A Multimodal Deep Learning Based Framework for Early and Accurate Diagnosis of Depression Using Electroencephalography and Event‐Related Potential Signals

Applied AI Letters, Volume 7, Issue 3, October 2026.
Cross Wavelet Transform (XWT) is combined with a pre‐trained AlexNet to extract rich time‐frequency features from non‐stationary EEG signals. Also, the proposed framework simultaneously extracts and integrates spatial (Node2vec), time‐frequency (XWT + AlexNet), and spectral (PSD + TSCN) features from EEG and ERP signals within a parallel architecture ...

Design of Large‐Aperture Hybrid Refractive Metalens System

Nanophotonics, Volume 15, Issue 18, 25 September 2026.
An all‐germanium hybrid refractive–metalens system was constructed by integrating a planar Ge metalens with a single aspheric Ge lens, enabling compact wavefront correction in the LWIR band. The all‐Ge hybrid architecture simplifies conventional multi‐element infrared optics into a lightweight integrated imaging system while maintaining effective ...

Novel Scheme for Image Encryption Combining 2D Logistic-Sine-Cosine Map and Double Random-Phase Encoding

IEEE Access, 2019
In this paper, we present a 2D Logistic-Sine-Cosine map (2D-LSCM) which is based on the classical 2D Logistic, Sine and Cosine maps. Performance analysis shows that it has larger chaotic range, bigger Lyapunov exponent and more complex chaotic behavior ...
