Fractal and FractionalIn this paper, we investigate the regularization of the backward problem for a diffusion process with a time-fractional derivative. We propose a novel double-parameter regularization scheme that integrates the quasi-reversibility method for the governing

Parameter fitting in three-flavor Nambu–Jona-Lasinio model with various regularizations
Nuclear Physics B, 2016 We study the three-flavor Nambu–Jona-Lasinio model with various regularization procedures. We perform parameter fitting in each regularization and apply the obtained parameter sets to evaluate various physical quantities, several light meson masses ...

New rule for choice of the regularization parameter in (iterated) tikhonov method
Mathematical Modelling and Analysis, 2009 We propose a new a posteriori rule for choosing the regularization parameter α in (iterated) Tikhonov method for solving linear ill‐posed problems in Hilbert spaces. We assume that data are noisy but noise level δ is given.

Advanced Science, EarlyView.This study investigates how the internal structure of fiber‐reinforced ceramic composites affects their resistance to damage. By combining 3D X‐ray imaging with acoustic emission monitoring during mechanical testing, it reveals how silicon distribution influences crack formation.

Geometry Control Equation of the Circular Ring Tower Based on Unstressed State Amounts
Advances in Civil EngineeringIn high-degree-of–freedom complex structures, the ill-conditioning or singularity of the stiffness matrix is a key factor affecting the accuracy and stability of structural analysis. Regularization techniques are introduced to solve this issue.

Shock and Vibration, 2018 Because structures may be subject to unknown loads and may simultaneously involve unknown parameters and because simple load identification or parameter identification algorithms cannot be applied under such conditions, it is necessary to seek algorithms

On Two‐Parameter Regularized Semigroups and the Cauchy Problem [PDF]
Abstract and Applied Analysis, 2009 Suppose that X is a Banach space and C is an injective operator in B(X), the space of all bounded linear operators on X. In this note, a two‐parameter C‐semigroup (regularized semigroup) of operators is introduced, and some of its properties are discussed.

Solid Harmonic Wavelet Bispectrum for Image Analysis
Advanced Science, EarlyView.The Solid Harmonic Wavelet Bispectrum (SHWB), a rotation‐ and translation‐invariant descriptor that captures higher‐order (phase) correlations in signals, is introduced. Combining wavelet scattering, bispectral analysis, and group theory, SHWB achieves interpretable, data‐efficient representations and demonstrates competitive performance across texture,
