Routing and Downlink Resource Allocation for Multicast Traffic in LEO Satellite Constellations
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT In this work, we optimize unicast and multicast traffic delivery over non‐terrestrial networks (NTNs) to users on the ground through direct satellite downlink (DL). We consider a gateway‐free mesh architecture with low Earth orbit (LEO) satellites interconnected via inter‐satellite links (ISLs), where unicast and multicast services compete for

Long‐Term Propagation Measurements in Madrid in a Q‐Band Satellite‐to‐Earth Link
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT The Q/V band (40/50 GHz) is gaining interest as satellite operators will need larger bandwidth to be able to provide their services, which are experiencing an increasingly high demand. An accurate characterization of the satellite‐to‐Earth propagation channel is of paramount importance to guarantee a high level of quality of service, by ...

Restoring End‐to‐End Transport With QUIC on Satellite Paths
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT Slow Start is a key congestion control mechanism used to assure a safe response to overload of a path across the Internet. This mechanism increases the startup time taken by the sender to reach the capacity available across the path. The benefit becomes significant on paths with a high bandwidth‐delay product.

Sustainable Development, EarlyView.ABSTRACT This study examines how home‐ and host‐country institutions jointly shape the impact of foreign direct investment (FDI) on firms' climate action commitments (CAC) in emerging markets. Drawing on New Institutional Economics and Varieties of Capitalism, we conceptualize FDI as a mechanism of institutional transmission through which multinational

Sustainable Development, EarlyView.ABSTRACT The fifth industrial revolution (I5.0), which is based on the utilization of interconnected data for efficient resource usage in meeting human requirements, proposes efficient solutions to resource constraint situations. However, the transition to I5.0 in the health sector is not easy and has to face several obstacles.

Novel half-duplex relay strategy and its resource allocation
Tongxin xuebao, 2009 Conventional time-division half-duplex relay strategies based on amplify-and-forward or decode-and-forward strategy could relieve relay nodes from full-duplex requirement but lead to degraded spectrum efficiency.

Sustainable Development, EarlyView.ABSTRACT Across garment factories in the Global South, the promise of “ethical fashion” coexists with poverty wages and retaliation. This study examines why the global call for decent work has not improved labor conditions in Bangladesh's ready‐made garment industry.

Sustainable Development, EarlyView.ABSTRACT The role of diet in individual and planetary health is increasingly scrutinised as consumers are encouraged to make food choices that balance health and sustainability, particularly with beef. While prior research has considered reduction from the perspective of alternate product acceptance, the social context of beef is less understood. Media

Deepening the real options debate: Real options as dynamic optimization
Strategic Management Journal, EarlyView.Abstract Research Summary Is real option theory useful for management research? This topic was hotly debated two decades ago. Real options were said to be inapplicable to management research and to lack conceptual distinctiveness. Whereas responses to the claim about the non‐distinctiveness of real options were disparate, the concern about the theory's
