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.
Science
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).
Science
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.
Science
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.

Treatment consisted of 10 consecutively TMS sessions delivered on left dorsolateral prefrontal cortex, each session being 10 trains of 2-s duration, separated by 30-s pause, 20 Hz frequency, 100% motor threshold intensity.
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.

Ludwig's WRAP-UP
The phrase "duration separating" is a somewhat uncommon phrase primarily used in scientific and technical contexts to describe the length of time between two events. While grammatically acceptable, it is more formal and less frequently used in everyday language. As Ludwig AI points out, it might be clearer to use alternatives such as "interval between" or "period between" in many cases. When precision is crucial, especially in scientific writing, "duration separating" can effectively specify the temporal relationship. However, writers should be mindful of potential ambiguity and consider whether a more common phrase would better serve their audience.
