An improved method, system, and a computer program storage device (e.g., including software embodied on a magnetic, electrical, optical, or other storage device) for management of compressed main memory allocation and utilization which can avoid system abends or inefficient operation that would otherwise result. One feature reduces (and ultimately eliminates) all unessential processing as the amount of available storage decreases to a point low enough to threaten a system abend. In another example, the amount of current memory usage is determined as well as one or more of: an estimate of an amount of allocated but unused memory; a determination of the amount of memory required for outstanding I/O requests. The compressed memory is managed as a function of the current memory usage and one or more of the other measured or estimated quantities. The compressed memory can be managed by maintaining a set of dynamic thresholds; estimating the amount of storage that can easily be freed (used but available) and the amount of storage that is committed (allocated but unused). The estimate of committed storage can include: the current storage utilization; and an estimate of storage committed to new pages (based on the number of new pages granted), the times at which this was done, the estimated compression ratio, and estimates of residency times in the cache.

A retractor for use in surgical operations comprises a pair of blade assemblies which are adapted to open about a set of axes that are not parallel to a third spatial axis. The retractor further comprises a pair of arms, which are adapted to move the pair of blade assemblies apart from one another in the third spatial axis. In operation, the blade assemblies are closed to assume a low profile, inserted into a relatively small incision, and stretched apart from each other, thereby stretching the skin about the incision to form an aperture longer than the incision. The blade assemblies are then opened by rotating the blades about the set of axes, thereby stretching the skin around the incision in a second direction that is substantially perpendicular to the first direction (i.e. the direction of the incision.) The retractor thus forms an aperture for passage of surgical instruments and viewing of the surgical field by surgical personnel. In some embodiments, the retractor features a pair of removable handles that may be removed from the arms during surgery in order to afford the surgeon improved space management about the incision. In specific embodiments, the invention provides a method of performing an operation, e.g. a spinal operation, on a patient using the disclosed retractor.

Publishers define relationships between their own content items (e.g., World Wide Web pages) and content items created or maintained by other publishers. A central namespace manager provides grouping labels that publishers insert into their content items. Content items having matching grouping labels are identified as related. Different classes of grouping labels can be used to define different types of relationships, and multiple classes of grouping labels can co-exist. Grouping labels are made available to an information server such as a search server, which uses the labels in identifying content items related to a currently displayed content item.

A method of symbol combining and incremental redundancy for link adaptation and code space management was proposed. In order to reduce constraints on the Walsh codes allocation, MCS level change, as well as frame duration change for the initial transmission and re-transmissions, a “rate matching” stage is proposed between the Turbo encoder and block interleaver on the transmitter. In the initial transmission, the Turbo encoded symbols are interleaved with or without any puncturing or repeating (i.e. puncture/repeat factor is set to 1). The coded symbols are also stored in the memory for possible retransmissions. In the re-transmission, the transmitter first determines the number of Walsh codes available for this user and MCS level and frame duration according to the C/I feedback values from MS. The stored coded symbols are then punctured or repeated according to “rate matching factors”. On the receiver side, “rate matching factors” can be derived from the number of code channels, MCS level and frame duration of current re-transmissions and initial transmission. Then, de-puncturing/de-repeating is performed before coded symbol combining. A similar rate matching based IR/symbol combining scheme can be used to design different IR using different rate matching algorithms. It has low implementation complexity and is easily made backward compatible.

A framework for in-memory space management for content management database systems is provided. A per-instance in-memory dispenser is partitioned. An incoming transaction takes a latch on a partition and obtains sufficient block usage to perform and complete the transaction. Generating redo information is decoupled from transaction level processing and, instead, is performed when block requests are loaded into the in-memory dispenser or synced therefrom to a per-instance on-disk structure.

Method and system for performing a namespace operation in a distributed file system. The file system is disposed on a plurality of partition servers, and each partition server controls access to a subset of hierarchically-related, shared storage objects. Each namespace operation involves a namespace object and a target object that are part of the shared storage objects. Namespace operations received at each partition server are serialized. In response to an unlink namespace operation, a reference in the namespace object to the target object is removed, and after removal the target object is modified in accordance with the unlink operation. In response to a link operation, the target object is modified consistent with the link operation. After modification of the target object, a reference to the target object is inserted in the namespace object.
