Epigenetic feedback reshapes dynamical landscapes in gene regulatory networks
Sascha H. Hauck, Sandip Saha, Narsis A. Kiani +1
Understanding how gene regulatory networks (GRNs) give rise to stable and dynamic cellular states remains a central challenge in theoretical biology, particularly when slow epigene…
Complex dynamics and route to quasiperiodic synchronization in non-isochronous directed Stuart-Landau triads
Ankan Pandey, Sandip Saha, Dibakar Ghosh
The coupled Stuart-Landau equation serves as a fundamental model for exploring synchronization and emergent behavior in complex dynamical systems. However, understanding its dynami…
Controlling complex rhythms: A hierarchical approach to limit cycle switching
Sandip Saha, Suvam Pal, Dibakar Ghosh
Limit cycles are self-sustained, closed trajectories in phase space representing (un)-stable, periodic behavior in nonlinear dynamical systems. They underpin diverse natural phenom…
Power Law Behavior of Center-Like Decaying Oscillation : Exponent through Perturbation Theory and Optimization
Sandip Saha
In dynamical systems theory, there is a lack of a straightforward rule to distinguish exact center solutions from decaying center-like solutions, as both require the damping force…
