Opinion-Driven Vaccination and Epidemic Dynamics on Heterogeneous Networks
Anika Roy, Ujjwal Shekhar, Subrata Ghosh +2
Vaccination campaigns play a pivotal role in controlling infectious diseases. Their success, however, depends not only on vaccine efficacy and availability but also significantly o…
Mean-Field and Pairwise Approaches for the SIRI Model on Poisson Networks
Akshara Bhat, Abhishek Deshpande, Chittaranjan Hens +1
Compartmental epidemic models, grounded in mass-action kinetics, often assume homogeneous mixing. Although this neglects network structure, recent results show that for Poisson ran…
Teleportation Fidelity of Binary Tree Quantum Repeater Networks
Soumit Roy, Md Rahil Miraj, Chittaranjan Hens +3
Binary tree network, being a subclass of Cayley tree network, is a significant topological structure used for information transfer in a hierarchical sense. In this article, we cons…
Origins of Instability in Dynamical Systems on Undirected Networks
Shraosi Dawn, Subrata Ghosh, Chandrakala Meena +2
Robustness to perturbation is a key topic in the study of complex systems occurring across a wide variety of applications from epidemiology to biochemistry. Here we analyze the eig…
Real-time identification and control of influential pandemic regions using graph signal variation
Sudeepini Darapu, Subrata Ghosh, Dibakar Ghosh +2
The global spread of pandemics is facilitated by the mobility of populations, transforming localized infections into widespread phenomena. To contain it, timely identification of i…
Predicting First-Passage Dynamics in Disordered Systems Exactly: Application to Sparse Networks
Daniel Marris, Chittaranjan Hens, Subrata Ghosh +1
Quantifying how spatial disorder affects the movement of a diffusing particle or agent is fundamental to target search studies. When diffusion occurs on a network, that is on a hig…
