Three‐Dimensional Array Multicasting of Cylindrical Vector Beams Using Spin‐Multiplexed Dammann Vortex Metasurface

Nanophotonics, Volume 15, Issue 14, 27 July 2026.
This study demonstrates, for the first time, a 3D volumetric cylindrical vector beam (CVB) multicasting architecture that employs multichannel array modes with an operational dimension of 3 × 3 × 5 as information carriers. This approach offers substantial potential for high‐capacity information dissemination in mode‐multiplexed communication networks ...

Lipid and Foam Cell Accumulation as Novel Pathological Features of Benign Prostatic Hyperplasia

The Prostate, Volume 86, Issue 10, Page 1157-1169, July 2026.
ABSTRACT Background Benign prostatic hyperplasia (BPH) encompasses a heterogeneous set of pathological processes that instigate lower urinary tract symptoms (LUTS). Using a mouse model of steroid hormone imbalance–induced lower urinary tract dysfunction, we identified luminal lipid‐laden foamy macrophages, although their presence and contribution to ...

Security‐Enhanced Differential Binary‐Phase‐Shift‐Keying Quantum Key Distribution With a Wavelength‐Switchable Single‐Photon Carrier

Advanced Photonics Research, Volume 7, Issue 6, June 2026.
A single‐chip dual‐wavelength coherent photon source is proposed to add parametric uncertainty and improve the security of single‐photon differential binary‐phase‐shift‐keying quantum key distribution. This wavelength‐uncertain coding or decoying operation enables flexible and secure D‐BPSK‐QKD transmission over a wavelength‐division‐multiplexed ...

A Highly Efficient Two‐Sided Temporal Convolutional Neural Network for Wideband Digital Predistortion of RF Power Amplifiers

International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, Volume 39, Issue 3, May/June 2026.
ABSTRACT Behavioral models for Power Amplifier (PAs), particularly those based on Neural Networks (NNs), often suffer from high computational complexity when handling wideband signals. In this paper, we present a novel behavior model for wideband GaN PAs based on a Two‐Sided Temporal Convolutional Neural Network (TST‐CNN).
