    • An archive cluster application runs in a distributed manner across a redundant array of independent nodes. Each node preferably runs a complete archive cluster application instance. A given nodes provides a data repository, which stores up to a large amount (e.g., a terabyte) of data, while also acting as a portal that enables access to archive files. Each symmetric node has a set of software processes, e.g., a request manager, a storage manager, a metadata manager, and a policy manager. The request manager manages requests to the node for data (i.e., file data), the storage manager manages data read/write functions from a disk associated with the node, and the metadata manager facilitates metadata transactions and recovery across the distributed database. The policy manager implements one or more policies, which are operations that determine the behavior of an “archive object” within the cluster. The archive cluster application provides object-based storage. Preferably, the application permanently associates metadata and policies with the raw archived data, which together comprise an archive object. Object policies govern the object's behavior in the archive. As a result, the archive manages itself independently of client applications, acting automatically to ensure that all object policies are valid.
    • 归档集群应用程序通过独立节点的冗余阵列以分布式方式运行。 每个节点最好运行一个完整的归档集群应用实例。 给定的节点提供了一个数据存储库,它可以存储大量数据(例如,一千兆字节)的数据,同时还充当允许访问存档文件的门户。 每个对称节点具有一组软件过程,例如请求管理器,存储管理器,元数据管理器和策略管理器。 请求管理器管理对节点的数据(即文件数据)的请求,存储管理器从与该节点相关联的盘管理数据读/写功能,并且元数据管理器便于跨分布式数据库的元数据事务和恢复。 策略管理器实现一个或多个策略,这些策略是确定集群中“归档对象”的行为的操作。 归档集群应用程序提供基于对象的存储。 优选地,应用程序将元数据和策略永久地关联到原始归档数据,其一起构成归档对象。 对象策略管理对象在归档中的行为。 因此,归档管理自身独立于客户端应用程序,自动执行以确保所有对象策略都有效。

    • A file protection scheme for fixed content in a distributed data archive uses computations that leverage permutation operators of a cyclic code. In an illustrative embodiment, an N+K coding technique is described for use to protect data that is being distributed in a redundant array of independent nodes (RAIN). The data itself may be of any type, and it may also include system metadata. According to the invention, the data to be distributed is encoded by a dispersal operation that uses a group of permutation ring operators. In a preferred embodiment, the dispersal operation is carried out using a matrix of the form [IN—C] where IN is an n×n identity sub-matrix and C is a k×n sub-matrix of code blocks. The identity sub-matrix is used to preserve the data blocks intact. The sub-matrix C preferably comprises a set of permutation ring operators that are used to generate the code blocks. The operators are preferably superpositions that are selected from a group ring of a permutation group with base ring Z2.

    • An orthodontic bracket for coupling an archwire with a tooth includes a bracket body configured to be mounted to the tooth and a clip. A clip slot extends through the bracket body transversely to the archwire slot. Upon deflection of the clip, it contacts the bracket body at locations that were not in contact before the deflection. The clip may also have various forms and include various structures that cooperate with the body when the clip is deflected to restrict or stop the deflection. The orthodontic bracket may include a securing mechanism that is configured to secure the resilient ligating clip in the closed position. A method of manufacturing a shaped unsintered body for use in manufacturing an orthodontic bracket is provided. A portion of the sinterable particles may be removed using a stream of energy to yield a plurality of posts which are then deformed.

    • A versioned file system comprises a set of structured data representations. At a first time, an interface creates and exports to a data store a first structured data representation corresponding to a first version of a local file system. The first structured data representation is an XML tree having a root element, one or more directory elements associated with the root element, and one or more file elements associated with a given directory element. Upon a change within the file system (e.g., file creation, file deletion, file modification, directory creation, directory deletion and directory modification), the interface creates and exports a second structured data representation corresponding to a second version of the file system. The second structured data representation differs from the first structured data representation up to and including the root element of the second structured data representation. The data store may comprise a cloud storage service provider.
