Unlike the cells of many tissues, muscle and neuronal cells do not replicate throughout life. Therefore there has to be an eVective mechanism of inducing local repair and preventing cell death. We have identified and cloned two growth factors that are expressed by muscle when it is subjected to activity which are derived from the insulin like growth factor-I (IGF-I) gene by alternative splicing...

ABSTRACT This paper studies the performance of the unrestricted estimator (UE) and preliminary test estimator (PTE) of the slope parameter of simple linear regression model under linex loss function. The risk functions of both the UE and PTE are derived. The moment generating function (MGF) of the PTE is derived which turns out to be a component of the risk function. From the MGF the first two ...

We characterize the performance of energy detector (ED) over square-law, square-law selection, and switch-and-stay diversity combining schemes. The exact average probabilities of a miss (Pm), and a false alarm (P f ) are derived in closed-form. To derive Pm for versatile Nakagami-m and Rician fading channels, a twofold approach, using the probability density function (PDF) and the moment genera...

4Ve describe the exact statistics of an optically preamplified direct detection receiver by means of the moment generating function. The theory allows an arbitrary shaped electrical filter in the receiver circuit. The moment generating function (MGF) allows for a precise calculation of the error rate by using the inverse Fast Fourier transform (FFT). The exact results are compared with the usua...

In this article we apply two distinct methods to obtain simple closed-form approximations for the average symbol error rate (ASER) performance metric of a broad class of coherent digital modulations in a myriad of fading environments, which are known to be analytically involved as they require evaluation of the expectation of the Gaussian Qfunction and/or its integer powers. In the first approa...

The cumulative distribution function (cdf) and the moment generating function (mgf) of a linear sum of ordered random variables (RVs) are needed for characterizing the performance of a generalized selection combining (GSC) receiver. Unfortunately, in all but a few cases, the mgf and the cdf either are not in closed form or exist only as multidimensional integrals. Consequently, analyzing the GS...

Using a circular contour integral representation for the generalized Marcum-Q function, ( ), we derive a new closed-form formula for the moment generating function (MGF) of the output signal power of a dual-diversity selection combiner (SC) in bivariate (correlated) Nakagamifading with positive integer fading severity index. This result involves only elementary functions and holds for any value...
