| 1 | Monitoring mine collapse by D-InSAR显示文摘For harmful ground collapse and its special deformation characteristics,which causes SAR images to lose coherence,InSAR technology cannot be applied in monitoring surface collapse in mining areas.We took the Shenmu mining area in northern Shaanxi province as an example to study subsidence in mining areas and proposed an interpolated multi-view processing method.The results show that this method can improve the detectable deformation gradient to a certain extent and can become a good reference value for monitoring large scale gradient deformation.We also analyzed the rules for temporal decorrelation in mining. | YANG Chengsheng ZHANG Qin ZHAO Chaoying JI Lingyun ZHU Wu | 2010 | Mining Science and Technology2010，20，5： | 21 |
| 2 | Soil pH impact on microbial tetraether lipids and terrestrial input index (BIT) in China显示文摘The distributions of microbial tetraether lipids i.e. glycerol dialkyl glycerol tetraethers (GDGTs) were investigated in a variety of Chinese soils featured by a wide range of pH values in different climate zones. The bacterial branched GDGTs and archaeal isoprenoid GDGTs were found to be widely distributed in Chinese soils and their relative abundance was controlled primarily by soil pH. The bacterial bGDGTs usually dominate over archaeal iGDGTs in abundance when the soil pH is below 8.0. However archaeal iGDGTs become dominant and the abundance of halophilic archaea characterized by GDGT V without cyclopentyl ring increases dramatically in the alkaline soil with pH greater than 8.0. The relative abundance of archaeal iGDGTs to bacterial bGDGTs was defined here as RAI index. The RAI index decreases with elevated soil pH and a linear correlation is found between them indicating that the relative abundance of archaeal iGDGTs to bacterial bGDGTs increases with increased pH. The RAI index thus could be a novel proxy of the pH values of paleosol. The terrestrial input index BIT (Branched and Isoprenoid Tetraethers Index) decreases with increased soil pH suggesting that soil pH should be taken into consideration when the terrestrial contribution to marine sediments is estimated by BIT index. Moreover the TEX86 index cannot be used to reconstruct sea surface temperature in the sediments featured by a large terrestrial input. | YANG Huan DING WeiHua WANG JinXiang JIN ChengSheng HE GangQiang QIN YangMin XIE ShuCheng | 2012 | Science China Earth Sciences2012，55，2： | 19 |
| 3 | Fingerprint Liveness Detection Based on Multi-Scale LPQ and PCA显示文摘Fingerprint authentication system is used to verify users' identification according to the characteristics of their fingerprints.However,this system has some security and privacy problems.For example,some artificial fingerprints can trick the fingerprint authentication system and access information using real users' identification.Therefore,a fingerprint liveness detection algorithm needs to be designed to prevent illegal users from accessing privacy information.In this paper,a new software-based liveness detection approach using multi-scale local phase quantity(LPQ) and principal component analysis(PCA) is proposed.The feature vectors of a fingerprint are constructed through multi-scale LPQ.PCA technology is also introduced to reduce the dimensionality of the feature vectors and gain more effective features.Finally,a training model is gained using support vector machine classifier,and the liveness of a fingerprint is detected on the basis of the training model.Experimental results demonstrate that our proposed method can detect the liveness of users' fingerprints and achieve high recognition accuracy.This study also confirms that multi-resolution analysis is a useful method for texture feature extraction during fingerprint liveness detection. | Chengsheng Yuan Xingming Sun Rui Lv | 2016 | China Communications2016，13，7： | 12 |
