| 1 | Formation condition of deep gas reservoirs in tight sandstones in Kuqa Foreland Basin显示文摘Due to the high expense of deep oil and gas exploration,prediction of gas-bearing properties before drilling is crucial for deep gas reservoir of tight sandstone.Deep tight sandstone gas fields in Kuqa Foreland Basin are characterized by high abundance,high gas saturation,high pressure,high and stable yield,which belong to high-efficiency tight gas reservoir.Based on theoretical analysis of controlling factors and mechanisms of gas-bearing properties for tight sandstone gas reservoir,and taking tight sandstone gas fields with high effectiveness such as Dibei,Keshen and Dibei gas fields in Kuqa Foreland Basin as examples,formation condition and mechanism of high-efficiency tight sandstone gas reservoir in Kuqa area are studied through a comparative analysis of typical tight sandstone gas reservoir in Sichuan Basin and Ordos Basin.The results show that the formation condition of deep gas reservoir of tight sandstone in Kuqa foreland basin includes four factors:i.e.,overpressure gas charging,fracture development,“early-oil and late-gas”accumulation process and favorable preservation condition.The overpressure gas charging and fracture development are the most important factors for formation of high-efficiency tight gas reservoirs in Kuqa Foreland Basin.High-quality source rocks,high sourcereservoir pressure difference,and overpressure filling induced thereby are preconditions for formation of tight sandstone with high gas saturation.The fracture development controls gas migration,accumulation,and high yield of tight sandstone gas reservoir.The reservoir wettability changed by the early oil charging is beneficial to late natural gas charging,and the preservation condition of high-quality gypsum cap rocks is the key factor for gas reservoirs to maintain overpressure and high gas saturation.Matching of above four favorable factors leads to the tight sandstone gas reservoir with high abundance,high gas saturation and high gas production in Kuqa Foreland Basin,which is very different from other basins.Under the condition of little difference in physical property of tight sandstone reservoir,excessive source-reservoir pressure difference,facture development,preservation condition and current formation overpressure are the most significant factors to be considered in exploration and evaluation of deep tight sandstone gas. | Xuesong Lu Mengjun Zhao Keyu Liu Qingong Zhuo Junjia Fan Zhichao Yu Yanjie Gong | 2018 | Petroleum Research2018，3，4： | 4 |
| 2 | Cell outage compensation based on Co MP and optimization of tilt显示文摘Cell outage compensation(COC) is a self-healing function of the self-organizing networks(SONs) concept for mobile wireless networks. In order to compensate the outage cell autonomously, this paper drives a solution for COC. This method is based on coordinated multiple points(Co MP) transmission and tilt adjusting. Firstly, the paper takes the coordinated pattern and tilt as the optimization objects. Then, it defines the rational objectives and the evaluation function of the situation and analysis the optimization model. Finally, based on the effective genetic algorithm(GA), the compensation mechanism is proposed. Simulation results show that this solution is better than the elder solutions in terms of coverage, interference, and throughput. | Yin Mengjun Feng Lei Li Wenjing Yu Peng Qiu Xuesong | 2015 | The Journal of China Universities of Posts and Telecommunications2015，22，5： | 3 |
| 3 | Enhanced weathering input from South Asia to the Indian Ocean since the late Eocene显示文摘nhanced silicate weathering induced by the uplift of the Himalayan-Tibetan Plateau(HTP)has been considered as the major cause of pCO_(2) decline and Cenozoic cooling.However,this hypothesis remains to be validated,largely due to the lack of a reliable reconstruction of the HTP weathering flux.Here,we present a 37-million-year record of the difference in the seawater radiogenic neodymium isotopic composition(△ε_(Nd))of Ocean Drilling Program(ODP)sites and Fe-Mn crusts between the northern and central Indian Ocean,which indicates the contribution of regional weathering input from the South Asian continent to the Indian Ocean.The results show a long-term increase in △ε_(Nd) and thus provide the first critical evidence of enhanced South Asian weathering input since the late Eocene.The evolution coincided well with major pulses of surface uplift in the HTP and global climatic transitions.Our foraminiferal eNd record suggests that tectonic uplift and silicate weathering in South Asia,especially in the Himalayas,might have played a significant role in the late Cenozoic cooling. | Zehua Song Shiming Wan Christophe Colin Christian France-Lanord Zhaojie Yu Arnaud Dapoigny Hualong Jin Mengjun Li Jin Zhang Debo Zhao Xuefa Shi Anchun Li | 2023 | Science Bulletin2023，，3： | 2 |

