A study of fractional order Ambartsumian equation involving exponential decay kernel
: Recently, non-singular fractional operators have a significant role in the modeling of realworld problems. Specifically, the Caputo-Fabrizio operators are used to study better dynamics of memory processes.

Probing the nonexponential decay regime in open quantum systems
The most important law of radioactivity is that of the exponential decay. In the realm of quantum mechanics, however, this decay law is neither rigorous nor fundamental.

The Extreme Learning Machine for the Extraction of Mono-Exponential Decay Time
The mono-exponential decay has been used to describe various physical phenomena such as cavity ring-down signal, fluorescence decay, etc. In this paper, a neural network method of extreme learning machine (ELM) is adopted to efficiently extract decay ...

It is well known, both theoretically and experimentally, that the survival probability for an unstable quantum state, formed at t=0, is not a simple exponential function, even if the latter is a good approximation for intermediate times.

Exponential Decay in the Sensitivity Analysis of Nonlinear Dynamic Programming [PDF]
In this paper, we study the sensitivity of discrete-time dynamic programs with nonlinear dynamics and objective to perturbations in the initial conditions and reference parameters. Under uniform controllability and boundedness assumptions for the problem

Cold Load Pickup Model Adequacy for Power System Restoration Studies
When a grid section is re-energized after an interruption, the load behaviour can be significantly different from normal operation. In this manuscript, the impact of the phenomenon—known as cold load pickup—is investigated by evaluating 31 time series ...

Moore-Gibson-Thompson thermoelasticity with two temperatures
In this note we propose the Moore-Gibson-Thompson heat conduction equation with two temperatures and prove the well posedness and the exponential decay of the solutions under suitable conditions on the constitutive parameters.

Linking the seroresponse to infection to within-host heterogeneity in antibody production
A recently published model for the serum antibody response to infection appeared well suited for use in statistical analyses of longitudinal serological data.

Analysis of an Epidemic Spreading Model with Exponential Decay Law
Mathematical modeling of infectious diseases has shown that combinations of isolation, quarantine, vaccine, and treatment are often necessary in order to eliminate most infectious diseases.
