By using the usual additive neural-network model, a delay-independent stability criterion for neural dynamics with perturbations of time-varying delays is derived. We extend previously known results obtained by Gopalsamy and He (1994) to the time varying delay case, and present decay estimates of...
This paper presents an alternative and straightforward two-step estimation method for the Nelson鈥揝iegel yield curve model. The goal is to generate smoothed time series for the time-varying decay parameter and establish stable yield curve factors. To rectify excessive parameter estimates such as ...
We study dynamic interplay between time-delay and velocity alignment in the ensemble of Cucker-Smale (C-S) particles(or agents) on time-varying networks which are modeled by digraphs containing spanning trees. Time-delayed dynamical systems often appear in mathematical models from biology and control...
Thus, this shift would make the upper potential of oscillations higher, leading to a faster surface activation process, favoring a fast decay to low potential values. In 2005, Okamoto and coworkers54 investigated the common aspects in the oscillatory electrooxidation of formic acid, methanol, and ...
Transmission of a Gaussian source over a time-varying Gaussian channel is studied in the presence of time-varying correlated side information at the receiver. A block fading model is considered for both the channel and the side information, whose states are assumed to be known only at the recei...
(TCSPC) has the advantage over the aforementioned techniques in being the most photon efficient method for FLIM18,19,20,21,22,23. It also performs a direct and accurate measurement of the fluorescence decay shape. TCSPC-based FLIM is typically done with single-point detectors, which require ...
I.1.1). Such signals are described as time-varying or nonstationary because their frequency content varies with time. In Fig. I.1.1, the time-domain representation (a) does not clearly show what frequencies are present, and the frequency-domain representation (b) does not show when they are...
While we focus on varying the extinction rate only, our approach is applicable to any reaction rate in a Doi–Peliti field theory. Neuronal avalanches can show oscillating behaviour, which we capture with a branching process model with oscillating extinction rate. These oscillations can be observed...
The problem of estimating the parameters of a Poisson-Gaussian model from experimental data has recently raised much interest in various applications, for instance in confocal fluorescence microscopy. In this context, a field of independent random variables is observed, which is varying both in time ...
GENERAL DECAY RATE ESTIMATE FOR THE ENERGY OF A WEAK VISCOELASTIC EQUATION WITH AN INTERNAL TIME-VARYING DELAY TERM In this paper we consider the weak viscoelastic equation with an internal time-varying delay term $$u_{tt}(x,t)-\\\Delta u(x,t)+\\\alpha(t)\\\int_{0}^{t... W Li...
