Review of the Predictive Value of Biomarkers in Sepsis Mortality
Emergency Medicine International, Volume 2024, Issue 1, 2024.Sepsis is a leading cause of mortality among severely ill individuals, primarily due to its potential to induce fatal organ dysfunction. For clinicians, it is vital to have appropriate indicators, including the physiological status and personal experiences of patients with sepsis, to monitor the condition and assess prognosis.

Performance of Receiver Autonomous Integrity Monitoring (RAIM) for Maritime Operations
, 2016 The use of GNSS in the context of maritime applications has evolved during the past. The International Maritime Organization (IMO) has defined and published requirements for those applications. Comparing the requirements on the one hand specified by ICAO and on the other hand by IMO, significant differences get obvious.

Analysis of a HAPS-Aided GNSS in Urban Areas Using a RAIM Algorithm
IEEE Open Journal of the Communications Society, 2023 The global averaged civilian positioning accuracy is still at meter level for all existing Global Navigation Satellite Systems (GNSSs), and the performance is even worse in urban areas. At lower altitudes than satellites, high altitude platform stations (
