2Combining LPJ-GUESS and HASM to simulate the spatial distribution of forest vegetation carbon stock in China显示文摘它在因为他们在陆上的生态系统的碳股票拥有大率,精确地在地区性的规模估计森林碳股票和空间分发是很重要的。然而,在地区性的规模的森林碳存货的当前的评价主要取决于森林库存数据,并且整个过程消费太多劳动,钱和时间。并且同时,它在森林碳存储上有许多否定影响更新。以便弄明白这些问题,基于当模特儿的高精确性表面(HASM ) ,这份报纸建议一个森林植被碳存储模拟方法。这个新方法作为 HASM 的起始的值采用 LPJ 猜测模型的输出并且把库存数据用作 HASM 的样品点在中国模仿森林碳存储的分发。这研究也作为数据来源采用中国的第七森林资源统计产生样品点,并且它也作为模拟精确性测试工作。HASM 模拟证明中国的全部的森林碳存储是 9.2405 Pg,当计算价值基于森林资源统计是 7.8115 Pg 时。森林资源统计基于森林华盖闭合被拿,并且 HASM 的结果对真实森林碳存储更合适。模拟结果也显示西南的山区域和东北森林是在中国的重要森林碳水库,并且他们分别地说明 39.82% 国家和 20.46% 总数森林植被碳存货。与以前的价值(1975-1995 ) 相比,二个区域的碳存储确实清楚地增加,这表明。这研究的结果证明在在中国的最后十年的大规模重新造林达到一个重要的碳水池。ZHAO Mingwei YUE Tianxiang ZHAO Na SUN Xiaofang ZHANG Xingying 2014Journal of Geographical Sciences2014,24,2:18
3Sensitivity studies of a high accuracy surface modeling method显示文摘The sensitivities of the initial value and the sampling information to the accuracy of a high accuracy surface modeling(HASM) are investigated and the implementations of this new modeling method are modified and enhanced. Based on the fundamental theorem of surface theory, HASM is developed to correct the error produced in geographical information system and ecological modeling process. However, the earlier version of HASM is theoretically incomplete and its initial value must be produced by other surface modeling methods, such as spline, which limit its promotion. In other words, we must use other interpolators to drive HASM. According to the fundamental theorem of surface theory, we modify HASM, namely HASM.MOD, by adding another important nonlinear equation to make it independent of other methods and, at the same time, have a complete and solid theory foundation. Two mathematic surfaces and monthly mean temperature of 1951–2010 are used to validate the effectiveness of the new method. Experiments show that the modified version of HASM is insensitive to the selection of initial value which is particular important for HASM. We analyze the sensitivities of sampling error and sampling ratio to the simulation accuracy of HASM.MOD. It is found that sampling information plays an important role in the simulation accuracy of HASM.MOD. Another feature of the modified version of HASM is that it is theoretically perfect as it considers the third equation of the surface theory which reflects the local warping of the surface. The modified HASM may be useful with a wide range of spatial interpolation as it would no longer rely on other interpolation methods.ZHAO Na YUE TianXiang ZHAO MingWei DU ZhengPing FAN ZeMeng CHEN ChuanFa 2014Science China Earth Sciences2014,57,10:9
4Hydroisomerization performance of platinum supported on ZSM-22/ZSM-23 intergrowth zeolite catalyst显示文摘Hydroisomerization catalysts Pt/ZSM-22,Pt/ZSM-23,and Pt/ZSM-22/ZSM-23 were prepared by supporting Pt on ZSM-22,ZSM-23,and intergrowth zeolite ZSM-22/ZSM-23,respectively.The typical physicochemical properties of these catalysts were characterized by X-Ray Diffraction(XRD),N2 absorption-desorption,Pyridine-Fourier Transform Infrared(Py-FTIR),Transmission Electron Microscopy(TEM),X-Ray Fluorescence(XRF),Scanning Electron Microscopy(SEM) and NH3-Temperature Programmed Desorption(NH3-TPD),and the performance of these catalysts in n-dodecane hydroisomerization was evaluated in a continuous down-flow fixed bed with a stainless steel tubular reactor.The characterization results indicated that the intergrowth zeolite ZSM-22/ZSM-23 possessed the dual structure of ZSM-22 and ZSM-23,and the catalyst Pt/ZSM-22/ZSM-23 had similar pores and weak acidity to Pt/ZSM-22 and Pt/ZSM-23 catalysts.Moreover,Pt/ZSM-22/ZSM-23 catalyst showed a high selectivity in hydroisomerization of long chain n-alkanes to mono-branched isomers.The evaluation results for n-dodecane hydroisomerization indicated that the activity of Pt/ZSM-22/ZSM-23 was the lowest,while the hydroisomerization selectivity was the highest among the three catalysts.The maximum yield of i-dodecane product was 68.3% over Pt/ZSM-22/ZSM-23 at 320 oC.Chi Kebin Zhao Zhen Tian Zhijian Hu Sheng Yan Lijun Li Tianshu Wang Bingchun Meng Xiangbin Gao Shanbin Tan Mingwei Liu Yanfeng 2013Petroleum Science2013,10,2:8
