| 1 | Trajectory planning and yaw rate tracking control for lane changing of intelligent vehicle on curved road显示文摘The lateral control for lane changing of intelligent vehicle on curved road in automatic highway systems was studied. Based on trapezoidal acceleration profile, considering the curvature difference between starting lane and target lane, a new virtual trajectory planning method for lane changing on curved road was presented, and the calculating formulas for ideal states of vehicle in the inertial coordinate system during a lane changing maneuver were established. Applying the predetermined trajectory, the reference yaw angle and yaw rate for lane changing were generated. On the assumption that the information on yaw rate of vehicle can be measured with on-board sensors and based on the lateral dynamical model of vehicle, the yaw-rate-tracking control law was designed by applying nonsingular terminal sliding mode technology. Based on Lyapunov function method, the finite-time convergence property of the system was obtained from the phase-plane analysis. Simulation results showed that if the curvature difference between starting lane and target lane was not considered, then at the finishing time of lane changing, it was impossible to avoid the deviation of the virtual trajectory panned from the target lane, which increased with the decrease of curvature radius. With the trajectory planning method and yaw rate-tracking control law proposed in this paper and considering the curvature difference between the starting lane and target lane, the desired virtual trajectory for lane changing without deviation was obtained and the expected tracking performance was also verified by the simulation. | REN DianBo ZHANG JiYe ZHANG JingMing CUI ShengMin | 2011 | Science China(Technological Sciences)2011，54，3： | 25 |
| 2 | Spatial and temporal variations of forest LAI in China during 2000-2010显示文摘Forests are crucial terrestrial ecosystems.Their leaf area index (LAI) is a key parameter determining the exchange of matter and energy between the atmosphere and the ground surface.In this study,MOD 09A1 and MCD 43A1 data were input into an inversion model based on the 4-scale geometric optical model to retrieve 8-d 500 m LAI products in China during the period 2000 to 2010.The resulting LAI product was validated using LAI measured in 6 typical areas.The spatial and temporal variations of forest LAI and its relationships with temperature and precipitation were analyzed.The results show that the accuracy of the 500 m LAI product was above 70% in the 6 typical areas,indicating the reliability of this product.From 2000 to 2010,forest LAI in northeast,north,and south central China showed increasing trends.However,forest LAI in southeast and parts of southwest China showed downward trends,mainly because of the significant decrease observed during the period 2008 to 2010.Annual mean forest LAI positively correlated with annual mean temperature (AMT) in northeastern China and negatively correlated with AMT in southwest China.It had positive correlations with annual total precipitation in central south and north China.The abnormal climate conditions in 2001 and 2009 caused forest LAI to be obviously lower than normal in regions south of the Qinling Mountains and Huaihe River.Annual mean LAI decreased by more than 1.0 in some areas. | LIU YiBo JU WeiMin CHEN JingMing ZHU GaoLong XING BaiLing ZHU JingFang HE MingZhu | 2012 | Chinese Science Bulletin2012，57，22： | 22 |

| 4 | Performance analysis for range expansion in heterogeneous networks显示文摘In this paper,the uplink and downlink performance of a two tier heterogeneous network(HetNet)with range expansion(RE)is analyzed.Different from previous works,base stations(BSs)are modeled as a spatial Poisson point process.This model can not only capture the irregularity of the BS deployment but also lead to closed form expressions.With the analytical results,the impacts of several key parameters on the coverage and throughput performance are investigated.Our results justifies the effectiveness of RE and Pico deployment.Based on our analyses,certain attention should be made on the RE design to balance the uplink and downlink performance.Our analyses are corroborated by simulations and can thus serve as a flexible and quick guidance for system design without complicated and time consuming system level platform construction and simulation. | FEI ZeSong DING HaiChuan XING ChengWen NI JiQing KUANG JingMing | 2014 | Science China(Information Sciences)2014，57，8： | 11 |

