Condition-based monitoring and machine fault detection play important roles in industry as
they can ensure safety and reduce breakdown loss. Weak signal detection is an essential …

Although typically assumed to degrade performance, random fluctuations, or noise, can
sometimes improve information processing in non-linear systems. One such form …

Stochastic resonance is said to be observed when increases in levels of unpredictable
fluctuations—eg, random noise—cause an increase in a metric of the quality of signal …

Fault detection is a key tool to ensure the safety and reliability of machinery. In machinery
fault detection, signal processing methods are extensively applied to extract fault …

Variability in the environment defines the structure and dynamics of all living systems, from
organisms to ecosystems. Species have evolved traits and strategies that allow them to …

The influence of bounded noise and time delay on the sub–threshold signal transmission in
FitzHugh–Nagumo neuronal networks is studied in this paper. It is found that the signal …

Organisms can sense subtle changes in the environment around them such as temperature,
vibration and magnetic field. That is because biological neural network interconnected …

A continuously growing body of evidence indicates that astrocytes, which is the most
abundant sub-type of glial cells in the nervous system, not only provide structural and …

Chemical and electrical interaction within and between the cells is well established and
studied. Just the opposite is truth about the cellular interactions via other physical fields. The …

A regular heartbeat is essential to vertebrate life. In the mature heart, this function is driven
by an anatomically localized pacemaker. By contrast, pacemaking capability is broadly …
