| 1 | Fault Diagnosis for Manifold Absolute Pressure Sensor(MAP) of Diesel Engine Based on Elman Neural Network Observer显示文摘Intake system of diesel engine is a strong nonlinear system, and it is difficult to establish accurate model of intake system; and bias fault and precision degradation fault of MAP of diesel engine can't be diagnosed easily using model-based methods. Thus, a fault diagnosis method based on Elman neural network observer is proposed. By comparing simulation results of intake pressure based on BP network and Elman neural network, lower sampling error magnitude is gained using Elman neural network, and the error is less volatile. Forecast accuracy is between 0.015?0.017 5 and sample error is controlled within 0?0.07. Considering the output stability and complexity of solving comprehensively, Elman neural network with a single hidden layer and with 44 nodes is presented as intake system observer. By comparing the relations of confidence intervals of the residual value between the measured and predicted values, error variance and failures in various fault types. Then four typical MAP faults of diesel engine can be diagnosed: complete failure fault, bias fault, precision degradation fault and drift fault. The simulation results show: intake pressure is observable and selection of diagnostic strategy parameter reasonably can increase the accuracy of diagnosis;the proposed fault diagnosis method only depends on data and structural parameters of observer, not depends on the nonlinear model of air intake system. A fault diagnosis method is proposed not depending system model to observe intake pressure, and bias fault and precision degradation fault of MAP of diesel engine can be diagnosed based on residuals. | WANG Yingmin ZHANG Fujun CUI Tao ZHOU Jinlong | 2016 | Chinese Journal of Mechanical Engineering2016，29，2： | 17 |
| 2 | Fundamental mechanisms and phenomena of clathrate hydrate nucleation显示文摘Insights into the mechanism of hydrate nucleation are of great significance for the development of hydrate-based technologies,hydrate relevant flow assurance,and the exploration of in situ natural gas hydrates.Compared with the thermodynamics of hydrate formation,understanding the nucleation mechanism is challenging and has drawn substantial attention in recent decades.In this paper,we attempt to give a comprehensive review of the recent progress of studies of clathrate hydrate nucleation.First,the existing hypotheses on the hydrate nucleation mechanism are introduced and discussed.Then,we summarize recent experimental studies on induction time,a key parameter evaluating the velocity of the nucleation process.Subsequently,the memory effect is particularly discussed,followed by the suggestion of several promising research perspectives. | Jinlong Cui Zhenfeng Sun Xiaohui Wang Bin Yu Shudong Leng Guangjin Chen Changyu Sun | 2019 | Chinese Journal of Chemical Engineering2019，27，9： | 11 |
| 3 | Effects of tourmaline on nitrogen removal performance and biofilm structures in the sequencing batch biofilm reactor显示文摘The effects of tourmaline on nitrogen removal performance and biofilm structures were comparatively investigated in two identical laboratory-scale sequencing batch biofilm reactors(SBBRs)(denoted SBBR1 and SBBR2) at different nitrogen loading rates(NLRs) varying from(0.24 ± 0.01) to(1.26 ± 0.02) g N/(L·day). SBBR1 was operated in parallel with SBBR2, but SBBR1 was filled with polyurethane foam loaded tourmaline(TPU) carriers and another(SBBR2) filled with polyurethane foam(PU) carriers. Results obtained from this study showed that the excellent and stable performance of SBBR1 was obtained. Ammonia nitrogen removal and total nitrogen removal were higher in SBBR1 than that in SBBR2 with increase of NLR. At an NLR of(0.24 ± 0.01) g N/(L·day), the majority of the spherical and elliptical bacteria were surrounded by the extracellular polymeric substance(EPS) and bacillus or filamentous bacteria in two SBBRs biofilms. When NLR increased to(1.26 ± 0.02) g N/(L·day), the clusters were more obvious in the SBBR1 biofilm than that in the SBBR2 biofilm. Bacteria in SBBR1 were inclined to synthesis more EPS, and the formed EPS could protect the bacteria from free ammonia(FA) under extreme condition NLR(1.26 ± 0.02) g N/(L·day). The results of polymerase chain reaction-denaturing gradient gel electrophoresis analysis showed that the microbial community similarity in SBBR2 decreased more obviously than that in SBBR1 with the increase of NLR, which the microbial community in SBBR1 was relatively stable. | Chong Tan Haoran Xu Di Cui Jinlong Zuo Junsheng Li Yubin Ji Shan Qiu Lin Yao Ying Chen Yingjie Liu | 2018 | Journal of Environmental Sciences2018，30，5： | 10 |
