| 2 | Prostate cancer identification: quantitative analysis of T2-weighted MR images based on a back propagation artificial neural network model显示文摘Computer-aided diagnosis(CAD) systems have been proposed to assist radiologists in making diagnostic decisions by providing helpful information. As one of the most important sequences in prostate magnetic resonance imaging(MRI), image features from T2-weighted images(T2WI) were extracted and evaluated for the diagnostic performances by using CAD. We extracted 12 quantitative image features from prostate T2-weighted MR images. The importance of each feature in cancer identification was compared in the peripheral zone(PZ) and central gland(CG), respectively. The performance of the computer-aided diagnosis system supported by an artificial neural network was tested. With computer-aided analysis of T2-weighted images, many characteristic features with different diagnostic capabilities can be extracted. We discovered most of the features(10/12) had significant difference(P<0.01) between PCa and non-PCa in the PZ, while only five features(sum average, minimum value, standard deviation, 10 th percentile, and entropy) had significant difference in CG. CAD prediction by features from T2 w images can reach high accuracy and specificity while maintaining acceptable sensitivity. The outcome is convictive and helpful in medical diagnosis. | ZHAO Kai WANG ChengYan HU Juan YANG XueDong WANG He LI FeiYu ZHANG XiaoDong ZHANG Jue WANG XiaoYing | 2015 | Science China(Life Sciences)2015，58，7： | 16 |
| 3 | Quantitative analysis of diffusion-weighted magnetic resonance images:differentiation between prostate cancer and normal tissue based on a computer-aided diagnosis system显示文摘Diffusion-weighted imaging(DWI) is considered to be one of the dominant modalities used in prostate cancer(PCa) detection and the assessment of lesion aggressiveness,especially for peripheral zone(PZ) PCa.Computer-aided diagnosis(CAD),which is capable of automatically extracting and evaluating image features,can integrate multiple parameters and improve the detection of PCa.In this study,13 quantitative image features were extracted from DWI by CAD,and diagnostic efficacy was analyzed in both the PZ and transition zone(TZ).The results demonstrated that there was a significant difference(P<0.05) between PCa and non-PCa for nine of the 13 features in the PZ and five of the 13 features in the TZ.Besides,the prediction outcome of CAD had a strong correlation with the DWI scores that were graded by experienced radiologists according to the Prostate Imaging-Reporting and Data System Version 2(PI-RADS v2). | Ge Gao Chengyan Wang Xiaodong Zhang Juan Hu Xuedong Yang He Wang Jue Zhang Xiaoying Wang | 2017 | Science China(Life Sciences)2017，60，1： | 13 |
| 4 | Initial analysis for characterizing and mitigating the pseudorange biases of BeiDou navigation satellite system显示文摘Pseudorange bias has become a practical obstacle in the field of high-precision global navigation satellite system(GNSS)applications,which greatly restricts the further development of high-precision applications.Unfortunately,no studies have been conducted on the pseudorange biases of the BeiDou navigation satellite system(BDS).To mitigate the effects of pseudorange biases on the BDS performance to the greatest extent possible,the origin of such BDS pseudorange biases are first thoroughly illustrated,based upon which the dependency of the biases on the receiver configurations are studied in detail.Owing to the limitations regarding the parameter re-settings for hardware receivers,software receiver technology was used to achieve the ergodicity of the receiver parameters,such as the correlator spacing and front-end bandwidth,using high-fidelity signal observations collected by a 40-m-high gain dish antenna at Haoping Observatory.Based on this,the pseudorange biases of the BDS B1I and B3I signals and their dependency on different correlator spacings and front-end bandwidths were adequately provided.Finally,herein,the suggested settings of the correlator spacing and front-end bandwidth for BDS receivers are in detail proposed for the first time.As a result,the pseudorange biases of the BDS signals will be less than 20 cm,reaching even under 10 cm,under this condition.This study will provide special attention to GNSS pseudorange biases,and will significantly promote a clear definition of the appropriate receiver parameter settings in the interface control documents of BDS and other individual satellite systems. | Chengyan He Xiaochun Lu Ji Guo Chengeng Su Wei Wang Meng Wang | 2020 | Satellite Navigation2020，1，1： | 7 |

