| 1 | Altered trends in carbon uptake in China’s terrestrial ecosystems under the enhanced summer monsoon and warming hiatus显示文摘The carbon budgets in terrestrial ecosystems in China are strongly coupled with climate changes.Over the past decade,China has experienced dramatic climate changes characterized by enhanced summer monsoon and decelerated warming.However,the changes in the trends of terrestrial net ecosystem production(NEP)in China under climate changes are not well documented.Here,we used three ecosystem models to simulate the spatiotemporal variations in China's NEP during 1982–2010 and quantify the contribution of the strengthened summer monsoon and warming hiatus to the NEP variations in four distinct climatic regions of the country.Our results revealed a decadal-scale shift in NEP from a downtrend of–5.95 Tg C/yr^2(reduced sink)during 1982–2000 to an uptrend of 14.22 Tg C/yr^2(enhanced sink)during 2000–10.This shift was essentially induced by the strengthened summer monsoon,which stimulated carbon uptake,and the warming hiatus,which lessened the decrease in the NEP trend.Compared to the contribution of 56.3%by the climate effect,atmospheric CO2 concentration and nitrogen deposition had relatively small contributions(8.6 and 11.3%,respectively)to the shift.In conclusion,within the context of the global-warming hiatus,the strengthening of the summer monsoon is a critical climate factor that enhances carbon uptake in China due to the asymmetric response of photosynthesis and respiration.Our study not only revealed the shift in ecosystem carbon sequestration in China in recent decades,but also provides some insight for understanding ecosystem carbon dynamics in other monsoonal areas. | Honglin He Shaoqiang Wang Li Zhang Junbang Wang Xiaoli Ren Lei Zhou Shilong Piao Hao Yan Weimin Ju Fengxue Gu Shiyong Yu Yuanhe Yang Miaomiao Wang Zhongen Niu Rcmg Ge Huimin Yan Mei Huang Guoyi Zhou Yongfei Bai Zongqiang Xie Zhiyao Tang Bingfang Wu Leiming Zhang Nianpeng He Qiufeng Wang Guirui Yu | 2019 | National Science Review2019，6，3： | 24 |
| 2 | GPS short-delay multipath estimation and mitigation based on least square method显示文摘The GPS multipath signal model is presented,which indicates that the coherent DLL outputs in multipath environment are the convolution between the ideal DLL outputs and the channel responses.So the channel responses can be estimated by a least square method using the observed curve of the DLL discriminator.In terms of the estimated multipath channels,two multipath mitigation methods are discussed,which are equalization filtering and multipath subtracting,respectively.It is shown,by computer simulation,that the least square method has a good performance in channels estimation and the multipath errors can be mitigated almost completely by either of the methods.However,the multipath subtracting method has relative small remnant errors than equalization filtering. | Zhang Shengkang~(1,2),Wang Hongbo~(1,2),Yang Jun~(1,2) & He Leiming~(1,2) 1.Beijing Inst.of Radio Metrology and Measurement,Beijing 100854,P.R.China 2.National Key Laboratory of Metrology and Calibration Technology,Beijing 100854,P.R.China | 2009 | Journal of Systems Engineering and Electronics2009，20，5： | 6 |
| 3 | Expression of Wnt and NCX1 and its correlation with cardiomyocyte apoptosis in mouse with myocardial hypertrophy显示文摘Objective:To study the correlation between expression of Wnt and NCXl and cardiomyocyte apoptosis in mouse with myocardial hypertrophy.Methods:C57B/16 male mice were given the subcutaneous injection of 1 mg/kg isoprenaline to build the myocardial hypertrophy model.After 14 d of model building,mice were executed by cervical vertebra luxation.The ratio of heart weight/body weight(HW/BW) and heart weight/tibia length(HW/TL) was observed and proved using HE staining mat detected the size of eaidiomyocytes.40 male C57B/16 mice were randomly divided into the sham group(normal saline) and model group(isoprenaline),with 20 mice in each group.The terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling was applied to detect the cardiomyocyte apoptosis;while Western blot and immunohistochemistry were employed to detect the expression of Wnt and NCX1.Meanwhile,the correlation between these two proteins and cardiomyocyte apoptosis was explored.Results:Compared with the sham group,the ratio of HW/BW and HW/TL was increased in the model group,as well as the bigger and hypertrophied cardiomyocytes,decreased number and increased apoptosis of eaidiomyocytes,and increased positive expression of Wnt3 a,WntSa and NCXl in the cardiac muscle tissue.Besides,there was positive correlation between the expression of Wnt and NCXl and the cardiomyocyte apoptosis.Conclusions:The expression of Wnt3 a,Wnt5a and NCXl in mouse with myocardial hypertrophy is increased and positively correlated with the cardiomyocyte apoptosis. | Jing He Yi Cai Leiming Luo Rong Wang | 2015 | Asian Pacific Journal of Tropical Medicine2015，8，11： | 5 |
