| 1 | Integrating a weighted-average method into the random walk framework to generate individual friend recommendations显示文摘Friend recommendation is a fundamental service in both social networks and practical applications,and is influenced by user behaviors such as interactions, interests, and activities. In this study, we first conduct in-depth investigations on factors that affect recommendation results. Next, we design Friend++, a hybrid multi-individual recommendation model that integrates a weighted average method(WAM) into the random walk(RW) framework by seamlessly employing social ties, behavior context, and personal information. In Friend++, the first plus signifies recommending a new friend through network features, while the second plus stands for using node features. To verify our method, we conduct experiments on three social datasets crawled from the Sina microblog system(Weibo). Experimental results show that the proposed method significantly outperforms six baseline methods in terms of recall, precision, F1-measure, and MAP. As a final step, we describe a case study that demonstrates the scalability and universality of our method. Through discussion, we reach a meaningful conclusion: although common interests are more important than user activities in making recommendations, user interactions may be the most important factor in finding the most appropriate potential friends. | Jibing GONG Xiaoxia GAO Hong CHENG Jihui LIU Yanqing SONG Mantang ZHANG Yi ZHAO | 2017 | Science China(Information Sciences)2017，60，11： | 7 |
| 2 | Structural and magnetic properties of Sm_2Fe_(17-x)Nb_x (x = 0-4) alloys prepared by HDDR processes and their nitrides显示文摘Sm2Fe17-xNbxNy (x = 0-4) powder was synthesized by HDDR treatment and nitrogenation. The effects of partial Nb substitution for Fe on the structural and magnetic properties of Sm2Fe17?xNbx alloys and their nitrides were investigated. It was seen that Sm2(Fe,Nb)17 phase exists in both annealed and HDDR-treated Sm2Fe17?xNbx alloys. However, its content is decreased with the increase in Nb substitution. In annealed alloys, Sm2(Fe,Nb)17 phase becomes unstable and will dissociate into SmFe2 and Fe-rich phases when x > 1.5. With HDDR-treatment, the Nb concentration in recombined Sm2(Fe,Nb)17 phase is decreased, and the content of Fe-rich phases is increased. Sm2Fe17?xNbx powder exhibits dendritic cracks and fine particles with a size of less than 300 nm. In nitrogenated alloys, N atoms mainly enter 2:17-type phase to form Sm2(Fe,Nb)17Ny. Partial Nb atoms in Sm2(Fe,Nb)17Ny phase will be released or excluded by nitrogen atoms. Fe-rich phases increase, and are followed by the amorphous Sm2(Fe,Nb)17Ny phase. Nb substitution for Fe with x = 0.5 and 1.0 in Sm2Fe17?xNbxNy powders increases the coercivity and remanence. But when x is greater than 2.0, Nb substitution will dete- riorate the magnetic properties. | SUN Jibing CUI Chunxiang ZHANG Ying LI lin GAO Jianxia LIU Yuling | 2006 | Rare Metals2006，25，2： | 4 |
| 3 | Optimization of High-Gravity Chelated Iron Process for Removing H_2S Based on Response Surface Methodology显示文摘By using a mixture of N2 and H2S as the simulated APG(associated petroleum gas), the desulfurization experiment was performed in a cross-flow rotating packed bed(RPB) based on the chelated iron oxidation-reduction method. In order to determine the operating conditions of the system, the effects of the concentration of Fe3+ ions(ranging from 0.1 to 0.2 mol/L), the liquid-gas volume ratio(ranging from 15 to 25 L/m3) and the high gravity factor(ranging from 36 to 126) on the removal of H2 S were studied by means of the Box-Behnken design(BBD) under response surface methodology(RSM). The overall results have demonstrated that the BBD with an experimental design can be used effectively in the optimization of the desulfurization process. The optimal conditions based on both individualized and combined responses(at a Fe3+ ion concentration of 0.16 mol/L, a liquid-gas volume ratio of 20.67 L/m3 and a high gravity factor of 87) were found. Under this optimum condition, the desulfurization efficiency could reach 98.81% when the H2 S concentration was 7 g/m3 in APG. In this work, the sulfur product was analyzed by X-ray diffraction(XRD), scanning electron microscopy(SEM) and the energy dispersive X-ray spectrometer(EDX). The results of analysis show that the sulfur is made of the high-purity orthorhombic crystals, which are advantageous to environmental conservation. | Luo Ying Zhang Zhongzhe Qi Jibing Li Gang Qi Guisheng Liu Youzhi | 2015 | China Petroleum Processing & Petrochemical Technology2015，17，3： | 3 |
