| 1 | Cementation of sand grains based on carbonate precipitation induced by microorganism显示文摘Microbes can produce 2 3 CO_3^(2-)in an environment conductive to precipitation,so the incompact sands will be consolidated.This technology is environmentally friendly not only because it gives strength to the sand body,but also it allows water to penetrate into the sand body,which is unlike silicate cement that will destroy the ecosystem of the earth.After comparing the activity of three kinds of bacteria,the most suitable one was chosen for the study.However,the activity of this bacterium was still not high enough for the purpose,so it was purified.A suitable program for the consolidation and cementation of sands was also found in the experiment.The compressive strength and the porosity of the cemented sand body were tested to characterize the cementation effectiveness.XRD analysis showed that a new phase of calcite was produced between sand grains.The content of calcite was detected by TG.The study showed that the precipitation program was quite important to obtain a sound cemented sand body in addition to the activity of the bacteria. | QIAN ChunXiang,PAN QingFeng &WANG RuiXing Jiangsu Key Laboratory of Construction Materials,School of Materials Science&Engineering,Southeast University,Nanjing 211189,China | 2010 | Science China(Technological Sciences)2010，53，8： | 34 |
| 2 | Dynamic Topology Multi Force Particle Swarm Optimization Algorithm and Its Application显示文摘Particle swarm optimization(PSO) algorithm is an effective bio-inspired algorithm but it has shortage of premature convergence. Researchers have made some improvements especially in force rules and population topologies. However, the current algorithms only consider a single kind of force rules and lack consideration of comprehensive improvement in both multi force rules and population topologies. In this paper, a dynamic topology multi force particle swarm optimization(DTMFPSO) algorithm is proposed in order to get better search performance. First of all, the principle of the presented multi force particle swarm optimization(MFPSO) algorithm is that different force rules are used in different search stages, which can balance the ability of global and local search. Secondly, a fitness-driven edge-changing(FE) topology based on the probability selection mechanism of roulette method is designed to cut and add edges between the particles, and the DTMFPSO algorithm is proposed by combining the FE topology with the MFPSO algorithm through concurrent evolution of both algorithm and structure in order to further improve the search accuracy. Thirdly, Benchmark functions are employed to evaluate the performance of the DTMFPSO algorithm, and test results show that the proposed algorithm is better than the well-known PSO algorithms, such as μPSO, MPSO, and EPSO algorithms. Finally, the proposed algorithm is applied to optimize the process parameters for ultrasonic vibration cutting on Si C wafer, and the surface quality of the Si C wafer is improved by 12.8% compared with the PSO algorithm in Ref. [25]. This research proposes a DTMFPSO algorithm with multi force rules and dynamic population topologies evolved simultaneously, and it has better search performance. | CHEN Dongning ZHANG Ruixing YAO Chengyu ZHAO Zheyu | 2016 | Chinese Journal of Mechanical Engineering2016，29，1： | 13 |
| 3 | A cementation method of loose particles based on microbe-based cement显示文摘Microbe-based cement has been widely reported in recent literatures. It is a new method of consolidating loose fine particles, which relies on the bacterially induced formation of a compatible carbonate precipitation around individual particles and at particle-particle contacts. Materials and cementation procedure are two major factors that influence the cementation performance of microbe-based cement. Besides, there are some other factors related to the performance, such as pH, temperature, metabolism activity, the flushed times of bacterial solution, concentration of substrate and calcium ion, etc., which affect consolidation function. The assessment methods for cementation process are carried out by various techniques. The performance of consolidation loose grains based on microbe-based cement is tested with the help of experiment. In this paper a review is presented on the cementation mechanism of microbe-based cement, techniques utilized to monitor cementation process, the consolidated performance by microbe-based cement and bond factors. | RONG Hui QIAN ChunXiang WANG RuiXing | 2011 | Science China(Technological Sciences)2011，54，7： | 8 |
