The International Journal of Health Planning and Management, EarlyView.ABSTRACT The unquenched thirst for emigration in Nigeria‐ and the increasing cost of migrating to the West‐has been established in the literature. Professionals, such as healthcare workers (HCWs), are poorly paid in Nigeria, making many seek better employment abroad.

International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT The integration of low Earth orbit (LEO) satellite constellations with commercial aircraft communication systems presents critical challenges in maintaining continuous connectivity during dynamic flight conditions. Current geostationary satellite systems suffer from high round‐trip latency (>$$ > $$ 500 ms) and inadequate coverage at high ...

Forgoing Nuclear: Nuclear Power Plant Closures and Carbon Emissions in the United States
Southern Economic Journal, EarlyView.ABSTRACT This paper examines the effect of nuclear power plant decommissioning on electricity generation and carbon emissions in the United States. Using data on nuclear reactor closures in the United States between 1993 and 2022 and data on state‐level carbon emissions and electricity generation from the Energy Information Administration (EIA), this ...

Artificial Intelligence for Engineering, EarlyView.ABSTRACT Offshore oil production in Brazil relies on Floating Production Storage and Offloading (FPSO) units, where failures in rotating machinery motivate machine learning–based predictive maintenance. Centralised training is impractical due to privacy constraints, heterogeneous and highly imbalanced local datasets and unreliable satellite ...

Secrecy Outage Probability Analysis for Downlink RIS-NOMA Networks With On-Off Control
IEEE Transactions on Vehicular Technology, 2023 Reconfigurable intelligent surface (RIS) has been regarded as a promising technology since it has ability to create the favorable channel conditions. This paper investigates the secure communications of RIS assisted non-orthogonal multiple access (NOMA) networks, where both external and internal eavesdropping scenarios are taken into consideration ...
