  It is shown that if a non-zero function $f\in B_\sigma$ has infinitely many
double zeros on the real axis, then there exists at least one pair of
consecutive zeros whose distance apart is greater than
$\dfrac{\pi}{\sigma}\tau^{1/4}$, $\tau\approx5.0625$. A frame algorithm is
provided for reconstructing a function $f\in B_\sigma$ from its nonuniform
samples $\{f^{(j)}(x_i):j=0,1,\dots, k-1, i\in\mathbb{Z}\}$ with maximum gap
condition, $\sup\limits_i(x_{i+1}-x_i)=\delta<\dfrac{1}{\sigma}c_k^{1/2k}$,
where $c_k$ is a Wirtinger-Sobolev constant, using Hermite interpolation.
