Periodontitis in Patients With Severe Obesity: From the Oral and Gut Microbiota Dysregulation to the Visceral Adipose Tissue Inflammatory and Metabolic Disorders

The FASEB Journal, Volume 40, Issue 9, 15 May 2026.
In patients with severe obesity, periodontitis is associated with oral microbiota dysbiosis which influences gut microbiota composition by increasing Proteobacteria proportion. These alterations are linked to systemic immune and metabolic changes, including higher circulating levels of anti‐Porphyromonas gingivalis lgG and deregulated lipid profile ...

Terahertz Metasurface for Spatial Detection of Full Stokes Parameters and Polarization Imaging

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
This work presents a THz polarization analyzer with significantly improved robustness against nonuniformity. By integrating four polarization‐sensitive meta‐atoms into a meta‐cell, the metalens splits incident light into six polarization components and generates off‐axis focal spots.

Mode and Polarization Division Multiplexing Based on Chalcogenide‐Glass‐on‐Thin‐Film Lithium Niobate

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
High‐index GeSbSe chalcogenide glass loaded on thin‐film lithium niobate enables compact broadband mode‐ and polarization‐division multiplexing. Exploiting direction‐dependent birefringence of x‐cut LNOI, a four‐channel mode (de)multiplexer and asymmetric directional coupler‐based polarization splitter–rotator are demonstrated with great performance in

Terahertz Encryption With a Polarization‐Sensitive Metasurface

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
We propose a dual‐functional terahertz encryption metasurface that enables independent information retrieval in both the near field and the far field within a single device. In the near field, polarization‐selective amplitude modulation reveals textual patterns, whereas in the far field, phase engineering encodes multiple digital data in focal‐spot ...

Symbol‐Level GRAND‐Assisted Detection for Polar‐Coded Spatial Modulation in MIMO Systems

International Journal of Communication Systems, Volume 39, Issue 7, 10 May 2026.
This research presents an integrated polar‐coded spatial modulation (PCSM) transceiver scheme for MIMO transmission over Rayleigh fading channels. The proposed architecture employs linear spatial signal processing for antenna and symbol estimation, followed by symbol‐level guessing random additive noise decoding (symbol‐level GRAND)–assisted detection ...
