Switching dynamics of spatial solitary wave pixels [PDF]

, 1993
Separatrices and scaling laws in the switching dynamics of spatial solitary wave pixels are investigated. We show that the dynamics in the full model are similar to those in the plane-wave limit.

The Mid-Pleistocene Transition induced by delayed feedback and bistability [PDF]

, 2018
The Mid-Pleistocene Transition, the shift from 41 kyr to 100 kyr glacial-interglacial cycles that occurred roughly 1 Myr ago, is often considered as a change in internal climate dynamics.

High intermodulation gain in a micromechanical Duffing resonator

, 2005
In this work we use a micromechanical resonator to experimentally study small signal amplification near the onset of Duffing bistability. The device consists of a PdAu beam serving as a micromechanical resonator excited by an adjacent gate electrode.

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

, 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

Emergent Bistability : Effects of Additive and Multiplicative Noise

, 2012
Positive feedback and cooperativity in the regulation of gene expression are generally considered to be necessary for obtaining bistable expression states.

Zenithal bistability in a nematic liquid crystal device with a monostable surface condition [PDF]

, 2003
The ground-state director configurations in a grating-aligned, zenithally bistable nematic device are calculated in two dimensions using a Q tensor approach.

Bistability patterns and nonlinear switching with very high contrast ratio in a 1550 nm quantum dash semiconductor laser [PDF]

, 2012
We report on the experimental observation of optical bistability (OB) and nonlinear switching (NS) in a nanostructure laser; specifically a 1550 nm quantum dash Fabry-Perot laser subject to external optical injection and operated in reflection. Different

Bistable Mechanisms 3D Printing for Mechanically Programmable Vibration Control

Advanced Engineering Materials, EarlyView.
This work introduces a 3D‐printed bistable mechanism integrated into tuned mass dampers (TMDs) for mechanically adaptive passive vibration suppression. Through optimized geometry, the bistable design provides adaptable vibration reduction across a broad range of scenarios, achieving effective vibration mitigation without complex controls or external ...

Dynamical effects induced by long range activation in a nonequilibrium reaction-diffusion system

, 2002
We both show experimentally and numerically that the time scales separation introduced by long range activation can induce oscillations and excitability in nonequilibrium reaction-diffusion systems that would otherwise only exhibit bistability.

Dragging Bistable Fronts

Physica Scripta, 2004
Summary: We consider the dragging of fronts in reaction--diffusion systems with bistable nonlinearity by an external drive, which may be parametric or direct. A perturbation theory is developed for the speed correction of the dragged front. The predictions are found to be in good agreement with direct simulations, apart from an initial transient. While
