Clasificación morfométrica de domos lunares mediante agrupamiento no supervisado y descriptores ortogonales

Laura Daniela Jiménez-Prada · Javier Eduardo Suárez-Valencia

Los domos lunares registran señales de procesos volcánicos y térmicos superficiales y subsuperficiales, por lo que una clasificación morfométrica bien fundada facilita la interpretación de su génesis y aporta claves sobre la evolución térmica de la corteza lunar. En este estudio proponemos una nueva clasificación basad...

Use of aluminum sulfate in continuous bladder irrigation for the treatment of hematuria: a case series

Dadier Antonio Arroyo Monterroza · Dina Rodríguez Rodríguez · Maria Suarez Sanchez · Daniel Ospina Herrera · y 1 más

Introduction: hematuria, defined as the presence of blood in urine, poses a therapeutic challenge when refractory to conventional treatments. Its prevalence ranges from 2.5% to 20% in adults, with 80% of cases being of urological origin. Initial management strategies include hydration, three-way Foley catheter insertio...

Unpacking innovation in technology-based entrepreneurship: the role of venture capital, networks and research capacity in an emerging economy

Liney Manjarres-Henriquez · Yazmin Jimenez-Celin · Paola Amar-Sepúlveda

Purpose This study aims to investigate the determinants of innovation performance in technology-based firms (TBFs) located in regions with low research and development (R&D) intensity, using Colombia as an empirical case. It examines how internal capabilities and external ecosystem variables, such as venture capital (V...

Transformaciones Socioecológicas del Complejo de Humedales el Candil – Norte del Departamento del Cauca (1940-2020)

Luis Felipe Salazar Arcila · Aceneth Perafán Cabrera

The development of various human activities has impacted the biodiversity and environmental services of several inland aquatic ecosystems, especially wetlands. In particular, in the Upper Cauca River Basin, Colombia, processes closely associated with agricultural expansion linked to the large-scale production of sugarc...

Solitary and Cnoidal Structures in Plasmas Described by a Residual-Controlled Time-Fractional Gardner Equation

Alvaro H. Salas · Weaam Alhejaili · Samir A. El-Tantawy

The present work is devoted to the analysis of a time-fractional Gardner equation arising in the modeling of nonlinear plasma waves in media endowed with memory and anomalous transport effects. Building on a physically motivated soliton profile, we construct a finite-time fractional ansatz in which the integer-order ti...
