2018，28，2： | 7 |

| 5 | Enhanced production of seed oil with improved fatty acid composition by overexpressing NAD^(+)-dependent glycerol-3-phosphate dehydrogenase in soybean显示文摘There is growing interest in expanding the production of soybean oils(mainly triacylglycerol, or TAG) to meet rising feed demand and address global energy concerns. We report that a plastidlocalized glycerol-3-phosphate dehydrogenase(GPDH), encoded by GmGPDHp1 gene, catalyzes the formation of glycerol-3-phosphate(G3 P), an obligate substrate required for TAG biosynthesis.Overexpression of GmGPDHp1 increases soybean seed oil content with high levels of unsaturated fatty acids(FAs), especially oleic acid(C18:1), without detectably affecting growth or seed protein content or seed weight. Based on the lipidomic analyses, we found that the increase in G3 P content led to an elevated diacylglycerol(DAG) pool, in which the Kennedy pathwayderived DAG was mostly increased, followed by PC-derived DAG, thereby promoting the synthesis of TAG containing relatively high proportion of C18:1. The increased G3 P levels induced several transcriptional alterations of genes involved in the glycerolipid pathways. In particular, genes encoding the enzymes responsible for de novo glycerolipid synthesis were largely upregulated in the transgenic lines, in-line with the identified biochemical phenotype. These results reveal a key role for GmGPDHp1-mediated G3 P metabolism in enhancing TAG synthesis and demonstrate a strategy to modify the FA compositions of soybean oils for improved nutrition and biofuel. | Ying Zhao Pan Cao Yifan Cui Dongxu Liu Jiapeng Li Yabin Zhao Siqi Yang Bo Zhang Runnan Zhou Minghao Sun Xuetian Guo Mingliang Yang Dawei Xin Zhanguo Zhang Xin Li Chen Lv Chunyan Liu Zhaoming Qi Jingyu Xu Xiaoxia Wu Qingshan Chen | 2021 | Journal of Integrative Plant Biology2021，63，6： | 4 |
| 6 | The Genetic Mechanism of Inertinite in the Middle Jurassic Inertinite- Rich Coal Seams of the Southern Ordos Basin显示文摘also an important geological information carrier of coal forming environments.In the southern section of the Ordos Basin,the No.4 inertinite-rich coal seam of the Middle Jurassic Yan’an Formation in the Binchang Coal field was selected as an example to study the genetic mechanism of the inertinite.In this study,the results obtained from experimental tests of coal rock,including principal and trace elements,stable carbon isotopes,scanning electron microscopy,inertinite reflectance,sporopollen and free radical retorting methods,were analyzed.Then,the findings were combined with the previous understanding of the oxygen content in the atmosphere and ground fire characteristics,in order to discuss the genesis mechanism of inertinite in the No.4 coal seam.The obtained research results were as follows:(1)During the coal forming period of the No.4 coal seam,the overall climate had been relatively dry.There were four relatively dry-wet climate cycles in the No.4 coal seam,which were controlled by the eccentricity astronomical period.The inertinite content were relatively high during the dry periods;(2)The temperature range suitable for microorganism activities during the oxidation processes was between 0 and 80℃.The simulation results of the free radical concentrations showed that the maximum temperature of fusain in the No.4 coal seam during the process of coalification had not exceeded 300℃,which was significantly higher than the temperature range of microorganism activities.Therefore,these were not conducive to the activities of microorganism and formation of inertinite during the coal-forming period;(3)The genesis temperature of the inertinite in the No.4 coal seam was calculated according to the reflectance of the inertinite,which was lower than 400℃.This result supported the cause of wildfire of the inertinite and reflected that the type of wildfire was mainly ground fire,along with partially surface fire.Moreover,the paleogeographic location,climatic conditions,atmospheric oxygen concentration,etc.of the study area showed that the conditions for wildfire events were in fact available;(4)There were dense and scattered fusinite observed in the No.4 coal seam,and the thickness of cell walls were found to differ.It was speculated that this was related to the type of wildfire,combustion temperatures,combustion timeframes,and different initial conditions of the burned objects during the coal forming periods. | Dongdong Wang Qiang Mao Guoqi Dong Shipeng Yang Dawei Lv Lusheng Yin | 2019 | Journal of Geological Research2019，1，3： | 3 |

