Restoration of retinal images with space-variant blur
(2014)
Retinal images are essential clinical resources for the diagnosis of retinopathy and many other ocular diseases. Because of improper acquisition conditions or inherent optical aberrations in the eye, the images are often ...
IMMAN: free software for information theory-based chemometric analysis
(Kluwer Academic Publishers, 2015)
Abstract: The features and theoretical background of a new and free computational program for chemometric analysis denominated IMMAN (acronym for Information theory-based CheMoMetrics ANalysis) are presented. This is ...
Relational Agreement Measures for Similarity Searching of Cheminformatic Data Sets
(Institute of Electrical and Electronics Engineers Inc., 2016)
Research on similarity searching of cheminformatic data sets has been focused on similarity measures using fingerprints. However, nominal scales are the least informative of all metric scales, increasing the tied similarity ...
Features of dengue and chikungunya infections of colombian children under 24 months of age admitted to the emergency department
(Oxford University Press, 2018)
We aimed to assess clinical and laboratory differences between dengue and chikungunya in children <24 months of age in a comparative study. We collected retrospective clinical and laboratory data confirmed by NS1/IgM for ...
Novel 3D bio-macromolecular bilinear descriptors for protein science: Predicting protein structural classes
(Academic Press, 2015)
In the present study, we introduce novel 3D protein descriptors based on the bilinear algebraic form in the ℝn space on the coulombic matrix. For the calculation of these descriptors, macromolecular vectors belonging to ...
Generalized molecular descriptors derived from event-based discrete derivative
(Bentham Science Publishers B.V., 2016)
In the present study, a generalized approach for molecular structure characterization is introduced, based on the relation frequency matrix (F) representation of the molecular graph and the subsequent calculation of the ...
Overlap and diversity in antimicrobial peptide databases: Compiling a non-redundant set of sequences
(Oxford University Press, 2015)
Motivation: The large variety of antimicrobial peptide (AMP) databases developed to date are characterized by a substantial overlap of data and similarity of sequences. Our goals are to analyze the levels of redundancy for ...
Physico-Chemical and structural interpretation of discrete derivative indices on N-tuples atoms
(MDPI AG, 2016)
This report examines the interpretation of the Graph Derivative Indices (GDIs) from three different perspectives (i.e., in structural, steric and electronic terms). It is found that the individual vertex frequencies may ...
