PRIMBIT toward Tube(Fib): Algebraic Framework, Prism Realization, and a Falsifiable Certification Program

This preprint develops a falsifiable mathematical and computational route from PRIMBIT toward a finite realization of the Fibonacci tube algebra. The abstract target is Tube(Fib) ≅ C³ ⊕ M₂(C). An explicit triangular-prism annulus is specified, with a raw Hilbert space of dimensio...

Endoscopic‐guided platelet‐rich plasma for refractory oesophageal strictures in children: A single‐arm cohort study

OBJECTIVES: Oesophageal stenosis is a serious sequel of caustic ingestion, especially refractory caustic oesophageal strictures (COS) with a high risk of adverse events and variable response to treatments such as dilations, infiltration of substances and stent placement. Platelet...

Clinical and Economic Burden of Complicated Pneumonia and Invasive Disease due to Streptococcus pneumoniae Serotype 19A in an Ecuadorian Pediatric Reference Hospital

Serotype 19A has emerged as an important cause of pneumococcal disease following the introduction of the 10-valent pneumococcal conjugate vaccine (PCV10). In this retrospective study of children hospitalized with culture-confirmed invasive pneumococcal disease at an Ecuadorian pe...
