| 5 | Global characterization and monitoring of forest cover using Landsat data: opportunities and challenges显示文摘The compilation of global Landsat data-sets and the ever-lowering costs of computing now make it feasible to monitor the Earth’s land cover at Landsat resolutions of 30 m.In this article,we describe the methods to create global products of forest cover and cover change at Landsat resolutions.Nevertheless,there are many challenges in ensuring the creation of high-quality products.And we propose various ways in which the challenges can be overcome.Among the challenges are the need for atmospheric correction,incorrect calibration coefficients in some of the data-sets,the different phenologies between compila-tions,the need for terrain correction,the lack of consistent reference data for training and accuracy assessment,and the need for highly automated character-ization and change detection.We propose and evaluate the creation and use of surface reflectance products,improved selection of scenes to reduce phenological differences,terrain illumination correction,automated training selection,and the use of information extraction procedures robust to errors in training data along with several other issues.At several stages we use Moderate Resolution Spectro-radiometer data and products to assist our analysis.A global working prototype product of forest cover and forest cover change is included. | John R.Townshend Jeffrey G.Masek Chengquan Huang Eric.F.Vermote Feng Gao Saurabh Channan Joseph O.Sexton Min Feng Raghuram Narasimhan Dohyung Kim Kuan Song Danxia Song Xiao-Peng Song Praveen Noojipady Bin Tan Matthew C.Hansen Mengxue Li Robert E.Wolfe | 2012 | International Journal of Digital Earth2012，5，5： | 10 |
| 6 | Removal of formaldehyde over Mn_xCe_(1- x)O_2 catalysts: Thermal catalytic oxidation versus ozone catalytic oxidation显示文摘MnxCe1-xO2(x:0.3–0.9)prepared by Pechini method was used as a catalyst for the thermal catalytic oxidation of formaldehyde(HCHO).At x=0.3 and 0.5,most of the manganese was incorporated in the fluorite structure of Ce O2to form a solid solution.The catalytic activity was best at x=0.5,at which the temperature of 100%removal rate is the lowest(270°C).The temperature for 100%removal of HCHO oxidation is reduced by approximately 40°C by loading 5 wt.%Cu Oxinto Mn0.5Ce0.5O2.With ozone catalytic oxidation,HCHO(61 ppm)in gas stream was completely oxidized by adding 506 ppm O3over Mn0.5Ce0.5O2catalyst with a GHSV(gas hourly space velocity)of 10,000 hr-1at 25°C.The effect of the molar ratio of O3to HCHO was also investigated.As O3/HCHO ratio was increased from 3 to 8,the removal efficiency of HCHO was increased from 83.3%to 100%.With O3/HCHO ratio of 8,the mineralization efficiency of HCHO to CO2was 86.1%.At 25°C,the p-type oxide semiconductor(Mn0.5Ce0.5O2)exhibited an excellent ozone decomposition efficiency of 99.2%,which significantly exceeded that of n-type oxide semiconductors such as Ti O2,which had a low ozone decomposition efficiency(9.81%).At a GHSV of 10,000 hr-1,[O3]/[HCHO]=3 and temperature of 25°C,a high HCHO removal efficiency(≥81.2%)was maintained throughout the durability test of 80 hr,indicating the long-term stability of the catalyst for HCHO removal. | Jia Wei Li Kuan Lun Pan Sheng Jen Yu Shaw Yi Yan Moo Been Chang | 2014 | Journal of Environmental Sciences2014，26，12： | 9 |
| 7 | Toughening Poly(lactic acid) with Imidazolium-based Elastomeric Ionomers显示文摘Imidazolium-based elastomeric ionomers(i-BIIR) were facilely synthesized by ionically modified brominated poly(isobutylene-co-isoprene)(BIIR) with different alkyl chain imidazole and thoroughly explored as novel toughening agents for poly(lactic acid)(PLA). The miscibility, thermal behavior, phase morphology and mechanical property of ionomers and blends were investigated through dynamic mechanical analyses(DMA), differential scanning calorimetry(DSC), scanning electron microscopy(SEM), tensile and impact testing. DMA and SEM results showed that better compatibility between the PLA and i-BIIR was achieved compared to the PLA/unmodified BIIR elastomer. A remarkable improvement in ductility with an optimum elongation at break up to235% was achieved for the PLA/i-BIIR blends