| 2 | Critical role of SDF-1/CXCR4 signaling pathway in stem cell homing in the deafened rat cochlea after acoustic trauma显示文摘Previous animal studies have shown that stromal cell-derived factor-1(SDF-1)/CXC chemokine receptor-4(CXCR4) signaling pathway plays an important role in the targeted migration of bone marrow-derived mesenchymal stem cells(BMSCs) to the injured area. In the present study, we aimed to investigate the potential role of chemotactic SDF-1/CXCR4 signaling pathway in the homing of transplanted BMSCs to the injured cochlea after noise-induced hearing loss(NIHL) in a rat model. White noise exposure(110 d B) paradigm was used for hearing loss induction in male rats for 6 hours in 5 days. Distortion-product otoacoustic emission(DPOAE) responses were recorded before the experiment and post noise exposure. Hoechst 33342-labeled BMSCs and CXCR4 antagonist(AMD3100)-treated BMSCs were injected into the rat cochlea through the round window. SDF-1 protein expression in the cochlear tissue was assayed using western blot assay. The number of labeled BMSCs reaching the endolymph was determined after 24 hours. SDF-1 was significantly increased in the cochlear tissue of rats in the noise exposure group than in the control group. The number of Hoechst 33342-labeled BMSCs reaching the endolymph of the cochlea was significantly smaller in the AMD3100-treated BMSCs group than in the normal BMSCs group. Our present findings suggest that the SDF-1/CXCR4 signaling pathway has a critical role in BMSCs migration to the injured cochlea in a rat model of noise-induced hearing loss. | Ali Asghar Peyvandi Navid Ahmady Roozbahany Hassan Peyvandi Hojjat-Allah Abbaszadeh Niloofar Majdinasab Mohammad Faridan Somayeh Niknazar | 2018 | Neural Regeneration Research2018，13，1： | 11 |
| 3 | Improved prediction of slope stability using a hybrid stacking ensemble method based on finite element analysis and field data显示文摘Slope failures lead to catastrophic consequences in numerous countries and thus the stability assessment for slopes is of high interest in geotechnical and geological engineering researches.A hybrid stacking ensemble approach is proposed in this study for enhancing the prediction of slope stability.In the hybrid stacking ensemble approach,we used an artificial bee colony(ABC)algorithm to find out the best combination of base classifiers(level 0)and determined a suitable meta-classifier(level 1)from a pool of 11 individual optimized machine learning(OML)algorithms.Finite element analysis(FEA)was conducted in order to form the synthetic database for the training stage(150 cases)of the proposed model while 107 real field slope cases were used for the testing stage.The results by the hybrid stacking ensemble approach were then compared with that obtained by the 11 individual OML methods using confusion matrix,F1-score,and area under the curve,i.e.AUC-score.The comparisons showed that a significant improvement in the prediction ability of slope stability has been achieved by the hybrid stacking ensemble(AUC?90.4%),which is 7%higher than the best of the 11 individual OML methods(AUC?82.9%).Then,a further comparison was undertaken between the hybrid stacking ensemble method and basic ensemble classifier on slope stability prediction.The results showed a prominent performance of the hybrid stacking ensemble method over the basic ensemble method.Finally,the importance of the variables for slope stability was studied using linear vector quantization(LVQ)method. | Navid Kardani Annan Zhou Majidreza Nazem Shui-Long Shen | 2021 | Journal of Rock Mechanics and Geotechnical Engineering2021，13，1： | 10 |
| 4 | Explicit reinforcement models for fully-grouted rebar rock bolts显示文摘This paper investigates the explicit use of rock reinforcement in a discontinuous stress analysis model.A series of numerical experiments was undertaken to evaluate the performance of local and global reinforcement models implemented in universal distinct element code(UDEC).This was made possible by calibrating the reinforcement models to the laboratory behavior of a fully-grouted rebar bolt tested under pure pull and pure shear loading conditions.The model calibration focuses on matching different loading stages of the force-displacement curve including the initial elastic response,the hardening behavior and the bolt rupture.The paper concludes with a discussion on the suitability of the different reinforcement models in UDEC including their advantages and limitations.Finally,it addresses the choice of input parameters required for a realistic simulation of fully-grouted rebar bolts. | Navid Bahrani John Hadjigeorgiou | 2017 | Journal of Rock Mechanics and Geotechnical Engineering2017，9，2： | 10 |

