Fig. 1 Characteristics of stable and unstable runs in PIC simulations.
Figure 1, modified after Figure two of Liu et al. (2014), illustrates the evolution of stable and unstable runs.

Characteristics of stable (left column, c, e, g) and unstable runs (right column, d, f, h). a The initial state and b the corresponding entropy function S x), which are the same for all runs.
Despite the periodic scenes of the unstable governess running around the stately mansion bearing a candle that does little to lighten the gloomy staircase and corridors, the apparitions or ghosts are not particularly spooky; they deliver baleful looks and vanish.

Weld said Trump is unstable, has run a grievance campaign, sees those who look or speak differently than he does as enemies, and has proved himself incapable of handling criticism.
Examples are forepoling and breasting techniques as developed for the hazardous case of running (unstable) ground.