| 6 | Multicenter study of the clinicopathological features and recurrence risk prediction model of early-stage breast cancer with low-positive human epidermal growth factor receptor 2 expression in China (Chinese Society of Breast Surgery 021)显示文摘Background:Breast cancer with low-positive human epidermal growth factor receptor 2(HER2)expression has triggered further refinement of evaluation criteria for HER2 expression.We studied the clinicopathological features of early-stage breast cancer with low-positive HER2 expression in China and analyzed prognostic factors.Methods:Clinical and pathological data and prognostic information of patients with early-stage breast cancer with low-positive HER2 expression treated by the member units of the Chinese Society of Breast Surgery and Chinese Society of Surgery of Chinese Medical Association,from January 2015 to December 2016 were collected.The prognostic factors of these patients were analyzed.Results:Twenty-nine hospitals provided valid cases.From 2015 to 2016,a total of 25,096 cases of early-stage breast cancer were treated,7642(30.5%)of which had low-positive HER2 expression and were included in the study.After ineligible cases were excluded,6486 patients were included in the study.The median follow-up time was 57 months(4-76 months).The disease-free survival rate was 92.1%at 5 years,and the overall survival rate was 97.4%at 5 years.At the follow-up,506(7.8%)cases of metastasis and 167(2.6%)deaths were noted.Multivariate Cox regression analysis showed that tumor stage,lymphvascular invasion,and the Ki67 index were related to recurrence and metastasis(P<0.05).The recurrence risk prediction model was established using a machine learning model and showed that the area under the receiving operator characteristic curve was 0.815(95%confidence interval:0.750-0.880).Conclusions:Early-stage breast cancer patients with low-positive HER2 expression account for 30.5%of all patients.Tumor stage,lymphvascular invasion,and the Ki67 index are factors affecting prognosis.The recurrence prediction model for breast cancer with low-positive HER2 expression based on a machine learning model had a good clinical reference value for predicting the recurrence risk at 5 years.Trial registration:ChiCTR.org.cn,ChiCTR2100046766. | Ling Xin Qian Wu Chongming Zhan Hongyan Qin Hongyu Xiang Ling Xu Jingming Ye Xuening Duan Yinhua Liu Chinese Society of Breast Surgery(CSBrS) Chinese Society of Surgery of Chinese Medical Association | 2022 | Chinese Medical Journal2022，，6： | 9 |
| 7 | A retrospective prognostic evaluation analysis using the 8th edition of American Joint Committee on Cancer(AJCC)cancer staging system for luminal A breast cancer显示文摘Objective: We retrospectively analyzed the clinical prognostic value of the 8th edition of the American Joint Committee on Cancer(AJCC) staging system for luminal A breast cancer.Methods: Using both the anatomic and prognostic staging in the 8th edition of AJCC cancer staging system, we restaged patients with luminal A breast cancer treated at the Breast Disease Center, Peking University First Hospital from 2008 to 2014. Follow-up data including 5-year disease free survival(DFS), overall survival(OS) and other clinic-pathological data were collected to analyze the differences between the two staging subgroups.Results: This study included 421 patients with luminal A breast cancer(median follow-up, 61 months). The 5-year DFS and OS rates were 98.3% and 99.3%, respectively. Significant differences in 5-year DFS but not OS were observed between different anatomic disease stages. Significant differences were observed in both 5-year DFS and OS between different prognostic stages. Application of the prognostic staging system resulted in assignment of 175 of 421 patients(41.6%) to a different group compared to their original anatomic stages. In total, 102 of 103 patients with anatomic stage IIA changed to prognostic stage IB, and 24 of 52 patients with anatomic stage IIB changed to prognostic stage IB, while 1 changed to prognostic stage IIIB. Twenty-two of 33 patients with anatomic stage IIIA were down-staged to IIA when staged by prognostic staging system, and the other 11 patients were down-staged to IIB. Two patients with anatomic stage IIIB were down-staged to IIIA. Among seven patients with anatomic stage IIIC cancer, two were down-staged to IIIA and four were down-staged to stage IIIB.Conclusions: The 8th edition of AJCC prognostic staging system is an important supplement to the breast cancer staging system. More clinical trials are needed to prove its ability to guide selection of proper systemic therapy and predict prognosis of breast cancer. | jingming ye wenjun wang ling xu xuening duan yuanjia cheng ling xin hong zhang shuang zhang ting li yinhua liu | 2017 | Chinese Journal of Cancer Research2017，29，4： | 8 |
