Accuracy of approximate progressively censored reliability sampling plans for exponential models

Reliability sampling plans provide an efficient method to determine the acceptability of a product based upon the lifelengths of some test units. Usually, they depend on the producer and consumer’s quality requirements and do not admit closed form solutions. Acceptance sampling plans for one- and two-parameter exponential lifetime models, derived by approximating the operating characteristic curve, are presented in this paper. The accuracy of these approximate plans, which are explicitly expressible and valid for failure and progressive censoring, is assessed. The approximation proposed in the one-parameter case is found to be practically exact. Explicit lower and upper bounds on the smallest sample size are given in the two-parameter case. Some additional advantages are also pointed out.

1966年至1978年洞庭湖地区血吸虫病流行特点

洞庭湖地区血吸虫病流行因素很复杂，复杂性在于湖区居民生产、生活与湖区环境产生的千丝万缕的联系，如果没有政府的主导性作用，切断血吸虫病的传播途径，控制疫情的蔓延是不可想象的难题。血吸虫痛的流行程度与政府主导地位的发挥程度在一定意义上说是成正比的关系。这在“文革”时期表现得很突出。洞庭湖地区血吸虫病的流行在文革时期以1970年为分水岭呈现出泾渭分明的特征，已超出了流行病学上的意义，更体现它的社会学价值。     

论高校阳光辅导员的培育

践行科学发展观，走特色发展之路

科学发展观的第一要义是发展，在目前激烈的竞争中走特色发展之路，对于新建地方应用型本科院校至关重要。办学特色是指：“人无我有、人有我优、人优我特”，具有“独特性、稳定性、发展性和优质性”的特点。在深入剖析徐州工程学院发展阶段特征及在同类院校中所处的位置的基础上，提出围绕“地方性、应用型、工程类、多学科”特点，坚持“有所为，有所不为”的学科发展战略，依托地方特点，打造区域特色品牌，在服务地方经济社会中走出一条特色办学之路。     

Mathematical forms of the distribution of the product of two normal variables

This paper finds the mathematical forms of the distribution of the product where x and x follow a bivariate normal distribution In this paper the distribution when PT0 is expressed as an integral, a new, fundamental result. From this general form, six different cases can be distinguished depending on what is known about the parameters and p. The special cases are Aroian $year:1959 and (6) Additionally, we prove that if and as the distribution of the product approaches the Type III distribution. When p=0# Aroian $year:1959 and Aroian and Meeker $year:1977, give tables for various values of 6., 6 . The results in this paper will be used to provide brief tables for p^O in a separate paper

新时期社会转型的中国经验——新时期社会转型与和谐社会构建问题战略层面上的比较价值

中国新时期社会转型与和谐社会构建问题,是中国经济社会发展进程中提出和探索的具有全局性、战略性的双重命题,是对我国现代社会发展规律的基本认识,也是对中国改革与发展进程的一种新的理解.这双重命题必须同时上升为执政党和政府的时代性理念,必须置于中国特色社会主义这一"核心主题"的主流分析框架之下;必须从同等程度意义上,上升为执政党和政府的战略性决策层面;改革开放30年的今天,迫切需要分析中国特色社会主义的现代社会转型与和谐社会构建的内在联系;必须从真理性与价值性之统一的角度解析中国特色的现代社会转型与和谐社会构建问题双重命题的同等程度范畴的现实价值.     

Analysis of microtubule dynamics using growth curve models

Microtubules are part of the structural network within a cell's cytoplasm, providing structural support as well as taking part in many of the cellular processes. A large body of data provide evidence that dynamics of microtubules in a cell is reponsible for the performance of many critical cellular functions such as cell division. In this article, we study the effect of four different isoforms of a protein tau on microtubule dynamics using growth curve models. The results show that a linear growth curve model is sufficient to explain the data. Moreover, we find that a mutated version of a 3-repeat tau protein has a similar effect as a 4-repeat tau protein on microtubule dynamics. The latter findings conform with the biological understanding of the effect of the protein tau on microtubule dynamics.
