Hyperactive boys on methylphenidate (Ritalin), hyperactive boys on placebo, and comparison boys were observed in quasi-naturalistic classroom settings. Ambient stimulation (quiet versus noisy conditions) and source of regulation (self-paced versus other-paced activities) were varied in a 2 x 2 design. Compared to their peers, hyperactive boys on placebo(More)
Hyperactive and comparison boys participated in 5-week summer enrichment programs that included classroom activities and structured assessments of peer interaction patterns. During the 3rd and 4th weeks of these programs, a double-blind, methylphenidate-placebo crossover design was implemented within the hyperactive group. Three heterogeneous indicators of(More)
This paper describes a model of three-dimensional cellular automata allowing to simulate different phenomena in the fields of computer graphics and image processing, and to combine them together in order to produce complex effects such as automatic multitexturing, surface imperfections, or biological retina multi-layer cellular behaviours. Our cellular(More)
The Coulomb gap observed in tunneling between parallel two-dimensional electron systems, each at half-filling of the lowest Landau level, is found to depend sensitively on the presence of an in-plane magnetic field. Especially at low electron density, the width of the Coulomb gap at first increases sharply with in-plane field, but then abruptly levels off.(More)
