Escrowable identity-based authenticated key agreement(AKA) protocols are desirable under certain circumstances especially in certain closed groups *** this paper,we focus on two-party identitybased AKA schemes in the escrow mode,and present a strongly secure escrowable identity-based AKA protocol which captures all basic desirable security properties including perfect forward secrecy,ephemeral secrets reveal resistance and so *** protocol is provably secure in the extended Canetti-Krawczyk model,and its security can be reduced to the standard computational bilinear Diffie-Hellman assumption in the random oracle *** no adversary can obtain the master private key for the escrow mode,our scheme is secure as long as each party has at least one uncompromised ***,we present two strongly secure variants of the protocol,which are computationally more efficient than the original scheme.

Background Epidemiological studies have shown that both active and passive cigarette smoking increase the risk of atherosclerosis. But very little is known about the biological processes induced by passive cigarette smoking that contribute to atherosclerosis. We observe the expression of a few of biological and inflammatory markers in human arterial walls in vitro which were treated with the second-hand smoke solution （sidestream whole, SSW）, and discuss the possible mechanism of inflammatory injury induced by second-hand smoke. Methods The biological markers （platelet endothelial cell adhesion molecule-I, PECAM-1; a-smooth muscle actin, a-SMA; collagen IV, Col IV） and inflammatory markers （vascular cell adhesion molecule-1, VCAM-1; monocyte chemoattractant protein-1, MCP-1 ; interleukin-8, IL-8） of human aortat wall were tested by immunofluorescence staining. The levels of MCP-1 and IL-8 mRNA expression were detected by reverse transcription-polymerase chain reaction （RT-PCR）. Results No distinct difference was observed between SSW and the control group on the expression of biological markers as assessed by the light microscope. But the inflammatory markers VCAM-1, MCP-1 and IL-8 on the subendothelial layer and smooth muscle cell layers, which are near the endothelium of arterial wall, were strongly stained in the SSW group compared with the control group. Their fluorescence intensities in the 1：40 SSW group （VCAM-1： 0.35±0.04, MCP-1： 0.34±0.05, IL-8： 0.37±0.05） and the 1：20 SSW group （VCAM-I： 0.40±0.04, MCP-1： 0.52±0.09, IL-8： 0.51±0.07） were significantly stronger than the control group （VCAM-1： 0.12±0.04, MCP-1： 0.06±0.02, IL-8： 0.24±0.03） by semi-quantitative analysis of immunofluorescence （P 〈0.001 vs control）. MCP-1 mRNA expression in the 1：40 SSW （0.15±0.04） and the 1：20 SSW （0.19±0.06） group was significantly higher than in the control group （0.09±0.03）（P 〈0.05, P 〈0.01 vs control）; IL-8 mRNA expression in the 1：40 SSW （0.64±0.12） and 1：20 SSW （0.72±0.

北朝经学范畴下的“北学”,于王朝统一形势下,在“所习章句”层面与南学进行整合,这是通常所说的“北并于南”。通过零散经学记载与论议,可见北朝《春秋》学术的特性,如汉人通经入仕的学术体制,出身草野、转益多师的传承特性,重功利、实用的质朴学风,以及王朝之学的学术取向。唐初《春秋》学宗尚的转变并不影响其所继承的北学因素。借助隋唐《春秋》散论也可发现刘炫、孔颖达以及啖助、赵匡、陆淳这两个《春秋》学高峰间的联系与蜕变。隋唐统一王朝的北学,体现在其精神风貌,《春秋》经学风格的转折也是北学务实、济世等精神元素的体现,且早已超出地域融汇入时代的共同价值。

The impulsive solution for a semi-linear singularly perturbed differential-difference equation is studied. Using the methods of boundary function and fractional steps, we construct the formula asymptotic expansion of the problem. At the same time, Based on sewing techniques, the existence of the smooth impulsive solution and the uniform validity of the asymptotic expansion are proved.

Oceanic evaporation via the East Asian Monsoon （EAM） has been regarded as the major source of precipitation over China, but a recent study estimated that terrestrial evaporation might contribute up to 80% of the precipitation in the country. To explain the contra- diction, this study presents a comprehensive analysis of the contribution of oceanic and terrestrial evaporation to atmospheric moisture and precipitation in China＇s major river basins. The results show that from 1980 to 2010, the mean annual atmospheric moisture （precipitable water） over China was 13.7 mm, 39% of which originates from oceanic evaporation and 61% from terrestrial evaporation. The mean annual precipitation was 737 mm, 43% of which originates from oceanic evaporation and 57% from terrestrial evaporation. Oceanic evaporation makes a greater contribution to atmospheric moisture and precipitation in the East Asian Monsoon Region in South and East China than terrestrial evaporation does. Particularly, for the Pearl River and southeastern rivers, oceanic evaporation contributes approximately 65% of annual precipitation and more than 70% of summer precipitation. Meanwhile, terrestrial evaporation contributes more precipitation in northwest China due to the westerly wind. For the northwestern rivers, terrestrial evaporation from the Eurasian continents contributes more than 70% of precipitation. There is a linear relation between mean annual precipitation and the contribution of oceanic evaporation to precipitation, with a correlation coefficient of 0.92, among the ten major river basins in China.

A new interval arithmetic method is proposed to solve interval functions with correlated intervals through which the overestimation problem existing in interval analysis could be significantly alleviated. The correlation between interval parameters is defined by the multidimensional parallelepiped model which is convenient to describe the correlative and independent interval variables in a unified framework. The original interval variables with correlation are transformed into the standard space without correlation,and then the relationship between the original variables and the standard interval variables is obtained. The expressions of four basic interval arithmetic operations, namely addition, subtraction, multiplication, and division, are given in the standard space. Finally, several numerical examples and a two-step bar are used to demonstrate the effectiveness of the proposed method.
