1Microstructure and mechanical properties of hypereutectic Al-Si alloy modified with Cu-P显示文摘The microstructure and mechanical properties of Al-14.6Si castings modified by Cu-P master alloy under different conditions were studied with optical microscope(OM) and mechanical testing and simulation(MTS).The results indicate that the Cu-P master alloy possesses not only obvious modification effect,but also longevity effect with more than 8 h on the hypereutectic Al-Si alloy.It is shown from thermal calculation,scanning electron microscope(SEM),and energy dispersive analysis of X-rays(EDAX) that the modification mechanism of Cu-P on primary silicon in the castings is heterogeneous nucleation around AlP particles.The Cu-P master alloy has no or little modifying effect on eutectic silicon,even though it has obvious modification on primary silicon in the castings.This may be because of the fast transformation of eutectic silicon at a very narrow temperature,which will notably weaken the role of AlP particles as heterogeneous nuclei for eutectic silicon.ZHANG Henghua DUAN Haili SHAO Guangjie XU Luoping 2008Rare Metals2008,27,1:35

4Preparation and Characterization of Three Monoclonal Antibodies against HIV-1 p24 Capsid Protein显示文摘HIV-1 p24 detection provides a means to aid the early diagnosis of HIV-1 infection, track the progression of disease and assess the efficacy of antiretroviral therapy. In the present study, three monoclonal antibodies (mAbs) p3JB9, p5F1 and p6F4 against HIV-1 p24 were generated. All mAbs could detect p24 of HIV-1IIIB, HIV-1Ada-M, HIV-174V mAbs p5F1 and p6F4 could detect HIV-1KM018, while p3JB9 could not. Three mAbs did not react with HIV-2ROD, HIV-2CBL-20 and SIVagmTYO-1. The recognized epitope of p5F1 was located on the Gag amino acid region DCKTILKALGPAATLEEMMTAC. The p5F1 was used to establish a modified sandwich ELISA with rabbit anti-p24 serum and showed good specificity and high sensitivity, which has been used to measure HIV-1 p24 antigen levels in research.Guangjie Liu Jianping Wang Jianchun Xiao Zhiwei Zhao Yongtang Zheng 2007Cellular & Molecular Immunology2007,4,3:14
5Combined obeticholic acid and apoptosis inhibitor treatment alleviates liver fibrosis显示文摘Obeticholic acid(OCA), the first FXR-targeting drug, has been claimed effective in the therapy of liver fibrosis. However, recent clinical trials indicated that OCA might not be effective against liver fibrosis, possibly due to the lower dosage to reduce the incidence of the side-effect of pruritus. Here we propose a combinatory therapeutic strategy of OCA and apoptosis inhibitor for combating against liver fibrosis. CCl4-injured mice, D-galactosamine/LPS(GalN/LPS)-treated mice and cycloheximide/TNFα(CHX/TNFα)-treated HepG2 cells were employed to assess the effects of OCA, or together with IDN-6556, an apoptosis inhibitor. OCA treatment significantly inhibited hepatic stellate cell(HSC)activation/proliferation and prevented fibrosis. Elevated bile acid(BA) levels and hepatocyte apoptosis triggered the activation and proliferation of HSCs. OCA treatment reduced BA levels but could not inhibit hepatocellular apoptosis. An enhanced anti-fibrotic effect was observed when OCA was co-administrated with IDN-6556. Our study demonstrated that OCA inhibits HSCs activation/proliferation partially by regulating BA homeostasis and thereby inhibiting activation of HSCs. The findings in this study suggest that combined use of apoptosis inhibitor and OCA at lower dosage represents a novel therapeutic strategy for liver fibrosis.Jiyu Zhou Ningning Huang Yitong Guo Shuang Cui Chaoliang Ge Qingxian He Xiaojie Pan Guangji Wang Hong Wang Haiping Hao 2019Acta Pharmaceutica Sinica B2019,9,3:13
6NEW NONSTANDARD JOB SHOP SCHEDULING ALGORITHM显示文摘Considering the complex constraint between operations in nonstandard job shop scheduling problem (NJSSP), critical path of job manufacturing tree is determined according to priority scheduling function constructed. Operations are divided into dependent operations and independent operations with the idea of subsection, and corresponding scheduling strategy is put forward according to operation characteristic in the segment and the complementarities of identical function machines. Forward greedy rule is adopted mainly for dependent operations to make operations arranged in the right position of machine selected, then each operation can be processed as early as possible, and the total processing