| 4 | Diluted ferromagnetic semiconductor(LaCa)(ZnMn)SbO isostructural to “1111” type iron pnictide superconductors显示文摘We report discovery of ferromagnetism in(LaCa)(ZnMn)SbO isostructural to the well-studied iron-based superconductor LaFeAs(O1 xFx).Spin is induced by partial substitution of Mn2+for Zn2+,while charge is induced by substitution of Ca2+for La3+within the parent compound LaZnSbO.Ferromagnetism with Curie temperature(TC)is observed up to 40 K at the spin doping 0.15 by introducing Mn2+into the Zn2+sites for(La0.95Ca0.05)(Zn1 xMnx)SbO.The Hall coefficient measurement indicates p-type carrier for(La0.95Ca0.05)(Zn0.9Mn0.1)SbO with concentration of n^1020cm 3showing anomalous Hall effect below TC. | HAN Wei ZHAO Kan WANG XianCheng LIU QingQing NING FanLong DENG Zheng LIU Ying ZHU JinLong DING Cui MAN HuiYuan JIN ChangQing | 2013 | Science China(Physics,Mechanics & Astronomy)2013，56，11： | 8 |
| 5 | Effects of inoculating fungi on agilawood formation in Aquilaria sinensis显示文摘Agilawood is a costly heartwood medicine obtained from Aquilaria sinensis with active ingredients mainly composed of volatile and semi-volatile substances. However, the formation time of agilawood is quite long and little is known about its formation mechanism. Two highly active fungi obtained from natural agilawood were inoculated on A. sinensis trees to understand their interaction processes and elucidate the transformation rules of induced chemical compositions within different test periods. The results demonstrated that the fungi could successfully colonize living tissues and cells and activate the host defense system, resulting in agilawood accumulation. With increasing time, the main components of A. sinensis converted into constituents or analogs of agilawood and the host exhibited 'self-injury' to prevent fungal intrusion and protect other tissues. The data presented here could provide scientific basis for producing agilawood with the two new fungi in a safe, feasible, and sustainable manner without destroying rare Aquilaria plants. | CUI JinLong GUO ShunXing FU ShaoBin XIAO PeiGen WANG MengLiang | 2013 | Chinese Science Bulletin2013，58，26： | 8 |
| 6 | In vitro and in vivo biodegradation and biocompatibility of an MMT/BSA composite coating upon magnesium alloy AZ31显示文摘The performance of biodegradable magnesium alloy requires special attention to rapid degradation and poor biocompatibility, which can cause the implant to fail. Here, a sodium montmorillonite(MMT)/bovine serum albumin(BSA) composite coating was prepared upon magnesium alloy AZ31 via hydrothermal synthesis, followed by dip coating. We evaluated the surface characterization and corrosion behavior in vitro, and the biocompatibility in vitro and in vivo. Biodegradation progress of the MMT-BSA coated Mg pieces was examined through hydrogen evolution, immersion tests, and electrochemical measurements in Hank’s solution. In vitro biocompatibility studies were evaluated via hemolysis tests, dynamic cruor time tests, platelet adhesion, MTT testing and live-dead stain of osteoblast cells(MC3 T3-E1). It was found that the MMT-BSA coating had good corrosion resistance and a marked improvement in biocompatibility in comparison to bare Mg alloy AZ31. in vivo studies were carried out in rat model and the degradation was characterized by computed tomography scans. Results revealed that the MMT-BSA coated Mg alloy AZ31 implants maintained their structural integrity and slight degradation after 120 d of post-implantation. A100% survival rate for the rats was observed with no obvious toxic damages on the organs and tissues.Additionally, we proposed a sound coating formation mechanism. Considering the good corrosion protection and biocompatibility, the MMT-BSA coated Mg alloy AZ31 is a promising candidate material for biomedical implants. | Jian Wang Lanyue Cui Yande Ren Yuhong Zou Jinlong Ma Chengjian Wang Zhongyin Zheng Xiaobo Chen Rongchang Zeng Yufeng Zheng | 2020 | Journal of Materials Science & Technology2020，47，12： | 7 |
