海洋碎屑沉积物的粒度特征是海底沉积动力环境的直接体现,是用来研究海洋动力环境变化的重要手段,尤其是陆架海底表层沉积物的粒度分布,对于研究沿岸和水柱底边界层现今海洋动力环境可起到重要作用。该项研究通过调查遍布泰国湾至湄公河口海底表层沉积物陆源碎屑的粒度分布特征,以期获得影响现今特定海域沉积作用的海洋动力环境过程。粒度分析的结果显示,泰国湾表层沉积物的陆源碎屑以细砂-细粉砂为主,分选总体较差,频率分布以正偏为主。其中,细砂-极细砂组分主要分布在曼谷湾和柬埔寨沿岸。湄公河岸外沉积物为细砂,且分选比泰国湾区域的沉积物要好。这些表层沉积物的粒度特征具有良好的环境变化指示作用。湄公河岸外分选较好、近于正态分布的中砂沉积物指示了波浪作用下的沉积环境。曼谷湾和柬埔寨沿岸分选较差的中砂-细砂粗粒沉积物反映了潮汐和波浪的共同作用;泰国湾东西沿岸区域分选中等、呈正偏态的极细砂-中粉砂沉积物体现了潮汐的控制作用;而泰国湾中部分选较差的沉积物则指示了表层洋流作用。研究表明,泰国湾和湄公河岸外表层沉积物陆源碎屑的粒度分布特征可用于区分不同海洋动力因素的控制作用,揭示出泰国湾的沉积动力环境主要受潮汐、波浪和洋流的共同影响,湄公河岸外的沉积动力环境主要受波浪的影响。

H^2-Stabilization of the Isothermal Euler Equations: a Lyapunov Function Approach

引用

Chinese Annals of Mathematics,Series B 2012年第4期33卷 479-500页

作者： martin gUgAT günter LEUgERINg Simona TAMASOIU Department of Mathematics Friedrich-Alexander University Erlangen-Nuremberg Cauerstrasse 11 91058 Erlangen Germany

The authors consider the problem of boundary feedback stabilization of the 1D Euler gas dynamics locally around stationary states and prove the exponential stability with respect to the H^2-norm. To this end, an explicit Lyapunov function as a weighted and squared H^2-norm of a small perturbation of the stationary solution is constructed. The authors show that by a suitable choice of the boundary feedback conditions, the H^2-exponential stability of the stationary solution follows. Due to this fact, the system is stabilized over an infinite time interval. Furthermore, exponential estimates for the C^1-norm are derived.

Objective: Striatins(STRNs) family, which contains three multi-domain scaffolding proteins, are cornerstones of the striatins interacting phosphatase and kinase(STRIPAK) complex. Although the role of the STRIPAK complex in cancer has become recognized in recent years, its clinical significance in breast cancer has not been fully ***: Using a freshly frozen breast cancer tissue cohort containing both cancerous and adjacent normal mammary tissues, we quantitatively evaluated the transcript-level expression of all members within the STRIPAK complex along with some key interacting and regulatory proteins of STRNs. The expression profile of each molecule and the integrated pattern of the complex members were assessed against the clinical-pathological factors of the patients. The Cancer genome Atlas(TCgA) dataset was used to evaluate the breast cancer patients’ response to chemotherapies. Four human breast cancer cell lines, MDA-MB-231, MDA-MB-361, MCF-7, and SKBR-3, were subsequently adopted for in vitro ***: Here we found that high-level expressions of STRIP2, calmodulin, CCM3, MINK1 and SLMAP were respectively associated with shorter overall survival(OS) of patients. Although the similar pattern observed for STRN3, STRN4 and a contrary pattern observed for PPP2CA, PPP2CB and PPPR1A were not significant, the integrated expression profile of STRNs group and PPP2 group members constitutes a highly significant prognostic indicator for OS [Pgical functions including adhesiveness and migration. In line with our clinical findings, the breast cancer cells responded to STRN3 knockdown with changes in their chemo-sensitivity, of which the response is also breast cancer subtype ***: Our results suggest a possible role of the STRIPAK complex