with 1-dodecylimidazole alkyl chain(i-BIIR-12), more than 10 times higher than that of pure PLA. The impact strengths of PLA were enhanced from 1.9 kJ/m^2 to 4.1 kJ/m^2 for the PLA/10 wt% i-BIIR-12 blend. Toughening mechanism had been established by systematical analysis of the compatibility, intermolecular interaction and phase structures of the blends. Interfacial cavitations initiated massive shear yielding of the PLA matrix owing to a suitable interfacial adhesion which played a key role in the enormous toughening effect in these blends. We believed that introducing imidazolium group into the BIIR elastomer was vital for the formation of a suitable interfacial adhesion. | Lu Chen Kuan Hu Si-Ting Sun Hai Jiang Dong Huang Kun-Yu Zhang Li Pan Yue-Sheng Li | 2018 | Chinese Journal of Polymer Science2018，36，12： | 7 |
| 8 | Flexible control strategy for HVDC transmission system adapted to intermittent new energy delivery显示文摘Intermittent new energy delivery requires increasing the flexibility of ultra-high voltage direct current(DC)power adjustment.Based on a converter steady-state model and a DC power model,the control angle constraints of a converter valve are relaxed for power regulation.In this paper,a flexible DC power control method based on a fixed tap changer position is proposed.The initial ratio of the converter transformer is optimized.The effects of the fixed-tap changer position control on the control angle,reactive power compensation,and commutation failure are analyzed.The new control method allows a DC system to operate at a large angle and increase the additional reactive power loss while improving the commutation security margin.Steady-state and electromagnetic transient simulations in the CIGRE test system verify the validity of the method proposed in this paper and the correctness of the analysis conclusions. | Chenhao Li Kuan Li Changhui Ma Pengfei Zhang Qi Tao Yingtao Sun Xin Wang | 2021 | Global Energy Interconnection2021，4，4： | 6 |

| 10 | Feasibility of Tea Saponin-Enhanced Soil Washing in a Soybean Oil-Water Solvent System to Extract PAHs/Cd/Ni Efficiently from a Coking Plant Site显示文摘Mixed contaminated brownfield sites have brought serious risks to human health and environmental safety. With the purpose of removing polycyclic aromatic hydrocarbons(PAHs) and heavy metals from a coking plant site, an innovative technology for ex-situ washing was developed in the present work. The combination of 15.0 mL L^(-1) soybean oil and 7.5 g L^(-1) tea saponin proved an effective method to extract co-pollutants from soil. After two consecutive washing cycles, the efficiency rates of removal for 3-, 4-,5(+6)-ring, and total PAHs, Cd, and Ni were approximately 98.2%, 96.4%, 92.3%, 96.3%, 94.1%, and 89.4%, respectively. Meanwhile,as evaluated by Tenax extraction method and metal stability indices, the residual PAHs and heavy metals after consecutive washing mainly existed in the form with extremely low bioaccessibility in the soil. Thus, in the soil after two washing cycles, there appeared limited environmental transfer risk of co-pollutants. Moreover, a subsequent precipitation method with alkaline solution and PAHdegrading strain Sphingobium sp. PHE9 inoculation effectively removed 84.6%–100% of Cd, 82.5%–91.7% of Ni, and 92.6%–98.4% of PAHs from the first and second washing solvents. The recovered solvents also exhibited a high recycling effectiveness. Therefore, the combined cleanup strategy proposed in this study proved environmentally friendly, which also played a major role in risk assessment and management in mixed polluted sites. | YE Mao SUN Mingming XIE Shanni LIU Kuan FENG Yanfang ZHAO Yu WAN Jinzhong HU Feng LI Huixin ZONG Lianggang JIANG Xin | 2017 | Pedosphere2017，27，3： | 5 |
