Experimental observation of multistability and dynamic attractors in silicon central pattern generators
Le Zhao, Alain Nogaret

We report on the multistability of chaotic networks of silicon neurons and demonstrate how spatiotemporal sequences of voltage oscillations are selected with timed current stimuli. A three neuron central pattern generator was...

Anisotropic odd viscosity via a time-modulated drive

At equilibrium, the structure and response of ordered phases are typically determined by the spontaneous breaking of spatial symmetries. Out of equilibrium, spatial order itself can become a dynamically emergent concept. In...

Asymmetric excitation of left- and right-tail extreme events probed using a Hawkes model

We construct a two-tailed peaks-over-threshold Hawkes model that captures asymmetric self- and cross-excitation in and between left- and right-tail extreme values within a time series. We demonstrate its applicability by...

Inhibition Delay Increases Neural Network Capacity through Stirling Transform

Inhibitory neural networks are found to encode high volumes of information through delayed inhibition. We show that inhibition delay increases storage capacity through a Stirling transform of the minimum capacity which...

Magnetic Nanoparticles in a Nematic Channel
We study a dilute suspension of magnetic nanoparticles in a nematic-filled channel and how the spatial magnetization M, can be tailored by the nematic anisotropy. We study the spatial configurations as stable critical points of...

Equivalence framework for an age-structured multistage representation of the cell cycle
We develop theoretical equivalences between stochastic and deterministic models for populations of individual cells stratified by age. Specifically, we develop a hierarchical system of equations describing the full dynamics of...

Noise-activated barrier crossing in multi-attractor spiking networks
Noise-activated transitions between coexisting attractors are investigated in a chaotic spiking network. At low noise level, attractor hopping consists of discrete bifurcation events that conserve the memory of initial...

Ratcheting Droplet Pairs

Millimetric droplets may be levitated on the surface of a vibrating fluid bath. Eddi et al. [Europhys. Lett. 82, 44001 (2008)] demonstrated that when a pair of levitating drops of unequal size are placed nearby, they interact...

Local neighbourhoods for first-passage percolation on the configuration model
We consider first-passage percolation on the configuration model. Once the network has been generated each edge is assigned an i.i.d. weight modeling the passage time of a message along this edge. Then independently two vertices...

Logarithmic Vertex Algebras and Non-local Poisson Vertex Algebras

Logarithmic vertex algebras were introduced in our previous paper, motivated by logarithmic conformal field theory (Bakalov and Villarreal in Logarithmic vertex algebras, 2022). Non-local Poisson vertex algebras were...

Mixing time bounds via bottleneck sequences
We provide new upper bounds for mixing times of general finite Markov chains. We use these bounds to show that the total variation mixing time is robust under rough isometry for bounded degree graphs that are roughly isometric...
