Assignment to experimental conditions followed a predetermined blocked randomisation sequence that ensured equal numbers of participants per condition.
The starting mask was predetermined by block randomisation so as to eliminate a systematic error from 'training' effects.
This paper first derives the so-called minimum power equation (MPE) to solve for the minimum transmit power required for attaining a given outage rate probability of a single-user MIMO block-fading channel if the number of blocks is predetermined.
Allocation is done by the biometrician based on a predetermined list generated with a blocked randomization SAS procedure with a fixed block size, stratified by age (< 50 / ≥ 50 years of age) and baseline physical fatigue level (< 14 / ≥ 14).
Patients complying with these inclusion/exclusion criteria were randomised 1 to 1 within each centre with a predetermined randomisation list in balanced blocks, to receive frovatriptan 2.5 mg or rizatriptan 10 mg, zolmitriptan 2.5 mg, and almotriptan 12.5 mg, respectively.
That means scouring predetermined locations, including certain city blocks and back alleys "to make sure that we don't miss anyone that is parked in their car or are on the streets," said Ivet Samvelyan, a manager with Glendale's community services and parks department, who said she encountered more seniors during the recent count.
Given that task-set in PRBs is predetermined (i.e. color in color blocks; shape in shape blocks) and remains constant over the course of 24 trials, task cues and stimulus valence are theoretically irrelevant for performance.
To prevent this, we only take into account the blocks whose average differences with the currently denoised block are smaller than some predetermined threshold Dmax.
After predetermined incubation periods, proteolytic activity was blocked by adding 1 µl of PMSF, a serine protease inhibitor, to reach a final concentration of 1 mM.
Subsequently, the tissue cylinder was re-embedded into a predetermined position in a recipient paraffin block.
