Fast Community Detection Based on Distance Dynamics
Tsinghua Science and Technology, 2017 The distance dynamics model is excellent tool for uncovering the community structure of a complex network. However, one issue that must be addressed by this model is its very long computation time in large-scale networks.

On the Connectedness of Attractors for Dynamical Systems
Journal of Differential Equations, 1997 The paper addresses the question of when the global attractor of a continuous semigroup of operators acting on a connected metric space is connected (assuming that the global attractor exists). The two main results are that the attractor is connected if the semigroup is actually a semiflow, or for arbitrary semigroups, if the space is also locally ...

ON A DYNAMICAL SYSTEM WITH MULTIPLE CHAOTIC ATTRACTORS [PDF]
International Journal of Bifurcation and Chaos, 2007 The chaotic behavior of the Rabinovich–Fabrikant system, a model with multiple topologically different chaotic attractors, is analyzed. Because of the complexity of this system, analytical and numerical studies of the system are very difficult tasks.

Place Cells, Grid Cells, Attractors, and Remapping
Neural Plasticity, 2011 Place and grid cells are thought to use a mixture of external sensory information and internal attractor dynamics to organize their activity. Attractor dynamics may explain both why neurons react coherently following sufficiently large changes to the ...

Hippocampal Attractor Dynamics Predict Memory-Based Decision Making. [PDF]
Curr Biol, 2016 Contains fulltext : 163311.pdf (Publisher’s version ) (Closed access)Memories are thought to be retrieved by attractor dynamics if a given input is sufficiently similar to a stored attractor state [1–5].

Influence of aggregation on benthic coral reef spatio-temporal dynamics [PDF]
Royal Society Open Science, 2019 Spatial patterning of coral reef sessile benthic organisms can constrain competitive and demographic rates, with implications for dynamics over a range of time scales. However, techniques for quantifying and analysing reefscape behaviour, particularly at

Detecting alternative attractors in ecosystem dynamics [PDF]
Communications Biology, 2021 AbstractDynamical systems theory suggests that ecosystems may exhibit alternative dynamical attractors. Such alternative attractors, as for example equilibria and cycles, have been found in the dynamics of experimental systems. Yet, for natural systems, where multiple biotic and abiotic factors simultaneously affect population dynamics, it is more ...

Entropy Increase in Switching Systems
Entropy, 2013 The relation between the complexity of a time-switched dynamics and the complexity of its control sequence depends critically on the concept of a non-autonomous pullback attractor.

An attractor-based complexity measurement for Boolean recurrent neural networks. [PDF]
PLoS ONE, 2014 We provide a novel refined attractor-based complexity measurement for Boolean recurrent neural networks that represents an assessment of their computational power in terms of the significance of their attractor dynamics.

Dominant Attractor in Coupled Non-Identical Chaotic Systems
Entropy, 2022 The dynamical interplay of coupled non-identical chaotic oscillators gives rise to diverse scenarios. The incoherent dynamics of these oscillators lead to the structural impairment of attractors in phase space.
