| 1 | Climatic and lake environmental changes in the Serling Co region of Tibet over a variety of timescales显示文摘The Serling Co region is located at the transitional zone of the interaction between the Indian monsoon and the westerlies over the Tibetan Plateau. The Serling Co lake covers a water area of2,389 km2(June 2017) in a 45,530 km2drainage basin. Under the dramatic hydro-meteorological changes on the Tibetan Plateau in recent decades, and complex hydrological compositions of rivers and lakes in the basin, the lake area expanded by 43%, from1,667 km2in 1976, to 2,389 km2in 2017 (1)In 2014 it surpassed Nam Co as the largest lake on the Tibetan Plateau [2], and exerts significant effect on regional environmental conditions. | Liping Zhu Junbo Wang Jianting Ju Ning Ma Yinsheng Zhang Chong Liu Boping Han Linshan Liu Mingda Wang Qingfeng Ma | 2019 | Science Bulletin2019，64，7： | 13 |
| 2 | Classification of Tibetan lakes based on variations in seasonal lake water temperature显示文摘Widespread lakes on the Tibetan Plateau(TP)are valuable archives for investigating climate and environment changes, which could provide essential information on the mechanisms of past climate changes on the TP and their interaction with the global climate systems.However, there is a lack of in-depth investigation of modern limnological processes in the Tibetan lakes, which hampers the understanding of paleolimnological records and lake ecosystem succession. In this study, we performed continuous temperature monitoring at two lakes, Bangong Co, a freshwater lake in the western TP, and Dagze Co, a brackish lake in the central TP, in order to characterize the patterns of seasonal temperature variability, stratification,and mixing. Temperature data for an entire hydrological year demonstrate that Bangong Co is a dimictic lake and that Dagze Co is a meromictic lake. The higher salinity in the deep water at Dagze Co prevents the lake from overturning completely, and this finding is supported by simulations using a physical limnological model Lake Analyzer. Continuous lake water temperature monitoring provides fundamental data for classifying Tibetan lakes, as well as the hydrological basis for understanding their paleolimnological records and ecosystem succession. | Mingda Wang Juzhi Hou Yanbin Lei | 2014 | Chinese Science Bulletin2014，59，34： | 10 |
| 3 | Distribution of GDGTs in lake surface sediments on the Tibetan Plateau and its influencing factors显示文摘Quantitative paleotemperature records are vital not only for verifying and improving the accuracy of climate model simulations, but also for estimating the amplitude of temperature variability under global warming scenarios. The Tibetan Plateau(TP) affects atmospheric circulation patterns due to its unique geographical location and high elevation, and studies of the mechanisms of climate change on the TP are potentially extremely valuable for understanding the relationship of the region with the global climate system. With the development of biomarker-based proxies, it is possible to use lake sediments to quantitatively reconstruct past temperature variability. The source of Glycerol Dialkyl Glycerol Tetraethers(GDGTs) in lake sediments is complex, and their distribution is controlled by both climatic and environmental factors. In this work, we sampled the surface sediments of 27 lakes on the TP and in addition obtained surface soil samples from six of the lake catchments. We analyzed the factors that influence GDGT distribution in the lake sediments, and established quantitative relationship between GDGTs and Mean Annual Air Temperature(MAAT). Our principal findings are as follows: the majority of GDGTs in the lake sediments are b GDGTs, followed by crenarchaeol and GDGT-0. In most of the lakes there were no significant differences between the GDGT distribution within the lake sediments and the soils in the same catchment, which indicates that the contribution of terrestrial material is important. i GDGTs in lake sediments are mainly influenced by water chemistry parameters(p H and salinity), and that in small lakes on the TP, TEX_(86) may act as a potential proxy for lake p H; however, in contrast b GDGTs in the lake sediments are mainly controlled by climatic factors. Based on the GDGT distribution in the lake sediments, we used proxies(MBT, CBT) and the fractional abundance of b GDGTs(f_(abun)) to establish calibrations between GDGTs and MAAT, respectively, which potentially provide the basis for paleoclimatic reconstruction on the TP. | WANG MingDa LIANG Jie HOU JuZhi HU Liang | 2016 | Science China Earth Sciences2016，59，5： | 8 |
