| 1 | A higher order lattice BGK model for simulating some nonlinear partial differential equations显示文摘In this paper, we consider a one-dimensional nonlinear partial differential equation that has the form ut + αuux + βunux - γuxx + δuxxx = F(u). A higher order lattice Bhatnager-Gross-Krook (BGK) model with an amending-function is proposed. With the Chapman-Enskog expansion, different kinds of nonlinear partial differential equations are recovered correctly from the continuous Boltzmann equation. The numerical results show that this method is very effective. | LAI HuiLin MA ChangFeng | 2009 | Science China(Physics,Mechanics & Astronomy)2009，52，7： | 3 |
| 2 | Medical Additive Manufacturing: From a Frontier Technology to the Research and Development of Products显示文摘1.Research and development(R&D)and the challenges of raw materials for medical additive manufacturing Raw materials for medical additive manufacturing have a wide range of commonalities that are also seen in many other fields,making them an important basis in the field of three-dimensional(3D)printing.Problems and challenges related to material types,powder properties,formability,viscoelasticity,and so forth also share common features.For example,many metal materials are used in the field of aviation,while metals,polymers,and inorganic materials are used in the field of biomedicine.The most widely used materials in biomedicine are biocompatible.Various homogeneous and non-homogeneous composites are also available for 3D printing,and impose an additional challenge in additive manufacturing;the use of heterogeneous composites in 3D printing is particularly challenging. | Guixing Qiu Wenjiang Ding Wei Tian Ling Qin Yu Zhao Lianmeng Zhang Jian Lu Daijie Chen Guangyi Yuan Chengtie Wu Bingheng Lu Ruxu Du Jimin Chen Mo Elbestawi Zhongwei Gu Dichen Li Wei Sun Yuanjin Zhao Jie He Dadi Jin Bin Liu Kai Zhang Jianmo Li Kam WLeong Dewei Zhao Dingjun Hao Yingfang Ao Xuliang Deng Huilin Yang ShaoKeh Hsu Yingqi Chen Long Li Jianping Fan Guohui Nie Yun Chen Hui Zeng Wei Chen Yuxiao Lai | 2020 | Engineering2020，6，11： | 1 |

| 4 | Generation of gene-target dogs using CRISPR/Cas9 system显示文摘Dear Editor,Dogs(Canis familiaris)serve as human companions and are raised to herd livestock,aid hunters,guard homes,perform police and rescue work,and guide the blind.Dogs exhibit close similarities to humans in terms of metabolic,physiological,and anatomical characteristics,and thus are ideal genetic and clinical models to study human diseases(Tsai et al.,2007).Gene target technology is a powerful tool to create new strains of animals with favorable traits.However,thus far,gene-target dogs have not been developed due to their unique species-specific reproductive characteristics,which limits the applications of dogs especially in the field of biomedical research.Recently,clustered regularly interspaced short palindromic repeats(CRISPRs)/CRISPR-associated(Cas)9 system was applied to edit specific genes with a high efficiency(Cong et al.,2013;Mali et al.,2013).Here we attempt to explore the feasibility of producing gene knockout(KO)dogs by using this technology.Beagle dog,the most widely used breed in biomedical research,was used as our animal model.Myostatin(MSTN)was chosen as the first gene of interest. | Qingjian Zou Xiaomin Wang Yunzhong Liu Zhen Ouyang Haibin Long Shu Wei Jige Xin Bentian Zhao Sisi Lai Jun Shen Qingchun Ni Huaqiang Yang Huilin Zhong Li Li Minhua Hu Quanjun Zhang Zhidong Zhou Jiaxin He Quanmei Yan Nana Fan Yu Zhao Zhaoming Liu Lin Guo Jiao Huang Guanguan Zhang Jun Ying Liangxue Lai Xiang Gao | 2015 | Journal of Molecular Cell Biology2015，7，6： | 1 |
| 5 | Enhanced Anomalous Hall Effect of Pt on an Antiferromagnetic Insulator with Fully Compensated Surface显示文摘We report a significantly enhanced anomalous Hall effect(AHE)of Pt on antiferromagnetic insulator thin film(3-unit-cell La_(0.7)Sr_(0.3)MnO_(3),abbreviated as LSMO),which is one order of magnitude larger than that of Pt on other ferromagnetic(e.g.Y_(3)Fe_(5)O_(12))and antiferromagnetic(e.g.Cr_(2)O_(3))insulator thin films.Our experiments demonstrate that the antiferromagnetic La_(0.7)Sr_(0.3)MnO_(3)with fully compensated surface suppresses the positive anomalous Hall resistivity induced by the magnetic proximity effect and facilitates the negative anomalous Hall resistivity induced by the spin Hall effect.By changing the substrate’s temperature during Pt deposition,we observed that the diffusion of Mn atoms into Pt layer can further enhance the AHE.The anomalous Hall resistivity increases with increasing temperature and persists even well above the Neel temperature(T_(N))of LSMO.The Monte Carlo simulations manifest that the unusual rise of anomalous Hall resistivity above T_(N)originates from the thermal induced magnetization in the antiferromagnetic insulator. | Yu Bai Zhe Wang Na Lei Wisal Muhammad Lifeng Xiang Qiang Li Huilin Lai Yinyan Zhu Wenbing Wang Hangwen Guo Lifeng Yin Ruqian Wu Jian Shen | 2022 | Chinese Physics Letters2022，39，10： | 0 |
| 6 | Influence of the tangential velocity on the compressible Kelvin–Helmholtz instability with nonequilibrium effects显示文摘Kelvin–Helmholtz(KH)instability is a fundamental fluid instability that widely exists in nature and engineering.To better understand the dynamic process of the KH instability,the influence of the tangential velocity on the compressible KH instability is investigated by using the discrete Boltzmann method based on the nonequilibrium statistical physics.Both hydrodynamic and thermodynamic nonequilibrium(TNE)effects are probed and analyzed.It is found that,on the whole,the global density gradients,the TNE strength and area firstly increase and decrease afterwards.Both the global density gradient and heat flux intensity in the vertical direction are almost constant in the initial stage before a vortex forms.Moreover,with the increase of the tangential velocity,the KH instability evolves faster,hence the global density gradients,the TNE strength and area increase in the initial stage and achieve their peak earlier,and their maxima are higher for a larger tangential velocity.Physically,there are several competitive mechanisms in the evolution of the KH instability.(i)The physical gradients increase and the TNE effects are strengthened as the interface is elongated.The local physical gradients decrease and the local TNE intensity is weakened on account of the dissipation and/or diffusion.(ii)The global heat flux intensity is promoted when the physical gradients increase.As the contact area expands,the heat exchange is enhanced and the global heat flux intensity increases.(iii)The global TNE intensity reduces with the decreasing of physical gradients and increase with the increasing of TNE area.(iv)The nonequilibrium area increases as the fluid interface is elongated and is widened because of the dissipation and/or diffusion. | Yaofeng Li Huilin Lai Chuandong Lin Demei Li | 2022 | Frontiers of physics2022，17，6： | 0 |
