Chimera patterns induced by distance-dependent power-law coupling in ecological networks

T Banerjee, PS Dutta, A Zakharova, E Schöll - Physical Review E, 2016 - APS
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

Y Sharma, KC Abbott, PS Dutta, AK Gupta - Theoretical Ecology, 2015 - Springer
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

PS Dutta, Y Sharma, KC Abbott - Oikos, 2018 - Wiley Online Library
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

EA Gopalakrishnan, Y Sharma, T John, PS Dutta… - Scientific reports, 2016 - nature.com
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

…, S Sidheekh, NC Krishnan, P Sharathi Dutta… - …, 2023 - Wiley Online Library
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] Thermo-elastic interaction without energy dissipation in an infinite solid with distributed periodically varying heat sources

SK Roychoudhuri, PS Dutta - International Journal of Solids and Structures, 2005 - Elsevier
The paper deals with the thermo-elastic interactions due to distributed periodically varying
heat sources in a homogeneous, isotropic, unbounded elastic medium in the context of the …

[HTML][HTML] Anticipating the novel coronavirus disease (COVID-19) pandemic

…, S Chowdhury, SK Sinha, MK Jolly, PS Dutta - Frontiers in public …, 2020 - frontiersin.org
The COVID-19 outbreak was first declared an international public health, and it was later
deemed a pandemic. In most countries, the COVID-19 incidence curve rises sharply over a …

Anticipating critical transitions in epithelial–hybrid-mesenchymal cell-fate determination

…, H Levine, MK Jolly, PS Dutta - Proceedings of the …, 2019 - National Acad Sciences
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 …
