Abstract: Embodiments of the present disclosure are configured to assess the severity of a blockage in a vessel and, in particular, a stenosis in a blood vessel. In some particular embodiments, the devices, systems, and methods of the present disclosure are configured to assess the severity of a stenosis in the coronary arteries without the administration of a hyperemic agent.

Abstract: Embodiments of the present disclosure provide to techniques for automatically grouping software applications based on their technical patterns/characteristics (i.e., technical facets) via machine learning (ML) algorithms. For instance, a first set of software applications that exhibit a high prevalence of one or more first technical facets may be grouped into a first category, a second set of software applications that exhibit a high prevalence of one or more second technical facets may be grouped into a second category, and so on. Once grouped into categories, the software applications in a given category may be assessed, analyzed, and/or processed together for various purposes.

Abstract: Disclosed herein are systems and methods related to reducing or making more efficient handovers from one cell to another cell in a communications network. The method includes receiving mobility data for a device being serviced by a first cell, classifying the device based on the mobility data to yield a classification and making a handoff decision when handing off the device from the first cell to a second cell based at least in part on the classification. An example of the mobility data is a speed at which the device is moving or time a device is in a cell.

Abstract: A method comprises storing first transaction data for a first transaction producing a first version of a first dataset, second transaction data for a second transaction transforming a first version of the first dataset to a second version of the first dataset, and third transaction data for a third transaction transforming the second version of the first dataset to a third version of the first dataset; storing dependency information indicating a first dependency of the third transaction on the second transaction and a second dependency of the second transaction on the first transaction; receiving a first instruction to revoke a first permission of a first user to access the second version of the first dataset; automatically revoking a certain permission of the first user to access the third version of the first dataset based on the dependency information.

Abstract: Provided are computing systems, methods, and platforms that automatically produce production-ready machine learning models and deployment pipelines from minimal input information such as a raw training dataset. In particular, one example computing system can import a training dataset associated with a user. The computing system can execute an origination machine learning pipeline to perform a model architecture search that selects and trains a machine learning model for the training dataset. Execution of the origination machine learning pipeline can also result in generation of a deployment machine learning pipeline configured to enable deployment of the machine learning model (e.g., running the machine learning model to produce inferences and/or optionally other tasks such as re-training and/or re-tuning the model).

Abstract: A method for treating process material using a plurality of autoclaves. The method includes: introducing steam into a hollow interior of a first autoclave; increasing the temperature within the hollow interior of the first autoclave by adding heat to the hollow interior of the first autoclave using an indirect heat source; reducing the temperature and pressure within the hollow interior of the first autoclave by flashing a portion of the steam within the hollow interior of the first autoclave to a second autoclave; increasing the temperature within the hollow interior of the first autoclave by continuing to add heat to the hollow interior of first autoclave using the indirect heat source; and reducing a moisture content of a process material in the hollow interior of the first autoclave to a predetermined value by venting a remaining portion of the steam from the first autoclave into a third autoclave.

Abstract: A method for preparing a purified styrene composition is provided. The method includes providing a crude composition and subjecting the crude composition to at least one crystallization step. The crude composition contains 70% by weight or more styrene based on the total weight of the crude composition. The at least one crystallization step comprises at least one of a static crystallization stage and a dynamic crystallization stage. The crude composition contains at least one impurity selected from the group consisting of: color inducing species, oxygenates, sulfur species, alpha-methylstyrene, and mixtures thereof.

Abstract: A repeater for maintaining wireless line of sight communications. The repeater is autonomously repositional in both absolute location and azimuthal orientation. The repeater has at least two vibratory motors, or other vibration sources, which provide oscillations to depending legs against a support surface. By selectively operating one or more of the vibration sources together or independently, the repeater may be moved as helpful to maintain line of sight communication with another repeater or other operational hardware. A command signal from a remote base station controls the locomotion of the repeater to provide both a change in absolute position relative to the surroundings and a rotational change in azimuthal orientation as necessary to maintain communication under dynamic conditions.

Abstract: A neural network has a synapse module with a plurality of synapses. A steering circuit is coupled to an output of the synapse module. A plurality of processing elements is coupled to an output of the steering circuit. Each of the processing elements share the synapses of the synapse module through the steering circuit. A first processing element of the plurality of processing elements receives a first current from a first output of the first synapse and a second current from a second output of the first synapse through the steering circuit. The first processing element has a first capacitor receiving the first current, and a second capacitor receiving the second current to generate a pulse width modulate output signal of the first processing element. A polarity inversion circuit is coupled for receiving the first current and reversing flow direction of the first current.

Abstract: A portable communication system for use in hostile and unknown environments. The system has a base station for control by an operator. The base station dispatches one or more unmanned drones into the hostile environment, where a forward agent, such a robot or investigative person can approach a suspected threat. Each drone has a payload of repeaters to be delivered as necessary to maintain line of sight communication from the forward agent back to the base station. Once delivered, the repeaters are mobile and can autonomously reposition to maintain or optimize line of sight communication. Communications from the forward agent back to the base station are then interpreted and analyzed for further action.
