In the subset of patients not known to take aspirin, 24% had reduced platelet activity. Sixteen (24%) patients received a platelet transfusion 21.2+/-11.4 hours after symptom onset with an increase in platelet activity (448 [414-479] to 586 [530-639] ARU, P=0.001), but without impact on outcomes.

在不知道服用阿司匹林的亚组患者中，24%的患者血小板活性降低。16名（24%）患者在出现症状后21.2+/-11.4小时接受了血小板输注，他们的血小板活性是增加的（448 [414-479] - 586 [530-639] ARU，P=0.001），但是这点对预后无影响。

In addition to highlighting a new class of organizational problems, we argue that in a world of boundedly rational actors, incomplete guides to action in the sense of providing only a subset of underlying goals prove more effective at directing and coordinating behavior than more complete representations of underlying objectives.

除了强调一类新的组织问题，我们认为在有限理性者的世界中，提供子集目标的不完全行动指南在指导和协调行动方面比完整陈述的基本目标要有效得多。

This dissertation investigates the construction of pseudo-random sequences (pseudo-random numbers) from elliptic curves and mainly analyzes their cryptographic properties by using exponential sums over rational points along elliptic curves. The main results are as follows:(1) The uniform distribution of the elliptic curve linear congruential generator is discussed and the lower bound of its nonlinear complexity is given.(2) Two large families of binary sequences are constructed from elliptic curves. The well distribution measure and the correlation measure of order k of the resulting sequences are studied. The results indicate that they are "good" binary sequences which give a positive answer to a conjecture proposed by Goubin et al.(3) A kind of binary sequences from an elliptic curve and its twisted curves over a prime field F_p. The length of the sequences is 4p. The "1" and "0" occur almost the same times. The linear complexity is at least one-fourth the period.(4) The exponential sums over rational points along elliptic curves over ring Z_ are estimated and are used to estimate the well distribution measure and the correlation measure of order k of a family of binary sequences from elliptic curves over ring Z_.(5) The correlation of the elliptic curve power number generator is given. It is proved that the sequences produced by the elliptic curve quadratic generator are asymptotically uniformly distributed.(6) The uniform distribution of the elliptic curve subset sum generator is considered.(7) We apply the linear feedback shift register over elliptic curves to produce sequences with long periods. The distribution and the linear complexity of the resulting sequences are also considered.

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.