| 4 | Study on soil solidification based on microbiological precipitation of CaCO_3显示文摘The soil solidifying technology started booming from the 1940s and formed an integrated cross-discipline.This paper aimed to study the effect and mechanism of soil solidification by microorganisms.Soil specimens treated by different methods were designed.Then the compressive strengths of these specimens on day 7 were tested and the situ bacteria culturing technique in soil was investigated.Finally the mechanism of soil solidification by microorganisms was explored according to the decomposition rate of substrate,pH value and the SEM and XRD analysis.Experimental results showed that the soil could be solidified by filling enhancement and precipitation of microorganisms.The compressive strength increased with bacteria A but decreased with substrate B,and soil specimen got a higher strength with bacteria situ cultured.The suitable pH value for bacteria A was 8–9,and the delay of lime addition could make substrate decomposition more completely,lower the influence by the existence of substrate,and improve the strength.In XRD and SEM images,precipitation of CaCO3 could be speculated. | LU WangJie,QIAN ChunXiang & WANG RuiXing School of Materials Science & Engineering,Jiangsu Key Laboratory for Construction Materials,Southeast University,Nanjing 210089,China | 2010 | Science China(Technological Sciences)2010，53，9： | 6 |
| 5 | Efficient Computational Method for the Non-Probabilistic Reliability of Linear Structural Systems显示文摘The non-probabilistic reliability in higher dimensional situations cannot be calculated efficiently using traditional methods, which either require a large amount of calculation or cause significant error. In this study, an efficient computational method is proposed for the calculation of non-probabilistic reliability based on the volume ratio theory, specifically for linear structural systems. The common expression for non-probabilistic reliability is obtained through formula derivation with the amount of computation considerably reduced. The compatibility between non-probabilistic and probabilistic safety measures is demonstrated through the Monte Carlo simulation. The high efficiency of the presented method is verified by several numerical examples. | Ruixing Wang Xiao jun Wang Lei Wang Xianjia Chen | 2016 | Acta Mechanica Solida Sinica2016，29，3： | 5 |
| 6 | Ca^(2+)-supplying black phosphorus-based scaffolds fabricated with microfluidic technology for osteogenesis显示文摘Effective osteogenesis remains a challenge in the treatment of bone defects.The emergence of artificial bone scaffolds provides an attractive solution.In this work,a new biomineralization strategy is proposed to facilitate osteogenesis through sustaining supply of nutrients including phosphorus(P),calcium(Ca),and silicon(Si).We developed black phosphorus(BP)-based,three-dimensional nanocomposite fibrous scaffolds via microfluidic technology to provide a wealth of essential ions for bone defect treatment.The fibrous scaffolds were fabricated from 3D poly(L-lactic acid)(PLLA)nanofibers(3D NFs),BP nanosheets,and hydroxyapatite(HA)-porous SiO2 nanoparticles.The 3D BP@HA NFs possess three advantages:i)stably connected pores allow the easy entrance of bone marrow-derived mesenchymal stem cells(BMSCs)into the interior of the 3D fibrous scaffolds for bone repair and osteogenesis;ii)plentiful nutrients in the NFs strongly improve osteogenic differentiation in the bone repair area;iii)the photothermal effect of fibrous scaffolds promotes the release of elements necessary for bone formation,thus achieving accelerated osteogenesis.Both in vitro and in vivo results demonstrated that the 3D BP@HA NFs,with the assistance of NIR laser,exhibited good performance in promoting bone regeneration.Furthermore,microfluidic technology makes it possible to obtain high-quality 3D BP@HA NFs with low costs,rapid processing,high throughput and mass production,greatly improving the prospects for clinical application.This is also the first BP-based bone scaffold platform that can self-supply Ca^(2+),which may be the blessedness for older patients with bone defects or patients with damaged bones as a result of calcium loss. | Zhanrong Li Xingcai Zhang Jiang Ouyang Dandan Chu Fengqi Han Liuqi Shi Ruixing Liu Zhihua Guo Grace X.Gu Wei Tao Lin Jin Jingguo Li | 2021 | Bioactive Materials2021，6，11： | 4 |
| 7 | Six sigma robust design optimization for thermal protection system of hypersonic vehicles based on successive response surface method显示文摘Lightweight design is important for the Thermal Protection System(TPS) of hypersonic vehicles in that it protects the inner structure from severe heating environment. However, due to the existence of uncertainties in material properties and geometry, it is imperative to incorporate uncertainty analysis into the design optimization to obtain reliable results. In this paper, a six sigma robust design optimization based on Successive Response Surface Method(SRSM) is established for the TPS to improve the reliability and robustness with considering the uncertainties. The uncertain parameters related to material properties and thicknesses of insulation layers are considered and characterized by random variables following normal distributions. By employing SRSM, the values of objective function and constraints are approximated by the response surfaces to reduce computational cost. The optimization is an iterative process with response surfaces updating to find the true optimal solution. The optimization of the nose cone of hypersonic vehicle cabin is provided as an example to illustrate the feasibility and effectiveness of the proposed method. | Jingjing ZHU Xiaojun WANG Haiguo ZHANG Yuwen LI Ruixing WANG Zhiping QIU | 2019 | Chinese Journal of Aeronautics2019，32，9： | 4 |
