A new technique for calculating fourier integrals based on the poisson summation formula

This paper derives a general method for the calculation of Fourier integrals based on the Poisson summation formula. The approach is an extension of that due to Medhurst (1960) and can be thought of as an extension of the Mobius inversion formula. Useful applications are to the calculation of probability density funtions from their Fourier transforms.     

汉英句法方面的差异对比

汉语与英语在句子结构方面有很多不同之处 ,比如在复合句中关联词的使用方面 ,在句子成分的省略方面 ,在使用主谓语序倒装句的频率方面 ,在句子成分对词性的要求方面等均存在一定差异。初学英语者在表达思想时切不可生套汉语句型。     

An integral representation technique for calculating general multivariate probabilities with an application to multivariate x2

Recently in Dutt (1973, (1975), intgral representations over (0,A) were obtained for upper and lover multivariate normal and the probilities. It was pointed out that these integral representaitons when evaluated by Gauss-Hermite uadrature yield rapid and accurate numerical results.

Here integral representaitons, based on an integral formula due to Gurland (1948), are indicated for arbitrary multivariate probabilities. Application of this general representaion for computing multivariate x2 probabilities is discussed and numerical results using Gaussian quadrature are given for the bivariate and equicorre lated trivariate cases. Applications to the multivariate densities studied by Miller (1965) are also included     

话语、逻辑与反转：德里达的解构——以Khora为分界线

对于逻各斯的话语和逻辑，德里达延续了其一贯的态度，那就是通过指明差异和断裂的存在来反抗其内在的统一和完整性。Khora是反抗力量的一个代表，它以第三类话语出现在逻各斯系统内，既不委从于理性的律法秩序，也不屈服于感性的宗教皈依，而是以“无所表达”而“不被表达”的他者身份打开了通往异质性结构的征途。因此，Khora的独特身份揭示了逻各斯自身的断裂和分化。为了掩盖异质存在所造成的断裂从而达到叙事的完整性，逻各斯施加了一种反转的手段以达到这种效果。德里达认为反转是逻各斯所施加的一种暴力的表现，它试图抹消和抵制理想与现实之间的断裂，取消差异的存在。因此，解构实质上是对这种暴力的消解，通过消解使得文本的内在异质性和丰富性作为一种客观存在被呈现出来。     

Test inversion bootstrap confidence intervals

In this paper we explore the theoretical and practical implications of using bootstrap test inversion to construct confidence intervals. In the presence of nuisance parameters, we show that the coverage error of such intervals is O ( n ^−1/2) which may be reduced to O ( n ⁻¹) if a Studentized statistic is used. We present three simulation studies and compare the performance of test inversion methods with established methods on the problem of estimating a confidence interval for the dose–response parameter in models of the Japanese atomic bomb survivors data.     

论社会科学应用研究成果转化为生产力的特征

社会科学应用研究成果转化作用于社会生产力的特征是多维的、间接的、长远的。社会科学应用研究成果转化作用于社会生产力产生的效果不像自然科学技术那样, 直接作用于物质生产或物质生产过程的有关生产力要素, 通过生产力要素的改变、影响生产力的变化, 而是从体制、制度、政策法规、决策、运筹、管理等更高层面上对生产力要素进行优化、整合,使生产力要素实现合理配置后, 再发挥作用,推动和促进社会生产力发展。     

疏离与倒置——对20世纪中国文论与文学的反思

立足于世纪之交文论“失语症”和重建中国文论话语的学术背景 ,全面回顾了 2 0世纪中国文论与文学所走过的历程 ,指出文论“失语症”是由于文论与文学之间的疏离、隔膜、倒置、错位所导致的。     

Mean-Minimum Exact Confidence Intervals

This article introduces mean-minimum (MM) exact confidence intervals for a binomial probability. These intervals guarantee that both the mean and the minimum frequentist coverage never drop below specified values. For example, an MM 95[93]% interval has mean coverage at least 95% and minimum coverage at least 93%. In the conventional sense, such an interval can be viewed as an exact 93% interval that has mean coverage at least 95% or it can be viewed as an approximate 95% interval that has minimum coverage at least 93%. Graphical and numerical summaries of coverage and expected length suggest that the Blaker-based MM exact interval is an attractive alternative to, even an improvement over, commonly recommended approximate and exact intervals, including the Agresti–Coull approximate interval, the Clopper–Pearson (CP) exact interval, and the more recently recommended CP-, Blaker-, and Sterne-based mean-coverage-adjusted approximate intervals.     

综合多种方法识别济阳拗陷反转构造

陆相断陷湖盆陡坡带常发育多种砂体,由于其地震反射特征的特殊性,干扰了反转构造的识别。结合孤北洼陷五号桩断层带正反转褶皱和高青地区高青—平南断层正反转构造实例,分析了反转构造的地震反射特征,运用钻井资料进行地层细分和对比,声波时差进行剥蚀量的计算,流体包裹体的性质判断构造应力性质。五号桩断层带正反转褶皱地震反射特征呈现上凸下凹的外形,上部地层中间厚、两翼薄,且褶皱顶部遭受剥蚀,同相轴削蚀现象明显,下部地层保留了断陷盆地沉积充填特征;钻井资料亦显示背斜核部遭受剥蚀;声波时差随深度变化的关系曲线在剥蚀段明显错开。高青—平南断层发现了表征张性和压性环境的两类包裹体。多种方法相互约束可提高反转构造识别的准确率。
