Phase models and clustering in networks of oscillators with delayed coupling [PDF]
, 2016 We consider a general model for a network of oscillators with time delayed, circulant coupling. We use the theory of weakly coupled oscillators to reduce the system of delay differential equations to a phase model where the time delay enters as a phase ...

Abrupt Desynchronization and Extensive Multistability in Globally Coupled Oscillator Simplexes. [PDF]
Physical Review Letters, 2019 Collective behavior in large ensembles of dynamical units with nonpairwise interactions may play an important role in several systems ranging from brain function to social networks. Despite recent work pointing to simplicial structure, i.e., higher-order

Complex Dynamics in a Memcapacitor-Based Circuit
Entropy, 2019 In this paper, a new memcapacitor model and its corresponding circuit emulator are proposed, based on which, a chaotic oscillator is designed and the system dynamic characteristics are investigated, both analytically and experimentally.

Fractional-Order Memristive Wilson Neuron Model: Dynamical Analysis and Synchronization Patterns
Mathematics, 2022 Fractional nonlinear systems have been considered in many fields due to their ability to bring memory-dependent properties into various systems. Therefore, using fractional derivatives to model real-world phenomena, such as neuronal dynamics, is of ...

Multistability and Perceptual Inference [PDF]
Neural Computation, 2012 Ambiguous images present a challenge to the visual system: How can uncertainty about the causes of visual inputs be represented when there are multiple equally plausible causes? A Bayesian ideal observer should represent uncertainty in the form of a posterior probability distribution over causes.

Comprehensive study of phase transitions in relaxational systems with field-dependent coefficients
, 2003 We present a comprehensive study of phase transitions in single-field systems that relax to a non-equilibrium global steady state. The mechanism we focus on is not the so-called Stratonovich drift combined with collective effects, but is instead similar ...

Nature CommunicationsExisting mechanical metamaterials are typically designed to either withstand loads as a stiff structure, shape morph as a floppy mechanism, or trap energy as a multistable matter, distinct behaviours that correspond to three primary classes of ...

Positive multistate protein design [PDF]
Bioinformatics, 2019 AbstractMotivationStructure-based computational protein design (CPD) plays a critical role in advancing the field of protein engineering. Using an all-atom energy function, CPD tries to identify amino acid sequences that fold into a target structure and ultimately perform a desired function.

Emergence, evolution, and control of multistability in a hybrid topological quantum/classical system
, 2017 We present a novel class of nonlinear dynamical systems - a hybrid of relativistic quantum and classical systems, and demonstrate that multistability is ubiquitous.

Riddled Basins of Attraction in Systems Exhibiting Extreme Events [PDF]
, 2017 Using a system of two FitzHugh-Nagumo units, we demonstrate the occurrence of riddled basins of attraction in delay-coupled systems as the coupling between the units is increased.