| 4 | Effects of dry-wet cycles on three-dimensional pore structure and permeability characteristics of granite residual soil using X-ray micro computed tomography显示文摘Due to seasonal climate alterations,the microstructure and permeability of granite residual soil are easily affected by multiple dry-wet cycles.The X-ray micro computed tomography(micro-CT)acted as a nondestructive tool for characterizing the microstructure of soil samples exposed to a range of damage levels induced by dry-wet cycles.Subsequently,the variations of pore distribution and permeability due to drywet cycling effects were revealed based on three-dimensional(3D)pore distribution analysis and seepage simulations.According to the results,granite residual soils could be separated into four different components,namely,pores,clay,quartz,and hematite,from micro-CT images.The reconstructed 3D pore models dynamically demonstrated the expanding and connecting patterns of pore structures during drywet cycles.The values of porosity and connectivity are positively correlated with the number of dry-wet cycles,which were expressed by exponential and linear functions,respectively.The pore volume probability distribution curves of granite residual soil coincide with the χ^(2)distribution curve,which verifies the effectiveness of the assumption of χ^(2)distribution probability.The pore volume distribution curves suggest that the pores in soils were divided into four types based on their volumes,i.e.micropores,mesopores,macropores,and cracks.From a quantitative and visual perspective,considerable small pores are gradually transformed into cracks with a large volume and a high connectivity.Under the action of dry-wet cycles,the number of seepage flow streamlines which contribute to water permeation in seepage simulation increases distinctly,as well as the permeability and hydraulic conductivity.The calculated hydraulic conductivity is comparable with measured ones with an acceptable error margin in general,verifying the accuracy of seepage simulations based on micro-CT results. | Ran An Lingwei Kong Xianwei Zhang Chengsheng Li | 2022 | Journal of Rock Mechanics and Geotechnical Engineering2022，14，3： | 7 |
| 5 | Spatiotemporal variability of ocean chemistry in the early Cambrian,South China显示文摘Following the Ediacaran metazoan radiation,the 'Cambrian Explosion' set up the major framework of todays' animal phyla as well as modern marine ecosystem.Here,we present a preliminary investigation on the temporal and spatial(from shallow to deep waters) variations of the early Cambrian ocean chemistry in South China through analyzing a Fe-S-C systematic dataset integrated from literature.Our investigation indicates that the early Cambrian deep ocean in South China was still anoxic and Fe2+-enriched(i.e.,ferruginous) although its surface was oxic,and in between a metastable euxinic(anoxic and sulfidic) water zone may have dynamically developed in anoxic shelf waters with an increasing weathering sulfate supply.Furthermore,accompanying marine transgression and regression cycles in the early Cambrian,such a 'sandwich' structure in ocean redox chemistry demonstrates five evolutional stages,which can be well correlated to the spatiotemporal patterns of fossil records in South China.The good correlation between metazoan fossil occurrences and water chemistry in South China suggests that early animals possibly possessed ability to inhabit anoxic but generally not euxinic environments as free H2S was fatal to most eukaryotes.This view can well explain why those small shell fauna and sponges disappeared from shelf to slope areas where sulfidic Ni-Mo-rich shales were widely deposited.Thus,we conclude that the spatiotemporal variations of ocean chemistry and its biological effects probably played a key role in the phased animal radiations and 'extinctions' in the early Cambrian. | JIN ChengSheng LI Chao PENG XingFang CUI Hao SHI Wei ZHANG ZiHu LUO GenMing XIE ShuCheng | 2014 | Science China Earth Sciences2014，57，4： | 5 |
