Abstract: Described herein are, among other things, techniques, devices, and systems for generating one or more trained machine-learning models used for generating content-item recommendations. Also described herein are techniques, devices, and systems for applying a consumption history of a particular user to the trained model(s) to generate score data indicating a correlation between each content-item title and the consumption history, as well as modifying this score data using one or more biasing factors for generating result data. In addition, the techniques, devices, and systems may use this result data, along with received user input, for determining an order in which to present one or more content items to the user. For example, this may include determining which content items to recommend to a user and in which order to do so.

Abstract: Methods of assessing wear of an electrical insulator and rail pad of an assembled rail fastening system utilize data from a 3D scan of the system to derive measurements of the system from which wear of the side post of the electrical insulator, or wear of the rail pad beneath the rail, may be assessed.

Abstract: A trained machine learning model(s) is used to determine scores (e.g., trust scores) for user accounts registered with a video game service, and the scores are used to match players together in multiplayer video game settings. In an example process, a computing system may access data associated with registered user accounts, provide the data as input to the trained machine learning model(s), and the trained machine learning model(s) generates the scores as output, which relate to probabilities of players behaving, or not behaving, in accordance with a particular behavior while playing a video game in multiplayer mode. Thereafter, subsets of logged-in user accounts executing a video game can be assigned to different matches based at least in part on the scores determined for those logged-in user accounts, and the video game is executed in the assigned match for each logged-in user account.

Abstract: The present disclosure relates, in general, to improved processes for the preparation of 4-{8-amino-3-[(2S)-1-(but-2-ynoyl)pyrrolidin-2-yl]imidazo[1,5-a]pyrazin-1-yl}-N-(pyridin-2-yl)-benzamide, particularly large-scale processes for manufacturing 4-{8-amino-3-[(2S)-1-(but-2-ynoyl)pyrrolidin-2-yl]imidazo[1,5-a]pyrazin-1-yl}-N-(pyridin-2-yl)benzamide and intermediates used in such processes.

Abstract: A system for tissue dissection and retraction is disclosed herein. A tissue dissection assembly generally comprises an elongate body shaft, an actuation member movable relative to the elongate body shaft, and at least one dissector arm member having at least a first end attached to the elongate body shaft, wherein the at least one dissector arm member is adapted to reconfigure within a plane from a low profile to an expanded profile when urged via the actuation member, and wherein the at least one dissector arm is further adapted to dissect tissue within the plane. In use, the assembly dissects tissue within the plane typically by advancing the elongate body shaft into the tissue region where the dissector arm member or members are then reconfigured within the plane from its low profile to its expanded profile to thereby dissect the tissue region along the plane.

Abstract: A system (100) for handling sheets of flexible material comprises: a plurality of releasable connectors (20) supported on a main carrier (110). The releasable connectors (20) are individually addressable so that when actuated a connector lifts or releases a sheet of flexible material. One or more end adjustment means is provided to vary at least one of: the orientation and/or the location of the connectors (20), with respect to a surface defined in three dimensions, such that in use the sheet of flexible material is placed in a precise user selected position on the three dimensional surface without the material creasing or wrinkling. An advantage of the present invention is that previously actuators were able to orient grippers to be normal to the surface of a cylinder; whereas the provision of parallel, flexible strips enables active surfaces to be positioned normal to the surface of complex surface, such as that defined by a cone.

Abstract: A system and method of removing turbulence from an image of a time ordered sequence of image frames. The method comprises removing effects of turbulence from a first image of the sequence to create an initial corrected image frame; determining a number of iterations required to achieve a desired turbulence removal for a subsequent image in the sequence and satisfy a latency constraint and an available memory capacity; and determining, based on the number of required iterations, a minimum set of image frames required to remove turbulence from the subsequent image. The minimum set of image frames comprises: a number of image frames of the sequence, a number of image frames generated in an intermediate iteration of turbulence removal and the initial corrected image frame. The method further comprises using the minimum set of image frames to remove turbulence from the subsequent image of the sequence.
