Abstract: Method and system for predicting labels for nodes in an observed graph, including deriving a plurality of random graph realizations of the observed graph; learning a predictive function using the random graph realizations; predicting label probabilities for nodes of the random graph realizations using the learned predictive function; and averaging the predicted label probabilities to predict labels for the nodes of the observed graph.

Abstract: Method and system for detecting potentially perturbed nodes in a graph that comprises potentially perturbed nodes and clean nodes, comprising: calculating, for each of a plurality of nodes of the graph, a discrepancy value in respect of the node, wherein the discrepancy value for each node indicates a statistical discrepancy for classification probabilities associated with the node and classification probabilities associated with neighbouring nodes; fitting a statistical distribution for the discrepancy values for the clean nodes; determining a detection threshold for potentially perturbed nodes based on the statistical distribution; and identifying nodes having a discrepancy value greater than the detection threshold as potentially perturbed nodes.

Abstract: A method for reducing levels of JAK 1 and thereby blocking the signal transduction pathways that are employed by IFN-.alpha., IFN-.beta., and IFN-.gamma. is provided. In one embodiment the method comprises the steps of: providing a cytomegalovirus (CMV) gene product selected from the group consisting of the CMV immediate early gene (IE) products, the CMV early gene (E) products, and combinations thereof; and introducing the CMV gene product or products into cells at levels sufficient to decrease the levels of JAK 1 in the cell. In another embodiment the method comprises the steps of providing a DNA molecule that comprises a CMV IE gene, a CMV E gene, or combinations thereof; introducing the DNA molecule into the cell; and inducing the expression of CMV IE and E genes in the cell, wherein the expression of products encoded by the CMV IE and CMV E genes decreases the levels of JAK 1 in the cell.
