| 1 | Form-fnding methods for deployable mesh reflector antennas显示文摘Deployable high-frequency mesh reflector antennas for future communications and observations are required to obtain high gain and high directivity.In order to support these new missions,reflectors with high surface accuracy are widely required.The form-fnding analysis of deployable mesh reflector antennas becomes more vital which aims to determine the initial surface profle formed by the equilibrium prestress distribution in cables to satisfy the surface accuracy requirement.In this paper,two form-fnding methods for mesh reflector antennas,both of which include two steps,are proposed.The frst step is to investigate the prestress design only for the cable net structure as the circumferential nodes connected to the supporting truss are assumed fxed.The second step is to optimize the prestress distribution of the boundary cables connected directly to the supporting truss considering the elastic deformation of the antenna structure.Some numerical examples are carried out and the simulation results demonstrate the proposed form-fnding methods can warrant the deformed antenna reflector surface matches the one by design and the cable tension forces fall in a specifed range. | Li Tuanjie Jiang Jie Deng Hanqing Lin Zhanchao Wang Zuowei | 2013 | Chinese Journal of Aeronautics2013，26，5： | 15 |

| 3 | Geochemical characteristics of the Permian Changxing Formation reef dolomites,northeastern Sichuan Basin,China显示文摘The recent discovery of deep and ultra-deep gas reservoirs in the Permian Changxing Formation reefs, northeastern Sichuan Basin is a significant development in marine carbonate oil & gas exploration in China. Reef dolomites and their origins have been major research topics for sedimentologists and oil & gas geologists. The petrography, trace element and isotope geochemistry of the reef dolomites indicated that the dolomites are characterized by low Sr and Mn contents, relatively low Fe contents, very similar δ 13 C and δ 18 O values and very different 87 Sr/ 86 Sr ratios. Although the calculated results of the fluid mixing suggested that a mixture with 85%-95% meteoric water and 5%-15% seawater seemed to be the dolomitizing fluids of the reef dolomites, the low Mn contents, relatively low Fe contents, high δ 13 C values and high homogenization temperatures of the dolomites did not support that there were large proportions of meteoric water in the dolomitization process, and the 87 Sr/ 86 Sr ratios which were close to coeval seawater also did not support the possibility of the mixture of deep-burial circulated fluids from clastic rocks. High temperature deep-burial circulated seawater with low Mn and Fe contents, high Sr content and high δ 13 C values from the dissolution of widely distributed Triassic evaporites during the burial diagenetic processes (including dehydration of water-bearing evaporites) could have been the dolomitizing fluids of the reef dolomites. | Hu Zuowei Huang Sijing Li Zhiming Zhang Yingying Xu Ershe Qi Shichao | 2013 | Petroleum Science2013，10，1： | 6 |

| 5 | Carbon isotope composition and comparison of Lower Triassic marine carbonate rocks from Southern Longmenxia section in Guang'an, Sichuan Basin显示文摘The Early Triassic was a period of ecological restoration for the earth's system after the end-Permian mass extinction.Geochemical records linked to the variations in marine ecosystems during this period have attracted the interest of geologists for many years.Based on petrographic analysis of samples and evaluations of their reliability as proxies for original seawater,this study investigated the carbon and oxygen isotopic compositions of 350 carbonate rock samples from the Lower Triassic(and adjacent strata)in the southern Longmenxia section of Guang'an,eastern Sichuan Basin.The results indicate that the Triassic carbonate rocks from the southern Longmenxia section favorably preserved the original seawater'sδ^(13)C signal.Furthermore,carbon and oxygen isotopic compositions are found to be poorly correlated,with a determination coefficient as