| 6 | On the Response of the Global Subduction Rate to Global Warming in Coupled Climate Models显示文摘The response of the global subduction rate to global warming was assessed based on a set of Intergovernmental Panel on Climate Change(IPCC) Fourth Assessment Report(AR4) models. It was found that the subduction rate of the global ocean could be significantly reduced under a warming climate, as compared to a simulation of the present-day climate. The reduction in the subduction volume was quantitatively estimated at about 40 Sv and was found to be primarily induced by the decreasing of the lateral induction term due to a shallower winter mixed layer depth. The shrinking of the winter mixed layer would result from intensified stratification caused by increased heat input into the ocean under a warming climate. A reduction in subduction associated with the vertical pumping term was estimated at about 5 Sv. Further, in the Southern Ocean, a significant reduction in subduction was estimated at around 24 Sv, indicating a substantial contribution to the weakening of global subduction. | LIU Chengyan WANG Zhaomin | 2014 | Advances in Atmospheric Sciences2014，31，1： | 6 |
| 7 | On the Response of Subduction in the South Pacific to an Intensification of Westerlies and Heat Flux in an Eddy Permitting Ocean Model显示文摘Based on an eddy permitting ocean general circulation model, the response of water masses to two distinct climate scenarios in the South Pacific is assessed in this paper. Under annually repeating atmospheric forcing that is characterized by different westerlies and associated heat flux, the response of Subantarctic Mode Water(SAMW) and Antarctic Intermediate Water(AAIW) is quantitatively estimated. Both SAMW and AAIW are found to be warmer, saltier and denser under intensified westerlies and increased heat loss. The increase in the subduction volume of SAMW and AAIW is about 19.8 Sv(1 Sv =10~6m^3s^(-1)). The lateral induction term plays a dominant role in the changes in the subduction volume due to the deepening of the mixed layer depth(MLD). Furthermore, analysis of the buoyancy budget is used to quantitatively diagnose the reason for the changes in the MLD. The deepening of the MLD is found to be primarily caused by the strengthening of heat loss from the ocean to the atmosphere in the formation region of SAMW and AAIW. | Chengyan LIU Zhaomin WANG Bingrui LI Chen CHENG Ruibin XIA | 2017 | Advances in Atmospheric Sciences2017，34，4： | 5 |
| 8 | Optimal yield-related attributes of irrigated rice for high yield potential based on path analysis and stability analysis显示文摘Improvement of yield in rice(Oryza sativa L.) is vital for ensuring food security in China. Both rice breeders and growers need an improved understanding of the relationship between yield and yield-related traits. New indica cultivars(53 in 2007 and 48 in 2008) were grown in Taoyuan,Yunnan province, to identify important components contributing to yield. Additionally, two standard indica rice cultivars with similar yield potentials, II You 107(a large-panicle type) and Xieyou 107(a heavy-panicle type), were planted in Taoyuan, Yunnan province and Nanjing,Jiangsu province, from 2006 to 2008 to evaluate the stability of yield and yield-related attributes.Growth duration(GD), leaf area index(LAI), panicles per m2(PN), and spikelets per m2(SM) were significantly and positively correlated with grain yield(GY) over all years. Sequential path analysis identified PN and panicle weight(PW) as important first-order traits that influenced grain yield. All direct effects were significant, as indicated by bootstrap analysis. Yield potential varied greatly across locations but not across years. Plant height(PH), days from heading to maturity(HM), and grain weight(GW) were stable traits that showed little variation across sites or years, whereas GD(mainly the pre-heading period, PHP) and PN varied significantly across locations. To achieve a yield of 15 t ha-1, a cultivar should have a PH of 110–125 cm, a long GD with HM of approximately 40 days, a PN of 300–400 m-2, and a GW of 29–31 mg. | Ganghua Li Jun Zhang Congdang Yang Yunpan Song Chengyan Zheng Shaohua Wang Zhenghui Liu Yanfeng Ding | 2014 | The Crop Journal2014，2，4： | 4 |
