In science:

Due to the strong fluctuations of space-time at this level, these differentiable functions become afflicted by degenerate singularities of which versal deformations and blowups allow to generate two covering “middle-ground” and “mass” fields of space and time.

Efficient numerical methods for computing ground states and dynamics of dipolar Bose-Einstein condensates
Such a ratio quantity exhibits a general trend of increasing δIAS isospin mixing with Z within same isospin multiplets and as well it reveals enhanced ∆T = 2 decays to the ground state of even-even N = Z nuclei with increasing δIAS towards the middle of the shell.

The analysis also shows that there is a trend of increasing isospin mixing between isobaric analog 0+ states due to a charge dependent J = 0 pairing interaction towards the middle of the shell and for ∆T = 2 decays to the ground state of an even-even N = Z daughter nucleus.
