In this paper, we investigate the assignment of intelligent reflecting surfaces (IRSs) to user-base station (BS) pairs in a multi-IRS-assisted wireless communication network.Our objective is to optimize the allocation of one or more IRSs to each user-BS pair to maximize the overall sum-rate of the network.Using passive beamforming, the transmitted

Abstract Tarsal navicular PERFORMANCE fractures, as well as other midfoot injuries, are rare, and can result in severe impairment if not properly treated.Parkour, a modern sport, is gaining popularity among young individuals in urban areas, and is prone to result in high-energy trauma, which is scarcely described in the literature.The following is

Aiming at the vibrations of the multistage gear transmission system aroused by the gear meshing excitation, a novel active vibration control structure with built-in piezoelectric actuators (PZT) was established.The active control forces generated by the MAGNESIUM PZT were transmitted to the shafts through the additional supporting bearings.In addit

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterized by the deterioration of motor neurons.However, this complex disease extends beyond the boundaries of the central nervous system, with metabolic alterations being ORG ORIGINAL UNSALTED observed at the systemic and cellular level.While the number of studies that assess
