—Edges in social network graphs can model sensitive relationships. In this paper, we consider the problem of edges anonymity in graphs. We propose a probabilistic notion of edge anonymity, called graph confidence, which is general enough to capture the privacy breach made by an adversary who is able to pinpoint target persons in a graph partition based on(More)

HCA587 (also known as MAGE-C2) is a "cancer-testis" antigen highly expressed in a number of malignancies with unique immunological properties, making it a promising target for tumor immunotherapy. In this report, we demonstrated that HCA587 protein, when formulated with adjuvants CpG-containing oligodeoxynucleotides (CpG ODN) and ISCOM, was capable of(More)