5A fundamental theorem for eco-environmental surface modelling and its applications显示文摘We propose a fundamental theorem for eco-environmental surface modelling(FTEEM) in order to apply it into the fields of ecology and environmental science more easily after the fundamental theorem for Earth’s surface system modeling(FTESM). The Beijing-Tianjin-Hebei(BTH) region is taken as a case area to conduct empirical studies of algorithms for spatial upscaling, spatial downscaling, spatial interpolation, data fusion and model-data assimilation, which are based on high accuracy surface modelling(HASM), corresponding with corollaries of FTEEM. The case studies demonstrate how eco-environmental surface modelling is substantially improved when both extrinsic and intrinsic information are used along with an appropriate method of HASM. Compared with classic algorithms, the HASM-based algorithm for spatial upscaling reduced the root-meansquare error of the BTH elevation surface by 9 m. The HASM-based algorithm for spatial downscaling reduced the relative error of future scenarios of annual mean temperature by 16%. The HASM-based algorithm for spatial interpolation reduced the relative error of change trend of annual mean precipitation by 0.2%. The HASM-based algorithm for data fusion reduced the relative error of change trend of annual mean temperature by 70%. The HASM-based algorithm for model-data assimilation reduced the relative error of carbon stocks by 40%. We propose five theoretical challenges and three application problems of HASM that need to be addressed to improve FTEEM.Tianxiang YUE Na ZHAO Yu LIU Yifu WANG Bin ZHANG Zhengping DU Zemeng FAN Wenjiao SHI Chuanfa CHEN Mingwei ZHAO Dunjiang SONG Shihai WANG Yinjun SONG Changqing YAN Qiquan LI Xiaofang SUN Lili ZHANG Yongzhong TIAN Wei WANG Ying’an WANG Shengnan MA Hongsheng HUANG Yimin LU Qing WANG Chenliang WANG Yuzhu WANG Ming LU Wei ZHOU Yi LIU Xiaozhe YIN Zong WANG Zhengyi BAO Miaomiao ZHAO Yapeng ZHAO Yimeng JIAO Ufra NASEER Bin FAN Saibo LI Yang YANG John PWILSON 2020Science China Earth Sciences2020,63,8:7
6Parameter Group Optimization by Combining CUBE with Surface Filtering and Its Application显示文摘Shallow water multi-beam echo sounders(MBESs)are characterized by their high resolution and high density,and MBES data processing is a hotspot in modern marine surveying.The Combined Uncertainty and Bathymetry Estimator(CUBE)is the mainstream MBES data processing algorithm,although little is known about its core theories and parameters.In this paper,the basic principle,mathematical model,key parameters,and main processing steps of CUBE are described systematically.A parameter group optimization method that combines CUBE with a surface filter is established.Additionally,an example is given that shows the steps for parameter group optimization,including selection of a typical area,parameter group testing,and comparative analysis,and the method is then applied to shallow water MBES data processing.The results show that the method can improve the accuracy and efficiency of automatic data processing effectively,and it is thus of engineering application value.Dineng ZHAO Ziyin WU Jieqiong ZHOU Mingwei WANG Zhihao LIU Jiabiao LI 2020Journal of Geodesy and Geoinformation Science2020,3,2:7
7Germination inhibitors detected in Sapium sebiferum seeds显示文摘This study identifies endogenous inhibitors of germination associated with seed dormancy in Sapium sebiferum,Chinese tallow.Seed extracts were separated into five distinct fractions(petroleum ether,ether,ethyl acetate,methanol,and aqueous)and tested for their effect on germination of cabbage seeds.There were no significant differences in germination percentages and germination index(GI)between the solvents and the control.The five fractions differentially reduced germination percentage and GI values of cabbage seeds.According to the GI results,the greatest inhibition was with the ether fraction followed by methanol,ethyl acetate,petroleum ether,and aqueous fractions.Gas chromatography–mass spectrometry identified the constituents of the four organic fractions.Compared with the mass spectrum of the National Institute of Standards and Technology