With nuclear or biological weapons, the technical threshold is high.
"The emergence of a … corridor directly over the north pole indicates that sea ice will become sufficiently thin such that a critical technical threshold is surpassed, and the shortest great circle route thus becomes feasible, for ships with moderate ice-breaking capability," says the paper.
President Mahmoud Ahmadinejad told a major rally of supporters that Iran had succeeded in enriching a first batch of uranium to a level of 20% (crossing a technical threshold which opens the way to weapons-grade purity), and thus Iran had become "a nuclear state".
A method technical threshold was set to 90% similarity, above which significant differentiation of the isolates was not possible.
This analysis extends the sample to persons aged 20 65 years and also includes part-time workers to have enough variation in the technical threshold across municipalities.
The custom assay was optimized against bisulfite sequencing as described [ 56], resulting in the conservative technical threshold of Dm ≥ 0.15 for methylation detection.
The Dm value of 0.15 or above (corresponding to 15%% of methylated DNA) was treated as the conservative technical threshold for methylation detection [ 49].