| 6 | Identification of key gene networks controlling organic acid and sugar metabolism during watermelon fruit development by integrating metabolic phenotypes and gene expression profiles显示文摘The organoleptic qualities of watermelon fruit are defined by the sugar and organic acid contents,which undergo considerable variations during development and maturation.The molecular mechanisms underlying these variations remain unclear.In this study,we used transcriptome profiles to investigate the coexpression patterns of gene networks associated with sugar and organic acid metabolism.We identified 3 gene networks/modules containing 2443 genes highly correlated with sugars and organic acids.Within these modules,based on intramodular significance and Reverse Transcription Quantitative polymerase chain reaction(RT-qPCR),we identified 7 genes involved in the metabolism of sugars and organic acids.Among these genes,Cla97C01G000640,Cla97C05G087120 and Cla97C01G018840(r^(2)=0.83 with glucose content)were identified as sugar transporters(SWEET,EDR6 and STP)and Cla97C03G064990(r^(2)=0.92 with sucrose content)was identified as a sucrose synthase from information available for other crops.Similarly,Cla97C07G128420,Cla97C03G068240 and Cla97C01G008870,having strong correlations with malic(r^(2)=0.75)and citric acid(r^(2)=0.85),were annotated as malate and citrate transporters(ALMT7,CS,and ICDH).The expression profiles of these 7 genes in diverse watermelon genotypes revealed consistent patterns of expression variation in various types of watermelon.These findings add significantly to our existing knowledge of sugar and organic acid metabolism in watermelon. | Muhammad Jawad Umer Luqman Bin Safdar Haileslassie Gebremeskel Shengjie Zhao Pingli Yuan Hongju Zhu M.O.Kaseb Muhammad Anees Xuqiang Lu Nan He Chengsheng Gong Wenge Liu | 2020 | Horticulture Research2020，7，1： | 4 |
| 7 | Active sites in CO2 hydrogenation over confined VOx-Rh catalysts显示文摘Metal oxide-promoted Rh-based catalysts have been widely used for CO2 hydrogenation,especially for the ethanol synthesis.However,this reaction usually suffers low CO2 conversion and alcohols selectivity due to the formation of byproducts methane and CO.This paper describes an efficient vanadium oxide promoted Rh-based catalysts confined in mesopore MCM-41.The Rh-0.3VO/MCM-41 catalyst shows superior conversion(〜12%)and ethanol selectivity(〜24%)for CO2 hydrogenation.The promoting effect can be attributed to the synergism of high Rh dispersion by the confinement effect of MCM-41 and the formation of VOr-Rh interface sites.Experimental and theoretical results indicate the formation of til-CO at VOv-Rh interface sites is easily dissociated into*CH X,and then*CH X can be inserted by CO to form CH3,*CO followed by CH3*CO hydrogenation to ethanol. | Guishuo Wang Ran Luo Chengsheng Yang Jimin Song Chuanye Xiong Hao Tian Zhi-Jian Zhao Rentao Mu Jinlong Gong | 2019 | Science China Chemistry2019，62，12： | 4 |
| 8 | Noise Reduction for InSAR Phase Images Using BM3D显示文摘This paper extends the application of Block-matching(BM) and 3D transform-domain collaborative filtering(BM3D) to the noise reduction in Interferometric synthetic aperture radar(In SAR) phase imagery,and proposes a denoising algorithm which can effectively remove noise and preserve fringes. Since the noise level estimated by a median estimator is not always optimal for proposed algorithm in wavelet domain, a method of calculating optimal noise standard deviation is also developed.The proposed algorithm is efficient and robust. Experimental results show that the visual quality and evaluation indexes of proposed algorithm outperform other filters for both simulated and real In SAR images. | ZHANG Wenge ZHANG Qin ZHAO Chaoying YANG Chengsheng ZOU Weibao | 2014 | Chinese Journal of Electronics2014，23，2： | 3 |
| 9 | Fuzzy Logic QoS Dynamic Source Routing for Mobile Ad Hoc Networks显示文摘Considering the characters of dynamic topology and the imprecise state information in mobile ad hoc network,we propose a Fuzzy Logic QoS Dynamic Source Routing (FLQDSR) algorithm based on Dynamic Source Routing (DSR) protocol while adopting fuzzy logic to select the appropriate QoS routing in multiple paths which are searched in parallel. This scheme considers not only the bandwidth and end-to-end delay of routing, but also the cost of the path. On the otherh and the merit of using fuzzy logic is that it can be implemented by hardware. This makes the realization of the scheme easier and faster. However our algorithm is based on DSR, the maximal hop count should be less than 10, i.e., the scale of mobile ad hoc network should not be very large. Simulation results show that.FLQDSR can tolerate a high degree of information imprecision by adding the fuzzy logic module which integrates the QoS requirements of application and the routing QoS parameters to determine the most qualified one in every node. | ZHANGXu CHENGSheng FENGMei-yu DINGWei | 2004 | The Journal of China Universities of Posts and Telecommunications2004，11，4： | 3 |

