简介：中国microblogs的意见目标抽取在意见采矿起一个重要作用。最近在这个区域有重要进步，特别方法基于有条件的随机的地(CRF)。然而，这个方法仅仅考虑词典相关的特征并且不挖掘暗示了语法、语义的知识。我们建议与一些句法、语义的特征一起合并领域词典的一条新奇途径。途径通过基于词嵌入通过Partof讲话，相关性结构，短语结构，语义角色和语义类似探索语法、语义的信息的一个新奇方法获得领域词典。然后我们把领域词典与意见目标为意见目标抽取与一些特征一起从CRF提取了相结合。COAE2014数据集上的试验性的结果在意见目标抽取的任务与另外的著名方法相比显示出途径的outperformance。

简介：AIMTo估计角膜的矩阵作为脚手架过去常重建的非细胞组成的驼鸟张力亢进的盐溶液与一个消化方法相结合的损坏cornea.METHODSA习惯于decellularize驼鸟角膜。非细胞组成的角膜的矩阵的微观结构被传播电子显微镜学(TEM)和hematoxylin和曙红观察(H&；E)染色。机械性质被一个电流计和一台紧张机器检测。非细胞组成的角膜的矩阵也被移植进一个兔子角膜和cytokeratin3被用来检查有免疫力的phenotype.RESULTSThe微观结构和驼鸟角膜的机械性质很好在decellularization过程以后被保存。在vitro，甲基thiazolyltetrazolium结果表明非细胞组成的驼鸟角膜(AOC)的摘录没在增长上有禁止的效果角膜上皮或endothelial房间或在keratocytes上。兔子当角膜的混浊和接枝溶解发生在非细胞组成的猪的角膜(APC)时，薄片状的keratoplasty证明移植AOC进主人角膜透明、完全合并移植。重建的角膜的显型类似于有3首先在表面的上皮的房间layer.CONCLUSIONWe使用了的cytokeratin的高表情的一个正常兔子角膜重建的脚手架损坏了角膜的AOC。与猪的角膜相比，驼鸟角膜的解剖结构人的角膜接近那些。根据原则，那结构决定功能，薄片状的keratoplasty也证实了的异种皮移植AOC移植与APC接枝的相比产生了优异结果。
