INITIAL BOUNDARY VALUE PROBLEM FOR A NONCONSERVATIVE SYSTEM IN ELASTODYNAMICS

Acta Mathematica Scientia 2018年第3期38卷 1043-1056页

This article is concerned with the initial boundary value problem for a nonconservative system of hyperbolic equation appearing in elastodynamics in the space time domain x 〉 0, t 〉 0. The number of boundary conditions, to be prescribed at the boundary x = 0,depends on the number of characteristics entering the domain. Because our system is nonlinear, the characteristic speeds depends on the unknown and the direction of the characteristics curves are known apriori. As it is well known, the boundary condition has to be understood in a generalised way. One of the standard way is using vanishing viscosity method. We use this method to construct solution for a particular class of initial and boundary data, namely the initial and boundary datas that lie on the level sets of one of the Riemann invariants.

数百万人受呼吸系统疾病的影响,导致巨大的全球性健康困扰。由于目前对导致呼吸系统疾病发展和进展的潜在机制认识不足,治疗选择仍然有限。为克服此局限和理解相关分子变化,将无创影像技术如PET和SPECT用于探索生物标志物,其中18F-脱氧葡萄糖(FDG)PET显像的研究最多。由于肺内组织、气体、血液和水的构成比变异,定量分析肺的分子影像数据仍具挑战性。这些成分的比例随着肺部疾病的不同而不同,因此有不同的定量分析方法来显示这种变化,但迄今为止还没有开发出对数据标准化的方法。该文回顾了肺部疾病中18F-FDG PET定量分析方法的数据,聚焦于解释肺内成分变化的方法,解读衍生参数。分析的疾病包括急性呼吸窘迫综合征、慢性阻塞性肺疾病、肺间质性疾病如特发性肺纤维化。基于对既往文献、进行中的研究以及作者间讨论的回顾,作者提出了建议性的注意事项,以协助解读从这些方法及未来研究设计中衍生的参数。
