As described in our in vivo results, the mean rate smoothly declined with increase in λthr, and the number of AP cascades of PN groups peaked in rate at an intermediate threshold λthr for all three conditions.
Like most stochastic natural processes, intracranial EEG is characterized by a "1/ f" or "red noise" spectrum, meaning that power is greatest at lower frequencies and smoothly declines with increasing frequency.
This parameter space generalizes the parametric models given in (4) and (5), since it is possible for the π j 's to decline smoothly, or abruptly, or both.
All the curves start rising at first, decline smoothly for a moment when reach the top valve, and fall down to the bottom sharply.
In a pilot study in our lab, for example, radiologists' ratings of the quality of the head CT declined smoothly with reduction in dose but their performance on a stroke detection task was closer to a step function.
In contrast with the other networks, the FOSISS network lacks the sharp reduction of cooperators, instead this population declines smoothly and progressively; especially, when it reaches a (nu approx 0.25), cooperators decrease in a less dramatic manner all the way to (nu approx 0.5).
The air flow upstream from a running spider declines smoothly with distance (Figure 4); a constrained regression, using the function given in (Eq. 2) and the independently measured mean spider's velocity as a fixed parameter, lead to a good fit over the whole range of distances (R2 = 0.80).
In September, however, modeled constituent values did not decline smoothly with the incoming tide.
A review of published studies casts doubt on those assumptions, and our laboratory experiments on cane toads (Rhinella marina) show that brain activity declines smoothly during freezing, with no indication of pain perception.
And that the terms "modernism," "modernist," "postmodernism," and "postmodernist" all experienced a giddy ascent in the early nineteen-eighties, and have been in a pattern of smoothly inexorable decline since the late nineties.
