Sound amplification by stimulated emission of radiation of a coherent amplification of THz sound. The THz stimulated phonon induced transitions between the electron superlattice states lead to this coherent amplification while processing a population inversion. An essential step towards coherent generation ("sasing") of THz sound and other active hypersound devices has been provided by this achievement of THz sound amplification. Generally, in a device where the threshold for "sasing" is achieved, the technique described by this proposed scheme could be used to measure the coherence time of the emitted hypersound. Sound amplification by stimulated emission of radiation Sound amplification by stimulated emission of radiation (SASER) refers to
A Tale of a Tub in the reception of Swift's work is that the narrator of the work is an extremist in every direction. Consequently, he can no more construct a sound allegory than he can finish his digressions without losing control (eventually confessing that he is insane). For a Church of England reader, the allegory of the brothers provides small comfort. Martin has a corrupted faith, one full of holes and still with ornaments on it. His only virtue is that he avoids the excesses of his brothers, but the original faith is lost to him. Readers of the "Tale" have picked up on