| 8 | Quercetin promotes human epidermal stem cell proliferation through the estrogen receptor/β-catenin/c-Myc/cyclin A2 signaling pathway显示文摘Skin epidermal stem cells(EpSCs)play an important role in wound healing.Quercetin is a phytoestrogen reported to accelerate skin wound healing,but its effect on EpSCs is unknown.In this study,we investigated the effect of quercetin on human EpSC proliferation and explored the underlying mechanisms.We found that quercetin at 0.1~1μM significantly promoted EpSC proliferation and increased the number of cells in S phase.The pro-proliferative effect of quercetin on EpSCs was confirmed in cultured human skin tissue.Mechanistic studies showed that quercetin significantly upregulated the expressions ofβ-catenin,c-Myc,and cyclins A2 and E1.Inhibitor forβ-catenin or c-Myc significantly inhibited quercetin-induced EpSC proliferation.Theβ-catenin inhibitor XAV-939 suppressed quercetin-induced expressions ofβ-catenin,c-Myc,and cyclins A2 and E1.The c-Myc inhibitor 10058-F4 inhibited the upregulation of c-Myc and cyclin A2 by quercetin.Pretreatment of EpSCs with estrogen receptor(ER)antagonist ICI182780,but not the G protein-coupled ER1 antagonist G15,reversed quercetin-induced cell proliferation and upregulation ofβ-catenin,c-Myc,and cyclin A2.Collectively,these results indicate that quercetin promotes EpSC proliferation through ER-mediated activation ofβ-catenin/c-Myc/cyclinA2 signaling pathway and ER-independent upregulation of cyclin E1 and that quercetin may accelerate skin wound healing through promoting EpSC proliferation.As EpSCs are used not only in clinic to treat skin wounds but also as seed cells in skin tissue engineering,quercetin is a useful reagent to expand EpSCs for basic research,skin wound treatment,and skin tissue engineering. | Zhaodong Wang Guangliang Zhang Yingying Le Jihui Ju Ping Zhang Dapeng Wan Qiang Zhao Guangzhe Jin Hao Su Jinwei Liu Jiaxuan Feng Yi Fu Ruixing Hou | 2020 | Acta Biochimica et Biophysica Sinica2020，52，10： | 3 |
| 9 | Deficiency of two-pore segment channel 2 contributes to systemic lupus erythematosus via regulation of apoptosis and cell cycle显示文摘Background:Systemic lupus erythematosus(SLE)is a complex autoimmune disease,and the mechanism of SLE is yet to be fully elucidated.The aim of this study was to explore the role of two-pore segment channel 2(TPCN2)in SLE pathogenesis.Methods:Quantitative reverse transcription polymerase chain reaction(qRT-PCR)was used to detect the expression ofTPCN2 in SLE.We performed a loss-of-function assay by lentiviral construct in Jurkat and THP-1 cell.Knockdown ofTPCN2 were confirmed at the RNA level by qRT-PCR and protein level by Western blotting.Cell Count Kit-8 and flow cytometry were used to analyze the cell proliferation,apoptosis,and cell cycle ofTPCN2-deficient cells.In addition,gene expression profile ofTPCN2-deficient cells was analyzed by RNA sequencing(RNA-seq).Results:TPCN2 knockdown with short hairpin RNA(shRNA)-mediated lentiviruses inhibited cell proliferation,and induced apoptosis and cell-cycle arrest of G2/M phase in both Jurkat and THP-1 cells.We analyzed the transcriptome of knockdown-TPCN2-Jurkat cells,and screened the differential genes,which were enriched for the G2/M checkpoint,complement,and interleukin-6-Janus kinase-signal transducer and activator of transcription pathways,as well as changes in levels of forkhead box O,phosphatidylinositol 3-kinase/protein kinase B/mechanistic target of rapamycin,and T cell receptor pathways;moreover,TPCN2 significantly influenced cellular processes and biological regulation.Conclusion:TPCN2 might be a potential protective factor against SLE. | Keke Li Jingkai Xu Ke Xue Ruixing Yu Chengxu Li Wenmin Fei Xiaoli Ning Yang Han Ziyi Wang Jun Shu Yong Cui | 2022 | Chinese Medical Journal2022，，4： | 2 |

| 11 | Dynamic rupture of metal sheet subjected to laser irradiation and tangential subsonic airflow显示文摘To reproduce the premature rupture process of metal sheet subjected to laser irradiation with subsonic airflow,which is an interesting phenomenon observed in the experiments given by Lawrence Livermore National Laboratory,a coupled numerical model considering the interaction and evolution of metal elastoplastic deformation and aerodynamic pressure profile is presented.With the thermal elastoplastic constitutive relationship and failure criterion,the simulated failure modes and dynamic rupture process are basically consistent with the experimental results,indicating plastic flow and multiple fracturing is the main failure mechanism.Compared with the case of non-airflow,subsonic airflow not only accelerates deformation,but also turns the bugle deformation,plastic strain and rupture mode into asymmetric. | Xiaodong Xing Te Ma Ruixing Wang Chenyu Cao Hongwei Song Chenguang Huang | 2018 | Theoretical & Applied Mechanics Letters2018，8，4： | 2 |
