Noise is seen as the annoying something for weak signal detection, but noise is beneficial to
enhance weak signals of interest embedded in noise in nonlinear systems. Moreover, the …

The counterintuitive phenomenon that inhibitory autapses enhance coherence resonance
(CR) is investigated in a Hodgkin–Huxley neuronal network, which can be well interpreted …

Hardware-implemented reservoir computing (RC) has been gaining considerable interest in
recent years, in particular for classification and nonlinear-prediction tasks. Such RC systems …

The effect of a coherence resonance is observed experimentally in a GaAs/Al 0.45 Ga 0.55
As superlattice under dc bias at room temperature, which is driven by noise. For an applied …

Semiconductor superlattices are periodic nanostructures consisting of epitaxially grown
quantum wells and barriers. For thick barriers, the quantum wells are weakly coupled and …

It is shown that coherence resonance, a phenomenon in which regularity of noise-induced
oscillations in nonlinear excitable systems is maximized at a certain optimal noise intensity …

Weakly coupled semiconductor superlattices under dc voltage bias are excitable systems
with many degrees of freedom that may exhibit spontaneous chaos at room temperature and …

To simulate a topological neural network handling weak signals via stochastic resonance
(SR), it is necessary to introduce an inherent nonlinearity into nanoscale devices. We use …

Purpose To solve the problem that it is difficult to detect the weak bearing fault signal from
high-intensity noise, a method of bearing fault detection based on the two-dimensional tri …

Stochastic resonance is of great significance for extracting fault signals of bearings. A novel
tri-stable stochastic resonance coupling system driven by dual-input signals (DTDTSR) is …
