    Abstract: A system and associated method for isolating intended radiation signals for determining target characteristics includes multiple detectors for detecting radiation signals having varying energies, delay modules for delaying the detected radiation signals and a discriminator associated with the multiple detectors for determining if detected radiation signals include unintended radiation signals, e.g., x-rays, and provided blanking signals to a switch in order to effectively remove the unintended radiation signals from the data that is presented to the processor for determining target characteristics.

    Abstract: The invention provides a set of mechanisms by which a wireless mobile mesh node equipped with a directional antenna may self form and self adapt its steady-state communications schedule. A link establishment handshake is carried out over an ongoing subtemplate-based discovery scan. During time not reserved for steady-state communications with previously discovered neighbors, nodes continue to search for an establish links with new neighbors. Initial and subsequent bandwidth allocation protocols may be utilized to allow peer nodes to coordinate communication opportunities between the peer nodes without impacting or having knowledge about reservations for communications with other peers. The link establishment and initial bandwidth allocation protocols may be piggy-backed for readily establishing an initial steady-state schedule with a peer upon link establishment without impact on previous steady state reservations by other nodes or on ongoing link establishment attempts elsewhere.

    Abstract: Data can be scanned using a network managed appliance. The network managed appliance may integrate commercial hardware elements connected through a basic or simplified operating system environment expressly developed for the appliance, thus being more malware resistant and less vulnerable to attacks from the scanned data or other sources. The network managed appliance may be a self-contained apparatus with an integrated chassis, designed and configured as “single-purpose” device. Such appliances may be connected to an appliance management network including central management servers in communication with appliances in remote locations. The central management servers may ensure that scanning software and the definitions lists for each of the appliances are current and match an enterprise-approved configuration.

    Abstract: Ridge Regression for Rapid Class Augmentation (R3CA), a regularized version of the XRCA incremental learning algorithm, implements an unconstrained, recursive least-squares (RLS) style of optimization that incorporates knowledge of all the past training examples into each optimization step by recursively computing an IFCM in a single multi-class prediction head. The single multi-class prediction head receives class token feature vectors from a pretrained, self-supervised, vision transformer model and is able to achieve the same optimal performance as a non-incrementally trained classifier in a jointly optimal manner over a set of increasing classes. R3CA excels at low sample incremental learning applications.

    Abstract: An acoustic vector sensor (“AVS”) includes one or more sensitive elements arranged in an orthogonal configuration to provide high-sensitivity directional performance. The one more sensitive elements may be seismometers arranged in a pendulum-type configuration. The AVS further includes a hydrophone.

    Abstract: This disclosure provides peptides which bind to LAG3, such as SAPWEPLHWPEDWWQGTGEW (SEQ ID NO:1), and can be used to block the interaction of LAG 3 with other molecules such as MHC-II, FGL1, and α-synuclein. These peptides can be used for various therapeutic purposes, such as inhibiting the progression of a hyperproliferative disorder, including cancer, or inhibiting the progression of a synucleinopathy, inhibiting the progression of sepsis, inhibiting the progression of an infectious disease, and enhancing a response to a vaccine.
