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
Liver: A Fictional Organ with a Surface Anatomy of Four Lobes and controlling metaphor – there’s a tale for each lobe – but is less interested in the organ as a metabolic regulator than in what happens when it’s damaged beyond repair. At this point, Self’s gift for (ahem) bilious satire kicks in, its target largely the ‘slapstick of addiction’ – for which the reformed junky has witheringly little time...Self has all the fun you’d expect with this, and the result is satire so vicious it makes Charlie Brooker look restrained."
