Therapeutic Hypothermia: Quantification of the Transition of Core Body Temperature Using the Flexible Mixture Bent‐Cable Model for Longitudinal Data

Hypothermia which is induced by reducing core body temperature is a therapeutic tool used to prevent brain damage resulting from physical trauma. However, all physiological systems begin to slow down due to hypothermia and this can result in increased risk of mortality. Therefore quantification of the transition of core body temperature to early hypothermia is of great clinical interest. Conceptually core body temperature may exhibit an either gradual or abrupt transition. Bent‐cable regression is an appealing statistical tool to model such data due to the model's flexibility and readily interpretable regression coefficients. It handles more flexibly models that traditionally have been handled by low‐order polynomial models (for gradual transition) or piecewise linear changepoint models (for abrupt change). We consider a rat model to quantify the temporal trend of core body temperature primarily to address the question: What is the critical time point associated with a breakdown in the compensatory mechanisms following the start of hypothermia therapy? To this end, we develop a Bayesian modelling framework for bent‐cable regression of longitudinal data to simultaneously account for gradual and abrupt transitions. Our analysis reveals that: (i) about 39% of rats exhibit a gradual transition in core body temperature; (ii) the critical time point is approximately the same regardless of transition type; and (iii) both transition types show a significant increase of core body temperature followed by a significant decrease.     

Media advocates,Latino citizens and niche cable The limits of ‘no limits’ TV

In Shot in America, Chon Noriega calls for the study of media activism’s work ‘within the system’ of state institutions and for analysis of the relationships between media activism, the television industry and government policies. This article uses a cultural policy studies focus to answer this call and map the deregulated terrain upon which media advocacy groups must now operate. Liberal governance demands that media advocates find means other than state-directed appeals to advance their agendas. As such, this essay examines the efforts of several Latino advocacy groups to garner viewer support for a Latino-themed cable television show, Resurrection Boulevard, and to use the series as a vehicle for increased Latino participation in the television industry. This article focuses on the issue of access for Latinos to professional positions that affect television programming, and it presents tools for advocacy efforts within political spheres to achieve more socially equitable access to media technologies. First, the paper traces the regulatory history of the broadcasting and cable television industries to show how the federal government narrowly conceives of ‘the public interest’ as a specifically consumerist one. The article then analyses the structures that led to cable television’s ‘narrowcasting’ format, such as Showtime’s ‘No Limits’ programming, and argues that liberalism has created a context wherein several media advocates normalise the ‘citizen-consumer’ model. Having established this groundwork, the author then conducts a case study of the economic and social forces that shape Resurrection Boulevard, which is written, produced and acted by Latinos. Through this study, the author maintains that advocacy groups’ consumer-based appeals to Latinos as ‘citizen-consumers’ fail to serve as effective instruments for achieving increased minority representation in the television industry.

千米级斜拉桥主梁挠度非线性随机静力分析

采用响应面法对千米级斜拉桥主梁最大挠度进行静力可靠度分析,考察主梁最大挠度随结构材料、几何尺寸及外荷载等不确定因素的变异而发生变化的规律。算例研究表明,主梁挠度可靠指标对各随机变量平均值和标准差的敏感程度不同。同其它随机变量相比,斜拉索弹性模量变异对千米级斜拉桥主梁挠度影响最为显著。主梁截面面积变异对千米级斜拉桥主梁挠度具有显著的影响,但与对千米以下斜拉桥主梁挠度的影响规律不同。     

如何共享cable modem宽带上网

在目前电信大力推广的Internet宽带接入方式中,大多采用以太网接入或ADSL接入方式.而在尚未开通上述业务的地区,只要能够接收到电信的有线电视信号,就可采用线缆调制解调器(即cable modem)接入方式,我院目前采用的就是这种宽带上网的方法.本文从实用技术角度,对相关的网络安装配置操作做了较为详细的介绍.

面向损伤识别的独塔斜拉桥模型的设计与分析

模型试验方法是桥梁结构损伤识别研究的一种重要手段。以某虚拟的独塔斜拉桥为原型,面向损识别设计制作了独塔斜拉桥试验模型。试验模型各主要构件（主梁、主塔、斜拉索）均独立加工制作,其中主梁选用铝合金材料,截面采用箱形,划分为不同长度的阶段,各节段均采用螺栓连接。通过改变节段板厚的方法实现主梁不同损伤程度的模拟,不同位置的损伤通过更换不同位置的板厚实现,从而方便的实现了模拟模型斜拉桥主梁的各种损伤状态。采用特殊的设计实现了斜拉桥结构索力的实时测试。对模型进行了静态试验,并与有限元模型计算的结果进行了对比分析。试验研究与数值分析为今后的损伤识别研究奠定了基础。     

国内马克思哲学超越维度理论研究现状述评

以实验室独塔斜拉桥为研究对象,提出了确定斜拉桥合理施工索力的正装倒拆计算法,该方法按照施工顺序,在正装优化的基础上,对各节段进行倒拆计算,得到各斜拉索的基础索力,然后再通过正装迭代计算,求得各个调索阶段斜拉索的初始张拉索力和主梁的预抬量,从而避免了传统的倒拆法中难以考虑结构本身的非线性问题与正装法无法保证计算过程中一些索力设置大小的合理性等问题。本方法已经在独塔斜拉桥模型实验中成功应用。通过实验验证了该方法的有效性和可靠性,具有一定的理论价值和重要的应用价值。
