With new technology, it announced in a news release, "we are now recognizing faces and reading license plates from stand-off ranges beyond audible detectability".
Thus, Dr. Bernick's group concluded, the lag between detectability and physical symptoms probably occurs sometime during those six years.
"The fact that it's been around for a few thousand tests and only one positive suggests that either there's much less growth hormone being used than we thought, which is doubtful, or the period of detectability is really pretty short -- a few hours; it's probably the latter," Catlin said.
"In such situations, people must rely on their instincts to make a call, which should increase the use and the detectability of a player's height as an additional decision cue.
As the report notes: "While Dr Rodchenkov's 'cocktail' may sound fanciful... steroids dissolve better in alcohol than in water, and the administration of steroids through bucal absorption, as compared to injection or swallowing the drug, does shorten the window of detectability".
But the 3D printing technology that the NRA referred to can be used to create a gun that slips through the old law's loopholes; its "detectability" would consist only of a removable metal pin, something that could easily be discarded.
EPO is hard to detect, said Dr. Gary Wadler, an international drug expert and a professor of medicine at New York University, because the "effect of the drug outlasts its detectability".
"It was below the level of detectability, but there can still be some leukemia cells present".
Even with the detectability of EPO, the use of performance-enhancing drugs is likely to be extensive at the Sydney Games.
In this more liberal sense we can say that there is an analogy between sound and light because echoes are similar to reflections, loudness to brightness, pitch to color, detectability by the ear to detectability by the eye, and so on.
