Since the introduction of "TCP for congestion control in computer networks", this concept has been widely used in wired networks. TCP congestion control has its different variants in various types of networks. Many other protocols are also introduced, which are derived from "TCP Congestion Control" concept for wired networks. TCP congestion control is(More)
Circulating tumor cells (CTCs) are in limited numbers and heterogeneous, making their detection, isolation, and enumeration a major challenge. To overcome these difficulties, we developed a novel method to detect and enumerate CTCs with invasive property. Our assay consists of three simple steps: enrichment, Matrigel invasion assay, and immunostaining. We(More)

Direct LDA(D-LDA) is a method to solve this problem by firstly whitening the between-class scatter Sb and then diagonalizing the within-class scatter Sw, but the discriminative information in the null space of Sw is always lost indirectly.
