1The spatial distribution of forest carbon sinks and sources in China显示文摘Forest ecosystems play an important role in the global carbon cycle.The implementation of the United Nations Framework Convention on Climate Change(UNFCCC) and the Kyoto Protocol has made the study of forest ecosystem carbon cycling a hot topic of scientific research globally.This paper utilized Chinese national forest inventory data sets(for the periods 1984-1988 and 1999-2003),the vegetation map of China(1:1000000),and the spatially explicit net primary productivity(NPP) data sets derived with the remote sensing-based light use efficiency model(CASA model).We quantitatively estimated the spatial distribution of carbon sinks and sources of forest vegetation(with a resolution of 1 km) using the spatial downscaling technique.During the period 1984 to 2003 the forest vegetation in China represented a carbon sink.The total storage of carbon increased by 0.77 PgC,with a mean of 51.0TgCa 1.The total carbon sink was 0.88PgC and carbon source was 0.11 PgC during the study period.The carbon sink and carbon source of forest vegetation in China showed a clear spatial distribution pattern.Carbon sinks were mainly located in subtropical and temperate regions,with the highest values in Hainan Province,Hengduan mountain ranges,Changbai mountain ranges in Jilin,and south and northwest of the Da Hinggan Mountains;carbon sources were mainly distributed from the northeast to southwestern areas in China,with the highest values mainly concentrated in southern Yunnan Province,central Sichuan Basin,and northern Da Hinggan Mountains.Increase in NPP was strongly correlated with carbon sink strength.The regression model showed that more than 80% of the variation in the modeled carbon sinks in Northeast,Northern,Northwest and Southern China were explained by the variation in NPP increase.There was a strong relationship between carbon sink strength and forest stand age.LIU ShuangNa ZHOU Tao WEI LinYan SHU Yang 2012Chinese Science Bulletin2012,57,14:27
2High-resolution geochemistry records of climate changes since late-glacial from Dajiuhu peat in Shennongjia Mountains,Central China显示文摘A peat core with depths of 297 cm was obtained from the Dajiuhu Basin(31°29′27″N,109°59′45″E,1760 m)in Hubei Province,Central China.10 AMS ages provide a time control and reveal that this core spans the past about 16.0 kaBP(calibrated age)(1 4C age:13.3 kaBP).Multi-proxy indexes analysis of geochemistry shows the following character of climate and environmental changes since about 16 kaBP:(1) The climate during the late-glacial period was cold and wet as a whole,but fluctuated continually.11.4- 12.6 cal.kaBP,12.6-15.2 cal.kaBP and 15.2-16 kaBP were corresponding respectively to the Younger Drays,Bφlling-Allerφd Warm Period and the Oldest Drays.(2)Inheriting the some climate characteristics of the late-glacial,the climate during the early-Holocene was wet and temperature increased gradually,during which an obvious dry event around 10.6 cal.kaB appeared.(3)The climate during the mid-Holocene was genarally warm and wet.During 9.2-7.5 kaBP,temperature increased gradually, precipitation was less comparatively and the 8.2 kaBP cold event which might be representative in the globe was reflected markedly.Then,multi-proxy records were relatively stable during 6.7-4.2 kaBP, which shows the best water and thermal condition in the Holocene Optimum.(4)Around 4.2 kaBP,the climate and environment transform from warm and wet to cool and dry,which may result in the collapse of the Neolithic Culture and midwifery the civilization of Xia Dynasty in this region.After 0.9 kaBP,the climate turned cool and wet.Climate and environmental changes archived in Dajiuhu peat respond to the global changes since the late-glacial period and can be contrasted to the changes recorded in other high-resolution archives from the East Asia Monsoon region,which take on the variety model that the monsoon strengthened abruptly after the late-glacial,was strong during the early Holocene,subse- quently declined and became weak after the middle Holocene with dry climate.According to our analysis,the driving mechanism should be the response of solar radiation changes in the East Asia Monsoon region at middle latitudes.MA ChunMei ZHU Cheng ZHENG ChaoGui WU ChunLin GUAN Yong ZHAO ZhiPing HUANG LinYan HUANG Run 2008Chinese Science Bulletin2008,53,S1:19

