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
Baptism for the dead something that Marcion denied, and that, in fact, "baptized for the dead" means baptized for the body destined to die and rise again. Somewhat similarly, John Chrysostom explained Paul's mention of people being "baptized for the dead" as a reference to the profession of faith they made in their own future resurrection before being baptized. Some interpret "baptized for the dead" as a metaphor for martyrdom, as in and baptism is a metaphor for suffering or martyrdom; accordingly they would translate it as "being baptized with a view to death". In this interpretation, the phrase is closely linked with what
