Bistable nerve conduction [PDF]
Biophysical Journal, 2022 AbstractThe essence of the nerve system is to transmit information from and to different parts of the body in response to environmental changes. Here we show that a bistable conduction behavior can occur in the nerve system, which exhibits stimulus-dependent fast and slow conduction waves.

Bubbling and bistability in two parameter discrete systems [PDF]
, 1978 We present a graphical analysis of the mechanisms underlying the occurrences of bubbling sequences and bistability regions in the bifurcation scenario of a special class of one dimensional two parameter maps.

Chemical Communications, 2009 A switchable donor-acceptor pretzelane composed of a crown ether containing tetrathiafulvalene and 1,5-dihydroxynaphthalene recognition units and a covalently tethered cyclobis(paraquat-p-phenylene) ring exhibits unidirectional motion on both oxidation (forwards) and reduction (backwards).

Bistability phenomena in one-dimensional polariton wires [PDF]
, 2013 We investigate the phenomena of bistability and domain wall propagation in polaritonic systems with dissipation provided by the interaction with incoherent phonon bath.

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

Physical Review Letters, 2000 We extend elasticity theory of filaments to encompass systems, such as bacterial flagella, that display competition between two helical structures of opposite chirality. A general, fully intrinsic formulation of the dynamics of bend and twist degrees of freedom is developed using the natural frame of space curves, spanning from the inviscid limit to ...

Coherent control of intersubband optical bistability in quantum wells [PDF]
, 2003 We present a study of the nonlinear intersubband (ISB) response of conduction electrons in a GaAs/AlGaAs quantum well to strong THz radiation, using a density-matrix approach combined with time-dependent density-functional theory. We demonstrate coherent

Molecular 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 effect in the extreme strong coupling regime of the Jaynes-Cummings model [PDF]
, 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.

Bistability through Triadic Closure [PDF]
Internet 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 ...