4Synthesis and adsorption performance of lead ion-imprinted micro-beads with combination of two functional monomers显示文摘A novel ion-imprinted polymer, lead ion-imprinted micro-beads with combination of two functional monomers,was synthesized using the W/O/W polymerization method. Two functional monomers, 1,12-dodecanediol-O,O’-diphenyl-phosphonic acid (DDDPA) and 4-vinylpyridine, were used to form a suitable construction with micro-pores fitting the template and recognition sites. The eflectsof adsorbent dosage, solution pH and the competitive ions on the adsorption and separation eflciency of lead ions were investigated.The lead ion-imprinted micro-beads were eflcient for lead ions removal from aqueous solution in a broad pH range (4–9), when theadsorbent dosage was above 0.1 g/L. The adsorption process obeyed the pseudo second-order kinetics model and it only took half anhour to reach the equilibrium. The adsorption isotherm of lead ion was described by the Langmuir model (R2 >0.99) with a maximumadsorption capacity of 116.9 mg/g. In the presence of competitive ions Co2+ and Cd2+, the lead ion-imprinted micro-beads showed ahigh selectivity for lead ions. The selectivity coefficient of Pb2+/Cd2+ and Pb2+/Co2+are 99.3 and 114.7, respectively.Linyan Zhu Zhiliang Zhu Ronghua Zhang Jun Hong Yanling Qiu 2011Journal of Environmental Sciences2011,23,12:9
5Isolation and characterization of heterotrophic nitrifying bacteria in MBR显示文摘The study presented the method for isolating the heterotrophic nitrifiers and the characterization of heterotrophic nitrification. Continuous tests via a membrane bioreactor (MBR) were operated under the controlled conditions to proliferate the nitrifiers. Heterotrophic nitrifying bacteria were isolated from the system in which the efficiency of total nitrogen(TN) removal was up to 80%. Since no autotrophic ammonium and nitrite oxidizers could be detected by fluorescence in situ hybridization(FISH), oxidized-N production was unlikely to be catalyzed by autotrophic nitrifiers during the heterotrophic nitrifiers’ isolation in this study. The batch test results indicate that the isolated heterotrophic bacteria were able to nitrify. After 3 weeks incubation, the efficiencies of the COD removal by the three isolated bacterial strains B1, B2, and B3 were 52 6%, 71 7%, and 77 7%, respectively. The efficiencies of the TN removal by B1, B2, and B3 were 35 6%, 61 2% and 68 7%, respectively.LINYan HEYi-liang KONGHai-nan LIUBin-bin LIYan INAMONYuhei 2005Journal of Environmental Sciences2005,17,4:7
6PRICE AND SERVICE COMPETITION WITH MAINTENANCE SERVICE BUNDLING显示文摘In many equipment manufacturing industries,firms compete with each other not only on products price,but also on maintenance service.More and more traditional products oriented firms are offering their customers products bundled with maintenance service(P&S bundles).In this study,we examine firms' incentive to offer customers products bundling with long-term maintenance or repair support service in a duopoly competitive environment.When providing P&S bundles,a firm need to determine the service level(in terms of average response time guarantee for the service in this paper) to offer and needs to build a service facility to handle the maintenance service requirements.Based on the analysis of three sub-game models,we characterize the market conditions in which only one firm,both firms or neither firm will offer P&S bundles.Finally,we analyze the affects of serval market factors on firms' strategy choices.Yi Wang Linyan Sun Rong Qu Gang Li 2015Journal of Systems Science and Systems Engineering2015,24,2:6
7NDRG4 prevents cerebral ischemia/reperfusion injury by inhibiting neuronal apoptosis显示文摘Cerebral ischemia is a major cause of mortality and long-term morbidity worldwide.NDRG4 has been shown to protect against cerebral ischemia,although the underlying mechanisms remain largely unclear.Here we found that NDRG4 expression was decreased in the brain tissues of ischemia/reperfusion(IR)rats,indicating increased apoptosis rates among cerebral cells.NDRG4 restoration via an adenovirus significantly attenuated cerebral infarct sizes and impairments in IR rats.Furthermore,adenovirus-mediated NDRG4 inhibited cell apoptosis in the brains of IR rats and regulated the expression of Bcl-2,Bax,caspase-3,and c-Fos.Moreover,we found that NDRG4 increased expression of BDNF,which is strongly related to cerebral ischemia and cellular apoptosis.Altogether,our findings demonstrate that NDRG4 protects cerebral IR injury by inhibiting cell apoptosis and regulates cerebral cell apoptosis by increasing BDNF expression.These results suggest that NDRG4 may be a therapeutic target for IR treatment.Lan Wen Lei Liu Linyan Tong Jinfang Li Keming Zhang Qinbin Zhang Changqing Li 2019Genes & Diseases2019,6,4:6
