Clustering operation, which attempts to partition a set of objects into several subsets that are distinguishable under some criterion of similarity, could significantly ease these operations.
Each oocyte-cyst follows 14 stereotypical consecutive stages of pre-vitellogenic (S1 S7) and vitellogenic (S8 S14) growth, each easily distinguishable by morphological criteria (Spradling et al., 1997).
The performance of different sampling criteria is distinguishable, where CoPerplexity, CommonTag and activeness perform much better than the other three, suggesting that users' hashtag adoption tendency in the past is decisive in attention sampling.
Patients with FTD were more likely to have a family history of dementia (p=0.026), at least one cerebrovascular risk factor (p=0.003), a history of major depression diagnosed using DSM-IV criteria and distinguishable from apathy commonly found in FTD (Fisher's exact p=0.007) and to die during the follow-up period (Pearson χ 8.97, p=0.003).
In these cells the coupling of growth arrest and differentiation occurs at a distinct biological state, and this predifferentiation arrest state is distinguishable by a variety of criteria from other restriction points, such as the growth factor deficiency arrest state and the nutrient deficiency arrest state.
The genotypic cluster criterion defines species as "distinguishable groups of individuals that have few or no intermediates when in contact" (p. 296 [ 39]).
HIAP-I shares a limited number of antigenic epitopes with HIV-1 but is distinguishable by morphological, physical, and biochemical criteria.
Since considerable disagreement exists about the correct identification of individual CTC-like events among experienced operators of the CellSearch® system (Kraan et al, 2011), we grouped all CTC-like events (defined by the CellSearch criteria mentioned above) into four morphologically distinguishable subcategories.
16 17 On endoscopy, if the distal oesophagus looks pink or crimson in colour and is clearly distinguishable from the appearance of a hiatal hernia (fig 2) using accepted criteria such as the Prague endoscopic criteria, 17 then mucosal biopsies should be performed and the samples examined histopathologically.