time of job can be shortened as much as possible. For independent operations optimum scheduling rule is adopted mainly, the inserting position of operations will be determined according to the gap that the processing time of operations is subtracted from idle time of machine, and the operation will be inserted in the position with minimal gap. Experiments show, under the same conditions, the result that operations are scheduled according to the object function constructed, and the scheduling strategy adopted is better than the result that operations are scheduled according to efficiency scheduling algorithm.XIE Zhiqiang YE Guangjie ZHANG Dali TAN Guangyu 2008Chinese Journal of Mechanical Engineering2008,21,4:10
7Textural Evolution of AZ31B Magnesium Alloy Sheets Undergoing Repeated Unidirectional Bending at Room Temperature显示文摘In this paper, repeated unidirectional bending (RUB), was applied to improve the texture of AZ31B magnesium alloy sheets so as to enhance their stamping properties. The samples undergoing RUB were annealed at different temperatures. The mechanical properties, formability, textural components and microstructure of the samples before and after RUB were characterized and compared. It was found that the basal textural component was reduced dramatically by RUB, and that (12ˉ12) and (12ˉ11) textural components appeared. Annealing has a great effect on the mechanical properties of samples undergoing RUB. The plasticity and stamping formability of samples were greatly improved by RUB and annealing at 260?C for 1 h, and elongation to fracture and Erichsen value were increased to 38% and 67%, respectively.Guangsheng Huang Wei Xu Guangjie Huang Hongcheng Li Bo Song 2009Journal of Materials Science & Technology2009,25,3:9

13Mechanisms and field test of solution mining by self-resonating cavitating water jets显示文摘Rapid solution mining is the key to cavern construction in salt formations. Rapid solution mining technology with self-resonating cavitating water jets is described in this paper. It can generate three main physical effects: helical flow dissolution, self-resonating cavitating jet erosion, and ultrasonic waves. A self-resonating cavitating nozzle was also designed with the principles based on theory of fluid transients and hydro-acoustics. Under ambient pressure, the experimental results show that the impulse amplitude of pressure reaches a peak at a standoff distance of 5-13 times the nozzle outlet diameter and the cutting ability of self-resonating cavitating jets is twice that of conventional jets under the same conditions. Compared with the conventional mining method, the field test indicates that rapid solution mining technology with self-resonating cavitating jets can speed the construction by more than 2 times at the pocket stage of cavern development.Song Xianzhi Li Gensheng Yuan Jinping Tian Zhonglan Shen Ruichen Yuan Guangjie Huang Zhongwei 2010Petroleum Science2010,7,3:5
14LSTM-based argument recommendation for non-API methods显示文摘Automatic code completion is one of the most useful features provided by advanced IDEs.Argument recommendation,as a special kind of code completion,is widely used as well.While existing approaches focus on argument recommendation for popular APIs,a large number of non-API invocations are requesting for accurate argument recommendation as well.To this end,we propose an LSTM-based approach to recommending non-API arguments instantly when method calls are typed in.With data collected from a large corpus of open-source applications,we train an LSTM neural network to recommend actual arguments based on identifiers of the invoked method,the corresponding formal parameter,and a list of syntactically correct candidate arguments.To feed these identifiers into the LSTM neural network,we convert them into fixed-length vectors by Paragraph Vector,an unsupervised neural network based learning algorithm.With the resulting LSTM neural network trained on sample applications,for a given call site we can predict which of the candidate arguments is more likely to be the correct one.We evaluate the proposed approach with tenfold validation on 85 open-source C applications.Results suggest that the proposed approach outperforms the state-of-the-art approaches in recommending non-API arguments.It improves the precision significantly from 71.46%to 83.37%.Guangjie LI Hui LIU Ge LI Sijie SHEN Hanlin TANG 2020Science China(Information Sciences)2020,63,9:5
