Successive Interference Cancellation Decoding With Adaptable Decision Regions for NOMA Schemes
IEEE Access, 2022 In this work, we propose adaptable decision regions in the successive interference cancellation (SIC) decoder for the three-user uplink/downlink non-orthogonal multiple access (NOMA) scheme by exploiting the knowledge of the channel gains.

Phase Diagrams and Piezoelectric Properties of Wurtzite Al1−x−yScxGdyN Heterostructural Alloys
Advanced Science, EarlyView.This study demonstrates ferroelectricity and piezoelectric properties improvement of quaternary wurtzite Al1−x−yScxGdyN${\rm Al}_{1-x-y}{\rm Sc}_x{\rm Gd}_y{\rm N}$ films, guided by density functional theory calculations. Wurtzite Al1−x−yScxGdyN${\rm Al}_{1-x-y}{\rm Sc}_x{\rm Gd}_y{\rm N}$ films have a high optical bandgap, enhanced piezoelectric ...

Small, EarlyView.Wafer‐scale top‐down fabrication yields silicon nanoparticles with exceptional uniformity (CV 1.7%–2.4%), enabling deterministic axis‐ratio tuning. At AR ≈$\approx$ 2.1, electric–magnetic dipoles overlap on‐resonance, producing near‐Kerker forward scattering (F/B ≈$\approx$ 12.5).

History, EarlyView.Abstract In the summer of 1919, W. T. Goode, the Manchester Guardian’s special correspondent in Russia and the Baltic, was arrested in the Estonian capital Tallinn and briefly detained aboard a British warship. Goode's detention caused a furore, leading to accusations of kidnap, heated commentary in the press and questions in parliament.

Sanctions, National Security, and Free Speech
Global Policy, EarlyView.ABSTRACT A fundamental, but largely overlooked, aspect of the New Washington Consensus is the use of national security arguments to restrict speech and punish disfavored speakers. Although the United States has a longer history of using sanctions to restrict speech in the terrorism context, it has recently applied sanctions to restrict political speech,