| 7 | Comparative analysis of four essential Gracilariaceae species in China based on whole transcriptomic sequencing显示文摘Three Gracilaria species,G.chouae,G.blodgettii,G.vermiculophylla and a close relative species,Gracilariopsis lemaneiformis which is now nominated as Gracilaria lemaneiformis,are the typically indigenous species which are important resources for the production of special proteins,phycobilisomes,special carbohydrates,and agar in China.In this study,de novo transcriptome sequencing on these four species using the next generation sequencing technology was performed for the first time.Functional annotations on assembled sequencing reads showed that the transcriptomic profiles were quite different between G.lemaneiformis and other three Gracilaria species.Comparative analysis of differential gene expression related to carbohydrate and phycobiliprotein metabolisms also showed that the expression profiles of these essential genes were different in four species.The genes encoding allophycocyanin,phycocyanin and phycoerythrin were further examined in four species and their deduced amino acid sequences were used for phylogenetic analysis to confirm that G.lemaneiformis had close relationship to genus Gracilaria,as well as that within genus Gracilaria,G.chouae had closer relationship to G.vermiculophylla rather than to G.blodgettii.The de novo transcriptome study on four species provided a valuable genomic resource for further understanding and analysis on biological and evolutionary study among marine algae. | XU Jiayue SUN Jing YIN Jinlong WANG Liang WANG Xumin LIU Tao CHI Shan LIU Cui REN Lufeng WU Shuangxiu YU Jun | 2014 | Acta Oceanologica Sinica2014，33，2： | 3 |
| 8 | Preparation and characterization of microcrack-free thick YBa_2Cu_3O_(7-δ) films显示文摘High quality epitaxial YBa2Cu3O7-δ (YBCO) superconducting films were fabricated on (00l) LaAlO3 substrates using the direct-current sputtering method. The attainment of an unusually high film thickness (up to 2.0 μm) without mi-crocracking was attributed in part to the presence of pores correlated with yttrium-rich composition in the films. The influ-ence of the film thickness on the microstructure was investigated by X-ray diffraction conventional scan (θ-2θ,ω-scan,pole figure) and high-resolution reciprocal space mapping. The films were c-axis oriented with no a-axis-oriented grains up to the thickness of 2 μm. The surface morphology and the critical current density (Jc) strongly depended on the film thickness. Furthermore,the reasons for these thickness dependences were elucidated in detail. | XIONG Jie QIN Wenfeng TANG Jinlong TAO Bowan CUI Xumei LI Yanrong | 2007 | Rare Metals2007，26，5： | 3 |
| 9 | Eco-compensation of Wetlands in Yellow River Delta of Shandong Province,China显示文摘Wetlands play an important ecological role and provide many functions for people,yet wetlands are cur-rently decreasing and deteriorating.The ability to calculate an economic value for the loss of wetlands is becoming in-creasingly important for policy makers.In this study,remote sensing,field investigations,department visits,and other methods were used to survey wetland types,assess wetland area changes,and calculate wetland economic value.Mar-ket value loss and ecological function value loss,caused by reduction of wetland area and environmental pollution were calculated using commonly accepted methods of market valuation,ecological valuation,environmental protection investment cost analysis,and outcome parameters.According to market value loss and ecological function value loss,preliminarily fund allocation for wetland and ecological compensation was calculated.This will provide an important reference for future Yellow River Delta eco-compensation studies. | HAN Mei CUI Jinlong HAO Zhen WANG Yi WANG Renqing | 2012 | Chinese Geographical Science2012，22，1： | 3 |
| 10 | Polycrystalline diamond MESFETs by Au-mask technology for RF applications显示文摘Metal-semiconductor field effect transistors (MESFETs) were fabricated on H-terminated polycrystalline diamond.The DC characteristics of the p-channel MESFET showed a maximum drain current density of 204 mA/mm at a gate-source voltage of 6 V,and a maximum transconductance of 20 mS/mm at a gate-source voltage of 1.5 V.The small signal S-parameters of MESFET with 2 100 m gate width and 2 m gate length were measured.An extrinsic cut-off frequency (fT) of 1.7 GHz and the maximum oscillation frequency (fmax) of 2.5 GHz were obtained,which was the first report on diamond MESFETs with RF characteristics in China. | FENG ZhiHong WANG JingJing HE ZeZhao DUN ShaoBo YU Cui LIU JinLong ZHANG PingWei GUO Hui LI ChengMing CAI ShuJun | 2013 | Science China(Technological Sciences)2013，56，4： | 2 |
