Chimera patterns induced by distance-dependent power-law coupling in ecological networks
This paper reports the occurrence of several chimera patterns and the associated
transitions among them in a network of coupled oscillators, which are connected by a long-range …

Spatial coexistence of synchronized oscillation and death: A chimeralike state
PS Dutta, T Banerjee - Physical Review E, 2015 - APS
We report an interesting spatiotemporal state, namely the chimeralike incongruous coexistence
of synchronized oscillation and stable steady state (CSOD) in a network of nonlocally …

Stochasticity and bistability in insect outbreak dynamics
There is a long history in ecology of using mathematical models to identify deterministic
processes that may lead to dramatic population dynamic patterns like boom-and-bust outbreaks. …

Robustness of early warning signals for catastrophic and non‐catastrophic transitions
Early warning signals (EWS) are statistical indicators that a rapid regime shift may be forthcoming.
Their development has given ecologists hope of predicting rapid regime shifts before …

Searching for optimal coalition structures
S Sen, PS Dutta - Proceedings Fourth International Conference …, 2000 - ieeexplore.ieee.org
Coalition formation has been a very active area of research in multiagent systems. Most of
this research has concentrated on decentralized procedures that allow self-interested agents …

[HTML][HTML] Early warning signals for critical transitions in a thermoacoustic system
Dynamical systems can undergo critical transitions where the system suddenly shifts from
one stable state to another at a critical threshold called the tipping point. The decrease in …

EWSmethods: an R package to forecast tipping points at the community level using early warning signals, resilience measures, and machine learning models
Early warning signals (EWSs) represent a potentially universal tool for identifying whether a
system is approaching a tipping point, and have been applied in fields including ecology, …

[HTML][HTML] Anticipating the novel coronavirus disease (COVID-19) pandemic
The COVID-19 outbreak was first declared an international public health, and it was later

Anticipating critical transitions in epithelial–hybrid-mesenchymal cell-fate determination
In the vicinity of a tipping point, critical transitions occur when small changes in an input
condition cause sudden, large, and often irreversible changes in the state of a system. Many …
