AIMS To assess the validity of an online method to quantitatively evaluate cerebral hypometabolism in patients with pharmacoresistant focal epilepsy as a complement to the visual analysis of the 18F-FDG positron emission tomography (PET)/CT exam. METHODS A total of 39 patients with pharmacoresistant epilepsy and probable focal cortical dysplasia [22 patients with frontal lobe epilepsy (FLE) a...
In this paper, we study 3-colorable graphs having no induced 8-vertex path and no induced cycles of specific lengths. We prove a characterization by critical graphs in three particular cases.
Borodin and Kostochka conjectured that every graph G with maximum degree ∆ ≥ 9 satisfies χ ≤ max {ω,∆− 1}. We carry out an in-depth study of minimum counterexamples to the Borodin-Kostochka conjecture. Our main tool is the classification of graph joins A ∗B with |A| ≥ 2, |B| ≥ 2 which are f -choosable, where f(v) := d(v)− 1 for each vertex v. Since such a join cannot be an induced subgraph of a...
