On the need to account for soil erosion rates in water quality indices for tropical Rivers: Insights from Cesar River, Colombia

A large body of research suggests that soil erosion in developing countries is reaching critical rates and that its offsite effects (e.g., increased sediment concentration in water bodies) could be amplified by global warming. In most cases, Water Quality Indices (WQI) do not dif...

Regional Hydroclimatic Sensitivity of Monthly Precipitation Anomalies to ENSO in the Colombian Andes and Orinoquia

El Niño–Southern Oscillation (ENSO) modulates tropical South American rainfall, but its Colombian expression is filtered by terrain, rainfall regime, moisture pathways, and atmospheric state. We quantify ENSO-related sensitivity of standardized precipitation anomalies in the Colo...

Effect of External Electric Fields on Defective AlN/GrapheneHeterobilayer: A First-Principles Study

Abstract Graphene-based van der Waals heterobilayers play a fundamental role in the fabrication of optoelectronic, micro- and nanoelectronic, and spintronic devices. In this paper, four new stackings for the (4 × 4)-AlN/(5 × 5)-graphene denominated as AA, AA′, A′B, and A′B′ are i...
