Cold, season, and incidence of bells palsy
Bell’s palsy is a relatively common disease characterized by the sudden onset of unilateral facial paralysis. Using a centralized system that contains demographic data, the authors estimated rates, trends, and demographic risk of Bell’s palsy during a 2-year period. There were 140 incident cases of Bell’s palsy among patients referring to private clinics (a total of 6500 patients). The crude in...

متن کاملOn incidence coloring for some cubic graphs
In 1993, Brualdi and Massey conjectured that every graph can be incidence colored with ∆+2 colors, where ∆ is the maximum degree of a graph. Although this conjecture was solved in the negative by an example in [1], it might hold for some special classes of graphs. In this paper, we consider graphs with maximum degree ∆ = 3 and show that the conjecture holds for cubic Hamiltonian graphs and some...
متن کاملIncidence Coloring Game and Arboricity of Graphs
An incidence of a graph G is a pair (v, e) where v is a vertex of G and e an edge incident to v. Two incidences (v, e) and (w, f) are adjacent whenever v = w, or e = f , or vw = e or f . The incidence coloring game [S.D. Andres, The incidence game chromatic number, Discrete Appl. Math. 157 (2009), 1980–1987] is a variation of the ordinary coloring game where the two players, Alice and Bob, alte...
متن کاملInterval incidence coloring of subcubic graphs
For a given simple graph G = (V,E), we define an incidence as a pair (v, e), where vertex v ∈ V (G) is one of the ends of edge e ∈ E(G). Let us define a set of incidences I(G) = {(v, e) : v ∈ V (G)∧ e ∈ E(G)∧ v ∈ e}. We say that two incidences (v, e) and (w, f) are adjacent if one of the following holds: (i) v = w, e 6= f , (ii) e = f , v 6= w, (iii) e = {v, w}, f = {w, u} and v 6= u. By an inc...