8Research on global change scientific satellites显示文摘Global change now poses a severe threat to the survival and development of mankind.Large-scale,real-time,highly accurate Earth observation from space has become a key technology used to observe global change.China is one of the most influential countries affecting and being affected by global change,yet it has no scientific satellite for global change research so far.Developing global change scientific satellites not only would meet an important demand of China,but also would be a valuable contribution to the world.By analyzing the mechanisms of space-based observation of variables sensitive to global change,this paper explores the concept of global change scientific satellites,and proposes a series of global change scientific satellites to establish a scientific observation system for global environmental change monitoring from space.GUO HuaDong FU WenXue LI XinWu CHEN Pei LIU Guang LI Zhen WANG Cheng DONG Qing LEI LiPing BAI LinYan LIU QingJie 2014Science China Earth Sciences2014,57,2:5
9Aberrant Resting-State Functional Connectivity in the Default Mode Network in Pediatric Bipolar Disorder Patients with and without Psychotic Symptoms显示文摘Mood disorders/psychosis have been associated with dysfunctions in the default mode network(DMN).However,the relative contributions of DMN regions to state and trait disturbances in pediatric bipolar disorder(PBD)remain unclear.The aim of this study was to investigate the possible mechanisms of PBD through brain imaging and explore the influence of psychotic symptoms on functional alterations in PBD patients.Twenty-nine psychotic and 26 non-psychotic PBD patients,as well as 19 age-and sex-matched healthy controls underwent a restingstate functional MRI scan and the data were analyzed by independent component analysis.The DMN component from the fMRI data was extracted for each participant.Spearman's rank correlation analysis was performed between aberrant connectivity and clinical measurements.The results demonstrated that psychotic PBD was characterized by aberrant DMN connectivity in the anterior cingulate cortex/medial prefrontal cortex,bilateral caudate nucleus,bilateral angular gyri,and left middle temporal gyrus,while non-psychotic PBD was not,suggesting further impairment with the development of psychosis.In summary,we demonstrated unique impairment in DMN functional connectivity in the psychotic PBD group.These specific neuroanatomical abnormalities may shed light on the underlying pathophysiology and presentation of PBD.Yuan Zhong Chun Wang Weijia Gao Qian Xiao Dali Lu Qing Jiao Linyan Su Guangming Lu 2019Neuroscience Bulletin2019,35,4:5
10Shift control method for the local time at descendi ngnode based on sun-synchronous orbit satellite显示文摘This article analyzes the shift factors of the descending node local time for sun-synchronous satellites and proposes a shift control method to keep the local time shift within an allowance range. It is found that the satellite orbit design and the orbit injection deviation are the causes for the initial shift velocity, whereas the atmospheric drag and the sun gravitational perturbation produce the shift acceleration. To deal with these shift factors, a shift control method is put forward, through such methods as orbit variation design, orbit altitude, and inclination keeping control. The simulation experiment and practical application have proved the effectiveness of this control method.Yang Yong'an Feng Zuren Sun Linyan Tan Wei 2009Journal of Systems Engineering and Electronics2009,20,1:5

12Bacillus licheniformis PF9 improves barrier function and alleviates inflammatory responses against enterotoxigenic Escherichia coli F4 infection in the porcine intestinal epithelial cells显示文摘Background:Enterotoxigenic Escherichia coli(ETEC)F4 commonly colonizes the small intestine and releases enterotoxins that impair the intestinal barrier function and trigger inflammatory responses.Although Bacillus licheniformis(B.licheniformis)has been reported to enhance intestinal health,it remains to be seen whether there is a functional role of B.licheniformis in intestinal inflammatory response in intestinal porcine epithelial cell line(IPEC-J2)when stimulated with ETEC F4.Methods:In the present study,the effects of B.licheniformis PF9 on the release of pro-inflammation cytokines,cell integrity and nuclear factor-κB(NF-κB)activation were evaluated in ETEC F4-induced IPEC-J2 cells.Results:B.licheniformis PF9 treatment was capable of remarkably attenuating the expression levels of inflammation cytokines tumor necrosis factor-α(TNF-α),interleukin(IL)-8,and IL-6 during ETEC F4 infection.Furthermore,the gene expression of Toll-like receptor 4(TLR4)-mediated upstream related genes of NF-κB signaling pathway has been significantly inhibited.These changes were accompanied by significantly decreased phosphorylation of p65 NF-κB during ETEC F4 infection with B.licheniformis PF9 treatment.The immunofluorescence and western blotting analysis revealed that B.licheniformis PF9 increased the expression levels of zona occludens 1(ZO-1)and occludin(OCLN)in ETEC F4-infected IPEC-J2 cells.Meanwhile,the