  • Patent number: 9325729
    Abstract: Systems and methods for determining a safety level of a network vulnerable to attack from at least one origin to at least one target are described. Machines, components, and vulnerabilities in a network may be associated to one another. Degrees of similarity among the vulnerabilities may be determined and subsets of vulnerabilities may be grouped based on their determined degrees of similarity to one another. This data may be used to generate an attack graph describing exploitation of vulnerabilities and grouped vulnerabilities and defining vulnerability exploit condition relationships between at least one origin and at least one target. The attack graph may be analyzed using a k-zero day metric function to determine a safety level.

  • Patent number: 9240539
    Abstract: A superconducting nanowire single photon detector (SN-SPD) microelectronic circuit is described which has higher quantum efficiency and signal-to-noise than any SN-SPD's known in the art. The material and configuration of the microelectronic circuit eliminates the polarization dependence and shows improved signal-to-noise over SN-SPD microelectronic circuits known in the art. The higher efficiency, polarization independence, and high signal-to-noise is achieved by vertically stacking two tungsten-silicide (TS) SN-SPDs and electrically connecting them in parallel. This structure forms a multilayer superconducting nanowire avalanche photo-detector (SNAP). A single photon detection device employing the multilayer (SNAP) microelectronic circuit demonstrates a peak system detection efficiency of 87.7% and a polarization dependence of less than 2%. This represents nearly an order of magnitude improvement in both system detection efficiency and reduction of polarization dependence compared to conventional SNSPDs.

  • Patent number: 8962345
    Abstract: A method of characterizing glycans attached to glycoproteins is disclosed herein. The method comprises a first step of immobilizing the glycoproteins on colloidal particles forming glycoprotein/colloidal particles. The glycans on the glycoproteins may then be characterized, for example the composition and/or structure of glycans may be characterized or the glycans attached to proteins may be identified. Characterization may be accomplished by either binding the glycoprotein/colloidal particles with one or more binding agents and assessing the aggregation of the glycoprotein/colloidal particles or by cleaving glycans from the glycoprotein/colloidal particles with a cleaving agent and analyzing the glycans.