| 8 | Light Intensity Affects Chlorophyll Synthesis During Greening Process by Metabolite Signal from Mitochondrial Alternative Oxidase in Arabidopsis显示文摘Although mitochondrial alternative oxidase(AOX)has been proposed to play essential roles in high light stress tolerance,the effects of AOX on chlorophyll synthesis are unclear.Previous studies indicated that during greening,chlorophyll accumulation was largely delayed in plants whose mitochondrial cyanide-resistant respiration was inhibited by knocking out nuclear encoded AOX gene.Here we show that this delay of chlorophyll accumulation was more significant under high light condition.Inhibition of cyanide-resistant respiration was also accompanied by the increase of plastid NADPH/NADP^+ratio,especially under high light treatment which subsequently blocked the import of multiple plastidial proteins,such as some components of the photosynthetic electron transport chain,the Calvin-Benson cycle enzymes and malate/oxaloacetate shuttle components.Over expression of AOXla rescued the aoxla mutant phenotype,including the chlorophyll accumulation during greening and plastidial protein import.It thus suggests that light intensity affects chlorophyll synthesis during greening process by a metabolic signal,the AOX-derived plastidial NADPH/NADP^+ratio change.And our results thus revealed a molecular mechanism of chloroplast-mitochondria interactions. | ZHANG Dawei YUAN Shu 徐飞 ZHU Feng YUAN Ming YE Huaxun GUO Hongqing LV Xin YIN Yanhai 林宏辉 | 2015 | 武汉生物工程学院学报2015，，3： | 2 |
| 9 | Charge density wave and weak Kondo effect in a Dirac semimetal CeSbTe显示文摘Using angle-resolved photoemission spectroscopy(ARPES) and low-energy electron diffraction(LEED), together with densityfunctional theory(DFT) calculation, we report the formation of charge density wave(CDW) and its interplay with the Kondo effect and topological states in CeSbTe. The observed Fermi surface(FS) exhibits parallel segments that can be well connected by the observed CDWordering vector, indicating that the CDWorder is driven by the electron-phonon coupling(EPC) as a result of the nested FS. The CDW gap is large(~0.3 eV) and momentum-dependent, which naturally explains the robust CDWorder up to high temperatures. The gap opening leads to a reduced density of states(DOS) near the Fermi level(EF), which correspondingly suppresses the many-body Kondo effect, leading to very localized 4 f electrons at 20 K and above. The topological Dirac cone at the X point is found to remain gapless inside the CDW phase. Our results provide evidence for the competition between CDWand the Kondo effect in a Kondo lattice system. The robust CDWorder in CeSbTe and related compounds provide an opportunity to search for the long-sought-after axionic insulator. | Peng Li BaiJiang Lv Yuan Fang Wei Guo ZhongZheng Wu Yi Wu DaWei Shen YueFeng Nie Luca Petaccia Chao Cao Zhu-An Xu Yang Liu | 2021 | Science China(Physics,Mechanics & Astronomy)2021，64，3： | 1 |

| 12 | Geochemistry,petrogenesis and tectonic significance of the late Triassic A-type granite in Fujian,South China显示文摘The late Permian–Triassic granites in southeastern China have important tectonic significance for the evolution of South China. Here, we present the detailed geochronological, geochemical and petrological analyses for the Jinlongyan(JLY) granite in northwest Fujian Province, southeast China. LA–ICP–MS zircon U–Pb dating yielded a weighted average ^(206)Pb/^(238)U age of 224.1 ±3.3 Ma. The granite is mainly comprised of K-feldspar,plagioclase, quartz, biotite and minor amphibole. It is characterized by enrichments in Rb, Th, REEs(total REE = 295.1–694.3 ppm), and HFSEs(e.g., Zr = 289–520 ppm, Hf = 9.3–15.0 ppm, Y = 36.2–68.2 ppm) but depletions in Ba, Sr, Eu and Ti. The granite is metaluminous to weakly peraluminous and show a clear A-type granite geochemical signature with high SiO_2(70.89 wt%–75.76 wt%), total alkalis(Na_2O + K_2O = 7.51 wt%–8.72 wt%), Ga/Al ratios(10000 Ga/Al = 2.72–3.43). Insitu zircon Hf isotope analysis shows their eHf(t) values ranging from-7.2 to-3.2, with Mesoproterozoic T2DM ages(1308–1525 Ma). Whole-rock Nd isotope data show their eNd(t) values in the range of-9.5 to-9.1 and yield paleoproterozoic TDMages(1606–1985 Ma). These characteristics indicate that the JLY A-type granite magma was formed by the partial melting of Meso-Paleoproterozoic crust rocks in the Cathaysia Block. Our study of the JLY A-type granite, together with other Triassic A-type granitesin South China, defines an extensional environment in the late Triassic which probably was caused by the collision of the South China Block with Indochina Block. | Dawei Cai Jingyu Zhao Yong Tang Hui Zhang Yunlong Liu Zhenghang Lv | 2017 | Acta Geochimica2017，36，2： | 1 |
