简介：all-k-nearest-neighbor(AkNN)询问为每个询问对象发现k最近的邻居。这个问题在许多区域自然地产生，例如GIS(地理信息系统)，多媒体检索，和recommender系统。到各种各样的数据类型和灵活距离度量标准在真实应用程序包含了的支持，也就是，我们在公制的空格学习AkNN检索公制的AkNN(MAkNN)搜索。认为询问上的内在的索引设定，目标集合不能存在，它在许多情形是自然的。例如，询问集合和对象集合能是另外的询问的结果，并且这样，内在的索引不能预先被造。到没有任何内在的索引的数据集上的支持MAkNN搜索，我们建议一个有效基于磁盘的算法，作为基于分区的MAkNN算法(PMA)称为，它跟随一个分区搜索框架并且为加速搜索采用一系列修剪的规则。另外，我们扩大我们的技术处理MAkNN询问的有趣的变体，即，公制的self-AkNN(MSAkNN)搜索，在询问集合与对象相同的地方，设定。用真实、合成的数据集的广泛的实验表明我们的修剪的规则的有效性和建议算法的效率，与最先进的MAkNN和MSAkNN算法相比。

简介：基于线虫生活策略，成熟索引(MI)在1990被建议了估计可能的变化陆上并且淡水线虫集合由人为的活动导致了。它随后也被用于海洋的生态系统并且比较地还没很流行，在与大量人为的司机的关系估计生态的质量提供一个好方法。然而，很少数据在它对物理应力的反应上是可得到的，特别在沿海的区域的一个关键因素。在这研究，从在马尔代夫执行的二学习格的海洋的线虫类被用来测试MI和生活策略特点(即，c-p班)为检测物理骚乱的效果。结果证实线虫很好被使适应显示出恢复的一般的高率的物理应力。可伸缩的C-p和MI不似乎为因为几个类，和对各种各样的骚乱类型的可能的微分回答的生活策略上没有实验证据，可能揭示这种骚乱类型适当可以被假设。
