"It's a really clean experiment," says Joseph McCarthy, a chemical engineer at the University of Pittsburgh in Pennsylvania, "a real nice one to sit down and look at analytically".
"That was a very clean experiment," says Massagué.
Still, to the extent that we do not have a clean natural experiment, our findings must be interpreted with caution.
A 60 cm × 70 cm × 60 cm copper block, without any shield, results suitable for conducting a "clean" benchmark experiment.
For the sake of clarity we compare the two models in a clean synthetic experiment of a hypothetical pandemic event for which we assume the same parameterization with regards to the modeling aspects that the models share, such as disease progression and initial conditions.
The conclusions are based on elegantly designed, very clean experiments where the side chain of interest is added into the WT or the minimal background, and effect of k cat /KM measured.
The continent, in other words, was seen as something of a clean slate for experiments in terror prevention. .
To be sure, the nascent wireless Internet industry and the dot-coms have one thing in common -- that their development resembles more a route littered with failed experiments than a clean Roman road.
Fifteen to 20 flies per assay were placed in a clean tube 24 h before the experiment.
Nevertheless, we believe these in-silico experiments do provide a clean and reliable estimate of the possible errors in estimated parameters using relative pressure measurements.
