Electrocardiogram of Clinically Healthy Mithun (Bos frontalis): Variation among Strains [PDF]
Veterinary Medicine International, 2010 A study was conducted to establish the normal electrocardiogram in four different genetic strains of mithun (Bos frontalis). Electrocardiography, cardiac electrical axis, heart rate, rectal temperature and respiration rate were recorded in a total of 32 ...

Parallel QR Factorization of Block Low-Rank Matrices [PDF]
, 2022 We present two new algorithms for Householder QR factorization of Block Low-Rank (BLR) matrices: one that performs block-column-wise QR, and another that is based on tiled QR. We show how the block-column-wise algorithm exploits BLR structure to achieve arithmetic complexity of $\mathcal{O}(mn)$, while the tiled BLR-QR exhibits $\mathcal{O}(mn^{1.5 ...

Design of a web laboratory interface for ECG signal analysis using MATLAB builder NE
Open Computer Science, 2022 An electrocardiogram (ECG) is a noninvasive test, determining any defect in the heart rate or rhythm or changes in the shape of the QRS complex is very significant to detect cardiac arrhythmia.

QRS micro-fragmentation as a mortality predictor. [PDF]
, 2022 AIMS Fragmented QRS complex with visible notching on standard 12-lead electrocardiogram (ECG) is understood to represent depolarization abnormalities and to signify risk of cardiac events.

Accurate Fetal QRS-Complex Classification from Abdominal Electrocardiogram Using Deep Learning
International Journal of Computational Intelligence Systems, 2023 Fetal heart monitoring during pregnancy plays a critical role in diagnosing congenital heart disease (CHD). A noninvasive fetal electrocardiogram (fECG) provides additional clinical information for fetal heart monitoring.

Is there a utility for QRS dispersion in clinical practice? [PDF]
, 2017 Prognostic markers derived from standard ECG have always been seductive. Increased dispersion of durations of the P wave, of the QRS complex, or of the QT interval has been associated with the risk of atrial fibrillation, ventricular arrhythmias, sudden ...

Fast Time-Evolution of Matrix-Product States using the QR decomposition [PDF]
, 2022 We propose and benchmark a modified time evolution block decimation (TEBD) algorithm that uses a truncation scheme based on the QR decomposition instead of the singular value decomposition (SVD). The modification reduces the scaling with the dimension of the physical Hilbert space $d$ from $d^3$ down to $d^2$. Moreover, the QR decomposition has a lower

VLSI Implementation of QRS Complex Detector Based on Wavelet Decomposition
IEEE Access, 2022 This paper presents a very large–scale integration chip for a novel discrete wavelet transform (DWT) based QRS complex detection algorithm. In many aspects of electrocardiogram (ECG) analyses, QRS complex detection is the first step.

Effects of capillary number and flow rates on the hydrodynamics of droplet generation in T-junction microfluidic systems [PDF]
Journal of the Taiwan Institute of Chemical Engineers, Volume 129,
December 2021, Pages 64-79, 2021 The hydrodynamics of droplets is significant in wide-ranging applications involving immiscible fluids and emulsions in food and pharmaceutical. The control and manipulation of droplets are primarily a function of flow governing and geometrical parameters.
