Abstract: The invention provides efficient searching with fuzzy criteria in very large information systems. The technique of the present invention uses the Pigeonhole Principle approach. This approach can be utilized with different embodiments, but the most effective realization would be to amplify some already given intrinsic approximate matching capabilities, like those in the FuzzyFind method [1][2]. Considering the following problem, data to be searched is presented as a bit-attribute vector. The searching operation includes finding a subset of this bit-attribute vector that is within particular Hamming distance. Normally, this search with approximate matching criteria requires sequential lookup for the whole collection of the attribute vector. This process can be easily parallelized, but in very large information systems this still would be slow and energy consuming.

Abstract: A system and method for producing graphene includes a heating block, substrate, motor and collection device. The substrate is arranged about the heating block and is configured to receive heat from the heating block. A motor is connected to the substrate to rotate the substrate about the heating block. A cathode and anode are configured to direct a flux stream for deposit onto the rotating substrate. A collection device removes the deposited material from the rotating substrate. A heating element is embedded in the heating block and imparts heat to the heating block. The heating block is made of cement or other material that uniformly disperses the heat from the heating element throughout the heating block. The flux stream can be a carbon vapor, with the deposited flux being graphene.
Abstract: The present disclosure relates to composites of hollow carbon nanospheres (HCNS) and a metal, a metalloid, an alloy, a compound thereof, or any combination of the foregoing, and the use of such composites for making ion storage materials, such as negative electrode active material for lithium ion batteries.

Abstract: A CubeSat satellite has a solar cell and an arc propulsion system. The arc propulsion system includes a power source, a first lead coupled to the power source and to a cathode, and a second lead coupled to the power source and to an anode. The solar cell is used as the cathode of the propulsion system.
Abstract: The disclosure teaches antagonists of Hepatitis C Virus (HCV) derived microRNA, which are useful in methods for treating and protecting against HCV-mediated hepatocellular carcinogenesis.
Abstract: The present invention provides optical computing by means of fast Fourier transform Integration on Silicon On Insulator chip technology with implementation in the analog and temporal domain. This is done by cascading (N?2) stages of delayed interferometers (couplers and phase shifters) where a parallel set of N time samples are taken and using the delay lines and phase of the optical components (constructive/deconstructive interference) the DFT is computed. The Optical Fast Fourier Transform (OFFT) design was built on passive components (2×2 couplers: cascaded Mach Zehnder Interferometer) used for addition and subtraction through optical interference, waveguides with short path differences are used for phase shifting and waveguides with long path differences are used for signal delay based on the needed number of outputs. Since the OFFT is a system of imbalanced interferometers, there are additional bends designed to compensate for the difference in power ratios of the arms.
Abstract: Systems and methods for asset monitoring utilize a network, one or more data servers, one or more asset-monitoring modules, and one or more beacon modules to monitor assets deployed across a facility. The systems and methods are asset-agnostic and are able to provide statistical forecasts and degradation model for each asset monitored. The systems and methods may further apply real-time regression, including Bayesian updating techniques to provide real-time corrections to forecasts and degradation models.
Abstract: A handheld system includes a reference pressure source configured to generate a reference pressure. The handheld system also includes a primary pressure source coupled to the reference pressure source. The primary pressure source is configured to generate a primary pressure in a primary pressure range. The primary pressure is less than the reference pressure, and the primary pressure is induced by the reference pressure source. The handheld system also includes a secondary pressure source coupled to the primary pressure source. The secondary pressure source is configured to generate a secondary pressure in a secondary pressure range. The secondary pressure is less than the primary pressure, and the secondary pressure is induced by the primary pressure source.
Abstract: The invention describes methods for producing a biphasic nanocomposite scaffold comprising custom polymer-based core-shelled nanospheres by the physical and chemical attachment of two disparate polymeric materials whose composition can be readily modified with tissue-specific nanomaterials and products created using such methods. The custom nanospheres are constructed via co-axial wet electrospraying and can be employed to deliver compounds to the polymeric materials.
