Valorisation of Vegetal Biomass Residues in the Development of Sustainable Composites: An Alternative for Biodegradable Packaging

Rodrigo Ortega-Toro · Candelaria Tejada-Tovar · Nicole Yances-Guette · Joaquín Hernández-Fernández · y 1 más

This study investigated the development of biopolymer films from bitter cassava starch (Manihot esculenta) and coconut mesocarp cellulose as a promising alternative for biodegradable packaging. The biopolymer film was prepared using the casting method, with glycerol as a plasticiser and Tween 80 as an emulsifier. Diffe...

Clasificación del déficit hídrico en plantas de arándano mediante termografía de bajo costo e inteligencia artificial

Jaime Andrade Ramirez · Gina Maribel Valenzuela · Gabriel Martinez Roldan · Juan Fuentes Rojas

Introduction. Water deficit stress is a limiting factor in blueberry (Vaccinium corymbosum L. ‘Biloxi’) production. Infrared thermography detects this stress, but its high cost limits its adoption. Objective. To develop and validate a low-cost system, based on low-resolution thermography and a multilayer perceptron arc...

Artificial Intelligence-Assisted Systematic Literature Reviews in Metabolic Phenotyping: A Methodological Framework and Validation Study

Maartje Cox · Javier Osorio Mosquera · Shaimaa Khandaker · Samuele Sala · y 5 más

Abstract Systematic literature reviews are widely acknowledged to be at the top of most evidence hierarchies but are very time-consuming and labour-intensive. The advent of artificial intelligence (AI) offers possibilities to accelerate the review process. We propose a systematic literature review protocol that incorpo...

Cross-interface persistent memory for large language model-assisted radiology research workflows: a Claude-based proof-of-concept technical development

Miguel, Angarita · Lina M, Acosta Buitrago · Juan Manuel, Pérez

Background and purpose Large language model (LLM)-assisted radiology research and tool-development work is hampered by a practical form of memory loss we term cross-interface fragmentation: project context built in a web-based conversational interface is not available in a local coding-agent environment, and neither en...

Molecular Energetics and Non-Isothermal Kinetics of Polystyrene Degradation: An Integrated Oligomeric DFT–TGA Study

Joaquín Hernández-Fernández · Rafael González-Cuello · Rodrigo Ortega-Toro

Polystyrene (PS) thermal degradation involves localized molecular bond-cleavage events that are not directly equivalent to the apparent kinetic parameters obtained from bulk thermal analysis. In this study, a finite hydrogen-terminated PS oligomeric model was examined using density functional theory at the M06-2X/LANL2...

Amount and Burden of Brain Tissue Hypoxia to Determine Clinical Efficacy of Secondary Decompressive Craniectomy After Moderate/Severe Traumatic Brain Injury

Santiago Lubillo · Patricia Lopez · Dacil Parrilla · Jose Blanco · y 4 más

BACKGROUND AND OBJECTIVES: Optimal timing and patient selection for secondary decompressive craniectomy (DC) in traumatic brain injury (TBI) with refractory intracranial hypertension remain uncertain. Surgical indication is primarily based on intracranial pressure (ICP), without routinely incorporating brain tissue oxy...
