Chimera states in a multi-weighted neuronal network
Iqtadar, Hussain; Jafari, Sajad; Perc, Matjaž; Ghosh, Dibakar ( Elsevier , 2022 , Article)There are multiple types of interactions among neurons, each of which has a remarkable effect on the neurons' behavior. Due to the significance of chimeras in neural processes, in this paper, we study the impact of different ... -
Hidden and Self-Excited Collective Dynamics of a New Multistable Hyper-Jerk System with Unique Equilibrium
Vijayakumar, M. D.; Natiq, Hayder; Leutcho, Gervais Dolvis; Rajagopal, Karthikeyan; Jafari, Sajad; Hussain, Iqtadar... more authors ... less authors (2022 , Article)Nonlinear dynamical systems with hidden attractors belong to a recent and hot area of research. Such systems can exist in different forms, such as without equilibrium or with a stable equilibrium point. This paper focuses ... -
A Novel Highly Nonlinear Quadratic System: Impulsive Stabilization, Complexity Analysis, and Circuit Designing
Ramesh, Arthanari; Bahramian, Alireza; Natiq, Hayder; Rajagopal, Karthikeyan; Jafari, Sajad; Hussain, Iqtadar... more authors ... less authors ( Hindawi , 2022 , Article)This work introduces a three-dimensional, highly nonlinear quadratic oscillator with no linear terms in its equations. Most of the quadratic ordinary differential equations (ODEs) such as Chen, Rossler, and Lorenz have at ... -
Oyster oscillator: a novel mega-stable nonlinear chaotic system
Ramakrishnan, Balamurali; Ahmadi, Atefeh; Nazarimehr, Fahimeh; Natiq, Hayder; Jafari, Sajad; Hussain, Iqtadar... more authors ... less authors ( Springer , 2021 , Article)Designing novel mega-stable chaotic oscillators has been a hot topic of research lately. In the current paper, a two-dimensional mega-stable oscillator is presented. The oscillator has a vast amount of coexisting limit ... -
A simple one-dimensional map-based model of spiking neurons with wide ranges of firing rates and complexities
Alireza, Bahramian; Ramadoss, Janarthanan; Nazarimehr, Fahimeh; Rajagopal, Karthikeyan; Jafari, Sajad; Hussain, Iqtadar... more authors ... less authors ( Elsevier , 2022 , Article)This paper introduces a simple 1-dimensional map-based model of spiking neurons. During the past decades, dynamical models of neurons have been used to investigate the biology of human nervous systems. The models simulate ...
