However the shape, in particular, the size of drug (medicine) is empirically decided in the present stage, which will be related to a question how much medicine should be dosed.
It was empirically decided to use three previous background subtracted frames for motion persistence filtering.
Additionally, genes with consistently low expressing signal across all ten developmental stages were removed using a minimum threshold of 0.712, empirically decided using GeneSpring's Cross Gene Error Model.
In two cases, with severely compromised clinical conditions, only one imaging study was feasible and long term antibiotic therapy (4-6 wasks) was empirically decided on the basis of the first FDG-PET/CT scan.
Since increasing N would also increase the ratio of false positives in profiles, it was empirically decided that the sensitivity and specificity of expression profiles were optimally balanced at N = 60.
In our experiment, the term E I is computed as the sum of the negative Normalized Cross-Correlation of each corresponding image patch, the term E s is computed as Euclidean distance between two translations, and the choices of weight coefficients α and β are empirically decided.
Through careful evaluation of the effects of penalty values from a practical point of view, we empirically decided to use a single penalty value of 1.0 throughout this study unless otherwise noted, because it seemed to give, in most cases, a good balance between sensitivity and specificity in domain detection.
Empirically, we decided against IV-technique since the problem of weak instruments was present.
If the former, the issue is, at least in principle, empirically decidable; if the latter, the issues must be decided, if they can be decided, by arguments about value.
Thus, it is left to the designer to decide empirically how to provide the system with redundancy, which is necessary in case of equipment failure.
