Multiplex Recurrence Networks from multi-lead ECG data
Sneha Kachhara, G. Ambika
We present an integrated approach to analyse the multi-lead ECG data using the frame work of multiplex recurrence networks (MRNs). We explore how their intralayer and interlayer to…
Early Warning Signals Indicate a Critical Transition in Betelgeuse
Sandip V. George, Sneha Kachhara, Ranjeev Misra +1
Critical transitions occur in complex dynamical systems, when the system dynamics undergoes a regime shift. These can often occur with little change in the mean amplitude of system…
Bimodality and Scaling in Recurrence Networks from ECG data
Sneha Kachhara, G. Ambika
Human heart is a complex system that can be studied using its electrical activity recorded as Electrocardiogram (ECG). Any variations or anomalies in the ECG can indicate abnormali…
Higher order spectral analysis of ECG signals
Yamini Kotriwar, Sneha Kachhara, K. P. Harikrishnan +1
Higher Order Spectral (HOS) analysis is often applied effectively to analyze many bio-medical signals to detect nonlinear and non-Gaussian processes. One of the most basic HOS meth…
