Like humans, slumbering animals pass through different stages of sleep, and most mammals exhibit periods of R.E.M. sleep, characterized by intense activity in the brain similar to that during waking, and rapid movements of the eye.
For certain transmission periods, this response may exhibit period-doubling and chaos, leading to increased peaks.
Its 5%and9595% GLUE bounds, obtained considering a multi-objective approach, provide the narrowest band for streamwater nitrogen, which suggests increased model robustness, though all models exhibit periods of inconsistent good and poor fits between simulated outcomes and observed data.
These animals exhibit periods of apparent mania and periods of obvious depression.
Spike responses often exhibit periods of suppressed activity following the initial burst, regardless of flash origin.
It is not possible to record resting metabolic rates over shorter periods in this species, as some individuals exhibit periods of spiracular closure lasting several minutes (Schimpf et al., 2009; Matthews and White, 2011; Schimpf et al., 2012).
These physiological cycles most frequently exhibit periods of 2 6 hr, adopting harmonics of the 24-hr daily light dark cycle or the endogenous circadian rhythm, when external timing cues are absent.
Numerical simulations show the system exhibits period vibration, double period vibration and quasi-period motion.
With the flow velocity as bifurcation parameter, the system exhibits period 1 motion without dual, bifurcating into dual period 1 motions which period double into dual period 2, 4, 8 motions, etc., leading to chaos as the flow velocity is increased.
