Evolutions of equatorial ring current ions during a magnetic storm

open access: yesEarth and Planetary Physics, 2020
In this paper, we present evolutions of the phase space density (PSD) spectra of ring current (RC) ions based on observations made by Van Allen Probe B during a geomagnetic storm on 23–24 August 2016.

Reaction–diffusion with stochastic decay rates [PDF]

open access: yesPhysical Chemistry Chemical Physics, 2017
Microscopic physical and chemical fluctuations in a reaction–diffusion system lead to anomalous chemical kinetics and transport on the mesoscopic scale. Emergent non-Markovian effects lead to power-law reaction times and localization of reacting species.

Classification of convergence rates of solutions of perturbed ordinary differential equations with regularly varying nonlinearity

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2016
In this paper we consider the rate of convergence of solutions of a scalar ordinary differential equation which is a perturbed version of an autonomous equation with a globally stable equilibrium.

Polynomial decay rate for a new class of viscoelastic Kirchhoff equation related with Balakrishnan-Taylor dissipation and logarithmic source terms

open access: yesAlexandria Engineering Journal, 2020
In this paper, a polynomial decay rate of Kirchhoff’s nonlinear viscoelastic viscoelastic equation solution related with Balakrishnan-Taylor dissipation solution and logarithmic source terms is obtained, where we obtain the result of energy decay of ...

First Lattice Calculation of the QED Corrections to Leptonic Decay Rates. [PDF]

open access: yesPhysical Review Letters, 2017
The leading-order electromagnetic and strong isospin-breaking corrections to the ratio of K_{μ2} and π_{μ2} decay rates are evaluated for the first time on the lattice, following a method recently proposed.

On the decay rate of sunspots [PDF]

open access: yesGeophysical Research Letters, 2003
We have analyzed the decay of 32 sunspots observed during the years 1988 through 2001 at the San Fernando Observatory (SFO). The data are from digital images obtained in the red (672 nm) with the Cartesian Full Disk Telescope No.1 (CFDT1). We find that the rate of decay is strongly correlated with the total sunspot area and the umbral to total area ...

Differential decay rates of CP-even and CP-odd Higgs bosons to top and bottom quarks at NNLO QCD [PDF]

open access: yesJournal of High Energy Physics, 2018
A bstractWe consider the decay of a neutral Higgs boson of arbitrary CP nature to a massive quark antiquark pair at next-to-next-to-leading order in perturbative QCD. Our analysis is made at the differential level using the antenna subtraction framework.

Overview of Numerical Simulations for Calculating In-Plasma β-Decay Rates in the Framework of PANDORA Project [PDF]

open access: yesEPJ Web of Conferences, 2023
β-decay rates are essential inputs in stellar nucleosynthesis models to explain observed nuclear abundances. While current models continue to use terrestrial values, experiments in storage rings indicate strong divergence between decay rates of neutral ...