| 11 | Anatomical variation of infra-pyloric artery origination: A prospective multicenter observational study (IPA-Origin)显示文摘Objective: Infra-pyloric artery(IPA) is an important anatomical landmark in treatment of gastric cancer and is the key vessel for pylorus-preserving gastrectomy and subgroup of infra-pyloric lymph nodes. However, its anatomical variation is not thoroughly understood. Our study aimed to clarify the origination of the IPA.Methods: We did this prospective, multicenter, open-label, observational study at gastric surgery departments of34 hospitals in China. Gastric cancer patients aged 18 years or older and scheduled to undergo elective total or distal gastrectomy were assigned. During the surgery, IPA dissecting and exposing the origination point with photographs or video clips were required. The primary outcome was the origination of the IPA. Analysis of variance, χ~2 tests and Fisher's tests were used to analyze the differences between groups. The study is registered at Clinicaltrials.gov(No. NCT03071237).Results: Between May 8 and July 31, 2017, 429 patients were assigned for the study, and 419(97.7%) patients had the IPA dissected and recorded through photograph or video and were included in the primary outcome analysis. The median age was 62 years old, and 73.7% were male. Among the patients, 78.5% received laparoscopic surgery. Single IPA origination was identified in 398(95.0%) patients, including gastroduodenal artery(GDA) in154(36.8%) patients, anterior superior pancreaticoduodenal artery(ASPDA) in 130(31.0%) patients, and right gastroepiploic artery(RGEA) in 114(27.2%) patients. Fifteen(3.6%) patients were identified with multiple IPA and 6(1.4%) patients were identified as IPA absence. The differences in the distribution of surgical approach(P=0.003) and geographic area(P=0.030) were statistically significant. No difference was shown in sex, age,gastrectomy type, tumor location, and clinical T, N and M stage.Conclusions: Our study found that the IPA originates from GDA, ASPDA and RGEA in similar proportions.Laparoscopic surgery may be more helpful in dissection of the IPA than open surgery. | Rulin Miao Jianjun Qu Zhengrong Li Daguang Wang Jiang Yu Weidong Zang Yong Li Fenglin Liu Jian Zhang Wu Song Kai Ye Su Yan Wei Wang Shuangyi Ren Lu Zang Changqing Jing Li Zhang Kuan Wang Weihua Fu Lin Fan Bin Liang Gang Zhao Jun Cai Li Yang Jiaming Zhu Jun You Kun Yang Qingxing Huang Zhaojian Niu Ning Ning Xingfeng Qiu Gang Ji Feng Liang Hua Huang Chao Gao Fei Shan Shuangxi Li Yongning Jia Lianhai Zhang Xiangji Ying Yan Zhang Zhaode Bu Xiangqian Su Gang Zhao Ziyu Li Jiafu Ji | 2018 | Chinese Journal of Cancer Research2018，30，5： | 5 |
| 12 | m6A promotes R-loop formation to facilitate transcription termination显示文摘R-loops are three-stranded nucleic acid structures consisting of a DNA:RNA heteroduplex and a displaced single DNA strand.They constitute a prevalent genomic feature with important functions in all kingdoms of eukaryotes.1,2,3 For example,R-loops have been found over unmethylated CpG island promoters,G-rich terminators,and many other regulatory chromosomal loci.2,3 Moreover,they are essential for diverse cellular processes,such as immunoglobulin class switching,mitotic chromosome segregation,4 DNA replication and repair,genome stability regulation,5 as well as in multiple steps during transcription.6,7 R-loops can be formed both in cis and in trans;cis R-loops are formed between a nascent RNA and its DNA template following transcribing RNA polymerases and exert co-transcriptional regulatory effects.3,8 Therefore,it is important to control their formation and resolution,and many external factors have already been identified for this process.7 However,it is still unknown whether the intrinsic properties of the RNA itself,such as various modifications,can modulate the formation of DNA:RNA hybrids. | Xin Yang Qian-Lan Liu Wei Xu Yi-Chang Zhang Ying Yang Lin-Fang Ju Jing Chen Yu-Sheng Chen Kuan Li Jie Ren Qianwen Sun Yun-Gui Yang | 2019 | Cell Research2019，29，12： | 5 |
| 13 | MATRIEX imaging:multiarea two-photon real-time in vivo explorer显示文摘Two-photon laser scanning microscopy has been extensively applied to study in vivo neuronal activity at cellular and subcellular resolutions in mammalian brains.However,the extent of such studies is typically confined to a single functional region of the brain.Here,we demonstrate a novel technique,termed the multiarea two-photon real-time in vivo explorer(MATRIEX),that allows the user to target multiple functional brain regions distributed within a zone of up to 12mm in diameter,each with a field of view(FOV)of ~200μm in diameter,thus performing two-photon