| 5 | Fluorobenzene diluted low-density electrolyte for high-energy density and high-performance lithium-sulfur batteries显示文摘The mass fraction of electrolytes is the crucial factor affecting the energy density of lithium-sulfur(Li-S)batteries. Due to the high porosity within the C/S cathode, high concentration of polysulfides, and side reaction in lithiun metal anode under lean electrolyte, it is extremely challenging to improve performance while reducing the electrolyte volume. Here, we report a novel electrolyte with relatively low density(1.16 g cm^(-2)), low viscosity(1.84 m Pa s), and high ionic conductivity, which significantly promotes energy density and cyclability of Li-S batteries under practical conditions. Moreover, such electrolyte enables a hybrid cathode electrolyte interphase(CEI) and solid electrolyte interface(SEI) layer with plentiful Li F, which leads to fast kinetics of ions transport and stable cyclability even under low temperatures.Compared to Li-S batteries in electrolyte employing 1,1,2,2-tetrafluoroethyl 2,2,3,3-tetrafluoropropyl ether(TTE) diluent, the ultra-thick cathode(20 mg cm^(-2)) shows a high capacity of 9.48 m Ah cm^(-2)and excellent capacity retention of 80.3% over 191 cycles at a low electrolyte-to-sulfur ratio(E/S = 2) and negative-to-positive capacity ratio(N/P = 2.5), realizing a 19.2% improvement in energy density in coin cells(from 370 to 441 Wh kg^(-1)) and a high energy density up to 467 Wh kg^(-1) in pouch cells. This study not only provides guidance for the electrolyte design but also paves the way for the development of high performance Li-S batteries under practical conditions. | Zhilong Han Shuping Li Mengjun Sun Renjie He Wei Zhong Chuang Yu Shijie Cheng Jia Xie | 2022 | Journal of Energy Chemistry2022，31，5： | 1 |

| 9 | Evolution of Asian drying since 30 Ma revealed by clay minerals record in the West Pacific and its tectonic-climatic forcing显示文摘As the second largest dust source on the globe,the tectonic and climatic evolution of continental Asia has an important impact on regional and global climate change.The West Pacific is the main sediment sink for eolian dust transported eastward from the Asian interior.Clay minerals,as the major fine-grained weathering products of continental rocks,can be readily transported by wind or currents over long distances and thus have been widely used in the reconstruction of paleoclimate and weathering history.However,the overall evolutionary tendency and response mechanism of clay mineral records over large spatial and long timescales across Asia remain unclear.Here,two continuous and high-resolution clay mineral records since 30 Ma were reconstructed from sediments at Deep Sea Drilling Program(DSDP)Sites 292 and 296 in the Philippine Sea.Clay minerals and Sr-Nd isotope compositions were used to constrain provenance and reconstruct the drying history of the dust source region since the Oligocene.The results show that the clay-sized detrital sediments in the Philippine Sea are a mixture of Asian eolian dust and volcanic materials from the West Pacific arcs.Based on the clay mineral compositions and eolian flux,we reveal that the Asian interior has been continuously drying since the late Oligocene and that stepwise enhanced aridification occurred at approximately 20,14,7,and 3 Ma.Compared with other regions of the world,the relative contents of illite and chlorite increased more dramatically in Asia during the late Cenozoic,and the inconsistency became more obvious at approximately 20 Ma.Since 3 Ma,illite and chlorite have increased consistently across the globe.Combined with the Asian tectonic and climatic history,we suggest that the increase in illite and chlorite from Asia between 20 and 3 Ma was mainly in response to the uplift of the Himalayan-Tibetan Plateau,whereas after 3 Ma,it was primarily controlled by global cooling driven by the expansion of the Arctic ice sheet. | Yi TANG Shiming WAN Debo ZHAO Zhaojie YU Zhaokai XU Jin ZHANG Zehua SONG Mengjun LI Hualong JIN Wenjun JIAO Hongkun DONG Anchun LI | 2023 | Science China Earth Sciences2023，66，6： | 0 |
