Query: Yukawa Textures, New Physics and Nondecoupling   We point out that New Physics can play an important r\^ ole in rescuing some
of the Yukawa texture zero ans\" atze which would otherwise be eliminated by
the recent, more precise measurements of $V_{CKM}$. As an example, a detailed
analysis of a four texture zero ansatz is presented, showing how the presence
of an isosinglet vector-like quark which mixes with standard quarks, can render
viable this Yukawa texture. The crucial point is the nondecoupling of the
effects of the isosinglet quark, even for arbitrary large values of its mass.