| 4 | Regorafenib-loaded poly(lactide-co-glycolide) microspheres designed to improve transarterial chemoembolization therapy for hepatocellular carcinoma显示文摘Transarterial chemoembolization(TACE)has been widely introduced to treat hepatocellular carcinoma(HCC)especially for unresectable patients for decades.However,TACE evokes an angiogenic response due to the secretion of vascular endothelial growth factor(VEGF),resulting in the formation of new blood vessels and eventually tumor recurrence.Thus,we aimed to develop regorafenib(REGO)-loaded poly(lactide-co-glycolide)(PLGA)microspheres that enabled localized and sustained drug delivery to limit proangiogenic responses following TACE in HCC treatment.REGO-loaded PLGA microspheres were prepared using the emulsion-solvent evaporation/extraction method,in which DMF was selected as an organic phase co-solvent.Accordingly,we optimized the proportion of DMF,which the optimal ratio to DCM was 1:9(v/v).After preparation,the microspheres provided high drug loading capacity of 28.6%,high loading efficiency of 91.5%,and the average particle size of 149μm for TACE.IR spectra and XRD were applied to confirming sufficient REGO entrapment.The in vitro release profiles demonstrated sustained drug release of microspheres for more than 30 d To confirm the role of REGO-loaded microspheres in TACE,the cell cytotoxic activity on HepG2 cells and anti-angiogenic effects in HUVECs Tube-formation assay were studied in combination with miriplatin.Moreover,the microspheres indicated the potential of antagonizing miriplatin resistance of HepG2 cells in vitro.Pharmacokinetics preliminary studies exhibited that REGO could be sustainably released from microspheres for more than 30d after TACE in vivo.In vivo anti-tumor efficacy was further determined in HepG2 xenograft tumor mouse model,demonstrating that REGO microspheres could improve the antitumor efficacy of miriplatin remarkably compared with miriplatin monotherapy.In conclusion,the obtained REGO microspheres demonstrated promising therapeutic effects against HCC when combined with TACE. | Xiang Li Guangwei He Feng Su Zhaoxing Chu Leiming Xu Yazhong Zhang Jianping Zhou Yang Ding | 2020 | Asian Journal of Pharmaceutical Sciences2020，15，6： | 4 |
| 5 | An Early Paleozoic Tectonic Mélange at the Western Margin of West Cathaysia: Constraints from Organic-walled Microfossils显示文摘The Jiangshan-Shaoxing-Pingxiang Fault(JSP Fault) is traditionally considered as the boundary between the Yangtze and Cathaysia blocks in South China. Whether the previously defined Shenshan and Kuli formations located along the JSP fault and near the Xinyu City, Jiangxi Province, are continuous strata or parts of a tectonic mélange is important for understanding the geological history of South China. A carbonaceous phyllite from the area, previously considered as part of the Neoproterozoic Shenshan and Kuli formations, is analyzed palynologically in this study. The AsteridiumComasphaeridium acritarch assemblage found in the slate can be correlated with the basal Cambrian AsteridiumHeliosphaeridium-Comasphaeridium(AHC) acritarch assemblage in Tarim and the Yangtze Block. The early Cambrian biostratigraphical age assignment for the carbonaceous phyllite indicates the presence of both Neoproterozoic and Cambrian rocks in the sedimentary package, and supports that the package is a part of tectonic mélange rather than a continuous Neoproterozoic strata. The Cambrian slate is the youngest known lithology in the mélange at present. | WANG Lijun ZHANG Kexin HE Weihong YIN Leiming Shoufa LIN | 2020 | Acta Geologica Sinica(English Edition)2020，94，4： | 2 |
| 6 | Multi-Label Chinese Comments Categorization: Comparison of Multi-Label Learning Algorithms显示文摘Multi-label text categorization refers to the problem of categorizing text througha multi-label learning algorithm. Text classification for Asian languages such as Chinese isdifferent from work for other languages such as English which use spaces to separate words.Before classifying text, it is necessary to perform a word segmentation operation to converta continuous language into a list of separate words and then convert it into a vector of acertain dimension. Generally, multi-label learning algorithms can be divided into twocategories, problem transformation methods and adapted algorithms. This work will usecustomer's comments about some hotels as a training data set, which contains labels for allaspects of the hotel evaluation, aiming to analyze and compare the performance of variousmulti-label learning algorithms on Chinese text classification. The experiment involves threebasic methods of problem transformation methods: Support Vector Machine, Random Forest,k-Nearest-Neighbor;and one adapted algorithm of Convolutional Neural Network. Theexperimental results show that the Support Vector Machine has better performance. | Jiahui He Chaozhi Wang Hongyu Wu Leiming Yan Christian Lu | 2019 | Journal of New Media2019，1，2： | 2 |

