Please see COVER STORY next page When approaching the end of stage two in the Differential Straight-Arch® Technique, one has to make the decision whether to finish the case with round or r e c t a n g u l a r archwires. Continuing with round wires can simplify treatment for the operator—no need for more archwires. In other cases the use of r e c t a n g u l a r archwires can provide automatic t...

The diversification of the development in humancomputer interaction provides users more and more interactive experience which is totally different than usual. As one of the sense organs that serve as a proxy for human attention and intention, we can give users better interaction closer to their need by observing the change of the eyes. This paper proposes a low-cost system, using a non-infrared...

We generalize the multistage period search and analysis method for the case when the data error estimates (i.e. statistical weights) are available. Adjustment of model parameters allows us to detect complex wave forms in noisy data. Complementary statistical tests are also presented to estimate the significance of the detected periodicities, to verify the modelling reliability, and to separate ...

In regard to colored lights, an opponent cell will indeed increase its firing to luminance increments (as well as to equiluminant color increments) but this does not at all imply confounding; rathe, r, in both cases, the cell will signal more color. Alternatively stated, when one increases the luminance (or radiance, or energy, etc.) of a colored light, any theory must predict that its chromati...
