云存储服务中,批量审计是高效验证云端数据完整性的关键技术.批量审计容易遭受"失效文件"攻击,并且查询失效文件代价高、速度慢,严重影响着批量审计方案的可用性和效率.针对该问题,提出一种支持失效文件快速查询的批量审计方法,该方法通过建立批量审计过程的关联性,改变了二分查询树中右孩子节点的计算方式,减少了整个查找过程的批量审计次数;并在批量审计过程中执行幂指测试,通过一次审计就可完成含有单个失效文件的子树查找过程,有效缩短了子树的查找长度;采用混合型查询方法,根据历史查询信息设置幂指测试的深度,降低了"失效文件聚集处"的查询开销.安全分析和性能表明,该方法能够快速完成失效文件定位,有效抵抗"失效文件"攻击,保证了批量审计方案的可用性和效率.在少量文件失效的情景下,相较于简单二分查找方法,文中方法耗费的批量审计次数减少了30%.

为提高包埋厌氧氨氧化菌材料的机械稳定性,通过实验对包埋原材料组合进行筛选并在制备过程中添加海水对材料性能进行优化.结果显示:最优材料配比为聚乙烯醇(PVA 125 g·L^(-1))-海藻酸钠(SA 20 g·L^(-1))-活性炭(40 g·L^(-1)),固化时间为18 h.添加海水优化后,由于霍夫迈斯特效应,胶珠内部孔径较大且分布不均,机械稳定性和生物容纳量明显高于淡水组,根据拉曼光谱解析表明添加海水后胶珠中—OH可更大程度与交联剂发生交联反应.利用活化后的包埋菌处理含海水污水,经过21 d的运行NH_4^+-N去除率达到90%左右,化学计量比ΔNH_4^+-N∶ΔNO_2^--N∶ΔNO_3^--N稳定在1∶(1.04±0.1)∶(0.17±0.02),自第21 d开始静止运行至第46 d后负荷提升1倍,氨氮去除率和化学计量比无明显波动,总氮去除率稳定在85%左右,总氮去除负荷为0.2 kg·(m^3·d)^(-1).

Dear Editor, Phenotypic drug discovery, which observes compound effects on physiology,has given way to targeting specific molecules, but has revived by using modern methods to find drugs based on therapeutic outcomes in disease models(Vincent et al., 2022). Osteoarthritis(OA) is a prevalent chronic joint disorder, primarily affecting knee joints, with osteoclast activation due to low-grade inflammation resulting in increased bone resorption and structural changes in the joint(Katz et al.,2021).

大数据时代为实现高速与海量数据的存储,对计算机主存的性能提出了更高要求,相变存储器PCM应运而生。PCM凭借其非易失、字节可寻址、存储密度高、能耗低等优点,一度被认为有望代替DRAM成为新的主存存储介质。但是,现阶段的PCM存在写延迟高、寿命有限等问题,还不能取代DRAM作为主存。因此,利用DRAM和PCM优劣互补来构建存储速度更快、存储容量更大、能量效率更高的混合主存系统,以共同承担主存中的大数据存储、管理任务,成为现阶段的最佳主存架构机制。
