Given a graph G = (V; E) and k positive integers n1; n2; : : : ; nk such that ∑k i=1 ni = |V |, we wish to 2nd a partition P1; P2; : : : ; Pk of the vertex set V such that |Pi| = ni and Pi induces a connected subgraph of G for all i; 16 i6 k. Such a partition is called a k-partition of G. A graph G with n vertices is said to be k-partitionable if there exists a k-partition of G for any partitio...

It has been shown that the E7 protein of the high-risk HPV-16 transforms cells in vitro and binds pRB, p107 and p130, so called pocket proteins associated in cells with DREAM proteins, while that of the low-risk HPV-6 does not transform cells and binds p130 but not pRB or p107. These facts may indicate that p130 is essential for the HPV life cycle. To gain further insight into the relationship ...
