| 2 | Reliability Simulation and Design Optimization for Mechanical Maintenance显示文摘Reliability model of a mechanical product system will be newly reconstructed and maintenance cost will increase because failed parts can be replaced with new components during service,which should be accounted for in system design. In this paper,a reliability model and reliability-based design optimization methodology for maintenance are presented. First,based on the time-to-failure density function of the part of the system,the age distributions of all parts of the system during service are investigated,a reliability model of the mechanical system for maintenance is developed. Then,reliability simulations of the systems with Weibull probability density functions are performed,the system minimum reliability and steady reliability for maintenance are defined based on reliability simulation during the life cycle of the system. Thirdly,a maintenance cost model is developed based on replacement rates of the parts,a reliability-based design optimization model for maintenance is presented,in which total life cycle cost is considered as design objective and system reliability as design constrain. Finally,the reliability-based design optimization methodology for maintenance is used to design of a link ring for the chain conveyor,which shows that optimal design with the lowest maintenance cost can be obtained,and minimum reliability and steady reliability of the system can satisfy requirement of system reliability during service of the chain conveyor. | LIU Deshun HUANG Liangpei YUE Wenhui XU Xiaoyan | 2009 | Chinese Journal of Mechanical Engineering2009，22，4： | 4 |

| 4 | Understanding divergent domestication traits from the whole-genome sequencing of swamp-and river-buffalo populations显示文摘Domesticated buffaloes have been integral to rice-paddy agro-ecosystems formillennia,yet relatively little is known about the buffalo genomics.Here,we sequenced and assembled reference genomes for both swamp and river buffaloes and we re-sequenced 230 individuals(132 swamp buffaloes and 98 river buffaloes)sampled from across Asia and Europe.Beyond the many actionable insights that our study revealed about the domestication,basic physiology and breeding of buffalo,we made the striking discovery that the divergent domestication traits between swamp and river buffaloes can be explained with recent selections of genes on social behavior,digestion metabolism,strengths and milk production. | Xier Luo Yu Zhou Bing Zhang Yi Zhang Xiaobo Wang Tong Feng Zhipeng Li Kuiqing Cui Zhiqiang Wang Chan Luo Hui Li Yanfei Deng Fenghua Lu Jianlin Han Yongwang Miao Huaming Mao Xiaoyan Yi Cheng Ai Shigang Wu Alun Li Zhichao Wu Zijun Zhuo Do Da Giang Bikash Mitra Mohammad Farhad Vahidi Shahid Mansoor Sahar Ahmed Al-Bayatti Eka Meutia Sari Neena Amatya Gorkhali Sigit Prastowo Laiba Shafique Guoyou Ye Qian Qian Baoshan Chen Deshun Shi Jue Ruan Qingyou Liu | 2020 | National Science Review2020，7，3： | 3 |

| 6 | Expression Pattern and Target Gene of bbu-miR-103-1 in Buffalo(Bubalus bubalis) at Lactation and Non-lactation Periods显示文摘[Objective] The paper aimed to investigate the expression pattern of bbu-miR-103-1 in buffalo( Bubalus bubalis) at lactation and non-lactation periods,and to predict its target gene and function. [Method]Expression pattern of bbu-miR-103-1 at lactation and non-lactation periods were detected by qRT-PCR.The precursor expression plasmid of bbu-miR-103-1 was constructed and named LpEZX-pre-miR-103-1. It was packaged and propagated to produce high-titer lentivirus in 293 T cell lines,which could be used to infect buffalo mammary epithelial cells( BMECs) and over express bbu-miR-103-1. The inhibitor of bbu-miR-103-1 was chemically synthesized and transfected into BMECs to suppress bbu-miR-103-1 at the same time. The relative expression of pantothenate kinase 3( PANK3) and milk fat metabolism related genes were detected by qRT-PCR. [Result]The relative expression of bbu-miR-103-1 at lactation period was 5. 29 times higher than that at non-lactation period in buffalo( P < 0. 01). The LpEZX-pre-miR-103-1 had been successfully constructed and packaged with the infection titer of 3. 47 × 10~6 PFU/m L. Overexpress or suppress of bbu-miR-103-1 extremely down-regulated or up-regulated the expression level of PANK3 in BMECs( P < 0. 