| 4 | Effect of Apigenin on Gap Junctional Intercellular Communication in Human Tenon's Capsule Fibroblasts显示文摘Purpose:To investigate the effect of apigenin on gap junctional intercellular communication (GJIC) in human Tenon's capsule fibroblasts (HTFs) and its underlying mechanism. Methods:After a 48 h treatment of cultured HTFs with apigenin.(80 μmol/L),the GJIC was detected by a scrape-loading/dye transfer technique with Lucifer yellow dye and rhodamine (Rh) dextran. The coupling index represents a quantification of GJIC where a high coupling index is associated with a greater number of cells demonstrating cell-cell communication through gap junction channels.The changes in connexin 43 (Cx43) distribution and the expression of Cx43 at the protein and mRNA levels were statistically compared between the two groups by means of immunocytochemistry, western blotting,and real-time polymerase chain reaction (PCR). Results:The functioning of GJIC in the HTFs was significantly enhanced after 48 hours by apigenin treatment when compared with the control cells. In the apigenin group, the intercellular dye transfer grade was above 9, while this value was only grade 3-4 in the control group. The coupling index was significantly increased up to 9.205±0.3621 in the apigenin group,compared with 5.1775 ±0.3177 in the control group (F=279.581, P=0.000). The expression of Cx43 at the protein and mRNA levels was significantly up-regulated in the apigenin group compared with the control group. Conclusion:Apigenin can significantly enhance the function of GJIC in HTFs by up-regulating the expression of Cx43 at both the protein and mRNA levels,suggesting that the enhancement of GJIC in HTFs by apigenin probably acts as an important mechanism underlying the inhibitory effect of apigenin on HTF proliferation. | Shanshan Liu Jibing Wang Huihui Zou Xudong Huang | 2013 | Eye Science2013，28，2： | 2 |

| 6 | Irreversible electroporation plus allogenic Vγ9Vδ2 T cells enhances antitumor effect for locally advanced pancreatic cancer patients显示文摘Immunotherapy has limited efficacy against locally advanced pancreatic cancer(LAPC)due to the presence of an immunosuppressive microenvironment(ISM).Irreversible electroporation(IRE)can not only induce immunogenic cell death,but also alleviate immunosuppression.This study aimed to investigate the antitumor efficacy of IRE plus allogeneicγδT cells in LAPC patients.A total of 62 patients who met the eligibility criteria were enrolled in this trial,then randomized into two groups(A:n=30 and B:n=32).All patients received IRE therapy and after receiving IRE,the group A patients received at least two cycles ofγδT-cell infusion as one course continuously.Group A patients had better survival than group B patients(median OS:14.5 months vs.11 months;median PFS:11 months vs.8.5 months).Moreover,the group A patients treated with multiple courses ofγδT-cell infusion had longer OS(17 months)than those who received a single course(13.5 months).IRE combined with allogeneicγδT-cell infusion is a promising strategy to enhance the antitumor efficacy in LAPC patients,yielding extended survival benefits. | Mao Lin Xiaoyan Zhang Shuzhen Liang Haihua Luo Mohammed Alnaggar Aihua Liu Zhinan Yin Jibing Chen Lizhi Niu Yong Jiang | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 2 |
| 7 | Diffusion Characteristics and Removal of Cyclohexane in Polyolefin Elastomer Melt显示文摘The diffusion coefficient of volatiles in polymer solutions is a crucial parameter to describe the mass transfer efficiency and ability of volatiles.In this research,polyolefin elastomer(POE)was used as a polymer,and cyclohexane was used as a volatile.A gravimetric analysis was applied to measure the diffusion coefficient of cyclohexane in POE.The devolatilization rate of the POE-cyclohexane system under different conditions was measured.The effects of temperature,film sample thickness,and initial concentration of volatiles on the devolatilization rate were discussed.Based on the devolatilization rate data,the average diffusion coefficient of cyclohexane in POE was obtained by fitting with a mathematical model.The experimental results indicate that the devolatilization rate increased with increasing temperature and initial concentration of volatiles,but it decreased with increasing sample thickness.As the thickness increased,the overall diffusion resistance increased.As the temperature increased,the molecular movement increased,resulting in the increase of average diffusion coefficient.The relationship between the diffusion coefficient of the POE-cyclohexane system and temperature follows the Arrhenius law.The diffusion activation energy E=6201.73 J/mol,and the pre-exponential factor of the diffusion coefficient D0=2.64×10^(-10) m^(2)/s.This work can provide basic data for exploring the devolatilization of POE polymers and serves as a useful reference for enhancing the effect of devolatilization. | Qi Jibing Yang Tong Liu Yandong Yuan Zhiguo Zhang Qiaoling Liu Youzhi Yi Jianjun | 2022 | China Petroleum Processing & Petrochemical Technology2022，24，4： | 1 |