| 11 | Fingerprint Liveness Detection from Different Fingerprint Materials Using Convolutional Neural Network and Principal Component Analysis显示文摘Fingerprint-spoofing attack often occurs when imposters gain access illegally by using artificial fingerprints,which are made of common fingerprint materials,such as silicon,latex,etc.Thus,to protect our privacy,many fingerprint liveness detection methods are put forward to discriminate fake or true fingerprint.Current work on liveness detection for fingerprint images is focused on the construction of complex handcrafted features,but these methods normally destroy or lose spatial information between pixels.Different from existing methods,convolutional neural network(CNN)can generate high-level semantic representations by learning and concatenating low-level edge and shape features from a large amount of labeled data.Thus,CNN is explored to solve the above problem and discriminate true fingerprints from fake ones in this paper.To reduce the redundant information and extract the most distinct features,ROI and PCA operations are performed for learned features of convolutional layer or pooling layer.After that,the extracted features are fed into SVM classifier.Experimental results based on the LivDet(2013)and the LivDet(2011)datasets,which are captured by using different fingerprint materials,indicate that the classification performance of our proposed method is both efficient and convenient compared with the other previous methods. | Chengsheng Yuan Xinting Li Q.M.Jonathan Wu Jin Li Xingming Sun | 2017 | Computers, Materials & Continua2017，，4： | 3 |
| 12 | Secure Authentication Protocol for Mobile Payment显示文摘With the increasing popularity of fintech, i.e., financial technology, the e-commerce market has grown rapidly in the past decade, such that mobile devices enjoy unprecedented popularity and are playing an everincreasing role in e-commerce. This is especially true of mobile payments, which are attracting increasing attention.However, the occurrence of many traditional financial mishaps has exposed the challenges inherent in online authentication technology that is based on traditional modes of realizing the healthy and stable development of mobile payment. In addition, this technology ensures user account security and privacy. In this paper, we propose a Secure Mutual Authentication Protocol(SMAP) based on the Universal 2 nd Factor(U2 F) protocol for mobile payment. To guarantee reliable service, we use an asymmetric cryptosystem for achieving mutual authentication between the server and client, which can resist fake servers and forged terminals. Compared to the modes currently used, the proposed protocol strengthens the security of user account information as well as individual privacy throughout the mobile-payment transaction process. Practical application has proven the security and convenience of the proposed protocol. | Kai Fan Hui Li Wei Jiang Chengsheng Xiao Yintang Yang | 2018 | Tsinghua Science and Technology2018，23，5： | 3 |
| 13 | CGR-QV: A Virtual Topology DTN Routing Algorithm Based on Queue Scheduling显示文摘In this paper,we proposed a CGR-QV algorithm in order to solve the problems of low message delivery rate and low throughput problems in deep space communication networks,which are caused by the high delay,asymmetric data transmission rate,and frequent topology switching characteristics.The proposed method separate different message types in the queues,establish the relationship between TTL,wait time and Hurst to prevent the phenomenon of'starvation'and redundancy.In view of the impact of congestion on the network,improved algorithm use the Elastic load balancing strategy establish the relationship between optimal thresholdsαand network performance reliability.Simulation result show that the algorithm has improved in throughput as about 19%,message delivery rate improved as about 7.5%and bandwidth rejection rate decreased as about 4.7%,the algorithm can balance the impact of topology updates and resource consumption better in space communication networks. | Yaowen Qi Li Yang Chengsheng Pan Hanrui Li | 2020 | China Communications2020，17，7： | 3 |