| 4 | Lithium metal batteries for high energy density:Fundamental electrochemistry and challenges显示文摘The dependence on portable devices and electrical vehicles has triggered the awareness on the energy storage systems with ever-growing energy density.Lithium metal batteries(LMBs)has revived and attracted considerable attention due to its high volumetric(2046 m Ah cm-3),gravimetric specific capacity(3862 m Ah g^(-1))and the lowest reduction potential(-3.04 V vs.SHE.).However,during the electrochemical process of lithium anode,the growth of lithium dendrite constitutes the biggest stumbling block on the road to LMBs application.The undesirable dendrite not only limit the Coulombic efficiency(CE)of LMBs,but also cause thermal runaway and other safety issues due to short-circuits.Understanding the mechanisms of lithium nucleation and dendrite growth provides insights to solve these problems.Herein,we summarize the electrochemical models that inherently describe the lithium nucleation and dendrite growth,such as the thermodynamic,electrodeposition kinetics,internal stress,and interface transmission models.Essential parameters of temperature,current density,internal stress and interfacial Li+flux are focused.To improve the LMBs performance,state-of-the-art optimization procedures have been developed and systematically illustrated with the intrinsic regulation principles for better lithium anode stability,including electrolyte optimization,artificial interface layers,threedimensional hosts,external field,etc.Towards practical applications of LMBs,the current development of pouch cell LMBs have been further introduced with different assembly systems and fading mechanism.However,challenges and obstacles still exist for the development of LMBs,such as in-depth understanding and in-situ observation of dendrite growth,the surface protection under extreme condition and the self-healing of solid electrolyte interface. | Mingda Gao Hui Li Li Xu Qing Xue Xinran Wang Ying Bai Chuan Wu | 2021 | Journal of Energy Chemistry2021，30，8： | 6 |
| 5 | MicroRNA-132 in the Adult Dentate Gyrus is Involved in Opioid Addiction Via Modifying the Differentiation of Neural Stem Cells显示文摘MicroRNA-132(miR-132), a small RNA that regulates gene expression, is known to promote neurogenesis in the embryonic nervous system and adult brain.Although exposure to psychoactive substances can increase miR-132 expression in cultured neural stem cells(NSCs)and the adult brain of rodents, little is known about its role in opioid addiction. So, we set out to determine the effect of miR-132 on differentiation of the NSCs and whether this effect is involved in opioid addiction using the rat morphine self-administration(MSA) model. We found that miR-132 overexpression enhanced the differentiation of NSCs in vivo and in vitro. Similarly, speci?c overexpression of miR-132 in NSCs of the adult hippocampal dentate gyrus(DG) during the acquisition stage of MSA potentiated morphine-seeking behavior. These ?ndings indicate that miR-132 is involved in opioid addiction,probably by promoting the differentiation of NSCs in the adult DG. | Meng Jia Xuewei Wang Haolin Zhang Can Ye Hui Ma Mingda Yang Yijing Li Cailian Cui | 2019 | Neuroscience Bulletin2019，35，3： | 6 |

| 8 | Efficient production of chemicals from microorganism by metabolic engineering and synthetic biology显示文摘The use of traditional chemical catalysis to produce chemicals has a series of drawbacks,such as high dependence on fossil resources,high energy consumption,and environmental pollution.With the development of synthetic biology and metabolic engineering,the use of renewable biomass raw materials for chemicals synthesis by constructing efficient microbial cell factories is a green way to replace traditional chemical catalysis and traditional microbial fermentation.This review mainly summarizes several types of bulk chemicals and high value-added chemicals using metabolic engineering and synthetic biology strategies to achieve efficient microbial production.In addition,this review also summarizes several strategies for effectively regulating microbial cell metabolism.These strategies can achieve the coupling balance of material and energy by regulating intracellular material metabolism or energy metabolism,and promote the efficient production of target chemicals by microorganisms. | Yang Zhang Jing Yu Yilu Wu Mingda Li Yuxuan Zhao Haowen Zhu Changjing Chen Meng Wang Biqiang Chen Tianwei Tan | 2021 | Chinese Journal of Chemical Engineering2021，34，2： | 2 |

| 10 | Topological Comparison and Analysis of Medium-voltage and High-power Direct-linked PV Inverter显示文摘Among all the renewable energy sources,the installed capacity of solar power generation is the fastest growing in recent years,so photovoltaic(PV)power generation still has great market potential.Compared with low-power systems,large-scale PV systems are more commercially attractive,because they can reduce the cost of the system per watt.The PV inverters with centralized and string structure have been applied in large-scale PV plant,but it is difficult to further increase the voltage and power levels for a single converter.In addition,the line-frequency isolation transformer requires a large amount of materials and has a large volume and weight.Therefore,it is a current trend for large-scale PV system to increase the voltage and power levels to directly connect to the medium-voltage power grid.Based on this,this paper investigates and compares several topologies of PV inverters without line-frequency transformer,including the MMC structure and the three-phase cascaded H-bridge(CHB)structure,which are able to directly connect to the 35kV medium-voltage power grid,and can not only make the voltage and power levels higher,but also further reduce the cost and volume of the whole system. | Xing Zhang Mingda Wang Tao Zhao Wang Mao Yuhua Hu Renxian Cao | 2019 | CES Transactions on Electrical Machines and Systems2019，3，4： | 2 |