Ca2+imaging with single-cell resolution in all of the regions simultaneously.For example,we demonstrate real-time functional imaging of single-neuron activities in the primary visual cortex,primary motor cortex and hippocampal CA1 region of mice in both anesthetized and awake states.A unique advantage of the MATRIEX technique is the configuration of multiple microscopic FOVs that are distributed in three-dimensional space over macroscopic distances(>1 mm)both laterally and axially but that are imaged by a single conventional laser scanning device.In particular,the MATRIEX technique can be effectively implemented as an add-on optical module for an existing conventional single-beam-scanning two-photon microscope without requiring any modification to the microscope itself.Thus,the MATRIEX technique can be readily applied to substantially facilitate the exploration of multiarea neuronal activity in vivo for studies of brain-wide neural circuit function with single-cell resolution. | Mengke Yang Zhenqiao Zhou Jianxiong Zhang Shanshan Jia Tong Li Jiangheng Guan Xiang Liao Bing Leng Jing Lyu Kuan Zhang Min Li Yan Gong Zhiming Zhu Junan Yan Yi Zhou Jian K Liu Zsuzsanna Varga Arthur Konnerth Yuguo Tang Jinsong Gao Xiaowei Chen Hongbo Jia | 2019 | Light(Science & Applications)2019，8，1： | 4 |
| 14 | Reconstructing the size of individual trees using log data from cut-to-length harvesters in Pinus radiata plantations: a case study in NSW, Australia显示文摘With their widespread utilization, cut-to-length harvesters have become a major source of ‘‘big data'' for forest management as they constantly capture, and provide a daily flow of, information on log production and assortment over large operational areas. Harvester data afford the calculation of the total log length between the stump and the last cut but not the total height of trees. They also contain the length and end diameters of individual logs but not always the diameter at breast height overbark(DBHOB) of harvested stems largely because of time lapse, operating and processing issues and other system deficiencies. Even when DBHOB is extracted from harvester data, errors and/or bias of the machine measurements due to the variation in the stump height of harvested stems from that specified for the harvester head prior to harvesting and diameter measurement errors may need to be corrected. This study developed(1) a system of equations for estimating DBHOB of trees from diameter overbark(DOB) measured by a harvester head at any height up to 3 m above ground level and(2) an equation to predict the total height of harvested stems in P. radiata plantations from harvester data. To generate the data required for this purpose, cut-to-length simulations of more than 3000 trees with detailed taper measurements were carried out in the computer using the cutting patterns extracted from the harvester data and stump height survey data from clearfall operations. The equation predicted total tree height from DBHOB, total log length and the small end diameter of the top log. Prediction accuracy for total tree height was evaluated both globally over the entire data space and locally within partitioned subspaces through benchmarking statistics. These statistics were better than that of the conventional height-diameter equations for P. radiata found in the literature, even when they incorporated stand age and the average height and diameter of dominant trees in the stand as predictors. So this equation when used with harvester data would outperform the conventional equations in tree height prediction. Tree and stand reconstructions of the harvested forest is the necessary first step to provide the essential link of harvester data to conventional inventory, remote sensing imagery and Li DAR data. The equations developed in this study will provide such a linkage for the most effective combined use of harvester data in predicting the attributes of individual trees, stands and forests, and product recovery for the management and planning of P. radiata plantations in New South Wales, Australia. | Kuan Lu Huiquan Bi Duncan Watt Martin Strandgard Yun Li | 2018 | Journal of Forestry Research2018，29，1： | 4 |
