| 1 | Immunohistochemical assessment of angiogenesis in hepatocellular carcinoma and surrounding cirrhotic liver tissues显示文摘AIM: To investigate whether vascular endothelial growth factor (VEGF) was over-expressed in hepatocellular carcinoma (HCC) or in surrounding cirrhotic liver tissues.METHODS: Immunohistochemistry was performed to investigate the expression of VEGF proteins in HCC tissues from 105 consecutive patients undergoing curative resection for HCC. The immunostaining results and related clinicopathologic materials were analyzed with statistical methods. Kaplan-Meier method was used to calculate survival curves, and Log-rank test was performed to compare differences in survival rates of the patients with positive HCC staining and negative VEGF.RESULTS: VEGF-positive expression was found in 72 of105 HCC patients (68.6%). Capsular infiltration (P= 0.005),vascular invasion (P = 0.035) and intrahepatic metastasis(P=0.008) were observed more frequently in patients with VEGF-positive expression than in those with VEGFnegative expression. Kaplan-Meier curves showed that VEGF-positive expression was associated with a shorter overall survival (P = 0.014). VEGF-positive expression was found in 47 of tissues 68 HCC (69.1%), and VEGF-positive expression was found in 54 of 68 surrounding cirrhotic liver tissues (79.4%). VEGF-positive expression was significantly higher in surrounding cirrhotic liver tissues than in HCC (P= 0.017).CONCLUSION: VEGF may play an important role in the angiogenesis and prognosis of HCC, as well as in the angiogenesis of liver cirrhosis. | GeertuDeli Can-HaoJin RongMu SongYang YueLiang DeChen MasatoshiMakuuchi | 2005 | World Journal of Gastroenterology2005，11，7： | 19 |

| 3 | Initial corrosion behavior and mechanism of 7B04 aluminum alloy under acid immersion and salt spray environments显示文摘The initial corrosion behavior and mechanism of 7B04 aluminum alloy under acid immersion and salt spray environments(pH=3.5)are studied by Scanning Electron Microscope(SEM),optical microscope,Fourier Transform Infrared Spectroscopy(FT-IR),X-Ray Diffraction(XRD),potentiodynamic polarization,Electrochemical Impedance Spectroscopy(EIS),and Scanning Kelvin Probe(SKP).The results show that pitting corrosion occurs at the initial corrosion stage,and the potential difference between the second phase particles is the main cause of pitting.Pitting pits on different locations gradually expand and coalesce with the proceeding of corrosion.The main components of corrosion products are Al_(2)O_(3),Al(OH)_(3),and AlCl_(3),and the generation rate of the corrosion product layer under the salt spray environment is larger than that under acid immersion environment.Under both environments,the Volta potential distribution first disperses and then concentrates,while the charge transfer resistance first decreases and then increases with the corrosion time.The Volta potential gradually shifts in a positive direction,indicating that corrosion products have an inhibitory effect on corrosion.After the same corrosion time,the corrosion product layer resistance and the expectation of the Volta potential of the salt spray sample are higher than those of the immersion sample.Comparatively,the corrosion current density for the salt spray sample is significantly lower than the immersion sample,which indicates that the thicker the corrosion product layer,the stronger the inhibition of corrosion reaction. | Yangguang ZHANG Yueliang CHEN Yong ZHANG Guixue BIAN Chenguang WANG Andong WANG | 2022 | Chinese Journal of Aeronautics2022，35，1： | 8 |
| 4 | Availability modeling for periodically inspection system with different lifetime and repair-time distribution显示文摘Availability is a main feature of design and operation of all engineering system. Recently,availability evaluation of periodical inspection systems with different structures is at the center of attention due to the wide application in engineering. In this paper, an analytical and probabilistic availability model for periodical inspection system is proposed by a new recursively algorithm,which can achieve limiting average availability and instantaneous availability of periodical inspection system under arbitrary lifetime and repair-time distributions. Then three application examples are presented, the systems lifetime and repair-time are respectively fellow exponential/exponential,Weibull/normal and Weibull/lognormal distribution. Finally, a Weibull/lognormal system is studied to analyze the dynamic relationship between inspection period and availability. The results indicate that the proposed approach can provide the technology support for improving system availability and determining reasonable inspection period. | Junliang LI Yueliang CHEN Yong ZHANG Hailiang HUANG | 2019 | Chinese Journal of Aeronautics2019，32，7： | 7 |
