Widening the Axion Window via Kinetic and St\"uckelberg Mixings [PDF]

open access: yes, 2015
We point out that kinetic and St\"uckelberg mixings that are generically present in the low energy effective action of axions can significantly widen the window of axion decay constants.

Pseudoscalar Meson Mixing in Effective Field Theory [PDF]

open access: yes, 2001
We show that for any effective field theory of colorless meson fields, the mixing schemes of particle states and decay constants are not only related but also determined exclusively by the kinetic and mass Lagrangian densities. In the general case, these

Effects of Specific Electric Field Stimulation on the Release and Activity of Secreted Acid Phosphatases from Leishmania tarentolae and Implications for Therapy

open access: yesPathogens, 2018
Leishmaniasis is a neglected tropical disease with 1.6 million new cases reported each year. However, there are few safe, effective, and affordable treatments provided to those affected by this disease. Still under-appreciated as potential pharmaceutical

Asymptotic-preserving exponential methods for the quantum Boltzmann equation with high-order accuracy [PDF]

open access: yes, 2013
In this paper we develop high-order asymptotic-preserving methods for the spatially inhomogeneous quantum Boltzmann equation. We follow the work in Li and Pareschi, where asymptotic preserving exponential Runge-Kutta methods for the classical ...

Kinetic Equation with a Constant Magnetic Field [PDF]

open access: yesThe Physics of Fluids, 1960
The collision operator is derived for the case of a spatially homogeneous plasma subject to a constant external magnetic field. A generalization of Lenard's method is employed.

Analysis of DCE-MRI Data using a Nonnegative Elastic Net [PDF]

open access: yes, 2010
We present a nonnegative Elastic Net approach for the analysis of Dynamic Contrast-Enhanced Magnetic Resonance Imaging data. A multi-compartment approach is considered, which is translated into a (restricted) least square model selection problem.

Analysis of kinetics of light scattering by cell suspection during aggregation: mathematical modeling of platelet disaggregation

open access: yesВісник Харківського національногоуніверситету імені В.Н. Каразіна. Серія: Радіофізика та електроніка, 2021
Background. Molecular mechanisms of platelet aggregation are actively studied by methods of molecular cell biology, biochemistry, applied physics, but the problem of modeling the dynamics of this process remains open.
