Path‐Based Deep Reinforcement Learning for On‐Board Routing in Satellite Constellation Networks

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Efficient usage of available network resources is a crucial factor for broadband services in interconnected satellite constellations. To meet required quality of service standards under heavy network loads, it is essential to optimize traffic distribution among the intersatellite links. To address this challenge, we propose an adaptive traffic

The Dynamic Impact of the Energy Transition on Food Security in Developing Countries

Sustainable Development, EarlyView.
ABSTRACT In the context of persistent food insecurity and the global push for the transition toward clean energy in developing countries, understanding the association between clean energy access and food affordability is increasingly important to inform multisectoral policy interventions. Against this background, this study explores the dynamic impact

How Climate Change Shapes Environmental, Social, and Governance (ESG) Performance in the MENA Countries

Sustainable Development, EarlyView.
ABSTRACT Climate change, political stability, and sustainability are three central factors that interact and serve as key drivers of achieving the Sustainable Development Goals (SDGs) in the MENA (Middle East and North Africa) region. Accordingly, this paper aims to fill a vital research gap by examining the impacts of climate change, natural resource ...

Spectral validity and spindle detection of wearable frontal Electroencephalography: A per‐subject calibration framework and systematic validation against polysomnography using the Wearanize+ dataset

Sleep Research, EarlyView.
Abstract Background Wearable Electroencephalography (EEG) devices enable home sleep monitoring but require systematic spectral validation before their physiological outputs can serve as proxies for polysomnographic features. Aims This study provides comprehensive spectral validation of the Zmax EEG headband against concurrent polysomnography (PSG ...

Regulation, Taxation, and Resources: Unpacking Greenhouse Gas Emission Drivers Across G7 Economies

Thunderbird International Business Review, EarlyView.
ABSTRACT Advanced economies are under growing pressure to downscale greenhouse gas (GHG) emissions without undermining growth, yet G7 (Group of Seven) nations, representing almost 10% of the world's population, still generate one quarter of global GHGs.