low as 0.0205 and only 44 rock samples show results of Mn/Sr>2 and/orδ^(18)0<-6.5‰.The complete carbon isotopic curve for the Lower Triassic is established using the data from the remaining 306 samples with Mn/Sr<2 and/orδ^(18)O>-6.5‰.This curve presents favorable comparability on a global scale,specifically in theδ^(13)C minima near the Permian-Triassic boundary,at the top of the Jia1 and within the the Jia3,as well as in theδ^(13)C maxima at the tops of the Ye1 and Ye4,at the base of the Jia2 and at the top of the Ye3.The peaks and troughs corresponding to these maxima and minima all reflect global signals.By comparing these results to previous research on coeval carbon isotopic curves established within the chronostratigraphic framework,the ages of these critical evolution points are determined.The results show that the Ye1 roughly corresponds to the Griesbachian substage;the Ye2 through Ye4 correspond to the Dienerian substage;Jial corresponds to the Smithian substage;from the Jia2 to the lower part of the Jia4 correspond to the Spathian substage;and the middle and upper parts of the Jia4 belongs to the Aegean Substage of the Middle Triassic.Around the boundary between the Jial and Jia2(which represents the Smithian-Spathian boundary(SSB)),the value ofδ^(13)C increases rapidly from-0.911‰to 3.679‰.The span during which the seawater's carbon isotope experiences this drastic change may be less than36 kyr.The oxygen isotope,which is more sensitive to sedimentary environmental changes,exhibits changes prior to the carbon isotope near the SSB,indicating a significant increase in the salinity of the seawater before a sharp rise in the carbon isotope;this event leads to the formation of evaporites and dolomites. | HUANG SiJing HUANG KeKe ZHONG YiJiang LI XiaoNing MAO XiaoDong HU ZuoWei LIU SiBing ZHANG Meng WU WenHui | 2017 | Science China Earth Sciences2017，60，1： | 4 |
| 6 | Temperatures of dolomitizing fluids in the Feixianguan Formation from the Northeastern Sichuan Basin显示文摘The discovery of natural gas reservoirs from the Triassic Feixianguan Formation in the Northeastern Sichuan Basin is an important breakthrough in the field of marine carbonate rocks for Chinese oil and gas exploration in recent years.Because of the dolomite-hosted reservoirs in the Feixianguan Formation,these dolomites and their formation mechanisms have been a research focus for sedimentary geologists and petroleum geologists.Based on the homogenization temperatures of fluid inclusions,oxygen isotopic composition and their calculated temperatures,and the burial and thermal history of the typical well,it is considered that the majority of dolomites are formed by low-temperature dolomitizing fluids in the Triassic Feixianguan Formation,Northeastern Sichuan Basin.Only a minority of dolomites are formed by high-temperature dolomitizing fluids.The ending depth interval of low-temperature dolomitizing fluids was about 1000-2500 m,of which the correspondingly ending timing interval was approximately from early-middle Middle Triassic to early-middle Late Triassic.The main depth interval of high-temperature dolomitizing fluids was about 3200-4500 m,of which the correspondingly main timing interval was approximately early-middle Middle Jurassic.The low-temperature and high-temperature dolomitizing fluids have different meanings to the formation and evolution of the pore volumes of dolomite reservoirs in the Feixianguan Formation,Northeastern Sichuan Basin. | HU ZuoWei HUANG SiJing LI ZhiMing QING HaiRuo FAN Ming LAN YeFang | 2012 | Science China Earth Sciences2012，55，10： | 4 |
