Abstract: A network of hang avoidance controllers and components which provide layer or scope based hang avoidance mechanisms in a distributed computing system is described. The detection of hang avoidance conditions and activation of the hang avoidance mechanisms are implemented on various limited scopes in the computing system, which prevent unnecessary system wide interruptions to avoid potential hangs in the system.

Abstract: A computer system includes a processor core and a memory system in signal communication with the processor core. The memory system includes a first cache and a second cache. The first cache is arranged at a first level of a hierarchy in the memory system and is configured to store a plurality of first-cache entries. The second cache is arranged at a second level of the hierarchy that is lower than the first level, and stores a plurality of second-cache entries. The first cache maintains a directory that contains information for each of the first-cache entries. The second cache maintains a shadow pointer directory (SPD) that includes one or more SPD entries that maps each of the first-cache entries to a corresponding second cache entry at a lower-level cache location.

Abstract: Methods, devices and systems are disclosed for inter-app communications between software applications on a mobile communications device. In one aspect, a computer-readable medium on a mobile computing device comprising an inter-application communication data structure to facilitate transitioning and distributing data between software applications in a shared app group for an operating system of the mobile computing device includes a scheme field of the data structure providing a scheme id associated with a target software app to transition to from a source software app, wherein the scheme id is listed on a scheme list stored with the source software app; and a payload field of the data structure providing data and/or an identification where to access data in a shared file system accessible to the software applications in the shared app group, wherein the payload field is encrypted.

Abstract: Embodiments are for processor cross-core cache line contention management. A computer-implemented method includes sending a cross-invalidate command to one or more caches based on receiving a cache state change request for a cache line in a symmetric multiprocessing system and determining a retry delay based on receiving a cross-invalidate reject response from at least one of the one or more caches. The computer-implemented method also includes waiting until a retry delay period associated with the retry delay has elapsed to resend the cross-invalidate command to the one or more caches and granting the cache state change request for the cache line based on receiving a cross-invalidate accept response from the one or more caches.

Abstract: A lower-level cache managing cross-core invalidation (XI) snapshots in a shared-memory multiprocessing system, wherein the management of XI snapshots reduces an amount of required snapshots while allowing shared lower-level caches, comprising: the lower-level cache maintaining respective response sync state for at least one processor in a plurality of processors signifying that a line may have been changed by another processor since last fetched by a requesting processor.

Abstract: According to one method for using machine learning in detecting drug diversion, the method comprises receiving, as input, an observed drug dispensation amount associated with a drug dispensation event related to a drug provider along with other drug dispensation event data, wherein the drug dispensation event data comprises drug provider information, procedure information, and patient information; generating, using a trained drug diversion detection algorithm and the drug dispensation event data, an expected drug dispensation amount associated with the drug dispensation event and determining, using the observed drug dispensation amount and the expected drug dispensation amount, whether the observed drug dispensation amount is aberrant, wherein the drug diversion detection algorithm includes at least one machine learning algorithm and is trained using one or more data sets associated with related drug dispensation events; and outputting, by the drug diversion detection algorithm, information indicating that th

Abstract: Systems and methods for performing long-term kinematic tracking of an animal subject are provided. Chronically-affixed motion capture markers including a tissue engaging feature and a reflective marker are described, the motion capture markers enabling long-term motion capture recording of an animal subject. A method of determining a three-dimensional pose of a subject using a trained statistical model configured to generate landmark position data associated with the three-dimensional pose of the animal subject. The method includes using projective geometry to generate three-dimensional image volumes as input to the trained statistical model. Further, a method for profiling a subject’s physical behavior over a period of time by applying clustering to information indicative of movement of the subject over the period of time is described.
