Light is the most important time-giver of the external environment for the circadian rhythms of
organisms. Under different light conditions, changes in the rhythmic behavior of organisms …

Many organisms have oscillators with a period of about 24 hours, called “circadian clocks”.
They employ negative biochemical feedback loops that are self-contained within a single …

The signal transduction and amplification in a Neurospora circadian clock system is studied
by using the mechanism of internal signal stochastic resonance (ISSR). Two cases have …

The fungus Neurospora crassa constitutes an important model system extensively used in
chronobiology. Several studies have addressed how environmental cues, such as light, can …

A two variable model with delay in both the variables, is proposed for the circadian
oscillations of protein concentrations in the fungal species Neurospora crassa. The …

Sleep/wake cycles were once dictated by the solar day, but now humans are subjected to
prolonged exposure to artificial light, resulting in altered daily sleep patterns. We investigate …

Daylight plays a major role in the wake/sleep cycle in humans. Indeed, the wake/sleep
system stems from biological systems that follow a circadian rhythm determined by the …

The circadian rhythm affects the biological evolution and operating mechanisms of
organisms. The impact of light on the circadian rhythm is a significant concern for both …

The effect of light noise on a Neurospora circadian clock system in the steady states is
investigated. It is found that the circadian oscillations could be induced by light noise …

Daylight plays a major role in the wake/sleep cycle in humans. Indeed, the wake/sleep
system stems from biological systems that follow a circadian rhythm determined by the …
