Plane-wave diffraction at the periodically corrugated boundary of vacuum and a negative-phase-velocity material
(American Physiological Society, 2004-12)
Considering the diffraction of a plane wave by a periodically corrugated half-space, we show that the transformation of the refracting medium from positive (negative) phase velocity to negative (positive) phase velocity ...
Rapid alignment of velocity and magnetic field in magnetohydrodynamic turbulence
(American Physical Society, 2008-12)
We show that local directional alignment of the velocity and magnetic field fluctuations occurs rapidly in magnetohydrodynamics for a variety of parameters and is seen both in direct numerical simulations and in solar wind ...
Bouncing window for colliding nanoparticles: Role of dislocation generation
(American Physical Society, 2019-03)
Available macroscopic theories—such as the Johnson-Kendall-Roberts (JKR) model—predict sphericalparticles to stick to each other at small collision velocitiesv; above the bouncing velocity,vb, they bounce. Westudy the ...
Threshold wind velocity as an index of soil susceptibility to wind erosion under variable climatic conditions
(John Wiley & Sons Ltd, 2009-12)
Wind erosion starts when the threshold wind velocity (μ t ) is exceeded. We evaluated the sensitivity of μ t to determine the wind erosion susceptibility of soils under variable climatic conditions. Three years field data ...
Reference intervals and percentiles for carotid-femoral pulse wave velocity in a healthy population aged between 9 and 87 years
(Wiley Blackwell Publishing, Inc, 2018-03)
There is little information regarding age-related reference intervals (RIs) of carotidfemoral pulse wave velocity (cfPWV) for large healthy populations in South America. The aims of this study were to determine cfPWV RIs ...
Design and construction of an electromechanical velocity modulator for Mössbauer spectroscopy
(SPRINGER, 2011-11-01)
In this paper we report the design, construction and characterization of an electromechanical velocity modulator for application in Mössbauer spectroscopy. The modulator was constructed with copper coils, Neodymium magnets, ...