| 10 | Shikimic acid accelerates phase change and flowering in Chinese jujube显示文摘The juvenile-to-adult phase change with first flowering as the indicator plays a crucial role in the lifecycle of fruit trees. However, the molecular mechanisms underlying phase change in fruit trees remain largely unknown. Shikimic acid (ShA) pathway is a main metabolic pathway closely related to the synthesis of hormones and many important secondary metabolites participating in plant phase change. So,whether ShA regulates phase change in plants is worth clarifying. Here, the distinct morphological characteristics and the underlying mechanisms of phase change in jujube (Ziziphus jujuba Mill.), an important fruit tree native to China with nutritious fruit and outstanding tolerance abiotic stresses, were clarified. A combined transcriptome and metabolome analysis found that ShA is positively involved in jujube(Yuhong’×Xing 16’) phase change. The genes in the upstream of ShA synthesis pathway (ZjDAHPS, ZjDHQS and ZjSDH), the contents of ShA and the downstream secondary metabolites like phenols were significantly upregulated in the phase change period. Further, the treatment of spraying exogenous ShA verified that ShA at a very low concentration (60 mg·L^(-1)) can substantially speed up the phase change and flowering of jujube and other tested plants including Arabidopsis, tomato and wheat. The exogenous ShA (60 mg·L^(-1)) treatment in jujube seedlings could increase the accumulation of endogenous ShA, enhance leaf photosynthesis and the synthesis of phenols especially flavonoids and phenolic acids, and promote the expression of genes (ZjCOs, ZjNFYs and ZjPHYs) involved in flowering pathway. Basing on above results, we put forward a propose for the underlying mechanism of ShA regulating phase change, and a hypothesis that ShA could be considered a phytohormone-like substance because it is endogenous, ubiquitous, movable and highly efficient at very low concentrations. This study highlights the critical role of ShA in plant phase change and its phytohormone-like properties. | Xianwei Meng Zhiguo Liu Li Dai Weiqiang Zhao Jiurui Wang Lili Wang Yuanpei Cui Ying Li Yinshan Cui Yao Zhang Luyao Wang Fengjiao Yu Jin Zhao Mengjun Liu | 2024 | Horticultural Plant Journal2024，10，2： | 0 |
| 11 | Study on Effects of Ascorbyl Propyl Hyaluronate显示文摘The moisturizing,barrier protection,firming effects of Ascorbyl Propyl Hyaluronate(V_(C)-HA)are studied.The moisturizing effect was evaluated by detecting hygroscopicity and water-retention capacity.A model of 3D skin injury was established to evaluate the barrier protection effect by detecting the changes in the histomorphological structure of the model and the barrier related proteins.Expression level of type Ⅰ collagen in FB was detected to evaluate the firming effect(Filaggrin,FLG).The results show that V_(C)-HA has better moisturizing effect and obvious barrier protection effects at the concentration of 300μg/mL.Expression level of type I collagen increases with the increase of the V_(C)-HA concentration in the range of 100~6,250μg/mL.In conclusion,a certain concentration of V_(C)-HA has better moisturizing,barrier protection and firming effects. | Yu Tiantian Guo Kai Lin Mengjun Cui Benwen Wang Huihui Ji Shengli | 2022 | China Detergent & Cosmetics2022，7，3： | 0 |
| 12 | Self-Healing Based on Cooperative Transmission via Bender's Decomposition in Cloud Radio Access Network显示文摘To employ the network resources more effectively and fl exibly,cloud radio access network(C-RAN) adopts centralized network construction and management. Since the new network characteristics,the self-healing is reliable distinguish compared with previous studies. This paper drives a solution for selfhealing based on cooperative transmission and power adjustment under C-RAN self-healing management architecture. This compensation model with the aim to maximize the number of connected UEs and optimize power regulation is solved by Benders' decomposition algorithm. And through the simulation,this paper verifies the speediness and effectiveness of this scheme. | YIN Mengjun LI Wenjing YU Peng FENG Lei QIU Xuesong | 2015 | China Communications2015，12，11： | 0 |
