| 1 | Double-stream-pouring technique for production of gradient materials by continuous casting显示文摘A novel method for producing gradient materials by continuous casting is introduced. By using many-stream-pouring technique, samples with gradient distribution of alloy composition along the cross section have been prepared. The main difference of this method from the conventional continuous casting is the pouring system equipped with two sets of tundishes for liquid metals of different alloy compositions. Special consideration is given to the promotion and control of the cross-sectional mass transport. The steady heat transfer and mass flow ensure a partial mixing of two metals and yield a continously varying composition distribution. By adjusting the processing parameters, composition profile with different shapes can be achieved. First experiments have been carried out in Al-Si system and Al-Cu system for three series of Al/AlSi, AlSi/Al and AlCu/Al. It is shown that the alloy composition, the microstructure and the mechanical property change smoothly from the centre to the surface of the samples. This simple and practical method is potential for mass prodution of 'structural gradient materials' and may offer a new way for alloy design. | Zhang Weiwen Zhu Cangshan Wei Xingzhao Meng Jilong Yuan Shugui Yu Ge | 1998 | Chinese Science Bulletin1998，43，11： | 16 |
| 2 | Photodegradation of Norfloxacin in aqueous solution containing algae显示文摘Photodegradation of Norfloxacin in aqueous solution containing algae under a medium pressure mercury lamp(15 W,λ max = 365 nm) was investigated.Results indicated that the photodegradation of Norfloxacin could be induced by the algae in the heterogeneous algaewater systems.The photodegradation rate of Norfloxacin increased with increasing algae concentration,and was greatly influenced by the temperature and pH of solution.Meanwhile,the cooperation action of algae and Fe(III),and the ultrasound were beneficial to photodegradation of Norfloxacin.The degradation kinetics of Norfloxacin was found to follow the pseudo zero-order reaction in the suspension of algae.In addition,we discussed the photodegradation mechanism of Norfloxacin in the suspension of algae.This work will be helpful for understanding the photochemical degradation of antibiotics in aqueous environment in the presence of algae,for providing a new method to deal with antibiotics pollution. | Junwei Zhang Dafang Fu Jilong Wu | 2012 | Journal of Environmental Sciences2012，24，4： | 10 |
| 3 | Long-term effects of gravel―sand mulch on soil organic carbon and nitrogen in the Loess Plateau of northwestern China显示文摘Gravel–sand mulch has been used for centuries to conserve water in the Loess Plateau of northwestern China. In this study, we assessed the influence of long-term(1996–2012) gravel–sand mulching of cultivated soils on total organic carbon(TOC), light fraction organic carbon(LFOC), microbial biomass carbon(MBC), total organic nitrogen(TON), particulate organic carbon(POC), mineral-associated organic carbon(MOC), permanganate-oxidizable carbon(KMn O4-C), and non-KMn O4-C at 0–60 cm depths. Mulching durations were 7, 11 and 16 years, with a non-mulched control. Compared to the control, there was no significant and consistently positive effect of the mulch on TOC, POC, MOC, KMn O4-C and non-KMn O4-C before 11 years of mulching, and these organic C fractions generally decreased significantly by 16 years. LFOC, TON and MBC to at a 0–20 cm depth increased with increasing mulching duration until 11 years, and then these fractions decreased significantly between 11 and 16 years, reaching values comparable to or lower than those in the control. KMn O4-C was most strongly correlated with the labile soil C fractions. Our findings suggest that although gravel–sand mulch may conserve soil moisture, it may also lead to long-term decreases in labile soil organic C fractions and total organic N in the study area. The addition of manure or composted manure would be a good choice to reverse the soil deterioration that occurs after 11 years by increasing the inputs of organic matter. | Yang QIU ZhongKui XIE YaJun WANG Sukhdev S MALHI JiLong REN | 2015 | Journal of Arid Land2015，7，1： | 7 |
