Heart failure(HF)is a leading cause of morbidity and mortality in the United States.[1]A chronically,disabling and debilitating condition,HF often results in hospital admission and subsequent readmission.[2]After hos-pitalization,nearly 25%of older adults with HF are discharged to skilled nursing facilities(SNFs)for re-habilitation due to difficulties with functioning in-dependently.[3]Critically,patients with HF dis-charged to SNFs also show significantly higher rates of mortality.[2]Identifying factors that predict mortality among this important patient population,especially factors that could be addressed in the hospital setting,is an important step toward im-proving survivability among these patients.

Nogal住宅是一座由古老乡村果园改造成的现代独栋住宅,它外观如同一块沉默的巨石,但内部却容纳着生命。设计的灵感是在一棵巨大的核桃树的树荫下和周围环境中形成的,这棵核桃树是项目的核心和灵魂。核桃树源自波斯,根深叶茂,树影浓密而修长,木质坚固,姿态雄伟,是大自然的王者之一。为了寻求与大自然的亲密关系,也为了提升这棵百年核桃树的价值,设计师建造了这座具有石头特色的房屋。它让人联想到风景中的岩石,而这些岩石就投射在这个项目的周围。

岩溶研究中,通常会使用高分辨率卫星图像和地理空间数据识别、描绘岩溶发育及相关地质灾害发生的地貌特征。本文旨在利用ArcGIS10.0确定干涉合成孔径雷达数字高程模型(IFSAR-DEM)识别、量化和描述岩溶洼地。这种半自动岩溶洼地/天坑探测方法采用水流模拟法,并结合(1)流域划分;(2)下沉填充法提取洼地特征;(3)下沉深度测量及分类;(4)使用2013年至2014年谷歌高光谱卫星图像和数字地形模型对探测到的岩溶洼地进行验证。该方法已在薄荷省旁劳市进行的评估中进行了预测试。使用国家测绘资源信息局(菲律宾)1991年的1∶50000比例尺地形图进行的初步封闭洼地分析,发现旁劳岛有15个天坑。利用5米高分辨率IFSAR-DEM,共探测到820个天坑,其中424个根据详细的地面实况进行了描绘,以验证了岩溶洼地的存在。地表实况包含天坑大小、形状和深度等基本形态测量分析以消除误报数据。阈值设定为沉降深度大于1米,孔径大于10米,从而最大程度精确区分实际的天坑。这种基于GIS的工具有助于生成高分辨率岩溶塌陷易发区图,继而指导当地规划者、工程师及决策者进行开发规划和土地利用。
