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 Theoretical approaches of personality structure are diverse.We examine the primary emotional aspects of personality as the correspondence of two mainstream constructs: the lexically-based Big Five (BIG5) and the biologically-based Affective Neuroscience Theory (ANT) within two approaches.In the variable-centered approach (VCA), our aim is
ABSTRACT Introduction and objectives: No previous studies have established the contemporary use and outcomes of Excimer laser coronary atherectomy (ELCA) in percutaneous coronary intervention (PCI) of severely calcified coronary lesions.The aim of this study was to assess the safety, efficacy, and 1-year outcomes of ELCA in this setting.Methods: We
When the peak power exceeds many times the critical power of self-focusing, femtosecond vortex beams will break up into multiple filaments with random distribution because of the initial random noise, Radios which is adverse to the applications.By numerical simulation we demonstrate that the use of the lens array can resist the influence of initial
Molecular biology-focused knowledge graphs (KGs) are directed graphs that integrate information from heterogeneous sources of biological and biomedical data, such as ontologies and public databases.They provide a holistic view of biology, chemistry, and disease, allowing users to draw non-obvious connections between concepts through shared associat
