Pseudoelastic pure P-mode wave equation

K - P - P equation at the critical wave speed : continuing

Recently Harris (1999), using probabilistic arguments alone, has given new proofs of the (known) existence, asymptotics and uniqueness of travelling wave solutions to the K-P-P equation. This paper is a sequel to Kyprianou (2000b) which provides alternative probabilistic arguments for supercritical wave speeds. We complete our probabilis-tic analysis here for the more diicult case of critical w...

Inappropriate mode switch consecutive to P-wave double counting.

We report a case of multiple inappropriate mode switches in a patient with a dual-chamber pacemaker, resulting from P-wave double counting due to a double potential on the atrial electrogram. The differential diagnosis of this rarely reported phenomenon is discussed.

Asymptotic Behavior of Solution for p-Laplacian Type Wave Equation

Pseudoelastic nature of pterygium.

Elastotic degeneration in cases of pterygium, as in pinguecula, is characterized by the appearance of vermiform, coiled, and knotty fibres which take up elastic stain, but these so-called elastic fibres appear to differ from natural elastic tissue. There are certain skin diseases in which an apparent increase in elastic fibres is seen (Tunbridge, Tattersall, Hall, Astbury, and Reed, I952). Gill...

Wave-equation prestack depth migration for sub-basalt P and converted wave imaging

We apply 2-D wave-equation prestack depth migration to a North Sea basalt dataset. High velocity and impedance contrasts across a basalt layer causes low P-wave reflection signal-to-noise ratio under the basalt. We first migrate the P-wave data with a provided depth velocity model, and then replace sub-basalt P-wave velocity with a simple estimate of shear wave velocity and migrate locally-conv...