| 7 | ^(99m)Tc-3P_4 -RGD_2 radiotracers for SPECT/CT of esophageal tumor显示文摘In recent years,several RGD(Arg-Gly-Asp)-based radiotracers have already been successfully tested in human for the visualization of integrin αvβ3,demonstrating its feasibility in tumor diagnosis.In this paper,we evaluated the 99mTc-3P4-RGD2 single photon emission computed tomography/computerized tomography(SPECT/CT)in patients suffering from space occupying disease of esophagus.40 patients(34 males and 6 female;mean age: 58.3 years) with a suspected space occupying lesion of esophagus were included,thus finally obtaining their definite pathologic diagnosis(malignant,n=32;benign,n=8).All patients underwent endoscopic,barium esophagography and SPECT/CT imaging preoperatively.The chest SPECT was performed at 4 h after administration of99mTc-3P4-RGD2 with a dose of 939±118 MBq.The diagnosis precision,sensitivity and specificity among these methods were compared.The relationship between radioactive uptake and clinical pathological stage of esophageal carcinoma was discussed by calculating the tumor to normal esophagus(T/N).Meanwhile,the integrin αvβ3 expression was assessed immunohistochemically in postoperative esophageal tissues.31 patients were diagnosed as esophageal carcinoma;and 1,leiomyosarcoma;and 6.leimyoma;and 2,esophageal tuberculosis.The accuracy,sensitivity and specificity of barium esophagography,endoscopic and SPECT/CT imaging are 92.5/93.8/87.5%,97.5/96.9/100%,and 90/90.6/87.5%,respectively.Abnormal accumulation of radiotracer in 29 malignant lesions is observed.The SPECT/CT imaging displayed the region of radioactive uptake and lesions matched extremely with the T/N ratio from 1.31 to 2.79(mean 2.04).A case with pulmonary metastases and a case with mediastinal lymph node metastases were found which were missed by barium esophagography and endoscopic.The99mTc-3P4-RGD2 uptake of the esophageal carcinoma masses had no relevance to the tumor pathologic classification(P>0.05).There was a significant positive correlation between T/N ratio and positive cell percentage of integrin αvβ3(r=0.976),demonstrating the certain clinical potential in the diagnosis of esophageal carcinoma. | GAO Shi MA Qingjie WEN Qiang JIA Bing LIU Zhaofei CHEN Zuowei ZHANG Haishan LI Dandan | 2013 | Nuclear Science and Techniques2013，24，4： | 3 |
| 8 | 3D Shape Reconstruction of Lumbar Vertebra From Two X-ray Images and a CT Model显示文摘Structure reconstruction of 3 D anatomy from biplanar X-ray images is a challenging topic. Traditionally, the elastic-model-based method was used to reconstruct 3 D shapes by deforming the control points on the elastic mesh. However, the reconstructed shape is not smooth because the limited control points are only distributed on the edge of the elastic mesh.Alternatively, statistical-model-based methods, which include shape-model-based and intensity-model-based methods, are introduced due to their smooth reconstruction. However, both suffer from limitations. With the shape-model-based method, only the boundary profile is considered, leading to the loss of valid intensity information. For the intensity-based-method, the computation speed is slow because it needs to calculate the intensity distribution in each iteration. To address these issues, we propose a new reconstruction method using X-ray images and a specimen’s CT data. Specifically, the CT data provides both the shape mesh and the intensity model of the vertebra. Intensity model is used to generate the deformation field from X-ray images, while the shape model is used to generate the patient specific model by applying the calculated deformation field.Experiments on the public synthetic dataset and clinical dataset show that the average reconstruction errors are 1.1 mm and1.2 mm, separately. The average reconstruction time is 3 minutes. | Longwei Fang Zuowei Wang Zhiqiang Chen Fengzeng Jian Shuo Li Huiguang He | 2020 | IEEE/CAA Journal of Automatica Sinica2020，7，4： | 3 |
| 9 | Influence of amplified spontaneous emission and fluorescence of β-carotene on stimulated Raman scattering of carbon disulfide显示文摘β-carotene with double fluorescence characteristics and large third-order optical nonlinearities,which is dissolved in the carbon disulfide(CS2) as the core medium of a liquid core optical fiber(LCOF),is applied in the study of the CS2 stimulated Raman scattering(SRS). The results of this study show that when the concentrations of solution are more than 3.72×10-7 mol/L,the amplified spontaneous emis-sion(ASE) of β-carotene is the main factor influencing the threshold and intensity of Stokes lines; when the concentrations of solution are lower than 3.72×10-7 mol/L,the ASE disappears and the fluorescence plays the key role:The high-order Stokes lines may be observed at very low input-laser power,and the Stokes thresholds decrease as the solution concentration increases. The result may be widely used in the study of broadband stimulated radiation laser and seeding laser. | MEN ZhiWei SUN XiuPing FANG WenHui LI ZuoWei CAO Biao GAO ShuQin LU GuoHui | 2009 | Science China(Physics,Mechanics & Astronomy)2009，52，4： | 3 |
