We consider $$\displaystyle \begin{aligned} \left\{ \begin{array}{rl} & \partial_t^{\alpha} (u-a) + A(t)u(x,t) = 0 \quad \mbox{in }L^2(\Omega), \, 0 < t < T, \\ & u(\cdot,t) \in H^1_0(\Omega), \quad 0 < t < T, \\ & u-a \in H_{\alpha}(0,T;L^2(\Omega)). \end{array}\right.

Rate of Decay of Auditory Sensation
The Journal of the Acoustical Society of America, 1964The rate of decay of auditory sensation was investigated by measuring the minimum silent interval that must be introduced between two noise pulses to be perceived. The value of this critical time Ît was determined for different intensity levels of both the first and the second pulse. It is shown that in this case the sensation level of the second pulse

In this paper we briefly review all positronium (Ps) decay rate measurements (including those of the excited states and the Ps negative ion) that have been completed to date. The results are compared with theoretical values. The Ps system represents the most rigorous confrontation with theoretical decay rate calculations for any QED system.

Impact of mobility on trust decay rate
2012 IEEE Wireless Communications and Networking Conference (WCNC), 2012In trust-based models for MANETs, it is often assumed that the trust value between two nodes decays proportional to the time these nodes are out of transmission range of each other. We present in this paper an analysis of the trust decay rate for some general networking and trust computation models.

The pionic two-body decay amplitude of the proton in the SU(5) grand unified gauge theory is computed by using the soft-pion method in the reference frame of the pion at rest. The normalization condition of the relativistic three-body Bethe-Salpeter wave function of the proton is used in the computation.

Decay Rates of Different mRNA in E. coli and Models of Decay
Nature New Biology, 1972THE basis for messenger RNA instability in bacteria is not understood. Both functional capacity1,2 and mass of messages for a given protein are lost at constant exponential rates which can differ, indicating independent processes3.

Measurement of the rate for pion beta decay
Physical Review D, 1985The conserved-vector-current hypothesis, together with measured nuclear beta-decay rates, predicts a value of the rate for the decay ..pi../sup +/..--> pi../sup 0/e/sup +/..nu.. of 0.4027 +- 0.0018 s/sup -1/. Using a decay-in-flight technique we have made the most precise measurement to date of this rate, obtaining the value 0.394 +- 0.015 s/sup -1 ...

A simple estimator for frequency and decay rate
IEEE Transactions on Signal Processing, 1996A simple, computationally inexpensive algorithm is developed for estimating the frequency and decay rate of a complex exponential. Two iterations of the algorithm attains the Cramer-Rao bound on the variance of the frequency and decay rate estimate for a complex exponential in white Gaussian noise. The algorithm uses an adaptive window that changes its

The new decay rates of mesons which have been published within the last year are examined to determine their consistency with SU(3) symmetry, vector dominance, and the quark model. It is shown that despite an apparent overall trend of the new data to disagree with certain quark-model predictions by a factor of 3 or so, the consistency of the data with ...
