Topo-Geometric Filtration Scheme for Geometric Active Contours and Level Sets: Application to Cerebrovascular Segmentation
(Springer, 2014)
One of the main problems of the existing methods for the segmentation of cerebral vasculature is the appearance in the segmentation result of wrong topological artefacts such as the kissing vessels. In this paper, a new ...

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 ...

Representing the Surface of Objects by Combinatorial Pyramids
(Czech Pattern Recognition Society, 2010)
This paper introduces a new method to rep- resent the surface of objects using two dimensional com- binatorial maps. The classical de nition of two dimen- sional combinatorial maps is extended here by adding a \back ...

Searching combinatorial optimality using graph-based homology information
(2015)
This paper analyses the topological information of a digital object O under a combined combinatorial-algebraic point of view. Working with a topology-preserving cellularization K(O) of the object, algebraic and combinatorial ...

Sex Differences in the Gut Microbiota as Potential Determinants of Gender Predisposition to Disease
(Wiley, 2019)
Scope: Dysbiosis of gut microbiota is involved in metabolic syndrome (MetS) development, which has a different incidence between men (M) and women (W). The differences in gut microbiota in MetS patients are explored ...

Circulating miRNAs as predictive biomarkers of type 2 diabetes mellitus development in coronary heart disease patients fromt he CORDIOPREV study
(American Society of Gene and Cell Therapy, 2018-09)
Circulating microRNAs (miRNAs) have been proposed as type 2 diabetes biomarkers, and they may be a more sensitive way to predict development of the disease than the currently used tools. Our aim was to identify whether ...

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 ...

Triangle mesh compression and homological spanning forests
(2012)
Triangle three-dimensional meshes have been widely used to represent 3D objects in several applications. These meshes are usually surfaces that require a huge amount of resources when they are stored, processed or transmitted. ...

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 ...