B.licheniformis PF9 could alleviate the injury of epithelial barrier function assessed by the trans-epithelial electrical resistance(TEER)and cell permeability assay.Interestingly,B.licheniformis PF9 protect IPEC-J2 cells against ETEC F4 infection by decreasing the gene expressions of virulence-related factors(including luxS,estA,estB,and elt)in ETEC F4.Conclusions:Collectively,our results suggest that B.licheniformis PF9 might reduce inflammation-related cytokines through blocking the NF-κB signaling pathways.Besides,B.licheniformis PF9 displayed a significant role in the enhancement of IPEC-J2 cell integrity.Qiao Li Linyan Li Yanhong Chen Changning Yu Paula Azevedo Joshua Gong Chengbo Yang 2022Journal of Animal Science and Biotechnology2022,13,5:4
13Synthesis,characterization and cell imaging properties of rare earth compounds based on hydroxamate ligand显示文摘Six binuclear rare earth compounds were synthesized through the ligand of 4-Bromo-N-hydroxy-Nmethyl-benzamide(sH_2 bha). Compounds 1-3 are isomorphous, and compound 1 is crystallized in the monoclinic system with the P2_1/c space group. Compounds 4 and 5 are isomorphous, and compound 4 is crystallized in the triclinic system with the P-1 space group. Compound 6 is crystallized in the triclinic system with the P-1 space group. The compounds were characterized by thermogravimetric analysis(TGA) and IR spectroscopy. The fluorescence spectrum in the visible area shows characteristic peaks of Eu, Tb, and Dy compounds. The efficiency of Eu compound on the viability of PC3 cells was assessed using CCK8 assays. From the CCK8 results, ionic concentration may have a great effect on PC3 cells' proliferation. Eu compound shows red fluorescence in the cytoplasm of PC3 cell. As for Eu compound, it might have potential application in cell imaging technology.Linyan Yang Yanping Zhang Liwei Hu Yunhe Zong Ruili Zhao Tianming Jin Wen Gu 2018Journal of Rare Earths2018,36,4:3

15Identifying absorbable bioactive constituents of Yupingfeng Powder acting on COVID-19 through integration of UPLC-Q/TOF-MS and network pharmacology analysis显示文摘Objective:Yupingfeng Powder(YPF),a kind of preventative patent medicine,is chosen for treatment of coronavirus disease 2019(COVID-19)due to its high frequency application in respiratory tract diseases,such as chronic obstructive pulmonary disease,asthma,respiratory tract infections,and pneumonia,with the advantage of reducing the relapse rate and the severity.However,the active components of YPF and the mechanisms of components affecting COVID-19 are unclear.This study aimed to determine active constituents and elucidate its potential mechanisms.Methods:Ultra performance liquid chromatography-quadrupole-time of flight mass spectrometry(UPLCQ/TOF-MS)and liquid chromatography-triple quadrupole mass spectrometry(LC-QQQ-MS)were used to determine the components and absorbable constituents of YPF.Secondly,TCMSP,Drugbank,Swiss and Pharm Mapper were used to search the targets of absorbable bioactive constituents of YPF,and the targets of COVID-19 were identified based on Gene Cards and OMIM databases.STRING database was used to filter the possible inter-protein interactions.Thirdly,Gene Ontology(GO)enrichment analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathways analysis were performed to identify molecular function and systemic involvement of target genes.Results:A total of 61 components of YPF and 36 absorbable constituents were identified through UPLC-Q/TOF-MS.Wogonin,prim-O-glucosylcimifugin,5-O-methylvisamminol,astragalosideⅣand 5-Omethylvisamminol(hydroxylation)were vital constituents for the treatment of COVID-19,and RELA,TNF,IL-6,MAPK14 and MAPK8 ere recognized as key targets of YPF.The major metabolic reactions of the absorbed constituents of YPF were demethylation,hydroxylation,sulfation and glucuronidation.GO and KEGG pathway analysis further showed that the most important functions of YPF were T cell activation,response to molecule of bacterial origin,cytokine receptor binding,receptor ligand activity,cytokine activity,IL-17 signaling pathway,Chagas disease,lipid and atherosclerosis,etc.Conclusion:The approach of combining UPLC-Q/TOF-MS with network pharmacology is an effective tool to identify potentially bioactive constituents of YPF and its key targets on treatment of COVID-19.Linyan Wang Zhongyan Du Yang Guan Bo Wang Yanling Pei Lizong Zhang Mingsun Fang 2022Chinese Herbal Medicines2022,14,2:3
