Design and Implementation of Public Security Intelligence Search-Platform Based on Big Data Technology [PDF]
, 2015 公安信息化的高速发展积累了丰富的业务数据，种类不断增加、结构不断异化、总量不断增长，截至2014年底，全国公安机关掌握的数据资源已达100多类上千亿条,信息数据已成为继警力资源、装备资源之后的新一类核心资源。搜索是公安信息获取和进行研判的基础手段。传统的全文搜索系统存在大量结果数据“堆积”、再次筛查工作量大、目标结果无法精准定位，使用效率低下等问题。利用分布式计算架构，融合了SolrCloud、Zookeeper、高速缓存等技术手段，以人、车、案为对象重组数据，采用智能分析、对象全景档案等手段 ...

Distribution, scale, and drivers of mass mortality events in Europe's freshwater bivalves
Conservation Biology, EarlyView.Abstract Mass mortality events (MMEs) are decimating populations and compromising key ecosystem functions around the globe. One taxon particularly vulnerable to MMEs is freshwater bivalve mollusks. This group has important ecosystem engineering capacities and includes highly threatened and highly invasive taxa.

How much biotic nativeness matters across human demographic groups
Conservation Biology, EarlyView.Abstract Many central concepts of conservation biology—such as nativeness—are structured by ecological and social factors. However, the social consequences of using these concepts to make conservation decisions remain inadequately understood. Some researchers argue that nativeness, rather than acting as an objective proxy for important ecological ...

Research of KNN Graph Algorithm Parallelization based on Spark and Its Application [PDF]
, 2016 近些年来，随着计算机科学技术的迅速发展，越来越多的海量数据信息在许多行业中随之产生，海量数据对数据处理的效率提出了极大的挑战。同时在此背景下分布式计算也得到了大力发展，Hadoop使得用户可以进行超大数据集的分析，但是其基于磁盘的MapReduce的计算严重影响了计算性能，而Spark引入RDD(ResilientDistributedDatasets)基于内存计算迎合了广大用户的需求，极大提高了分布式并行计算的效率。虽然在众多大数据工具中，Spark得到了很大的关注，但是Spark还不是十分完善 ...

Informing spatial conservation prioritization with species’ traits
Conservation Biology, EarlyView.Abstract New Guinea, the most botanically diverse island on the planet, is the location for one of the boldest conservation initiatives. The Manokwari Declaration aims to achieve 70% conservation designation for the Bird's Head Peninsula. This is 40% higher than the 2022 Global Biodiversity Framework target.

Differences in characteristics between naturalized threatened plants and other threatened plants
Conservation Biology, EarlyView.Abstract Many non‐native plant species introduced by humans have become naturalized. At the same time many species are threatened in their native range. However, the number of plant species threatened in their native range that are naturalized elsewhere remains unknown.

Zhejiang Daxue xuebao. Lixue ban, 2015 基于传统磁盘数据库的管理系统已能较好地管理土地利用矢量数据，但较大的内外存数据交换开销对系统实时性有一定影响.没有I/O开销的内存数据库将是解决该现状的良好方法.基于内存数据库Redis设计土地利用矢量数据库存储组织，提出点、线、面不同的空间要素空间特征数据的存储结构.采用缓存敏感优化并基于磁盘数据库中的空间索引R+树，提出了一种适合Redis的空间索引.对比实验发现，在数据查询和统计分析速度等方面较基于Oracle 10 g的管理系统有较大提升.

Comprehensive framework for assessing and optimizing existing research networks
Conservation Biology, EarlyView.Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...
