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.

Hidden Multistability in a Memristor-Based Cellular Neural Network
Advances in Mathematical Physics, 2020 In this paper, we report a novel memristor-based cellular neural network (CNN) without equilibrium points. Dynamical behaviors of the memristor-based CNN are investigated by simulation analysis.

Polarization Multistability of Cavity Polaritons [PDF]
Physical Review Letters, 2007 New effects of polarization multistability and polarization hysteresis in a coherently driven polariton condensate in a semiconductor microcavity are predicted and theoretically analyzed. The multistability arises due to polarization-dependent polariton-polariton interactions and can be revealed in polarization resolved photoluminescence experiments ...

The phenomenon of multistability as the electrophysiological phenomenon of myocardium
RUDN Journal of Medicine, 2008 The hypothesis about presence phenomenon of multistability of myocardium which is present on cellular and systemics level is put forward. Multistability is understood as coexistence of two or several various steady periodic rhythms in system with the ...

Cooperative growth in microbial communities is a driver of multistability
Nature CommunicationsMicrobial communities often exhibit more than one possible stable composition for the same set of external conditions. In the human microbiome, these persistent changes in species composition and abundance are associated with health and disease states ...

Multistability and skyrmion annihilation mechanisms in nanodots near ordering temperature
Communications PhysicsMagnetic skyrmions are promising candidates for next-generation information carriers. In confined geometries, they often coexist with other (meta)stable magnetic states under identical conditions, enabling skyrmion-based multi-bit storage applications ...

From Folding Mechanics to Robotic Function: A Unified Modeling Framework for Compliant Origami. [PDF]
Adv Sci (Weinh)A geometry‐consistent DDG framework captures compliant origami deformation from rigid‐like folding to soft panel bending. By tuning crease and panel stiffness, bistable snap‐through responses transform into smooth monostable deformation, enabling programmable stability and robot‐scale locomotion.