| 15 | Nonlinear Parametric Vibration of a Fluid-Conveying Pipe Flexibly Restrained at the Ends显示文摘In this paper,the nonlinear parametric vibration of fluid-conveying pipes flexibly restrained at both ends and subjected to the pulsation flow excitation is investigated.The nonlinear equation of motion is derived using Hamilton^principle by considering the Kevin-Voigt viscoelastic damping,the geometric nonlinearity and the translational and rotational springs supported at the ends.The mode functions and eigen-frequencies are determined by the assumed mode method according to the elastic boundary conditions.The Galerkin method is implemented to obtain the natural frequencies and mode shapes of the pipe conveying fluid with different flow velocities.The effects of flexibly restrained conditions on stability of the pipe are analyzed.The nonlinear responses of the pipe under pulsating flow excitation are solved by the direct numerical method.The vibration behaviors are discussed in details,such as time history,frequency spectrum,phase-plane portrait,Poincare map and motion trajectory.The results show that the responses of sub-harmonic resonance and combination resonance can also be reflected in the rigidly supported pipes.The 1/5,1/8 and 1/13 sub-harmonic resonances can occur at certain excitation frequencies of the nonlinear parametric vibration system.The steady-state response amplitudes increase by a large margin and significantly affect the stability of the pipe.The effects of different spring stiffness coefficients on the parametric resonance responses are presented.For larger translational springs and rotational stiffness coefficients,the resonance frequencies shift to higher regions and the resonance amplitudes may reduce by a certain extent in accordance with the rigid-body motion.This study can provide helpful guidance on the analysis and design of piping systems subject to vibrations. | Qian Li Wei Liu Kuan Lu Zhufeng Yue | 2020 | Acta Mechanica Solida Sinica2020，33，3： | 4 |
| 16 | Turbulent characteristics and rotation correction of wall function in rotating channel with high local rotation parameter显示文摘The turbulent fluctuation and the rotation correction of wall function law are investigated in the entrance section of a rotating channel. The one-dimensional hot wire probe and the X-type probe are utilized to measure the boundary layer at four streamwise stations. Through the analysis on the boundary layer near the leading side and trailing side, it is found that the turbulent fluctuation is promoted in the trailing side whereas suppressed in the leading side. This difference is attributed to the Coriolis instability near the trailing side. In addition, considering the local rotation parameter Rc, whose maximum absolute value is 0.014, is larger than that in previous research, whose maximum value is 0.007, the whole process of the relaminarization is captured. To understand this phenomenon better, the effects of the generation term and the Coriolis term in the transport equation of the Reynolds stress are discussed. In addition, the rotation correction of the viscous-Coriolis region and the Coriolis region are discussed, a new revising method for the wall function is proposed. | Zhi TAO Huijie WU Ruquan YOU Haiwang LI Kuan WEI | 2018 | Chinese Journal of Aeronautics2018，31，10： | 4 |
| 17 | One hundred noteworthy boletes from China显示文摘Fungi of the family Boletaceae are of great importance in both ecology and economy.Our previous molecular phylogenetic studies have shown this family to have an extremely high species diversity in China.To further document the Chinese boletes,morphological studies and phylogenetic analyses were conducted including species of Boletaceae from China and other parts of the world.The results indicate that seven subfamily-level major clades and 62 generic clades can be retrieved,52 of which are found in China.Furthermore,100 species(comprising 32 genera)common in China are illustrated and described here in detail.Among them,four genera and 46 species are new to science,and 26 new combinations are proposed.To interpret the species concepts consistently,epitypes for five species are designated based on collections made from or near the type localities.Notes on eight extralimital species are also provided.Among the species reported here,most of the species are known only from East Asia.Only Leccinum scabrum(Bull.)Gray,Porphyrellus porphyrosporus(Fr.