Kinetic studies on the reaction between dicyanocobinamide and hypochlorous acid. [PDF]

open access: yesPLoS ONE, 2014
Hypochlorous acid (HOCl) is a potent oxidant generated by myeloperoxidase (MPO), which is an abundant enzyme used for defense against microbes. We examined the potential role of HOCl in corrin ring destruction and subsequent formation of cyanogen ...

A dual approach to structure constants for K-theory of Grassmannians [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2020
The problem of computing products of Schubert classes in the cohomology ring can be formulated as theproblem of expanding skew Schur polynomial into the basis of ordinary Schur polynomials. We reformulate theproblem of computing the structure constants

Evaluation of the true-strength characteristics for isotropic materials using ring tensile test

open access: yesNuclear Engineering and Technology, 2021
The paper proposes a technique for reconstructing the true hardening curve of isotropic materials from ring tensile tests. Neutron irradiated 42XNM alloy tensile properties were investigated.

Influence of Growth Ring Number and Width on Elastic Constants of Poplar

open access: yesBioResources, 2023
The objective of this work was to evaluate the effect of growth ring number (specimens including 2, 4, and 6 rings from the bark) and growth ring width on elastic constants in the radial direction of Populus x canadensis, which has not been revealed ...

The Structural Design of a Complete Band Gap using Non-Uniform Photonic Crystals with Low Index Material

open access: yesMajlesi Journal of Electrical Engineering, 2023
This study presents a photonic bandgap formation in a non-uniform 2D photonic crystal structure with low index rods relative to the air background. In order to find an absolute photonic band gap formation, photonic lattices of two non-uniform square and ...

Interpolation inequalities and spectral estimates for magnetic operators [PDF]

open access: yes, 2018
We prove magnetic interpolation inequalities and Keller-Lieb-Thir-ring estimates for the principal eigenvalue of magnetic Schr{\"o}dinger operators. We establish explicit upper and lower bounds for the best constants and show by numerical methods that ...