| 11 | A database of modeled gridded dry deposition velocities for 45 gaseous species and three particle size ranges across North America显示文摘The dry deposition process refers to the flux loss of an atmospheric pollutant due to uptake of the pollutant by the earth’s surfaces.Dry deposition flux of a chemical species is typically calculated as the product of its surface-layer concentration and its dry deposition velocity(V_(d)).Field measurement based V_(d) data are very scarce or do not exist for many chemical species considered in chemistry transport models.In the present study,gaseous and particulate dry deposition schemes were applied to generate a database of hourly V_(d) for 45 gaseous species and three particle size ranges for two years(2016–2017)at a 15 kmby 15 km horizontal resolution across North America.Hourly V_(d) of the 45 gaseous species ranged from<0.001 to 4.6 cm/sec across the whole domain,with chemical species-dependentmedian(mean)values being in the range of 0.018–1.37 cm/sec(0.05–1.43 cm/sec).The spatial distributions of the two-year average V_(d) showed values higher than 1–3 cm/sec for those soluble and reactive species over certain land types.Soluble species have the highest V_(d) over water surfaces,while insoluble but reactive species have the highest V_(d) over forests.Hourly V_(d) of PM_(2.5) across the whole domain ranged from 0.039 to 0.75 cm/sec with median(mean)value of 0.18(0.20)cm s^(−1),while the mean V_(d) for PM_(2.5)–10 is twice that of PM_(2.5).Uncertainties in the modeled V_(d) are typically on the order of a factor of 2.0 or larger,which needs to be considered when applying the dataset in other studies. | Leiming Zhang Zhuanshi He Zhiyong Wu Anne Marie Macdonald Jeffrey R.Brook Shailesh Kharol | 2023 | Journal of Environmental Sciences2023，，5： | 0 |
| 12 | Semi-asynchronous personalized federated learning for short-term photovoltaic power forecasting显示文摘Accurate forecasting for photovoltaic power generation is one of the key enablers for the integration of solar photovoltaic systems into power grids.Existing deep-learning-based methods can perform well if there are sufficient training data and enough computational resources.However,there are challenges in building models through centralized shared data due to data privacy concerns and industry competition.Federated learning is a new distributed machine learning approach which enables training models across edge devices while data reside locally.In this paper,we propose an efficient semi-asynchronous federated learning framework for short-term solar power forecasting and evaluate the framework performance using a CNN-LSTM model.We design a personalization technique and a semi-asynchronous aggregation strategy to improve the efficiency of the proposed federated forecasting approach.Thorough evaluations using a real-world dataset demonstrate that the federated models can achieve significantly higher forecasting performance than fully local models while protecting data privacy,and the proposed semi-asynchronous aggregation and the personalization technique can make the forecasting framework more robust in real-world scenarios. | Weishan Zhang Xiao Chen Ke He Leiming Chen Liang Xu Xiao Wang Su Yang | 2023 | Digital Communications and Networks2023，9，5： | 0 |

| 14 | Pressure-induced disordering of site occupation in iron–nickel nitrides显示文摘Controlled disordering of substitutional and interstitial site occupation at high pressure can lead to important changes in the structural and physical properties of iron–nickel nitrides.Despite important progress that has been achieved,structural characterization of ternary Fe–Ni–N compounds remains an open problem owing to the considerable technical challenges faced by current synthetic and structural approaches for fabrication of bulk ternary nitrides.Here,iron–nickel nitride samples are synthesized as spherical-like bulk materials through a novel highpressure solid-state metathesis reaction.By employing a wide array of techniques,namely,neutron powder diffraction,Rietveld refinement methods combined with synchrotron radiation angle-dispersive x-ray diffraction,scanning electron microscopy/energy dispersive x-ray spectroscopy,and transmission electron microscopy,we demonstrate that high-temperature and high-pressure confinement conditions favor substitutional and interstitial site disordering in ternary iron–nickel nitrides.In addition,the effects of interstitial nitrogen atoms and disorderly substituted nickel atoms on the elastic properties of the materials are discussed. | Binbin Wu Li Lei Feng Zhang Qiqi Tang Shan Liu Meifang Pu Duanwei He Yuanhua Xia Leiming Fang Hiroaki Ohfuji Tetsuo Irifune | 2021 | Matter and Radiation at Extremes2021，6，3： | 0 |
