Abstract: Alert directives and focused alert directives allow a user to provide feedback to a behavioral recognition system to always or never publish an alert for certain events. Such an approach bypasses the normal publication methods of the behavioral recognition system yet does not obstruct the system's learning procedures.

Abstract: Techniques are disclosed for building a dictionary of words from combinations of symbols generated based on input data. A neuro-linguistic behavior recognition system includes a neuro-linguistic module that generates a linguistic model that describes data input from a source (e.g., video data, SCADA data, etc.). To generate words for the linguistic model, a lexical analyzer component in the neuro-linguistic module receives a stream of symbols, each symbol generated based on an ordered stream of normalized vectors generated from input data. The lexical analyzer component determines words from combinations of the symbols based on a hierarchical learning model having one or more levels. Each level indicates a length of the words to be identified at that level. Statistics are evaluated for the words identified at each level. The lexical analyzer component identifies one or more of the words having statistical significance.

Abstract: A multi-layer reconfigurable reflective intelligent surface (RIS). The RIS includes a unit-cell of a reconfigurable intelligent surface. The unit-cell includes a first layer composed of a conductive material and structured according to a sub-wavelength reflective pattern. The first layer reflects an impinging wave at a predetermined phase and steers the reflected impinging wave toward an intended receiver. The unit-cell includes a second layer composed of a first dielectric substrate material. Between the first and second layers, the unit-cell includes a middle layer composed of a second dielectric material having tunable dielectric properties. Tuning a dielectric constant of the second dielectric material modifies the predetermined phase of reflection of the impinging wave.

Abstract: Systems and methods for identifying Multisystem Inflammatory Syndrome in Children (MIS-C) may use various hematological parameters and combinations of hematological parameters. Such parameters and combinations may use monocyte distribution width (MVDW), though other parameters may also be used. Using this approach, area under curve values of 0.8 or greater may be achieved. Such parameters may also be used in treatment of MIS-C, including evaluation of status of hospitalized patients to determine when such patients may be safely discharged.

Abstract: Exemplary methods, apparatuses, and systems include a central controller receiving a request to generate a new encryption key for a security group to replace a current encryption key for the security group. The security group includes a plurality of hosts that each encrypt and decrypt communications using the current encryption key.