| 14 | Evolution of cracks in the shear bands of granite residual soil显示文摘The evolution of shear bands and cracks plays an important role in landslides.However,there is no systematic method for classification of the cracks,which can be used to analyze the evolution of cracks in shear bands.In this study,X-ray computed tomography(CT)is used to observe the behavior of granite residual soil during a triaxial shear process.Based on the digital volume correlation(DVC)method,a crack classification method is established according to the connectivity characteristics of cracks before and after loading.Cracks are then divided into six classes:obsolete,brand-new,isolated,split,combined,and compound.With evolution of the shear bands,a large number of brand-new cracks accelerate the damages of materials at the mesoscale,resulting in a sharp decrease in strength.The volume of brandnew cracks increases rapidly with increasing axial strain,and their volume is greater than 50%when the strain reaches 12%,while the volume of compound cracks decreases from 54%to 21%.As cracks are the weakest areas in a material,brand-new cracks accelerate the development of shear bands.Finally,the coupling effect of shear bands and cracks destroys the soil strength. | Chengsheng Li Lingwei Kong Ran An | 2022 | Journal of Rock Mechanics and Geotechnical Engineering2022，14，6： | 3 |

| 16 | A novel CD4+CTL subtype characterized by chemotaxis and inflammation is involved in the pathogenesis of Graves’orbitopathy显示文摘Graves*orbitopathy(GO),the most severe manifestation of Graves'hyperthyroidism(GH),is an autoimmune-mediated inflammatory disorder,and treatments often exhibit a low efficacy.CD4+T cells have been reported to play vital roles in GO progression.To explore the pathogenic CD4-f T cell types that drive GO progression,we applied single-cell RNA sequencing(scRNA-Seq),T cell receptor sequencing(TCR-Seq),flow cytometry,immunofluorescence and mixed lymphocyte reaction(MLR)assays to evaluate CD4+T cells from GO and GH patients.scRNA-Seq revealed the novel GO-spedfic cell type CD4+cytotoxic T lymphocytes(CTLs),which are characterized by chemotactic and inflammatory features.The clonal expansion of this CD4+CTL population,as demonstrated by TCR-Seq,along with their strong cytotoxic response to autoantigens,localization in orbital sites,and potential relationship with disease relapse provide strong evidence for the pathogenic roles of GZMB and IFN-y-secreting CD4+CTLs in GO.Therefore,cytotoxic pathways may become potential therapeutic targets for GO. | Yue Wang Ziyi Chen Tingjie Wang Hui Guo Yufeng Liu Ningxin Dang Shiqian Hu Liping Wu Chengsheng Zhang Kai Ye Bingyin Shi | 2021 | Cellular & Molecular Immunology2021，18，3： | 2 |
| 17 | End-to-End Latency Evaluation of the Sat5G Network Based on Stochastic Network Calculus显示文摘Simultaneous use of heterogeneous radio access technologies to increase the performance of real-time,reliability and capacity is an inherent feature of satellite-5G integrated network(Sat5G).However,there is still a lack of theoretical characterization of whether the network can satisfy the end-to-end transmission performance for latency-sensitive service.To this end,we build a tandem model considering the connection relationship between the various components in Sat5G network architecture,and give an end-to-end latency calculation function based on this model.By introducing stochastic network calculus,we derive the relationship between the end-to-end latency bound and the violation probability considering the traffic characteristics of multimedia.Numerical results demonstrate the impact of different burst states and different service rates on this relationship,which means the higher the burst of arrival traffic and the higher the average rate of arrival traffic,the greater the probability of end-to-end latency violation.The results will provide valuable guidelines for the traffic control and cache management in Sat5G network. | Huaifeng Shi Chengsheng Pan Li Yang Debin Wei Yunqing Shi | 2020 | Computers, Materials & Continua2020，，11： | 2 |