| 8 | Ergodic secrecy rate of two-user MISO interference channels with statistical CSI显示文摘This paper considers a two-user multiple-input single-output(MISO) interference channel with confidential messages(IFC-CM), where the beamforming vectors at the two transmitters are jointly optimized using the closed-form Pareto-optimal parameterization. We prove that artificial noise cannot improve the secrecy rate performance, and coordinated beamforming is secrecy-rate optimal which is achieved by agreeing on the parameters between the two transmitters. We analyze the feasible set of the beamforming parameters that guarantees positiveness of the secrecy rates when the transmitters know only statistical CSI, and then analysis in the ergodic secrecy rate region is discussed. More importantly, we derive the closed form of the ergodic secrecy rates and illustrate the Pareto-optimal structure of the beamforming vectors. | FEI ZeSong NI JiQing ZHAO Di XING ChengWen WANG NiWei KUANG JingMing | 2014 | Science China(Information Sciences)2014，57，10： | 7 |
| 9 | A transient bulk flow model with circular whirl motion for rotordynamic coefficients of annular seals显示文摘Bulk flow model with perturbation simplification has been used to calculate rotordynamic coefficients in annular seals which have significant influences on the dynamic behavior of rotors in turbomachinery. In this work, a transient bulk flow model with arbitrary rotor motion is developed, and the boundary conditions and friction factor in the model are calibrated with steady Computational Fluid Dynamics(CFD) analysis. The numerical solution scheme is developed based on the finite element method to obtain the transient reaction force in the seal clearance. With a periodic circular rotor orbit, the transient forces at multiple whirling frequencies are used to evaluate the rotordynamic coefficients. The leakage flowrate of CFD analysis has good agreement with experimental results and the calibrated parameters in bulk flow model are dependent on operating conditions. Although CFD calibration improves the accuracy of the perturbed bulk flow model, the direct damping is overestimated and the cross-coupled damping is underestimated. Compared with the perturbed model, the predictions of the transient bulk flow model are more agreeable with the experiment. | Peng XIA Zhansheng LIU Xiangyu YU Jingming ZHAO | 2018 | Chinese Journal of Aeronautics2018，31，5： | 7 |
| 10 | Simulating the exchanges of carbon dioxide, water vapor and heat over Changbai Mountains temperate broad- leaved Korean pine mixed forest ecosystem显示文摘A process-based ecosystem productivity model BEPS (Boreal Ecosystem Productivity Simulator) was updated to simulate half-hourly exchanges of carbon, water and energy between the atmosphere and terrestrial ecosystem at a temperate broad-leaved Korean pine forest in the Changbai Mountains, China. The BEPSh model is able to capture the diurnal and seasonal variability in carbon dioxide, water vapor and heat fluxes at this site in the growing season of 2003. The model validation showed that the simulated net ecosystem productivity (NEP), latent heat flux (LE), sensible heat flux (Hs) are in good agreement with eddy covariance measurements with an R2 value of 0.68, 0.86 and 0.72 for NEP, LE and Hs, respectively. The simulated annual NEP of this forest in 2003 was 300.5 gC/m2, and was very close to the observed value. Driving this model with different climate scenarios, we found that the NEP in the Changbai Mountains temperate broad-leaved Korean pine mixed forest ecosystem was sensitive to climate variability, and the current carbon sink will be weakened under the condition of global warming. Furthermore, as a process-based model, BEPSh was also sensitive to physiological parameters of plant, such as maximum Rubisco activity (Vcmax) and the maximum stomatal conductance (gmax), and needs to be carefully calibrated for other applications. | WANG Qiufeng, NIU Dong, YU Guirui, REN Chuanyou, WEN Xuefa, CHEN Jingming & JU Weimin Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, Beijing 100101, China Bureau of Science and Technology for Resources and Environment, Chinese Academy of Sciences, Beijing 100864, China Department of Geography, University of Toronto, Toronto M5S 3G3, Canada Graduate School of the Chinese Academy of Sciences, Beijing 100039, China Shenyang Agricultural University, Shenyang 100161, China | 2005 | Science China Earth Sciences2005，48，z1： | 6 |
