Frequency locking and travelling burst sequences in community structured network of inhibitory neurons with differing time-scales
Kunal Mozumdar, G. Ambika
We report the emergent dynamics of a community structured modular network of chaotic Hindmarsh-Rose (HR) neurons with inhibitory synapses. We find the inhibitory coupling between t…
Degree weighted recurrence networks for the analysis of time series data
Rinku Jacob, K. P. Harikrishnan, R. Misra +1
Recurrence networks are powerful tools used effectively in the nonlinear analysis of time series data. The analysis in this context is done mostly with unweighted and undirected co…
Dynamics of slow and fast systems on complex networks
Kajari Gupta, G. Ambika
We study the occurrence of frequency synchronised states with tunable emergent frequencies in a network of connected systems. This is achieved by the interplay between time scales…
Mechanisms for tuning clustering and degree-correlations in directed networks
G. Kashyap, G. Ambika
With complex networks emerging as an effective tool to tackle multidisciplinary problems, models of network generation have gained an importance of their own. These models allow us…
Nonlinearity in Data with Gaps: Application to Ecological and Meteorological Datasets
Sandip V. George, G. Ambika
Datagaps are ubiquitous in real world observational data. Quantifying nonlinearity in data having gaps can be challenging. Reported research points out that interpolation can affec…
Detecting abnormality in heart dynamics from multifractal analysis of ECG signals
Snehal M. Shekatkar, Yamini Kotriwar, K. P. Harikrishnan +1
The characterization of heart dynamics with a view to distinguish abnormal from normal behavior is an interesting topic in clinical sciences. Here we present an analysis of the Ele…
