In a previous study, N. Cherbuin and C. Brinkman (2006) showed that in right-handed participants, interhemispheric transfer time (measured with A. T. Poffenberger's, 1912, paradigm) was a significant predictor of the efficiency of hemispheric interactions (measured with a split visual field, letter-matching task). No effect was found for degree of handedness in this study. This was surprising because handedness has been shown to be associated with differences in the morphology and the structure of the corpus callosum, and cerebral anatomical lateralization, as well as functional lateralization both in behavioral and scanning studies. Because these findings were found in a large sample, but one limited to right-handed participants, the aim of the present study was to determine whether a similar relationship was present between interhemispheric transfer time and hemispheric interaction in left-handed participants (using identical measures) and to assess whether the analysis of a larger sample that comprised both left- and right-handed participants might reveal an effect of handedness. Results demonstrate significant handedness effects, suggesting that left-handed individuals tend to have more efficient hemispheric interactions.

Selective flocculation of iron oxide-kaolin mixtures using a modified polyacrylamide flocculant 总被引:1,自引:0,他引:1

High molecular weight polyacrylamides were synthesized and successfully modified to contain up to 8·3% hydroxamate functional
groups. The selective flocculation tests carried out on 1:1 iron oxide/kaolin mixtures using parent polyacrylamide, polyacrylic
acid and the modified polyacrylamide, confirm the possibility of enhancing selectivity through introduction of iron chelating
functional groups in commercially available polymers. Starting with a feed grade of 35% iron, 92% recovery with acceptable
grade of 60% iron has been achieved using the modified polyacrylamide.

In the present article, some special semantic integrity constraints—so called nondeterministic dependencies—are proposed. These dependencies can be regarded as stochastic extensions of functional dependencies. After some basic definitions, the concept of nondeterministic dependency is introduced. Examples are given and an implementation for a statistical analysis system is described. Some properties are discussed. 相似文献

The development of a solution method and computer program for the evaluation of multiarea reliability is reported. An interconnected power system is modelled as a capacitated network with probabilistic arc capacities. The proposed solution method consists of an analytic state space decomposition phase and a Monte-Carlo simulation phase. An optimization problem is solved to minimize the total computational time for the two phases. The solution of the optimal mix problem determines the termination of the decomposition phase and the size of sample for the Monte-Carlo phase. A new reliability index, the inadequate transfer capability, is introduced. This measure indicates the relative effectiveness of either increasing existing capacities or opening new interconnections between two areas. The proposed method has been incorporated into a computationally efficient production grade software package, called Remain (Reliability Evaluation of Multiarea Interconnections). The application of Remain to a seven-area example for planning-system enhancement is given. Computational-times data is also presented. 相似文献