| 13 | Molecular dynamics simulation of effects of nanoparticles on frictional heating and tribological properties at various temperatures显示文摘The temperature of a friction pair exerts considerable influence on the tribological behavior of a system.In two cases,one with and the other without Cu(copper)nanoparticles,the temperature increase in friction pairs caused by frictional heating and its tribological properties at various temperatures are studied by using the molecular dynamics approach.The results show that temperature distribution and surface abrasion are significantly improved by the presence of Cu nanoparticles.This is one of the reasons for the improvements in tribological properties achieved in the presence of nanoparticles.The temperature and range of influence of frictional heating for the model without nanoparticles are significantly increased with the increase in the sliding velocity;however,in the model with nanoparticles,the temperature gradient is confined to the area near the Cu film.With an increase in the temperature of the friction pair,the improvement in anti-wear properties associated with the presence of Cu nanoparticles becomes more significant. | Chengzhi HU Jizu LV Minli BAI Xiaoliang ZHANG Dawei TANG | 2020 | Friction2020，8，3： | 1 |
| 14 | Clinical practice guideline for body composition assessment based on upper abdominal magnetic resonance images annotated using artificial intelligence显示文摘Introduction Upper abdominal magnetic resonance(MR)imaging is appropriate for body composition analysis.111 Especially for individuals with obesity,it is of great value to quantify the hepatic proton density fat fraction(PDFF)and the amount of abdominal adipose tissue during clinical evaluation and for research on obesity-related risks.Analytical results may be used to determine the optimal choice of surgical procedure and evaluate treatment outcomes.Multiple artificial intelligence(Al)algorithms and systems have been developed for the automated measurement of body composition.The basis of Al development and application is to have uniform standards for clinical data acquisition and management.The uneven quality ofMR images is one ofthe major obstacles to Al system development and analytical results.A standardized process of MR scanning and clinical data management is urgently needed. | Han Lv Mengyi Li Zhenchang Wang Dawei Yang Hui Xu Juan Li Yang Liu Di Cao Yawen Liu Xinru Wu He Jin Peng Zhang Liqin Zhao Rixing Bai Yunlong Yue Bin Li Nengwei Zhang Mingzhu Zou Jinghai Song Weibin Yu Pin Zhang Weijun Tang Qiyuan Yao Liheng Liu Hui Yang Zhenghan Yang Zhongtao Zhang National Clinical Research Center for Digestive Diseases in Beijing Friendship Hospital,Capital Medical University Beijing Quality Control and Improvement Center of Medical Imaging National Health Commission Capacity Building and Continuing Education Center,Chinese College of Metabolic and Bariatric Surgeons Beijing Quality Control and Improvement Center of Metabolic and Bariatric Surgery | 2022 | Chinese Medical Journal2022，，6： | 1 |

| 16 | Effects of Melatonin on Growth,Physiology and Gene Expression in Rice Seedlings Under Cadmium Stress显示文摘Melatonin(MLT)is a hormonal substance found in many organisms and can improve plant stress resistance.In this study,the japonica rice variety Y32 and indica rice variety NJ6 were cultivated in hydroponics under different concentrations of CdCl2 at the two-leaf stage.The growth,physiological and biochemical responses of the seedlings and the expression of cadmium(Cd)-related genes under exogenous melatonin(MLT)treatment were assessed.The results indicated that Cd stress destroyed the dynamic balance between reactive oxygen species(ROS)production and removal,resulting in ROS accumulation,membrane lipid peroxidation,and impaired growth and development.Following the application of exogenous MLT to rice seedlings,increases in plant biomass including both underground and above-ground areas were observed.MLT also scavenged the inhibition of superoxide dismutase(SOD)and peroxidase(POD)in a concentration dependent manner in response to Cd stress.Catalase(CAT)activity and malondialdehyde(MDA)expression also decreased following MLT treatment.Amongst the six Cd-related genes assessed,five genes were downregulated and one was up-regulated in response to MLT treatment.Taken together,these data demonstrate that MLT improves the resilience of rice seedlings at the biochemical,physiological,and molecular levels,and diminishes the damage caused by Cd stress. | Xiachen Lv Yunxia Fang Lantian Zhang Weiyi Zhang Ling Xu Jingjin Han Bailing Jin Xian Zhang Xiaoqin Zhang Dawei Xue | 2019 | Phyton-International Journal of Experimental Botany2019，88，2： | 1 |
