The Hadwiger number, chordal graphs and -perfection
AKCE International Journal of Graphs and Combinatorics, 2017 A graph is chordal if every induced cycle has three vertices. The Hadwiger number is the order of the largest complete minor of a graph. We characterize the chordal graphs in terms of the Hadwiger number and we also characterize the families of graphs ...

On an edge partition and root graphs of some classes of line graphs
Electronic Journal of Graph Theory and Applications, 2017 The Gallai and the anti-Gallai graphs of a graph $G$ are complementary pairs of spanning subgraphs of the line graph of $G$. In this paper we find some structural relations between these graph classes by finding a partition of the edge set of the line ...

Advanced Science, EarlyView.This study uses gut microbiome data to predict corticosteroid response in patients with immune thrombocytopenia (ITP). Fecal samples from 212 patients with ITP are sequenced. Six machine‐learning algorithms are used to train predictive models. The support vector machine‐based model integrated clinical data and selected microbial species, diversities ...

Discrete Mathematics, 2003 AbstractAlthough chordal graphs may seem at first to be a poor choice to approach using cycle/cutset graph duality, portions of chordal graph theory can be successfully dualized within the context of nonseparable 3-edge-connected graphs. A simple recognition algorithm for such ‘dual-chordal graphs’ involves the further restriction to 3-connected ...

Chordal embeddings of planar graphs
Discrete Mathematics, 2003 AbstractRobertson and Seymour conjectured that the treewidth of a planar graph and the treewidth of its geometric dual differ by at most one. Lapoire solved the conjecture in the affirmative, using algebraic techniques. We give here a much shorter proof of this result.

Retracts of Products of Chordal Graphs [PDF]
Journal of Graph Theory, 2012 Inthisarticle,wecharacterizethegraphsG thataretheretracts of Cartesian products of chordal graphs. We show that they are exactly the weakly modular graphs that do not contain K2,3, the 4-wheel minus one spoke W − 4 , and the k-wheels Wk (for k ≥ 4) as induced subgraphs.

Advanced Science, EarlyView.The study reveals that glutaminolysis in macrophages is inhibited under type 2 diabetes mellitus (T2DM) conditions, which impedes fracture healing by reducing bone morphogenetic protein 2 (BMP2) production through increased cytosine methylation on the promoter.

On the cover ideals of chordal graphs [PDF]
TURKISH JOURNAL OF MATHEMATICS, 2019 The independence complex of a chordal graph is known to be shellable due to a result of Van Tuyl and Villarreal. This is equivalent to the fact that cover ideal of a chordal graph has linear quotients. We use this result to obtain recursive formulas for the Betti numbers of cover ideals of chordal graphs. Also, we give a new proof of their result which

Advanced Science, EarlyView.Chronic social stress elevates oxytocin levels, leading to immunosuppression by enhancing regulatory T‐cell activity and promoting anti‐inflammatory macrophage polarization in the spleen. Blocking oxytocin signaling reverses these effects but worsens stress‐induced behavioral disorders and reduces survival rates. This highlights oxytocin's dual role in
