Abstract The phase velocity is discussed using de Broglie relations and Schrödinger equation. We argue that in non-relativistic quantum mechanics the Hamiltonian should be added by a rest-energy term ...

New statistical method is proposed to coherently combine Baryon Acoustic Oscillation statistics (BAO) and peculiar velocity measurements exploiting decomposed density-density and velocity-velocity ...

We use a simple model in which the fluctuations of velocity and temperature of the liquid phase are approximated by periodic oscillations. The amplitude of the oscillations is inhomogeneous in space.

Plasma extraction transit time (PETT) oscillation belongs to the negative resistance oscillation, whose features vary greatly with operation conditions. Besides, these oscillation features determine ...

Conventional Doppler methods for blood velocity estimation only estimate the velocity component along the ultrasound (US) beam direction. This implies that a Doppler angle under examination close to ...

The oscillations of the vortex domain wall velocity are consequences of the interplay between the rotating driving field and the periodically changing domain wall spin structure.
