Abstract: Meltable flame retardant compositions and fibers fabricated thereof are provided. Compositions of the present disclosure comprise a polymer, a nitrogenous compounds and/or a phosphorus compound. Fibers and compositions of the present disclosure can be used to make fabrics. When fibers, fabrics, and compositions of the present disclosure are exposed to flame, non-flammable gases are released such that the flames is retarded and/or extinguished.

Abstract: Embodiments disclosed herein describe computing private set intersection (PSI) between various parties using delegation to other devices and in one round of interaction (request and response). The various parties involved and their associated computing devices are referred to herein as participants. The protocol is forward-secure and completely hides the data of participants from an eavesdropper. Because the protocol only uses a single round of interaction, it is more efficient and does not require each participant to have servers that remain online continuously.

Abstract: Disclosed herein are system, method, and computer program product embodiments for issuing assets and/or asset tokens using zero-knowledge proofs (“ZKPs”). An issuance system may receive a command to issue an asset. The issuance system may determine that issuing the assets would not violate administrator-defined or network-defined rules that may govern the types of assets and/or the quantity of assets that the issuance system may issue. The issuance system may then issue the assets and generate a ZKP corresponding to the issuance and indicating adherence to the rules while concealing information related to the asset token, such as the types of assets and/or quantity of assets. The issuance system may publish the ZKP to a blockchain so that verifier nodes may confirm that the issuance system adhered to the rules while still preventing access to the underlying issuance information.

Abstract: Embodiments disclosed herein describe computing calculations based on two overlapping private sets between various parties. To conduct the calculation, an intersection of the overlapping private sets data lists is conducted without revealing the underlying data. A homomorphic encryption is conducted on the intersecting data elements to allow them to be compared.

Abstract: Compositions and articles with improved flame properties and fabric with improved melt dripping properties is disclosed. Reduced melt dripping can prevent injuries. Methods for making and using such compositions, articles and fabric are disclosed.

Abstract: Compositions of injection molded articles, multilayer extruded articles, and 3D printed articles with improved flame properties and with improved melt dripping properties are disclosed. Improved flame resistant articles may be beneficial for a large number of injection molded parts, 3D printed parts, and extruded parts. Reduced melt dripping also may be beneficial for such applications. Methods for using such compositions, printed parts, molded parts, and extruded parts are disclosed.

Abstract: Disclosed herein are system, method, and computer program product embodiments for performing transactions or atomic swaps using zero-knowledge proofs (“ZKPs”). A first system may propose a transaction between with a second system. The first system may generate a first ZKP indicating that the first system has possession of an asset desired by the second system and that the first system is committing the asset to the transaction. The second system may also similarly generate a second ZKP. These ZKPs may be encrypted and exchanged. The second system may receive an encrypted version of the first ZKP, perform a decryption using a key specific to the second system, and verify the ZKP. When the parties verify the ZKPs, this confirms that each party has committed the requested asset and that the transaction may proceed. The transaction may be committed to a blockchain.

Abstract: Disclosed herein are system, method, and computer program product embodiments for generating and chaining zero-knowledge proofs (“ZKPs”) using proof chaining. A proof may be divided into different components to analyze data in a series and/or parallel manner using chained proof systems. The proof systems may generate hash values indicating that particular functions were applied to the instances of the underlying data. The hash values may prove that a particular function was applied to instances of the underlying data. Using the proof chaining configuration, a data supply system may generate a ZKP allowing a data requesting system to trust a function result without needing to receive the underlying data.

Abstract: In order to provide interventional access during an image-guided interventional procedure, while increasing the signal-to-noise ratio for generated images compared to a single loop coil, a local coil includes a single coil element disposed around an opening through the local coil and two coil elements positioned on opposite sides of the single coil element. The opening provides access for an interventional tool used during the image-guided interventional procedure.

Abstract: A method and a system for generating private randomness and/or public randomness are provided. A measurement of a public randomness and/or a measurement of a plaintext may be obtained, and a desired size of a private randomness may be determined based on the measurements. The measurements may be based on one or more Tsallis entropy values of the public randomness and/or the plaintext. Private randomness may be generated, the private randomness may be encrypted, the private randomness may be deleted so that the private randomness is unrecoverable, and the encrypted private randomness may be published. Encrypted private randomness and public randomness may be obtained, and a new public randomness may be generated based on the public randomness and the encrypted private randomness.

Abstract: A method to extract information from samples taken at different times from a mammalian. These samples are analyzed with respect to one or more analytes giving one or more responses, creating one or more response curves. From this/these response curves is/are changes in the responses calculated as slope, curvatures or mathematical functions. This is especially useful for early detection of acute myocardial infarction.

Abstract: Example magnetic resonance imaging (MRI) radio frequency (RF) coils are described. An MRI RF coil may include a first terminal and a second terminal that are connected by a coaxial cable. Rather than rely exclusively on two terminal passive components (e.g., resistor, inductor, capacitor), example coax MRI RF coils rely on the capacitance that can be created in the coax cable between the inner conductor and the outer conductor. The capacitance of the coil may be controlled by selectively disrupting (e.g., cutting, stripping) the outer conductor, the inner conductor, or the dielectric material disposed between the inner and outer conductor.

Abstract: An instrument for measuring aspheric optical surfaces includes both an optical wavefront sensor and a single-point optical profilometer. The optical wavefront sensor measures surface height variations throughout one or more areas of an aspheric test surface. The single-point profilometer measures surface height variations along one or more traces on the aspheric test surface. At least one of the traces intersects at least one of the areas, and respective spatial frames of reference for the traces and areas are relatively adapted to each other by minimizing differences between points of nominal coincidence between the areas and traces.
