Acompañamiento Familiar Mediado por TIC y Desempeño Académico en Grado Octavo

Gleyra Yudith Martínez Sanches · María Cristina Martínez Reyes

This article presented the results of a project developed as a requirement for the Master’s Degree in Information and Communication Technologies in Education. Its purpose was to analyze the relationship between ICT-mediated family support and the academic performance of eighth-grade students in an educational instituti...

Macroseismic and seismotectonic analysis of the Mw 6.1 August 17, 2023 earthquake in the central region of Colombia

Elkin de J. Salcedo-Hurtado · Augusto Antonio Gómez-Capera · Carlos A. Vargas-Jiménez · Germán Chicangana-Montón · y 2 más

This study conducts a complementary analysis of instrumental and macroseismic data regarding the August 17, 2023, earthquake in the central region of Colombia. This event is part of a historical earthquake sequence in the region, with an intensity higher than VII EMS‑98, which has caused considerable material damage in...

Inflammaging and Immunosenescence: The New Biological Paradigm of Periodontal Disease in Older Adults. Narrative Review

Maria Angelica Zambrano · Carmen Hernandez Ojeda · Karen Osorio Oritz · Rocio Diaz Hernandez · y 2 más

Periodontitis has long been described as a chronic inflammatory disease driven by the interaction between a dysbiotic biofilm and an altered host immune response. This model, however, does not fully explain the greater susceptibility, faster progression and poorer treatment response observed in older adults. From a ger...

New zircon U–Pb ages and their problems in the integration of the Geological Map of Colombia

Jorge Gómez · Daniela Mateus-Zabala · Montes Ramírez Nohora

The Geological Map of Colombia is periodically updated by the Colombian Geological Survey to incorporate advances in geological mapping, geochronology, and tectonic interpretations. The 2023 edition integrates geological information published up to March 2022 and includes a comprehensive reassessment of isotopic ages,...

Measurement of the t-channel single top quark cross section in proton-proton collisions at $$ \sqrt{s}=5.02 $$ TeV

Hayrapetyan, Aram · Makarenko, Vladimir · Tumasyan, Armen · Adam, Wolfgang · y 195 más

A bstract The single top quark t -channel production cross section is measured in proton-proton collisions at the CERN LHC at $$ \sqrt{s}=5.02 $$ s = 5.02 TeV, using data recorded with the CMS detector in 2017, corresponding to an integrated luminosity of 302 pb − 1 , and resulting in the first CMS measurement of the p...

3-Hydroxyflavone-Containing Chitosan/Poly(Vinyl Alcohol) Films: UV-A Response, Water-Related Behavior, and DFT/Multiwfn Descriptors of Isolated Components

Joaquín Alejandro Hernández Fernández · Juan Jose Carrascal · Jose Alfonso Prieto Palomo

Hydrophilic polymer films containing environment-sensitive chromophores are useful model systems for examining optical responses in polar matrices. In this study, chitosan/poly(vinyl alcohol) (CS–PVA) films containing low nominal loadings of 3-hydroxyflavone (3HF; 0.05–0.20 wt.%) were prepared by solution casting and c...

Electrodermal Activity as a Potential Diagnostic Biomarker for Alzheimer’s Disease: A Pilot Study

Sibi Pandian · Luis R. Mercado-Diaz · Jonathan Ruiz-Trivino · David Aguillon · y 1 más

Alzheimer’s disease (AD), the leading cause of dementia, lacks an inexpensive and non-invasive method for early detection. Here, we investigate whether electrodermal activity (EDA), a measure of changes in electrical conductance at the skin’s surface, can offer a convenient avenue for AD screening by capturing the auto...

A Hybrid Deep Learning and Image-like Framework for Fetal Heart Rate Estimation Using Phonocardiography Signals

Ernesto Moya-Albor · Sandra L. Gomez-Coronel · Jorge Brieva · Alberto Lopez-Figueroa · y 1 más

One of the most important parameters in fetal monitoring is the fetal heart rate (fHR). However, due to the nature of this signal, several non-invasive techniques have been developed for fetal monitoring, including Cardiotocography (CTG), Doppler Echocardiography (Doppler Echo), fetal electrocardiography (fECG), fetal...
