General equation for Zeno-like effects in spontaneous exponential decay [PDF]
, 1999 It was shown that different mechanisms of perturbation of spontaneous decay constant: inelastic interaction of emitted particles with particle detector, decay onto an unstable level, Rabi transition from the final state of decay (electromagnetic field ...

General properties of the decay amplitudes for massless particles [PDF]
Nuclear Physics B, 1996 We derive the kinematical constraints which characterize the decay of any massless particle in flat spacetime. We show that in perturbation theory the decay probabilities of photons and Yang-Mills bosons vanish to all orders; the decay probability of the graviton vanishes to one-loop order for graviton loops and to all orders for matter loops.

HADRONIC B DECAYS: A GENERAL APPROACH [PDF]
International Journal of Modern Physics A, 2007 In this paper, we propose a general approach for describing hadronic B decays. Using this method, all amplitudes for such decays can be expressed in terms of contractions, though the matrix elements are not evaluated. Many years ago, Buras and Silvestrini proposed a similar approach. However, our technique goes beyond theirs in several ways. First, we

General decay of solutions of a viscoelastic equation
Journal of Mathematical Analysis and Applications, 2007 AbstractIn this paper we consider the following viscoelastic equation:utt−Δu+∫0tg(t−τ)Δu(τ)dτ=0, in a bounded domain, and establish a general decay result which is not necessarily of exponential or polynomial type. This work generalizes and improves earlier results in the literature.

Decay of correlations for nonuniformly expanding systems with general return times [PDF]
, 2011 We give a unified treatment of decay of correlations for nonuniformly expanding systems with a good inducing scheme. In addition to being more elementary than previous treatments, our results hold for general integrable return time functions under fairly

Ultrafast generation and decay of a surface metal [PDF]
Nature Communications, 2021 AbstractBand bending at semiconductor surfaces induced by chemical doping or electric fields can create metallic surfaces with properties not found in the bulk, such as high electron mobility, magnetism or superconductivity. Optical generation of such metallic surfaces on ultrafast timescales would be appealing for high-speed electronics.

General Decay of the Moore–Gibson–Thompson Equation with Viscoelastic Memory of Type II
Journal of Function Spaces, 2022 This study deals with the general decay of solutions of a new class of Moore–Gibson–Thompson equation with respect to the memory kernel of type II. By using the energy method in the Fourier space, we establish the main results.

Natural Image Decay With a Decay Effects Generator
IEEE Access, 2023 We present a novel framework for simulating time-varying decay effects for natural images. Conventional methods assume the input image includes enough decay information and uses the color or texture information of the decayed regions to transfer its effect to the non-decayed regions.

General decay for a viscoelastic von Karman equation with delay and variable exponent nonlinearities
Boundary Value Problems, 2022 In this paper, we consider a viscoelastic von Karman equation with damping, delay, and source effects of variable exponent type. Firstly, we show the global existence of solution applying the potential well method.

Partial stability analysis of stochastic differential equations with a general decay rate
Journal of Engineering Mathematics, 2021 This paper is concerned with the almost sure partial practical stability of stochastic differential equations with general decay rate. We establish some sufficient conditions based upon the construction of appropriate Lyapunov functions.
