Semantic Communications in Multi-user Wireless Networks [PDF]
arXiv, 2022 This article investigates the exploitation of semantic communications in multi-user networks. We propose a novel heterogeneous semantic and bit multi-user framework for providing flawless, customized, and intelligent information transmission. We discuss both orthogonal multiple access (OMA) and non-orthogonal multiple access (NOMA) for the proposed ...

First Case of Cancrum Oris (Noma) in an HIV-Positive Patient in Bulgaria
Acta Medica Bulgarica, 2020 We present a case of a necrotising disease of the orofacial tissues, the so-called noma, in a female patient with AIDS in a stage of severe immune deficiency. To our knowledge, this is the first time a case like that has been reported in Bulgaria.

Partial Non-Orthogonal Multiple Access (NOMA) in Downlink Poisson Networks [PDF]
arXiv, 2021 Non-orthogonal multiple access (NOMA) allows users sharing a resource-block to efficiently reuse spectrum and improve cell sum rate $\mathcal{R}_{\rm tot}$ at the expense of increased interference. Orthogonal multiple access (OMA), on the other hand, guarantees higher coverage.