| 9 | Hydrocarbon accumulation characteristics of beachbar sandstones in the southern slope of the Dongying Sag, Jiyang Depression, Bohai Bay Basin, China显示文摘A number of beach-bar sandstone reservoir beds are developed in the upper fourth member of the Eocene Shahejie Formation(Ess4) on the southern slope of the Dongying Sag. Based on the analysis of seismic and logging data, with characterization and petrographic studies of core and cutting samples, this paper analyzes the hydrocarbon accumulation characteristics in two typical blocks of the Boxing and Wangjiagang oilfields, especially reservoir bed heterogeneity and migration conditions that influence oil and gas distribution, calculates the index of reservoir bed quality(IRQ) with a mathematical method, and discusses the relationship between driving force and resistance of hydrocarbon accumulation. Taking into account the characteristics of thin interbeds in beach-bar sandstones, an experimental model simulated the characteristics of hydrocarbon migration and accumulation in thin interbedded sandstones with reservoir bed heterogeneity. The results showed that hydrocarbon distribution and properties were extremely non-uniform. Reservoir bed and migration conditions controlled hydrocarbon accumulation in beach-bar sandstones. IRQ is above 0.4 in the main hydrocarbon region. Sand body distribution, structural configuration and fault systems controlled the direction of regional migration and location of hydrocarbon accumulation. Simulation experiments indicated that the change of driving force for hydrocarbon migration affected selective accumulation mechanisms. Hydrocarbon moved vertically along fault zones to the reservoir and resulted in the distribution of hydrocarbon in the reservoir. Two kinds of hydrocarbon accumulation models exist in the study area. One is a hydrocarbon accumulation model controlled by reservoir bed heterogeneity and the second is a hydrocarbon accumulation model controlled by a complex migration system with faults connecting sandbodies. Finally, different exploration strategies should be adopted for the detailed exploration for beach-bar sandstone reservoirs according to different geological backgrounds. | Guo Song Tan Lijuan Lin Chengyan Li Hongnan Lü Xiuxiang Wang Hongtao | 2014 | Petroleum Science2014，11，2： | 4 |
| 10 | Discovery of the Proterozoic low-grade metamorphicsubmarine carbonatite lavas in China显示文摘The carbonatite lavas found in the Kunyang Group were formed in submarine extrusive environment. Many igneous features (e.g. colors, textures, structures, minerals, inclusions) are clear. But most of their petrologic characteristics are different from typical carbonatites over the world. Most petrologic details of the rocks are given by comparison with other carbonatites and adjacent sedimentary dolomites. The discovery of the lavas proves that the carbonatite volcano also existed in Kunyang rift. | Yongbei Zhang Qirong Wei Chengyan Xiu Hao Wang | 1998 | Chinese Science Bulletin1998，43，5： | 4 |
| 11 | Efficient recovery of valuable metals from waste printed circuit boards by microwave pyrolysis显示文摘The recycling of waste printed circuit board(WPCBs) is of great significance for saving resources and protecting the environment. In this study, the WPCBs were pyrolyzed by microwave and the contained valuable metals Cu, Sn and Pb were recovered from the pyrolyzed WPCBs. The effect of pyrolysis temperature and time on the recovery efficiency of valuable metals was investigated. Additionally, the characterization for morphology and surface elemental distribution of pyrolysis residues was carried out to investigate the pyrolysis mechanism. The plastic fiber boards turned into black carbides, and they can be easily separated from the metals by manual. The results indicate that 91.2%, 96.1% and 94.4% of Cu, Sn and Pb can be recovered after microwave pyrolysis at 700 °C for 60 minutes. After pyrolysis, about 79.8%(mass)solid products, 11.9%(mass) oil and 8.3%(mass) gas were produced. These gas and oil can be used as fuel and raw materials of organic chemicals, respectively. This process provides an efficient and energy-saving technology for recovering valuable metals from WPCBs. | Yubo Liu Jialiang Zhang Xu Yang Wenguang Yang Yongqiang Chen Chengyan Wang | 2021 | Chinese Journal of Chemical Engineering2021，34，12： | 2 |
