Dynamic Cell Division for Interference Management in Satellite Direct‐to‐Cell Systems
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT Direct‐to‐cell (D2C) connectivity enables future non‐terrestrial networks to provide service directly to standard terrestrial user equipment (UE) when terrestrial networks (TN) are unavailable. In this work, the satellite system is considered as a secondary network that supplements existing TN coverage while minimizing interference to the ...

Geometric Characterization of LEO–GEO Inter‐Satellite Links for Bidirectional Communications
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT Incorporating geosynchronous Earth orbit (GEO) and low Earth orbit (LEO) satellites can extend communication services far beyond the reach of terrestrial infrastructure. A key enabler of such architectures is the establishment of inter‐satellite links (ISLs) between LEOs and GEOs to support bidirectional communications.

Sustainable Development, EarlyView.ABSTRACT Understanding the environmental impact of food production is critical to promoting sustainable consumption patterns. This study explores the gap between consumers' perceived water footprint (PWF) and the actual water footprint (AWF) of selected agri‐food products in Italy, including crop‐ and animal‐based products. A survey conducted through a

Small, EarlyView.Open‐shell quinoids with intrinsic spins are assembled into chiral supramolecular structures via blending with chiral additives. Thermal annealing induces stable co‐crystallization, leading to a 30‐fold amplification of chirality (gabs = 1.23 × 10−2). Significantly, this study represents the first integration of spin‐possessing chiral assemblies into ...

Small, EarlyView.ABSTRACT The rapid expansion of the Internet of Things (IoT) and wearable electronics necessitates sustainable power sources to replace the limited electrochemical battery. While mechanical energy harvesting offers a promising solution, traditional harvesters face challenges of irregular and low−frequency environmental sources. This review presents the
