The aim of edge modification problems is to change the edge set of a given graph as little as possible in order to satisfy a certain property. Edge modification problems in graphs have a lot of… (More)

We present an efficient algorithm for recognizing unit circular-arc (UCA) graphs, based on a characterization theorem for UCA graphs proved by Tucker in the seventies. Given a proper circular-arc… (More)

Many classes of graphs where the vertex coloring problem is polynomially solvable are known, the most prominent being the class of perfect graphs. However, the list-coloring problem is NP-complete… (More)

BACKGROUND
Various mechanisms can contribute to cellular resistance to doxorubicin. These include expression of the multidrug transporter P-glycoprotein (product of the mdr1 gene [also known as… (More)

A b-coloring of a graph is a coloring such that every color class admits a vertex adjacent to at least one vertex receiving each of the colors not assigned to it. The b-chromatic number of a graph G,… (More)

A fluctuation analysis experiment was performed by exposing 15 expanded populations of MES-SA sarcoma cells to paclitaxel (Taxol) at a concentration of 10 nM for 7 days. The mutation rate was… (More)

The clique graph of a graph is the intersection graph of its (maximal) cliques. A graph is self-clique when it is isomorphic with its clique graph, and is clique-Helly when its cliques satisfy the… (More)

A variant of the multidrug-resistant human sarcoma cell line Dx5 was derived by co-selection with doxorubicin and the cyclosporin D analogue PSC 833, a potent inhibitor of the multidrug transporter… (More)
