How data velocity changes decisions: The role of information access speed

Miguel Espinosa · Hyunjin Kim · Sergio Prada

Abstract Research Summary Recent technological advancements have enabled more data‐driven decision‐making across firms. While prior literature highlights the value of using more data, there is less insight on the impact of information speed, particularly how quickly decision‐makers can access it. We study how faster in...

Comparative evaluation of laboratory and field compaction methods on the performance of pervious concrete

K. D. B. De S. Risson · L. G. C. Portugal · G. C. Réus · M. H. F. De Medeiros · y 2 más

This study evaluates the influence of casting and compaction procedures on the mechanical and hydraulic performance of pervious concrete (PC) under laboratory and field conditions. Twelve laboratory procedures were assessed by combining three compaction methods (tamping rod, Proctor hammer, and Proctor hammer with a ci...

Sustainable Carbon Dioxide Valorization Through Catalytic and Non-Catalytic Routes: A DFT Study

Joaquín Alejandro Hernández Fernández · Juan Lopez-Martinez · Jose Alfonso Prieto Palomo

This study presents a comprehensive thermodynamic evaluation of several CO2 conversion pathways, both non-catalytic and catalyst-assisted, using density functional theory (DFT) calculations in Gaussian 16 (B3LYP/6-311++G(d,p)). In the non-catalyzed section, three key routes are examined: hydrogenation (CO2 + H2 → CO +...

An Analytical Model for Low-Frequency Vibration Energy Harvesting in a Cantilever Beam with a Piezoelectric Patch: Development and Qualification Using Experimental Data

Jorge Enrique Herrera Arroyave · Diego Fernando Arias Mateus · Milton Humberto Medina Barreto · Jorge Alfredo Ferrer Pérez · y 1 más

Vibration-based piezoelectric energy harvesting provides a potential power source for low-consumption devices; however, its prediction requires a consistent representation of localized structural properties and experimentally identified modal behavior. This study presents the structural and modal qualification of an an...

Traumatic brain injury outcomes across human development index strata in 29 countries

Joseph G. Nugent · Hao Tan · Brittany Stedelin · Caleb S. Nerison · y 196 más

Prior large-scale multicountry studies of traumatic brain injury (TBI) have either focused on surgically managed patients across development settings or characterized the full case-mix in predominantly high-income regions, leaving operative and nonoperative TBI across the human development spectrum incompletely defined...

Este artigo analisa os efeitos das políticas de inclusão educacional no sucesso e na permanência escolar de estudantes com Necessidades Educativas Específicas (NEE) na rede pública do Espírito Santo, no período de 2020 a 2024. A pesquisa, de abordagem quantitativa com complementação qualitativa, baseia-se em dados ofic...

Imputation of Thermal and Magnetic Variables in Shape-Memory Alloys (Ni–Mn–Ga) Using Machine Learning Techniques with Cross-Validation and Multi Seed

Juan C. Buitrago Diaz · Edwin G. Castro Rodas · Carolina Ortega-Portilla · Juan E. Bedoya-Rodriguez · y 3 más

Magnetic shape memory alloys based on the Ni–Mn–Ga system are of strategic interest for aerospace and robotics applications due to their ability to respond to both thermal and magnetic stimuli. However, the NASA Shape Memory Materials Database a key resource for the community exhibits significant gaps in functional par...

Place‐based environmental distress and psychosocial profiles of adolescent mental health in transformed Colombian territories

Felipe Agudelo‐Hernández · Diana Carolina Aguirre‐Flórez

Abstract Objectives This study aimed to identify psychosocial profiles among Colombian adolescents living in environmentally transformed territories and to examine whether solastalgia was associated with profile membership and territorial variation. Design A cross‐sectional, person‐centred analytical study was conducte...
