Let M(m; n) be the complexity of checking whether a graph G with m edges and n vertices is a median graph. We show that the complexity of checking whether G is triangle-free is at most M(m; m). Conversely, we prove that the complexity of checking whether a given graph is a median graph is at most O(m log n)+T(m log n; n), where T(m; n) is the complexity of nding all triangles of the graph. This...
متن کامل[Emery-Dreifuss muscular dystrophy].
Emery-Dreifuss muscular dystrophy (EDMD) is an inherited muscular disorder characterized by the triad of progressive weakness in humero-peroneal muscles, early onset contractures and cardiomyopathy with conduction block that shows a high risk of sudden death. In 1994, the gene responsible for X-linked EDMD has been identified to Xq28 (designated as STA), that encodes a serine-rich protein of 25...
متن کاملFrustrated Blume-Emery-Griffiths model
A generalised integer S Ising spin glass model is analysed using the replica formalism. The bilinear couplings are assumed to have a Gaussian distribution with ferromagnetic mean < Jij >= J0. Incorporation of a quadrupolar interaction term and a chemical potential leads to a richer phase diagram with transitions of first and second order. The first order transition may be interpreted as a phase...
متن کامل[Emery-Dreifuss muscular dystrophy: case report].
Emery-Dreifuss muscular dystrophy type 1 (EDMD1) is a familial disease with X-Linked recessive transmission, caused by a mutation in a nuclear envelope protein, emerin. Clinical manifestations usually occur in adolescence and include contractures, muscle atrophy and weakness, and cardiac conduction disturbances. We describe the case of a young male, aged 16, with first-degree atrioventricular (...
متن کاملEigenvalue Comparison on Bakry-emery Manifolds
It is called shrinking, steady, or expanding soliton if a > 0, a = 0 or a < 0 respectively. More generally (M, g, f) is called a Bakry-Emery manifold if the so-called Bakry-Emery Ricci tensor Rcij + fij ≥ agij for some a ∈ R. In this paper we apply the modulus of continuity estimates developed in [AC,AC2,AC3] to give a different proof of an eigenvalue comparison estimate on Bakry-Emery manifold...
