DOI: 10.1002/hbm.23419
Abstract: Neuroimaging research involves analyses of huge amounts of biological data that might or might not be related with cognition. This relationship is usually approached using univariate methods, and, therefore, correction methods are mandatory for reducing… read more here.

DOI: 10.1016/j.physa.2018.09.112
Abstract: Abstract In previous studies, the heterogeneity of complex networks has been extensively studied. In our study, the heterogeneity of distance matrices is studied based on the Renyi index of networks. We define a new metric… read more here.

DOI: 10.1371/journal.pone.0263566
Abstract: 3D protein structures can be analyzed using a distance matrix calculated as the pairwise distance between all Cα atoms in the protein model. Although researchers have efficiently used distance matrices to classify proteins and find… read more here.
