Genome-resolved metagenomics reveals a high diversity of novel, non-methanogenic lineages in an Andean páramo wetland

Daniela Betancurt-Anzola · Joan Vanegas · Sophie K. Jurgensen · Kelly C. Wrighton · y 2 más

Abstract Wetlands are the largest natural source of atmospheric methane, yet tropical high-altitude wetlands remain underrepresented in global climate frameworks. Here, we investigated soil metagenomes from the páramo ecosystem in Chingaza National Natural Park (Colombia) across three vegetation-defined ecosites. Micro...

Antimicrobial Efficacy of Smear Clear in the Elimination of Enterococcus faecalis. An In Vitro Study

Javier Alvear-Pérez · Stella Pupo-Marrugo · José Florez-Ariza · Liz Guerrero-Rodríguez · y 2 más

Microorganisms are fundamental etiological factors in pulpal and periapical diseases. Enterococcus faecalis, a Gram-positive facultative anaerobic coccus, can penetrate dentinal tubules and survive chemical-mechanical instrumentation. Endodontic success requires effective irrigation to reach areas inaccessible to instr...

Síntesis de un mecanismo de rodilla para prótesis transfemoral

Juan Camilo Salazar-Franco · Luz Adriana Mejía-Calderón

Este artículo presenta el diseño y validación computacional de una prótesis transfemoral con rodilla policéntrica, usando síntesis cinemática y dinámica de sistemas multicuerpo. Se sintetizaron dos mecanismos (cuatro barras y Stephenson) para reproducir la trayectoria fisiológica del centro instantáneo de rotación (CIR...

Threshold-Driven Integrated Management of the Coffee Berry Borer: Insights from Bifurcation Analysis

Carlos Andrés Trujillo-Salazar · Gerard Olivar-Tost · Deissy Milena Sotelo-Castelblanco

The coffee berry borer (Hypothenemus hampei) is the primary pest of coffee crops worldwide. Sustainable management strategies increasingly rely on the integration of biological control and interventions activated by population thresholds. In this work, a comparative framework based on dynamical systems is presented, in...

Hacia una adaptación de la responsabilidad civil a la inteligencia artificial y su proyección en Colombia

Olenka Deniss Woolcott Oyague · Karen Isabel Cabrera Peña · Daniela Navarro Reyes

La inteligencia artificial (IA) plantea riesgos inéditos que desbordan los marcos tradicionales de responsabilidad civil. Este estudio, con enfoque dogmático, examina la suficiencia del régimen colombiano de productos defectuosos (Ley 1480 de 2011) frente a la IA y lo contrasta con la Directiva (UE) 2024/2853. Se advie...

Sensitivity Analysis of the Electric Vehicle Charging Station Feasibility Considering Renewable Energy Generation and Microscopic Traffic Simulations

Fredy Alexis Dulce · Jackeline Murillo-Hoyos · Eduardo Francisco Caicedo-Bravo

This study analyzes the economic viability of electric vehicle charging stations (EVCSs) in medium-sized cities with low electric vehicle (EV) adoption. Based on EVCS usage patterns from both Europe and the USA, and validating EV energy consumption with a microscopic model of roads and traffic through the Eclipse SUMO...

Neutrophil‐to‐Lymphocyte Ratio as a Predictor of Cardiovascular Events in Psoriatic Disease: A Retrospective Cohort Study

Mauro Martini · Luciano Logiudice · Luis D. Mazzuoccolo · Nicolas Alvarado · y 6 más

Objective The aim of this study was to evaluate the neutrophil‐to‐lymphocyte ratio (NLR) as an independent predictor of major adverse cardiovascular events (MACEs) and all‐cause mortality in patients with psoriasis (PsO) or psoriatic arthritis (PsA). Methods We conducted a retrospective cohort study of 967 patients (82...