| 5 | A Storage-Driven CO_(2) EOR for a Net-Zero Emission Target显示文摘Stabilizing global climate change to within 1.5℃requires a reduction in greenhouse gas emissions,with a primary focus on carbon dioxide(CO_(2))emissions.CO_(2)flooding in oilfields has recently been recognized as an important way to reduce CO_(2)emissions by storing CO_(2)in oil reservoirs.This work proposes an advanced CO_(2)enhanced oil recovery(EOR)method-namely,storage-driven CO_(2)EOR-whose main target is to realize net-zero or even negative CO_(2)emissions by sequestrating the maximum possible amount of CO_(2)in oil reservoirs while accomplishing the maximum possible oil recovery.Here,dimethyl ether(DME)is employed as an efficient agent in assisting conventional CO_(2)EOR for oil recovery while enhancing CO_(2)sequestration in reservoirs.The results show that DME improves the solubility of CO_(2)in in situ oil,which is beneficial for the solubility trapping of CO_(2)storage;furthermore,the presence of DME inhibits the'escape'of lighter hydrocarbons from crude oil due to the CO_(2)extraction effect,which is critical for sustainable oil recovery.Sto rage-driven CO_(2)EOR is superior to conventional CO_(2)EOR in improving sweeping efficiency,especially during the late oil production period.This work demonstrates that storage-driven CO_(2)EOR exhibits higher oil-in-place(OIP)recovery than conventional CO_(2)EOR.Moreover,the amount of sequestrated CO_(2)in storage-driven CO_(2)EOR exceeds the amount of emissions from burning the produced oil;that is,the sequestrated CO_(2)offsets not only current emissions but also past CO_(2)emissions.By altering developing scenarios,such as water alternating storage-driven CO_(2)EOR,more CO_(2)sequestration and higher oil recovery can be achieved.This work demonstrates the potential utilization of DME as an efficient additive to CO_(2)for enhancing oil recovery while improving CO_(2)storage in oil reservoirs. | Yueliang Liu Zhenhua Rui | 2022 | Engineering2022，，11： | 6 |

The rise time was about 23 ns and the full width at half maximum was about 125 ns for the open-circuit photovoltaic pulse when the La0.9Sr0.1MnO3 thin film in the p-n junction was irradiated by a laser of ~20 ns pulse duration and 308 nm wavelength. The photovoltaic sensitivity was 80 mV/mJ for a 308 nm laser pulse. | HUANG Yanhong L(U) Huibin HE Meng ZHAO Kun CHEN Zhenghao CHENG Bolin ZHOU Yueliang JIN Kuijuan DAI Shouyu YANG Guozhen | 2005 | Science China(Physics,Mechanics & Astronomy)2005，48，3： | 4 |
| 7 | Effect of ambient oxygen pressure on structural, optical and electrical properties of SnO_2 thin films显示文摘Polycrystalline SnO2 thin films were deposited on sapphire substrates at 450°C under different ambient oxygen pressures by pulsed laser deposition technique. The effect of ambient oxygen pressure on the structural, optical and electri- cal properties of SnO2 thin films was studied. X-ray diffraction and Hall measurements show that increasing the ambient oxygen pressure can improve crystallization of the films and decrease resistivity of the films. A violet emission peak cen- tered at 409 nm was observed from photoluminescence measurements for SnO2 films under deposition ambient oxygen pressure above 5 Pa, which is related to the improvement of crystalline of the films. | ZHAO Songqing ZHOU Yueliang WANG Shufang ZHAO Kun HAN Peng | 2006 | Rare Metals2006，25，6： | 4 |
| 8 | A novel laser shock post-processing technique on the laser-induced damage resistance of 1ωHfO_(2)/SiO_(2)显示文摘The laser shock processing implemented by a laser-induced high-pressure plasma which propagates into the sample as a shockwave is innovatively applied as a post-processing technique on HfO_(2)/SiO_(2) multilayer coatings for the first time.The pure mechanical post-processing has provided evidence of a considerable promotion effect of the laser-induced damage threshold,which increased by a factor of about 4.6 with appropriate processing parameters.The promotion mechanism is confirmed to be the comprehensive modification of the intrinsic defects and the mechanical properties,which made the applicability of this novel post-processing technique on various types of coatings possible.Based on experiments,an interaction equation for the plasma pressure is established,which clarifies the existence of the critical pressure and provides a theoretical basis for selecting optimal processing parameters.In addition to the further clarification of the underlying damage mechanism,the laser shock post-processing provides a promising technique to realize the comprehensive and effective improvement of the laser-induced damage resistance of coatings. | Tangyang Pu Wenwen Liu Yueliang Wang Xiaoming Pan Leiqing Chen and Xiaofeng Liu | 2021 | High Power Laser Science and Engineering2021，9，2： | 4 |

