Numerical Studies of Optical Bistability of Absorptive Type
, 2011 Theoretical analysis is presented to search for the purely absorptive optical bistability in a Fabry-Perot cavity filled with a saturable absorber. A simple model of singlet absorption is used on numerically solving the relationships between the input ...

Detection of biological switches using the method of Gröebner bases
BMC Bioinformatics, 2019 Background Bistability and ability to switch between two stable states is the hallmark of cellular responses. Cellular signaling pathways often contain bistable switches that regulate the transmission of the extracellular information to the nucleus where

Bistability: requirements on cell-volume, protein diffusion, and thermodynamics. [PDF]
PLoS ONE, 2015 Bistability is considered wide-spread among bacteria and eukaryotic cells, useful, e.g., for enzyme induction, bet hedging, and epigenetic switching. However, this phenomenon has mostly been described with deterministic dynamic or well-mixed stochastic ...

Hysteresis and resettable bistability.
, 2018 Solid (dashed) lines indicate stable (unstable) equilibria for fixed values of input, Off = Low Equilibrium, B = Bistability, and On = High Equilibrium. Resettable bistability: When input signal is withdrawn from a bistable system, and the system resets ...

Origami‐Inspired Structural Design for Aquatic‐Terrestrial Amphibious Robots
Advanced Robotics Research, EarlyView.This work presents a lightweight amphibious origami robot actuated by a single shape memory alloy wire. A rigid foldable origami structure with displacement amplification enables efficient terrestrial crawling and aquatic swimming. The addition of fan‐shaped units allows controllable turning in both environments.

A Soft Robotic Fish With a Dielectric Elastomer Actuator Body and Negative Stiffness Spine
Advanced Robotics Research, EarlyView.This work introduces a bio‐mimetic soft robotic fish driven by fiber‐reinforced dielectric elastomer actuators integrated as its body. By prestretching this active skin against a flexible spine, a negative stiffness system is created, enabling large‐amplitude bending.
