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 Chain Wallet or more IRSs to each user-BS pair to maximize the overall sum-rate of the network.Using passive beamforming, the
Evaluation of the 2007 WHO guideline to improve the diagnosis of tuberculosis in ambulatory HIV-positive adults.
BACKGROUND: In 2007 WHO issued a guideline to improve the diagnosis of smear-negative and extrapulmonary tuberculosis (EPTB) in HIV-positive patients.This guideline relies heavily on the acceptance of HIV-testing and availability of chest X-rays.METHODS AND FINDINGS: Cohort study of TB suspects in four tuberculosis (TB) clinics in Phnom Penh, Cambo
A tale of N cones
Abstract We study particular families of bad 3d N $$ mathcal{N} $$ = 4 quiver gauge theories, whose Higgs branches consist of many cones.We show the role of a novel brane configuration in realizing the Higgs moduli for each distinct cone.Through brane constructions, magnetic quivers, Hasse diagrams, and Hilbert series computations we study the intr
Fiberglass as a Novel Building Material: A Life Cycle Assessment of a Pilot House
Alternative building materials have the potential to reduce environmental pressure from buildings, though the use of these materials should be guided by an understanding of the embodied environmental impacts.Extensive research on embodied greenhouse gas emissions from buildings has been conducted, but other impacts are less frequently reported.Furt
