Drivers of Wave Attenuation by Mangroves across contrasting geomorphic settings in Colombia

Maria Fernanda Acosta-Silva · David Alejandro Sánchez-Núñez · Cesar David Padilla Mendoza · Jose Ernesto Mancera-Pineda

Abstract Mangroves provide vital coastal protection, yet their wave attenuation capacity is strongly modulated by forest structure and hydrodynamics—factors that typically vary across coastal geomorphic settings. However, empirical comparisons of wave attenuation rates among contrasting geomorphic settings remain scarc...

O corpo em colapso: complicações neurológicas secundárias à anorexia nervosa em adolescente

José Antonio Coba Lacle · Angelica Maria Mora Orozco · Gloria Carolina Sandoval Beltran · Juan José Londoño Aranzazu · y 4 más

Eating disorders in childhood and adolescence are an important cause of physical and psychiatric morbidity and may lead to potentially life-threatening metabolic and neurological complications. We report the case of a male adolescent admitted to a pediatric intensive care unit following a seizure associated with severe...

Hybrid Neural and Numerical Inverse Identification of Fractional Memory and Regulatory Parameters in a Caputo Glucose Insulin Beta Cell Model

Alvaro H. Salas · Gilder Cieza Altamirano

Abstract Fractional-order models introduce memory into nonlinear dynamical systems but also turn parameter estimation into a computationally expensive inverse problem because each objective evaluation requires a history-dependent forward solve. We develop a hybrid neural–numerical framework for simultaneous identificat...

Chlorophyll-a Dynamics in a Tropical Estuary from Satellite Observations and Coupled Hydrodynamic–Biogeochemical Modeling

Víctor J. Saavedra-Mejía · Frank C. Olaya · José Manuel Zapata-Pîco · Marshall Díaz-Londoño · y 4 más

In estuarine systems, hydrodynamic processes primarily regulate the spatiotemporal variability of nutrients, and specifically chlorophyll-a (Chl-a), a key indicator of trophic status and water quality. This phenomenon appears particularly pronounced in tropical estuaries such as the Gulf of Urabá. Rivers such as the At...

Eddy-mean flow interactions in the Caribbean Sea and their modulation by current feedback to the atmosphere

Marco Larranaga · Sorayda Tanahara · Sthitapragya Ray · Eric P. Chassignet · y 8 más

The Caribbean Sea exhibits important mesoscale variability and a well-defined mean circulation, yet the role of mechanical air-sea coupling through current feedback in mesoscale variability and eddy-mean flow interactions has not been quantified.<br />Here, we analyze 24 years of Caribbean Sea dynamics using eddy-rich...

Digital access and algorithmic finance readiness among secondary students in caribbean Colombia

Evaristo Navarro Manotas · Mario Alberto De La Puente Pacheco · Angélica María Jiménez Coronado · Mario Frank Pérez Pérez · y 2 más

This article examines whether household digital access and municipal financial infrastructure are associated with readiness for algorithmic finance among secondary students in Barranquilla and Cartagena, Colombia. Using the Excel dataset provided for this study, the analysis integrates 1600 student-level observations f...

A Hybrid Memetic Algorithm for Asymmetric Vehicle Routing with Topographic Constraints: Quantifying the Orographic Gap in Mountain Urban Networks

Alejandra María Restrepo-Franco · Orlando Valencia-Rodriguez · Eliana Mirledy Toro-Ocampo · Omar Danilo Castrillón-Gómez

Classical vehicle routing models assume flat, symmetric road networks, yet mountain cities exhibit gravitational asymmetry and steep gradients that invalidate two-dimensional cost estimates and may produce mechanically infeasible routes. This study formalizes the Asymmetric Capacitated Vehicle Routing Problem with Topo...

Rasch Analysis of the Brazilian Version of the Spirit at Work Scale

Lacir José Santin Júnior · Leidy Johanna Rueda Díaz · Isabely Karoline da Silva Ribeiro · Ana Carolina Gomes Martins de Oliveira · y 2 más

Introduction: Cardiovascular diseases remain a major cause of morbidity and mortality among older adults. Preoperative nursing interventions can improve surgical outcomes by promoting functional recovery and reducing postoperative pulmonary complications. To date, evidence regarding the feasibility of an e-Nursing preo...
