Abstract: A fixed depth skin flap elevator device is provided. The device includes an elongated handle having a proximal end and a distal end. The device further includes an upper arm and lower arm mounted to, so as to extend longitudinally from, the distal end of the handle. The upper arm overlays the lower arm. At least free ends of the upper and lower arms are spaced apart by a distance which is equal to a pre-determined cutting depth. A blade is supported on the lower arm at about its free end. Translation of at least the lower arm within a tissue interior results in separation of a deeper tissue from a surface tissue at a pre-determined cutting depth to form an undermined skin and subcutaneous surface tissue flap of uniform thickness. A method of using the device is also provided.

Abstract: A method is a described for constructing a hearing aid shell that comprises a combination of hard and soft materials. In one embodiment, 3D printing is combined with conventional mold/casting methods so that a first shell portion made of a hard material and a mold for a second shell portion are 3D printed. The mold is then filled with a soft material which is allowed to set to form the second shell portion, and the first and second shell portions are adhesively attached.

Abstract: An instruction stream includes a transactional code region. The transactional code region includes a latent modification instruction (LMI), a next sequential instruction (NSI) following the LMI, and a set of target instructions following the NSI in program order. Each target instruction has an associated function, and the LMI at least partially specifies a substitute function for the associated function. A processor executes the LMI, the NSI, and at least one of the target instructions, employing the substitute function at least partially specified by the LMI. The LMI, the NSI, and the target instructions may be executed by the processor in sequential program order or out of order.

Abstract: A plurality of different hosted services each includes enabling logic that enables a set of actions. Usage data for a plurality of different tenants are accessed and actions are grouped into features based upon underlying enabling logic. A correlation score between features is identified based on tenant usage data for those features. A tenant under analysis is selected and usage data for the tenant under analysis is used to identify related features that the tenant under analysis is not using, based upon the correlation scores for the features. An output system is controlled to surface the related features for the tenant under analysis.

Abstract: A surgical suture having enhanced visual characteristics is provided. The suture has a suture filament operatively coupled to a suture needle. The suture filament includes a useful segment and a terminal segment. The terminal segment is located at a first end of the filament. The useful segment extends substantially from the terminal segment to a second end of the filament. The terminal segment is of a length of the filament that is left-over after a substantially last formable suture knot is formed using the useful segment. After the last formable suture knot is formed, the terminal segment is removed from the useful segment along with the suture needle for disposal. In order to enable visual location of the terminal segment after the same has been separated from the useful segment, the filament is treated such that that the terminal segment has distinctive contrasting light frequency characteristics.

Abstract: A transaction is detected. The transaction has a begin-transaction indication and an end-transaction indication. If it is determined that the begin-transaction indication is not a no-speculation indication, then the transaction is processed.

Abstract: Providing control over processing of a prefetch request in response to conditions in a receiver of the prefetch request and to conditions in a source of the prefetch request. A processor generates a prefetch request and a tag that dictates processing the prefect request. A processor sends the prefetch request and the tag to a second processor. A processor generates a conflict indication based on whether a concurrent processing of the prefetch request and an atomic transaction by the second processor would generate a conflict with a memory access that is associated with the atomic transaction. Based on an analysis of the conflict indication and the tag, a processor processes (i) either the prefetch request or the atomic transaction, or (ii) both the prefetch request and the atomic transaction.

Abstract: Processing prefetch memory operations and transactions. A local processor receives a write prefetch request from a remote processor.

The write prefetch request is executed in response to a determination that the priority of the write prefetch request is greater than the priority of a pending transaction. Prefetch data produced by execution of the write prefetch request is provided to the remote processor.

Abstract: In a transactional memory environment including a first processor and one or more additional processors, a computer-implemented method includes identifying a memory location and sending a probe request from the first processor to the additional processors. The probe request includes the memory location. The computer implemented method further includes generating, by each additional processor, an indication including whether the memory location is in use for a transaction by the additional processor. The computer-implemented method further includes sending the indication from each additional processor to the first processor and proceeding, by the first processor, based on the indication.

Abstract: A transaction within a computer program or computer application comprises program instructions performing multiple store operations that appear to run and complete as a single, atomic operation. The program instructions forming a current transaction comprise a transaction begin indicator, a plurality of instructions (e.g., store operations), and a transaction end indicator. A near-end of transaction indicator is triggered based on a speculative look ahead operation such that an interfering transaction requiring a halt operation may be delayed to allow the current transaction to end. A halt operation, also referred to as an abort operation, as used herein refers to an operation responsive to a condition where two transactions have been detected to interfere where at least one transaction must be aborted and the state of the processor is reset to the state at the beginning of the aborted transaction by performing a rollback.
