Evaluation from the quality of life in the oral breathers patients

International Archives of Otorhinolaryngology, 2012
Introduction: The oral breathing is a frequent symptom in childhood and has many alterations that compromise the child physical and cognitive development, negatively influencing from the oral breather, comparing her with the not oral breathers.

Dark breathers in granular crystals

Physical Review E, 2013
We present a study of the existence, stability and bifurcation structure of families of dark breathers in a one-dimensional uniform chain of spherical beads under static load. A defocus- ing nonlinear Schrodinger equation (NLS) is derived for frequencies that are close to the edge of the phonon band and is used to construct targeted initial conditions ...

On the Fractional Dynamics of Kinks in Sine-Gordon Models

Mathematics
In the present work, we explored the dynamics of single kinks, kink–anti-kink pairs and bound states in the prototypical fractional Klein–Gordon example of the sine-Gordon equation.

Breather Propagation and Arrest in Significantly Nonlinear Chains

Applied Sciences
In the current paper, we study breather propagation and arrest in chains with significantly nonlinear interactions of elements depending on the type of nonlinearity. We extend the consideration of the two-stage propagation of breathers in these chains on

Phase reduction analysis of traveling breathers in reaction-diffusion systems

Physical Review Research
We formulate a theory for phase reduction analysis of traveling breathers in reaction-diffusion systems with spatial translational symmetry. In this formulation, the spatial and temporal phases represent the position and oscillation of a traveling ...