| 4 | DRAGON-Lab―Next generation internet technology experiment platform显示文摘Testbed technology is very important in the development of the Internet. Similar to the present internet,next generation internet also starts from testbed. There are two kinds of testbeds,testbed networks like CNGI-CERNET2,Internet2,Geant;testbed systems like PlanetLab,NS2. DRAGON-Lab can be viewed as both testbed network and testbed system. DRAGON-Lab is an independent AS(autonomous system) and connected to multiple real networks. On the other hand,DRAGON-Lab integrates many resources of its own,partners' and internet's,so as to provide open service. DRAGON-Lab has a large scale,provides open service,supports remote visualized experiments and programmable experiments. More details will be introduced in this paper. | WANG JiLong LI ZhongHui LV GuoHan JIANG CaiPing LI Xing ZHANG QianLi | 2008 | Science in China(Series F)2008，51，11： | 6 |
| 5 | DNA degradation within mouse brain and dental pulp cells 72 hours postmortem显示文摘In this study, we sought to elucidate the process of DNA degradation in brain and dental pulp cells of mice, within postmortem 0-72 hours, by using the single cell gel electrophoresis assay and professional comet image analysis and processing techniques. The frequency of comet-like cells, the percentage of tail DNA, tail length, tail moment, Olive moment and tail area increased in tandem with increasing postmortem interval. In contrast, the head radius, the percentage of head DNA and head area showed a decreasing trend. Linear regression analysis revealed a high correlation between these parameters and the postmortem interval. The findings suggest that the single cell gel electrophoresis assay is a quick and sensitive method to detect DNA degradation in brain and dental pulp cells, providing an objective and accurate new way to estimate postmortem interval. | Jilong Zheng Xiaona Li Di Shan Han Zhang Dawei Guan | 2012 | Neural Regeneration Research2012，7，4： | 5 |
| 6 | Roles of low?density lipoproteinreceptor?related protein 1 in tumors显示文摘Low-density lipoprotein receptor-related protein 1(LRP1,also known as CD91),a multifunctional endocytic and cell signaling receptor,is widely expressed on the surface of multiple cell types such as hepatocytes,fibroblasts,neurons,astrocytes,macrophages,smooth muscle cells,and malignant cells.Emerging in vitro and in vivo evidence demonstrates that LRP1 is critically involved in many processes that drive tumorigenesis and tumor progression.For example,LRP1 not only promotes tumor cell migration and invasion by regulating matrix metalloproteinase(MMP)-2and MMP-9 expression and functions but also inhibits cell apoptosis by regulating the insulin receptor,the serine/threonine protein kinase signaling pathway,and the expression of Caspase-3.LRPI-mediated phosphorylation of the extracellular signal-regulated kinase pathway and c-jun N-terminal kinase are also involved in tumor cell proliferation and invasion.In addition,LRP1 has been shown to be down-regulated by microRNA-205 and methylation of LRP1CpG islands.Furthermore,a novel fusion gene,LRP1-SNRNP25,promotes osteosarcoma cell invasion and migration.Only by understanding the mechanisms of these effects can we develop novel diagnostic and therapeutic strategies for cancers mediated by LRP1. | Peipei Xing Zhichao Liao Zhiwu Ren Jun Zhao Fengju Song Guowen Wang Kexin Chen Jilong Yang | 2016 | Chinese Journal of Cancer2016，35，1： | 4 |
| 7 | Domesticated cynomolgus monkey embryonic stem cells allow the generation of neonatal interspecies chimeric pigs显示文摘Blastocyst complementation by pluripotent stem cell(PSC)injection is believed to be the most promising method to generate xenogeneic organs.However,ethical issues prevent the study of human chimeras in the late embryonic stage of development.Primate embryonic stem cells(ESCs),which have similar pluripotency to human ESCs,are a good model for studying interspecies chimerism and organ generation.However,whether primate ESCs can be used in xenogenous grafts remains unclear.In this study,we evaluated the chimeric ability of cynomolgus monkey(Macaca fascicularis)ESCs(cmESCs)in pigs,which are excellent hosts because of their many similarities to humans.We report an optimized culture medium that enhanced the anti-apoptotic ability of cmESCs and improved the development of chimeric embryos,in which domesticated