Megathermal regimes, which are controlled by systematic fluctuations in seasonal rain, and microthermal regimes, which are controlled by seasonal release of meltwater, may be more reliable than mesothermal regimes.
As can be seen in the figure, the index parameter medians do not show any systematic fluctuations from standard values of 1.0, 1.0, and 0.0, respectively.
The ECT output indicated that there were two types of systematic fluctuations in the time series of mass flow rate and concentration.
The notion is that the series can be decomposed into four elements: Trend (T t )—long-term movements in the mean; Seasonal effects (I t )—cyclical fluctuations related to the calendar; Cycles (C t )—other cyclical fluctuations (such as a business cycles); Residuals (E t )—other random or systematic fluctuations.
Others have reported systematic fluctuations in intraday volatility (see [18] and references within), but these fluctuations closely mimic trading activity within the day.
Given that the plane of anaesthesia evoked by urethane is correlated to its blood concentration and that prior studies of the metabolism of urethane have demonstrated a slow and consistent rate of metabolic excretion in rodent blood samples (without any evidence of systematic fluctuations) [15] it is difficult to understand how variations in anaesthetic level might occur in this situation.
Moreover, the technique allowed the measurement of systematic fluctuations in the ionic current as small as 0.9 ± 0.04 pA.
Significantly, we are able to identify step changes in the current as small as 0.9 ± 0.04 pA, which result from systematic fluctuations in measuring sequential thymine bases at the start of the sequence.
Figure 9 shows substantial lack of fit for GLM, systematic fluctuations from 0. This is due to pooling across years to estimate the yearly seasonal component, which can be quite different from one year to the next.
Therefore the non-systematic fluctuations across the different K-values are attributable to small probably random fluctuations of e incompl, K (s ) and e full, K (s ) over K, which could overshadow a potential dependency on K.