| 17 | Managed grassland alters soil N dynamics and N2O emissions in temperate steppe显示文摘Reclamation of degraded grasslands as managed grasslands has been increasingly accelerated in recent years in China. Land use change affects soil nitrogen(N) dynamics and nitrous oxide(N_2O) emissions. However, it remains unclear how large-scale grassland reclamation will impact the grassland ecosystem as a whole. Here, we investigated the effects of the conversion from native to managed grasslands on soil N dynamics and N_2O emissions by field experiments in Hulunber in northern China. Soil(0–10 cm), nitrate(NO_3^-),ammonium(NH_4^+), and microbial N were measured in plots in a temperate steppe(Leymus chinensis grassland) and two managed grasslands(Medicago sativa and Bromus inermis grasslands) in 2011 and 2012. The results showed conversion of L. chinensis grassland to M.sativa or B. inermis grasslands decreased concentrations of NO_3~–-N, but did not change NH_4~–N . Soil microbial N was slightly decreased by the conversion of L. chinensis grassland to M.sativa, but increased by the conversion to B. inermis. The conversion of L. chinensis grassland to M. sativa(i.e., a legume grass) increased N_2O emissions by 26.2%, while the conversion to the B. inermis(i.e., a non-legume grass) reduced N_2O emissions by 33.1%. The conversion from native to managed grasslands caused large created variations in soil NO?3^-+–N and NH_4~–N concentrations. Net N mineralization rates did not change significantly in growing season or vegetation type, but to net nitrification rate. These results provide evidence on how reclamation may impact the grassland ecosystem in terms of N dynamics and N_2O emissions. | Lijun Xu Xingliang Xu Xuejuan Tang Xiaoping Xin Liming Ye Guixia Yang Huajun Tang Shijie Lv Dawei Xu Zhao Zhang | 2018 | Journal of Environmental Sciences2018，30，4： | 1 |

| 19 | Synthesis, Characterization, and Antifungal Evaluation of Thiolactomycin Derivatives显示文摘5-Substituted benzylidene 3-acylthiotetronic acids are antifungal.A series of 3-acylthiotetronic acid derivatives with varying substitutions at the 5-position were designed,synthesized,and characterized,based on the binding pose of 3-acyl thiolactone with the protein C171Q KasA.Fungicidal activities of these compounds were screened against Valsa Mali,Curvularia lunata,Fusarium graminearum,and Fusarium oxysporum f.sp.lycopersici.Most target compounds exhibited excellent fungicidal activities against target fungi at the concentration of 50μg·mL-1.Compounds 11c and 11i displayed the highest activity with a broad spectrum.The median effective concentration(EC50)values of 11c and 11i were 1.9–10.7 and 3.1–7.8μg·mL-1,respectively,against the tested fungi,while the EC50 values of the fungicides azoxystrobin,carbendazim,and fluopyram were respectively 0.30,4.22,and>50μg·mL-1 against V.Mali;6.7,41.7,and 0.18μg·mL-1 against C.lunata;22.4,0.42,and 0.43μg·mL-1 against F.graminearum;and 4.3,0.12,and>50μg·mL-1 against F.oxysporum f.sp.lycopersici.The structures and activities of the target compounds against C.lunata were analyzed to obtain a statistically significant comparative molecular field analysis(CoMFA)model with high prediction abilities(q2=0.9816,r2=0.8060),and its reliability was verified.The different substituents on the benzylidene at the 5-position had significant effects on the activity,while the introduction of a halogen atom at the benzene ring of benzylidene was able to improve the activity against the tested fungi. | Pei Lv Yiliang Chen Dawei Wang Xiangwei Wu Qing XLi Rimao Hua | 2020 | Engineering2020，6，5： | 0 |
| 20 | Hydrocarbon Generation Potential Evaluation of Coal Shale Gas of Permo-Carboniferous in Jiyang Depression显示文摘In order to study the hydrocarbon-generating potential of Carboniferous-Permian coal shale in Jiyang Depression,geochemistry,petroleum geology and coal geology were applied to study the residual strata distribution of Carboniferous-Permian in Jiyang Depression,organic matter abundance,organic matter types and organic matter maturity of mudstone.The results show that the thickness of the Carboniferous-Permian residual strata in Jiyang Depression is generally 200-800 m,with a maximum thickness of 900 m;the organic matter abundance of coal-bearing shale is good,and it is type III kerogen,which is conducive to gas generation,and the maturity of organic matter reaches a mature-higher maturity stage;the hydrocarbon generation potential of Benxi Formation and Taiyuan Formation is better;Medium to good hydrocarbon source rocks is able to be found in every sag of Shanxi Formation hydrocarbon source rocks,but the scope is limited,and the overall evaluation is still medium.Generally speaking,the Permo-Carboniferous coal-bearing shale in Jiyang Depression has certain shale gas exploration potential. | Pingping Li Dawei Lv Huiyong Wang Wengui Fan Changyong Lu | 2019 | Journal of Geological Research2019，1，2： | 0 |
