The frontal sinus dimensions in mouth and nasal breathers in Iraqi adult subjects
Journal of Baghdad College of Dentistry, 2014 Background: The frontal sinus area can be used as a diagnostic aid to recognize mouth breather subjects. The aims of this study were to determine the gender difference in each group, to compare the frontal sinus area between mouth breather and nasal ...

ESR investigation on the Breather mode and the Spinon-Breather dynamical crossover in Cu Benzoate
, 1999 A new elementary-excitation, the so called "breather excitation", is observed directly by millimeter-submillimeter wave electron spin resonance (ESR) in the Heisenberg quantum spin-chain Cu benzoate, in which a field-induced gap is found recently by ...

Advanced Engineering Materials, EarlyView.Carbon nanomaterial‐reinforced epoxy composites exhibit pronounced piezoresistive behavior, enabling intrinsic damage sensing under cyclic and fatigue loading. This review critically compares carbon nanotube and graphene systems, correlating filler content, percolation threshold, and gauge factor with sensing stability and damage evolution.

Dark breather using symmetric Morse, solvent and external potentials for DNA breathing
Eclética Química, 2019 We analyze the dynamics and the quantum thermodynamics of DNA in Symmetric-Peyrard-Bishop-Dauxois model (S-PBD) with solvent and external potentials and describe the transient conformational fluctuations using dark breather and the ground state wave ...

Advanced Functional Materials, EarlyView.The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.

Nucleation of breathers via stochastic resonance in nonlinear lattices [PDF]
, 2009 By applying a staggered driving force in a prototypical discrete model with a quartic nonlinearity, we demonstrate the spontaneous formation and destruction of discrete breathers with a selected frequency due to thermal fluctuations.

Some Exact Solutions to Generalized Kadomtsev-Petviashvili Equation
Advances in Mathematical Physics, 2022 Most of the papers have explored the interactions between solitons with a zero background, while reports about exact solutions for nonzero background are rare.

Directional soliton and breather beams [PDF]
Proceedings of the National Academy of Sciences, 2019 Significance Understanding the fundamental dynamics of directional and localized waves is of significant importance for modeling ocean waves as well as predicting extreme events. We report a theoretical framework, based on the universal (2D + 1) nonlinear Schrödinger equation, that allows the construction of slanted solitons and breathers on ...

Discrete breathers at the interface between a diatomic and monoatomic granular chain [PDF]
, 2010 In the present work, we develop a systematic examination of the existence, stability and dynamical properties of a discrete breather at the interface between a diatomic and a monoatomic granular chain. We remarkably find that such an "interface breather"
