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...

We present a partial-wave analysis of the polarization data for the reaction ~ p~ p → ppπ◦, based solely on the recent measurements at IUCF for this channel. The fit leads to a χ2 per degree of freedom of 1.7. Methods for an improved analysis are discussed. We compare the extracted values to those from a meson exchange model.

Reflection and transmission of plane waves between two initially stressed thermoelastic half-spaces with orthotropic type of anisotropy is studied. Incidence of a SV-type wave from the lower half-space is considered and the amplitude ratios of the reflected and transmitted SV-wave, P-wave and thermal wave are obtained by using appropriate boundary conditions. Numerical computation for a particu...

INTRODUCTION P wave axis is one of the most practical clinical tool for evaluation of cardiovascular disease. The aim of our study was to evaluate the P wave axis in electrocardiogram (ECG), left atrial function and association between the disease activity score in patients with systemic lupus erythematosus (SLE). METHODS Standard 12-lead surface ECGs were recorded by at a paper speed of 25 m...

BACKGROUND Circumferential pulmonary vein isolation (CPVI) is a widely used treatment for paroxysmal atrial fibrillation (AF). Several P wave duration (PWD) parameters have been suggested to predict post-ablation recurrence, but their use remains controversial. This study aimed to identify novel P wave indices that predict post-ablation AF recurrence. MATERIAL AND METHODS We selected 171 consec...