library,a compound was confirmed,provided it was more than 85%similar.Analysis of ether extracts identified four compounds:butylated hydroxytoluene(BHT;19.7%),1,2-benzenediol(4.1%),phydroxycinnamic acid,ethyl ester(2.8%),and n-hexadecanoic acid(1.4%).Fourteen,20,and 9 compounds were identified in methanol,ethyl acetate,and petroleum ether extracts,respectively.The IC50 of BHT(the concentration at which BHT inhibits radicle growth by 50%)was 54.8 mg/L,indicating that the presence of BHT might be the primary cause of dormancy in S.sebiferum seeds.Tingting Zhao Cunmeng Qian Yunpeng Gao Li Chen Mingwei Zhu Yueting Pan Shuxian Li 2019Journal of Forestry Research2019,30,6:4
8A machine learning-based algorithm used to estimate the physiological elongation of ocular axial length in myopic children显示文摘Background:Axial myopia is the most common type of myopia.However,due to the high incidence of myopia in Chinese children,few studies estimating the physiological elongation of the ocular axial length(AL),which does not cause myopia progression and differs from the non-physiological elongation of AL,have been conducted.The purpose of our study was to construct a machine learning(ML)-based model for estimating the physiological elongation of AL in a sample of Chinese school-aged myopic children.Methods:In total,1011 myopic children aged 6 to 18 years participated in this study.Cross-sectional datasets were used to optimize the ML algorithms.The input variables included age,sex,central corneal thickness(CCT),spherical equivalent refractive error(SER),mean K reading(K-mean),and white-to-white corneal diameter(WTW).The output variable was AL.A 5-fold cross-validation scheme was used to randomly divide all data into 5 groups,including 4 groups used as training data and one group used as validation data.Six types of ML algorithms were implemented in our models.The best-performing algorithm was applied to predict AL,and estimates of the physiological elongation of AL were obtained as the partial derivatives of AL_(predicted)-age curves based on an unchanged SER value with increasing age.Results:Among the six algorithms,the robust linear regression model was the best model for predicting AL,with a R^(2) value of 0.87 and relatively minimal averaged errors between the predicted AL and true AL.Based on the partial derivatives of the AL_(predicted)-age curves,the estimated physiological AL elongation varied from 0.010 to 0.116 mm/year in male subjects and 0.003 to 0.110 mm/year in female subjects and was influenced by age,SER and K-mean.According to the model,the physiological elongation of AL linearly decreased with increasing age and was negatively correlated with the SER and the K-mean.Conclusions:The physiological elongation of the AL is rarely recorded in clinical data in China.In cases of unavailable clinical dat,an ML algorithm could provide practitioners a reasonable model that can be used to estimate the physiological elongation of AL,which is espedally useful when monitoring myopia progression in orthokeratology lens wearers.Tao Tang Zekuan Yu Qiong Xu Zisu Peng Yuzhuo Fan Kai Wang Qiushi Ren Jia Qu Mingwei Zhao 2020Eye and Vision2020,7,1:4
9Recent Progress on Al_(2)O_(3)-C Refractories with Low/ultra-low Carbon Content:A Review显示文摘This work intends to provide a comprehensive review on the development of Al_(2)O_(3)-C refractories with low/ultra-low carbon content.It covers three parts:carbon materials,microstructure optimization of the refractory matrix by ceramic phases,and application of metal Al as raw material.Carbon black,expanded graphite,and ultrafine microcrystalline graphite,as price-competitive carbon materials,can be chosen to prepare the low-carbon Al_(2)O_(3)-C refractories after some special treatment.Ni/Co/Fe-catalyzed phenolic resin contributes to improving the properties of the low-carbon Al_(2)O_(3)-C refractories.The performance deterioration of the low-carbon Al_(2)O_(3)-C refractories can also be improved by in-situ formed or pre-synthesized ceramic phases.Metal Al,characterized by plasticity forming,acceleration of sintering,oxidation resistance,and high reactivity,can be used as raw materials to completely replace graphite,and the prepared resin bonded Al-Al_(2)O_(3)based refractories are one novel development direction of the ultra-low carbon Al_(2)O_(3)-C refractories.ZHAO Chenrui YAN Mingwei LI Hongyu NIU Zhiwang LIANG Baoqing SHANG Junli 2022China's Refractories2022,31,1:4
