Rate Adaption for Secure HARQ-CC System with Multiple Eavesdroppers

open access: yesEntropy, 2020
In this paper, we studied the secure transmission of a hybrid automatic repeat request with chase combining (HARQ-CC) system, under the existence of multiple eavesdroppers and limited latency.

Turnaround Time and Patients' Perceptions of Clinical Laboratory Services at a Tertiary Hospital in Pakistan: A Cross‐Sectional Study

open access: yesHealth 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

open access: yesMeteorological 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 ...

Forgoing Nuclear: Nuclear Power Plant Closures and Carbon Emissions in the United States

open access: yesSouthern Economic Journal, Volume 93, Issue 1, Page 252-273, July 2026.
ABSTRACT This paper examines the effect of nuclear power plant decommissioning on electricity generation and carbon emissions in the United States. Using data on nuclear reactor closures in the United States between 1993 and 2022 and data on state‐level carbon emissions and electricity generation from the Energy Information Administration (EIA), this ...

Secrecy outage probability of two-path successive relaying in physical layer security

open access: yes, 2016
Relaying is a promising technique to improve wireless physical-layer security. Existing literature shows that a full-duplex relay can further improve the secrecy capacity and secrecy outage probability compared to conventional half-duplex relay, but this

Defense Algorithm Based on Reinforcement Learning and Digital Twin for Distribution Protection Devices Adversarial Samples

open access: yesEngineering Reports, Volume 8, Issue 6, June 2026.
Power system protection devices are vulnerable to adversarial samples. We propose a digital twin and reinforcement learning framework. It trains a virtual model within safe operational boundaries, reducing the false operation rate to below 3.5%. The model's inference delay is under 10 ms, meeting real‐time protection requirements.

Physical Layer Security Using Two-Path Successive Relaying

open access: yesSensors, 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 ...
