«We control the below - threshold harmonic light emission by using electromagnetic fields with time - dependent ellipticity, like we have done to the above - threshold high - order harmonics,» said Chang referring to the creation of a 67 - attosecond pulse of extreme ultraviolet light, which earned him international recognition.
More precisely, ellipticals are sub-classified for ellipticity from E7 (strongly elongated) to E0 (circular), and spirals for prominence of bulge versus spiral arms from Sa (or SABa, SBa) to Sc or Sd.

The process begins when Kepler submits to the ellipticity of the planetary trajectories.
They quantified their shapes according to two measurements: the ellipticity, or length relative to width and the asymmetry, whether one end was pointier and the other rounder.
By examining the eggs of 1,400 species (each species» average egg is represented on this scatterplot by a pale orange dot), researchers found that the shape of bird eggs is determined by two variables: ellipticity and asymmetry.
In many cases the increase of density is obviously attended with a diminution of ellipticity, or a nearer approach to the globular form in the central than in the exterior strata.»
