Park Slope is the first of several neighborhoods to undergo the suspension and alternate-side sign changes.
If the sign of Ψ remains unchanged, the wave function is said to be symmetric with respect to interchange; if the sign changes, the function is antisymmetric.
where is a number of sign changes.
Thus, in view of Rolle's theorem, (G_{r,n,f,a}^{(r)}) has at least n sign changes (and hence exactly n sign changes due to construction).
Hence the function (Delta(t)) has (k-1) sign changes on the interval ([0,a_{k}]).
If however v < 0 in I i then the sign changes.
However, there exist sign changes in ( {s}_z^M-{s}_z^D ) as m is varied.
The phenomenon is explained by group birefringence Bg which decreases and its sign changes as magnetic field increases.
The stress sign changes at a critical oxide thickness, which depends on the circumferential stress at the interface.
Assume that a function x has at least (n+r) sign changes, (x^{(r)}) has not more than n sign changes and (x^{(r)}) is non-zero almost everywhere.
In all of the occurrences, intervals of polarization angle sign changes lasted for several tens of minutes, within which sign changes took place every few minutes (from 2 to 10 min).
