Cerebrospinal fluid cytochemical parameters as predictors of FilmArray Meningitis/Encephalitis panel positivity: a diagnostic stewardship approach in immunocompetent and immunocompromised patients

Infectious meningoencephalitis requires prompt diagnosis to reduce mortality and neurological sequelae. The FilmArray Meningitis/Encephalitis (FAME) panel has improved pathogen detection, but its indiscriminate use raises cost-effectiveness concerns. Because FAME is itself an imp...

Hiperuniverse

This volume develops the Hiperuniverse hypothesis as an ontology for a singleself-contained physical whole. It treats reality as a changing relationalconfiguration whose operative distinctions appear as events and retainedrecords. Space and time are therefore to be recovered rath...

Estimating Drought Hydrographs for Different Return Periods Using Hydrological Records: Regulated and Natural Flow Regimes

This study proposes a probabilistic methodology to estimate drought hydrographs from observed discharge data recorded at a river gauging station under natural hydrological conditions and under reservoir operation for hydropower generation, with data fitted to statistical probabil...

Elastic Water Column Modelling of an Undulating Pipeline Profile with Entrapped Air

Emptying pressurised pipelines with undulating profiles can generate subatmospheric pressure conditions that compromise structural integrity, particularly when no air admission valve is considered. One-dimensional models for this transient event have so far relied on the Rigid Wa...

Subnational Heterogeneity in RSV Seasonality in Tropical Colombia, 2022–2024

Abstract Background RSV transmission in tropical settings is often assumed to occur year-round, and preventive strategies are frequently recommended accordingly. However, sub-national variation in epidemic timing remains incompletely characterized. Granular local surveillance dat...

Technology life cycle: Greenhouses

This article provides an analysis of the technological life cycle (TLC) of greenhouses, an essential element of modern agriculture that has evolved from basic crop-protection structures into highly sophisticated systems integrating construction, energy, and digital innovations. T...

Integrated assessment of coastal socio-environmental vulnerability in the southwestern Colombian Caribbean

Abstract Coastal vulnerability is a critical determinant of risk in littoral systems, particularly in regions where seasonal environmental forcing intersects with persistent socioeconomic fragility. This study assesses the integrated socioeconomic and environmental vulnerability...
