3GPP connects the in-channel selectivity with a throughput requirement: the throughput in the presence of the interferer shall be ≥95%% of the maximal throughput achievable in a reference measurement without the presence of an interferer.
For example, an inclusion of anticipated increased harvesting levels for the production of bioenergy (as potentially achievable by a suitable reference scenario) would cause a gross violation of the meaning of reference levels in reflecting BAU activities.
As a matter of fact, optimal performance operation (e.g. maximal efficiency, maximal torque, unitary power factor…) are not achievable using constant flux reference especially when facing wide range load variations.
Encouragingly, the taxonomic resolution power will only improve further as (1) read lengths increase –250 bp are now possible, and 450 bp will soon be achievable; and (2) rRNA reference databases compile ever more sequences.
Finally, our results may serve as a reference for achievable survival rates and evaluations of complication rates in nonimmune individuals in resource-poor settings, where the investigations needed to characterize complications may be unavailable (e.g., routine high-quality chest X-ray, neuro-imaging studies, routine blood cultures, and hemodynamic measurements).
Correlation with whole liver pathology at autopsy or after transplantation is rarely achievable, so the best reference standard for most imaging studies is surgical exploration with intra-operative ultrasound.
Although health care providers may have tools to educate their patients about the impact of quitting smoking, they may still be lacking points of reference and achievable benefits of behavioural change that can be discussed with patients.
Technically, the influence of the weights in the solution generated by the achievement scalarizing function is different, depending on whether the reference point is achievable or not.
Obama achieved the achievable.
Use of the clinical course as a reference standard is achievable in primary-care practice and is not subject to bias, as long as follow-up is complete for all patients.
