Parametric simulation of electron backscatter diffraction patterns through generative models

npj Computational Materials 2023年第1期9卷 285-294页

作者： Zihao Ding marc.de graef department of Materials Science and Engineering Carnegie Mellon UniversityPittsburghPA 15213USA

Recently,discriminative machine learning models have been widely used to predict various attributes from Electron Backscatter Diffraction(EBSD)***,there has never been any generative model developed for EBSD pattern *** one hand,the training of generative models is much harder than that of discriminative ones;On the other hand,numerous variables affecting EBSD pattern formation make the input space high-dimensional and its relationship with the distribution of backscattered electrons *** this study,we propose a framework(EBSD-CVAE/GAN)with great flexibility and scalability to realize parametric simulation of EBSD *** with the frequently used forward model,EBSD-CVAE/GAN can take variables more than just orientation and generate corresponding EBSD patterns in a single *** accuracy and quality of generated patterns are systematically *** model does not only summarize a distribution of backscattered electrons at a higher level,but also mitigates data scarcity in this field.

该书是一本自成一体的教材，涵盖了晶体学、对称性和衍射的基本知识，陈述严格并易于阅读。侧重于结合晶体结构的可视化插图和晶体学的数学理论来理解各种材料的复杂性。本书的上半部分系统地描述了晶体学的基础知识，讨论了化学键、晶体体系、对称性、点群和衍射的概念。下半部分内容则更加前沿，阐述了如何通过测定物质结构来研究各种材料，如金属、陶瓷、共价键、无定形、分子固体和纳米材料。并且还介绍了晶体学的几何原理和计算技术。

To assess the peripheral refractive changes that occur when eye growth decelerates in *** We measured peripheral refraction and on-axis vitreous chamber depth on a total of 53 marmosets;36 treated monocularly for 12 weeks 9 hrs/day(26 with-5 D contact lenses,10 with+5 D)and 17 untreated *** the 26 marmosets treated with-5 D,10 wore contact lenses 9 hrs/day without interruptions and were mea-sured at the end of 10 weeks of treatment(T10)and after 4 weeks of recovery(R14).Eight had both contact lenses removed for 30 mins twice/day(mid-morning and mid-afternoon)during the first four weeks of treatment(early interruption group)and eight had the lenses removed during the second four weeks of treatment(late interruption group).The two interruption groups were measured after 4,8 and 12 weeks of treatment only(T4,T8,T12).
