Abstract: An isolation valve system includes a well string having an isolation valve including a ball rotatably mounted to a pair of inserts for rotation about a fixed axis, an arm coupled to the ball at a position offset from the fixed axis, and a mandrel connected to an actuation end of the arm, the mandrel and the actuation end of the arm being disposed uphole of the ball. Via the actuation end of the arm, the mandrel forces rotation of the ball from a closed position to an open position by moving in a linear direction away from the ball, which allows flow of fluid along a through hole of the ball.

Abstract: In some implementations, a computing device may perform a method for providing a unified pipeline for media metadata to converge disparate schemas and data structures into a global unified graph. The method includes receiving media metadata from disparate media sources that may each have a different metadata schema that defines the structure and attributes of the metadata provided by each media source. The computing device may compare media metadata received from the different media sources to determine that metadata received from the different media sources correspond to similar, or the same, media entities (e.g., songs, movies, books, etc.). The metadata for the similar media entities may then be combined into a global unified graph that may include metadata attributes and/or values of the metadata received from the various media sources.

Abstract: A system associated with quantifying a density level of tumor-infiltrating lymphocytes, based on prediction of reconstructed TIL information associated with tumoral tissue image data during pathology analysis of the tissue image data is disclosed. The system receives digitized diagnostic and stained whole-slide image data related to tissue of a particular type of tumoral data. Defined are regions of interest that represents a portion of, or a full image of the whole-slide image data. The image data is encoded into segmented data portions based on convolutional autoencoding of objects associated with the collection of image data. The density of tumor-infiltrating lymphocytes is determined of bounded segmented data portions for respective classification of the regions of interest. A classification label is assigned to the regions of interest. It is determined whether an assigned classification label is above a pre-determined threshold probability value of lymphocyte infiltrated.

An example engine fan case includes an outer band and an inner band, the outer band and the inner band connected using a double-walled vane, the vane including openings to pass cooling air flow from the outer band to an airfoil of the fairing, and an end segment seal, the seal formed on an edge of the fairing using an auxetic material.

Abstract: Presented here is a system and method to record images having varying zoom levels using a lens having a substantially fixed zoom level. The resulting image can have varying zoom levels and can be of high quality. The light sensor recording the image can have a resolution higher than the desired resolution of the resulting image. The high resolution of the light sensor allows digital zooming, i.e., cropping of the image. The light sensor can operate in two modes, where each mode produces varying resolutions of the resulting image. Operating the light sensor in the mode producing a high resolution of the resulting image, however, does not produce images of satisfactory quality in low light conditions, and the light sensor may need to be switched between the first and the second mode depending on the zoom level and the lighting conditions.

One embodiment of the present invention is a method that includes directing, by a first Session Border Controller (SBC), a first media call flow of a first call through a first media content processing entity to a second SBC, detecting, at one of said first or second SBCs, a status condition indicative of a failure condition for the first media content processing entity, and redirecting, by the SBC that detects the status condition indicative of a failure condition, the first media call flow for the first call so that the first media call flow passes through a second media content processing entity instead of through the first media content processing entity without terminating the first call.

Abstract: Systems and methods of improving the operation of a transaction network and transaction network devices is disclosed. A transaction network host may comprise various modules and engines as discussed herein wherein the probability that a transaction is a business or personal transaction may be evaluated for establishing proper usage of differentiated transaction instruments according to their proper purposes. For instance, a probable personal transaction may be identified as being associated with a business-oriented transaction card, whereby the transaction network may tailor the handling of the transaction, such as by denying it, whereby the transaction network may actively deter misuse of transaction products whereby the transaction network more properly functions according to approved parameters.
