Rapid Nasal Breathing as a Biometric Trigger: High‐Accuracy Electroencephalogram‐Based Authentication for Clinical Applications

The Clinical Respiratory Journal, Volume 20, Issue 1, January 2026.
Our study demonstrates rapid nasal breathing‐evoked EEG signals enable high‐accuracy (98.3%) biometric authentication via a hybrid ResNet‐Swin Transformer model. This noninvasive approach eliminates external stimuli, offering secure patient identification for critical respiratory care settings, such as ventilator access and continuous monitoring ...

Quantitative Electroencephalographic Biomarkers for Repetitive Transcranial Magnetic Stimulation Treatment Response Prediction in Mild Cognitive Impairment: A Pilot Study Protocol for Multi‐Center, Assessor‐Blinded, Open‐Label Clinical Trial

Brain and Behavior, Volume 15, Issue 11, November 2025.
Repetitive transcranial magnetic stimulation (rTMS) enhances neural plasticity in mild cognitive impairment (MCI), but treatment success varies across individuals. In this pilot multicenter trial, quantitative EEG (QEEG) signals recorded before therapy are analyzed to identify predictors of clinical response.

Wideband Millimeter‐Wave Balun‐Diplexer Based on a Novel Coupled Marchand Architecture for Compact Footprint and Phased‐Array Integration

Microwave and Optical Technology Letters, Volume 67, Issue 11, November 2025.
ABSTRACT This letter presents the first reported wideband balun‐diplexer for mm‐wave applications, designed for shared‐aperture full‐duplex array systems. By integrating balun and diplexer functionalities in a single component, we enable per‐element self‐interference suppression, while also facilitating the interface between the balanced feed of the ...