cmESCs(D-ESCs)injected into pig blastocysts differentiated into cells of all three germ layers.In addition,we obtained two neonatal interspecies chimeras,in which we observed tissue-specific D-ESC differentiation.Taken together,the results demonstrate the capability of D-ESCs to integrate and differentiate into functional cells in a porcine model,with a chimeric ratio of 0.001-0.0001 in different neonate tissues.We believe this work will facilitate future developments in xenogeneic organogenesis,bringing us one step closer to producing tissue-specific functional cells and organs in a large animal model through interspecies blastocyst complementation. | Rui Fu Dawei Yu Jilong Ren Chongyang Li Jing Wang Guihai Feng Xuepeng Wang Haifeng Wan Tianda Li Libin Wang Ying Zhang Tang Hai Wei Li Qi Zhou | 2020 | Protein & Cell2020，11，2： | 4 |
| 8 | Terrain relief periods of loess landforms based on terrain profiles of the Loess Plateau in northern Shaanxi Province,China显示文摘The Loess Plateau is densely covered by numerous types of gullies which represent different soil erosion intensities.Therefore,research on topographic variation features of the loess gullies is of great significance to environmental protection and ecological management.Using a5 m digital elevation model and data from a national geographic database,this paper studies different topographical areas of the Loess Plateau,including Shenmu,Suide,Yanchuan,Ganquan,Yijun,and Chunhua,to derive representative gully terrain profile data of the sampled areas.First,the profile data are standardized in MATLAB and then decomposed using the ensemble empirical mode decomposition method.Then,a significance test is performed on the results;the test confidence is 95% to 99%.The most reliable decomposition component is then used to calculate the relief period and size of the gullies.The results showed that relief periods of the Chunhua,Shenmu,Yijun,Yuanchuan,Ganquan,and Suide gullies are 1110.14 m,1096.85 m,1002.49 m,523.48 m,498.12 m,and 270.83 m,respectively.In terms of gully size,the loess landforms are sorted as loess fragmented tableland,aeolian and dune,loess tableland,loess ridge,loess hill and loess ridge,and loess hill,in descending order.Taken together,the gully terrain features of the sample areas and the results of the study are approximately consistent with the actual terrain profiles.Thus,we conclude that ensemble empirical mode decomposition is a reliable method for the study of the relief and topography of loess gullies. | Jianjun CAO Guoan TANG Xuan FANG Jilong LI Yongjuan LIU Yiting ZHANG Ying ZHU Fayuan LI | 2019 | Frontiers of Earth Science2019，13，2： | 4 |
| 9 | Toxoplasma gondii GRA15II effector-induced M1 cells ameliorate liver fibrosis in mice infected with Schistosomiasis japonica显示文摘Recent studies indicated that type II Toxoplasma gondii(Tg)GRA15II favored the generation of classically activated macrophages(M1),whereas type I/III TgROP16I/III promoted the polarization of alternatively activated macrophages(M2).A number of studies have demonstrated that M2 cells are involved in the pathogenesis of the liver fibrogenesis caused by Schistosoma japonicum.The purpose of the present study was to explore the inhibitory effect of Toxoplasma-derived TgGRA15II on mouse hepatic fibrosis with schistosomiasis.The gra15II and rop16I/III genes were amplified from strains T.gondii PRU and Chinese 1 Wh3,respectively.Lentiviral vectors containing the gra15II or rop16I/III plasmid were constructed and used to infect the RAW264.7 cell line.The polarization of the transfected cells was evaluated,followed by co-culture of the biased macrophages with mouse hepatic stellate JS1 cells.Then,mice were injected with GRA15II-driven macrophages via the tail vein and infected with S.japonicum cercariae.TgGRA15II induced a M1-biased response,whereas TgROP16I/III drove the macrophages to a M2-like phenotype.The in vitro experiments indicated that JS1 cell proliferation and collagen synthesis were decreased following co-culture with TgGRA15II-activated macrophages.Furthermore,mice inoculated with TgGRA15II-biased macrophages displayed a notable alleviation of collagen deposition and granuloma formation in their liver tissues.Our results suggest that TgGRA15II-induced M1 cells may dampen the M2 dominant pathogenesis of hepatic fibrosis and granulomatosis.These results provide insights into the use of parasite-derived immunomodulators as potential anti-fibrosis agents and to re-balance the schistosomiasis-induced immune response. | Yuanyuan Xie Huiqin Wen Ke Yan Shushu Wang Xuesong Wang Jian Chen Yuanling Li Yuanhong Xu Zhengrong Zhong Jilong Shen Deyong Chu | 2018 | Cellular & Molecular Immunology2018，15，2： | 4 |