| 13 | Catalytic effect and reaction mechanism of Ti doped in NaAlH_4: A review显示文摘Catalytic effect and hydrogen reaction mechanism of Ti doped in NaAlH4 were elaborated in this paper, and current viewpoints about Ti active species in hydrogen reaction were discussed. In a further step, the possibility and practicality of the hydrogen reaction mechanism of Ti-doped NaAlH_4 were elucidated. They could be summarized as follows: while the current theory about the hydrogen reaction mecha-nism of Ti-doped NaAlH_4 should be further improved and modified, the research on Ti-doped NaAlH_4 would be a recommendable pattern for the catalyst research in other metal complex hydrides. | WANG Qiang CHEN YunGui WU ChaoLing TAO MingDa | 2008 | Chinese Science Bulletin2008，53，12： | 1 |

| 15 | Experimental Investigation of Local Scour Around Artificial Reefs in Steady Currents显示文摘Artificial reef is a man-made object that is deployed purposefully on the seafloor to restore the offshore fishery resources and the ecological environment.To secure its ecological effects,it is important to study the possible instability of artificial reefs,like drifting and reversing caused by burial and scour in different seafloor conditions.In the present study,experiments of local scour around an artificial reef are carried out in steady currents.The effect of the open-area ratios and the open-hole heights of the cubic reefs,and the bottom angles of the triangular reefs on the time-scale of the scour process and the equilibrium scour depth are investigated.The results indicate that for the cubic artificial reef,the scour depth decreases with the increasing open-area ratios,and increases with the increasing open-hole heights.In the present study,the optimal prototype of the cubic reef with an open-area ratio of 0.49 and open-height of 0.7 m produces the minimum scour depth.For the triangular reef,the scour depth increases when the bottom angle increases.Moreover,based on the experimental results,empirical equations of the effects of the cut-opening and the bottom angle on the maximum equilibrium scour depth are proposed.The formulas will provide theoretical support and practical guidance for the optimized design and construction of artificial reefs. | TANG Yanli WEI Shuangwu YANG Mingda WANG Xinxin ZHAO Fenfang | 2022 | Journal of Ocean University of China2022，21，2： | 0 |
| 16 | Adjusting Nitrogen Application in Accordance with Soil Water Availability Enhances Yield and Water Use by Regulating Physiological Traits of Maize under Drip Fertigation显示文摘Knowledge of the interactive effects of water and nitrogen(N)on physio-chemical traits of maize(Zea mays L.)helps to optimize water and N management and improve productivity.A split-plot experiment was conducted with three soil water conditions(severe drought,moderate drought,and fully water supply referring to 45%-55%,65%-75%,and 85%-95%field capacity,respectively)and four N application rates(N0,N150,N240,and N330 referring to 0,150,240,330 kg N ha^(-1)respectively)under drip fertigation in 2014 and 2015 in the Huang-Huai-Hai Plain of China.The results indicated that drought stress inhibited physiological activity of plants(leaf relative water content,root bleeding sap,and net photosynthetic rate),resulting in low dry matter accumulation after silking,yield,and N uptake,whereas increased WUE and NUE.N application rates over than 150 kg ha^(-1)aggravated the inhibition of physiological activity under severe drought condition,while it was offset under moderate drought condition.High N application rates(N330)still revealed negative effects under moderate drought condition,as it did not consistently enhance plant physiological activity and significantly reduced N uptake as compared to the N240 treatment.With fully water supply,increasing N application rates synergistically enhanced physiological activity,promoted dry matter accumulation after silking,and increased yield,WUE,and N uptake.Although the N240 treatment reduced yield by 5.4%in average,it saved 27.3%N under full water supply condition as compared with N330 treatment.The results indicated that N regulated growth of maize in aspects of physiological traits,dry matter accumulation,and yield as well as water and N use was depended on soil water status.The appropriate N application rates for maize production was 150 kg ha^(-1)under moderate drought or 240 kg ha^(-1)under fully water supply under drip fertigation,and high N supply(>150 kg ha^(-1))should be avoided under severe drought condition. | Mingda Yang Shouchen Ma Fujian Mei Li Wei Tongchao Wang Xiaokang Guan | 2021 | Phyton-International Journal of Experimental Botany2021，90，2： | 0 |

