Brain natriuretic peptide and P wave duration in dialysis patients

, 2007
Objectives P wave duration and dispersion, defined as the difference between the maximum and minimum P duration, are regarded as very important non-invasive ECG markers for assessing atrial arrhythmia risk. Plasma brain natriuretic peptide (BNP) level is

The Role of P‐Wave Variables in Enhancing Prediction of New‐Onset Atrial Fibrillation in Patients With Acute Myocardial Infarction

Annals of Noninvasive Electrocardiology
Background After acute myocardial infarction (AMI), it is common to observe new‐onset atrial fibrillation (NOAF), which is often related to a negative prognosis. Some P‐wave variables (P‐wave duration [PWD], P‐wave amplitude, and interatrial block [IAB]),

A Simplified Laminar Flow Model for the Pultrusion of Glass Fiber/Polyethylene Terephthalate Commingled Yarns

Advanced Engineering Materials, EarlyView.
A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

Electrochemical Behavior of Flame‐Sprayed Sc‐Doped AlCoCrFeMo High‐Entropy Alloy Coatings in 3.5% Sodium Chloride Solution

Advanced Engineering Materials, EarlyView.
Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.
