On the Optimal Selection of Mel‐Frequency Cepstral Coefficients for Voice Deepfake Detection

Expert Systems, Volume 43, Issue 5, May 2026.
ABSTRACT The continuous evolution of techniques for generating manipulated audio, known as voice deepfakes, and the widespread availability of tools that produce convincing forgeries have created an urgent need for reliable detection methods. This work considers the dimensionality of Mel‐Frequency Cepstral Coefficients (MFCCs) as a core design variable

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 ...

AIEgens: An Exemplary Template for “One‐for‐All” Multimodal Phototheranostics

Aggregate, Volume 7, Issue 4, April 2026.
This review establishes a consensus that AIEgens serve as a quintessential template for “one‐for‐all” multimodal phototheranostics and systematically articulates the underlying rationale from a photophysical perspective. It comprehensively examines corresponding molecular engineering principles and performance optimization tactics, framed within the ...

Stable Model Reduction for Time‐Domain Room Acoustics: A Structure‐Preserving Formulation for Complex Boundaries

International Journal for Numerical Methods in Engineering, Volume 127, Issue 5, 15 March 2026.
ABSTRACT This work presents novel structure‐preserving formulations for stable model order reduction in the context of time‐domain room acoustics simulations. A solution to address the instability in conventional model order reduction formulations based on the Linearized Euler Equations is derived and validated through numerical experiments.

Ultra‐Efficient 0.1 V cm Lithium Niobate Modulator with >$\gt$ 200 GHz Bandwidth Using a High‐Permittivity Bragg Waveguide

Advanced Photonics Research, Volume 7, Issue 3, March 2026.
This work demonstrates thin‐film lithium niobate Mach–Zehnder modulators. One of these modulators achieves a voltage‐length product of 0.1 V cm, a driving voltage of 1 V, a device length of 1 mm, and a bandwidth exceeding 200 GHz. A high‐permittivity cladded Bragg grating waveguide is utilized to enhance modulation efficiency, enabling low‐voltage and ...