| 11 | Global Water Vapor Content Decreases from 2003 to 2012: An Analysis Based on MODIS Data显示文摘Water vapor in the earth′s upper atmosphere plays a crucial role in the radiative balance, hydrological process, and climate change. Based on the latest moderate-resolution imaging spectroradiometer(MODIS) data, this study probes the spatio-temporal variations of global water vapor content in the past decade. It is found that overall the global water vapor content declined from 2003 to 2012(slope b = –0.0149, R = 0.893, P = 0.0005). The decreasing trend over the ocean surface(b = –0.0170, R = 0.908, P = 0.0003) is more explicit than that over terrestrial surface(b = –0.0100, R = 0.782, P = 0.0070), more significant over the Northern Hemisphere(b = –0.0175, R = 0.923, P = 0.0001) than that over the Southern Hemisphere(b = –0.0123, R = 0.826, P = 0.0030). In addition, the analytical results indicate that water vapor content are decreasing obviously between latitude of 36°N and 36°S(b = 0.0224, R = 0.892, P = 0.0005), especially between latitude of 0°N and 36°N(b = 0.0263, R = 0.931, P = 0.0001), while the water vapor concentrations are increasing slightly in the Arctic regions(b = 0.0028, R = 0.612, P = 0.0590). The decreasing and spatial variation of water vapor content regulates the effects of carbon dioxide which is the main reason of the trend in global surface temperatures becoming nearly flat since the late 1990 s. The spatio-temporal variations of water vapor content also affect the growth and spatial distribution of global vegetation which also regulates the global surface temperature change, and the climate change is mainly caused by the earth's orbit position in the solar and galaxy system. A big data model based on gravitational-magmatic change with the solar or the galactic system is proposed to be built for analyzing how the earth's orbit position in the solar and galaxy system affects spatio-temporal variations of global water vapor content, vegetation and temperature at large spatio-temporal scale. This comprehensive examination of water vapor changes promises a holistic understanding of the global climate change and potential underlying mechanisms. | MAO Kebiao CHEN Jingming LI Zhaoliang MA Ying SONG Yang TAN Xuelan Yang Kaixian | 2017 | Chinese Geographical Science2017，27，1： | 6 |
| 12 | Power allocation for OFDM-based cognitive heterogeneous networks显示文摘In this paper,the capacity maximization and the spectrum utilization efficiency improvement are investigated for the Pico cells in broadband heterogeneous networks.In frequency-reuse model,the users attached to Macro base station are usually viewed as primary users,and those attached to Pico base station should be regarded as cognitive radio(CR) users.As both the primary users and the CR users communicate in parallel frequency bands,the performance of the system is limited by the mutual inter-carrier interference(ICI).In order to control ICI and maximize the achievable transmission rate of the CR users,an effective power allocation scheme is proposed to maximize the transmission rate of the CR users under a given interference threshold prescribed by the primary users.By transforming this suboptimal solution into an innovative matrix expression,the algorithm is easier to perform in practice.The simulation results demonstrate that the proposed algorithm provides a large performance gain in Pico cell capacity over the non-cooperative and equal power allocation schemes. | FEI ZeSong XING ChengWen LI Na HAN YanTao DANEV Danyo KUANG JingMing | 2013 | Science China(Information Sciences)2013，56，4： | 5 |
