Moreover, it is impossible to say whether the factors resulting in punctate clades are common or rare: in many cases bacterium-to-eukaryote transfers have been inferred from data with seemingly simple distributions, but it is possible that some of these distributions only appear simple because of sampling deficiency.
There is no direct indication that the additional reference shapes resulted from anything more than sampling deficiency, i.e., were not directly attributable to the size or flexibility of molecules.
Such sampling deficiencies lead to much fewer images in the photo collection depicting scenes in-between landmarks of interest.
For pulmonary NTM disease, it is recommended that multiple cultures be obtained over time (21 ) to rule out transient colonization and avoid sampling deficiencies.
Such sampling deficiencies probably introduce little, if any, bias into statistical tests of positive selection, but could have substantial impacts on the estimation of duplication and gene-loss rates.
For the limitations above, in this paper, we proposed a strategy of dataset remodeling by transferring parameters of ResNet-101 layers trained on the ImageNet dataset to initialize learning model and adopt an augmented data variation approach to overcome the overfitting challenge of sample deficiency.
This is an artefact, in that, F29 is a default diagnosis for ambiguous cases and in the case of the historical sample deficiencies in the records contributed to a greater difficulty in being certain of the diagnosis in a small minority of cases.
Not all plasma samples were examined for MMP1, MMP8 as well as MMP13 due to sample volume deficiency or technical problems with some samples.
In such a sample, heterozygote deficiency generated by the interfamily Wahlund effect may mask the heterozygote excess, reducing the usefulness of the heterozygote-excess method (Luikart and Cornuet 1999).
Particularly interesting seems that, in both in vitro and in vivo settings, using various cell types, primary neuronal cultures as well as murine brain samples, PSEN deficiency was shown to result in endolysosomal autophagic abnormalities [ 33, 37, 69, 97, 164].
When testing samples from deficiency case pedigrees with a limited number of markers and no additional family members available, a clear result indicating maternal relatedness will only be yielded if they are as close as mother child, siblings or monozygotic twins.
