Modeling and Assessment of Long Afterglow Decay Curves
The Scientific World Journal, 2014 Multiple exponential equations have been successfully fitted to experimental long afterglow decay curve data for some phosphor materials by previous researchers.

International Journal of Adaptive Control and Signal Processing, EarlyView.This paper proposes two projector‐based Hopfield neural network (HNN) estimators for online, constrained parameter estimation under time‐varying data, additive disturbances, and slowly drifting physical parameters. The first is a constraint‐aware HNN that enforces linear equalities and inequalities (via slack neurons) and continuously tracks the ...

Photocounting distributions for exponentially decaying sources [PDF]
Optics Letters, 1979 Exact photocounting distributions are obtained for a pulse of light whose intensity is exponentially decaying in time, when the underlying photon statistics are Poisson. It is assumed that the starting time for the sampling interval (which is of arbitrary duration) is uniformly distributed. The probability of registering n counts in the fixed time T is

Bath-induced decay of Stark many-body localization
, 2019 We investigate the relaxation dynamics of an interacting Stark-localized system coupled to a dephasing bath, and compare its behavior to the conventional disorder-induced many body localized system.

Advanced Biology, EarlyView.Infrared (IR) light evokes distinct calcium and water transport responses in astrocytes, depending on stimulation duration and protocol. This study uses widefield imaging and pharmacology to reveal differential engagement of astroglial signaling pathways.

Exponential decay of Lebesgue numbers
Discrete and Continuous Dynamical Systems, 2012 We study the exponential rate of decay of Lebesgue numbers of open covers in topological dynamical systems. We show that topological entropy is bounded by this rate multiplied by dimension. Some corollaries and examples are discussed.

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Decay of Strong Solutions for 4D Navier-Stokes Equations Posed on Lipschitz Domains
Advances in Mathematical Physics, 2018 Initial-boundary value problems for 4D Navier-Stokes equations posed on bounded and unbounded 4D parallelepipeds were considered. The existence and uniqueness of regular global solutions on bounded parallelepipeds and their exponential decay as well as ...

An improved test of the exponential decay law [PDF]
Physics Letters B, 1995 Abstract We have compared the decay rate of freshly prepared 40K to that of 40K that is >4.5 × 109 years old. We find that to within the experimental uncertainly of ± 11%, the decay rates are the same. This indicates that the exponential nature of the decay law is valid down to time-scales of approximately 10 −10 t 1 2 .

Exponential Decay of Correlations Implies Area Law
, 2015 We prove that a finite correlation length, i.e. exponential decay of correlations, implies an area law for the entanglement entropy of quantum states defined on a line.
