Health Science Reports, Volume 9, Issue 7, July 2026.ABSTRACT Background and Aims Turnaround time (TAT) is a key metric of laboratory performance. However, delays occurring outside the intra‐laboratory phases are often overlooked. This study aimed to assess intra‐laboratory TAT and patients' perceptions of laboratory service quality in a public tertiary hospital in Pakistan.

Evaluating the Prediction of Wind Power Ramping Events in the Belgian Offshore Zone
Meteorological Applications, Volume 33, Issue 4, July/August 2026.This work proposes a flexible verification framework to assess wind power ramp forecasts more comprehensively than standard metrics. Applied to the Belgian Offshore Zone, it demonstrates the effectiveness of Wind‐Farm‐Parameterization and machine learning models and indicates a strong link between severe precipitation and predictable ramp events ...

Physical Layer Security Using Two-Path Successive Relaying
Sensors, 2016 Relaying is one of the useful techniques to enhance wireless physical-layer security. Existing literature shows that employing full-duplex relay instead of conventional half-duplex relay improves secrecy capacity and secrecy outage probability, but this ...

Outage probability of selective decode and forward relaying with secrecy constraints
CoRR, 2011 We study the outage probability of opportunistic relay selection in decode-and-forward relaying with secrecy constraints. We derive the closed-form expression for the outage probability. Based on the analytical result, the asymptotic performance is then investigated. The accuracy of our performance analysis is verified by the simulation results.
