Joint power control and user grouping mechanism for efficient uplink non‐orthogonal multiple access‐based 5G communication: Utilising the Lèvy‐flight firefly algorithm

IET Networks, EarlyView., 2023
We utilise a metaheuristic optimisation method, inspired by nature, called the Lévy‐flight firefly algorithm (LFA), to tackle the power regulation and user grouping in the NOMA systems. Abstract The non‐orthogonal multiple access strategies have shown promise to boost fifth generation and sixth generation wireless networks' spectral efficiency and ...

Lower synovial leucocyte count and polymorphonuclear percentage reliably differentiate periprosthetic joint infection after unicompartmental knee arthroplasty

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose This study aimed to determine diagnostic thresholds for synovial fluid leucocyte count and polymorphonuclear (PMN) percentage to identify the diagnosis periprosthetic joint infection (PJI) in patients with failed unicompartmental knee arthroplasties (UKAs).

Is Ankyloglossia Correlated With Pediatric Sleep Disordered Breathing? A Systematic Review

The Laryngoscope, EarlyView.
An increasing breadth of conditions and symptoms are being ascribed to ankyloglossia. As diagnosis of ankyloglossia and frequency of frenotomy exponential increase, it is important to have an understanding of the associated evidence. This systematic review summarizes the evidence for ankyloglossia's association with sleep disordered breathing in ...

Faraday–Ramsey Rotation in Ultrathin Alkali Vapor Cells as an Analogy to Atomic‐Beam Systems

Laser &Photonics Reviews, EarlyView.
This work demonstrates that ultrathin rubidium vapor cells can emulate atomic‐beam behavior through geometry‐dependent velocity filtering. Employing a spatially separated pump–probe scheme and Faraday–Ramsey rotation, the study reveals coherent atomic dynamics without buffer gas or anti‐relaxation coatings. This approach offers a compact pathway toward

An Optimized Staining Method for Visualization of Thermally Denatured Dermal Collagen

Lasers in Surgery and Medicine, EarlyView.
ABSTRACT Background and Objectives Accurate visualization of thermal damage zone (TDZ) in the dermis is critical for energy‐based device (EBD) and burn research. While nitroblue tetrazolium chloride (NBTC) staining and birefringence imaging are commonly used, both rely on detecting loss‐of‐signal, thereby only inferring TDZ indirectly.