| 10 | Label-free and real-time detection of antigen-antibody interactions by Oblique-incidence Reflectivity Difference(OIRD) method显示文摘We label-free and real-time detected three interaction processes of antigen-antibodies,Human Immunoglobulin G(IgG),Rabbit IgG,and Mouse IgG as the targets,and Goat Anti-human IgG,Goat Anti-rabbit IgG,and Goat Anti-mouse IgG as the probe,by the Oblique-incidence Reflectivity Difference(OIRD) method.The interaction dynamic curves of the OIRD signal,corresponding to the interaction processes of antigen-antibodies,are generated.The reaction times from beginning to equilibrium state are about 1800,900,and 1200 s for Human IgG,Rabbit IgG,and Mouse IgG,respectively.The experimental results demonstrate that the OIRD method not only can distinguish biomolecular interactions,but also can be used in real-time detection of interactions and dynamic processes of biomolecules. | HE LiPing SUN Yue DAI Jun WANG JingYi LU HuiBin WANG ShuFang JIN KuiJuan ZHOU YueLiang YANG GuoZhen | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，9： | 4 |
| 11 | Unexpected intercalation-dominated potassium storage in WS2 as a I potassium-ion battery anode显示文摘Unexpected intercalation-dominated process is observed duri ng K^+insertion in WS2 in a voltage range of 0.01-3.0 V.This is different fromthe previously reported two-dimensional(2D)transition metal dichalcogenides that undergo a conversion reaction in a low voltage rangewhen used as anodes in potassium-ion batteries.Charge/discharge processes in the K and Na cells are studied in parallel to demonstrate thedifferention storage mechanisms.The Na^+storage proceeds through intercalation and conversion reactions while the K^+storage is governedby an intercalation reaction.Owing to the reversible K^+intercalation in the van der Waals gaps,the WS2 anode exhibits a low decay rate of 0.07%per cycle,delivering a capacity of 103 mAh·g^-1 after 100 cycles at 100 mA·g^-1.It maintains 57%capacity at 800 mA·g^-1 and shows stablecyclability up to 400 cycles at 500 mA·g^-1.Kinetics study proves the facilitation of K^+transport is derived from the intercalation-dominatedmecha nism.Furthermore,the mechanismis verified by the density functional theory(DFT)calculations,showing that the progressive expansion of the interlayer space can account for the observed results. | Vuhan Wu Yang Xu Yueliang Li Pengbo Lyu Jin Wen Chenglin Zhang Min Zhou Yaoguo Fang Huaping Zhao Ute Kaiser Yong Lei | 2019 | Nano Research2019，12，12： | 3 |
| 12 | A four-gene signature-derived risk score for glioblastoma:prospects for prognostic and response predictive analyses显示文摘Objective: Glioblastoma(GBM) is the most common primary malignant brain tumor regulated by numerous genes, with poor survival outcomes and unsatisfactory response to therapy.Therefore, a robust, multi-gene signature-derived model is required to predict the prognosis and treatment response in GBM.Methods: Gene expression data of GBM from TCGA and GEO datasets were used to identify differentially expressed genes(DEGs)through DESeq2 or LIMMA methods.The DEGs were then overlapped and used for survival analysis by univariate and multivariate COX regression.Based on the gene signature of multiple survival-associated DEGs, a risk score model was established,and its prognostic and predictive role was estimated through Kaplan–Meier analysis and log-rank test.Gene set enrichment analysis(GSEA) was conducted to explore high-risk score-associated pathways.Western blot was used for protein detection.Results: Four survival-associated DEGs of GBM were identified: OSMR, HOXC10, SCARA3, and SLC39A10.The four-gene signature-derived risk score was higher in GBM than in normal brain tissues.GBM patients with a high-risk score had poor survival outcomes.The high-risk group treated with temozolomide chemotherapy or radiotherapy survived for a shorter duration than the low-risk group.GSEA showed that the high-risk score was enriched with pathways such as vasculature development and cell adhesion.Western blot confirmed that the proteins of these four genes were differentially expressed in GBM cells.Conclusions: The four-gene signature-derived risk score functions well in predicting the prognosis and treatment response in GBM and will be useful for guiding therapeutic strategies for GBM patients. | Mianfu Cao Juan Cai Ye Yuan Yu Shi Hong Wu Qing Liu Yueliang Yao Lu Chen Weiqi Dang XiangZhang Jingfang Xiao Kaidi Yang Zhicheng He Xiaohong Yao Yonghong Cui Xia Zhang Xiuwu Bian | 2019 | Cancer Biology & Medicine2019，16，3： | 2 |

| 14 | Dataflow Management in the Internet of Things: Sensing,Control, and Security显示文摘The pervasiveness of the smart Internet of Things(IoTs) enables many electric sensors and devices to be connected and generates a large amount of dataflow. Compared with traditional big data, the streaming dataflow is faced with representative challenges, such as high speed, strong variability, rough continuity, and demanding timeliness, which pose severe tests of its efficient management. In this paper, we provide an overall review of IoT dataflow management. We first analyze the key challenges faced with IoT dataflow and initially overview the related techniques in dataflow management, spanning dataflow sensing, mining, control, security, privacy protection,etc. Then, we illustrate and compare representative tools or platforms for IoT dataflow management. In addition,promising application scenarios, such as smart cities, smart transportation, and smart manufacturing, are elaborated,which will provide significant guidance for further research. The management of IoT dataflow is also an important area, which merits in-depth discussions and further study. | Dawei Wei Huansheng Ning Feifei Shi Yueliang Wan Jiabo Xu Shunkun Yang Li Zhu | 2021 | Tsinghua Science and Technology2021，26，6： | 2 |