| 13 | Establishment of an in vitro reporter system for screening HBx-targeting molecules显示文摘Chronic hepatitis B virus (HBV) infection remains a global public health problem. HBV-encoded X protein (HBx) is a multifunctional regulator that is required to initiate and maintain productive HBV infection, and is involved in HBV-related hepatocellular carci noma (HCC). Inhibitors that in terfere with the functions of HBx could be useful not only for the inhibition of HBV replication but also for the prevention or treatment of HBV-related HCC. To screen molecules that target HBx on a large scale remains a tech nical challenge due to a lack of sensitive and high-throughput system .In this work, we established an in vitro bioluminescent reporter system for screening HBx-targeting molecules. The system is based on a secretory fusion protein that combines HBx and NanoLuc (HBx-Nluc). The measured activity of NanoLuc in the culture supernatant of HBx-Nluc-expressing cells directly reflects the level of secreted HBx-Nluc. HBx protein-targeting intracellular anti-HBx single-chain variable fragment and RNA-targeting shRNA significantly reduced the secreted NanoLuc activity in HBx-Nluc-expressing cells. This system is simple and sensitive, and compatible with continuous non-disruptive screening, suggesting its potential usefulness for highthroughput screening and evaluating HBx-targeting molecules. | Chenjian Gu Shuai Tao Kongying Hu Lijun Ming Mengjun Luo Huimin Guo Yu Su Jing Liu Youhua Xie | 2019 | Acta Biochimica et Biophysica Sinica2019，51，4： | 0 |
| 14 | Tuning Solid Interfaces via Varying Electrolyte Distributions Enables High-Performance Solid-State Batteries显示文摘Solid/solid interface is the major challenge for high-performance solid-state batteries.Solid electrolytes(SEs)play a crucial role in the fabrication of effective interfaces in solid-state batteries.Herein,the electrolyte distribution with varied particle sizes is tuned to construct solid-state batteries with excellent performance at different operating temperatures.Solid-state batteries with the configuration S/L(small-sized SE in composite cathode and large-sized SE in electrolyte layer)show the best performance at room temperature(168 mA h g^(−1) at 0.2 C,retention of 99%,100 cycles)and−20°C(89 mA h g^(−1) at 0.05 C),while the configuration S/S displays better performance at elevated temperature.The superior performance of S/L battery is associated with faster lithium-ion dynamics due to the better solid/solid interface between active materials and electrolytes.Moreover,the inferior performance at 60℃is caused by the formation of voids and cracks in the electrolyte layer during cycling.In contrast,the S/S battery delivers superior performance at elevated operating temperature because of the integrated structure.This work confirms that tailoring electrolyte size has significant effect on fabricating all-climate solid-state batteries. | Linfeng Peng Chuang Yu Ziqi Zhang Ruonan Xu Mengjun Sun Long Zhang Shijie Cheng Jia Xie | 2023 | Energy & Environmental Materials2023，6，2： | 0 |
| 15 | Chromosome-scale assembly reveals asymmetric paleo-subgenome evolution and targets for the acceleration of fungal resistance breeding in the nut crop, pecan显示文摘Pecan(Carya illinoinensis)is a tree nut crop of worldwide economic importance that is rich in healthpromoting factors.However,pecan production and nut quality are greatly challenged by environmental stresses such as the outbreak of severe fungal diseases.Here,we report a high-quality,chromosome-scale genome assembly of the controlled-cross pecan cultivar‘Pawnee’constructed by integrating Nanopore sequencing and Hi-C technologies.Phylogenetic and evolutionary analyses reveal two whole-genome duplication(WGD)events and two paleo-subgenomes in pecan and walnut.Time estimates suggest that the recent WGD event and considerable genome rearrangements in pecan and walnut account for expansions in genome size and chromosome number after the divergence from bayberry.The two paleo-subgenomes differ in size and protein-coding gene sets.They exhibit uneven ancient gene loss,asymmetrical distribution of transposable elements(especially LTR/Copia and