This engineering paper reviews and classifies beamforming techniques in 5G New Radio and examines beam management procedures at Layer 1 and Layer 2. It analyzes the spectral spectrogram of Synchronization Signal Blocks (SSBs) to illustrate how configuration parameters influence spectral occupancy and…

This paper discusses how rising man-made EMF from modern wireless technologies motivates careful regulation to keep exposure below levels expected to cause harm. It argues current regulations may not strictly constrain EMF when multiple nearby devices transmit simultaneously. The authors propose a…

This engineering study examines how the spectral mismatch between mobile phone flash LEDs and modern display gamuts influences smartphone camera color reproduction. Using a CIECAM02-based metric and an evaluation method grounded in raw camera data and a Digital ColorChecker SG, the authors propose optimized flash LED…

This paper presents a theoretical description of nonequilibrium dynamics in a three-dimensional Fermi-Hubbard model driven by an external electric field. The authors report direction-dependent damping of Bloch oscillations and the emergence of a long-lived transient prethermalized state over a broad range of field…

This theoretical/physics study analyzes the spectrum of electron-phonon complexes in monolayer graphene in a perpendicular quantizing magnetic field. It reports that near the threshold of optical phonon emission, standard perturbation theory fails for calculating the scattering amplitude. The authors describe new…

This Letter presents a method for constructing solar-wind-like magnetic fields that are nearly constant in magnitude, divergence-free, and match any specified fluctuation power spectrum. The approach selects relative phases between two polarizations per wave vector to minimize variance in field magnitude while…

This in vitro FTIR study examined human haemoglobin aqueous solutions exposed to a 200 mT static magnetic field for 3 and 7 hours, with and without the disaccharides sucrose and trehalose. The authors report spectral changes (amide A decrease and reduced CH(3) stretching) in haemoglobin dissolved in bi-distilled…

This theoretical condensed-matter study examines how an electric field affects the electronic spectrum and localization in quasiperiodic chains modeled with Harper and Fibonacci potentials. It reports localized ladder spectra under strong fields and smoothing with linearly decreasing gaps under weak fields. When…

This paper discusses the Czjzek model for distributions of electric field gradient (EFG) tensors in disordered solids and highlights its underlying assumptions and characteristics. It then introduces an extended model that combines a defined local EFG environment with an adjustable Gaussian (Czjzek) noise term to…

This study reports solid-state NMR (13C and 15N MAS) measurements on CuCN·N2H4 to extract copper quadrupole coupling constants and characterize cyanide ordering. Ab initio calculations were used to determine electric field gradient and chemical shielding tensor orientations needed for spectral analysis. The authors…

This paper models biological proton pumping in cytochrome c oxidase under an applied oscillating electric field. The authors report that proton pumping efficiency and steady-state electronic currents vary significantly with the field’s frequency and amplitude. A spectral analysis is described as supporting dominant…

This theoretical/physics study investigates spectral properties of a spin-1/2 Heisenberg antiferromagnet on an anisotropic triangular lattice in a magnetic field. It reports that interchain interactions in a magnetic field generate dominant modes that behave as quasiparticles, featuring anomalous incommensurate…

This engineering study reports spectroscopic determination of net electric field distribution in a dielectric barrier surface glow discharge in low-pressure air. Optical emission spectroscopy was used to infer electric field distribution from the intensity ratio of nitrogen spectral lines at 391.4 nm and 337.1 nm.…

This in vitro study examined terahertz electromagnetic radiation at NO-related spectral frequencies and its effects on blood rheology in patients with unstable angina treated with the NO donor isoket. The abstract reports that irradiated isoket had a better normalizing effect on blood viscosity and erythrocyte…

This study measured satellite structures of second- and third-harmonic spectra reflected from solid targets during femtosecond laser–plasma interactions using an optical multi-channel spectrometer. Red-shifted satellite structures of 2ω0 and 3ω0 were observed, and at ~10^18 W/cm^2 the inferred spontaneous magnetic…
