Next, the computer system may perform different remedial actions for a first group of individuals in the plurality of individuals having the results where the levels of uncertainty are within the at least one threshold range and a second group of individuals in the plurality of individuals having the results where the levels of uncertainty are outside of the at least one threshold range.

Abstract: The representative embodiments discussed in the present disclosure relate to techniques with which data packet loss, such as Transmission Control Protocol (TCP) packet loss, may be detected. More specifically, in some embodiments, by detecting a TCP packet with an enabled selective acknowledgement (SACK) signal, the loss (e.g., drop) of an additional TCP packet may be determined. Moreover, using information included in the detected TCP packet, an operational efficiency of a cloud computing system and/or a component of the cloud computing system may be determined.

Abstract: In a method and system for viewer interaction with streaming media, a scene from a media presentation is displayed with a broadcasting device that includes an operating system level broadcaster interface overlay. The overlay generates an image frame from the scene. The image frame is sent to a viewer device. Viewer interaction parameters are received from a viewing device and a viewer interaction is displayed over a subsequent scene from the media presentation with the broadcaster interface overlay. On a viewing device an image frame from the media presentation is received from the broadcasting device. An operating system level viewer interface overlay is generated over the image frame and the image frame of the media presentation is displayed. Viewer interaction parameters are generated from a viewer interaction with the operating system level viewer interface overlay and sent to the broadcasting device.

The stress relief structure includes an end opening defined in a radial outer surface of the mounting rail, a slot defined through the rail thickness of the mounting rail and coupled to the end opening, and an oblong opening defined through the rail thickness of the mounting rail and coupled to a radial inner end of the slot. The oblong opening is arranged asymmetrically in a circumferential direction relative to the slot to relieve stress where prevalent in the mounting rail.

Abstract: A machine learning system predicts a physicochemical property (e.g., lipophilicity) of candidate small molecules for pharmaceuticals. A machine learning model is constructed that is trained from a database of small molecule physicochemical properties including known lipophilicity and known retention time in a liquid chromatography column to create a learned association between lipophilicity and liquid chromatography retention time. A candidate small molecule having unknown lipophilicity and unknown retention time is applied to a liquid chromatography column. The retention time of the candidate small molecule in the liquid chromatography column is measured. The measured retention time in the liquid chromatography column is applied to the machine learning model to obtain lipophilicity for the candidate small molecule. One or more candidate small molecules having a lipophilicity value from approximately 1 to approximately 3 are selected from the machine learning model.

Abstract: Various embodiments include a turbine blade having an airfoil with a tip shroud having a forwardmost tip rail having one or more pressure side and suction side bevel surfaces and pressure side and suction side scallop surfaces. The surfaces have a nominal profile substantially in accordance Cartesian coordinate values of X, Y and Z set forth in various tables herein. The Cartesian coordinate values are non-dimensional values of from 0% to 100% convertible to distances by multiplying the values by a tip rail length expressed in units of distance. The X, Y and Z values are connected by smooth continuing arcs that are joined smoothly with one another to form the nominal profile that defines the suction side scallop surface, the pressure side scallop surface, the suction side bevel surface, or the pressure side bevel surface.

Abstract: Provided herein are systems and methods for automated identification of volumes of interest in volumetric brain images using artificial intelligence (AI) enhanced imaging to diagnose and treat acute stroke. The methods can include receiving image data of a brain having header data and voxel values that represent an interruption in blood supply of the brain when imaged, extracting the header data from the image data, populating an array of cells with the voxel values, applying a segmenting analysis to the array to generate a segmented array, applying a morphological neighborhood analysis to the segmented array to generate a features relationship array, where the features relationship array includes features of interest in the brain indicative of stroke, identifying three-dimensional (3D) connected volumes of interest in the features relationship array, and generating output, for display at a user device, indicating the identified 3D volumes of interest.

Abstract: A system and method for automatically detecting misinformation is disclosed. The misinformation detection system is implemented using a cross-stitch based semi-supervised end-to-end neural attention model which is configured to leverage the large amount of unlabeled data that is available. In one embodiment, the model can at least partially generalize and identify emerging misinformation as it learns from an array of relevant external knowledge. Embodiments of the proposed system rely on heterogeneous information such as a social media post's text content, user details, and activity around the post, as well as external knowledge from the web, to identify whether the content includes misinformation. The results of the model are produced via an attention mechanism.

Abstract: A turbine blade tip shroud has a first cutter tooth extending from a tip rail from one of the upstream side and the downstream side of the tip rail and adjacent the leading edge of the body. The tip shroud also includes a second cutter tooth extending from the tip rail from the other side of the tip rail at a position axially distant from the first cutter tooth. The cutter teeth are thus axially offset. The tip shroud can be initially manufactured with this shape or may be modified from a used tip shroud having, for example, opposing cutter teeth near a leading edge of a body of the tip shroud. Various tip shroud surface profiles, which are expressed in terms of Cartesian coordinates, are also provided.

Abstract: A packaging sizer can receive and segment packaging into two or more segments. The packaging sizer can receive the packaging on a conveyance surface and convey the packaging to a position for segmenting. A segmenting assembly can segment the packaging to form two or more segments. The resulting segments can be directed in different directions for different purposes. For example, one or more of the segments can be removed from the packaging sizer and one or more segments can be moved to a position for manipulation by a packaging manipulator.