| 6 | NUMERICAL SIMULATION OF FLOW OVER TWO SIDE-BY-SIDE CIRCULAR CYLINDERS显示文摘In the present paper, the unsteady, viscous, incompressible and 2-D flow around two side-by-side circular cylinders was simulated using a Cartesian-staggered grid finite volume based method. A great-source term technique was employed to identify the solid bodies (cylinders) located in the flow field and boundary conditions were enforced by applying the ghost-cell technique. Finally, the characteristics of the flow around two side-by-side cylinders were comprehensively obtained through several computational simulations. The computational simulations were performed for different transverse gap ratios (1.5≤T/D≤4) in laminar (Re=100,200) and turbulent (Re=104) regimes, where T and D are the distance between the centers of cylinders and the diameter of cylinders, respectively. The Reynolds number is based on the diameter of cylinders,D. The pressure field and vorticity distributions along with the associated streamlines and the time histories of hydrodynamic forces were also calculated and analyzed for different gap ratios. Generally, different flow patterns were observed as the gap ratio and Reynolds number varied. Accordingly, the hydrodynamic forces showed irregular variations for small gaps while they took a regular pattern at higher spacing ratios. | SARVGHAD-MOGHADDAM Hesam NOOREDIN Navid GHADIRI-DEHKORDI Behzad | 2011 | Journal of Hydrodynamics2011，23，6： | 7 |
| 7 | 采用上限分析方法对悬臂式挡土墙进行伪静力分析(英文)显示文摘鉴于悬臂式挡土墙在建设和开发项目中的广泛应用,合理考虑地震荷载的优化设计和分析是一个典型的工程问题。本文提出了一种利用上限法进行挡土墙拟静力分析的新算法。该算法可用于基于该机理墙体内外稳定性设计和校核。该算法的主要特点之一是能够有效地利用多目标优化,同时确定失效楔块的临界条件、作用在墙体上的最小安全系数和最大受力,以及墙体的最小重量。由所提出的失效机制所得到的结果表明,在使用上限极限分析方法时,作用力的最大化应同时考虑通过墙根后部平面方向的优化。本文还应用该算法确定了地震加速度系数的临界方向。地震加速度系数的临界方向定义为作用在墙体上的最大力方向,以保证墙体稳定的安全系数最小。本研究结果与基于极限平衡法和有限元分析的类似研究结果一致,通过遗传算法优化确定了关键失效机制。 | Asadollah RANJBAR KARKANAKI Navid GANJIAN Farajollah ASKARI | 2019 | Journal of Central South University2019，26，1： | 7 |
| 8 | An efficient correlation for calculating compressibility factor of natural gases显示文摘Compressibility factor (z-factor) values of natural gases are necessary in most petroleum engineering calculations.Necessity arises when there are few available experimental data for the required composition,pressure and temperature conditions.One of the most common methods of calculating z-factor values is empirical correlation.Firstly,a new correlation based on the famous Standing-Katz (S-K) Chart is presented to predict z-factor values.The advantage of this correlation is that it is explicit in z and thus does not require an iterative solution as is required by other methods.Secondly,the comparison between new one and other correlations is carried out and the results indicate the superiority of the new correlation over the other correlations used to calculate z-factor. | Navid Azizi Dr.R.Behbahani Dr.M.A.Isazadeh | 2010 | Journal of Natural Gas Chemistry2010，19，6： | 7 |
| 9 | Characterization of the bubbling fluidization of nanoparticles显示文摘The dynamic features of an agglomerate bubbling fluidization of nanoparticles were investigated through the analysis of pressure fluctuations.Experiments were carried out in a lab-scale fluidized bed at ambient conditions using 10-15 nm silica nanoparticles without any surface modification.Pressure fluctuation signals were processed in both frequency and time-frequency domains to characterize the behavior of various scales of phenomena(i.e.,macro-,meso-,and micro-structures) during fluidization.Due to the aggregation of nanoparticles,three separate broad peaks were observed in the frequency spectra of the pressure signals measured in the bubbling fluidized bed of nanoparticles.A non-intrusive method based on the decoupling of pressure fluctuations recorded simultaneously in the plenum and in the bed was used to determine the approximate size of the bubbles in the bed. | Mohammad R.Tamadondar Reza Zarghami Maryam Tahmasebpoor Navid Mostoufi | 2014 | Particuology2014，12，5： | 6 |
| 10 | Graphene oxide based carbon composite as adsorbent for Hg removal:Preparation, characterization, kinetics and isotherm studies显示文摘The presence of Hg in the aqueous media is known to cause severe health issues in both humans and animals.Many technologies and especially adsorbents have been applied for its removal. In this study, a graphene oxide–carbon composite(GO–CC) as a new adsorbent was prepared by sol gel procedure and characterized using field emission scanning electron microscopy, BET and EDX. The effects of different variables including solution p H, contact time, adsorbent dose and GO ratio in adsorbent matrix on the removal capacity of Hg were studied. The isotherm data correlated well with the Langmuir isotherm model. Further analysis recommended that the Hg^(2+) adsorption process is governed by the intra-particle and external mass transfer, in which the film diffusion was the rate restrictive step. The presented composite has maximum absorption capacity, q_(max) of 68.8 mg·g^(-1), which is comparable with carbon based adsorbent reported in the previous publications. | Tayebeh Esfandiyari Navid Nasirizadeh Mohammad Dehghani Mohammad Hassan Ehrampoosh | 2017 | Chinese Journal of Chemical Engineering2017，25，9： | 5 |