16Multi-label Image Classification via Coarse-to-Fine Attention显示文摘Great efforts have been made by using deep neural networks to recognize multi-label images.Since multi-label image classification is very complicated,many studies seek to use the attention mechanism as a kind of guidance.Conventional attention-based methods always analyzed images directly and aggressively,which is difficult to well understand complicated scenes.We propose a global/local attention method that can recognize a multi-label image from coarse to fine by mimicking how human-beings observe images.Our global/local attention method first concentrates on the whole image,and then focuses on its local specific objects.We also propose a joint max-margin objective function,which enforces that the minimum score of positive labels should be larger than the maximum score of negative labels horizontally and vertically.This function further improve our multi-label image classification method.We evaluate the effectiveness of our method on two popular multi-label image datasets(i.e.,Pascal VOC and MS-COCO).Our experimental results show that our method outperforms state-of-the-art methods.LYU Fan LI Linyan Victor S.Sheng FU Qiming HU Fuyuan 2019Chinese Journal of Electronics2019,28,6:3
17Synthesis of Single-Crystalline Anatase TiO_2 Nanorods With High-Performance Dye-Sensitized Solar Cells显示文摘Single-crystalline anatase TiO_2 nanorods have been prepared by solvothermal method using tetrabutylammonium hydroxide(TBAH) as a morphology controlling agent.The obtained TiO_2 nanorods are dominated by a large percentage of {010} facets.The power conversion efficiency of dye-sensitized solar cell(DSSC) based on anatase TiO_2 nanorods(8.66%) exhibits a significant improvement(35%) compared to that of P25 TiO_2(5.66%).The high performance of the anatase TiO_2 nanorods solar cell is ascribed to their large percent of exposed {010} facets as well as balancing their surface areas and sizes.Jin Liu Jun Luo Weiguang Yang Yali Wang Linyan Zhu Yueyang Xu Ying Tang Yajing Hu Chen Wang Yigang Chen Weimin Shi 2015Journal of Materials Science & Technology2015,31,1:2
18Wind power time series simulation model based on typical daily output processes and Markov algorithm显示文摘The simulation of wind power time series is a key process in renewable power allocation planning,operation mode calculation,and safety assessment.Traditional single-point modeling methods discretely generate wind power at each moment;however,they ignore the daily output characteristics and are unable to consider both modeling accuracy and efficiency.To resolve this problem,a wind power time series simulation model based on typical daily output processes and Markov algorithm is proposed.First,a typical daily output process classification method based on time series similarity and modified K-means clustering algorithm is presented.Second,considering the typical daily output processes as status variables,a wind power time series simulation model based on Markov algorithm is constructed.Finally,a case is analyzed based on the measured data of a wind farm in China.The proposed model is then compared with traditional methods to verify its effectiveness and applicability.The comparison results indicate that the statistical characteristics,probability distributions,and autocorrelation characteristics of the wind power time series generated by the proposed model are better than those of the traditional methods.Moreover,modeling efficiency considerably improves.Zhihui Cong Yuecong Yu Linyan Li Jie Yan 2022Global Energy Interconnection2022,5,1:2
19Hydrocarbon migration in fracture-cave systems of carbonate reservoirs under tectonic stresses:A modeling study显示文摘The Tahe oilfield,located in the southwest of the Akekule nosing structure,northern Tarim basin,was the most prolific oilfield targeting at the Ordovician carbonate reservoirs in China.The reservoir space was dominant with fracture-cave systems commonly induced by tectonics and karstification.Although hydrocarbon production had proceeded for two decades in the Tahe oilfiled,the control of oil and gas accumulations was still doubtful.In this work,the periodic fluid flow induced by cyclic tectonic stresses was proposed as the mechanism of hydrocarbon migration in the fracture-cave systems of carbonate reservoirs.The fracture networks formed conduits for fluid flow,and the fluid pressure in caves transmitted from stress field provided the driving force.The constitutive equations were established among stresses,fracture densities and flow velocities.Four quasi-3D geological models were constructed to simulate the flow velocities on the Ordovician surface of Akekule nosing structure in the critical tectonic stages.The simulated results supplied indicative information on oil and gas migration and accumulation in the tectonic stages.Combining with the oil and gas charge history,a conceptual model was built to reveal the multi-stage oil and gas charge and accumulation in the Ordovician of Akekule nosing structure.Chenjun Huang Geyun Liu Yongsheng Ma Xingui Zhou Linyan Zhang Jinyin Yin Jinrui Guo 2019Petroleum Research2019,4,4:2