01).Over expression of bbu-miR-103-1 extremely enhanced the expression of Acetyl-CoA carboxylase alpha( ACACA),Glycerol-3-phosphate acyltransferase 1 mitochondrial( GPAM),Diacylglycerol Oacyltransferase 1( DGAT1) and Pyruvate dehydrogenase lipoamide kinase isozyme 4( PDK4)( P < 0. 01),and also significantly up-regulated the expression of sterol regulatory element binding protein-1c( SREBP1c),Adipose differentiation-related protein( ADFP),Cluster of differentiation36( CD36),Acetyl-Co A synthetase short-chain subfamily member 1( ACSS1)( P < 0. 05). Over expression of bbu-miR-103-1 down-regulated the expression of PANK3,and improved the mRNA level of SREBP1c by feedback regulation,finally promoting the de novo synthesis of fatty acid beginning with ACACA.[Conclusion] bbu-miR-103-1 plays an important role in enhancing milk fatty acid synthesis,which provides a molecular base for revealing formation and regulatory mechanism of high-level milk fat in buffalo. | Cai Xiaoyan Li Sheng Chen Qiuping Wang Ping Deng Kai Liu Qingyou Shi Deshun | 2017 | Animal Husbandry and Feed Science2017，9，3： | 1 |

| 9 | Formation mechanism of carbonates in the lacustrine muddy shale and it implication for shale oil and gas: A case study of source rocks in Member 4 and Member 3 of Shahejie Formation, Dongying sag显示文摘Through analysis of microscopic characteristics,mineral components,elements and isotopes,the genetic mechanism of carbonates in the deep lacustrine source rocks in the upper submember of Member 4 and lower submember of Member 3 of Shahejie Formation in Dongying sag,is well investigated.The results show that four types of carbonates in the deep lake,i.e.,lenticular coarse crystalline carbonate,lamellar micro-fine crystalline carbonate,lamellar cryptocrystalline carbonate and massive cryptocrystalline carbonate.Of which,the lenticular coarse crystalline carbonate is formed by diagenetic recrystallization.For the lamellar micro-fine crystalline carbonate and the lamellar cryptocrystalline carbonate,through the alga photosynthesis,the carbon dioxide(CO_(2))is constantly extracted from water,thus the concentration of CO_(3)^(-2) ion in water increases,and then the CO_(3)^(-2) ion reacts with Ca2+ ion in lake water surface to form the carbonates;the saline water environment is favorable for preservation of carbonate particles which mostly occur in lamellar micro-fine crystalline;in the brackish water environment,the water is deep,and the carbonate crystalline beneath the carbonate compensation depth surface is usually is dissolved,and most of lamellar cryptocrystalline are preserved.The massive cryptocrystalline carbonate is formed by the sedimentary carbonate which transport from shallow water to deep water by gravity flow.To some extent,the carbonates control reservoir property and compressibility of muddy shale in the upper submember of Member 4 and lower submember of Member 3 of Shahejie Formation in Dongying sag,and provide important information for reconstruction of sedimentary environment of the ancient lake. | Yong Wang Huiming Liu Guoqi Song Xuefeng Hao Deshun Zhu Deyan Zhu | 2018 | Petroleum Research2018，3，3： | 1 |

| 11 | Study on quality evaluation model in multi-station assembly processes显示文摘Based on features of dimension variation propagation in multi-station assembly processes,a new quality evaluation model of assembly processes is established. Firstly,the error source of multi-station assembly system is analyzed,the relationship of dimension variation propagation in multi-station assembly processes is studied and the state equation for variation propagation is constructed too. Then,the feature parameters which influence variation propagation and accumulation in multi-station assembly processes are found to evaluate quality characteristic of the assembly system. Through the derivation of equation on dimension variation propagation,station coefficient matrices which are combined and conversed to determine the max eigenvalue are educed. The max eigenvalue is multiplied by the weight coefficient to establish the quality evaluation model in multi-station assembly processes. Furthermore,assembly variation indexes are proposed to judge of the assembly technology process. Finally,through the practical example,the application of the model and assembly variation indexes are presented. | Wen Zejun Liu Deshun Yang Shuyi | 2008 | Engineering Sciences2008，6，4： | 0 |