| 10 | Controlled mechanical assembly of complex 3D mesostructures and strain sensors by tensile buckling显示文摘Recent research establishes methods of controlled mechanical assembly as versatile routes to three-dimensional(3D)mesostructures from patterned 2D films,with demonstrated applicability to a broad range of materials(e.g.,semiconductors,polymers,metals,and their combinations)and length scales(e.g.,from sub-microscale to centimeter scale).Previously reported schemes use pre-stretched elastomeric substrates as assembly platforms to induce compressive buckling of 2D precursor structures,thereby enabling their controlled transformation into 3D architectures.Here,we introduce tensile buckling as a different,complementary strategy that bypasses the need for a pre-stretched platform,thereby simplifying the assembly process and opening routes to additional classes of 3D geometries unobtainable with compressive buckling.A few basic principles in mechanics serve as guidelines for the design of 2D precursor structures that achieve large out-of-plane motions and associated 3D transformations due to tensile buckling.Experimental and computational studies of nearly 20 examples demonstrate the utility of this approach in the assembly of complex 3D mesostructures with characteristic dimensions from micron to millimeter scales.The results also establish the use of nonlinear mechanics modeling as a mechanism for designing systems that yield desired 3D geometries.A strain sensor that offers visible readout and large detectable strain range through a collection of mechanically triggered electrical switches and LEDs serves as an application example. | Xiaogang Guo Xueju Wang Dapeng Ou Jilong Ye Wenbo Pang Yonggang Huang John A.Rogers Yihui Zhang | 2018 | npj Flexible Electronics2018，2，1： | 4 |
| 11 | Interface transferring mechanism and error modification of embedded FBG strain sensors显示文摘As the strain sensing element of a structural health monitoring,the study and the application of the fibre-optic bragg grating(FBG)have been widely accepted.The accuracy of the FBG sensor is highly dependent on the physical and the mechanical properties of the strain interface transferring characteristics among the layers of bare optical fibre,protective coating,adhesive layer and host material.In this paper,firstly,the general expression of the multilayer interface strain transferring mechanism is derived.Secondly,based on the defined average strain,the error-modified equation of the FBG sensor is obtained.Finally,in the light of the embedded tube-packaged FBG and the fibre reinforced polymer-optical fibre bragg grating(FRP-OFBG)strain sensors,developed in the Harbin Institute of Technology(HIT),the corresponding strain transferring laws have been studied,and the corresponding error modification coefficients have also been given,which are validated by experiments.The research results provide theories for the development and application of the embedded FBG sensors. | ZHOU Zhi LI Jilong OU Jinping | 2007 | Frontiers of Electrical and Electronic Engineering in China2007，2，1： | 3 |
| 12 | Effect of silicon precursor on silicon incorporation in SAPO-11 and their catalytic performance for hydroisomerization of n-octane on Pt-based catalysts显示文摘SAPO-11 molecular sieves were synthesized using silica sol, hydrophilic fumed silica, and tetraethyl orthosilicate(TEOS) as silicon precursors. Their physicochemical properties were characterized using XRD,SEM, nitrogen adsorption-desorption, Py-IR, NH_3-TPD, EDS, and ^(27)Al,^(31)P,^(29)Si MAS NMR techniques. The catalytic performance was assessed in the hydroisomerization of n-octane. The results showed that the silicon precursors influenced the physicochemical properties and catalytic performance of SAPO-11. SAPO-11 synthesized using hydrophilic fumed silica as silicon precursor showed higher silicon distribution and had more medium acid