Nasal and oral inspiration during natural speech breathing.
PURPOSE The purpose of this study was to determine the typical pattern for inspiration during speech breathing in healthy adults, as well as the factors that might influence it. METHOD Ten healthy adults, 18–45 years of age, performed a variety of speaking tasks while nasal ram pressure, audio, and video recordings were obtained. Inspirations were categorized as nasal-only, oral-only, simulta...
متن کاملFinitely forcible graphons
We investigate families of graphs and graphons (graph limits) that are determined by a finite number of prescribed subgraph densities. Our main focus is the case when the family contains only one element, i.e., a unique structure is forced by finitely many subgraph densities. Generalizing results of Turán, Erdős–Simonovits and Chung–Graham–Wilson, we construct numerous finitely forcible graphon...
متن کاملFinitely forcible graphons and permutons
We investigate when limits of graphs (graphons) and permutations (permutons) are uniquely determined by finitely many densities of their substructures, i.e., when they are finitely forcible. Every permuton can be associated with a graphon through the notion of permutation graphs. We find permutons that are finitely forcible but the associated graphons are not. We also show that all permutons th...
متن کاملElectromyographic analysis of trapezius and sternocleidomastoideus muscles during nasal and oral inspiration in nasal- and mouth-breathing children.
The purpose of this study was to evaluate sternocleidomastoideus (SCM) and trapezius (superior fibers) muscle activity patterns in mouth-breathing children, and to compare them with nasal-breathing children. Forty-six children, of both sexes, ranging from 8 to 12 years old, were evaluated through electromyography. The selected children were divided into two groups; Group I, was made up of 26 mo...
متن کاملInfinite dimensional finitely forcible graphon
Graphons are analytic objects associated with convergent sequences of dense graphs. Problems from extremal combinatorics and theoretical computer science led to a study of finitely forcible graphons, i.e., graphons determined by finitely many subgraph densities. Lovász and Szegedy conjectured that the topological space of typical vertices of such a graphon always has finite dimension, which wou...