&Hok)E.-J.Gilbert and Tylopilus felleus(Bull.)P.Karst.are widely distributed in the Holarctic,and Buchwaldoboletus lignicola(Kallenb.)Pila´t;Strobilomyces strobilaceus(Scop.)Berk.are in Eurasia;while Aureoboletus mirabilis(Murrill)Halling,Harrya chromapes(Frost)Halling et al.,and Sutorius eximius(Peck)Halling et al.are found throughout East Asia-North America based on morphological and molecular phylogenetic evidences. | Gang Wu Yan-Chun Li Xue-Tai Zhu Kuan Zhao Li-Hong Han Yang-Yang Cui Fang Li Jian-Ping Xu Zhu L.Yang | 2016 | Fungal Diversity2016，，6： | 4 |

| 19 | Tunable luminescent CsPb_2Br_5 nanoplatelets:applications in light-emitting diodes and photodetectors显示文摘Unlike organic–inorganic hybrid perovskites, all-inorganic cesium lead halide perovskites hold great promise for developing high-performance optoelectronic devices, owing to their improved stability. Herein, we investigate the perovskite-related CsPb_2 Br_5 nanoplatelets(NPLs) with tunable emission wavelengths via changing the reaction temperatures to 100°C, 120°C, and 140°C. Reaction temperature plays a key role in determining the shapes and thicknesses of the resulting CsPb_2 Br_5 NPLs. A higher temperature is in favor of the formation of smaller and thicker NPLs. To develop their potential applications in optoelectronic devices, green light emitting diodes(LEDs) and photodetectors based on CsPb_2 Br_5 NPLs are fabricated. The green LEDs based on CsPb_2 Br_5 NPLs synthesized at 140°C exhibit an excellent pure green emission(full width at half-maximum of <20 nm) and display a luminous efficiency of 34.49 lm∕W under an operation current of 10 m A. Moreover, the photodetector based on CsPb_2 Br_5 NPLs synthesized at 100°C has better performance with a rise time of 0.426 s, a decay time of0.422 s, and a ratio of the current(with and without irradiation) of 364%. | CENG HAN CUNLONG LI ZHIGANG ZANG MING WANG KUAN SUN XIAOSHENG TANG JIHE DU | 2017 | Photonics Research2017，5，5： | 4 |
| 20 | The first power generation test of hot dry rock resources exploration and production demonstration project in the Gonghe Basin,Qinghai Province,China显示文摘Hot dry rock(HDR)is a kind of clean energy with significant potential.Since the 1970s,the United States,Japan,France,Australia,and other countries have attempted to conduct several HDR development research projects to extract thermal energy by breaking through key technologies.However,up to now,the development of HDR is still in the research,development,and demonstration stage.An HDR exploration borehole(with 236℃ at a depth of 3705 m)was drilled into Triassic granite in the Gonghe Basin in northwest China in 2017.Subsequently,China Geological Survey(CGS)launched the HDR resources exploration and production demonstration project in 2019.After three years of efforts,a sequence of significant technological breakthroughs have been made,including the genetic model of deep heat sources,directional drilling and well completion in high-temperature hard rock,large-scale reservoir stimulation,reservoir characterization,and productivity evaluation,reservoir connectivity and flow circulation,efficient thermoelectric conversion,monitoring,and geological risk assessment,etc.Then the whole-process technological system for HDR exploration and production has been preliminarily established accordingly.The first power generation test was completed in November 2021.The results of this project will provide scientific support for HDR development and utilization in the future. | Er-yong Zhang Dong-guang Wen Gui-ling Wang Wei-de Yan Wen-shi Wang Cheng-ming Ye Xu-feng Li Huang Wang Xian-chun Tang Wei Weng Kuan Li Chong-yuan Zhang Ming-xing Liang Hong-bao Luo Han-yue Hu Wei Zhang Sen-qi Zhang Xian-peng Jin Hai-dong Wu Lin-you Zhang Qing-da Feng Jing-yu Xie Dan Wang Yun-chao He Yue-wei Wang Zu-bin Chen Zheng-pu Cheng Wei-feng Luo Yi Yang Hao Zhang En-lai Zha Yu-lie Gong Yu Zheng Chang-sheng Jiang Sheng-sheng Zhang Xue Niu Hui Zhang Li-sha Hu Gui-lin Zhu Wen-hao Xu Zhao-xuan Niu Li Yang | 2022 | China Geology2022，5，3： | 4 |