10Proteomics provides individualized options of precision medicine for patients with gastric cancer显示文摘While precision medicine driven by genome sequencing has revolutionized cancer care,such as lung cancer,its impact on gastric cancer(GC)has been minimal.GC patients are routinely treated with chemotherapy,but only a fraction of them receive the clinical benefit.There is an urgent need to develop biomarkers or algorithms to select chemo-sensitive patients or apply targeted therapy.Here,we carried out retrospective analyses of 1,020 formalin-fixed,paraffin-embedded GC surgical resection samples from 5 hospitals and developed a mass spectrometry-based workflow for proteomic subtyping of GC.We identified two proteomic subtypes:the chemo-sensitive group(CSG)and the chemo-insensitive group(CIG)in the discovery set.The 5-year overall survival of CSG was significantly improved in patients who had received adjuvant chemotherapy after surgery compared with those who received surgery only(64.2%vs.49.6%;Cox P-value=0.002),whereas no such improvement was observed in CIG(50.0%vs.58.6%;Cox P-value=0.495).We validated these results in an independent validation set.Further,differential proteome analysis uncovered 9 FDA-approved drugs that may be applicable for targeted therapy of GC.A prospective study is warranted to test these findings for future GC patient care.Wenwen Huang Dongdong Zhan Yazhuo Li Nairen Zheng Xin Wei Bin Bai Kecheng Zhang Mingwei Liu Xuefei Zhao Xiaotian Ni Xia Xia Jinwen Shi Cheng Zhang Zhihao Lu Jiafu Ji Juan Wang Shiqi Wang Gang Ji Jipeng Li Yongzhan Nie Wenquan Liang Xiaosong Wu Jianxin Cui Yongsheng Meng Feilin Cao Tieliu Shi Weimin Zhu Yi Wang Lin Chen Qingchuan Zhao Hongwei Wang Lin Shen Jun Qin 2021Science China(Life Sciences)2021,64,8:3
11Space- and ground-based CO_2 measurements: A review显示文摘The climate warming is mainly due to the increase in concentrations of anthropogenic greenhouse gases, of which CO_2 is the most important one responsible for radiative forcing of the climate. In order to reduce the great estimation uncertainty of atmospheric CO_2 concentrations, several CO_2-related satellites have been successfully launched and many future greenhouse gas monitoring missions are planned. In this paper, we review the development of CO_2 retrieval algorithms, spatial interpolation methods and ground observations. The main findings include: 1) current CO_2 retrieval algorithms only partially account for atmospheric scattering effects; 2) the accurate estimation of the vertical profile of greenhouse gas concentrations is a long-term challenge for remote sensing techniques; 3) ground-based observations are too sparse to accurately infer CO_2 concentrations on regional scales; and 4) accuracy is the primary challenge of satellite estimation of CO_2 concentrations. These findings, taken as a whole, point to the need to develop a high accuracy method for simulation of carbon sources and sinks on the basis of the fundamental theorem of Earth's surface modelling, which is able to efficiently fuse space- and ground-based measurements on the one hand and work with atmospheric transport models on the other hand.YUE TianXiang ZHANG LiLi ZHAO MingWei WANG YiFu John WILSON 2016Science China Earth Sciences2016,59,11:2
