Assortative mixing by degree makes a network more unstable
Markus Brede, Sitabhra Sinha
We investigate the role of degree correlation among nodes on the stability of complex networks, by studying spectral properties of randomly weighted matrices constructed from direc…
Emergence of two-phase behavior in markets through interaction and learning in agents with bounded rationality
Sitabhra Sinha, S. Raghavendra
Phenomena which involves collective choice of many agents who are interacting with each other and choosing one of several alternatives, based on the limited information available t…
Controlling spatiotemporal chaos in excitable media by local biphasic stimulation
Johannes Breuer, Sitabhra Sinha
Controlling spatiotemporal chaos in excitable media by applying low-amplitude perturbations {\em locally} is of immediate applicability, e.g., in treating ventricular fibrillation,…
Terminating ventricular tachycardia by pacing induced dynamical inhomogeneities in the reentry circuit
Sitabhra Sinha, Johannes Breuer
Formation of feedback loops of excitation waves (reentrant circuit) around non-conducting ventricular scar tissue is a common cause of lethal cardiac arrhythmias, such as ventricul…
Spatiotemporal dynamics of pacing in models of anatomical reentry
Sitabhra Sinha, David J. Christini
Reentry around non-conducting ventricular scar tissue, which often causes lethal arrhythmias, is typically treated by rapid stimulation from an implantable defibrillator. However,…
Spiral Turbulence: From the Oxidation of CO on Pt(110) to Ventricular Fibrillation
Ashwin Pande, Sitabhra Sinha, Rahul Pandit
We give a brief overview of systems that show spiral patterns and spatiotemporally chaotic states. We concentrate on two physical systems: (1) the oxidation of CO on Pt(110) and (2…
