A comparative analysis of massive finger-vein recognition algorithms: from energy consumption perspective
; ; ; ; Barrientos, Ricardo
(2022)
The volume of data generated has grown exponentially in recent years worldwide. In general, parallel architectures such as clusters, multicores, and GPUs have reduced processing times compared to their sequential version. ...

A comparison of anthropometric parameters and the body composition of professional soccer players
(2022)The present cross-sectional (comparative) study aimed to compare the anthropometric and body composition parameters in professional soccer players over five seasons. It was conducted on 120 soccer players grouped in a ...
-
A comparison of stochastic gradient MCMC using multi-core and GPU architectures
(2020)Deep learning models are traditionally used in big data scenarios. When there is not enough training data to fit a large model, transfer learning re-purpose the learned features from an existing model and re-train the lower ...

A comprehensive review of extreme learning machine on medical imaging
; Mora, Marco; ; ; ; (2023)
The feedforward neural network based on randomization has been of great interest in the scientific community, particularly extreme learning machines, due to its simplicity, training speed, and levels of accuracy comparable ...

A computational approach to predict the role of genetic alterations in methyltransferase histones genes with implications in liver cancer
(2023)Histone methyltransferases (HMTs) comprise a subclass of epigenetic regulators. Dysregulation of these enzymes results in aberrant epigenetic regulation, commonly observed in various tumor types, including hepatocellular ...

A description of the epidemiological dynamics of Chagas disease via mathematical modeling
; ; Cancino-Faure, Beatriz; ; (2023)
Chagas disease is caused by the protozoan Trypanosoma cruzi, which parasitizes many mammals, including humans. Its vectors are blood-feeding hematophagous triatomine insects of different species, which vary according to ...
-
A family of skew-normal distributions for modeling proportions and rates with zeros/ones excess
(2020)In this paper, we consider skew-normal distributions for constructing new a distribution which allows us to model proportions and rates with zero/one inflation as an alternative to the inflated beta distributions. The new ...
-
A first insight into the structure and function of rhizosphere microbiota in antarctic plants using shotgun metagenomic
(2019)Antarctic vascular plants such as Deschampsia antarctica (Da) could generate more suitable micro-environmental conditions for the establishment of other plants like Colobanthus quitensis (Cq). Although positive plant–plant ...

A framework for building safe and effective school environments: Positive behavioral interventions and supports (PBIS)
(2018)Abstract: Schools throughout the world strive to establish safe and effective learning environments. One consistent challenge is student aggression, acting-out, withdrawal, and insubordination. The historic response to ...
-
A general MIMO VLC channel model for underground mining environments
(2022)Underground Mining (UM) is a harsh environment that involves multiple threats to worker safety and needs adequate wireless communications to ensure worker well-being and optimize miner efficiency. While radio frequency ...
-
A generalized local function in ideal topological spaces
(2022)In this paper we introduce a generalization of the notion of local function using operators associated to the topology. Similarly, a notion of compatibility of the ideal with the topology is introduced utilizing this new ...

A geometric morphometrics and genetics characterization of Vanessa carye in an extreme elevational gradient in the Chilean Altiplano
(2023)The Western Painted Lady butterfly, Vanessa carye (Hüber, 1812), in addition to pre-senting an extensive distribution in South America, has been observed flying in the Chilean Alti-plano from the coast to the highlands, ...
-
A global phylogeny of butterflies reveals their evolutionary history, ancestral hosts and biogeographic origins
(2023)Butterflies are a diverse and charismatic insect group that are thought to have evolved with plants and dispersed throughout the world in response to key geological events. However, these hypotheses have not been extensively ...