| 15 | Colossal magnetoresistive p-n junctions of perovskite oxide La_(0.9)Sr_(0.1)MnO_3/SrNb_(0.01)Ti_(0.99)O_3显示文摘We have successfully fabricated the colossal magnetoresistive (CMR) p-n junctions of perovskite oxide La0.9Sr0.1MnO3/SrNb0.01Ti0.99O3 (LSMO/SNTO) with laser molecular beam epitaxy. The I-V characteristics of the LSMO/SNTO p-n junctions as a function of applied magnetic field (05 T) were studied between 100 and 300 K. We found that the p-n junction exhibited the CMR behavior. The CMR ratio rR/R0 (rR = RH - R0) is positive in magnetic fields below 0.13 T and at high temperature, while it displays a negative CMR near 100 K and in magnetic fields over 0.13 T. The CMR ratio values are 8% at 0.1 T and 13% at 5 T and 300 K, 40% at 0.1 T and 150 K, 10% at 0.13 T and 60% at 5 T and 100 K. The CMR behavior of the p-n junction is different from those of the LaMnO3 compound family. | L Huibin, DAI Souyu, CHEN Zhenghao, YAN Lei, ZHOU Yueliang & YANG Guozhen Laboratory of Optical Physics, Institute of Physics & Center for Condensed Matter Physics, Chinese Academy of Sciences, 100080 Beijing, China | 2003 | Chinese Science Bulletin2003，48，13： | 2 |
| 16 | Variation of the band structure in DKDP crystal excited by intense sub-picosecond laser pulses显示文摘The nonlinear absorption(NLA) properties of potassium dideuterium phosphate crystals at 515 nm under different excitation laser intensities are investigated with the Z-scan technique. Two critical intensities are highlighted: the critical intensity for exciting the NLA and the critical intensity of the multiphoton absorption mechanism transition.Experimental results indicate the existence of defect states located in the band gap, which can be manipulated by varying laser intensity. A model based on the change of multiphoton absorption mechanism induced by the transformation of defect species is proposed to interpret the experiments. Modeling results are in good agreement with the experiment data. | Xiaocong Peng Yuanan Zhao Yueliang Wang Zhen Cao Guohang Hu Jianda Shao | 2018 | High Power Laser Science and Engineering2018，6，3： | 2 |
| 17 | Label-free and real-time detection of specific binding of IgG proteins by oblique-incidence reflectivity difference method显示文摘The entire interaction process between anti-mouse immunoglobulin-G (IgG) and mouse IgG with a concentration range from 1 to 0.25 mg/mL has been label-free detected by the oblique incidence reflectivity difference (OIRD) method.We achieved the two-dimensional scanning images of OIRD Re{△ p △s } intensities before and after interactions as well as the curves of reaction dynamic processes.The experimental results suggest that OIRD method not only can label-free distinguish the different concentrations of proteins and detect biological microarrays,but also can real-time monitor the kinetic processes of biomolecular interactions. | SUN Yue HE LiPing DAI Jun WANG JingYi LÜ HuiBin WANG ShuFang JIN KuiJuan ZHOU YueLiang YANG GuoZhen | 2012 | Chinese Science Bulletin2012，57，22： | 2 |
| 18 | Availability modelling for periodically inspected systems under mixed maintenance policies显示文摘The availability of a periodic inspection system under mixed maintenance policies is studied in this paper.To accommodate the characteristic of multiple failure modes for complex systems,the system failures can be divided into two failure modes:hard failure and soft failure.When hard failure occurs,the corresponding corrective maintenance will be performed,taking a random time under the perfect maintenance policy;in contrast,if the soft failure is found,the corresponding preventive maintenance will be performed,taking a random time under the imperfect maintenance policy.The dynamic age setback model is adopted for imperfect maintenance,which can accurately reflect the fault characteristics of the degraded system.Then an analytical model for system steady state availability and instantaneous availability are derived.Moreover,the optimal method to maximize the system steady-state availability through adjusting the inspection interval is researched.According to the above research,the optimization of system unit time cost,preventive maintenance intervals and availability is researched.Finally,the developed approach is demonstrated by a numerical example. | LI Junliang CHEN Yueliang ZHANG Yong ZHANG Zhuzhu FAN Weijie | 2021 | Journal of Systems Engineering and Electronics2021，32，3： | 2 |