| 12 | Whole‑genome transcriptome and DNA methylation dynamics of pre‑implantation embryos reveal progression of embryonic genome activation in buffaloes显示文摘Background During mammalian pre-implantation embryonic development(PED),the process of maternal-to-zygote transition(MZT)is well orchestrated by epigenetic modification and gene sequential expression,and it is related to the embryonic genome activation(EGA).During MZT,the embryos are sensitive to the environment and easy to arrest at this stage in vitro.However,the timing and regulation mechanism of EGA in buffaloes remain obscure.Results Buffalo pre-implantation embryos were subjected to trace cell based RNA-seq and whole-genome bisulfite sequencing(WGBS)to draw landscapes of transcription and DNA-methylation.Four typical developmental steps were classified during buffalo PED.Buffalo major EGA was identified at the 16-cell stage by the comprehensive analy-sis of gene expression and DNA methylation dynamics.By weighted gene co-expression network analysis,stage-spe-cific modules were identified during buffalo maternal-to-zygotic transition,and key signaling pathways and biological process events were further revealed.Programmed and continuous activation of these pathways was necessary for success of buffalo EGA.In addition,the hub gene,CDK1,was identified to play a critical role in buffalo EGA.Conclusions Our study provides a landscape of transcription and DNA methylation in buffalo PED and reveals deeply the molecular mechanism of the buffalo EGA and genetic programming during buffalo MZT.It will lay a foundation for improving the in vitro development of buffalo embryos. | Penghui Fu Du Zhang Chunyan Yang Xiang Yuan Xier Luo Haiying Zheng Yanfei Deng Qingyou Liu Kuiqing Cui Fei Gao Deshun Shi | 2023 | Journal of Animal Science and Biotechnology2023，14，6： | 0 |
| 13 | Targeting cancer cell plasticity by HDAC inhibition to reverse EBV-induced dedifferentiation in nasopharyngeal carcinoma显示文摘Application of differentiation therapy targeting cellular plasticity for the treatment of solid malignancies has been lagging.Nasopharyngeal carci noma(NPC)is a distinctive cancer with poor differe ntiatio n and high prevalenee of Epstein-Barr virus(EBV)infection.Here,we show that the expressi on of EBV latent protein LMP1 in duces dediffere ntiated and stem-like status with high plasticity through the transcriptional inhibition of CEBPA.Mechanistically,LMP1 upregulates STAT5A and recruits HDAC 1/2 to the CEBPA locus to reduce its histone acetylation.HDAC inhibition restored CEBPA expression,reversing cellular dedifferentiation and stem-like status in mouse xeno graft models.These fin dings provide a novel mecha nistic epigenetic-based in sight into virus-induced cellular plasticity and propose a promising concept of differentiation therapy in solid tumor by using HDAC inhibitors to target cellular plasticity. | Jiajun Xie Zifeng Wang Wenjun Fan Youping Liu Fang Liu Xiangbo Wan Meiling Liu Xuan Wang Deshun Zeng Van Wang Bin He Min Yan Zijian Zhang Mengjuan Zhang Zhijie Hou Chunli Wang Zhijie Kang Wenfeng Fang Li Zhang Eric W-F Lam Xiang Guo Jinsong Yan Yixin Zeng Mingyuan Chen Quentin Liu | 2021 | Signal Transduction and Targeted Therapy2021，6，10： | 0 |
| 14 | A study on resonance Rayleigh scattering spectra of Humic Acid (HA)显示文摘This paper deals with the influences of pH, acidity and ionic intensity of the solutions on the resonance Rayleigh scattering spectra and fluorescence spectra of humic acid. When the pH value is low and the acidity and ionic intensity are high, the resonance Rayleigh spectra and fluorescence spectra both show a tendency of increasing, though the former's intensity is much higher. In combination with the transmission electron microscope data, the factors leading to the occurrence and enhancement of the resonance Rayleigh scattering spectra of humic acid were explored. It is considered that particle enlargement caused by aggregation, the increase of heterogeneity, the increase of hydrophobility, the formation of interface, etc., are the factors leading to the occurrence and enhancement of the resonance Rayleigh scattering spectra of humic acid. As the intensity of the resonance Rayleigh scattering spectra of humic acid is much higher, resonance Rayleigh scattering spectroscopy can be used as a newly developed spectrum technology, which is more sensitive and simpler, to study humic acid and its complicated behaviors. | YU Deshun LIU Shaopu ZHANG Lili ZHU Huiwu TIAN Yifu ZHANG Runyu YANG Jun | 2012 | Chinese Journal Of Geochemistry2012，31，1： | 0 |
