Instability and stability properties of traveling waves for the double dispersion equation [PDF]
, 2002 In this article we are concerned with the instability and stability properties of traveling wave solutions of the double dispersion equation $~u_{tt} -u_{xx}+a u_{xxxx}-bu_{xxtt} = - (|u|^{p-1}u)_{xx}~$ for $~p>1$, $~a\geq b>0$.

Electrocardiographic P-wave Indices as a Useful Tool to Predict Successful Percutaneous Balloon Mitral Valvotomy in Patients with Mitral Stenosis [PDF]
Journal of Cardiovascular and Thoracic Research, 2014 Introduction: Patients with hemodynamically significant mitral stenosis (MS) have prolonged P-wave duration and increased P-wave dispersion (PWD) that decreases after successful percutaneous balloon mitral valvotomy (PBMV).

Cardiac heterogeneity in patients with chronic urticaria; A perusal of P wave and QT dispersions
Medicine Science, 2022 Data on how the heart is affected in Chronic Urticaria (CU), a common annoying chronic dermatological disease, is quite limited. The electrocardiographic parameters; P wave dispersion (PWD) and QT dispersion (QTD) have been consistently reported to be ...

QT dispersion and P wave dispersion in schizophrenia
Psychiatry and Clinical Psychopharmacology, 2019 BACKGROUND: The difference between maximum QT (QTmax) and minimum (QTmin) on electrocardiography (ECG) is known as QT dispersion (QTd). An increase in QTd carries the risk of ventricular arrhythmia and subsequent death.

P wave dispersion and maximum P wave duration are associated with renal outcomes in chronic kidney disease. [PDF]
PLoS ONE, 2014 P wave parameters measured by 12-lead electrocardiogram (ECG) are commonly used as a noninvasive tool to evaluate left atrial enlargement. This study was designed to assess whether P wave parameters were associated with renal outcomes in chronic kidney ...

Radiative pion capture by a nucleon [PDF]
, 2000 The differential cross sections for $\pi^- p \to \gamma n$ and $\pi^+ n \to \gamma p$ are computed up to $O(p^3)$ in heavy baryon chiral perturbation theory (HBChPT). The expressions at $O(p)$ and $O(p^2)$ have no free parameters. There are three unknown

Role of the van Hove Singularity in the Quantum Criticality of the Hubbard Model [PDF]
, 2011 A quantum critical point (QCP), separating the non-Fermi liquid region from the Fermi liquid, exists in the phase diagram of the 2D Hubbard model [Vidhyadhiraja et. al, Phys. Rev. Lett. 102, 206407 (2009)].
