advantage of the unique capabilities of the computer to teach. The self-test segment of the program is simply a memory game, which does not focus on clinically relevant anatomy or provide a framework on how to think radiologically. In summary, while The Imaging Atlas functions appropriately, it offers few advantages over a radiographic atlas in book form. A firm grasp of statistical distributio...

A nonparametric upper tolerance limit (UTL) bounds a specified percentage of the population distribution with specified confidence. The most common UTL is based on the largest order statistic (the maximum) where the number of samples required for a given confidence and coverage is easily derived for an infinitely large population. However, for other order statistics such as the second largest, ...

Infants' perception of speech sound contrasts is modulated by their language environment, for example by the statistical distributions of the speech sounds they hear. Infants learn to discriminate speech sounds better when their input contains a two-peaked frequency distribution of those speech sounds than when their input contains a one-peaked frequency distribution. Effects of frequency distr...

Electromigration is an important failure phenomenon in ULSI. There are several underlying physical mechanisms in an electromigration process depending on the stress conditions. In this work, we use various statistical techniques to investigate the number of such mechanisms for a given set of electromigration data. The statistical distribution of each mechanism can be found and the failure units...

The magnetic properties of molecule-based magnets are commonly rationalized by considering only a single nuclear configuration of the system under study (usually an X-ray crystal structure). Here, by means of a computational study, we compare the results obtained using such a static approach with those obtained by explicitly accounting for thermal fluctuations, and uncover the serious limitatio...

This paper suggests a method of evaluation of uncertainties in calculated transition probabilities by randomly varying parameters of an atomic code and comparing the results. A control code has been written to randomly vary the input parameters with a normal statistical distribution around initial values with a certain standard deviation. For this particular implementation, Cowan's suite of ato...

We investigate the statistical distribution of separation time DT between the adjacent two Barkhausen jumps in Co films having the thickness ranging from 5 to 50 nm. By means of a magneto-optical microscope magnetometer, we determine the time-dependent magnetization curve and the separation time DT between two jump events during avalanche process from the directly observed time-resolved domain ...

We show that the extinction of quasar absorbers increases exponentially with the logarithmic column density of any volatile metal (e.g. zinc), with a charateristic turning point above which the quasars are severely dimmed. We derive the relation between extinction, HI column density (NHI), metallicity (Z ≡ NZnII/NHI) and fraction of iron in dust [fFe(Z)] in Damped Lyman α (DLA) systems. We use ...

Ten different samples of lyophilized plasma and two of liquid urine were distributed during two years to 26 laboratories performing quantitative amino acid analyses in a scheme designed to provide external quality assessment. After each distribution, statistical summaries and performance scores based on delta standard deviations and percentage biases from the all-laboratory trimmed means were r...
