The positive properties of both estimators rely on characteristics of information by definition unmeasured in observational studies.
Different imaging modalities that rely on characteristics other than size such as dynamic contrast-enhanced (DCE) ultrasonography, DCE CT, DCE magnetic resonance imaging (MRI), diffusion-weighted MRI, positron emission tomography and texture analysis seem to contribute with prognostic information, even at baseline scans, and can predict tumour response early after initiating therapy.
However, the majority of patients did not have a pulmonary test performed within one year before ICU admission, thus we also had to rely on characteristic findings in the history and physical examination by the attending physician at the time of ICU admission, as is often done in studies of COPD.
The main difference among these BSs relies on characteristics such as the transmit power, physical size, size of coverage areas, and cost, among others.
Referential opacity is possible, which in turn relies on characteristics, and this fulfills the second criterion.
A multistep functionalization protocol is described relying on characteristic changes in the stress response as a function of probe density to in situ electrochemical stimulation.
The ECP method heavily relies on characteristic positional absence of nucleotide base types.
These systems rely on soil characteristics, the characteristics of wastewater, topography, the presence of additional media in soil, and so forth.
Before the emergence of molecular identification approaches, one determines taxonomic status and phylogenetic relationships of animals mainly rely on morphological characteristics.
Ants, bees and wasps form complex communities but do not seem to rely on facial characteristics for their communication.
At the moment, military systems tend to rely on physical characteristics such as scanners that recognises users' palms, face, DNA or irises.
