| 1 | Principles and methods for the validation of quantitative remote sensing products显示文摘We first discuss the relativity of 'true value and homogeneity' for quantitative remote sensing products (QRSPs), and then propose the definitions of 'eigenaccuracy' and 'eigenhomogeneity' under practical conditions. The eigenaccuracy and eigenhomogeneity for land surface crucial parameters such as albedo, leaf area index (LAI), and surface temperature are analyzed based on a series of experiments. Secondly, we point out the differences and similarities between the scale-free phenomena of the QRSPs and the measurements of the coastline length (1-dimensional) and the curved surface area (2-dimensional). An information fractal algorithm for the QRSPs is presented. In a case study for the LAI, when the fractal dimension is 2.16, the ratio of the LAI retrieval values obtained respectively from remote sensing data of 30 m and 6 km pixel resolution can actually reach as high as 2.86 for the same 6 km pixel using the same retrieval model. Finally, we propose an operational validation method 'one test and two matches' and multipoint observation when the real situation does not allow carrying out scanning measurement without gap and overlap on the ground surface. | RenHua Zhang Jing Tian ZhaoLiang Li HongBo Su ShaoHui Chen XinZhai Tang | 2010 | Science China Earth Sciences2010，53，5： | 27 |
| 2 | Analysis and Numerical Simulation of Rolling Contact between Sphere and Cone显示文摘In non-conforming rolling contact, the contact stress is highly concentrated in the contact area. However, there are some limitations of the special contact model and stress model used for the theoretical study of the phenomenon, and this has prevented in-depth analysis of the associated friction, wear, and failure. This paper is particularly aimed at investigating the area of rolling contact between a sphere and a cone, for which purpose the boundary is determined by the Hertz theory and the geometries of the non-conforming surfaces. The phenomenon of stick-slip contact is observed to occur in the contact area under the condition of no-full-slip(Q < μ·P). Using the two-dimensional rolling contact theory developed by CARTER, the relative positions of the stick and slip regions and the distribution of the tangential force over the contact area are analyzed. Furthermore, each stress component is calculated based on the Mc Ewen theory and the idea of narrow band. The stress equations for the three-dimensional rolling contact between the sphere and the cone are obtained by the principle of superposition, and are used to perform some numerical simulations. The results show that the stress components have a large gradient along the boundary between the stick and slip regions, and that the maximum stress is inversely proportional to the contact coefficient and proportional to the friction coefficient. A new method for investigating the stress during non-classical three-dimensional rolling contact is proposed as a theoretical foundation for the analysis of the associated friction, wear, and failure. | ZHAO Yanling XIA Chengtao WANG Hongbo XUAN Jiaping XIANG Jingzhong LIU Xianli SU Xiangguo | 2015 | Chinese Journal of Mechanical Engineering2015，28，3： | 18 |
| 3 | Bio-leaching effects of Leptospirillum ferriphilum on the surface chemical properties of pyrite显示文摘Leptospirillum ferriphilum cultured using different energy sources(either soluble ferrous ion or pyrite) changed the surface properties of pyrite.Cell adsorption,zeta-potential,hydrophobicty,FT-IR spectra and surface morphology were investigated.Adhesion of bacterial cells to the pyrite surface is a fast process.Furthermore,the adsorption of cells grown in pyrite is greater than of cells grown in soluble ferrous ion.The Iso-Electric Point(IEP) of pyrite treated with L.ferriphilum approaches that of the cells themselves.The contact angle of the pyrite surface was observed to decrease due to the surface formation of some hydrophilic substances during bio-leaching.Changes in pyrite surface properties after bacterial treatment support the idea that ferric ion plays an important role and that indirect bio-oxidation is the principal mechanism of pyrite bio-leaching. | GU, Guohua SU, Lijun CHEN, Minglian SUN, Xiaojun ZHOU, Hongbo | 2010 | Mining Science and Technology2010，20，2： | 14 |
