We investigate theoretically the enhancement of mechanical squeezing in a multimode optomechanical system by introducing a coherent phonon–photon interaction via the backward stimulated Brillouin scattering(BSBS)proc...
The deep geological repository for radioactive waste in Switzerland will be embedded in an approximately 100 m thick layer of Opalinus Clay.The emplacement drifts for high-level waste(approximately 3.5 m diameter)are ...

Tamping squeeze is essential for maintaining ballasted tracks.Previous studies have simulated squeezing behavior as a linear motion with a constant squeezing distance,which is unsuitable for various ballast beds in th...
This study introduces the representation of natural number sets as row vectors and pretends to offer a new perspective on the strong Goldbach conjecture. The natural numbers are restructured and expanded with the incl...
