Results The average age of morbidity was 44 years old and the mean disease course of hamartoma was 13 months. 21 cases without symptoms were determinated by chance and 18 cases with some extent of cough,expectoration, fever, chest distress, and short of breath. The hamartomas of 21 cases were in right lung, 18 in the left.

After the analysis it was concluded that the mean velocity fluctuations of the strata under Jidike Group in this working area could be divided into three zones: the minor velocity fluctuation zone in southern Dalaoba tectonic belt, the steep velocity fluctuation zone of the foreslope in middle YK structure and the zone from the bowtype thrusting tectonic belt in northern Qiulige to the minor velocity fluctuation zone in YK tectonic zone. On the basis of a good command of the regular patterns of the velocities in vertical and horizontal dimensions in the investigating area, the stack velocity was interpreted in a interactive mode by using the Depthteam Express modelling package of the Landmark system, converting the stack velocity into mean velocity by means of Dix formula. Based on the well drilling layering data, the velocity correction was executied to get the final corrected velocity model by using the Kriging Correction. By using this velocity model, we did the time to depth conversion and obtained the final depth structural map. After mapping by using the variable velocities, we came in for the display of the tectonic map of the seismic data.
经研究认为本区的吉迪克组以下层位平均速度变化可分成三个变化区域:南部大涝坝构造带速度变化平缓区;中部亚肯构造前缘斜坡区速度变化强烈区;北部秋里塔格弧形逆冲构造带前缘至亚肯构造带速度变化平缓区,在撑握工区速度纵、横向变化规律基础上,应用Landmark解释系统Depthteam Express速度建模软件包对迭加速度进行交互解释,利用DIX公式把迭加速度转换成平均速度,根据区内钻井分层数据采用克里金校正方法进行速度校正,得到最终校正后的速度模型,用此速度模型进行时深转换,得到最终的深度构造图,此次变速成图后,得到地震资料构造图显示。

Firstly, we set a barrier to the underlying asset price under the assumption of common Asian options, the average period begins at the first time when the underlying price hits the barrier. We give a closed-form formula for the Asian call options price with fixed strike price in the case of continuous geometric average and in the case of discrete geometric average.

The main results are as follows:We review the existing Monte Carlo control variates estimators of the price of Asian options and propose a new one. According to pratical needs, we define efficiency as the inverse of the product of the variance of an estimator and its computational time and make it a standard for comparisons to draw the following conclusions: Firstly, the more control variates correlate with arithmetic average Asian options, the larger is the efficiency of an estimator with these control variates, but among which the geometric average option plays the most important role; Secondly, an estimator with more control variates is better than one with less ones only when the time to maturity is long and the volatility is high.
在综合已有研究工作的基础上,本论文的主要创新成果如下:(1)我们回顾了已有的亚洲期权价格的蒙特卡罗控制变量估计,并提出了一个新的控制变量估计,且从客观实际出发,将估计值的方差和计算时间的乘积的倒数定义为效率并以它为标准比较各估计,得到以下结论:与算术平均亚洲期权相关程度越大的控制变量构成的估计的效率越大,而其中起主要作用的控制变量为几何平均亚洲期权的价格;只有在到期时间较长且标的资产的波动率较大时,元素多的多元控制变量估计比元素少的效率大。

The JHU researchers prospectively examined changes in fibrosis stage between paired liver biopsies in 67 coinfected patients. Of the 67 subjects, six were excluded due to cirrhosis on the first biopsy. The median age of group was 44 years, and 75% of the subjects were men. A total of 86% had CD4+ cell counts of less than 200 cells/mm3, and the same number of subjects were receiving antiretroviral therapy. Twenty-seven percent of the patients abused alcohol. The median time between biopsies was 2.84 years (interquartile range, 2.05 - 3.41 years).