sites. SAPO-11 synthesized using TEOS as silicon precursor had more silicon content, but more silicon islands formed in its framework. The depolymerization of silicon precursors might affect the silicon content and distribution in SAPO-11. In the hydroisomerization of n-octane, the catalytic activity strongly depended on the number of medium acid sites instead of the number of total acid sites.SAPO-11 synthesized using hydrophilic fumed silica as silicon precursor exhibited higher catalytic activity than the other samples because it has more medium acid sites. | Zhichao Yang Jilong Li Yunqi Liu Chenguang Liu | 2017 | Journal of Energy Chemistry2017，26，4： | 3 |
| 13 | Origin and evolution of ore-forming fluid for the Gaosongshan gold deposit, Lesser Xing’an Range:Evidence from fluid inclusions,H-O-S-Pb isotopes显示文摘Epithermal gold deposits are typical precious metal deposits related to volcanic and subvolcanic magmatism.Due to the lack of direct geological and petrographic evidences,the origin of the ore-forming fluid is deduced from the spatial diagenesis-mineralization relationship,chronological data,physicochemical characteristics of mineral fluid inclusions,mineral or rock elements and isotopic geochemical characteristics.By objectively examining this scientific problem via a geological field survey and petrographic analysis of the Gaosongshan epithermal gold deposit,we recently discovered and verified the following points:(1) Pyrite-bearing spherical quartz aggregates (PSQA) occur in the rhyolitic porphyry;(2) the mineralization is structurally dominated by WNW- and ENE-trending systems and occurs mostly in hydrothermal breccias and pyrite-quartz veins,and the ore types are mainly hematite-crusted quartz,hydrothermal breccia,massive pyrite-quartz,etc.;(3) the alteration types consist of prevalent silicification,sericitization,propylitization and carbonation,with local adularization and illitization.The ore minerals are mainly pyrite,primary hematite,native gold,and electrum,with lesser amounts of chalcopyrite,magnetite,sphalerite,and galena,indicating a characteristic epithermal low-sulfidation deposit.The ore-forming fluid may have been primarily derived from magmatic fluid exsolved from a crystallizing rhyolitic porphyry magma.Further zircon U-Pb geochronology,fluid inclusion,physicochemical and isotopic geochemical analyses revealed that (1) rhyolitic porphyry magmatism occurred at 104.6 ± 1.0 Ma,whereas the crystallization of the PSQA occurred at 100.8 ± 2.1 Ma;(2) the hydrothermal fluid of the pre-ore stage was an exsolved CO2-bearing H2O-NaCl magmatic fluid that produced inclusions mainly composed of pure vapor (PV),vapor-rich (WV) and liquid-rich (WL) inclusions with a small number of melt-(M) and solid-bearing (S) inclusions;mineralization-stage quartz contains WL and rare PV,WV and pure liquid (PL) inclusions characterized by the H2O-NaCl system with low formation temperatures and low salinities;(3) the characteristics of hydrogen,oxygen,sulfur,and lead isotopes and those of rare earth elements (REEs) provide insight into the affinity between PSQA and orebodies resulting from juvenile crust or enriched mantle.Combined with previous research on the mineralogenetic epoch (99.32 ± 0.01 Ma),we further confirm that the mineralization of the deposit occurred in the late Early Cretaceous,which coincides with the extension of the continental margin induced by subduction of the Pacific Plate beneath the Eurasian Plate.The formation of the ore deposit was proceeded by a series of magmatic and hydrothermal events,including melting of enriched juvenile crust,upwelling,the eruption and emplacement of the rhyolitic magma,the exsolution and accumulation of magmatic hydrothermal fluid,decompression,the cooling and immiscibility/boiling of the fluid,and mixing of the magmatic fluid with meteoric water,in association with water-rock interaction. | Yang Liu Jinggui Sun Jilong Han Liang Ren Alei Gu Keqiang Zhao Changshen Wang | 2019 | Geoscience Frontiers2019，10，5： | 3 |
