    • Features of dengue and chikungunya infections of colombian children under 24 months of age admitted to the emergency department 

      Paternina-Caicedo A.; De la Hoz-Restrepo F.; Díaz-Quijano F.; Caicedo-Torres W.; Badillo-Viloria M.A.; Bula-Anichiarico D.; Alvis-Guzmán N.; Mattar S.; Constenla D.; Pinzón-Redondo H. (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 ...

    • Generalized molecular descriptors derived from event-based discrete derivative 

      Martínez-Santiago O.; Cabrera R.M.; Marrero-Ponce Y.; Barigye S.J.; Le-Thi-Thu H.; Torres, Javier; Zambrano C.H.; Yaber Goenaga, Iván; Cruz-Monteagudo, M.; López Y.M.; Giménez F.P.; Torrens, F. (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 ...

    • IMMAN: free software for information theory-based chemometric analysis 

      Urias R.W.P.; Barigye S.J.; Marrero-Ponce Y.; García-Jacas C.R.; Valdes-Martiní J.R.; Perez-Gimenez F. (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 ...

    • Implementation of an image based focusing algorithm for non-mydriatic retinal imaging 

      Marrugo A.G.; Millan M.S.; Abril H.C. (Institute of Electrical and Electronics Engineers Inc., 2014)
      Retinal photography is important for the assessment of eye diseases. The task of fine focusing the image is demanding and lack of focus is often the cause of suboptimal photographs. The advent of digital cameras has provided ...

    • Multispectral tracking of phytoplankton in the Colombian Caribbean 

      Caicedo V.V.O.; Gómez A.P. (2004)
      In a quantitative research study, the concentration and circulation of group of micro-organisms "phytoplankton" have been found through the images of the ocean colour in the Colombian Caribbean Sea. These images have been ...

    • Novel 3D bio-macromolecular bilinear descriptors for protein science: Predicting protein structural classes 

      Marrero-Ponce Y.; Contreras-Torres E.; García-Jacas C.R.; Barigye S.J.; Cubillán, Néstor; Alvarado Y.J. (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 ...

    • Overlap and diversity in antimicrobial peptide databases: Compiling a non-redundant set of sequences 

      Marrero-Ponce, Y.; Marrero-Ponce, Y.; Tellez-Ibarra, R.; Llorente-Quesada, M.T.; Salgado, J.; Barigye, S.J.; Liu, J. (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 

      Martínez-Santiago, O.; Marrero-Ponce, Y.; Barigye, S.J.; Thu, H.L.T.; Torres, Javier; Zambrano, C.H.; Muñiz Olite, J.L.; Cruz-Monteagudo, M.; Vivas-Reyes, R.; Infante, L.V.; Artiles Martínez, L.M. (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 ...

    • Relational Agreement Measures for Similarity Searching of Cheminformatic Data Sets 

      Rivera-Borroto O.M.; García-De La Vega J.M.; Marrero-Ponce Y.; Grau R. (Institute of Electrical and Electronics Engineers Inc., 2016)