| 13 | A novel STING agonist-adjuvanted pan-sarbecovirus vaccine elicits potent and durable neutralizing antibody and T cell responses in mice,rabbits and NHPs显示文摘The emergence of SARS-CoV-2 variants and potentially other highly pathogenic sarbecoviruses in the future highlights the need for pan-sarbecovirus vaccines.Here,we discovered a new STING agonist,CF501,and found that CF501-adjuvanted RBD-FC vaccine(CF501/RBD-FC)elicited significantly stronger neutralizing antibody(nAb)and T cell responses than Alum-and cGAMP-adjuvanted RBD-FC in mice.Vaccination of rabbits and rhesus macaques(nonhuman primates,NHPs)with CF501/RBD-FC elicited exceptionally potent nAb responses against SARS-CoV-2 and its nine variants and 41 S-mutants,SARS-CoV and bat SARSr-CoVs.CF501/RBD-FC-immunized hACE2-transgenic mice were almost completely protected against SARS-CoV-2 challenge,even 6 months after the initial immunization.NHPs immunized with a single dose of CF501/RBD-FC produced high titers of nAbs.The immunized macaques also exhibited durable humoral and cellular immune responses and showed remarkably reduced viral load in the upper and lower airways upon SARS-CoV-2 challenge even at 108 days post the final immunization.Thus,CF501/RBD-Fc can be further developed as a novel pan-sarbecovirus vaccine to combat current and future outbreaks of sarbecovirus diseases. | Zezhong Liu Jie Zhou Wei Xu Wei Deng Yanqun Wang Meiyu Wang Qian Wang Ming Hsieh Jingming Dong Xinling Wang Weijin Huang Lixiao Xing Miaoling He Chunlin Tao Youhua Xie Yilong Zhang Youchun Wang Jincun Zhao Zhenghong Yuan Chuan Qin Shibo Jiang Lu Lu | 2022 | Cell Research2022，32，3： | 5 |
| 14 | Statistically robust resource allocation for distributed multi-carrier cooperative networks显示文摘In this paper, we investigate joint subcarrier and power allocation scheme for distributed multicarrier cooperative networks with imperfect channel state information. Using practical channel estimation algorithms, the statistic model of the channel estimation error is first derived. Then based on the channel error model, the resource allocation scheme aims at maximizing the sum rate of the overall network. Specifically, both subcarrier allocation and power allocation are taken into account. In the subcarrier allocation, a realistic problem of the power leakage between neighboring subcarriers is also addressed. Furthermore, based on Lagrange dual-decomposition algorithm, a practical power allocation algorithm is proposed. Finally, the simulation results demonstrate the performance advantages of the proposed robust design. | XING ChengWen FEI ZeSong LI Na HAN YanTao DANEV Danyo KUANG JingMing | 2013 | Science China(Information Sciences)2013，56，2： | 5 |
| 15 | Resource Allocation for Physical Layer Security in Heterogeneous Network with Hidden Eavesdropper显示文摘The tremendous performance gain of heterogeneous networks(Het Nets) is at the cost of complicated resource allocation. Considering information security, the resource allocation for Het Nets becomes much more challenging and this is the focus of this paper. In this paper, the eavesdropper is hidden from the macro base stations. To relax the unpractical assumption on the channel state information on eavesdropper, a localization based algorithm is first given. Then a joint resource allocation algorithm is proposed in our work, which simultaneously considers physical layer security, cross-tier interference and joint optimization of power and subcarriers under fairness requirements. It is revealed in our work that the considered optimization problem can be efficiently solved relying on convex optimization theory and the Lagrangian dual decomposition method is exploited to solve the considered problem effectively. Moreover, in each iteration the closed-form optimal resource allocation solutions can be obtained based on the Karush-Kuhn-Tucker(KKT) conditions. Finally, the simulation results are given to show the performance advantages of the proposed algorithm. | GONG Shiqi XING Chengwen FEI Zesong KUANG Jingming | 2016 | China Communications2016，13，3： | 5 |

| 17 | Cooperative beamforming design for physical-layer security of multi-hop MIMO communications显示文摘The security issue is critically important for wireless communications, especially for multi-hop communications. In this paper, we propose a cooperative secrecy beamforming scheme for a multi-hop MIMO communication network, in which there is a single-antenna source, multiple multi-antenna relays and a singleantenna destination. Moreover, two types of eavesdroppers exist in the network, one of which has known channel state information(CSI), while the other not. To achieve security communications, in our work null-space beamforming and artificial noise beamforming are jointly optimized to improve the secrecy rate of the multi-hop network. In nature, the joint optimization is nonconvex and challenging. Exploiting its structure, the considered optimization problem is decoupled into a series of subproblems that can be efficiently solved based on convex optimization theory. Finally, some numerical experiment results are provided to assess the performance of the proposed secrecy beamforming design. | Shiqi GONG Chengwen XING Zesong FEI Jingming KUANG | 2016 | Science China(Information Sciences)2016，59，6： | 4 |
