We analyze the locomotor behavior of the rat during exploration, and show that digitally collected data (time series of positions) provide a sufficient basis for establishing that the rat uses several distinct modes of motion (first, second, third, and sometimes fourth gear). The distinction between these modes is obtained by first segmenting the time series into sequences of data points occurr...

This article investigates the synaptic weight distribution of a self-supervised, sparse, and randomly connected recurrent network inspired by hippocampal region CA3. This network solves nontrivial sequence prediction problems by creating, on a neuron-by-neuron basis, special patterns of cell firing called local context units. These specialized patterns of cell firing--possibly an analog of hipp...

Introduction The NIfTI-1 image format (http://nifti.nimh.nih.gov/dfwg) contains a field intent code which signals the interpretation of the data values in the file. A number of codes are defined that correspond to standard statistical distributions. My goal in this document is to specify what these codes refer to, and also to document the user-level sample C functions provided at the NIfTI webs...

This paper deals with the classical problem of how to evaluate the joint rank statistics distributions for two independent i.i.d. samples from a common continuous distribution. It is pointed that these distributions rely on an underlying polynomial structure of negative binomial type. This property is exploited to obtain, in a systematic and unified way, various recursions, some well estabished...

< A statistical model is developed for estimating GDL thermal conductivity. < The model considers the statistical distribution of GDL geometrical parameters. < Angle and aspect ratio distributions are measured for some GDLs. < The dependency of thermal conductivity on geometrical parameters is considered. < New techniques are introduced for GDL geometrical property measurements. a r t i c l e i...

Absf~act We compare the methods of Cohen and 2. REVIEW OF THE TWO METHODS of Baraniuk and Jones-for obtaining joint distributions for arbitrary variables. We show that the two methods produce identical results for variables whose associated operators are obtained via a unitary transformation of the time and frequency operators. In addition, we generalize this result and show that all pairs of v...

The amplitude and pitch fluctuations of natural soundscapes often exhibit "1/f spectra", which means that large, abrupt changes in pitch or loudness occur proportionally less frequently in nature than gentle, gradual fluctuations. Furthermore, human listeners reportedly prefer 1/f distributed random melodies to melodies with faster (1/f0) or slower (1/f2) dynamics. One might therefore suspect t...

The long-term goal of the present high-frequency scattering statistics work is to examine the links between environmental parameters of shallow water boundaries and the statistics of high frequency, broadband acoustic fields using a combination of at-sea measurements, ground truth and theoretical modeling. The influence of the properties of the boundaries to the scattered envelope statistics an...

In this article we emphasize the manner in which this statistical indicator the variation coefficient (v) could help the inference on measurable characteristics generated by technological processes. Our interest lies upon the so-called SPCStatistical Process Control; the main result obtained is the following: if the coefficient of variation is known, then the statistical distribution of capabil...

We present research in progress, aimed at explaining the tradeoffs between vegetative and reproductive structures in the architecture of Protea. The species of interest, Protea lepido-carpodendron, reproduces only after a fire that kills it. We aim at using a biomechanical developmental functionalstructural model to demonstrate that Protea lepidocarpodendron is adapted to the statistical distri...
