Beta decay rates evaluated within the Gross Theory using experimental data for the Gamow-Teller resonance parameter
(Sociedade Brasileira de Física, 2020-06)
We improve the results for the β−-decay rates obtained within the context of the Gross Theory of Beta Decay (GTBD) by using new values of the parameter σN related to the standard deviation for the Gamow-Teller resonance: ...
Effect of Helicity and Rotation on the Free Decay of Turbulent Flows
(American Physical Society, 2009-06)
The self-similar decay of energy in a turbulent flow is studied in direct numerical simulations with and without rotation. Two initial conditions are considered: one nonhelical (mirror symmetric) and one with maximal ...
Analytical models of soil and litter decomposition: Solutions for mass loss and time-dependent decay rates
(Elsevier, 2012-07)
Combining decomposition data with process-based biogeochemical models is essential to quantify the turnover of organic carbon (C) in surface litter and soil organic matter (SOM). Long-term decomposition may be suitably ...
Effects of Antineutrino mass on β−-Decay Rates Calculated Within the Gross Theory of Beta Decay
(Sociedade Brasileira de Física, 2020-01)
We analyze the effect of the antineutrino mass over the β −-decay rates calculated within the scheme of the Gross Theory of Beta Decay (GTBD). We give a non null value to the mass of the antineutrino participating in β ...
Stabilization of the wave equation with Neumann boundary condition and localized nonlinear damping
(EUDOXUS PRESS, LLC, 2009)
We show that the solutions of the wave equation with potential, Neumann boundary conditions and a locally distributed nonlinear damping, decay to zero, with an algebraic rate, that is, the total energy E(t) satisfies for ...
Decay of Batchelor and Saffman rotating turbulence
(American Physical Society, 2012-12)
The decay rate of isotropic and homogeneous turbulence is known to be affected by the large-scale spectrum of the initial perturbations, associated with at least two canonical self-preserving solutions of the von Kármán-Howarth ...
Comparison of Nonmesonic Hypernuclear Decay Rates Computed in Laboratory and Center-of-Mass Coordinates
(Amer Inst Physics, 2014-01-01)
In this work we compute the one-nucleon-induced nonmesonic hypernuclear decay rates of He-5(Lambda), C-12(Lambda) and C-13(Lambda) using a formalism based on the independent particle shell model in terms of laboratory ...
Mindlin–Timoshenko systems with Kelvin–Voigt: analyticity and optimal decay rates
(ElsevierAcademic PressSan Diego, 2014-09)
This paper is concerned with asymptotic stability of Mindlin–Timoshenko plates with dissipation of Kelvin–Voigt type on the equations for the rotation angles. We prove that the corresponding evolution semigroup is analytic ...
