An Efficient Implementation of Fixed Failure-Rate Ratio Test for GNSS Ambiguity Resolution
Sensors, 2016 Ambiguity Resolution (AR) plays a vital role in precise GNSS positioning. Correctly-fixed integer ambiguities can significantly improve the positioning solution, while incorrectly-fixed integer ambiguities can bring large positioning errors and ...

Heart rate and blood pressure monitoring in heart failure. [PDF]
, 2019 It has been long known that incessant tachycardia and severe hypertension can cause heart failure (HF). In recent years, it has also been recognized that more modest elevations in either heart rate (HR) or blood pressure (BP), if sustained, can be a risk

On the Rate of Crustal Failures in Young Magnetars [PDF]
The Astrophysical Journal Letters, 2020 Abstract The activity of magnetars is powered by their intense and dynamic magnetic fields and has been proposed as the trigger to extragalactic fast radio bursts. Here we estimate the frequency of crustal failures in young magnetars, by computing the magnetic stresses in detailed magnetothermal simulations including Hall drift and ohmic