| 15 | Modal analysis and pulse response of mobile hard disk head actuator arm assembly显示文摘Head actuator arm assembly (HAA) is the most important mechanical component of a mobile hard disk drive (HDD) and its shock dynamic response is a principal index of vibration resistance. In this paper,a finite element (FE) model is firstly developed in ANSYS of 2.5 inch (1 inch=25.4 mm) mobile hard disk. This model includes actuator arm,voice coil motor (VCM) and pivot bearing. The various step modal of HAA is calculated by FE model. Then the actuator arm vibration behavior is simulated with LS-DYNA procedure. The influence of pulse waveform,pulse amplitude and pulse width on the shock response of the relative displacement of the head actuator arm assembly is studied. | Yang Shuyi Liu Deshun Zhao Jiyun Wen Zejun | 2009 | Engineering Sciences2009，7，3： | 0 |
| 16 | Individual variation in buffalo somatic cell cloning efficiency is related to glycolytic metabolism显示文摘Mammalian individuals differ in their somatic cell cloning efficiency,but the mechanisms leading to this variation is poorly understood.Here we found that high cloning efficiency buffalo fetal fibroblasts(BFFs)displayed robust energy metabolism,looser chromatin structure,high H3 K9 acetylation and low heterochromatin protein 1α(HP1α)expression.High cloning efficiency BFFs had more H3 K9 ac regions near to the upstream of glycolysis genes by Ch IP-seq,and involved more openness loci related to glycolysis genes through ATAC-seq.The expression of these glycolysis genes was also found to be higher in high cloning efficiency BFFs by q RT-PCR.Two key enzymes of glycolysis,PDKs and LDH,were confirmed to be associated with histone acetylation and chromatin openness of BFFs.Treatment of low cloning efficiency BFFs with PS48(activator of PDK1)resulted in an increase in the intracellular lactate production and H3 K9 acetylation,decrease in histone deacetylase activity and HP1αexpression,less condensed chromatin structure and more cloning embryos developing to blastocysts.These results indicate that the cloning efficiency of buffalo somatic cells is associated with their glycolytic metabolism and chromatin structure,and can be improved by increasing glycolytic metabolism. | Chan Luo Zhiqiang Wang Jinling Wang Feng Yun Fenghua Lu Jiayuan Fu Qingyou Liu Deshun Shi | 2022 | Science China(Life Sciences)2022，65，10： | 0 |

| 18 | Stratigraphy and Zircon Provenance of a Late Paleoproterozoic Terrestrial Sequence underlying the Xiong'er Volcanics in the Southern North China Craton显示文摘The late Paleoproterozoic Dagushi Formation comprises a fluvial-lacustrine succession and represents the initial fill of the Xiong'er Basin in the southern North China Craton.Employing integrated outcrop surveys and detrital zircon UPb-Hf dating,this study examines the provenance and depositional setting of the Dagushi Formation.Five major depositional facies,including braided channel,distributary channel,subaqueous stream/mouth bar,pro-delta and shallow lake,were identified,based on lithofacies and associations.They were interpreted as representing a braided river deltalacustrine system.The ages of the last metamorphic event of the basement,covering volcanics and the youngest zircon together constrain a depositional age of ca.1.79 Ga for the Dagushi Formation.Zircon age distributions reveal a provenance change from ca.2.7–2.5 Ga rocks in the lower part,to ca.2.3–1.9 Ga sources in the middle-upper part of the Dagushi Formation.Considering the vertical sedimentology,this provenance change could be induced by the rising water-level caused by a tectonic subsidence.The ca.2.7–2.5 Ga zircons are suggested to be locally sourced from the late Neoarchean–Paleoproterozoic metamorphic basement.The northeast Zhongtiao Mts area(current co-ordinates)is supposed to have appeared as a paleo-uplift and served as a source area for the Paleoproterozoic grains.The Dagushi Formation records an early‘underfilled'stage of the Xiong'er Rift. | SUN Fengbo ZHENG Deshun ZUO Pengfei LIU Weiqing | 2022 | Acta Geologica Sinica(English Edition)2022，96，5： | 0 |
