Ground state on the dumbbell graph [PDF]
, 2016 We consider standing waves in the focusing nonlinear Schr\"odinger (NLS) equation on a dumbbell graph (two rings attached to a central line segment subject to the Kirchhoff boundary conditions at the junctions).

Acoustic power measurements of oscillating flames [PDF]
, 1981 The acoustic power of an oscillating flame is measured. A turbulent premixed propane/air flame is situated near a pressure antinode of a standing wave in a laboratory combustion chamber. This standing wave is generated by a piston.

The Periodic Standing-Wave Approximation: Overview and Three Dimensional Scalar Models [PDF]
, 2003 The periodic standing-wave method for binary inspiral computes the exact numerical solution for periodic binary motion with standing gravitational waves, and uses it as an approximation to slow binary inspiral with outgoing waves.

Resonance control of acoustic focusing systems through an environmental reference table and impedance spectroscopy. [PDF]
PLoS ONE, 2018 Acoustic standing waves can precisely focus flowing particles or cells into tightly positioned streams for interrogation or downstream separations. The efficiency of an acoustic standing wave device is dependent upon operating at a resonance frequency ...

Localization of atomic ensembles via superfluorescence [PDF]
, 2006 The sub-wavelength localization of an ensemble of atoms concentrated to a small volume in space is investigated. The localization relies on the interaction of the ensemble with a standing wave laser field.

Primordial standing waves [PDF]
Physical Review D, 2018 We consider the possibility that the primordial fluctuations (scalar and tensor) might have been standing waves at their moment of creation, whether or not they had a quantum origin. We lay down the general conditions for spatial translational invariance, and isolate the pieces of the most general such theory that comply with, or break translational ...

Phase holograms for the three-dimensional patterning of unconstrained microparticles
Scientific Reports, 2023 Acoustic radiation forces can remotely manipulate particles. Forces from a standing wave field align microscale particles along the nodal or anti-nodal locations of the field to form three-dimensional (3D) patterns.

Evaluation of Modulus of Elasticity in Standing Trees and Sawn Wood in Populous deltoids using Nondestructive Stress Wave Testing [PDF]
Iranian Journal of Wood and Paper Industries, 2014 The aim of this paper was to evaluate relationship between dynamic modulus of elasticity (MOEd) in healthy standing trees of Populus deltoides and static modulus of elasticity (MOEs) of sawn lumber from the same standing trees, using nondestructive ...

Excitation of an extreme wave by standing current
Oceanologia, 2023 The statistics suggest that extreme waves cause more damage in shallow waters and at the coast than in the deep sea. In the linear theory of the formation of extreme waves, their existence is interpreted as a local superposition of surface monochromatic ...

The observation of diffraction phases in matter wave scattering
, 2013 We study the diffraction phase of different orders via the Dyson expansion series, for ultracold atomic gases scattered by a standing-wave pulse. As these diffraction phases are not observable in a single pulse scattering process, a temporal Talbot-Lau ...
