Restoration of an Upper Lip Affected by Necrotizing Ulcerative Stomatitis Using Bilateral Cheek Advancement with a Crescentic Perialar Excision [PDF]
Archives of Aesthetic Plastic Surgery, 2018 Necrotizing ulcerative stomatitis (NUS) refers to ulceration of the oral mucosa that precedes rapid orofacial soft- and hard-tissue destruction. NUS on the upper lip is considered a reconstructive challenge because of the functional importance and ...

Dynamic User Clustering and Power Allocation for Uplink and Downlink Non-Orthogonal Multiple Access (NOMA) Systems [PDF]
IEEE Access, 2016 Non-orthogonal multiple access (NOMA) has recently been considered as a key enabling technique for 5G cellular systems. In NOMA, by exploiting the channel gain differences, multiple users are multiplexed into transmission power domain and then non ...

Tropical Medicine and Health, 2022 AbstractNoma is a bacterial, non-communicable, grossly destructive and disfiguring necrotising oro-facial disease. It is rare, but occurs most commonly in chronically malnourished children with other debilitating illnesses, in remote, poverty-stricken communities, mainly in sub-Saharan Africa, and much more rarely in central Latin America and in parts ...
