Fatemeh Safara,Shyamala Doraisamy,Azreen Azman,Azrul Hazri Jantan,Asri Ranga Abdullah Ramaiah +4 more
TL;DR: Multi-level basis selection (MLBS) is proposed to preserve the most informative bases of a wavelet packet decomposition tree through removing less informative bases by applying three exclusion criteria: frequency range, noise frequency, and energy threshold.
Journal ArticleDOI
RenyiBS: Renyi entropy basis selection from wavelet packet decomposition tree for phonocardiogram classification
TL;DR: The promising result of 99.74% accuracy is achieved, confirming the ability of Renyi entropy to select an appropriate basis of the wavelet packet tree and extracting the nonlinear behavior of particular heart sounds.
Journal ArticleDOI
Pregnancy-Associated Spontaneous Coronary Artery Dissection: A Case Report and the Lessons from Practice
TL;DR: In this article , a case of pregnancy-associated spontaneous coronary artery dissection (P-SCAD) was reported in a 26-year-old multigravida woman, who complained of angina postpartum with raised cardiac biomarkers and transient ST-segment elevation on electrocardiograms.
