Wave Damping and Refraction-Diffraction Due to Variable Depth Porous Bottom

The refraction-diffraction of surface waves due to porous variable depth has been the subject of many investigations. In the present study, we extend the boundary-value problem of impermeable varying topography to that of a variable depth porous seabed, which is the situation most likely to be encountered in practical problems of coastal engineering. A wave-induced fluid motion is applied to the porous bottom, while the well-known linear potential theory is applied to the free-water above the bottom. Eigenfunction expansions are employed to derive the matching condition and the so-caUed modified dispersion relation. As a result of the porous bottom, the wavenumber becomes a complex value, of which the real part represents the spatial periodicity while the imaginary part refers to the energy dissipation. The characteristics of water waves over a porous bottom are studied in detail. By neglecting the non-propagating modes which only have a local effect and damp exponentially with distance, we derive a mathematical model to represent the characteristics of both the wave refraction-diffraction and wave-damping. The developed model is applied to the damping problem of waves over submerged porous breakwaters.     

胸导管结扎对胰淀肽沉积及胰岛激素和糖代谢的影响

采用腹部结扎大鼠胸导管,建立胰淋巴瘀滞动物模型,观察实验动物胰组织结构的变化和胰淀肽沉积情况,探讨胰淋巴瘀滞对胰岛激素和糖代谢的影响.30只10月龄SD大鼠随机分为实验组和对照组;造模后6个月取胰组织标本,经石蜡包埋和切片,常规HE和刚果红染色,冰冻切片胰淀肽免疫组织化学染色后光镜观察;在胸导管结扎前、后及实验动物处死前,分别取静脉血测血糖、胰岛素和C-肽.结果显示:1)实验组动物胰组织切片的HE和刚果红染色光镜观察显示,胰腺小叶和胰岛的组织间隙明显增宽,而且胰岛普遍表现为朱红色刚果红着色现象;2)胰淀肽免疫组织化学染色切片的光镜观察表明,在实验组动物的胰岛及其周围,普遍呈现胰淀肽免疫反应强阳性棕褐色着色反应;3)实验组大鼠术后血糖明显升高,血清胰岛素水平下降,与对照组相比差异显著,然而C-肽水平的变化不明显.胰组织结构的变化提示,结扎胸导管可导致胰淋巴引流障碍、胰腺内脂肪堆积、胰岛及其周围胰淀肽沉积、胰岛细胞功能受损、血中胰岛素浓度下降和血糖水平升高.

A Method to Implement Full Anonymous Attestation for Trusted Computing Platform

Trusted computing （TC） technology is brought out by trusted computing group （TCG） to make computing as safe and reliable as people expect. Attestation is one main function specified by TCG, which is the means by which a trusted computer assures a remote computer whose platform is not tampered with. There are two protocols that implement attestation without disclosing the platform＇s real identity, which are Privacy CA-based protocol and direct anonymous attestation （DAA） protocol. However, in the first protocol the privacy CA is the bottleneck and the platform＇s identity will be disclosed if the privacy CA is compromise, while DAA protocol can do profiling when dealing with rogue hardware device. In this paper, we propose a DAA-extended new approach to ensure full anonymous attestation that can not only detect a rogue TPM, but also reveal rogue TPM＇s real identity.