| 14 | Differences and Links between the East Asian and South Asian Summer Monsoon Systems:Characteristics and Variability显示文摘This paper analyzes the differences in the characteristics and spatio–temporal variabilities of summertime rainfall and water vapor transport between the East Asian summer monsoon(EASM) and South Asian summer monsoon(SASM) systems. The results show obvious differences in summertime rainfall characteristics between these two monsoon systems. The summertime rainfall cloud systems of the EASM show a mixed stratiform and cumulus cloud system, while cumulus cloud dominates the SASM. These differences may be caused by differences in the vertical shear of zonal and meridional circulations and the convergence of water vapor transport fluxes. Moreover, the leading modes of the two systems' summertime rainfall anomalies also differ in terms of their spatiotemporal features on the interannual and interdecadal timescales. Nevertheless, several close links with respect to the spatiotemporal variabilities of summertime rainfall and water vapor transport exist between the two monsoon systems. The first modes of summertime rainfall in the SASM and EASM regions reveal a significant negative correlation on the interannual and the interdecadal timescales. This close relationship may be linked by a meridional teleconnection in the regressed summertime rainfall anomalies from India to North China through the southeastern part over the Tibetan Plateau, which we refer to as the South Asia/East Asia teleconnection pattern of Asian summer monsoon rainfall. The authors wish to dedicate this paper to Prof. Duzheng YE, and commemorate his 100 thanniversary and his great contributions to the development of atmospheric dynamics. | Ronghui HUANG Yong LIU Zhencai DU Jilong CHEN Jingliang HUANGFU | 2017 | Advances in Atmospheric Sciences2017，34，10： | 3 |
| 15 | Estimation of Postmortem Interval Using the Radiological Techniques,Computed Tomography:A Pilot Study显示文摘Estimation of postmortem interval(PMI)has been an important and difficult subject in the forensic study.It is a primary task of forensic work,and it can help guide the work in field investigation.With the development of computed tomography(CT)technology,CT imaging techniques are now being more frequently applied to the field of forensic medicine.This study used CT imaging techniques to observe area changes in different tissues and organs of rabbits after death and the changing pattern of the average CT values in the organs.The study analyzed the relationship between the CT values of different organs and PMI with the imaging software Max Viewer and obtained multiparameter nonlinear regression equation of the different organs,and the study provided an objective and accurate method and reference information for the estimation of PMI in the forensic medicine.In forensic science,PMI refers to the time interval between the discovery or inspection of corpse and the time of death.CT,magnetic resonance imaging,and other imaging techniques have become important means of clinical examinations over the years.Although some scholars in our country have used modem radiological techniques in various fields of forensic science,such as estimation of injury time,personal identification of bodies,analysis of the cause of death,determination of the causes of injury,and identification of the foreign substances of bodies,there are only a few studies on the estimation of time of death.We detected the process of subtle changes in adult rabbits after death,the shape and size of tissues and organs,and the relationship between adjacent organs in three-dimensional space in an efiort to develop new method for the estimation of PMI.The bodies of the dead rabbits were stored at 20℃ room temperature,sealed condition,and prevented exposure to flesh flies.The dead rabbits were randomly divided into comparison group and experimental group.The whole-body CT scans were performed on the experimental group of rabbits at different PMIs.NeuViz dual-slice spiral CT scanner(made by Neusoft Medical in China,2 mm×10 mm high-speed rare earth ceramic detector)is a 360°scan that could obtain two images,capable of providing a wide range of high-speed continuous spiral scan.Max Viewer(Version:1.0.0131,Neusoft,Shenyang,China)is a CT image viewing software developed by Neusoft Medical.The software can be used to view and process images in various common methods and to measure a number of parameters,such as length,area,angle,and CT values.Statistical analysis was performed using SPSS1 Statistics 19.0(SPSS,Inc.,Chicago,IL,USA).AP<0.05 was considered statistically significant.We obtained the binomial regression equation of the CT values and the related coefficient(R^(2)).In the future,we suggests that comprehensive analyses of various indicators of different organs could establish a diversified pattern to remedy the deficiencies and make the study of PMI estimation more scientific and enhance the operability. | Jiulin Wang Jilong Zheng Jiaxin Zhang Shoutao Ni Biao Zhang | 2017 | Journal of Forensic Science and Medicine2017，3，1： | 3 |