| 11 | Commutative regulation between endothelial NO synthase and insulin receptor substrate 2 by microRNAs显示文摘Endothelial NO synthase (eNOS) expression is regulated by a number of transcriptional and post-transcriptional mechanisms, but the effects of competing endogenous RNAs (ceRNAs) on eNOS mRNA and the underlying mechanisms are still unknown. Our bioinformatic analysis revealed three highly expressed eNOS-targeting miRNAs (miR-15b, miR-16, and miR-30b) in human endothelial cells (ECs). Among the 1103 mRNA targets of these three miRNAs, 15 mRNAs share a common disease association with eNOS. Gene expression and correlation analysis in patients with cardiovascular diseases identified insulin receptor substrate 2 (IRS2) as the most correlated eNOS-ceRNA. The expression levels of eNOS and IRS2 were coincidentally increased by application of laminar shear but reduced with eNOS or IRS2 siRNA transfection in human ECs, which was impeded by Dicer siRNA treatment. Moreover, luciferase reporter assay showed that these three miRNAs directly target the 3′UTR of eNOS and IRS2. Overexpression of these three miRNAs decreased, whereas inhibition of them increased, both mRNA and protein levels of eNOS and IRS2. Functionally, silencing eNOS suppressed the Akt signal pathway, while IRS2 knockdown reduced NO production in ECs. Thus, we identified eNOS and IRS2 as ceRNAs and revealed a novel mechanism explaining the coincidence of metabolic and cardiovascular diseases. | Xiaoli Sun Huizhen Lv Peng Zhao Jinlong He Qinghua Cui Minxin Wei Shiqing Feng Yi Zhu | 2019 | Journal of Molecular Cell Biology2019，11，6： | 2 |
| 12 | High efficient development of green kinetic hydrate inhibitors via combined molecular dynamic simulation and experimental test approach显示文摘The development of environmental friendly low dose hydrate inhibitors like kinetic hydrate inhibitors(KHIs)is of great significance for the flow assurance in oil&gas production and transportation.In this work,a combined molecular dynamic simulation and experimental verification approach was adopted to increase the efficiency of KHIs development.The inhibition effect of a series of copolymers(N-vinylpyrrolidone and N-acrylate)on hydrate growth was studied by using both molecular dynamics simulation and experimental approaches.The simulation results demonstrated that introduction of hydrophobic ester and butyl group in PVP is beneficial for the inhibition.The length of the alkyl chain of ester group played an important role in improving inhibition performance.PVP-A,the one being introduced butyl ester group into PVP gets the best inhibition effect.In addition,inhibitors can restrict methane bubbles to re-dissolve into the liquid phase,thereby inhibiting the growth of methane hydrate.Increasing the interaction between KHIs and methane can also improve the inhibitory effect of KHIs.The experimental results confirm the reliability of the molecular dynamics simulation. | Liwei Cheng Jinlong Cui Jia Li Ran Zhu Bei Liu Shuai Ban Guangjin Chen | 2022 | Green Chemical Engineering2022，3，1： | 2 |
| 13 | Value of partial hepatectomy for the treatment of hilar cholangiocarcinoma: a Meta-analysis study显示文摘Objective To discuss the value of partial hepatectomy in patients with hilar cholangiocarcinoma.Methods English articles related to hilar cholangiocarcinoma were screened from January 1,1990 to May 12,2019 in the Pub Med,MEDLINE,EMBASE,and Cochrane Library databases.Information on postoperative radical cure,survival,morbidity,and mortality after surgery were extracted from articles that met the inclusion criteria for the meta-analysis.Results Twenty-two articles that met the inclusion criteria were classified into 4 study groups: the hepatectomy radical cure group(19 articles),the hepatectomy survival group(16 articles),the hepatectomy morbidity group(9 articles),and the hepatectomy mortality group(17 articles).We found that the rate of radical cure after partial hepatectomy(odds ratio [OR] 0.32,95% confidence interval [CI] 0.20-0.51) and the survival rate(hazard ratio [HR] 0.67,95% CI 0.58-0.79) were significantly higher than after simple bile duct resection,but that morbidity(OR 1.99,95% CI 1.37-2.90) and mortality(OR 2.71,95% CI 1.47-4.98) in patients within the partial hepatectomy group were also higher than in the simple bile duct resection group,taking into account the significant heterogeneity in the articles pertaining to the hepatectomy radical cure group(I^2=68.3%,P=0.000),a sub-group analysis was subsequently conducted.Its results showed that when the branches of the secondary bile ducts were not involved during hilar cholangiocarcinoma,then a bile duct resection had a similar radical cure outcome as combined partial hepatectomy(OR 0.94,95% CI 0.54-1.65).Conclusion Partial hepatectomy can increase the proportion of radical cure in patients with hilar cholangiocarcinoma and extend the survival time after surgery.However,the morbidity and mortality after surgery are higher than those in simple bile duct resections.Therefore,simple bile duct resection is still a relevant and efficient tool in the treatment of Bismuth-Corlette Type Ⅰ and Ⅱ hilar cholangiocarcinomas. | Ming Yang Yanhong Zhang Miaohang Cui Jianhua Chen JinLong Liu | 2019 | Oncology and Translational Medicine2019，5，6： | 1 |

