Nonlinear Modeling for the Construction of a Synthetic Index: An Approach Based on UMAP and Random Forest Applied to the Energy Performance of OECD Countries

This article proposes a hybrid method for constructing composite indices in the context of decision-making through the integration of Uniform Manifold Approximation and Projection (UMAP) and the Random Forest algorithm. Unlike Principal Component Analysis (PCA) and the Analytic H...

Assessing sediment connectivity and the beneficial use of dredged material as a nature-based solution in the Mallorquín coastal wetland

This study evaluates the hydro-sedimentological dynamics of the Mallorquín Wetland, a coastal wetland in northern Colombia affected by erosion, hydraulic disconnection, and shoreline instability. The aim was to assess sediment connectivity between the Magdalena River mouth and th...

Irisin/Integrin αVβ5/AMPK Signaling in Cardiac Fibrosis: Molecular Mechanisms and Therapeutic Potential

Cardiac fibrosis is a major pathological feature of several cardiovascular diseases and is characterized by excessive extracellular matrix deposition, leading to ventricular stiffening, impaired cardiac function, and ultimately heart failure. Despite its substantial clinical burd...

Valorization of Coffee By-Products: Cascade Pathways for Food, Materials, Energy, and Environmental Applications

Coffee production and consumption generate heterogeneous biomass and effluent streams, including pulp, husk, mucilage, parchment, silverskin, spent coffee grounds (SCGs), and processing wastewater. However, the literature on their valorization remains fragmented by feedstock and...

Energetic And Exergoeconomic Evaluation Of A Combined Cycle Power Generation System with blends Of Hydrogen and Natural Gas

Abstract Colombia's electricity sector faces increasing electricity demand and growing pressure to reduce carbon emissions. In this context, natural gas–hydrogen blends offer a promising pathway for decarbonizing gas turbine-based power generation. However, limited studies have e...

Landscape Observatories: A Systematic Review of Scientific Literature, Institutional Models and Methodological Challenges

Over the past two decades, the notion of landscape observatories has gained prominence as a strategic tool for monitoring, documenting and interpreting landscape change. These entities combine scientific research, policy advice and public engagement, aiming to bridge the gap betw...
