We have developed a pseudoelastic wave equation describing pure pressure waves propagating in elastic media. The pressure-mode (P-mode) uses all of the parameters (such as density and P- S-wave velocities). It produces same amplitude variation with offset (AVO) effects PP-reflections computed by conventional equation. Because new is free S-waves, it does not require finer grids for simulation. ...

Background: Psoriasis is a prevalent chronic T cell mediated inflammatory skin disorder. Recent studies have reported an increase in the incidence of arrhythmia in psoriasis patients who run an excessive risk of metabolic syndrome and cardiovascular diseases. P-wave dispersion (PWD) and duration are important electrocardiographic (ECG) markers employed to anticipate the risk of atrial arrhythmi...