| 16 | Landform Planation Index Extracted from DEMs: A Case Study in Ordos Platform of China显示文摘Planation surface, a surface that is almost flat, is a kind of low-relief landforms. Planation surface is the consequence of the denudation and planation processes under a tectonic stable condition. The quantitative expression of the characteristics of planation surface plays a key role in reconstructing and describing the evolutionary process of landforms. In this study, Landform Planation Index(LPI), a new terrain derivative, was proposed to quantify the characteristics of planation surface. The LPIs were calculated based on the summit surfaces formed according to the clustering results of peaks. Ten typical areas in the Ordos Platform located in the central part of the Loess Plateau of China are chosen as the test areas for investigating their planation characteristics with the LPI. The experimental results indicate that the LPI can be effectively used to quantify the characteristics of planation surfaces. In addition, the LPI can be further used to depict the patterns of spatial differentiation in the Ordos Platform. Although the present Ordos Platform area is full of the high-density gullies, its planation characteristics is found to be well preserved. Furthermore, the characteristics of the planation surfaces can also reflect the original morphology of the Ordos Platform before the loess dusts deposition process evolved in this area. The statistical results of the LPI show that there is a gradually increasing tendency along with the increasing of slope gradient of summit surface. It indicates that the characteristics of planation surfaces vary among test areas with different landforms. These findings help to deepen the understanding of planation characteristics of the loess landform and its underlying paleotopography. Results of this study can be also served as an important theoretical reference value for revealing the evolutionary process of loess landform. | QIAN Yeqing XIONG Liyang LI Jilong TANG Guoan | 2016 | Chinese Geographical Science2016，26，3： | 3 |
| 17 | Chondroblastoma in the long bone diaphysis:a report of two cases with literature review显示文摘To investigate the clinical characteristics of chondroblastoma with an emphasis on lesions located in the long bone diaphysis,we reviewed the clinical data of 7 patients with histologically proven chondroblastoma treated in Tianjin Medical University Cancer Hospital and Fudan University Cancer Hospital between January 1995 and May 2009.There were two rare cases of chondroblastoma in the long bone diaphysis.One patient with a lesion in the tibial diaphysis underwent intralesional curettage and bone grafting,and the postoperative bone function was measured as excellent according to the Enneking scoring system.The patient was still alive upon follow-up at 60 months.The other patient with a lesion in the humeral diaphysis underwent resection,and the postoperative bone function was excellent at 48 months,at which there was no evidence of recurrence or metastasis.Thus,except for the distinctive site of the long bone diaphysis,which made diagnosis difficult,the patients' ages,symptoms,X-ray and CT images,treatment,and prognosis were in accordance with typical lesions in the epiphysis and metaphysis.The diagnosis of chondroblastoma in the long bone diaphysis significantly depends on histopathologic characteristics. | Jilong Yang Wei Tian Xiongzeng Zhu Jian Wang | 2012 | Chinese Journal of Cancer2012，31，5： | 3 |
