In this paper, we consider sampling and reconstruction of signals in a reproducing kernel subspace of L(R), 1 ≤ p ≤ ∞, associated with an idempotent integral operator whose kernel has certain off-diagonal decay and regularity. The space of p-integrable non-uniform splines and the shift-invariant spaces generated by finitely many localized functions are our model examples of such reproducing ker...

there are many studies about epidural fibrosis after surgical manipulation of the spine. we have studied formation of the post laminectomy epidural fibrosis after application of two materials (silicone and teflon) in this report. this expriment is on two groups of rats. two separated laminectomies were done in each rat, one serving as control while in the other laminectomy spaces silicone was u...

A method to visualize polytopes in a four dimensional euclidian space (x, y, z, w) is proposed. A polytope is sliced by multiple hyperplanes that are parallel each other and separated by uniform intervals. Since the hyperplanes are perpendicular to the w axis, the resulting multiple slices appear in the three-dimensional (x, y, z) space and they are shown by the standard computer graphics. The ...