| 4 | Characteristics of the lunar samples returned by the Chang'E-5 mission显示文摘Forty-five years after the Apollo and Luna missions returned lunar samples,China's Chang’E-5(CE-5)mission collected new samples from the mid-latitude region in the northeastern Oceanus Procellarum of the Moon.Our study shows that 95%of CE-5 lunar soil sizes are found to be within the range of 1.40-9.35μm,while 95%of the soils by mass are within the size range of 4.84-432.27μm.The bulk density,true density and specific surface area of CE-5 soils are 1.2387 g/cm^(3),3.1952 g/cm^(3) and 0.56 m^(2)/g,respectively.Fragments from the CE-5 regolith are classified into igneous clasts(mostly basalt),agglutinate and glass.A few breccias were also found.The minerals and compositions of CE-5 soils are consistent with mare basalts and can be classified as low-Ti/low-Al/low-K type with lower rare-earth-element contents than materials rich in potassium,rare earth element and phosphorus.CE-5 soils have high FeO and low Mg index,which could represent a new class of basalt. | Chunlai Li Hao Hu Meng-Fei Yang Zhao-Yu Pei Qin Zhou Xin Ren Bin Liu Dawei Liu Xingguo Zeng Guangliang Zhang Hongbo Zhang Jianjun Liu Qiong Wang Xiangjin Deng Caijin Xiao Yonggang Yao Dingshuai Xue Wei Zuo Yan Su Weibin Wen Ziyuan Ouyang | 2022 | National Science Review2022，9，2： | 12 |
| 5 | LUCC and its impact on run-off yield in the Bai River catchment—upstream of the Miyun Reservoir basin显示文摘Aims The Miyun Reservoir is the most important drinking water source for Beijing—the capital of China with a population of more than 16 million.Since the 1980s,the inflow to the reservoir has been decreasing,which seriously threatens the security of water use in Beijing.Our goal was to analyze the impact of land use and cover change(LUCC)on run-off yield in the upstream of the Miyun Reservoir.Methods In this study,the Soil andWater Assessment Tool(SWAT)was used to simulate the impacts of LUCC on the run-off yield in the Bai River catchment—upstream of the Miyun Reservoir basin in northern China.The investigation was conducted using two 6-year historical streamflow records:from 1986 to 1991 and from 2000 to 2005.A split sample procedure was used for model calibration and validation.The data from 1986 to 1988 and from 2000 to 2002 were used for calibration,while those from 1989 to 1991 and from 2003 to 2005 for validation.The SWAT calibration was based on monthly measured discharge at Zhangjiafen station at the catchment outlet from Bai River catchment.Additionally,the influence of LUCC on the surface run-off was distinguished from that of climate change on the surface runoff through SWAT scenarios modeling,the twoway analysis of variance(ANOVA),and the rainfall–run-off double-mass analysis in the Bai River catchment.Important Findings We found that the SWAT model could be used successfully to accurately simulate run-off yield and different LUCC patterns affecting water quantity in this catchment.During calibraion for the two periods the simulated monthly run-off satisfactorily matched the observed values,with the Nash–Sutcliffe coefficient>0.9 and 0.7 and a coefficient of determination of 0.9 and 0.65 at the outlet station(Zhangjiafen station),while during validation for the two periods the obtained values were 0.85,0.65 and 0.9,0.65,respectively.During the period of 1986–91,both the SWAT scenarios modeling and the analysis of the two-way ANOVA method showed that LUCC and climate change had some impact on run-off,and the impact of climate change was more significant than that of LUCC.Compared with the period during 1986–91,the run-off yield in the period during 2000–05 significantly decreased.The obtained results from the rainfall–run-off double-mass analysis indicate that since 1998 LUCC has had an increasing influence on the run-off,while the response of the run-off to rainfall has been decreasing.Since 1998,the LUCC has been a major driving force for run-off change in Bai River catchment. | Chesheng Zhan Zongxue Xu Aizhong Ye Hongbo Su | 2011 | Journal of Plant Ecology2011，4，1： | 12 |

