    • The present invention faces the issue of data replication in different database nodes of a geographically distributed database wherein clients cannot always perform any database-related operation in the closest database node. Thus, the present invention provides for an enhanced distributed database system with a plurality of nodes, each node arranged for storing a replica of at least one partition of data, and a method of handling said distributed database system comprising the steps of: partitioning data into a number of partitions; replicating each partition into a number of replicas; for each partition, distributing the number of replicas amongst database nodes; activating more than one node; monitoring at each active node events of: latest updating of each replica, replica status, status of local resources in charge of each replica, and connectivity status of each replica; upon activation or deactivation of a node, determining which node is considered current master node for each partition in charge of current master replica; for any request received in a node to read/write data, determining the current master node in charge of the current master replica, and routing said request to said current master node.
    • 本发明面临地理分布式数据库的不同数据库节点中数据复制的问题,其中客户端不能总是在最近的数据库节点中执行任何数据库相关的操作。 因此,本发明提供了一种具有多个节点的增强型分布式数据库系统,每个节点被布置用于存储至少一个数据分区的副本,以及一种处理所述分布式数据库系统的方法,包括以下步骤:将数据分成 一些分区; 将每个分区复制到多个副本中; 为每个分区分配数据库节点之间的副本数; 激活多个节点; 每个活动节点上的监视事件:每个副本的最新更新,副本状态,每个副本负责的本地资源的状态以及每个副本的连接状态; 在节点的激活或去激活时,确定哪个节点被认为是负责当前主副本的每个分区的当前主节点; 对于在节点中接收到的用于读/写数据的请求,确定当前主节点负责当前主副本,并将所述请求路由到所述当前主节点。

    • A transmitting node in a telecommunications network, wherein data are distributed into one or more data storage groups (DSG), and wherein data related to a DSG is replicated into a plurality of data storage elements (DS) distributed along one or more nodes of the network. The transmitting node includes a network interface through which a bi-directional connection is established with a plurality of other nodes in a transport layer of the network, and from which messages are sent to the plurality of other nodes comprising an operational state matrix (OSM), which includes information held by the transmitting node about the operational state of the replicas of the DSs of each DSG. The transmitting node includes a memory for storing data. The transmitting node includes a processing unit which forms a list of the plurality of other nodes as having an answer pending of the node in the memory. The network interface receives an OSM from at least some of other nodes which are interpreted by the processing unit as answer messages from the list of the plurality of other nodes to the messages sent by the network interface, and which indicates that an OSM information exchange with the plurality of the other nodes is complete. The processing unit decides a node hosting the master DS replica of each DSG based on the OSM information exchange. The processing unit detects changes in a view of the world (VOW) which includes an accumulated set of OSMs with respect to each DSG hosted by the transmitting node. The network interface sends messages comprising changes in the VOW to the other nodes.

    • A method for preparing aromatic polyamines comprising (1) preparing a non-aqueous aminal solution; (2) contacting the non-aqueous aminal solution and an acidic siliceous catalyst to form a benzylamine intermediate; (3) contacting the benzylamine intermediate and an ion exchange resin catalyst based on a styrene-divinylbenzene copolymer to form an aromatic polyamine reaction mixture containing a polyaminopolyphenyl methane product; and (4) recovering the polyaminopolyphenyl methane product from the aromatic polyamine reaction mixture. The method, which may be practiced continuously, offers high 4,4'-methylene dianiline yield, reduced impurities, extended catalyst life, and, therefore, improved economics, when compared with many conventional methods to prepare polyaminopolyphenyl methanes.

    • The present invention describes methods and apparatus to prepare a heart valve for replacement and improve a deficient heart valve. An exemplary embodiment of the method of preparing a heart valve for replacement involves delivering an anchoring conduit to a heart valve. The anchoring conduit is expanded in the heart valve. Furthermore, the expansion of the anchoring conduit defines an open cavity. An exemplary embodiment of the method of improving a deficient heart valve involves delivering an anchoring conduit to a heart valve. The anchoring conduit has a harbor, which is enabled to releasably connect a heart valve prosthesis. Then, a temporary valve is delivered in a condensed state to a target site in an artery proximate the heart valve. Subsequently, the anchoring conduit is deployed in the heart valve, disabling the heart valve. The temporary valve operates to temporarily replace the function of the heart valve when the anchoring conduit is expanded.
