Now by Hurwitz's Root Theorem all zeros of [[DELTA].sub.[epsilon]](z) in this domain including the complex conjugate will be in [[union].sup.n(k)-1.sub.j=1] [O.sub.j] for [epsilon] sufficiently small and by number equal to the number of the real zeros of [C.sub.[sigma]](z) - f(z) in [k[pi]/[sigma], (k + 1)[pi]/[sigma]], counting multiplicities.
If M is a matrix, we denote by [M.sup.T] the transpose of M, by [bar.M] the complex conjugate of M, by [M.sup.*] the transpose complex conjugate of M, and by [M.sup.-1] the inverse of M.
Lead appeared to target a type of cell known as antigen presenting cells, and its effect was based on specific peptide-major histocompatibility complex conjugate. The results suggest that lead may pose even more long-term health threats than originally thought.
More generally, if the FFT of one time-domain signal Q is multiplied by the complex conjugate of the FFT of another signal R, a cross power spectrum results.
