Article Synopsis
- The article presents the Enhanced Gorilla Troops Algorithm (EGTA) as a new method for optimizing the placement of Thyristor Controlled Series Capacitors (TCSC) in power grids, inspired by the behavior of gorilla groups.
- EGTA includes features that enable better exploration and exploitation through techniques like the Tangent Flight Operator and Fitness-based Crossover Strategy, and its effectiveness is tested against other optimization methods using benchmark problems.
- Results from simulations on IEEE power grids demonstrate that EGTA significantly reduces power losses compared to the original Gorilla Troops Algorithm, achieving notable improvements in TCSC allocation across different system configurations.
Introduction: In the past, fertility concerns have predominantly revolved around the effect of a woman's age on the quality of her eggs and the success of her pregnancy. While men generally retain their ability to father children throughout their lives, there is evidence suggesting a decline in natural conception rates as paternal age increases. A growing body of research indicates a potential link between advanced paternal age (APA) and various adverse outcomes, including changes in sperm genetics, reduced conception rates, higher rates of miscarriage, lower live birth rates, and even long-term health consequences in offspring.

- - The study investigates the prevalence and risk factors of gastrointestinal bleeding in emergency department patients over a 10-year period in Riyadh, Saudi Arabia.
- - Out of 760 patients, the average age was 62.7 years, with higher occurrences of bleeding found in males and common comorbidities including hypertension and diabetes.
- - Results showed that lower gastrointestinal bleeding was more prevalent than upper gastrointestinal bleeding, with specific causes identified for both, such as hemorrhoids and esophageal varices.
UAV-Based Secure Data Communication: Multilevel Authentication Perspective.
Sensors (Basel)
February 2024
An Internet of Things (IoT) system for managing and coordinating unmanned aerial vehicles (UAVs) has revolutionized the industrial sector. The largest issue with the design of the Internet of UAVs (IoUAV) is security. Conspicuously, the novel contribution of the proposed work is to develop a layered authentication approach to facilitate safe IoUAV communication.

Methods: This retrospective study, performed in a single center in Saudi Arabia between August 2017 and July 2022, we enrolled 140 consecutive patients with HCV who received generic SOF and branded DCV. The primary outcome was sustained virologic response at week 12 (SVR12).
