Zero sound in a two-dimensional dipolar Fermi gas [PDF]
, 2013 We study zero sound in a weakly interacting 2D gas of single-component fermionic dipoles (polar molecules or atoms with a large magnetic moment) tilted with respect to the plane of their translational motion.

Development of a New Laboratory Technique for Reducing the Peak Particle Velocity Arising from the Blast [PDF]
International Journal of Economic and Environment Geology, 2017 Certain vibrational waves are formed as a result of open quarry blasts. The peak particle velocity occurred by these waves provides that structures and people present around the blast point are negatively affected.
