We derive the couplings of the 3-form supermultiplet to the general supergravity-matter-Yang-Mills system. Based on the methods of superspace geometry, we identify component fields, establish their supergravity transformations and construct invariant component field actions. Two specific applications are adressed: the appearance of fundamental 3-forms in the context of strong-weak duality and t...

We discuss nominalizations in Portuguese formed by the suffix -ura. We have done a corpus-based description of the behavior of these nominals and proposed a type ontology to categorize them. In order to offer a rich description, we also tested all words formed by -ura in co-predication contexts to check if their types could be co-predicated. Although our main goal was to produce a corpus-based ...

In this paper, we propose a novel fully Bayesian approach for the massive multiple-input multiple-output (MIMO) unsourced random access (URA). The payload of each user device is coded by sparse regression codes (SPARCs) without redundant parity bits. A model established to capture probabilistic characteristics overall system. Particularly, adopt core idea model-based learning establish flexible...

Half-power beamwidth (HPBW) is a key parameter to measure the performance of antenna array and newly proposed intelligent reflecting surface (IRS) systems. In this letter, we first establish system model for IRS in uniform linear (ULA) rectangular (URA) configurations, then HPBW both cases are derived under far-field condition without considering channel path-loss fading. We find that ULA URA e...
