Ensemble modeling of auditory streaming reveals potential sources of bistability across the perceptual hierarchy.

open access: yesPLoS Computational Biology, 2020
Perceptual bistability-the spontaneous, irregular fluctuation of perception between two interpretations of a stimulus-occurs when observing a large variety of ambiguous stimulus configurations.

Chemical sensitivity to the ratio of the cosmic-ray ionization rates of He and H2 in dense clouds [PDF]

open access: yes, 2006
Aim: To determine whether or not gas-phase chemical models with homogeneous and time-independent physical conditions explain the many observed molecular abundances in astrophysical sources, it is crucial to estimate the uncertainties in the calculated ...

Monomeric bistability and the role of autoloops in gene regulation.

open access: yesPLoS ONE, 2009
Genetic toggle switches are widespread in gene regulatory networks (GRN). Bistability, namely the ability to choose among two different stable states, is an essential feature of switching and memory devices.

Bistability effect in the extreme strong coupling regime of the Jaynes-Cummings model [PDF]

open access: yes, 2015
We study the nonlinear response of a driven cavity QED system in the extreme strong coupling regime where the saturation photon number is below one by many orders of magnitude.

Achieving large thermal hysteresis in an anthracene-based manganese(II) complex via photo-induced electron transfer

open access: yesNature Communications, 2022
Achieving magnetic bistability with large thermal hysteresis is still a challenge in material science. Here, the authors report a Mn(II) chain complex that enables light-induced magnetic bistability with a 177 K thermal hysteresis loop.

Bistability in bacteria [PDF]

open access: yesMolecular Microbiology, 2006
SummaryGene expression in bacteria is traditionally studied from the average behaviour of cells in a population, which has led to the assumption that under a particular set of conditions all cells express genes in an approximately uniform manner.

Bistability through Triadic Closure [PDF]

open access: yesInternet Mathematics, 2012
We propose and analyse a class of evolving network models suitable for describing a dynamic topological structure. Applications include telecommunication, on-line social behaviour and information processing in neuroscience. We model the evolving network as a discrete time Markov chain, and study a very general framework where, conditioned on the ...

A computational model of mutual antagonism in the mechano-signaling network of RhoA and nitric oxide

open access: yesBMC Molecular and Cell Biology, 2021
Background RhoA is a master regulator of cytoskeletal contractility, while nitric oxide (NO) is a master regulator of relaxation, e.g., vasodilation. There are multiple forms of cross-talk between the RhoA/ROCK pathway and the eNOS/NO/cGMP pathway, but ...

Nonclassical correlated optical multistability at low photon level for cavity electromagnetically induced transparency

open access: yesNew Journal of Physics, 2022
We study the nonequilibrium dynamic behaviors in a driven-dissipative single-atom cavity electromagnetically induced transparency. The optical bistability and multistability beyond a Kerr nonlinearity are observed utilizing the optical Stark shift ...

The Missing Luminous Blue Variables and the Bistability Jump [PDF]

open access: yes, 2004
We discuss an interesting feature of the distribution of luminous blue variables on the H-R diagram, and we propose a connection with the bistability jump in the winds of early-type supergiants. There appears to be a deficiency of quiescent LBVs on the S
