| 2 | New Bivalved Arthropods from the Cambrian(Series 3, Drumian Stage) of Western Hunan, South China显示文摘We report two new three-dimensionally phosphatized microfossils, Cambrolongispina reticulata gen. et sp. nov. and Cambrolongispina glabra gen. et sp. nov., from the middle Cambrian(Series 3, Drumian Stage) at Wangcun, Yongshun County, western Hunan, South China. They are bivalved arthropods, with thin, pliable, originally chitinous or chitin-calcareous shields(c. 350–517μm long). The shields are equipped with a pair of antero-dorsal spines. The spines are internally hollow, varying in length from 1/2 of to as long as the shield length in C. reticulata, and uniformly longer than the shield length in C. glabra. The spines of C. reticulata are ornamented with a longitudinal row of conical or blade-shaped denticles along the posterior edge. Cambrolongispina lacks marginal rims, valve lobation and sulci which are diagnostic of the Bradoriida sensu stricto. It also lacks a doublure/duplicature characteristic of phosphatocopids and some bradoriids. It could be related to the Monasteriidae(which may belong to Bradoriida sensu lato), both characterized by a pair of antero-dorsal spines. Cambrolongispina may have been meiofaunal detritus feeders that lived on or within sediments. The antero-dorsal spines may have been sensory organs to detect nearby predators. The posterior denticles on these spines might have facilitated the sensory function of the spines. | ZHANG Huaqiao DONG Xi-ping XIAO Shuhai | 2014 | Acta Geologica Sinica(English Edition)2014，88，5： | 7 |
| 3 | A brief review on the convergence to steady state solutions of Euler equations with high-order WENO schemes显示文摘Weighted essentially non-oscillatory(WENO)schemes are a class of high-order shock capturing schemes which have been designed and applied to solve many fluid dynamics problems to study the detailed flow structures and their evolutions.However,like many other high-order shock capturing schemes,WENO schemes also suffer from the problem that it can not easily converge to a steady state solution if there is a strong shock wave.This is a long-standing difficulty for high-order shock capturing schemes.In recent years,this non-convergence problem has been studied extensively for WENO schemes.Numerical tests show that the key reason of the non-convergence to steady state is the slight post shock oscillations,which are at the small local truncation error level but prevent the residue to settle down to machine zero.Several strategies have been proposed to reduce these slight post shock oscillations,including the design of new smoothness indicators for the fifth-order WENO scheme,the development of a high-order weighted interpolation in the procedure of the local characteristic projection for WENO schemes of higher order of accuracy,and the design of a new type of WENO schemes.With these strategies,the convergence to steady states is improved significantly.Moreover,the strategies are applicable to other types of weighted schemes.In this paper,we give a brief review on the topic of convergence to steady state solutions for WENO schemes applied to Euler equations. | Shuhai Zhang Jun Zhu Chi-Wang Shu | 2019 | Advances in Aerodynamics2019，1，1： | 6 |

| 5 | Study of lubrication behavior of pure water for hydrophobic friction pair显示文摘The perfluorooctyltrichlorosilane molecular layer was self-assembled on glass plate. The tribological properties of the molecular layer in water were studied with the method of ball on disk. An interesting phenomenon was found that low friction coefficients of 0.02―0.08 were obtained when the friction pair was lubricated with only a water droplet. Whereas, when the friction pair was encircled with large amount of water or fully immersed in water, the friction coefficient was higher than that under a droplet lubrication. A mechanism of water droplet lubrication was proposed that the surface tension caused by the solid-liquid-air three-phase interface makes water molecules enter into the contact zone, which separates the two friction surfaces and provides a low friction coefficient. However, water film can hardly form when more water encircles the friction pair, due to the attraction between water molecules. | MA ZhiZuo ZHANG ChenHui LIU ShuHai LUO JianBin LU XinChun WEN ShiZhu | 2009 | Science China(Technological Sciences)2009，52，11： | 4 |