| 12 | Evaluation of Arctic Sea Ice Drift and its Relationship with Near-surface Wind and Ocean Current in Nine CMIP6 Models from China显示文摘The simulated Arctic sea ice drift and its relationship with the near-surface wind and surface ocean current during 1979-2014 in nine models from China that participated in the sixth phase of the Coupled Model Intercomparison Project(CMIP6)are examined by comparison with observational and reanalysis datasets.Most of the models reasonably represent the Beaufort Gyre(BG)and Transpolar Drift Stream(TDS)in the spatial patterns of their long-term mean sea ice drift,while the detailed location,extent,and strength of the BG and TDS vary among the models.About two-thirds of the models agree with the observation/reanalysis in the sense that the sea ice drift pattern is consistent with the near-surface wind pattern.About the same proportion of models shows that the sea ice drift pattern is consistent with the surface ocean current pattern.In the observation/reanalysis,however,the sea ice drift pattern does not match well with the surface ocean current pattern.All nine models missed the observational widespread sea ice drift speed acceleration across the Arctic.For the Arctic basin-wide spatial average,five of the nine models overestimate the Arctic long-term(1979-2014)mean sea ice drift speed in all months.Only FGOALS-g3 captures a significant sea ice drift speed increase from 1979 to 2014 both in spring and autumn.The increases are weaker than those in the observation.This evaluation helps assess the performance of the Arctic sea ice drift simulations in these CMIP6 models from China. | Xiaoyong YU Chengyan LIU Xiaocun WANG Jian CAO Jihai DONG Yu LIU | 2022 | Advances in Atmospheric Sciences2022，39，6： | 2 |
| 13 | Comprehensive utilization of complex rubidium ore resources:Mineral dissociation and selective leaching of rubidium and potassium显示文摘Currently,the process of extracting rubidium from ores has attracted a great deal of attention due to the increasing application of rubidium in high-technology field.A novel process for the comprehensive utilization of rubidium ore resources is proposed in this paper.The process consists mainly of mineral dissociation,selective leaching,and desilication.The results showed that the stable silicon–oxygen tetrahedral structure of the rubidium ore was completely disrupted by thermal activation and the mineral was completely dissociated,which was conducive to subsequent selective leaching.Under the optimal conditions,extractions of 98.67% Rb and 96.23%K were obtained by leaching the rubidium ore.Moreover,the addition of a certain amount of activated Al(OH)_(3) during leaching can effectively inhibit the leaching of silicon.In the meantime,the leach residue was sodalite,which was successfully synthesized to zeolite A by hydrothermal conversion.The proposed process provided a feasible strategy for the green extraction of rubidium and the sustainable utilization of various resources. | Quankuang Zhang Baozhong Ma Chengyan Wang Yongqiang Chen Wenjuan Zhang | 2023 | International Journal of Minerals,Metallurgy and Materials2023，30，5： | 2 |
| 14 | Evidence for metasomatic mantle carbonatitic magma extrusion in Mesoproterozoic ore-hosting dolomite rocks in the middle Kunyang rift, central Yunnan, China显示文摘The Kunyang rift lying on the western margin of the Yangtze platform is a rare Precambrian Fe-Cu mineralization zone. WudingLufeng basin that is an important part of the zone is located on the west edge in the middle of the rift. The most important ore-hosting rocks are Mesoproterozoic dolomite rocks in the basin controlled by a ring fracture system, which is a fundamental structure of the basin. Plenty of silicate minerals and acicular apatite, feldspar phenocrysts and small vesicular, flown line and flown plane structures, melt inclusion and high temperature fluid inclusion found in most ore-hosting dolomites suggest that this kind of rocks could not be sedimentary