摘要： Techniques for verifiable computation for cross-domain information sharing are disclosed. An untrusted node in a distributed cross-domain solution (CDS) system is configured to: receive a first data item and a first cryptographic proof associated with the first data item; perform a computation on the first data item including one or more of filtering, sanitizing, or validating the first data item, to obtain a second data item; generate, using a proof-carrying data (PCD) computation, a second cryptographic proof that indicates (a) validity of the first cryptographic proof and (b) integrity of the first computation on the first data item; and transmits the second data item and the second cryptographic proof to a recipient node in the distributed CDS system. Alternatively or additionally, the untrusted node may be configured to transmit a cryptographic proof to a trusted aggregator in the CDS system.

摘要： An acoustic vector sensor and a method of detecting an acoustic vector are described. An object suspended in the fluid medium by a non-contact support structure. The object and the non-contact support structure are configured so that the object moves in response to any disturbance of the fluid by an acoustic wave; The non-contact support structure of the object comprises a plurality of solenoids that each produce a magnetic field in a fluid medium. A measurement measures movement of the object. A processing device determines an acoustic intensity vector of the acoustic wave based on the measured movement of the object.

摘要： Systems and methods for using auditorily-induced vection (AIV) to enhance a person's attitude awareness are provided herein. In at least one embodiment, an auditory object is projected based on the orientation of the person or a vehicle and the projected auditory is provided to the person. By projecting the auditory object, the attitude of the person or the vehicle can be conveyed to the person to enhance the person's attitude awareness.

摘要： A method for classifying images of oligolayer exfoliation attempts. In some embodiments, the method includes forming a micrograph of a surface, and classifying the micrograph into one of a plurality of categories. The categories may include a first category, consisting of micrographs including at least one oligolayer flake, and a second category, consisting of micrographs including no oligolayer flakes, the classifying comprising classifying the micrograph with a neural network.

摘要： A technology is described for optical communication. An example of the technology can include receiving an event stream containing indications of independent events detected by pixels in an event camera. An event may be a change in brightness detected by a pixel in the pixel array, and the pixel independently generates an indication of the event in response to detecting the event. The event stream can be demultiplexed into a plurality of communication streams containing related events associated with a plurality of communication sources. The events contained in a communication stream can be aggregated based in part on an event proximity and an event time that associates an event with other events contained in the event stream. The plurality of communication streams can be demodulated to extract optically transmitted information from the plurality of communication streams, which can be sent to a data consumer.

摘要： The present disclosure is drawn to loop-mediated isothermal amplification (LAMP) reaction assemblies including a substantially hygroscopic agent free LAMP reagent mixture in combination with a solid-phase reaction medium. The present disclosure also includes systems for a chromatic LAMP analysis including a substantially non-reactive solid phase reaction medium, and a non-interfering reagent mixture. The present disclosure also includes solid phase LAMP reaction mediums comprising a substrate, an adhesive layer disposed on the substrate, a reaction layer disposed on the adhesive layer, and a spreading layer disposed on the reaction layer. The present disclosure also includes methods of testing for a presence of a target nucleotide sequence including providing a biological sample, and dispensing the sample into a test environment having a solid phase reaction medium in combination with a LAMP reagent mixture and a pH sensitive dye.
