Reconfigurable Curved Beams at Terahertz Frequencies Using Inverse‐Designed Bilayer Diffractive Structures

Advanced Photonics Research, Volume 7, Issue 5, May 2026.
An inverse‐designed bilayer diffractive structure enables reconfigurable propagation of two distinct curved beams via 180° rotation of the second layer. Curved electromagnetic beams at terahertz (THz) frequencies have recently emerged as a powerful example of wavefront engineering, with applications in imaging and high‐capacity wireless communications.

Computationally Efficient Light Field Video Compression Using 5-D Approximate DCT

Journal of Low Power Electronics and Applications
Five-dimensional (5-D) light field videos (LFVs) capture spatial, angular, and temporal variations in light rays emanating from scenes. This leads to a significantly large amount of data compared to conventional three-dimensional videos, which capture ...

Metasurfaces and Metadevices for Topological Electromagnetic Waves

Advanced Physics Research, Volume 5, Issue 5, May 2026.
Optical topologies refer to diverse topological localized structures made by diverse parameters of light fields, such as vortices, skyrmions, and hopfions. This article navigates a direction of metasurface‐based integrated devices for generation, manipulation and detection of novel topologies of light, which would be a rapidly growing interdisciplinary

Capturing State‐of‐Charge‐Dependent Efficiency in Battery Energy Storage Systems: A Bernoulli Model Approach

Battery Energy, Volume 5, Issue 3, May 2026.
Conventional battery energy storage system models assume constant efficiencies, overlooking key physical limitations. This work introduces an analytical model with realistic state‐of‐charge (SOC)‐dependent efficiencies and charge acceptance, predicting that system operation concentrates in intermediate SOC ranges—a critical, overlooked behaviour ...

Neural Rate-Adaptive LDPC Decoding for the Slepian-Wolf Problem

IEEE Open Journal of Signal Processing
Distributed source coding (DSC) enables efficient compression of correlated sources by performing independent encoding and joint decoding. Slepian-Wolf coding plays a central role in DSC, as it allows near-lossless compression of correlated data at rates

Construction of Noise Reduction and Sound Quality Optimization Model for Music Transmission Signals Based on Deep Learning

Engineering Reports, Volume 8, Issue 5, May 2026.
The study collects typical music samples and multiple types of noise data, preprocesses the signals using time‐frequency domain feature extraction methods, and on this basis designs a deep neural network structure that integrates convolutional neural networks and perception optimization mechanisms.

Cyclic Peptide Conformational Landscapes Through the Lens of Mass Spectrometry and Orthogonal Spectroscopy

Journal of Mass Spectrometry, Volume 61, Issue 5, May 2026.
ABSTRACT Cyclic peptides occupy a structurally dynamic region of chemical space, where function often arises from ensembles rather than a single dominant fold. Closed backbones, frequent N‐methylation, heteroatoms, unnatural amino acids, and a strong propensity for metal coordination create dense conformational and coordination landscapes that ...
