Abstract: Organs-on-chips are microfluidic devices for culturing living cells in micrometer sized chambers in order to model physiological functions of tissues and organs. Engineered patterning and continuous fluid flow in these devices has allowed culturing of intestinal cells bearing physiologically relevant features and sustained exposure to bacteria while maintaining cellular viability, thereby allowing study of inflammatory bowl diseases. However, existing intestinal cells do not possess all physiologically relevant subtypes, do not possess the repertoire of genetic variations, or allow for study of other important cellular actors such as immune cells. Use of iPSC-derived epithelium, including IBD patient-specific cells, allows for superior disease modeling by capturing the multi-faceted nature of the disease.

Abstract: A payload support frame is adapted to suspend a payload from an unmanned aerial vehicle (UAV) during flight. The frame comprises at least one elongated rigid segment, at least one upper flexible segment at an upper end of the rigid segment, and at least one lower flexible segment at a lower end of the rigid segment. One or more of (a) the at least one rigid segment, (b) the at least one upper flexible segment, or (c) the at least one lower flexible segment comprise a dielectric material. The upper flexible segment is adapted to be selectively attachable, directly or indirectly, to the UAV. The lower flexible segment is adapted to be selectively attachable, directly or indirectly, to the payload.

Abstract: System, methods, and machine-readable media to facilitate monitoring and control of a railway maintenance assembly are disclosed. A railway workhead component monitor may be adapted to be disposed at a railway maintenance assembly. The railway workhead component monitor may be configured to perform one or a combination of the following. One or more conditions of at least a portion of the railway maintenance assembly may be monitored. Based at least in part on the monitoring, a plurality of monitoring data corresponding to operations of the railway maintenance assembly may be stored. Reporting data may be generated based at least in part on the stored plurality of monitoring data. A wireless communication may be transmitted toward a railway device controller that is remote from the railway maintenance assembly, the wireless communication including the reporting data.

Abstract: Dynamic timers are determined using machine learning. The timers are used to control the amount of time that new data transaction requests wait before being processed by a data transaction processing system. The timers are adjusted based on changing conditions within the data transaction processing system. The dynamic timers may be determined using machine learning inference based on feature values calculated as a result of the changing conditions.

Abstract: A computer system is provided that is programmed to select feature sets from a large number of features. Features for a set are selected based on metagradient information returned from a machine learning process that has been performed on an earlier selected feature set. The process can iterate until a selected feature set converges or otherwise meets or exceeds a given threshold.

Abstract: The present disclosure is directed to simulating patterns of reflected radar energy off of reference objects using motion data associated with these reference objects. This motion data may identify start times, start locations, end times, and end locations of a limited number reference objects in a set of discrete scenes. Each of these discrete scenes may also have a same time duration. Motion of these specific objects between a start time and an end time of each discrete scene may be interpolated. Once the locations of the objects are interpolated for a given scene, simulations may be performed to estimate the appearance of reflected radar signals that would be received by a radar apparatus. These simulations may identify patterns of reflected radar energy after radar signals have been emitted from the radar apparatus and these patterns may then be provided to train a machine learning apparatus.
