An exponential decay model for mediation. [PDF]
Prev Sci, 2014 Mediation analysis is often used to investigate mechanisms of change in prevention research. Results finding mediation are strengthened when longitudinal data are used because of the need for temporal precedence. Current longitudinal mediation models have focused mainly on linear change, but many variables in prevention change nonlinearly across time ...

Modeling the antidepressant treatment response to transcranial magnetic stimulation using an exponential decay function [PDF]
Scientific Reports, 2023 Recovery from depression often demonstrates a nonlinear pattern of treatment response, where the largest reduction in symptoms is observed early followed by smaller improvements.

Exponential decay of mutual information for Gibbs states of local Hamiltonians [PDF]
Quantum, 2022 The thermal equilibrium properties of physical systems can be described using Gibbs states. It is therefore of great interest to know when such states allow for an easy description.

Beyond Exponential Decay: How Biphasic and Delayed Decay Dynamics Shape Marine eDNA Dispersal [PDF]
Ecology and EvolutionAccurate interpretation of marine environmental DNA (eDNA) monitoring surveys depends on understanding how eDNA concentrations change once released by organisms into the surrounding environment.

The emptiness formation probability correlation in homogeneous and dimerized XX chains [PDF]
Condensed Matter Physics, 2009 We review some known properties of the "emptiness formation probability" correlation which we have calculated numerically for spin-1/2 XX chains with constant (homogeneous) or alternating (dimerized) nearest-neighbor coupling and an external field (in z ...

Exponential Decay of Sensitivity in Graph-Structured Nonlinear Programs [PDF]
SIAM Journal on Optimization, 2021 We study solution sensitivity for nonlinear programs (NLPs) whose structure is induced by a graph $\mathcal{G}=(\mathcal{V},\mathcal{E})$. These graph-structured NLPs arise in many applications such as dynamic optimization, stochastic optimization ...

A study of fractional order Ambartsumian equation involving exponential decay kernel
AIMS Mathematics, 2021 : 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
Physical Review Research, 2023 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.
