Direct evidence for electrostriction‐enhanced piezoelectricity in poly(vinylidene fluoride‐co‐trifluoroethylene) random copolymers

Responsive Materials, EarlyView.
Direct experimental evidence for electrostriction‐enhanced piezoelectricity is obtained for a quenched‐stretched‐annealed‐poled P(VDF‐TrFE) 52/48 mol.% random copolymer using time‐resolved small‐angle X‐ray scattering and wide‐angle X‐ray diffraction. Upon stretching up to 6% strain, the crystallinity (xc) increases 10% at the expense of the contents ...

Digital Twin‐Based Optimization of Service Availability in LEO Mega Constellations Considering Handover Delays in Open RAN

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT As non‐terrestrial networks (NTNs) become integral to future 6G systems, ensuring seamless connectivity and service continuity over low Earth orbit (LEO) satellite constellations is essential. This work investigates the impact of open radio access network (RAN) functional splits on handover performance in NTNs, focusing on minimizing service ...

Three‐Year Propagation Experiment at Ku‐, Ka‐, and Q‐Band in French West Indies

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT From January 2021 to December 2023, the Office National d'Etudes et de Recherches Aérospatiales (ONERA) and the Centre National d'Etudes Spatiales (CNES) conducted a three‐year Earth‐space propagation measurement campaign in Guadeloupe. The experiment used beacon receivers deployed in Pointe‐à‐Pitre airport to record signals at 11.2, 19.7, and

Fair and Equitable Land Access (FELA) by Development Projects: Enhancing Governance for Sustainable Development Outcomes When Projects Displace People

Sustainable Development, EarlyView.
ABSTRACT Displacing people to make way for development projects is contentious. Empirical research demonstrates that neither human rights guidelines nor multilateral lenders' standards guarantee positive, sustainable outcomes for displaced people. With multiple new displacing projects proposed globally, including for renewable energy, we propose a new ...

Mapping School Accessibility in Africa: High‐Resolution Spatial Analysis Uncovers Inequalities in Education Access

Sustainable Development, EarlyView.
ABSTRACT Education is a cornerstone of sustainable development, yet large disparities in access persist across and within countries—particularly in Africa, where millions remain underserved. Among several factors influencing educational participation, physical accessibility to schools (in terms of travel time) is not comprehensively understood ...
