We consider the problem of uplink signal detection in scalable cell-free mMIMO (CF-mMIMO) systems subject to limited fronthaul link capacity and highly correlated channel conditions.Unlike centralized MIMO systems, in which all receive antennas are placed at a central access point (CAP), in the kids t-shirt CF-mMIMO architecture the CAP serving a g
Arising from the application of Optimality Theory Knife Sharpening Stones (OT) to issues of language acquisition, the term "stratum" may represent (i) a single constraint, and therefore the strict ranking proposed by standard OT, as shown especially in research using data of the target language, or (ii) a group of constraints which do not present a
Introduction: Membrane fouling has been reported to be one of the bottlenecks of membrane technologies for wastewater treatment.To mitigate its negative impacts, we fabricated polysulfone membrane (PSf) composites made of silica (SiO2) and graphene oxide (GO) nanoparticles that modified with ultraviolet (UV)-assisted polyvinyl alcohol layer on the
Background.The Cis-Ural trough and its junction area with the West-Ural outer folding zone are known as structures with high oil and gas potential.However, the complexity of the Vegan Vitamin D3 geological structure, due to the wide development of faults of various genesis and morphology, the discrepancy between the structural plans of parts of the