12A high-accuracy method for simulating the XCO_2 global distribution using GOSAT retrieval data显示文摘A high-accuracy surface modeling(HASM)method based on the fundamental theorem of surfaces,is developed to simulate XCO_2 surfaces using the GOSAT retrieval XCO_2 data.Two tests are designed to investigate the simulation accuracy.The first test divides the existing satellite retrieval XCO2 data into training points and testing points,and simulates the XCO2 surface using the training points while computing the simulation error using the testing points.The absolute mean error(MAE)of the testing points is 1.189 ppmv,and the corresponding values of the comparison methods,Ordinary Kriging,IDW,and Spline are1.203,1.301,and 1.355 ppmv,respectively.The second test simulates the XCO_2 surface using all the satellite retrieval points and uses the TCCON(Total Carbon Column Observing Network)site observation values as the ture values.For the six typical TCCON sites,the HASM simulation MAE is 1.688 ppmv,and the satellite retrieval MAE at the same sites is 2.147 ppmv.These results indicate that HASM can successfully simulate XCO_2 surfaces based on satellite retrieval data.ZHAO MingWei ZHANG XingYing YUE TianXiang WANG Chun JIANG Ling SUN JingLu 2017Science China Earth Sciences2017,60,1:2
13On the topographic entity-oriented digital elevation model construction method for urban area land surface显示文摘Human activity transforms a land surface into a complex surface where artificial and natural landforms coexist and continuous and emergent landforms merge.In this background,the problems of conventional digital elevation models(DEMs),such as morphological distortion,complicated updates,and lack of information,are increasingly prominent.This study proposes a new idea of DEM construction based on the concept of geographic ontology.First,landforms with common features are abstracted into a certain type of topographic entity based on their morphologies and semantics.For each type of topographic entity,a DEM was constructed independently based on the available elevation information and other information about the semantics and spatial relationships.Second,individual DEMs were merged into a complete DEM following certain rules.A 1 km2 area located in the suburb of Nanjing,Jiangsu Province,China,was selected as the experimental area.The effectiveness of the model construction method proposed in this study was verified.The results show that the DEM constructed according to the idea of this study has a significantly better performance than the conventional DEMs.The constructed DEM in this study can well represent ground objects,such as slopes,farmland,and ditches.In particular,the constructed DEM ensures the morphological accuracy of the ground objects.Mingwei ZHAO Ling JIANG Chun WANG Cancan YANG Xin YANG 2021Frontiers of Earth Science2021,15,3:2

16The critical role of m^(6)A methylation in the pathogenesis of Graves'ophthalmopathy显示文摘Purpose:To investigate the role of N6-methyladenosine(m^(6)A)RNA modification in the pathogenesis of Graves'ophthalmopathy(GO).Methods:Surgically excised extraocular muscles from 7 patients with GO and 5 subjects without GO were used.The global m^(6)A levels in the specimens were determined using an m^(6)A RNA methylation quantification kit.RNA sequencing(RNA-seq)was used to analyze the molecules involved in the regulation of m^(6)A RNA methylation and the differential expression of mRNAs between the two groups(4 eyes,respectively).The expression of m^(6)A RNA modification genes was evaluated by real-time PCR.The functional implications of the gene alterations between the GO and control specimens were determined by Gene Ontology analysis.Results:The m^(6)A level was significantly increased in the specimens of GO patients compared to the control specimens(P<0.05).The expression of m^(6)A methylation regulators,such as WT1 associated protein(WTAP),alkylation repair homolog protein 5(ALKBH5),E74 like ETS transcription factor 3(ELF3),YTH N6-methyladenosine RNA binding protein 2(YTHDF2),YTHDF3 and YTH domain containing 2(YTHDC2),was significantly upregulated(P<0.05).Gene Ontology enrichment analysis showed that the most highly upregulated genes and biological pathways were related to the immune response and inflammatory processes such as lymphocyte activation,leukocyte differentiation,cytokine production and cytokine-mediated signaling pathways.Conclusions:Our results suggest that m^(6)A methylation may play a critical role in the pathogenesis of GO and that targeting genes that regulate m^(6)A methylation may provide a new therapeutic approach for GO.Li Zhu Siyan Li Shikun He Qizhe Tong Lejin Wang Xiaohua Li Xi Wu Qingyu Meng Enzhong Jin Chuan Zhang Tianyuan Li Ningda Xu Lvzhen Huang Yi Wang Mingwei Zhao 2020Eye and Vision2020,7,1:1
