Analysis of noise-induced bistability in Michaelis Menten single-step enzymatic cycle
noise-induced bistability Michaelis Menten single-step enzymatic cycle
2011/8/11
Abstract: In this paper we study noise-induced bistability in a specific circuit with many biological implications, namely a single-step enzymatic cycle described by Michaelis Menten equations with qu...
Noise induced state transitions, intermittency and universality in the noisy Kuramoto-Sivashinksy equation
Noise induced state transitions intermittency universality noisy Kuramoto-Sivashinksy equation
2010/11/18
We analyze the effect of pure additive noise on the long-time dynamics of the noisy Kuramoto-
Sivashinsky (KS) equation in a regime close to the instability onset. We show that when the noise is high...
Linear noise approximation of noise-induced oscillation in NF-κB signaling network
Linear noise approximation noise-induced oscillation NF-κB signaling network
2010/11/15
NF-{\kappa}B, one of key regulators of inflammation, apoptosis, and differentiation, was found to have noisy oscillatory shuttling between the nucleus and the cytoplasm in single cells when cells are...
Noise-induced oscillatory shuttling of NF-κB in a two compartment IKK-NF-κB-IκB-A20 signaling model
Noise-induced oscillatory shuttling NF-κB two compartment IKK-NF-κB-IκB-A20 signaling model
2010/11/15
NF-{\kappa}B is a pleiotropic protein whose nucleo-cytoplasmic trafficking is tightly regulated by multiple negative feedback loops embedded in the NF-{\kappa}B signaling network and contributes to di...
Noise-Induced Dynamic Symmetry Breaking and Stochastic Transitions in ABA Molecules: I. Classification of Vibrational Modes
Noise-Induced Dynamic Symmetry Breaking Stochastic Transitions in ABA Molecules Classification of Vibrational Modes
2014/9/24
The dissipative vibrational dynamics of a symmetric triatomic ABA molecule is extensively studied in a series of three papers. The momentum-dependent rotor model is used to describe the dynamical beha...
Effective phase dynamics of noise-induced oscillations in excitable systems

2010/4/1
We develop an effective description of noise-induced oscillations based on deterministic phase dynamics. The phase equation is constructed to exhibit correct frequency and distribution density of nois...
Noise-induced dynamic symmetry breaking and stochastic transitions in ABA molecules: II. Symmetric–antisymmetric normal mode switching
Dynamic symmetry breaking Stochastic transitions Symmetric-to-antisymmetric normal mode switching Environment induced dephasing Triatomic ABA molecules
2014/9/24
The second paper of the series discusses the effect of thermal noise on the stretching vibrational dynamics of symmetric triatomic ABA molecules. In particular, noise-induced transitions between symme...
The DO-climate events are probably noise induced: statistical investigation of the claimed 1470 years cycle
DO-climate event statistical investigation 1470 years cycle
2008/11/4
The significance of the apparent 1470 years cycle in the recurrence of the Dansgaard-Oeschger (DO) events, observed in the Greenland ice cores, is debated. Here we present statistical significance tes...
Noise-Induced Transitions in a Simplified Model of the Thermohaline Circulation
Noise-Induced Transitions Simplified Model Thermohaline Circulation
2008/7/2
A simplified box ocean model for the North Atlantic is used to study the influence of multiplicative short-term climate variability on the stability and long-term dynamics of the North Atlantic thermo...