| 18 | Wigner-Ville distribution and cross Wigner-Ville distribution of noisy signals显示文摘The Wigner-Ville distribution (WVD) and the cross Wigner-Ville distribution (XWVD) have been shown to be effcient in the estimation of instantaneous frequency (IF). But the statistical result of the IF estimation from XWVD peak is much better than using WVD peak. The reason is given from a statistical point of view. Theoretical studies show that XWVD of the analyzed signal can be estimated from XWVD of the noise-contaminated signal. The estimation is unbiased, and the variance is equal to that of noise. In this case, WVD cannot be estimated from WVD of the noise-contaminated signal. Therefore, higher SNR is required when WVD is used to analyze signals. | Chen Guanghua Ma Shiwei Liu Ming Zhu Jingming Zeng Weimin | 2008 | Journal of Systems Engineering and Electronics2008，19，5： | 4 |
| 19 | Distributed cooperative localization based on Gaussian message passing on factor graph in wireless networks显示文摘In conventional localization, agents may not be able to reach sufficient number of anchors to obtain unambiguous locations, especially in sparse networks. Cooperative localization is a promising solution in that harsh environment, which enables the agents to cooperate with each other by exchanging location information and performing range measurements. In this paper, a distributed cooperative localization method based on factor graph is proposed in wireless networks. Gaussian parametric messages are used to represent the messages passed on factor graph. However, because of the nonlinear observation model, no closed-form solutions can be obtained. To solve this problem, the Taylor expansion is used to approximate the nonlinear terms in message updating, which leads to the Gaussian message passing on factor graph. Accordingly, only two parameters of the Gaussian distribution have to be transmitted and the communication overhead for localization can be significantly reduced. The two proposed algorithms for the application with accurate and inaccurate anchors,respectively, are evaluated by Monte Carlo simulations and compared with the SPAWN and maximum likelihood(ML) estimator. The results show that the proposed algorithms can perform very close to SPAWN with much lower computational complexity, and it outperforms the ML estimator significantly. | WU Nan LI Bin WANG Hua XING ChengWen KUANG JingMing | 2015 | Science China(Information Sciences)2015，58，4： | 4 |
| 20 | Application of Self-Organizing Feature Map Neural Network Based on K-means Clustering in Network Intrusion Detection显示文摘Due to the widespread use of the Internet,customer information is vulnerable to computer systems attack,which brings urgent need for the intrusion detection technology.Recently,network intrusion detection has been one of the most important technologies in network security detection.The accuracy of network intrusion detection has reached higher accuracy so far.However,these methods have very low efficiency in network intrusion detection,even the most popular SOM neural network method.In this paper,an efficient and fast network intrusion detection method was proposed.Firstly,the fundamental of the two different methods are introduced respectively.Then,the selforganizing feature map neural network based on K-means clustering(KSOM)algorithms was presented to improve the efficiency of network intrusion detection.Finally,the NSLKDD is used as network intrusion data set to demonstrate that the KSOM method can significantly reduce the number of clustering iteration than SOM method without substantially affecting the clustering results and the accuracy is much higher than Kmeans method.The Experimental results show that our method can relatively improve the accuracy of network intrusion and significantly reduce the number of clustering iteration. | Ling Tan Chong Li Jingming Xia Jun Cao | 2019 | Computers, Materials & Continua2019，，7： | 4 |
