Recent Hydrogeomorphological Changes and Their Impacts on Hydrodynamics and Water Quality in the Amazon Basin Estuarine Region—Amapá/Brazil

Over the past fifteen years, the lower Araguari River drainage system has undergone profound hydrogeological reconfiguration, disconnecting its mouth from the Atlantic Ocean and forming two new channels. This study experimentally quantified the impacts of these changes on hydrody...

Reproducible Multicriteria Reanalysis of a Four-Criterion UASB-Oriented Source Matrix for WWTP Biogas-Recovery Prioritization

This study performs a computationally reproducible multicriteria reanalysis of a four-criterion, UASB-oriented source matrix reported in a 2015 MSc dissertation. Two author-generated numerical scenarios, each containing six WWTP alternatives, are treated as constructed cases rath...

A systematic review and individual patient data meta-analysis to determine the effect of primaquine dose on efficacy, tolerability and safety in uncomplicated Plasmodium vivax malaria in Latin America

Background Primaquine is widely used to prevent relapses of Plasmodium vivax malaria, but the optimal dose in Latin America is unknown. We undertook a systematic review and individual patient data meta-analysis to investigate the efficacy, tolerability and safety of different pri...

The top 100 cited papers in AI and Healthcare: trends, collaborations, and key contributions

Abstract Purpose This study performed a bibliometric analysis of the top 100 most cited papers on artificial intelligence (AI) and its applications in health and medicine. Data was retrieved from the Scopus database in December 2024, focusing on papers published between 2001 and...

Longitudinal Changes in Work-Related Pleasure, Suffering, and Harm Among Healthcare Workers During the COVID-19 Pandemic

Healthcare workers experienced substantial psychosocial challenges during the coronavirus disease 2019 (COVID-19) pandemic, yet longitudinal evidence on changes in work-related pleasure, suffering, and harm remains limited. This study investigated longitudinal changes in psychoso...

Estimation of Nodal Voltage Angles in Electrical Power Systems Using Artificial Neural Networks and Sensitivity Analysis of Input Variables

The estimation of nodal voltage angles is essential for the efficient and secure operation of electrical power systems. Traditionally, this estimation depends on the prior solution of the power flow problem, a procedure that may become computationally expensive in studies involvi...
