Abstract: One or more techniques and/or systems are provided for detecting stale data and/or changed data. For example, a bitmap file may be maintained and mapped to an inofile describing various states of files of a file system. The bitmap file may be populated with bitmap records indicating whether files were accessed, modified, or have other states. The bitmap file may efficiently convey information used to determine whether files have not been accessed recently (e.g., stale data) or were recently modified (e.g., changed data) compared to the inofile because the bitmap file may comprise a fraction of the size of the inofile (e.g., a byte of information may be used to represent various states of one or more files). In this way, instead of evaluating a relatively larger inofile, the bitmap file may be evaluated to efficiently identify stale data for deletion or destaging and/or changed data for backup.

Abstract: The invention relates to an intervertebral disk prosthesis (10), comprising a caudal plate (20), a cranial plate (30), and an elastic core (40) formed between the caudal plate (20) and the cranial plate (30), wherein the caudal plate (20) has a cavity (25) on the side (21) facing the cranial plate (30), wherein the core (40) is integrally connected to the cavity (25) in the caudal plate (20).

Abstract: A polyaxial pedicle screw has a screw shaft and a screw head with a substantially spherical base shape. The polyaxial pedicle screw is mounted in a receiving sleeve or area. An insertion sleeve can be pressed against the screw head to determine a relative pivot position between the receiving sleeve or area and the screw shaft. Two pivot guide or pivot restriction units each have at least one extension projecting radially and in the longitudinal direction of the screw beyond the spherical base shape of the screw head. The extensions form stops on their radial outer surfaces and are positioned to permit relative pivoting of the screw shaft and the area or receiving sleeve only in one pivoting plane, and to abut in a supporting manner against a radially inner circumferential side of the area or receiving sleeve during relative pivoting in another pivoting plane.

Abstract: A pedicle screw with a receiving sleeve and a screw head includes a distal pivoting section that can be or is pivotally inserted into the receiving sleeve and a proximal holding section that can be or is inserted in a fixed position in the receiving sleeve, which are integrally connected to one another, in particular are manufactured in one piece, via at least one preferably elastically and/or plastically deformable web in such a way that they can be pivoted relative to one another about a pivot axis extending transversely to a longitudinal axis of a screw.

Abstract: An implant system that includes a concave spherical-segment-shaped socket part and a corresponding convex spherical-segment-shaped joint part is provided. The joint part rests in the socket part, wherein at least three support elements that describe a spherical triangle or a spherical polygon are arranged on the surface of the joint part or on the surface of the socket part.

Abstract: A cluster system comprises a plurality of nodes that provides data-access service to a shared storage, each node having at least one failover partner node for taking over services of a node if the node fails. Each node may produce write logs for the shared storage and periodically send write logs at predetermined time intervals to a global device which stores write logs from each node. The global device may detect failure of a node by monitoring time intervals of when write logs are received from each node. Upon detection of a node failure, the global device may provide the write logs of the failed node to one or more partner nodes for performing the write logs on the shared storage. Write logs may be transmitted only between nodes and the global device to reduce data exchanges between nodes and conserving I/O resources of the nodes.

Abstract: A disk-less quorum device in a clustered storage system includes non-volatile memory to store status information regarding the cluster and each storage controller in the cluster. The quorum device maintains a bitmap, shared by the controllers in the cluster, in the non-volatile memory. The bitmap indicates the status of a write operation to any data block or parity block. A “dirty” data unit in the bitmap indicates that a write operation has been submitted but is not yet finished. Upon submitting a write request (to update a data block or a parity block) to the storage facility, a controller sets the corresponding data unit “dirty” in the bitmap. After receiving an acknowledgement from the storage facility indicating that the operation has been completed, the controller clears the corresponding data unit. If a controller fails during a write operation, another controller can use the bitmap to re-establish data consistency.