| 8 | Stream-computing of High Accuracy On-board Real-time Cloud Detection for High Resolution Optical Satellite Imagery显示文摘This paper focuses on the time efficiency for machine vision and intelligent photogrammetry, especially high accuracy on-board real-time cloud detection method. With the development of technology, the data acquisition ability is growing continuously and the volume of raw data is increasing explosively. Meanwhile, because of the higher requirement of data accuracy, the computation load is also becoming heavier. This situation makes time efficiency extremely important. Moreover, the cloud cover rate of optical satellite imagery is up to approximately 50%, which is seriously restricting the applications of on-board intelligent photogrammetry services. To meet the on-board cloud detection requirements and offer valid input data to subsequent processing, this paper presents a stream-computing of high accuracy on-board real-time cloud detection solution which follows the “bottom-up” understanding strategy of machine vision and uses multiple embedded GPU with significant potential to be applied on-board. Without external memory, the data parallel pipeline system based on multiple processing modules of this solution could afford the “stream-in, processing, stream-out” real-time stream computing. In experiments, images of GF-2 satellite are used to validate the accuracy and performance of this approach, and the experimental results show that this solution could not only bring up cloud detection accuracy, but also match the on-board real-time processing requirements. | Mi WANG Zhiqi ZHANG Zhipeng DONG Shuying JIN Hongbo SU | 2019 | Journal of Geodesy and Geoinformation Science2019，2，2： | 7 |

| 10 | Energy Efficiency and Spectrum Efficiency in Underlay Device-to-Device Communications Enabled Cellular Networks显示文摘In this paper, we investigate the energy efficiency and spectrum efficiency, including one-hop device-to-device(D2D) communications mode and two-way amplify-and-forward(AF) relaying D2D communications mode in underlay D2D communications enabled cellular networks. An analysis of average energy efficiency and spectrum efficiency are developed and closed-form expressions are obtained for two types of D2D communications modes under the effect of Rayleigh fading channel, path loss, and co-channel interference. Analytical results are validated through numerical simulations. Based on the simulation, the effects of the interference, the distance between D2D pair and the position of relay node on the energy efficiency and spectrum efficiency of D2D communications are investigated. The optimal D2D transmission powers of these two modes to maximize the energy efficiency are also investigated. | Yan Cai Yiyang Ni Jun Zhang Su Zhao Hongbo Zhu | 2019 | China Communications2019，16，4： | 5 |
| 11 | Trajectory prediction of cyclist based on dynamic Bayesian network and long short-term memory model at unsignalized intersections显示文摘Cyclist trajectory prediction is of great significance for both active collision avoidance and path planning of intelligent vehicles.This paper presents a trajectory prediction method for the motion intention of cyclists in real traffic scenarios.This method is based on dynamic Bayesian network(DBN)and long short-term memory(LSTM).The motion intention of cyclists is hard to predict owing to potential large uncertainties.The DBN is used to infer the distribution of cyclists’intentions at intersections to improve the prediction time.The LSTM with encoder-decoder is used to predict the cyclists’trajectories to improve the accuracy of prediction.Therefore,the DBN and LSTM are adopted to guarantee prediction accuracy and improve the prediction time.The experiment results are presented to show the effectiveness of the predict strategies. | Hongbo GAO Hang SU Yingfeng CAI Renfei WU Zhengyuan HAO Yongneng XU Wei WU Jianqing WANG Zhijun LI Zhen KAN | 2021 | Science China(Information Sciences)2021，64，7： | 4 |

| 13 | Multi-channel radar array design method and algorithm显示文摘The array design of radar antenna is no more a new problem at all. Nevertheless, the array design of multi-channel radar, especially that of MIMO (multiple-input multiple-output) radar, is a new problem. The performance of space diversion and spatial sampling of target scattering are dependent on the array design of MIMO radar, and consequently, which in turn will determine the performances of target parameter estimation, DOA, and imaging. In this paper, commencing with target scattering model, T/R signal model of MIMO radar, and spatial sampling ability for this system are analyzed. Conceptually, under the far field condition, spatial convolution principle determines the array design theory. Based on this idea, array design method and also algorithm are proposed in this paper. | SU Yi ZHU YuTao YU WenXian XU HongBo LEI WenTai | 2010 | Science China(Information Sciences)2010，53，7： | 3 |
