Circuits and Circulant Minors
(Elsevier, 2019)
Circulant contraction minors play a key role for characterizing ideal circular matrices in terms of minimally non ideal structures. In this article we prove necessary and sufficient conditions for a circular matrix A to ...
Time-scale of minor HIV-1 complex circulating recombinant forms from Central and West Africa

The minor inequalities in the description of the set covering polyhedron of circulant matrices
(Springer Heidelberg, 2014-02)
In this work we give a complete description of the set covering polyhedron of circulant matrices Cskk with = 2, 3 and k ≥ 3 by linear inequalities. In particular, we prove that every non boolean facet defining inequality ...
Generalized minor inequalities for the set covering polyhedron related to circulant matrices
(Elsevier Science, 2016-09)
We study the set covering polyhedron related to circulant matrices. In particular, our goal is to characterize the first Chvátal closure of the usual fractional relaxation. We present a family of valid inequalities that ...

Some advances on the set covering polyhedron of circulant matrices
(Elsevier Science, 2014-03)
Studying the set covering polyhedron of consecutive ones circulant matrices, Argiroffo and Bianchi found a class of facet defining inequalities, induced by a particular family of circulant minors. In this work we extend ...
On the first Chvátal closure of the set covering polyhedron related to circulant matrices
(Elsevier, 2013-11)
We study the set covering polyhedron related to circulant matrices. In particular, our goal is to characterize the first Chvátal closure of the usual fractional relaxation. We present a family of valid inequalities that ...
On dominating set polyhedra of circular interval graphs
(Elsevier Science, 2021-04)
Clique-node and closed neighborhood matrices of circular interval graphs are circular matrices. The stable set polytope and the dominating set polytope on these graphs are therefore closely related to the set packing ...
Differential expression of Ro/SSA 60 kDa and La/SSB, but not Ro/SSA 52 kDa, mRNA and protein in minor salivary glands from patients with primary Sjogren's syndrome
(J Rheumatol Publ Co, 2007-06-01)
Objective. To analyze the protein and messenger RNA (mRNA) expression of La/SSB, Ro/SSA 60, and Ro/SSA 52 antigens in minor salivary glands (MSG) from patients with primary Sjogren's syndrome (pSS).Methods. La/SSB, Ro/SSA ...
