A new approach which differs from the conventional pattern recognition techniques in partitioning a seal imprint image into a triangular tessellation is proposed. The image plane is segmented into a mesh of triangles according to the Delaunay triangulation paradigm, and the distribution of the triangular area is used as the primary feature for matching unrecognized seal imprints with model imag...

A barrier (seal) must form at the cut ends of a severed axon if a neuron is to survive and eventually regenerate. Following severance of crayfish medial giant axons in physiological saline, vesicles accumulate at the cut end and form a barrier (seal) to ion and dye diffusion. In contrast, squid giant axons do not seal, even though injury-induced vesicles form after axonal transection and accumu...

This study compared intracuff pressure (ICP) during mechanical ventilation in a variety of currently used endotracheal (ET) and tracheostomy (trach) tube cuffs and related cuff physical characteristics. Tracheostomy tube physical characteristics were also measured. Variation was observed to exist between "just-seal" inspiratory and end-expiratory intracuff pressure during mechanical ventilation...

SEAL was rst introduced in 1] by Rogaway and Copper-smith as a fast software-oriented encryption algorithm. It is a pseu-dorandom function which stretches a short index into a much longer pseudorandom string under control of a secret key pre-processed into internal tables. In this paper we rst describe an attack of a simpliied version of SEAL, which provides large parts of the secret tables fro...
