Design and Implementation of Cloud Storage System Based on HDFS [PDF]
, 2013 随着数据爆炸的时代到来，海量数据存储的问题也随之而来。HDFS（HadoopDistributedFileSystem）作为主流的开源云计算系统Hadoop的基础构件之一，由于其低成本、高度容错、支持大数据集等特点成为解决数据密集型应用的海量数据存储问题的首选方案之一。在HDFS越来越被广大企业重视和采用的时候，HDFS存在的一些问题也逐渐显现。首先，因为HDFS采用Master/Slaves主从架构，一旦Master节点发生故障，整个集群都无法提供服务，因此HDFS存在单点故障。其次 ...

Ciclopirox Olamine Inhibits the NLRP3 Inflammasome to Alleviate Inflammatory Diseases
Advanced Science, EarlyView.There is no drug targeting the NLRP3 inflammasome that has been approved for use in clinical settings. Ciclopirox olamine (CPX), an antifungal agent approved by the US Food and Drug Administration (FDA), is identified as a specific and potent NLRP3 inflammasome inhibitor. CPX targets the NACHT domain of NLRP3 at Y381 to impair NLRP3 oligomerization and
