| 1 | 载瘤动脉壁剪切力作为独立变量在前交通动脉动脉瘤形成中的作用显示文摘目的本研究旨在确定哪些血流动力学参数可以独立影响前交通动脉(AcomA)动脉瘤形成,并探讨母动脉壁剪切力(WSS)的阈值,以更好地证明WSS大小与AcomA动脉瘤形成之间的相关性。 | X.Zhang Z.Q.Yao T.Karuna X.Y.He X.M.Wang X.F.Li 徐晶(译) 陈秀玉(校) | 2019 | 国际医学放射学杂志2019，0，2： | 15 |
| 2 | 中元古代具有高的Cr同位素分异特征和高的大气氧浓度显示文摘大气氧对生命大爆发具有重要意义。然而。前人通过Cr同位素研究表明,中元古代时期具有非常低的大气氧浓度(当今氧水平的0.1%),并不足以使得中元古代真核生物大爆发。Cr同位素是揭示大气氧化历史的一个非常有用的办法。由于Cr^3+物相发生大陆氧化性风化作用,Cr同位素会发生分馏,重的53Cr同位素会倾向于进入氧化的镉酸盐中(Cr^4+),从而使得残留相(Cr^3+)中亏损重Cr同位素。 | D.E.Canfield S.C.Zhang A.B.Frank X.M.Wang H.J.Wang J.Su Y.T.Ye R.Frei 袁超 | 2018 | 矿物岩石地球化学通报2018，37，6： | 5 |
| 3 | Processing, Microstructure and Mechanical Properties of Ti6Al4V Particles-Reinforced Mg Matrix Composites显示文摘Novel Ti6Al4V particles-reinforced AZ91 Mg matrix composites were successfully fabricated by stir casting method. The stirring time in semisolid condition directly affected the particle distribution and the quality of the ingots.Furthermore, the optimal speed of the heating and the liquid stirring could overcome particle settlement caused by the density difference between the matrix and the particles. Ti6Al4V particles distributed uniformly in the composites with different particle contents. The average grain size decreased with the increase in the particle contents. The Ti6Al4V particles bonded pretty well with the alloy matrix. In addition, there were some interfacial reactions in the composites.There were rod-like Al_3Ti phases at the interface. The precipitates extended from the particle surface to the matrix, and they might improve the interfacial bonding strength. The ultimate tensile strength, yield strength and elastic modulus were enhanced as the particle contents increased, and the elongation was much better than that of the same matrix material reinforced with SiC particles. Thus, the novel composites exhibit better comprehensive mechanical properties. | X.M.Wang X.J.Wang X.S.Hu K.Wu M.Y.Zheng | 2016 | Acta Metallurgica Sinica(English Letters)2016，29，10： | 5 |
| 4 | A tabletop, ultrashort pulse photoneutron source driven by electrons from laser wakefield acceleration显示文摘Relativistic electron beams driven by laser wakefield acceleration were utilized to produce ultrashort neutron sources.The experiment was carried out on the 38 fs,~0.5 J,800 nm Ti:Sapphire laser in the 10 TW UT 3 laser lab at University of Texas at Austin.The target gas was a high density pulsed gas jet composed of 90%He and 10%N 2.The laser pulse with a peak intensity of 1.5×10^(18) W/cm^(2) interacted with the target to create a cylindrical plasma channel of 60 mm radius(FWHM)and 1.5 mm length(FWHM).Electron beams of~80 pC with the Gaussian energy distribution centered at 37 MeV and a width of 30 MeV(FWHM)were produced via laser wakefield acceleration.Neutron fluences of~2.4×10^(6) per shot with hundreds of ps temporal length were generated through bremsstrahlung and subsequent photoneutron reactions in a 26.6 mm thick tungsten converter.Results were compared with those of simulations using EPOCH and GEANT4,showing agreement in electron spectrum,neutron fluence,neutron angular distribution and conversion rate. | X.J.Jiao J.M.Shaw T.Wang X.M.Wang H.Tsai P.Poth I.Pomerantz L.A.Labun T.Toncian M.C.Downer B.M.Hegelich | 2017 | Matter and Radiation at Extremes2017，2，6： | 1 |
| 5 | Machine learning guided automatic recognition of crystal boundaries in bainitic/martensitic alloy and relationship between boundary types and ductile-to-brittle transition behavior显示文摘Gradient boosting decision tree(GBDT)machine learning(ML)method was adopted for the first time to automatically recognize and conduct quantitative statistical analysis of boundaries in bainitic microstructure using electron back-scatter diffraction(EBSD)data.In spite of lack of large sets of EBSD data,we were successful in achieving the desired accuracy and accomplishing the objective of recognizing the boundaries.Compared with a low model accuracy of<50%as using Euler angles or axis-angle pair as characteristic features,the accuracy of the model was significantly enhanced to about 88%when the Euler angle was converted to overall misorientation angle(OMA)and specific misorientation angle(SMA)and considered as important features.In this model,the recall score of prior austenite grain(PAG)boundary was~93%,high angle packet boundary(OMA>40°)was~97%,and block boundary was~96%.The derived outcomes of ML were used to obtain insights into the ductile-to-brittle transition(DBTT)behavior.Interestingly,ML modeling approach suggested that DBTT was not determined by the density of high angle grain boundaries,but significantly influenced by the density of PAG and packet boundaries.The study underscores that ML has a great potential in detailed recognition of complex multi-hierarchical microstructure such as bainite and martensite and relates to material performance. | X.C.Li J.X.Zhao J.H.Cong R.D.K.Misra X.M.Wang X.L.Wang C.J.Shang | 2021 | Journal of Materials Science & Technology2021，，25： | 1 |
