Clinical, functional, and radiological profile of fibrotic interstitial lung disease at high altitude: a registry-based cohort from two referral centres in Bogotá, Colombia (2,600 metres above sea level)

Ingrid Ruiz-Ordoñez · Dolfus Santiago Romero · Leonardo Galindo · Carlos Andrés Celis-Preciado · y 1 más

Abstract Interstitial lung diseases (ILD) are a heterogeneous group of conditions characterised by variable degrees of inflammation and pulmonary fibrosis. Data from high-altitude settings, where hypobaric hypoxia may modulate disease expression and functional thresholds, remain scarce. We describe the demographic, cli...

The Paradox of Inclusion: Modeling Systemic Dynamics of the Gender Finance Gap in Entrepreneurial Ecosystems

Nicolás Fuentes · Jana Schmutzler · Gustavo Carreón-Vázquez

Gender inequality in venture capital remains a persistent systemic issue shaped by interacting socio-institutional, network, and entrepreneurial ecosystem (EE) dynamics. This study examines how targeted inclusion interventions interact with structural and network-level dynamics to shape the gender finance gap. Conceptu...

Technical Feasibility Analysis of DC Microgrids in a Non-Interconnected Area

Iván Felipe Muñoz Sarria · Maximiliano Bueno López

Context: In recent times, access to electricity in non-interconnected areas has been a constant challenge. Therefore, this article evaluates the technical feasibility of implementing direct-current (DC) microgrids in these areas, focusing on food conservation. Our evaluation focuses on the region of Chacón Playa (Timbi...
