Instance matching, which aims at discovering the correspondences of instances between knowledge bases, is a fundamental issue for the ontological data sharing and integration in Semantic Web. Although considerable instance matching approaches have already been proposed, how to ensure both high accuracy and efficiency is still a big challenge when dealing with large-scale knowledge bases. This paper proposes an iterative framework, RiMOM-IM （RiMOM-Instance Matching）. The key idea behind this framework is to fully utilize the distinctive and available matching information to improve the efficiency and control the error propagation. We participated in the 2013 and 2014 competition of Ontology Alignment Evaluation Initiative （OAEI）, and our system was ranked the first. Furthermore, the experiments on previous OAEI datasets also show that our system performs the best.

Chylothorax is an uncommon disease where fatty fluid accumulates within the chest cavity. Conservative manage- ment, including repeated thoracentesis or pleurodesis, seems to be suitable to most cases. Herein, we present a case of efficacious pleurodesis by intrapleural injection of Sapylin, a streptococcus preparation, for the treatment of chylothorax. A 52-year-old non-smoking female farmer was diagnosed as idiopathic chylothorax after we ruled out possible causes including chest trauma, lymphoma, lung cancer, filariasis, tuberculosis, and etc. Two-time intra-thoracic injection of 3 Klinische Einheit (KE) Sapylin achieved rapid and effective control of chylothorax with no severe side effects. Sapylin may facilitate pleurodesis by producing a strong inflammatory response.

对布设在南北构造带北段的中国地震科学探测台阵项目二期674个宽频带流动台站和鄂尔多斯台阵21个宽频带流动台站记录的远震XKS(SKS、SKKS和PKS)波形资料作偏振分析,采用最小切向能量的网格搜索法和"叠加"分析方法求得每一个台站的XKS波的快波偏振方向和快、慢波的时间延迟,并结合该区域出版的122个固定台站的分裂结果,获得了南北构造带北段上地幔各向异性图像.快波方向分布显示青藏高原东北缘、阿拉善块体和鄂尔多斯块体西缘的快波方向主要表现为NW—SE方向,秦岭造山带的快波方向为近E—W方向,鄂尔多斯块体内部的快波方向在北部为近N—S方向,南部表现为近E—W方向.时间延迟分布来看,鄂尔多斯块体的时间延迟不仅明显小于其周缘地区,而且小于其他构造单元,特别是在高原东北缘、阿拉善块体和鄂尔多斯块体的交汇地区的时间延迟很大,反映了构造稳定单元的时间延迟小于构造活跃单元.通过比较快波方向的横波分裂测量值与地表变形场模拟的预测值,并结合研究区地质构造和岩石圈结构特征分析表明,在青藏高原东北缘、阿拉善块体和鄂尔多斯块体西缘各向异性主要由岩石圈变形引起,地表变形与地幔变形一致,地壳耦合于地幔,是一种垂直连贯变形模式;秦岭造山带的各向异性不仅来自于岩石圈,而且其岩石圈板块驱动的软流圈地幔流作用不可忽视;鄂尔多斯块体内部深浅变形不一致,具有弱的各向异性、厚的岩石圈和构造稳定的特征,我们认为其各向异性可能保留了古老克拉通的"化石"各向异性.