| 10 | Clinical characteristics and clinicopathological correlations of bilateral breast cancer in China:A multicenter study from Chinese Society of Breast Surgery(CSBrS-006)显示文摘Objective:To investigate the clinical characteristics and clinicopathological correlations of bilateral breast cancer(BBC)in China.Methods:Data of 440 patients diagnosed with BBC in 2018 were collected from 33 centers of the Chinese Society of Breast Surgery.Demographic characteristics,bilateral tumor characteristics,and comprehensive treatment data were obtained.Correlations between the clinicopathological characteristics of bilateral tumors were analyzed.Results:The proportion of BBC was 0.22%-3.08%.A total of 33(7.5%)patients had a family history of malignant tumors,304(69.1%)patients had synchronous BBC.Only 1(0.2%)patient was male.More than half of all patients received concurrent or asynchronous endocrine/chemotherapy,32.5%of all human epidermal growth factor receptor 2(HER2)-positive patients received HER2-targeted therapy,and approximately 21.6%of all patients received radiotherapy.The most common pathological cancer type was invasive ductal cancer(>60%).Approximately 70%of all patients had bilateral hormone receptor(HR)-positive tumors and presented with a single breast mass.Significant correlations were found with pathological type,histological grade,locations of tumor,molecular subtype,Ki-67 index,tumor site and size of bilateral tumors.Results of the subgroup analysis showed more clinicopathological characteristics when synchronous BBC was compared with metachronous BBC.Conclusions:In China,the clinicopathological characteristics of bilateral tumors showed significant correlations,and more significant clinicopathological correlations were observed when synchronous BBC was compared with metachronous BBC. | Xuelu Li Yitong Wang Bo Pan Man Li Jiyue Gao Yi Zhao Zuowei Zhao Chinese Society of Breast Surgery | 2021 | Chinese Journal of Cancer Research2021，33，1： | 2 |

| 13 | Physicochemical properties and biological activities of polysaccharides from the peel of Dioscorea opposita Thunb.extracted by four different methods显示文摘Polysaccharides are the important biologically active components found in the peel of Dioscorea opposita Thunb.(DTTP).The influences of 4 extraction methods,namely hot water extraction(W),acidic extraction(HA),hot-compressed water extraction(HCW)and enzyme-assisted extraction(EAE),on the yields,physicochemical properties,hypoglycemic and antioxidant activities of polysaccharides from DTTP were studied and compared.Among these DTTP polysaccharides,DTTP-HA was outstanding in several respects.DTTP-HA was the most water soluble;it had the highest total carbohydrate content(85.08%),the highest uronic acid(13.20%)and the highest thermal stability.DTTP-HA and DTTP-W possessed a triple-helix structure.These 4 kinds of polysaccharides have the same types of monosaccharides,but in different molar percentages.Extraction method had a significant impact on the microstructures of the extracted polysaccharides.DTT-HA exhibited irregular structure with many holes.Among the 4 extracted methods,the DTTP-HA and DTTP-W initially exhibited higher hypoglycemic and antioxidant activities.The better bioactivities of DTTP-HA may be related to the above factors.The findings indicated that acid extraction is an effective method to extract polysaccharides with high biological activities from DTTP. | Zuowei Zhao Li Wang Yuan Ruan Chunnan Wen Menghuan Ge Yanyan Qian Bingji Ma | 2023 | Food Science and Human Wellness2023，12，1： | 1 |
