Optimal Control in Heterogeneous Domain Decomposition Methods for Advection-Diffusion Equations

New domain decomposition methods (DDM) based on optimal control approach are introduced for the coupling of first and second order equations on overlapping subdomains. Several cost functionals and control functions are proposed. Uniqueness and existence results are proved for the coupled problem, and the convergence of iterative processes is analyzed. The work was supported by the Russian Foundation for Basic Research (04-01-00615) and it was partly carried out while the first author was visiting the IACS at EPFL.     

人的全面发展观与学生党支部建设

“人的全面发展”观是马克思主义人学理论中的一个基本观点。全面发展的人是社会现代化的构成和目标，促进人的全面发展是社会主义现代化事业的目标和任务。高校学生党支部要按照人的全面发展的观点，调整党支部的工作思路，改进党支部的内部管理，形成充满活力的运行机制，使学生党支部真正成为高校学生中党的工作的主阵地。     

鼻咽癌的角蛋白-粘液组化观察

作者采用同时显示角蛋白和粘液的PAP和ABC免疫组化染色法观察了14例经石蜡包埋的鼻咽癌组织切片,初步结果如下: 1.鼻咽柱状细胞和单纯化生的鳞状细胞均含人体角蛋白.当细胞的核呈异型性变时,角蛋白含量明显减少. 2.鼻咽分化差的鳞癌细胞一般含有角蛋白,虽然各个癌细胞之间含量有差异,但如果采用8型和18型单克隆抗体时,则情况有所不同,一些癌细胞呈阳性而另一些癌细胞则为阴性. 3.在呈异型性变的上皮中仍可找到少数几个粘液细胞,但在癌巢中却未见有粘液细胞. 本文讨论了上述结果在鼻咽癌组织发生学中的意义.     

Reconstruction of the Point-Spread Function of the Human Eye Using a New Phase-Retrieval Algorithm

The double-pass method is thought to obtain the point spread function (PSF) in human eyes based on two techniques: the symmetric double-pass method using the same pupil size and the asymmetric double-pass method using a different pupil size. The symmetric double-pass method provides autocorrelation of the retinal PSF and, thus, the modulation transfer function. The asymmetric double-pass method provides low-frequency partial-phase information and the partial phase-retrieval algorithm is applied to obtain the complete-phase information, and to estimate the PSF. The partial phase-retrieval algorithm is based on the iteration method proposed by Fineup and Kowalczyk and requires a lengthy computation. In this study, we propose a new high-speed phase-retrieval algorithm based on the property that the real and imaginary parts of optical transfer functions (OTFs) continuously change in value.     

On the genericity of chaos

Let M be a compact manifold with dimM?2. We prove that some iteration of the generic homeomorphism on M is semiconjugated to the shift map and has infinite topological entropy (Theorem 1.1).     

Tropical Weyl Group Action via Point Configurations and τ-Functions of the q-Painlevé Equations

Starting from certain point sets in the projective plane, we construct a tropical (or subtraction-free birational) representation of Weyl groups over the field of τ-functions. In particular, our construction includes E ₈ ⁽¹⁾ , E ₇ ⁽¹⁾ , E ₆ ⁽¹⁾ and D ₅ ⁽¹⁾ as affine cases; each of them gives rise to the q-difference Painlevé equation.