dolomite, marble or hydrothermal carbonate rocks. The Zr/Hf and Nb/Ta values of the rocks are identical with those of associated mantle-derived rocks, and vary widely. For the monomineral dolomite, d18OSMOW‰ = +5.99 to +18.4 and d13CPDB‰ = à3.01 to +0.94, which fall within the range for all carbonatitic volcanic rocks of the world. As for the accessory minerals, the values of d18OSMOW‰ of magnetite (=+3.47 to +5.99‰) are close to that of the mantle (<5.7%), and the d34S‰ values of sul?des (à5.09 to +5.78, averaging +1.50) are close to that of meteorite. For all the ore-bearing dolomite rocks, eNd = +0.19 to +2.27, and the calculated ISr = 0.699143, while for the associated mantle-derived rocks, eNd = +3.18 to +3.72. All the data suggest that the mineral assemblage is not only igneous but also of metasomatic mantle origin. And the presence of acicular apatite indicates that the rocks were formed by magma rapidly cooling. And the phenocryst texture and vesicular, flown and ropy and pyroclastic structures suggest that the igneous rocks were extrusive. Therefore, the ore-bearing dolomite rocks are carbonatitic volcanic rocks. This conclusion implies that most iron and copper ore deposits hosted in the dolomite rocks should be of the carbonatite type. | Yongbei Zhang Hua Bi Longshi Yu Shihua Sun Jiaxiang Qiu Chengyan Xu Hao Wang Renjing Wang | 2008 | Progress in Natural Science:Materials International2008，18，8： | 2 |
| 15 | On the determination and simulation of seawater freezing point temperature under high pressure显示文摘At present,it is believed that the freezing point temperature of seawater is a function of salinity and pressure,and the freezing point is a key parameter in a coupled air-sea-ice system.Generally,empirical formulas or methods are used to calculate the freezing point of seawater.Especially in high-pressure situations,e.g.,under a thick ice sheet or ice shelf,the pressure term must be taken into account in the determination of seawater freezing point temperature.This study summarized various methods that have been used to calculate seawater freezing point with high pressure.The methods that were employed in two ocean-ice models were also assessed.We identified the disadvantages of these methods used in these two models and addressed the corresponding uncertainties of the freezing point temperature formulas.This study provides useful information on the calculation of the freezing point temperature in numerical modeling and indicates a need to investigate the sensitivity of numerical simulations to the uncertainties in the freezing point temperature in future. | YAN Liangjun WANG Zhaomin LIU Chengyan WU Yang | 2019 | Advances in Polar Science2019，30，4： | 2 |
| 16 | Impacts of High-Frequency Atmospheric Forcing on Southern OceanCirculation and Antarctic Sea Ice显示文摘The relative contributions of atmospheric fluctuations on 6 h?2 d,2?8 d,and 8 d?1 month time scales to the changes in the air?sea fluxes,the SO circulation,and Antarctic sea ice are investigated.It was found that the imposed forcing variability on the three time scales creates a significant increase in wind power input,and hence an increase of about 50%,97%,and 5%of eddy kinetic energy relative to the simulation driven by monthly forcing,respectively.Also,SO circulation and the strength of the upper cell of meridional overturning circulation become strengthened.These results indicate more dominant effects of atmospheric variability on the 2?8 d time scale on the SO circulation.Meanwhile,the 6 h?2 d(2?8 d)atmospheric variability causes an increase in the total sea-ice extent,area,and volume,by about 33%,30%,and 19%(17%,20%,and 25%),respectively,relative to those in the experiment forced by monthly atmospheric variables.Such significant sea-ice increases are caused by a cooler ocean surface and stronger sea-ice transports owing to the enhanced heat losses and air-ice stresses induced by the atmospheric variability at 6 h?2 d and 2?8 d,while the effects of the variability at 8 d?1 month are rather weak.The influences of atmospheric variability found here mainly result from wind fluctuations.Our findings in this study indicate the importance of properly resolving high-frequency atmospheric variability in modeling studies. | Yang WU Zhaomin WANG Chengyan LIU and Xia LIN | 2020 | Advances in Atmospheric Sciences2020，37，5： | 1 |

