Abstract: A system and a method are disclosed for recommending a set of actions to be performed to improve a target performance metric of a client application. An action recommendation system receives the target performance metric from a user associated with the client application. The action recommendation system determines features of the client application describing characteristics and performance history of the client application. The features of the client application and the target performance metric is provided as input to a machine learning model that outputs sets of target features that are likely to result in improvement for the target performance metric. The action recommendation system ranks the sets of target features and selects one of the sets based on the ranking. The action recommendation system determines a set of recommended actions based on the selected set of target features and presents the set of recommended actions to the user.

Abstract: This disclosure describes techniques for distributed storage of files that represent video content across different storage tiers to reduce the amount of computing resources used to store the files, while maintaining a low latency when responding to user requests to stream the video content. Video streaming services support the streaming of video content at different resolutions to support various user devices and/or user preferences. To provide streaming of a particular video content item at different resolutions, the video streaming services may store multiple files that represent the video content item for the different resolutions and stream at different bitrates to user devices. The techniques described herein include storing files configured to stream a video content item at different bitrates (and for different display resolutions) in a tiered storage structure to reduce the amount of computing resources taken to store the files.

Abstract: Devices, systems and methods are described herein to provide improved steerability for delivering a prosthesis to a body location, for example, for delivering a replacement mitral valve to a native mitral valve location. Disclosed are a number of features that can improve steerability or release of the prosthesis into the body location.

Abstract: Embodiments of the provided technology relate to methods, devices, and systems that drive a transfer of the digital profile of residual limb contours to a thermoplastic article such as a prosthetic socket strut. A method of reforming a thermoplastic article to assume a desired shape, such as a contour that replicates or is complementary to the contour of a body portion, may include heating a thermoplastic article to render the article malleable. The method may further include placing the thermoplastic article against a molding surface having a desired shape that replicates the portion of the body part. Next, the thermoplastic article may be pressed against the molding surface with a compliant molding press to reform at least a portion of the article into the desired shape. The reformed thermoplastic article may then be removed from the molding surface, the article retaining the desired shape after removal.

Abstract: An osseointegrated abutment support socket for a residual limb in which an osseointegrated abutment has been implanted is described. The osseointegrated abutment support socket may include a distal socket base assembly, multiple longitudinal struts and a percutaneous site protector. The distal socket base assembly may include a base plate, a collar extending proximally from the base plate and forming a receptacle for receiving a distal end of the osseointegrated abutment, and a strut support ring disposed around the collar. The struts are connected at their distal ends to the strut support ring and extend proximally upward. The percutaneous site protector contacts a distal surface of the residual limb near a percutaneous site where the distal end of the osseointegrated abutment exits the residual limb.

Abstract: An intra-frame positioning sling may be disposed internally within a prosthetic socket frame. The sling may include one or more proximal suspension portions adapted to suspend from a proximal aspect of the frame and a tensioning system. The sling may include a first longitudinal side with one or more proximal suspension portions and an opposite longitudinal side that includes the residual limb interfacing or force application portion of the sling. When the tensioning system is tensioned, the sling is pulled toward the first longitudinal side of the prosthetic socket frame. A set of two positioning slings may be rigged in a transfemoral prosthetic socket frame; one sling applies force on a medial side of a hosted residual limb, and the other sling applies force on the lateral side.