| 8 | Sliding friction of shale rock on dry quartz sand particles显示文摘The sliding friction of rock, involving all kinds of particles at the contact surface, is relevant to many problems, ranging from those in artificial engineering to earthquake dynamics. In this work, the frictional performance of the shale rock–dry quartz sand contact was investigated using a self-developed testing device. The study showed that the coefficient of friction of the contact increases with nominal stress and that the corresponding friction force increases approximately linearly with nominal stress, which is directly related to the contact stress between each single sand particle and rock shale. An overall dynamic coefficient, γ, reflecting the response of friction force to nominal stress, first decreases and then increases with area ratio, which is determined by not only the contact stress but also the interparticle friction force. These have important repercussions for a preliminary understanding of the frictional properties of the shale rock–dry quartz sand contact in hydraulic fracturing and related industrial applications. | Huijie ZHANG Shuhai LIU Huaping XIAO | 2019 | Friction2019，7，4： | 2 |
| 9 | Mitochondrial and nuclear changes in hippocampal neurons in a lithium-pilocarpine-induced status epilepticus rat model显示文摘BACKGROUND:Mitochondrial damage plays a key role in neuronal damage. OBJECTIVE:To observe ultrastructural damage to mitochondria and nuclei,as well as caspase-3 expression,in hippocampal CA3 neurons of lithium-pilocarpine-induced status epilepticus rats. DESIGN,TIME AND SETTING:The neuropathological,randomized,controlled study was performed at the Animal Experimental Center,Shandong University,China in May 2008. MATERIALS:A total of 75 healthy,adult,male,Wistar rats were randomly assigned into model (n = 45) and control(n = 30) groups.Lithium-pilocarpine(Sigma,USA) was used in this study. METHODS:Rats in the model group were intraperitoneally injected with lithium chloride(3 mEq/kg), and 24 hours later with pilocarpine(45 mg/kg),to induce seizures for 2 hours.Rats in the control group were intraperitoneally infused with the same volume of saline.Rat hippocampal CA3 tissue was obtained at 3,12,and 24 hours following status epilepticus. MAIN OUTCOME MEASURES:Neuronal changes were observed under an optical microscope. Ultrastructural changes in mitochondria and nuclei were observed using an electron microscope. caspase-3 mRNA levels were quantified by semiquantitative RT-PCR. RESULTS:After 3 hours of status epilepticus,mitochondria with swollen cristae and ruptured membranes were observed by electron microscopy.Nuclei with marginated chromatin were observed after 24 hours status epilepticus.RT-PCR results demonstrated increased caspase-3 expression at 12 hours,and significantly increased expression at 24 hours following termination of status epilepticus.This was in accordance with acidophilia occurrence,as indicated by hematoxylin-eosin staining,and time of ultrastructural damage to nuclei. CONCLUSION:In lithium-pilocarpine-induced status epilepticus rat models,ultrastructural damage to mitochondria in hippocampal neurons occurred during early stages,followed by increased caspase-3 expression and nuclear changes.These results suggested that mitochondrial damage plays a key role in neuronal damage following status epilepticus. | Shuhai Tang Li Zhang Jianying Sun Xiaojun Pan | 2009 | Neural Regeneration Research2009，4，3： | 2 |
| 10 | Shear of molecular deposition films on glass substrates determined by tribometer显示文摘The ultrathin polyelectrolyte molecular deposition films and polyelectrolyte composite nanoparticles molecular deposition films were prepared using layer-by-layer molecular deposition method and in situ growth method.A micro-tribometer has been developed to measure the shear response of those ultrathin molecular deposition films.By using a smooth steel sphere in a ball-on-flat configuration,the shear force was determined for molecular deposition films on glass substrate for different layers.The results indicate that the shear behaviors of molecular deposition film were mainly determined with the contact area and film layers.Moreover,the composite molecular deposition film with nanoparticles has better shear behaviors than the polyelectrolyte molecular deposition film.The shear force of polyelectrolyte molecular deposition film is more dependent on the speed than that of composite nanoparticle molecular deposition film. | GUO YanBao WANG DeGuo LIU ShuHai ZHANG SiWei | 2011 | Science China(Technological Sciences)2011，54，4： | 2 |
| 11 | A Lagrangian criterion of unsteady flow separation for two-dimensional periodic flows显示文摘The present paper proposes a Lagrangian criterion of unsteady flow separation for two-dimensional periodic flows based on the principle of weighted averaging zero skin-friction given by Haller(HALLER, G. Exact theory of unsteady separation for two-dimensional flows. Journal of Fluid Mechanics, 512, 257–311(2004)). By analyzing the distribution of the finite-time Lyapunov exponent(FTLE) along the no-slip wall, it can be found that the periodic separation takes place at the point of the zero FTLE.This new criterion is verified with an analytical solution of the separation bubble and a numerical simulation of lid-driven cavity flows. | Shuaibin HAN Shuhai ZHANG Hanxin ZHANG | 2018 | Applied Mathematics and Mechanics(English Edition)2018，39，7： | 2 |

| 17 | Numerical simulation of a complex moving rigid body under the impingement of a shock wave in 3D显示文摘In this paper,we take a numerical simulation of a complex moving rigid body under the impingement of a shock wave in three-dimensional space.Both compressible inviscid fluid and viscous fluid are considered with suitable boundary conditions.We develop a high order numerical boundary treatment for the complex moving geometries based on finite difference methods on fixed Cartesian meshes.The method is an extension of the inverse Lax-Wendroff(ILW)procedure in our works(Cheng et al.,Appl Math Mech(Engl Ed)42:841-854,2021;Liu et al.)for 2D problems.Different from the 2D case,the local coordinate rotation in 3D required in the ILW procedure is not unique.We give a theoretical analysis to show that the boundary treatment is independent of the choice of the rotation,ensuring the method is feasible and valid.Both translation and rotation of the body are taken into account in this paper.In particular,we reformulate the material derivative for inviscid fluid on the moving boundary with no-penetration condition,which plays a key role in the proposed algorithm.Numerical simulations on the cylinder and sphere are given,demonstrating the good performance of our numerical boundary treatments. | Shihao Liu Ziqiang Cheng Yan Jiang Jianfang Lu Mengping Zhang Shuhai Zhang | 2022 | Advances in Aerodynamics2022，4，1： | 1 |