| 15 | De novo sequencing and comparative analysis of three red algal species of Family Solieriaceae to discover putative genes associated with carrageenan biosysthesis显示文摘Betaphycus gelatinus,Kappaphycus alvarezii and Eucheuma denticulatum of Family Solieriaceae,Order Gigartinales,Class Rhodophyceae are three important carrageenan-producing red algal species,which produce different types of carrageenans,beta(β)-carrageenan,kappa(κ)-carrageenan and iota(ι)-carrageenan.So far the carrageenan biosynthesis pathway is not fully understood and few information is about the Solieriaceae genome and transcriptome sequence.Here,we performed the de novo transcriptome sequencing,assembly,functional annotation and comparative analysis of these three commercial-valuable species using an Illumina short-sequencing platform Hiseq 2000 and bioinformatic software.Furthermore,we compared the different expression of some unigenes involved in some pathways relevant to carrageenan biosynthesis.We finally found 861 different expressed KEGG orthologs which contained a glycolysis/gluconeogenesis pathway(21 orthologs),carbon fixation in photosynthetic organisms(16 orthologs),galactose metabolism(5 orthologs),and fructose and mannose metabolism(9 orthologs) which are parts of the carbohydrate metabolism.We also found 8 different expressed KEGG orthologs for sulfur metabolism which might be importantly related to biosynthesis of different types of carrageenans.The results presented in this study provided valuable resources for functional genomics annotation and investigation of mechanisms underlying the biosynthesis of carrageenan in Family Solieriaceae. | SONG Lipu WU Shuangxiu SUN Jing WANG Liang LIU Tao CHI Shan LIU Cui LI Xingang YIN Jinlong WANG Xumin YU Jun | 2014 | Acta Oceanologica Sinica2014，33，2： | 1 |
| 16 | Endogenous viral elements in algal genomes显示文摘Endogenous viral elements(EVEs) are host-genomic fragments originated from viral genomes.They have been found universally in animal and plant genomes.Here we carried out a systematic screening and analysis of EVEs in algal genomes and found that EVEs commonly exist in algal genomes.We classified the EVE fragments into three categories according to the length of EVE fragments.Due to the probability of sequence similarity by chance,we ignored the potential function of medium-length EVE fragments.However,longlength EVE fragments probably had capability to encode protein domains or even entire proteins,and some short-length EVE fragments had high similarity with host's siRNA sequences and possibly served functions of small RNAs.Therefore,short and long EVE fragments might provide regulomic and proteomic novelty to the host's metabolism and adaptation.We also found several EVE fragments shared by more than 3 algal genomes.By phylogenetic analysis of the shared EVEs and their corresponding species,we found that the integration of viral fragments into host genomes was an ancient event,possibly before the divergence of Chlorophytes and Ochrophytes.Our findings show that there is a frequent genetic flow from viruses to algal genomes.Moreover,study on algal EVEs shed light on the virus-host interaction in large timescale and could also help us understand the balance of marine ecosystems. | WANG Liang WU Shuangxiu LIU Tao SUN Jing CHI Shan LIU Cui LI Xingang YIN Jinlong WANG Xumin YU Jun | 2014 | Acta Oceanologica Sinica2014，33，2： | 1 |

| 19 | Performance of Nb_(0.8)Zr_(0.2) Layer-Modified AISI430 Stainless Steel as Bipolar Plates for Direct Formic Acid Fuel Cells显示文摘To improve the interfacial conductivity and corrosion resistance of AISI430 stainless steel(430 SS)as bipolar plates for direct formic acid fuel cells(DFAFCs),a Nb_(0.8)Zr_(0.2) layer has been successfully synthesized via the pulsed laser deposition(PLD)technique on the surface of 430 SS.This Nb_(0.8)Zr_(0.2) layer is smooth,uniform,and comparatively compact without any surface flaw and micropore.Investigation under the simulated anodic environment of DFAFCs(0.05 M H_(2)SO_(4)+2 ppm HF+10 M HCOOH at 70℃)shows that the corrosion resistance of 430 SS is obviously ameliorated after the PLD modification.In addition,the interfacial contact resistance of Nb_(0.8)Zr_(0.2)-430 SS(6.0 mΩcm^(2))is much smaller than that of bare 430 SS(151.3 mΩcm^(2))at the clamping force of 140 N cm^(-2).Besides,diff erent from the highly increased interfacial contact resistance of bare 430 SS,the Nb_(0.8)Zr_(0.2)-430 SS shows a minor increase resistance after potentiostatic tests in simulated anodic environment of DFAFCs. | Yuanyuan Liu Zhongmin Lang Jinlong Cui Shengli An | 2021 | Acta Metallurgica Sinica(English Letters)2021，34，1： | 1 |
