1Some theoretical aspects of elastic wave modeling with a recently developed spectral element method显示文摘A spectral element method has been recently developed for solving elastodynamic problems. The numerical solutions are obtained by using the weak formulation of the elastodynamic equation for heterogeneous media, based on the Galerkin approach applied to a partition, in small subdomains, of the original physical domain. In this work, some mathematical aspects of the method and the associated algorithm implementation are systematically investigated. Two kinds of orthogonal basis functions, constructed with Legendre and Chebyshev polynomials, and their related Gauss-Lobatto collocation points are introduced. The related integration formulas are obtained. The standard error estimations and expansion convergence are discussed. An element-by-element pre-conditioned conjugate gradient linear solver in the space domain and a staggered predictor/multi-corrector algorithm in the time integration are used for strong heterogeneous elastic media. As a consequence, neither the global matrices nor the effective force vector is assembled. When analytical formulas are used for the element quadrature, there is even no need for forming element matrix in order to further save memory without losing much in computational efficiency. The element-by-element algorithm uses an optimal tensor product scheme which makes this method much more efficient than finite-element methods from the point of view of both memory storage and computational time requirements. This work is divided into two parts. The first part mainly focuses on theoretical studies with a simple numerical result for the Che-byshev spectral element, and the second part, mainly with the Legendre spectral element, will give the algorithm implementation, numerical accuracy and efficiency analyses, and then the detailed modeling example comparisons of the proposed spectral element method with a pseudo-spectral method, which will be seen in another work by Lin, Wang and Zhang.SERIANI Geza 2007Science China(Physics,Mechanics & Astronomy)2007,50,2:7

3妊娠期和哺乳期患者的口腔卫生保健显示文摘妊娠期和哺乳期患者为口腔卫生保健工作者提出了一系列独特的管理问题。临床医师有责任为妊娠母亲提供安全有效地护理.同时应考虑到胎儿或者新生儿的安全。还要考虑到药物的影响.有些药物能从母体的血浆通过胎盘扩散到胎儿体内.或者分布到乳汁中,达到潜在的危险浓度.影响母乳喂养的婴儿。另外,有些母亲口腔状况的改变,可能是妊娠期一系列生理改变的结果.这些改变需要引起口腔医师关注。考虑到临床口腔医师在诊治妊娠期或哺乳期患者时要负的双重责任.因此熟悉妊娠生理学.胎儿的发育过程。Susan E.

5Widely tunable,heterogeneously integrated quantum-dot O-band lasers on silicon显示文摘Heterogeneously integrated lasers in the O-band are a key component in realizring low-power optical interconnects for data centers and high-performance computing.Quantum-dot-based materials have been particularly appealing for light generation due to their ultralow lasing thresholds,small linewidth enhancement factor,and low sensitivity to reflections.Here,we present widely tunable quantum-dot lasers heterogencously integrated on silicon-on-insulator substrate.The tuning mechanism is based on Vernier dual-ring geometry,and a 47nm tuning range with 52 dB side-mode suppression ratio is observed.These parameters show an increase to 52nm and 58 dB,respectively,when an additional wavelength filter in the form of a Mach-Zehnder interferometer is added to the cavity.The Lorentzian linewidth of the lasers is measured as low as 5.3 kHz.ADITYA MALIK JOEL GUO MINH A.TRAN GEZA KURCZVEIL DI LIAN JOHN EBOWERS 2020Photonics Research2020,8,10:4
