Objective(s): Alternative normalization methods were proposed to solve the biased information of SPM in the study of neurodegenerative disease. The objective of this study was to determine the most suitable count normalization method for SPM analysis of a neurodegenerative disease based on the results of different count normalization methods applied on a prepared digital phantom similar to one ...

In quantitative real-time PCR, the mRNA level can be quantified in relative terms based on the expression ratio of mRNAs of the target gene and an internal reference gene. Since, an internal standard should be expressed at a constant level among different tissues of an organism at all stages of development, and should be unaffected by the experimental treatment, the stability of different refer...

Whether basal metabolic rate-body mass scaling relationships have a single exponent is highly discussed, and also the correct statistical model to establish relationships. Here, we aimed (1) to identify statistically best scaling models for 17 mammalian orders, Marsupialia, Eutheria and all mammals, and (2) thereby to prove whether correcting for differences in species' body temperature and the...

We propose a new algorithm for closed queueing networks and related product-form models based on numerical inversion of the generating function of the normalization constant (or partition function). It is known that the generating function of the normalization constant often has a remarkably simple form, but numerical inversion evidently has not been considered before. We also show that moments...

We review the application of differential operators of noninteger order to the modeling of dynamic systems. We compare all the definitions of Variable Order VO operators recently proposed in literature and select the VO operator that has the desirable property of continuous transition between integer and non-integer order derivatives. We use the selected VO operator to connect the meaning of fu...

The random waypoint model (RWP) is one of the most widely used mobility models in performance analysis of ad hoc networks. We analyze two key properties of the RWP model in a given convex area: the stationary spatial distribution for the location of the node and the mean length of a leg (line between two waypoints). A general expression is given for the spatial node distribution in the form of ...

A fundamental problem in speech perception is how (or whether) listeners accommodate variability the way talkers produce speech. One view of cope with this that talker differences are normalized – a mapping between talker-specific characteristics and phonetic categories computed such recognized context talker’s vocal characteristics. Consistent view, process more slowly when changes randomly th...