| 9 | New Metabolic Alterations and A Predictive Marker Pipecolic Acid in Sera for Esophageal Squamous Cell Carcinoma显示文摘Esophageal squamous cell carcinoma(ESCC)is a major histological subtype of esophageal cancer with a poor prognosis.Although several serum metabolomic investigations have been reported,ESCC tumor-associated metabolic alterations and predictive biomarkers in sera have not been defined.Here,we enrolled 34 treatment-naive patients with ESCC and collected their pre-and post-esophagectomy sera together with the sera from 34 healthy volunteers for a metabolomic survey.Our comprehensive analysis identified ESCC tumor-associated metabolic alterations as represented by a panel of 12 serum metabolites.Notably,postoperative abrosia and parenteral nutrition substantially perturbed the serum metabolome.Furthermore,we performed an examination using sera from carcinogen-induced mice at the dysplasia and ESCC stages and identified three ESCC tumor-associated metabolites conserved between mice and humans.Notably,among these metabolites,the level of pipecolic acid was observed to be progressively increased in mouse sera from dysplasia to cancerization,and it could be used to accurately discriminate between mice at the dysplasia stage and healthy control mice.Furthermore,this metabolite is essential for ESCC cells to restrain oxidative stress-induced DNA damage and cell proliferation arrest.Together,this study revealed a panel of 12 ESCC tumor-associated serum metabolites with potential for monitoring therapeutic efficacy and disease relapse,presented evidence for refining parenteral nutrition composition,and highlighted serum pipecolic acid as an attractive biomarker for predicting ESCC tumorigenesis. | Lei Liu Jia Wu Minxin Shi Fengying Wang Haimin Lu Jibing Liu Weiqin Chen Guanzhen Yu Dan Liu Jing Yang Qin Luo Yan Ni Xing Jin Xiaoxia Jin Wen-Lian Chen | 2022 | Genomics, Proteomics & Bioinformatics2022，20，4： | 0 |
| 10 | Determination of the Henry’s Law Constant of Hexane in High-Viscosity Polymer Systems显示文摘The Henry’s law constant of volatiles in polymer systems is a crucial parameter reflecting the gas-liquid equilibrium,which is very important for devolatilization.In this research,polyolefin elastomer(POE)-cyclohexane and polydimethylsiloxane(PDMS)-hexane systems were studied,and the Henry’s law constant was obtained by measuring the gas phase equilibrium partial pressure when polymer solutions containing different mass fractions of volatiles reached a saturated state.The effects of temperature,type of volatiles,and polymer viscosity on the gas phase equilibrium partial pressure and Henry’s law constant of the volatiles were investigated.The results indicate that,with the increase of temperature and polymer viscosity,the gas phase equilibrium partial pressure and Henry’s law constant of volatiles increase.As temperature increases,the solubility of gas in liquid decreases.The relationship between the Henry’s law constant and temperature is consistent with the Arrhenius law.In the PDMS-hexane system,the gas phase equilibrium partial pressure and Henry’s law constant of n-hexane are higher than those of cyclohexane.The obtained Henry’s law constants can be used as a reference for perfecting the devolatilization process and improving the devolatilization effect. | Qi Jibing Li Yuliang Liu Youzhi Yang Tong Liu Yandong Yuan Zhiguo Yi Jianjun | 2023 | China Petroleum Processing & Petrochemical Technology2023，25，1： | 0 |
| 11 | Nonreciprocal microwave transmission under the joint mechanism of phase modulation and magnon Kerr nonlinearity effect显示文摘Nonreciprocal microwave devices,in which the transmission of waves is non-symmetric between two ports,are indispensable for the manipulation of information processing and communication.In this work,we show the nonreciprocal microwave transmission in a cavity magnonic system under the joint mechanism of phase modulation and magnon Kerr nonlinearity effect.In contrast to the schemes based on the standard phase modulation or magnon Kerr nonlinearity,we find that the joint mechanism enables the nonreciprocal transmission even at low power and makes us obtain a high nonreciprocal isolation ratio.Moreover,when two microwave modes are coupled to the magnon mode via a different coupling strength,the presented strong nonreciprocal response occurs,and it makes the nonreciprocal transmission manipulating by the magnetic field within a large adjustable range possible,which overcomes narrow operating bandwidths.This study may provide promising opportunities to realize nonreciprocal structures for wave transmission. | Cui Kong Jibing Liu Hao Xiong | 2023 | Frontiers of physics2023，18，1： | 0 |
