A Machine Learning Parameterization for the Internal Gravity Wave Spectrum

Journal of Geophysical Research: Oceans, Volume 131, Issue 5, May 2026.
Abstract We introduce a stochastic model designed to parametrize the spectral properties of internal waves, using two functions that represent the semidiurnal spectral tidal cusps and the energy continuum between the inertial and the buoyancy frequencies.

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

Harmonic and power spectrum analysis of vertical ground reaction force in patients who have a stroke within 3 months

Experimental Physiology, Volume 111, Issue 5, Page 2528-2542, 1 May 2026.
Abstract Stroke remains a primary cause of disability globally. An in‐depth comprehension of gait impairments following a stroke is vital for crafting effective therapeutic interventions, and vertical ground reaction forces (vGRF) provide valuable insights into these mechanics.

Revisiting Intrinsic Predictability of Wave‐Convection Coupled Bands Over Southern China: Variable and Scale‐Dependent Error Growth Characteristics

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.
Abstract This study investigates the variable‐ and scale‐dependent intrinsic predictability of wave‐convection coupled bands over southern China on 30 January 2018, using 1‐km simulations under varying initial moisture conditions. The predictability time is quantified via the Loss Predictability Index (LPI), defined as the ratio of the forecast error ...

The generalized discrete fourier transform for the computation of the DFT on large sets of data

, 1977
In this paper we consider a generalized form of the Discrete Fourier Transform (DFT), called Generalized Discrete Fourier Transform (GFT). Two fast algorithms are given that allow us to obtain a one-dimensional GFT by evaluating a proper multidimensional GFT.
