We also give a bottom-up description of how temporal identities all arise from the notion of distinct events situated in time and the durations separating them.
Schul et al. [57] revealed the pause duration separating pairs of syllables in the songs of T. viridissima as a critical song parameter for species recognition.
The minimum silence duration separating two utterances was set to 0.5 s like in NIST RT '04[11], since pauses smaller than this value were not considered to be segmentation breaks in a speaker's speech (it is also complementary to the scoring collar discussed later).
In contrast, the average pause duration separating pairs of syllables was only slightly longer at 21°C compared to 28°C (22 ms vs. 18 ms).
A rigorous statistical methodology has been defined for the identification of the beginning of the triggering event, based on the critical duration, i.e. the minimum dry period duration separating two stochastically independent rainy periods.
We chose to analyse according to comparator (placebo or active) and trial duration, separating short-term trials of less than six weeks, from those of six to 12 weeks.
The subjects performed three MVCs with 3 5 s duration, separated by 1 min rest.
To test if the phenotype of diminished adaptation in eNOS-deficient mice is also detectable with longer interstimulus intervals we stimulated the OE with two, longer odorant pulses (2 s duration) separated by a long interstimulus interval (28 s).
The treatment and placebo intervals were 2 weeks in duration separated by a 4-week washout period.
Instead of using shaped pulses, our pulse sequence was composed of a train of 50 rectangular pulses of τ = 20 μs length each (1 ms total pulse duration), separated by 5 μs and repeated with the repetition rate t 0== 100 ms (Figure 7), yielding the duty cycle δ D = 0.01.
After the fixation display that lasted 1000 ms duration, there were two stimulus intervals of 150 ms duration, separated by a blank display of 350 ms. The contrast increment was present in only one of these intervals, randomly selected.
