Molecular Characterizations of Anisotropic Mixed-Norm Hardy Spaces and Their Applications

open access: yesMathematics, 2021
Let p→∈(0,∞)n be an exponent vector and A be a general expansive matrix on Rn. Let HAp→(Rn) be the anisotropic mixed-norm Hardy spaces associated with A defined via the non-tangential grand maximal function.

Separation of ions with the same charge to mass ratio from a collision experiment [PDF]

open access: yesJournal of the Serbian Chemical Society, 2000
Some atomic collision experiments lead to ions having identical q/m ratio, as well as average velocity, so that standard electric and magnetic analyzers are not able to identify them separately.

Calculation of the Interference Coefficient of the Polyatomic Molecular Structure of DNA

open access: yesJournal of Biomedical Photonics & Engineering, 2023
This paper shows the calculation of the DNA interference coefficient and uses it to obtain the spectrum of the interaction of an ultrashort laser pulse with a molecule. The calculation is based on a simplified model of the molecule.
