Clarifying Contradictions: Transportability in 17OHP-C Trials and Preterm Birth Outcomes Using Doubly Debiased Machine Learning Open
Following the Meis et al. trial that identified a benefit of 17-alpha-hydroxyprogesterone caproate (17OHP-C) in reducing the risk of recurrent preterm birth (PTB) (risk difference (RD) -18.6%, 95% confidence interval (CI): -28.2%, -9.2%), …

The experimental characterization of the torsional and transverse stiffnesses of a braided parachute suspension line Open
GPS-guided parachutes are used by the military to deliver supplies to personnel in the field. During descent, the suspension lines can vibrate as a result of vortex shedding and oscillating aerodynamic forces. In addition to challenging th…

Paediatric image‐guided radiation therapy: determining and evaluating appropriate kilovoltage planar exposure factors for the Varian on‐board imager Open
Introduction Kilovoltage (kV) orthogonal imaging is commonly used for image‐guided radiation therapy (IGRT) in paediatrics. Paediatrics have an increased sensitivity to radiation. Exposure factors need to be optimised so that imaging dose …
