From Quantity to Reactivity: Advancing Kinetic‐Based Antioxidant Testing Methods for Natural Compounds and Food Applications

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 24, Issue 4, July 2025.
ABSTRACT Traditional antioxidant testing methods primarily focus on quantifying antioxidant capacity but fail to capture their reactivity and effectiveness over time. Kinetic‐based methods provide a deeper understanding of antioxidant performance by assessing reaction rates and inhibition mechanisms.

An algorithm and computer program to locate real zeros of real polynomials [PDF]

open access: yes
A method for reliably extracting real zeros of real polynomials using an expanded two-point secant and bisection method is formed into an algorithm for a digital computer, and a computer program based on this algorithm is presented.

Are there any Julia sets for the Laguerre iteration function? [PDF]

open access: yes, 2003
For polynomials some of whose zeros are complex, little is known about the overall convergence properties of the Laguerre's method. The existence of free critical points of the Laguerre function as applied to one-parameter families of quadratic and cubic

Spatially Controlled Optical Vortex Generation Using Low‐Loss Antimony Telluride Metasurfaces

open access: yesAdvanced Photonics Research, Volume 6, Issue 6, June 2025.
The spatially varying vortex beams with the customizable propagation trajectory and the controllable topological charge evolution are demonstrated using the Sb2Te3‐based plasmonic metasurfaces. Benefiting from the dispersion‐free property of the Pancharatnam–Berry phase and the broadband response of polarization conversion efficiency of the nanobrick ...

Precision Construction of Chiral Optical Fields with Nine Controllable Degrees of Freedom

open access: yesAdvanced Photonics Research, Volume 6, Issue 6, June 2025.
Chiral optical fields (COFs) offer multiple controllable degrees of freedom (DOFs), enabling applications in optical tweezers, manufacturing, and encryption. However, achieving precise sidelobe control remains a challenge. This work introduces a modular multilayer annular phase plate to fine‐tune COFs by manipulating nine DOFs.

The Orthogonal QD-Algorithm [PDF]

open access: yes, 1998
The orthogonal qd-algorithm is presented to compute the singular value decomposition of a bidiagonal matrix. This algorithm represents a modification of Rutishauser's qd-algorithm, and it is capable of determining all the singular values to ...