| 18 | Plant Membrane Transport Research in the Post-genomic Era显示文摘Membrane transport processes are indispensable for many aspects of plant physiology including mineral nutrition,solute storage,cell metabolism,cell signaling,osmoregulation,cell growth,and stress responses.Completion of genome sequencing in diverse plant species and the development of multiple genomic tools have marked a new era in understanding plant membrane transport at the mechanistic level.Genes coding for a galaxy of pumps,channels,and carriers that facilitate various membrane transport processes have been identified while multiple approaches are developed to dissect the physiological roles as well as to define the transport capacities of these transport systems.Furthermore,signaling networks dictating the membrane transport processes are established to fully understand the regulatory mechanisms.Here,we review recent research progress in the discovery and characterization of the components in plant membrane transport that take advantage of plant genomic resources and other experimental tools.We also provide our perspectives for future studies in the field. | Ren-Jie Tang Mingda Luan Chao Wang Dhondup Lhamo Yang Yang Fu-Geng Zhao Wen-Zhi Lan Ai-Gen Fu Sheng Luan | 2020 | Plant Communications2020，1，1： | 0 |
| 19 | Paleohydrological Changes in the Western Tibetan Plateau over the Past 16,000 years Based on Sedimentary Records of n-Alkanes and Grain Size显示文摘Both monsoons and westerlies have exerted influence on climate dynamics over the Tibetan Plateau(TP) since the last deglaciation, producing complex patterns of paleohydroclimatic conditions. Diverse proxy records are essential to forge a robust understanding of the climate system on the TP. Currently, there is a general lack of understanding of the response of inland lakes over the TP to climate change, especially glacier-fed lakes. Paleohydrological reconstructions of such lakes could deepen our understanding of the history of lake systems and their relationship to regional climate variability. Here we use records of n-alkanes and grain size from the sediments of Bangong Co in the western TP to reconstruct paleohydrological changes over the past 16,000 years. The Paq record(the ratio of non-emergent aquatic macrophytes versus emergent aquatic macrophytes and terrestrial plants) is generally consistent with the variations in summer temperature and precipitation isotopes. The changes in grain-size distributions show a similar trend to Paq but with less pronounced fluctuations in the early-middle Holocene. The new data combined with previous results from the site demonstrate that: 1) Bangong Co experienced relatively large water-level fluctuations during the last deglaciation, with a steadily high lake-level during the early-middle Holocene and a decreasing lake-level in the late Holocene;2) The lake level fluctuations were driven by both high summer temperatures via the melting water and monsoon precipitation. However, the dominant factor controlling lake level changed over time. The lake-level history at Bangong Co deduced from the n-alkanes and grain-size records reveals the past hydrological changes in the catchment area, and stimulates more discussion about the future of glacier-fed lakes under the conditions of unprecedented warming in the region. | WANG Mingda YANG Yaping ZHANG Jiawu HOU Juzhi | 2020 | Acta Geologica Sinica(English Edition)2020，94，3： | 0 |
| 20 | Lacustrine Record of 1954 Flood Event on Begnas and Rupa Lake, Central Nepal显示文摘In recent decades, there have been discussions and predictions regarding the impact of climate on floods, due to its socioeconomic and environmental consequences. For accurate prediction of future flood events and their impacts, it is crucial to have an improved understanding on past flood events. Lacustrine sediments have been used as a natural archive to study the past flood events. Here, we study the impact of 1954 flood event on the lacustrine environment of Bengas and Rupa Lake in central Nepal based on X-ray fluorescence spectrometry(XRF) element analysis, magnetic susceptibility(MS), total organic carbon(TOC) and the biomarker molecular compositions. Results showed that 1954 flood event had significant impacts on the two lakes in terms of detrital input, organic matter deposition and aquatic production. Before the flood event, both two studied lakes had relatively lower catchment erosion rate, lower organic matter deposition and aquatic production. During the flood event, catchment erosion and aquatic production increased in both lakes due to mass transport deposits and the increased nutrition loading attributed to flood event. Following the flood event, Begnas Lake showed the sharp increase in organic matter deposition, whereas in the Rupa Lake organic matter deposition showed minor changes. The difference in organic matter deposition in lakes during flooding event is likely due to detrital material brought and deposited by the flood activity. Overall our results suggest that lacustrine sediments are sensitive to the extreme event and would be an ideal archive for the reconstruction of flood events. | Sudip ACHARYA LI Can-Ge JI Kejia SUN Zhe WANG Mingda HOU Juzhi | 2020 | Acta Geologica Sinica(English Edition)2020，94，3： | 0 |