| 18 | Recommendation for Cardiac Magnetic Resonance Imaging-Based Phenotypic Study:Imaging Part显示文摘Cardiac magnetic resonance(CMR)imaging provides important biomarkers for the early diagnosis of many cardiovascular diseases and has been reported to reveal phenome-wide associations of cardiac/aortic structure and functionality in popula-tion studies.Nevertheless,due to the complexity of operation and variations among manufactural vendors,magnetic field strengths,coils,sequences,scan parameters,and image analysis approaches,CMR is rarely used in large cohort studies.Existing guidelines mainly focused on the diagnosis of cardiovascular diseases,which did not aim to basic research.The purpose of this study was to propose a recommendation for CMR based phenotype measurements for cohort study.We classify the imaging sequences of CMR into three categories according to the importance and universality of correspond-ing measurable phenotypes.The acquisition time and repeatability of the phenotypic measurement were also taken into consideration during the categorization.Unlike other guidelines,this recommendation focused on quantitative measurement of large amount of phenotypes from CMR. | Chengyan Wang Yan Li Jun Lv Jianhua Jin Xumei Hu Xutong Kuang Weibo Chen He Wang | 2021 | Phenomics2021，1，4： | 1 |
| 19 | Tumor extracellular vesicles mediate anti-PD-L1 therapyresistance by decoying anti-PD-L1显示文摘PD-L1+tumor-derived extracellular vesicles(TEVs)cause systemic immunosuppression and possibly resistance to anti-PD-L1 antibody(αPD-L1)blockade.However,whether and how PD-L1+TEVs mediateαPD-L1 therapy resistance is unknown.Here,we show that PD-L1+TEVs substantially decoyαPD-L1 and that TEV-boundαPD-L1 is more rapidly cleared by macrophages,causing insufficient blockade of tumor PD-L1 and subsequentαPD-L1 therapy resistance.Inhibition of endogenous production of TEVs by Rab27a or Coro1a knockout reversesαPD-L1 therapy resistance.Either an increasedαPD-L1 dose or macrophage depletion mediated by the clinical drug pexidartinib abolishesαPD-L1 therapy resistance.Moreover,in the treatment cycle with the same total treatment dose ofαPD-L1,high-dose and low-frequency treatment had better antitumor effects than low-dose and highfrequency treatment,induced stronger antitumor immune memory,and eliminatedαPD-L1 therapy resistance.Notably,in humanized immune system mice with human xenograft tumors,both increasedαPD-L1 dose and high-dose and low-frequency treatment enhanced the antitumor effects ofαPD-L1.Furthermore,increased doses ofαPD-L1 andαPD-1 had comparable antitumor effects,butαPD-L1 amplified fewer PD-1+Treg cells,which are responsible for tumor hyperprogression.Altogether,our results reveal a TEV-mediated mechanism ofαPD-L1-specific therapy resistance,thus providing promising strategies to improveαPD-L1 efficacy. | Jiming Chen Jie Yang Wenhui Wang Danfeng Guo Chengyan Zhang Shibo Wang Xinliang Lu Xiaofang Huang Pingli Wang Gensheng Zhang Jing Zhang Jianli Wang Zhijian Cai | 2022 | Cellular & Molecular Immunology2022，19，11： | 1 |
| 20 | Investigation of Nanosecond Pulsed Discharge and Its Audio Characteristics in Atmospheric-pressure Air显示文摘There was no well-resolved mechanism of audible noise caused by corona discharge on UHV transmission lines. Hence we measured the sound pressure of pulsed discharges between needle-plane electrodes under different discharge conditions in air, for revealing the intrinsic relationship between discharge and its audible noise(AN). The relationship between discharge parameters and audio characte- ristics was drawn from the analysis of the electric and sound signals obtained in experiments. Experiment results showed that nanosecond pulsed discharges produce the sound pressure with a microsecond pulse lagging behind the discharge pulse in their waveforms. The peak value of the sound pulse decreases and its high frequency component gradually attenuates, when the measuring distance from discharges increases. The sound pulses correlate with the discharge current and voltage significantly, especially the current. The audible noise produced by repetitive pulsed discharge increases with the strength, duration, and pulse repetition rate of discharge. | REN Chengyan | 2013 | 高电压技术2013，39，8： | 1 |
