Hydrophobicity identifies false positives and false negatives in peptide-MHC binding [PDF]

Frontiers in Oncology, 2022
Major Histocompability Complex (MHC) Class I molecules allow cells to present foreign and endogenous peptides to T-Cells so that cells infected by pathogens can be identified and killed. Neural networks tools such as NetMHC-4.0 and NetMHCpan-4.1 are used

All tests are imperfect: Accounting for false positives and false negatives using Bayesian statistics [PDF]

Heliyon, 2020
Tests with binary outcomes (e.g., positive versus negative) to indicate a binary state of nature (e.g., disease agent present versus absent) are common.

False negatives in GBA1 sequencing due to polymerase dependent allelic imbalance [PDF]

Scientific Reports, 2021
A variant in the GBA1 gene is one of the most common genetic risk factors to develop Parkinson’s disease (PD). Here the serendipitous finding is reported of a polymerase dependent allelic imbalance when using next generation sequencing, potentially ...

Prototype based contrastive graph clustering network for reducing false negatives [PDF]

Scientific Reports
Contrastive graph clustering methods significantly enhance the clustering performance of graph data by leveraging multi-view augmentation and contrastive loss. In particular, Self-Supervised Graph Contrastive Learning (SS-GCL) has gained attention due to

False positives and false negatives measure less than 0.001% in labeling ssDNA with osmium tetroxide 2,2’-bipyridine [PDF]

Beilstein Journal of Nanotechnology, 2016
Osmium tetroxide 2,2’-bipyridine (OsBp) is known to react with pyrimidines in ssDNA and preferentially label deoxythymine (T) over deoxycytosine (C). The product, osmylated DNA, was proposed as a surrogate for nanopore-based DNA sequencing due to OsBp’s “
