Abstract: The present invention relates to rigid structures and composite materials thereof for providing radiation attenuation/shielding. Some embodiments pertain to a radiation shielding apparatus including: a plurality of positionable radiation-shielding stacks of tiles. The stacks are subsequently and adjacently arranged in a contiguous configuration. A tile positioning mechanism allows movement of tiles within a stack between a stacked (retracted) position and an extended position. In the extended position, the tiles of each of the plurality of radiation shielding stacks at least partially overlap tiles of subsequent and adjacent tile stack at corresponding opposing side-margins thereof.

Abstract: Lighting systems combine UV-A and white light with an adjustable CCT value so that any adverse effects from the UV-A radiation are mitigated—that is, tunable adjustments to the output of the non-UV LEDs, or to all of the LEDs, result in an overall mixed output conforming to a target CCT value.

Abstract: Embodiments of the present disclosure provide systems, methods, and non-transitory computer storage media for detecting abnormal behavior of device in an enterprise network based on an analysis of behavioral information of the device's neighbors in network. At a high level, embodiments of the present disclosure employ a hive-mind approach to determine anomalous behavior of a device in a network based on analyzing behavior information reported by neighboring devices within the network. Embodiments identify that a device is alive and connected within the network based on multiple neighboring devices reporting behavioral information about the device; however, the device may be dysfunctional and failing to report its own information. By aggregating and analyzing behavioral information of a device based on the reporting information of its neighboring devices, embodiments of the present disclosure are able to determine whether a device is healthy even when the device is unable to report its own information.

Abstract: The techniques disclosed herein enable systems to train a machine learning model to classify malicious command line strings and select anomalous and uncertain samples for analysis. To train the machine learning model, a system receives a labeled data set containing command line inputs that are known to be malicious or benign. Utilizing a term embedding model, the system can generate aggregated numerical representations of the command line inputs for analysis by the machine learning model. The aggregated numerical representations can include various information such as term scores that represent a probability that an individual term of the command line string is malicious as well as numerical representations of the individual terms. The system can subsequently provide the aggregated numerical representations to the machine learning model for analysis. Based on the aggregated numerical representations, the machine learning model can learn to distinguish malicious command line inputs from benign inputs.

Abstract: An assembly can comprise a prosthetic valve comprising a radially expandable and compressible frame and a rotatable screw connected to the frame, where the screw comprises a screw head having an annular bore with internal threads, and where the screw is rotatable to radially expand the frame. The assembly further comprises a delivery apparatus releasably coupled to the screw, the delivery apparatus comprising a first shaft and a first head disposed at an end of the first shaft, the first head comprising external threads configured to engage with the internal threads of the screw head, and a second shaft that is coaxial with and surrounds the first shaft, the second shaft comprising a second head disposed at an end of the second shaft. The second head is configured to releasably engage with an exterior surface of the screw head and rotate the screw.

Abstract: An oral care implement including a handle and an oral care refill head. The handle has a gripping portion, an engagement component coupled to a distal end of the gripping portion, and a stem. The engagement component includes a plate portion and a first engagement feature. The stem extends through an opening in the engagement component and protrudes from the plate portion. The oral care refill head includes an oral care treatment portion and a sleeve portion. The sleeve portion has an inner surface that defines a sleeve cavity having a cavity axis and a second engagement feature. When the oral care refill head is detachably coupled to the handle, the first and second engagement features mate with one another to at least one of: (1) position the oral care refill head and the handle in an operational alignment; and (2) lock the oral care refill head to the handle.
