New Generation of Neutron Decay Experiments [PDF]

Journal of Neutron Research, 2005
New generation of neutron decay experiments, which can be done with high accuracy at new Spallation Neutron Sources, are very important for solution of current problems of fundamental physics and for tests of the Standard Model. The open problems of theory related to these experiments and possible approaches to their solutions are discussed.

Stabilization of a nonlinear Euler-Bernoulli viscoelastic beam subjected to a neutral delay [PDF]

Theoretical and Applied Mechanics
An approach is implemented in this article to analyze the decay rate of nonlinear beams according to the Euler–Bernoulli equation in the context of rheological viscoelastic damping deformations taking into account the neutral type delay.

New general decay rates of solutions for two viscoelastic wave equations with infinite memory

Mathematical Modelling and Analysis, 2020
We consider in this paper the problem of asymptotic behavior of solutions for two viscoelastic wave equations with infinite memory. We show that the stability of the system holds for a much larger class of kernels and get better decay rate than the ones ...

Asymptotic behavior of a viscoelastic wave equation with a delay in internal fractional feedback [PDF]

Archives of Control Sciences
We consider the viscoelastic wave equation with a time delay term in internal fractional feedback. By employing the energy method along with the Faedo-Galerkin procedure, we establish the global existence of solutions, subject to certain conditions ...

Asymptotic stability of a quasi-linear viscoelastic Kirchhoff plate equation with logarithmic source and time delay

AIMS Mathematics, 2023
In this paper, a quasi-linear viscoelastic Kirchhoff plate equation with logarithmic source and time delay involving free boundary conditions in a bounded domain is considered. The local existence and global existence are proved, respectively.

The generational decay of Euroscepticism in the UK and the EU referendum [PDF]

Journal of Elections, Public Opinion and Parties, 2017
A prominent feature of media coverage during the UK’s referendum on European Union (EU) membership was the stark difference between the pro-EU young and their Eurosceptic elders, widely assumed to reflect a generational divide. The positive relationship between age and hostility towards the EU is well established in academic research, however only Down,

Existence and stability results of a plate equation with nonlinear damping and source term

Electronic Research Archive, 2022
The main goal of this work is to investigate the following nonlinear plate equation $ u_{tt}+\Delta ^2 u +\alpha(t) g(u_t) = u \vert u\vert ^{\beta}, $ which models suspension bridges.

Properties of hadronicZ decays and test of QCD generators [PDF]

Zeitschrift f�r Physik C Particles and Fields, 1992
Distributions are presented of event shape variables, jet roduction rates and charged particle momenta obtained from 53 000 hadronicZ decays. They are compared to the predictions of the QCD+hadronization models JETSET, ARIADNE and HERWIG, and are used to optimize several model parameters.

General decay for weak viscoelastic Kirchhoff plate equations with delay boundary conditions

Boundary Value Problems, 2017
We consider a weak viscoelastic Kirchhoff plate model with time-varying delay in the boundary. By using a suitable energy and Lyapunov function, we obtain a decay rate for the energy, which depends on the behavior of g and α.
