Protective immunity against Mycobacterium tuberculosis (Mtb) requires IFNG. Besides, IFNG-mediated induction of autophagy suppresses survival of virulent Mtb in macrophage cell lines. We investigatedâ€¦ (More)

By generalizing the idea of extended triangle of a graph, we succeed in obtaining a common framework for the result of Roberts and Spencer about clique graphs and the one of Szwarc4ter about Hellyâ€¦ (More)

We present a linear time algorithm to greedily orient the edges of a path graph model to obtain a directed path graph model (when possible). Moreover we extend this algorithm to find an odd sun whenâ€¦ (More)

A Banach space E has the Grothendieck property if every (linear bounded) operator from E into c 0 is weakly compact. It is proved that, for an integer k > 1, every k-homogeneous polynomial from Eâ€¦ (More)

Chordal graphs and their clique graphs (called dually chordal graphs) possess characteristic tree representations, namely, the clique tree and the compatible tree, respectively. The following problemâ€¦ (More)

A complete set of a graph G is a subset of vertices inducing a complete subgraph. A clique is a maximal complete set. Denote by C(G) the clique family of G. The clique graph of G, denoted by K(G), isâ€¦ (More)

A path graph is the intersection graph of paths in a tree. An open problem mentioned in the literature is to describe a characterization of path graphs by forbidden induced subgraphs. In this paper,â€¦ (More)
