Eficiencia en la gestión del sector minero-energético en Latinoamérica: revisión sistemática

Manfred Jaramillo Bonilla · Ellie Anne López Barrera · Andrés Mauricio Perafán

La eficiencia energética es estratégica para la competitividad y sostenibilidad del sector minero-energético latinoamericano, pero la evidencia disponible está fragmentada y falta una lectura regional integrada. Este artículo tuvo como objetivo analizar patrones regionales, estrategias predominantes y brechas comunes e...

Differential responses of intertidal crab assemblages to rainfall intensity and dominant Mangrove species in Eastern Pacific forests

Angela Inés Guzmán-Alvis · Luz Ángela López de Mesa · Dalliam Felipe Chacón-Currea · Adriana Martínez-Arias · y 4 más

Abstract Mangrove sediments sequester large amounts of carbon, yet local controls on sediment organic carbon (SOC) remain uncertain. We tested how rainfall variability and dominant mangrove species relate to sediment physicochemical conditions and intertidal crab assemblages in five Eastern Pacific mangrove forests (Co...

Exact Nonlinear Attitude Dynamics of Gravity-Gradient Spacecraft: Elliptic Libration Orbits, Separatrices and Energy-Based Stability Thresholds

Alvaro H. Salas

Abstract Gravity-gradient stabilization is one of the simplest passive attitude concepts for Earth-pointing spacecraft, yet its large-angle dynamics are often assessed with small-angle or low-order polynomial models that do not preserve the global phase-space structure. This work develops a compact exact description of...

A mechanistic statistical model of dengue dynamics in an endemic region

Nicolás Luna-Martínez · Erika Ximena Cruz-Rodríguez · Edgar Andrés Bernal-Castro

Abstract Background Dengue is a major public health challenge, and predictive models are crucial for early warning systems. However, many current modeling practices rely exclusively on climatic factors or employ complex algorithms that lack the interpretability needed for informed public health decision-making. To addr...

Technology-Oriented Wind Farm Configuration Selection Using an RFR-Based Turbine Power-Output Surrogate Model: A National-Scale Assessment for Brazil

José Pericles Freire · Douglas Silva de Oliveira · Lihki Rubio · Jin Yang · y 1 más

This work presents a framework for national-scale onshore wind farm screening in Brazil based on turbine technology. The approach integrates ERA5 hourly wind fields, turbine technical specifications, a Random Forest Regression (RFR)-based turbine power-output surrogate model, and GIS-based spatial exclusion analysis. T...

Territorial deprivation and remotely mapped building damage after the 2026 Colombia earthquake: A multi-city analysis

Gelys Mestre Carrillo · María Isabel Castro-Rebolledo · Lucia C. Lozano

Abstract. Earthquake impacts reflect not only the spatial distribution of seismic shaking but also the characteristics of the territories in which exposed buildings are located. This study examined the association between territorial deprivation and remotely mapped building damage following the 10 August 2026 Colombia...

When the evolved social mind goes online: How digital ecologies recalibrate mentalizing and social bonding

Mitigating Urban Grid Stress via Grid-Aware Deployment of PV-BESS Charging Hubs Using a Spatial MCTS Approach Applied to Bogotá

Diego Julián Rodriguez Patarroyo · Jaime Francisco Pantoja Benavides · Frank Nixon Giraldo Ramos

This research presents an integrated techno-energetic framework to decouple electric vehicle (EV) fleet growth from urban grid instability, using Bogotá, Colombia, as a case study. As emerging megacities confront rising charging demands, conventional reactive grid reinforcements are becoming technically and economicall...

CANABIDIOL NO TRATAMENTO DA FIBROMIALGIA: EVIDÊNCIAS SOBRE EFICÁCIA, SEGURANÇA E CONTROLE DOS SINTOMAS

Bruna Angélica Strunkis · Thomaz Funari Neto · João Paulo Junqueira Cervantes Santos · Peterson Rose Pereira · y 5 más

A fibromialgia é uma síndrome de dor crônica caracterizada por dor musculoesquelética generalizada, fadiga, alterações do sono, dificuldades cognitivas e importante comprometimento da qualidade de vida. A resposta incompleta de parte dos pacientes às estratégias terapêuticas convencionais tem estimulado o interesse por...
