Characterization of Consumer Flexibility and Its Impact on Voltage Regulation in Distribution Systems

Jesús Alexander Osorio-Lázaro · Rodolfo Garcia-Sierra · Javier Rosero-García

Modern distribution networks face growing challenges from demand growth, electrification, and distributed energy resources, complicating voltage regulation and service quality. While demand response has been proposed as a complementary tool, most existing studies assume predefined flexible loads or rely on synthetic de...

Protein–Protein Interaction-Guided Peptides Interfere with Early Zika Virus Entry-Associated Events

Carlos Andres Rodríguez-Salazar · Delia Piedad Recalde-Reyes · Santiago Linares-Jiménez · Carolina López-Cardoso · y 1 más

Zika virus (ZIKV) remains a public health concern because of its association with neurological complications and congenital disease, yet no specific antiviral therapy has been approved. Since the envelope (E) protein mediates viral attachment and early entry-associated membrane events, it represents an attractive antiv...

Quality of physicians’ responses using a conversational artificial intelligence system: a randomized vignette experiment in Latin America

Natalia Castaño-Villegas · Katherine Monsalve · María Camila Villa · Oscar Iván Quirós Gómez · y 2 más

Abstract Conversational systems based on large language models may support point-of-care evidence retrieval, but most evaluations use static benchmarks and few involve practicing physicians in low- and middle-income settings. We assessed the validity of answers produced by physicians using an evidence-traceable convers...

Série de casos e análise epidemiológica: família acometida pela doença de Fabry

José Antonio Coba Lacle · Valentina de Los Angeles Lechuga de La Hoz · Juan José Londoño Aranzazu · Gloria Carolina Sandoval Beltran · y 5 más

Introduction: Fabry disease (FD) is an X-linked lysosomal disorder caused by pathogenic variants in the GLA gene, resulting in reduced alpha-galactosidase A activity and progressive accumulation of globotriaosylceramide and globotriaosylsphingosine. The broad phenotypic heterogeneity, including within the same family,...
