Evolution of the EU broadband policy: Towards an integrated framework? [PDF]
Since more than two decades, broadband has been recognized in the EU as having great benefits to economic and social development.This recognition is evident in the first EU policy document on the telecommunications market - the 1987 Green Paper - which ...

Advanced Science, EarlyView.Anisotropic wood carbon sponge/SiO2 aerogel composites are constructed, revealing a robust direction‐dependent permittivity ordering (tangential > radial > axial). The radial direction delivers an ultra‐broadband effective absorption bandwidth of 11.6 GHz at only 4.95 mm, while the tangential direction offers superior compressibility and thermal ...

Residential Broadband Availability: Evidence from Kentucky and North Carolina [PDF]
I analyze the determinants of county-level broadband availability to gauge the extent to which the rural-urban broadband gap has narrowed and the factors that underlie that narrowing.

Broadband Properties of the Harmonic of Type-C Quasiperiodic Oscillation in MAXI J1348-630
The Astrophysical JournalHarmonics are common features of quasiperiodic oscillations (QPOs) in black hole X-ray binaries; however, their physical origins remain poorly understood. Using broadband Insight-HXMT data, we investigated the Type-C QPO harmonic in MAXI J1348−630.

Polarization of decayless kink oscillations in a 3D MHD coronal loop model
Astronomy & AstrophysicsDecayless kink oscillations are frequently observed in solar coronal loops and are considered potential contributors to coronal heating. Despite the ubiquity of this wave phenomenon, its driving mechanism remains unclear.

Acoustically Activatable Drug‐Loaded Nanodroplets for Mechanochemical Therapy in Solid Tumors
Advanced Science, EarlyView.Microfluidically fabricated drug‐loaded nanodroplets are sequentially activated by dual‐frequency ultrasound through acoustic droplet vaporization followed by bubble collapse, enabling spatially controlled drug release and mechanical tumor fractionation, resulting in synergistic mechanochemotherapy and prolonged survival.

Activation of Metal Complexes With Ultrasound Waves for Targeted Anticancer Therapy
Angewandte Chemie International Edition, EarlyView.Ultrasound enables non‐invasive activation of metal‐based therapeutics deep within tumors. Acoustic cavitation can drive sonodynamic reactive oxygen species generation or mechanochemical metal–ligand bond dissociation, enabling controlled release of bioactive payloads.
