2Integrating 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 2017Science China(Information Sciences)2017,60,11:7

4Structural 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 2006Rare Metals2006,25,2:4
5Optimization 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 2015China Petroleum Processing & Petrochemical Technology2015,17,3:3
6Irreversible 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 2020Signal Transduction and Targeted Therapy2020,5,1:2
7Fabrication and magnetic properties of Sm_3(Fe,Ti)_(29)N_x/α-Fe dual-phase nanocomposite permanent magnetic material显示文摘Sm3(Fe,Ti)29Nx/α-Fe dual-phase nanometer magnetic material was fabricated through rapid solidification, crystallization and nitridation of Sm-Fe (Ti) alloy. The effect of combination of rapid solidification and Ti alloy addition on the phase for- mation and microstructure of the Sm-Fe alloy is investigated in this paper. The mi- crostructure of amorphous phase and dual-phase nano-grain crystals before and after crystallization annealing were observed using a high-resolution transmission electron microscope (HREM). The dual-phase nano-grains after annealing were compacted together with a clear interface with the direct exchange-coupling mechanism. Different annealing processes were used to examine the melt-spun alloy. Comparison of the images of SEM showed that annealing at 750 ℃ for 10 min was most suitable to get homogeneous and nano-grains. No obvious kink was de- tected in the second quadrant of the hysteresis loop like a single hard magnet, and strong exchange coupling was found between hard magnets and soft magnets.CUI ChunXiang, ZHANG Ying, SUN JiBing & WANG Ru School of Materials Science and Engineering, Hebei University of Technology, Tianjin 300130, China 2007Science China(Technological Sciences)2007,50,2:1

9Diffusion 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 2022China Petroleum Processing & Petrochemical Technology2022,24,4:1

12Recent advances in hybrid water electrolysis for energy-saving hydrogen production显示文摘Electricity-driven water splitting to convert water into hydrogen(H_(2)has been widely regarded as an efficient approach for H_(2)production.Nevertheless,the energy conversion efficiency of it is greatly limited due to the disadvantage of the sluggish kinetic of oxidation evolution reaction(OER).To effectively address the issue,a novel concept of hybrid water electrolysis has been developed for energy–saving H_(2)production.This strategy aims to replace the sluggish kinetics of OER by utilizing thermodynamically favorable organics oxidation reaction to replace OER.Herein,recent advances in such water splitting system for boosting H_(2)evolution under low cell voltage are systematically summarized.Some notable progress of different organics oxidation reactions coupled with hydrogen evolution reaction(HER)are discussed in detail.To facilitate the development of hybrid water electrolysis,the major challenges and perspectives are also proposed.Di Li Jibing Tu Yingying Lu Bing Zhang 2023Green Chemical Engineering2023,4,1:1
13Study of thermoelectric enhanced SERS and photocatalysis with ZnO-metal nanorod arrays显示文摘Herein,a thermoelectric induced surface-enhanced Raman scattering(SERS)substrate consisting of ZnO nanorod arrays and metal nanoparticles is proposed.The intensities of SERS signals are further enhanced by an order of magnitude and the limit of detection(LOD)for the molecules is reduced by at least one order of magnitude after the application of a thermoelectric potential.The enhancement mechanism is analyzed carefully and thoroughly based on the experimental and theoretical results,thus proving that the thermoelectric-induced enhancement of the SERS signals should be classified as a chemical contribution.Furthermore,it is proved that the electric regulation mechanism is universally applicable,and the fabricated substrate realizes enormous enhancements for various types of molecules,such as rhodamine 6G,methyl orange,crystal violet,amaranth,and biological molecules.Additionally,the proposed electric-induced SERS(E-SERS)substrate is also realized to monitor and manipulate the plasmon-activated redox reactions.We believe that this study can promote the course of the research on ESERS and plasmon-enhanced photocatalysts.Baoqiang Du Jibing Tan Chang Ji Mingrui Shao Xiaofei Zhao Jing Yu Chao Zhang Chuansong Chen Hui Pan Baoyuan Man Zhen Li 2023Nano Research2023,16,4:0
14Ferroelectrically modulate the Fermi level of graphene oxide to enhance SERS response显示文摘Surface-enhanced Raman scattering(SERS)substrates based on chemical mechanism(CM)have received widespread attentions for the stable and repeatable signal output due to their excellent chemical stability,uniform molecular adsorption and controllable molecular orientation.However,it remains huge challenges to achieve the optimal SERS signal for diverse molecules with different band structures on the same substrate.Herein,we demonstrate a graphene oxide(GO)energy band regulation strategy through ferroelectric polarization to facilitate the charge transfer process for improving SERS activity.The Fermi level(Ef)of GO can be flexibly manipulated by adjusting the ferroelectric polarization direction or the temperature of the ferroelectric substrate.Experimentally,kelvin probe force microscopy(KPFM)is employed to quantitatively analyze the Ef of GO.Theoretically,the density functional theory calculations are also performed to verify the proposed modulation mechanism.Consequently,the SERS response of probe molecules with different band structures(R6G,CV,MB,PNTP)can be improved through polarization direction or temperature changes without the necessity to redesign the SERS substrate.This work provides a novel insight into the SERS substrate design based on CM and is expected to be applied to other two-dimensional materials.Mingrui Shao Chang Ji Jibing Tan Baoqiang Du Xiaofei Zhao Jing Yu Baoyuan Man Kaichen Xu Chao Zhang Zhen Li 2023Opto-Electronic Advances2023,6,11:0
