Abstract: A surgical instrument includes a chassis, an outer tube having a proximal end operably coupled to the chassis, and an inner tube extending within the outer tube. The inner tube has a proximal end operably coupled to the chassis to allow slidable movement of the inner tube relative to the outer tube in response to a force imparted to a distal end of the inner tube, and such that frictional force imparted to an outer surface of the outer tube is not imparted to the inner member.

Abstract: In various examples, a deep neural network (DNN) is trained to accurately predict, in deployment, distances to objects and obstacles using image data alone. The DNN may be trained with ground truth data that is generated and encoded using sensor data from any number of depth predicting sensors, such as, without limitation, RADAR sensors, LIDAR sensors, and/or SONAR sensors. Camera adaptation algorithms may be used in various embodiments to adapt the DNN for use with image data generated by cameras with varying parameters—such as varying fields of view. In some examples, a post-processing safety bounds operation may be executed on the predictions of the DNN to ensure that the predictions fall within a safety-permissible range.

Abstract: Devices and techniques for continuous in-memory versioning are described herein. A memory subsystem includes a memory device configured to store a first data unit, a second data unit, and a third data unit, wherein the first, second, and third data units have a set of physical memory locations on the memory device, and metadata associated with the first, second, and third data units, the metadata including state information and a dirty commit timestamp; and a processing device, operatively coupled to the memory device, the processing device configured to: receive, from a host system, a first memory command associated with a logical memory address, the logical memory address mapped to the set of physical memory locations of the memory device; and in response to receiving the first memory command, perform a data operation on the first, second, or third data unit based on the state information and the dirty commit timestamp.

Abstract: Disclosed in some examples are systems, devices, machine-readable mediums, and methods for customizing an in-memory versioning mode for each memory location according to a predicted access behavior to optimize memory device performance. Usage data in a previous time period may be utilized along with policy rules to determine whether to configure a particular memory address as a zero copy or direct copy mode. For example, memory addresses that are read frequently may be configured as direct copy mode to reduce the read latency penalty. This improves the functioning of the memory system by reducing read latency for memory addresses that are frequently read but written to less frequently, and reduces write latency for memory locations that are frequently written to, but not read as frequently.

Abstract: The disclosure provides compounds of Formula (I) or a pharmaceutically acceptable salt thereof, wherein W1, W2, Y, Z, CS, R2, and R3 are as described herein. The compounds or their pharmaceutically acceptable salts can inhibit the G12C mutant of Kirsten rat sarcoma (KRAS) protein and are expected to have utility as therapeutic agents, for example, for treating cancer. The disclosure also provides pharmaceutical compositions which comprise compounds of Formula (I) or pharmaceutically acceptable salts thereof. The disclosure also relates to methods for use of the compounds or their pharmaceutically acceptable salts in the therapy and prophylaxis of cancer and for preparing pharmaceuticals for this purpose.

Abstract: The present invention relates to methods and compositions for transforming soybean, corn, cotton, or canola explants using spectinomycin as a selective agent for transformation of the explants. The method may further comprise treatment of the explants with cytokinin during the transformation and regeneration process.

Abstract: In one embodiment, a video frame is received from an external source, one or more users are extracted from the video frame, and user attendee data is generated based on the one or more extracted users and stored in a database. The user attendee data and video frame are transmitted to the client device and a communication session of the client device is updated based on the video frame and attendee data.

Abstract: In one embodiment, a method includes receiving a request from a first user for a content page; in response to the request, identifying at least one content page, wherein the content page is associated with a page identifier; identifying a plurality of content items based at least in part on a plurality of content features associated with the content page; ranking the plurality of content items based at least in part on a plurality of user features associated with the first user; and delivering to the first user, with the requested content page, one or more of the plurality of content items as recommendations to the first user based on the ranking of the content items.

Abstract: In one embodiment, a system includes one or more computing systems that implement a social networking environment containing a large number of heterogeneous objects type, each of the plurality of object types having varying features, the system implementing a generic object recommendation engine for scoring objects and recommending the objects to users of the social networking system. In particular embodiments, the user and content object features are fed as inputs into a heuristic model that generates an expected value for the content object and user. In particular embodiments, the object recommendation engine includes an online learner that may log a user's actions after the initial impression to determine the relatively degree of interest to the user.

Abstract: In one embodiment, video and audio data of a plurality of users is received from at least one external device and a speaking user is identified from at least one of the video and audio data.

Abstract: A social networking system presents advertisements and recommendation units to its users. The recommendation units suggest actions for the users to increase their engagement with the social networking system or otherwise interact with other users, while the social networking system receives revenue from advertisers for displaying advertisements based on bid values associated with the advertisements. The social networking system determines values for the advertisements and for the recommendation units, where the values are measured in a comparable fashion. This allows the system to rank and select the advertisements and recommendation units together in a unified auction model. For example, the social networking system uses a pacing value to determine values of recommendation units having a common unit of measurement with expected values of advertisements to the social networking system.

Abstract: A portable housing of a moving laser beam reader or an imaging reader is held by an operator in a handheld mode during electro-optical reading of symbols. A docking station supports the housing in a docked state when the housing is not in the handheld mode. At least one proximity sensor is supported by the housing and/or the docking station. The proximity sensor detects the operator's remoteness from the sensor to lock the housing to the docking station in the docked state, and detects the operator's proximity to the sensor to release the housing from the docking station.
