Tune shift with amplitude of the system. When the tune reaches resonant values, it can be unstable, and thus a tune-shift with amplitude can limit the stability region, or dynamic aperture. In classical mechanics, a simple example of a system with tune shift with amplitude is a pendulum. In accelerator physics, both the transverse and the longitudinal dynamics show tune shift with amplitude. A simple model of the transverse dynamics is of an oscillator with a single sextupole, it is referred to as the Hénon map. Another model for this case is the Standard Map. An important example is the typical case of distributed
Some Girls Are Bigger Than Others track in then out again, and took the reverb back off when reintroducing the song: "A bit like opening a door, closing it, then opening it again and walking in". The lyric paraphrases Johnny Tillotson's 1962 single "Send Me the Pillow That You Dream On", and broadly references the 1964 comedy "Carry On Cleo" ("Oooh, I say"). In the mainstream British music press, "Some Girls Are Bigger Than Others" was mentioned in the context of "The Queen Is Dead". In the "NME", Adrian Thrills wrote, "As an album with humour never far from its surface, it is fitting that "The