| 12 | Insights in hydrodynamics of bubbling fluidized beds at elevated pressure by DEM-CFD approach显示文摘A numerical simulation was conducted to study the effect of pressure on bubble dynamics in a gas-solid fluidized bed.The gas flow was modeled using the continuum theory and the solid phase,by the dis-crete element method(DEM).To validate the simulation results,calculated local pressure fluctuations were compared with corresponding experimental data of 1-mm polyethylene particles.It was shown that the model successfully predicts the hydrodynamic features of the fluidized bed as observed in the experiments.Influence of pressure on bubble rise characteristics such as bubble rise path,bubble sta- bility,average bubbles diameter and bubble velocity through the bed was investigated.The simulation results are in conformity with current hydrodynamic theories and concepts for fluidized beds at high pressures.The results show further that elevated pressure reduces bubble growth,velocity and stability and enhances bubble gyration through the bed,leading to change in bed flow structure. | Zahra Mansourpour Sedighe Karimi Reza Zarghami Navid Mostoufi Rahmat Sotudeh-Gharebagh | 2010 | Particuology2010，8，5： | 5 |
| 13 | Synthesis of a PEBAX-1074/ZnO nanocomposite membrane with improved CO_2 separation performance显示文摘In this investigation, polymeric nanocomposite membranes(PNMs) were prepared via incorporating zinc oxide(ZnO) into poly(ether-block-amide)(PEBAX-1074) polymer matrix with different loadings. The neat membrane and nanocomposite membranes were prepared via solution casting and solution blending methods, respectively. The fabricated membranes were characterized by field emission scanning electron microscopy(FESEM) to survey cross-sectional morphologies and thermal gravimetric analysis(TGA)to study thermal stability. Fourier transform infrared(FT-IR) and X-ray diffraction(XRD) analyses were also employed to identify variations of the chemical bonds and crystal structure of the membranes, respectively. Permeation of pure gases, CO_2, CH_4 and N_2 through the prepared neat and nanocomposite membranes was studied at pressures of 3–18 bar and temperature of 25 °C. The obtained results showed that the fabricated nanocomposite membranes exhibit better separation performance compared to the neat PEBAX membrane in terms of both permeability and selectivity. As an example, at temperature of 25 °C and pressure of 3 bar, CO_2 permeability, ideal CO_2/CH_4 and CO_2/N_2 selectivity values for the neat PEBAX membrane are 110.67 Barrer, 11.09 and 50.08, respectively, while those values are 152.27 Barrer,13.52 and 62.15 for PEBAX/ZnO nanocomposite membrane containing 8 wt% ZnO. | Navid Azizi Toraj Mohammadi Reza Mosayebi Behbahani | 2017 | Journal of Energy Chemistry2017，26，3： | 5 |
| 14 | Dynamics and Predictive Control of Gas Phase Propylene Polymerization in Fluidized Bed Reactors显示文摘A two-phase dynamic model,describing gas phase propylene polymerization in a fluidized bed reactor,was used to explore the dynamic behavior and process control of the polypropylene production rate and reactor temperature.The open loop analysis revealed the nonlinear behavior of the polypropylene fluidized bed reactor,justifying the use of an advanced control algorithm for efficient control of the process variables.In this case,a centralized model predictive control(MPC) technique was implemented to control the polypropylene production rate and reactor temperature by manipulating the catalyst feed rate and cooling water flow rate respectively.The corresponding MPC controller was able to track changes in the setpoint smoothly for the reactor temperature and production rate while the setpoint tracking of the conventional proportional-integral(PI) controller was oscillatory with overshoots and obvious interaction between the reactor temperature and production rate loops.The MPC was able to produce controller moves which not only were well within the specified input constraints for both control variables,but also non-aggressive and sufficiently smooth for practical implementations.Furthermore,the closed loop dynamic simulations indicated that the speed of rejecting the process disturbances for the MPC controller were also acceptable for both controlled variables. | Ahmad Shamiri Mohamed azlan Hussain Farouq sabri Mjalli Navid Mostoufi Seyedahmad Hajimolana~ | 2013 | Chinese Journal of Chemical Engineering2013，21，9： | 4 |

| 20 | Influence of glycine additive on corrosion and wear performance of electroplated trivalent chromium coating显示文摘The aim of this study is to evaluate the effect of various molar ratios of glycine to chromium salt(Gly:Cr)and different current densities on the corrosion and wear behaviors of Cr(III)electroplated coatings.The morphology and thickness of the coatings were investigated by scanning electron microscopy.The wear properties of the coatings were studied using pin on disk and hardness tests,while corrosion behavior of the coatings was identified using linear polarization,small amplitude cyclic voltammetry,and electrochemical impedance spectroscopy methods.By increasing the glycine concentration,a structure with low crack density was obtained.In all molar ratios,maximum thickness and current efficiency was observed at a current density of 150 mA·cm?2.All the electrochemical methods had a consistent result,and maximum corrosion resistance of approximately 16000Ω·cm2 was obtained in the case of Gly:Cr=3:1 and current density of 200 mA·cm?2. | Navid Mehdipour Milad Rezaei Zeynab Mahidashti | 2020 | International Journal of Minerals,Metallurgy and Materials2020，27，4： | 2 |
