Abstract Spiral waves in the neocortex may provide a spatial framework to organize cortical oscillations, thus help signal communication. However, noise influences spiral wave. Many previous theoretical studies about mainly focus on unbounded Gaussian noise, which contradicts that real physical quantity is always bounded. Furthermore, non-Gaussian also important for dynamical behaviors of excitable media. Nevertheless, there are no results concerning effect bounded wave till now. Based...
In this work, we demonstrate a new chaotic signal-induced phenomenon that the output of signal-driven bistable system can be consistently mapped to specific logic gate operation in an optimal window signal intensity. We term logical resonance (LCR). Then, intuitive interpretation for LCR is given based on potential well map and mean first-passage time. Through mechanism, with proper intensity used obtain reliable system. Besides, appropriately increasing effectively improve response speed...
It was demonstrated recently that logical chaotic resonance (LCR) can be observed in a bistable system. In other words, the system operate robustly as specific logic gate an optimal window of signal intensity. Here, we report size intensity remarkably extended by exploiting constructive interaction and periodic force, well coupling, coupled addition, medium-frequency force increasing also lead to improvement response speed devices. The results are corroborated circuit experiments. Taken...
Neurons can detect weak target signals from complex background through stochastic resonance (SR) and vibrational (VR) mechanisms. However, random phase variation of rapidly fluctuating is generally ignored in classical VR or SR studies. Here, the are modeled by bounded noise with derived Wiener process. Then, influences on signal detection discussed FitzHugh–Nagumo (FHN) neuron. Numerical results reveal occurrence noise‐induced single‐ biresonance as well a transition between them....
A set-reset latch is a basic building block of computers and can be used to store state information. Here, by testing the influence two logical input signals on reliable logic operation in bistable system, we found that there are types signals, namely, suprathreshold subthreshold signals. For achieved without any driving forces exhibits certain anti-interference ability; for single harmonic could induce correct but with narrow optimal parameter region. The introduction biharmonic-induced...
Coupling-induced logical stochastic resonance (LSR) can be observed in a noise-driven coupled bistable system where the behaviors of interpreted consistently as specific logic gate an appropriate noise level. Here constant coupling is extended to time-varying coupling, and then we investigate effect on LSR periodically driven system. When intensity oscillates with same frequency periodic force or relatively high frequency, successfully yields desired output. irregularly phase disturbance,...
We study coherence resonance (CR) in the FitzHugh–Nagumo (FHN) neurons under cross-correlated sine-Wiener (CCSW) noises. It is numerically demonstrated that reciprocal coefficient of variance inter-spike intervals (R) increases with increasing amplitude or correlation time CCSW noises, reaches maximum at proper time, and then decreases, suggesting appearance CR phenomenon. In addition, occurrence sensitive to a parameter range amplitudes times Thus, can be controlled by regulating noises FHN...
Coherent feed-forward loops exist extensively in realistic biological regulatory systems, and are common signaling motifs. Here, we study the characteristics propagation mechanism of output noise a coherent transcriptional loop that can be divided into main road branch. Using linear approximation, derive analytical formulae for total full loop, branch, road, which verified by Gillespie algorithm. Importantly, find (i) compared with branch motif or motif, effectively attenuate level; (ii)...
During early vertebrate development, various small non-coding RNAs (sRNAs) such as MicroRNAs (miRNAs) and Piwi-interacting (piRNAs) are dynamically expressed for orchestrating the maternal-to-zygotic transition (MZT). Systematic analysis of expression profiles zebrafish RNAome will be greatly helpful understanding sRNA regulation during embryonic development.We first determined sRNAs eight distinct stages development by sRNA-seq technology. Integrative analyses with a new computational...

It was demonstrated recently that there are optimal windows of noise intensity or frequency and amplitude the periodic driving force, which let a bistable system operate reliably as logic gates. These phenomena called logical stochastic resonance (LSR). Given force is not always perfect regular, may be phase disturbance in force; therefore, Wiener process used here to model then effects on reliability agility gates explored detail. Comparing with aperiodic appropriate can drive yield similar...
