On wavenumber spectra for sound within subsonic jets
, 2014 This paper clarifies the nature of sound spectra within subsonic jets. Three problems, of increasing complexity, are presented. Firstly, a point source is placed in a two-dimensional plug flow and the sound field is obtained analytically.

Propagation thermoelastic impulse through a cylindrical waveguide under sidewall heat interchanging
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2011 The paper is devoted to a study of coupled harmonic thermoelastic impulse guided propagation through an infinite circular cylinder. Heat interchanging is supposed to take place between sidewall of the waveguide and environment.

Spin-Spin Correlation Enhanced by Impurities in a Frustrated Two-leg Spin Ladder
, 2013 We theoretically study a spin-spin correlation enhanced by non-magnetic impurities in a frustrated two-leg spin ladder. The frustration is introduced by the next-nearest-neighbor antiferromagnetic interaction in the leg direction in the antiferromagnetic

New Regime of MHD Turbulence: Cascade Below Viscous Cutoff
, 2002 In astrophysical situations, e.g. in the interstellar medium (ISM), neutrals can provide viscous damping on scales much larger than the magnetic diffusion scale.

, 2016 The spatial-wavenumber filtering technique of Lamb wave is gradually applied for damage inspection of composite structure in recent years because it is an effective approach to distinguish the wave propagating direction and mode.

, 2014 We provide a simple but robust bound on the primordial curvature perturbation in the range $10^4 {\rm Mpc}^{-1} < k < 10^5 {\rm Mpc}^{-1}$, which has not been constrained so far unlike low wavenumber modes.

Instability of a thin conducting foil accelerated by a finite wavelength intense laser
New Journal of Physics, 2015 We derive a theoretical model for the Rayleigh–Taylor (RT)‐like instability for a thin foil accelerated by an intense laser, taking into account finite-wavelength effects in the laser wave field. These finite-wavelength effects lead to the diffraction of

Radial cancellation in spinning sound fields [PDF]
, 2010 The radiating part of a circular acoustic source is determined on the basis of an exact analysis of the radiation properties of a source with angular dependence $\exp \J n\theta$ and arbitrary radial dependence.

Enhancement of Kinematic Accelerations by Wavenumber Correlation Filtering
Sensors, 2016 To obtain kinematic accelerations with high accuracy and reliability, multiple Global Positioning System (GPS) receivers with a single antenna can be used for airborne gravimetry.

Grain boundary dynamics in stripe phases of non potential systems
, 2006 We describe numerical solutions of two non potential models of pattern formation in nonequilibrium systems to address the motion and decay of grain boundaries separating domains of stripe configurations of different orientations.
