To compare first-trimester versus second-trimester screening procedures on a common basis, we used a fixed detection rate, which is more applicable than a fixed false-positive rate because applying the latter to the first-trimester as compared with the second-trimester results in a different detection rate, notably from the spontaneous losses of DS foetuses between the first and second trimesters.
To characterize the difference between useful signal and noise in a per-voxel per-frequency basis, we used an estimated threshold of 1.2× effective noise.
Second, instead of assessing functional homogeneity on a term by term basis we use all the annotations available within a given ontology.
On a daily basis, we use some fairly advanced features of UNIX to make our work easier, and we are always looking for ways to let the computers do more work, more efficiently.
On a daily basis, we use social media to engage, inform, and inspire youth in more than 100 countries and in over 10 languages.
On that basis we used the Yale University Cohort as a training set to generate a cutpoint that provides the optimal separation in terms of survival - an AQUA score of 18.8 was thus selected- and validated this cutpoint on the Greek Lung Cancer Cohort (validation set).
On that basis, we used RDS to assemble a sample of PLHA from five cities in Peru, with the goal of assessing HIV-related health care access, and exploring the relationship between such access and key socio-demographic and socio-economic determinants.
In order to calculate the number of nonsynonymous substitutions per nonsynonymous site on a lineage-by-lineage basis, we used the reconstructed phylogeny and a maximum-likelihood method (F3×4 model) implemented in codeml from the PAML package (Yang 2007).
As a basis, we used the educational framework of the Accreditation Council for Graduate Medical Education (ACGME) [ 19], which focuses on three domains: objectives, methods and evaluation.
