Abstract: Described is a system for transferring learned knowledge from an electro-optical (EO) domain to a synthetic-aperture-radar (SAR) domain. The system uses a measured similarity between the EO domain and the SAR domain to train a model for classifying SAR images using knowledge previously learned from the electro-optical (EO) domain. Using the trained model, a SAR image is processed to determine regions of interest in the SAR image. A region of interest is classified to determine whether the region of interest corresponds to an object of interest, and classified regions of interest that contain the object of interest are output. The object of interest is displayed on a visualization map, and the visualization map is automatically updated to reflect a change in position of the object of interest.

Abstract: A method and apparatus for converting electromagnetic surface waves from TE mode to TM mode or from TM mode to TE mode. The apparatus includes a dielectric surface having an anisotropic impedance tensor which is preferably obtained by a plurality of electrically conductive unit cells disposed on the dielectric surface and arranged in a two dimensional array of unit cells, a majority of the unit cells in said array being divided into at least two portions, with at least one gap separating the at least two portions from each other into two or more patches or plates, the array of unit cells having a surface wave input end and a surface wave output end, gaps in the unit cells disposed closest to the surface wave input end having a first orientation and gaps in said unit cells disposed closest to the surface wave output end having a second orientation different than said first orientation. The electromagnetic surface waves have a frequency greater than a TE cutoff frequency determined by a second solution of Maxwell's equations for said dielectric surface.

Abstract: A method for generating human-machine hybrid predictions of answers to forecasting problems includes: parsing text of an individual forecasting problem to identify keywords; generating machine models based on the keywords; scraping data sources based on the keywords to collect scraped data relevant to the individual forecasting problem; providing the scraped data to the machine models; receiving machine predictions of answers to the individual forecasting problem from the machine models based on the scraped data; providing, by the computer system via a user interface, the scraped data to human participants; receiving, by the computer system via the user interface, human predictions of answers to the individual forecasting problem from the human participants; aggregating the machine predictions with the human predictions to generate aggregated predictions; and generating and outputting a hybrid prediction based on the aggregated predictions.

Abstract: Described is a system for verifiable secret sharing amongst a plurality of servers, including a dealer server and one or more recipient servers. In operation, the dealer server encrypts a secret s using a polynomial and a hash tree with points on the polynomial as leaves. The dealer broadcasts to recipient servers hash tree data, root of the hash tree, and shares of the secret. Through an evaluation process the recipient servers are verified such that upon verification, the recipient servers reconstruct the secret s.

Abstract: Described is a system for memory improvement intervention. Based on both real-time EEG data and a neural model, the system simulates replay of a person's specific memory during a sleep state. Using the neural model, a prediction of behavioral performance of the replay of the specific memory is generated. If the prediction is below a first threshold, then using a memory enhancement intervention system, the system applies an intervention during the sleep state to improve consolidation of the specific memory. If the prediction is below a second threshold, the system reduces the intervention performed using the memory enhancement intervention system.

Abstract: A four-terminal GaN transistor and methods of manufacture, the transistor having source and drain regions and preferably two T-shaped gate electrodes, wherein a stem of one of the two T-shaped gate electrodes is more closely located to the source region than it is to a stem of the other one of the two T-shaped gate electrodes and wherein the stem of the other one of the two T-shaped gate electrodes is more closely located to the drain region than it is to the stem of said one of the two T-shaped gate electrodes. The the gate closer to the source region is a T-gate, and the proximity of the two gates is less than 500 nm from each other. The spacing between the stem of the RF gate and source region and the stem of the DC gate and drain region are preferably defined by self-aligned fabrication techniques. The four-terminal GaN transistor is capable of operation in the W-band (75 to 100 GHz).

Abstract: In a method for emulation of neuromorphic hardware on a computer processor, the neuromorphic hardware including computing circuits, the computing circuits including neurons and synapses connecting the neurons, the neurons being configured to communicate to each other through the synapses via spikes, the computing circuits being configured to execute in parallel in increments of time, the method includes, for each said time increment, emulating processing of the synapses, emulating processing of the neurons, and recording by the processor the next ones of the spikes for a subset of the neurons on a non-transitory physical medium. The processing of the synapses includes receiving previous ones of the spikes at presynaptic ends of the synapses, and transmitting the received previous ones of the spikes to postsynaptic ends of the synapses. The processing of the neurons includes receiving current ones of the spikes and generating next ones of the spikes.

Abstract: Described is a system for geocoding social networks by minimizing total variation. A set of social media data from a social media platform having users is received. A social network is generated from the set of social media data based on communication between users. A ground truth set of locations is determined for users who make their locations public, and the ground truth set of locations is propagated across the social network to generate a location estimate for each user. A confidence measure for each location estimate is then generated.

Abstract: Some variations provide a segmented copolymer composition comprising: fluoropolymer first soft segments that are (α,ω)-hydroxyl-terminated and/or (α,ω)-amine-terminated; polyester or polyether second soft segments that are (α,ω)-hydroxyl-terminated and/or (α,ω)-amine-terminated; isocyanate species possessing an isocyanate functionality of 2 or greater; and polyol or polyamine chain extenders or crosslinkers, wherein the molar ratio of the second soft segments to the first soft segments is less than 2.0. Exemplary segmented copolymers are disclosed. The segmented copolymer composition may be present in a low-friction, low-adhesion coating. Such a coating may be characterized by a coefficient of friction, measured at 90% relative humidity, less than 0.7. Such a coating may be characterized by an average kinetic delay of surface ice formation of at least 10 minutes at −10° C. These coatings are useful as bugphobic and icephobic coatings.
