Parallel connected-Component-Labeling based on homotopy trees
(Elsevier, 2020)
Taking advantage of the topological and isotopic properties of binary digital images, we present here anew algorithm for connected component labeling (CLL). A local-to-global treatment of the topologicalinformation within ...

Parallel homological calculus for 3D binary digital images
(Springer, 2024-01-29)
Topological representations of binary digital images usually take into consideration different adjacency types between colors.Within the cubical-voxel 3D binary image context, we design an algorithm for computing the ...

Neonatal exposure to androgens dynamically alters gut microbiota architecture
(BioScientifica, 2020)
Gonadal steroids strongly contribute to the metabolic programming that shapes the susceptibility to the manifestation of diseases later in life, and the effect is often sexually dimorphic. Microbiome signatures, together ...

Building Hierarchical Tree Representations Using Homological-Based Tools
(Springer, 2021)
A new algorithm for computing the α-tree hierarchical repre sentation of a grey-scale digital image is presented here. The technique is based on an efficient simplified version of the Homological Spanning For est (HSF) ...

An altered microbiota pattern precedes Type 2 diabetes mellitus development: From the CORDIOPREV study
(Elsevier, 2021)
Introduction A distinctive gut microbiome have been linked to type 2 diabetes mellitus (T2DM). We aimed to evaluate whether gut microbiota composition, in addition to clinical biomarkers, could improve the prediction of ...

On the Topological Disparity Characterization of Square-Pixel Binary Image Data by a Labeled Bipartite Graph
(Springer, 2022)
Given an nD digital image I based on cubical n-xel, to fully characterize the degree of internal topological dissimilarity existing in I when using different adjacency relations (mainly, comparing 2n or 2n −1 adjacency ...

Sex-specific differences in intestinal microbiota associated with cardiovascular diseases
(BMC, 2024-01-19)
Background Cardiovascular diseases (CVD), including coronary heart disease (CHD), display a higher prevalence in men than women. This study aims to evaluate the variations in the intestinal microbiota between men and ...

Generating (co)homological information using boundary scale
(Elsevier, 2020)
In this paper we develop a new computational technique called boundary scale-space theory. This tech- nique is based on the topol1 ogical paradigm consisting of representing a geometric subdivided object K using a one-parameter ...

Interplay between gonadal hormones and postnatal overfeeding in defining sex-dependent differences in gut microbiota architecture
(Impact Journals, 2020)
Aging is associated with a decline in sex hormones, variable between sexes, that has an impact on many different body systems and might contribute to age-related disease progression. We aimed to characterize the sex ...