| 18 | Dynamic and Seismic Property Experiments of High Damping Concrete and Its Frame Models显示文摘The loss tangent and storage modulus of cement mortar containing treated silica fume and styrene-acrylic are measured.Shaking table tests on three groups of 1/4 models of high damping concrete frames are conducted to compare the effects of reducing vibration.A relationship between the viscosity coefficient of high damping concrete and the damping coefficient of structure is established by analyzing dynamic parameters like damping ratio and frequency,and comparing responses of relative displacement and absolute acceleration. Surface treatment of silica fume and styrene-acrylic emulsion prior to incorporation in a cement mortar increases the loss tangent of the resulting composite by 40-400% as compared to the cement mortar without any admixtures,and the damping ratio of the reinforced concrete is raised by 7%-9%.In addition,a theoretical method of determining the viscosity coefficient of the material on the basis of shaking table test results is put forward. | 欧进萍 刘铁军 LI Jilong | 2008 | Journal of Wuhan University of Technology(Materials Science)2008，23，1： | 3 |
| 19 | The prognostic significance of non-sentinel lymph node metastasis in cutaneous and acral melanoma patients—A multicenter retrospective study显示文摘Background:Whether non-sentinel lymph node(SLN)-positive melanoma patients can benefit from completion lymph node dissection(CLND)is still unclear.The current study was performed to identify the prognostic role of nonSLN status in SLN-positive melanoma and to investigate the predictive factors of non-SLN metastasis in acral and cutaneous melanoma patients.Methods:The records of 328 SLN-positive melanoma patients who underwent radical surgery at four cancer centers from September 2009 to August 2017 were reviewed.Clinicopathological data including age,gender,Clark level,Breslow index,ulceration,the number of positive SLNs,non-SLN status,and adjuvant therapy were included for survival analyses.Patients were followed up until death or June 30,2019.Multivariable logistic regression modeling was performed to identify factors associated with non-SLN positivity.Log-rank analysis and Cox regression analysis were used to identify the prognostic factors for disease-free survival(DFS)and overall survival(OS).Results:Among all enrolled patients,220(67.1%)had acral melanoma and 108(32.9%)had cutaneous melanoma.The 5-year DFS and OS rate of the entire cohort was 31.5%and 54.1%,respectively.More than 1 positive SLNs were found in 123(37.5%)patients.Positive non-SLNs were found in 99(30.2%)patients.Patients with positive non-SLNs had significantly worse DFS and OS(log-rank P<0.001).Non-SLN status(P=0.003),number of positive SLNs(P=0.016),and adjuvant therapy(P=0.025)were independent prognostic factors for DFS,while non-SLN status(P=0.002),the Breslow index(P=0.027),Clark level(P=0.006),ulceration(P=0.004),number of positive SLNs(P=0.001),and adjuvant therapy(P=0.007)were independent prognostic factors for OS.The Breslow index(P=0.020),Clark level(P=0.012),and number of positive SLNs(P=0.031)were independently related to positive non-SLNs and could be used to develop more personalized surgical strategy.Conclusions:Non-SLN-positive melanoma patients had worse DFS and OS even after immediate CLND than those with non-SLN-negative melanoma.The Breslow index,Clark level,and number of positive SLNs were independent predictive factors for non-SLN status. | Wei Sun Yu Xu JiLong Yang ZhiChao Liao Tao Li Kai Huang Poulam Patel WangJun Yan Yong Chen | 2020 | Cancer Communications2020，40，11： | 2 |
| 20 | Routing Loop Audit Mechanism Based on SDN显示文摘Routing loops can cause packet loss and long delay problems in the traditional network. Even in future networks – Software-Defined Networks, with loop-free implementation mechanism, it still suffers loop problems. In this paper, we propose an architecture to solve the loop problem in SDN. Unlike the existing passive routing loop detection algorithm, this algorithm processes based on the SDN loop-free characteristic, by auditing third-party network forwarding rules’ modification requests to avoids loop generation, thus avoid the network loop problems. Testbed is built to simulate our proposed algorithm. The evaluation shows that the loop audit algorithm proposed in this paper has better performance in extra spatial utilization and smaller number of extra interactions between SDN controller and switches. | Tao Yu Yuchen Zhang Diyue Chen Hongyan Cui Jilong Wang | 2019 | China Communications2019，16，7： | 2 |
