Genomic responses to increased temperature and pollinator selection in Brassica rapa L.
New Phytologist, EarlyView.Summary Rapid environmental change reshapes both abiotic stress and biotic interactions, yet it remains unclear how these combined forces structure plants' genomic adaptation. In particular, the joint influence of temperature and pollinator identity, two ecological axes undergoing simultaneous global shifts, has rarely been quantified at genomic ...

鄂尔多斯盆地姬塬地区长6 储层矿物含量与孔隙度的线性关系 [PDF]
, 2019 矿物含量是影响储层物性的重要因素之一。为了较全面地分析不同类型矿物含量对储层孔隙度的影响，以鄂尔多斯盆地姬塬地区长6 砂岩储层为例，探索性地运用多元逐步线性回归法分析了石英含量（x1）、长石含量（x2）、岩屑含量（x3）、绿泥石含量（x4）、伊利石含量（x5）、高岭石含量（x6）、硅质含量（x7）以及铁方解石含量（x8）与孔隙度（y）的关系，建立了矿物含量（xi）与孔隙度（y）之间的回归模型：y = 21.131-0.086 x2-0.113 x3-0.554 x4-0.370 x5-0.199 x6 ...

Issue Attention in Public Opinion Polls: Pollsters as Agenda Responders and Agenda Setters
Policy Studies Journal, EarlyView.ABSTRACT Polling organizations, like other policy actors, must prioritize certain issues. We argue that, for normative and financial reasons, pollsters prioritize issues that are viewed as important by other institutions and the public, leading them to focus survey questions on issues that are on congressional and media agendas, and which are public ...

Study on Influences of Subway Construction on Neighboring Surface and Buildings [PDF]
, 2016 近年来，我国城市化进程加快，城市地铁建设发展迅猛，为缓解城市交通拥堵发挥了重要作用。然而，地铁大多位于城市繁华地区，地面建筑物林立，施工对周边建筑物所产生影响也表现得越来越突出。本文以厦门市轨道交通1号线工程为背景，在对实测变形监测资料详细分析的基础之上，研究了地铁施工引发周边建筑地基及地表变形的预测方法，总结了地铁施工引发周边建筑地基变形的影响因素与规律，提出了适用于厦门地区地铁施工对周边建筑物影响的控制指标及安全评估方法。主要研究内容及成果如下： （1）根据实测数据统计 ...

Veterinary Dermatology, EarlyView.Canine atopic dermatitis (cAD) is a chronic condition requiring life‐long management. Accurate diagnosis can be challenging, with no reliable diagnostic test. This study aimed to generate a simple diagnostic model for cAD. This model is a relevant prototype for an app‐based tool to support general practitioners in the diagnosis of cAD alongside ...

Zhongshan Daxue xuebao. Yixue kexue ban, 1995 用１１项肝功能试验预测１０３例原发性肝癌合并肝硬变病人的手术前肝储备功能。对照术后恢复状况，对这些检查采用多因素判别法（Ｆｉｓｈｅｒ＇ｓ法）分析。推导出两个方程式。用Ｙ１方程式预测病人术后是否出现肝功能损害，Ｙ２方程式预测肝功能损害的程度。用方程式回代，两个方程式的预测准确率分别为８８．０％和８３．１％。为了更准确地预测肝储备功能，我们设计了二步判别法，其预测敏感性、准确性和阴性预测值均高于Ｐｕｇｈ法（Ｐ＜０．０５）。再用此法对另外一组病人（ｎ＝６０）作术前预测，准确率分别为８３．３％和７７．８％。