LTR/Gypsy),and expansions in transcription factor families(such as the extreme pecan-specific expansion in the far-red impaired response 1 family),which are likely to reflect the long evolutionary history of species in the Juglandaceae.A whole-genome scan of resequencing data from 86 pecan scab-associated core accessions identified 47 chromosome regions containing 185 putative candidate genes.Significant changes were detected in the expression of candidate genes associated with the chitin response pathway under chitin treatment in the scab-resistant and scabsusceptible cultivars‘Excell’and‘Pawnee’.These findings enable us to identify key genes that may be important susceptibility factors for fungal diseases in pecan.The high-quality sequences are valuable resources for pecan breeders and will provide a foundation for the production and quality improvement of tree nut crops. | Lihong Xiao Mengjun Yu Ying Zhang Jie Hu Rui Zhang Jianhua Wang Haobing Guo He Zhang Xinyu Guo Tianquan Deng Saibin Lv Xuan Li Jianqin Huang Guangyi Fan | 2021 | Plant Communications2021，2，6： | 0 |
| 16 | Fast Solution Method for the Large-scale Unit Commitment Problem with Long-term Storage显示文摘Long-term storage(LTS)can provide various services to address seasonal fluctuations in variable renewable energy by reducing energy curtailment.However,long-term unit commitment(UC)with LTS involves mixed-integer programming with large-scale coupling constraints between consecutive intervals(state-of-charge(SOC)constraint of LTS,ramping rate,and minimum up/down time constraints of thermal units),resulting in a significant computational burden.Herein,an iterative-based fast solution method is proposed to solve the long-term UC with LTS.First,the UC with coupling constraints is split into several sub problems that can be solved in parallel.Second,the solutions of the sub problems are adjusted to obtain a feasible solution that satisfies the coupling constraints.Third,a decoupling method for long-term time-series coupling constraints is proposed to determine the global optimization of the SOC of the LTS.The price-arbitrage model of the LTS determines the SOC boundary of the LTS for each sub problem.Finally,the sub problem with the SOC boundary of the LTS is iteratively solved independently.The proposed method was verified using a modified IEEE 24-bus system.The results showed that the computation time of the unit combination problem can be reduced by 97.8%,with a relative error of 3.62%. | Bo Li Chunjie Qin Ruotao Yu Wei Dai Mengjun Shen Ziming Ma Jianxiao Wang | 2023 | Chinese Journal of Electrical Engineering2023，9，3： | 0 |
| 17 | The spatial transcriptomic landscape of human gingiva in health and periodontitis显示文摘The gingiva is a key oral barrier that protects oral tissues from various stimuli.A loss of gingival tissue homeostasis causes periodontitis,one of the most prevalent inflammatory diseases in humans.The human gingiva exists as a complex cell network comprising specialized structures.To understand the tissue-specific pathophysiology of the gingiva,we applied a recently developed spatial enhanced resolution omics-sequencing(Stereo-seq)technique to obtain a spatial transcriptome(ST)atlas of the gingiva in healthy individuals and periodontitis patients.By utilizing Stereo-seq,we identified the major cell types present in the gingiva,which included epithelial cells,fibroblasts,endothelial cells,and immune cells,as well as subgroups of epithelial cells and immune cells.We further observed that inflammation-related signalling pathways,such as the JAK-STAT and NF-κB signalling pathways,were significantly upregulated in the endothelial cells of the gingiva of periodontitis patients compared with those of healthy individuals.Additionally,we characterized the spatial distribution of periodontitis risk genes in the gingiva and found that the expression of IFI16 was significantly increased in endothelial cells of inflamed gingiva.In conclusion,our Stereo-seq findings may facilitate the development of innovative therapeutic strategies for periodontitis by mapping periodontitis-relevant genes and pathways and effector cells. | Zongshan Shen Ran Zhang Yunjia Huang Jiayao Chen Mengjun Yu Chunhua Li Yong Zhang Lingling Chen Xin Huang Jichen Yang Zhengmei Lin Songlin Wang Bin Cheng | 2024 | Science China(Life Sciences)2024，67，4： | 0 |
