Abstract: A device receives traffic; identifies an address associated with the traffic; determines whether the address is associated with an aggregate interface, the aggregate interface being associated with a first port and a second port. The first port corresponds to a first node in a first state, that indicates that the first node is available to forward the traffic, and the second port corresponds to a second node in a second state, that indicates that that the second node is not available to forward the traffic. The device transmits the traffic to the first node via the first port and to the second node, via the second port, when the address is associated with the aggregate interface. Transmitting the traffic enables the second node to forward the traffic when the first node changes from the first state to the second state.

Abstract: The present invention provides an oligonucleotide composition including a blocker and a first primer oligonucleotide. The blocker oligonucleotide includes a first sequence having a target-neutral subsequence and a blocker variable subsequence. The non-target specific subsequence is flanked on its 3? and 5? ends by the target-neutral subsequence and is continuous with the target-neutral subsequence. The first primer oligonucleotide is sufficient to induce enzymatic extension; herein the first primer oligonucleotide includes a second sequence. The second sequence overlaps with the 5? end of the target-neutral subsequence by at least 5 nucleotides; herein the second sequence includes an overlapping subsequence and a non-overlapping subsequence. The second sequence does not include the non-target specific subsequence.

Abstract: The present disclosure describes the thermodynamic design and concentrations necessary to design probe compositions with desired optimal specificity that enable enrichment, detection, quantitation, purification, imaging, and amplification of rare-allele-bearing species of nucleic acids (prevalence <1%) in a large stoichiometric excess of a dominant-allele-bearing species (wildtype). Being an enzyme-free and homogeneous nucleic acid enrichment composition, this technology is broadly compatible with nearly all nucleic acid-based biotechnology, including plate reader and fluorimeter readout of nucleic acids, microarrays, PCR and other enzymatic amplification reactions, fluorescence barcoding, nanoparticle-based purification and quantitation, and in situ hybridization imaging technologies.

Abstract: Compositions and methods for highly specific nucleic acid probes and primers are provided. The probe system comprises a complement strand and a protector stand that form a partially double-stranded probe. The reaction standard free energy of hybridization between the probe and target nucleic acid as determined by Expression 1 (?G°rxn=?G°t-TC??G°nh-PC+(?G°v-TC??G°h-PC)) is from about ?4 kcal/mol to about +4 kcal/mol. Alternatively, the reaction standard free energy of hybridization between the probe and target nucleic acid is determined by Expression 1 to be within 5 kcal/mol of the standard free energy as determined by Expression 2 (?R? ln(([P]0?[C]0)/[C]0)]), where the [P]0 term of Expression 2 equals the concentration of the protector strand and the [C]0 term of Expression 2 equals the concentration of the complement strand. In addition, a method for on-the-fly fine tuning of a reaction using the present probe is provided.

Abstract: Nucleic acid probes are described comprising a universal component and a target dependent component. The universal component provides an economical advantage in that the universal component can retain any desired functional moiety, such as a fluorophore or other label which can be used with any target dependent component. Thus, the cost of designing target specific functionalized probes is significantly reduced with this probe system by limiting de novo synthesis to only the target dependent component of the probe for each desired target nucleic acid. Furthermore, the probe design of the present disclosure provides high target specificity demonstrating selective binding of the target in a 1% target load sample.

Abstract: An authentication and authorization plug-in model for a cloud computing environment enables cloud customers to retain control over their enterprise information when their applications are deployed in the cloud. The cloud service provider provides a pluggable interface for customer security modules. When a customer deploys an application, the cloud environment administrator allocates a resource group for the customer's application and data. The customer registers its own authentication and authorization security module with the cloud security service, and that security module is then used to control what persons or entities can access information associated with the deployed application. To further balance the rights of the various parties, a third party notary service protects the privacy and the access right of the customer when its application and information are deployed in the cloud.