| 14 | Neodymium-doped Yttrium Aluminum Garnet Transparent Laser Ceramics Prepared by Co-precipitation Method显示文摘Transparent polycrystalline neodymium-doped yttrium aluminum garnet ceramics (Nd∶YAG) with better chemical stability, excellent optical and high temperature mechanical property is becoming a new laser host material. The Nd∶YAG precursor powders with loosely dispersed, slightly agglomerated and YAG cubic crystal phase were synthesized at 1100 ℃ by the co-precipitation method combined with the reverse strike, using Nd2O3, Y2O3, Al(NO3)3·9H2O and NH4HCO3 as raw materials, (NH4)2SO4 as electrical stabilizer, TEOS as sintering additive. The Nd∶YAG transparent ceramics were fabricated after being sintered at 1700 ℃ in vacuum for 5 h. The Nd∶YAG ceramic materials were characterized by the TG-DTA, XRD, FT-IR, TEM, FT-PL and FEG-ESEM. The results show that the precursor powders are amorphous at 800 ℃, the large amount YAlO3(YAP) and tiny amout Y3Al5O 12(YAG) appear when the calcination temperature is 890 ℃ and the YAP hexagonal crystal phase transforms to YAG cubic crystal phase at 1012 ℃. There are agglomerations in the precursor powders resulting from the high calcination temperature and the agglomerates link together, but as a whole the particles distribute homogeneously. The lasing wavelength of (Nd 0.01Y 0.99)3Al5O 12 transparent ceramics is 1.065 μm and there exists a slight red-shift compared to the single crystal with the same chemical composition. With the optical wavelength increasing, the transmittance of (Nd 0.01Y 0.99)3Al5O 12 raises gradually and the optical transmittance is about 45% in the visible light and 58% in the infrared light. | Su Chunhui Song Qiong Zhang Huashan Zhang Hongbo Hou Zhaoxia Shao Jing | 2006 | Journal of Rare Earths2006，24，1： | 2 |

| 18 | High-dimensional immune profiling by mass cytometry revealed immunosuppression and dysfunction of immunity in COVID-19 patients显示文摘The outbreak of coronavirus disease 2019(COVID-19)caused by the new virus SARS-CoV-2 has been announced as a public health emergency of international concern.1–3 The clinical features of patients with COVID-19 range from common fever and cough to other rare symptoms,such as diarrhea and nausea.This disease can progress quickly,and 2–3%of patients die within a short time,which is generally due to multiple organ failure.4–7 Clinically,COVID-19 patients are classified into mild,moderate,severe,and critical cases.5–7 The immune response against SARS-CoV-2 is probably linked to the severity of disease.Recently,Zheng et al.8 showed that elevated levels of T-cell exhaustion and reduced functional diversity of T cells in peripheral blood may predict severe progression in COVID-19 patients;however,a more comprehensive understanding of the pathology of SARS-CoV-2 infection remains to be delineated.Here,we profiled immune cellular components using mass cytometry(CyTOF)to analyze the peripheral blood mononuclear cells(PBMCs)from patients with differences in disease progression by comparing with the PBMCs from healthy donors(HDs). | Wenjing Wang Bin Su Lijun Pang Luxin Qiao Yingmei Feng Yabo Ouyang Xianghua Guo Hongbo Shi Feili Wei Xiaogang Su Jiming Yin Ronghua Jin Dexi Chen | 2020 | Cellular & Molecular Immunology2020，17，6： | 2 |
| 19 | Intercomparison of two trapezoid-based soil moisture downscaling methods using three scaling factors显示文摘This paper compared two soil moisture downscaling methods using three scaling factors.Level 3 soil moisture product of advanced microwave scanning radiometer for EOS(AMSR-E)is downscaled from 25 to 1 km.The downscaled results are compared with the soil moisture observations from polarimetric scanning radiometer(PSR)microwave radiometer and field sampling.The results show that(1)the scaling factor of normalized soil thermal inertia(NSTIs)and vegetation temperature condition index(VTCI)are better than soil evaporative efficiency in reflecting soil moisture;(2)for method 1,NSTIS is the best in the downscaling of soil moisture.For method 2,VTCI is the best;(3)no significant differences of the correlation coefficients(R2)and the biases were found between the two methods for the same scaling factors.However,method 2 shows a better potential than method 1 in the time-series applications of the downscaling of soil moisture;(4)compared with the relationship between the area-averaged soil moisture of AMSR-E and that of PSR,R2 of the 6 sets of the downscaled soil moisture almost do not decrease,which suggests the validity of the downscaling of soil moisture with the two downscaling methods using the three scaling factors. | Jing Tian Xiangzheng Deng Hongbo Su | 2019 | International Journal of Digital Earth2019，12，4： | 1 |
