Variable Anisotropic Hardy Spaces with Variable Exponents

open access: yesAnalysis and Geometry in Metric Spaces, 2021
Let p(·) : ℝn → (0, ∞] be a variable exponent function satisfying the globally log-Hölder continuous and let Θ be a continuous multi-level ellipsoid cover of ℝn introduced by Dekel et al. [12].

Atom decomposition-based intonation modelling [PDF]

open access: yes2015 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2015
Current statistical parametric text-to-speech (TTS) synthesis methods allow production of neutral speech with acceptable quality. However, prosody is often qualified as unsatisfactory and sounding too flat. In this paper, we address intonation modelling for TTS based on physiological aspects of prosody production.

A reaction network of AP decomposition: the missing piece from atomic simulations

open access: yes, 2023
The decomposition network of AP is essential for the combustion performance and safety of solid propellants, while the detailed reaction pathway during thermolysis is far from clear due to the ultrafast and complex reactions involved.

Polar Alignment and Atomic Decomposition

open access: yesCoRR, 2019
Structured optimization uses a prescribed set of atoms to assemble a solution that fits a model to data. Polarity, which extends the familiar notion of orthogonality from linear sets to general convex sets, plays a special role in a simple and geometric form of convex duality.
