In order to work in a consistent way with Zernike aberration coefficients estimated in different pupils, it is necessary to refer them to a common pupil size. Two standard approaches can be used to that end: to rescale algebraically the coefficients estimated in the original pupil or to refit them ...

Huber Stefan S Knowledge Media Research Center, Tuebingen Germany ; Department of Psychology, Eberhard Karls University, Tuebingen   2014
Decimal fractions comply with the base10 notational system of natural Arabic numbers. Nevertheless, recent research suggested that decimal fractions may be represented differently than natural numbers because two number processing effects (i.e., semantic interference and compatibility effects) differed in their size between decimal fractions and natural numbers. In the present ...

The dualsource ShuttleworthWallace model has been widely used to estimate and partition crop evapotranspiration (λET). Canopy stomatal conductance (Gsc), an essential parameter of the model, is often calculated by scaling up leaf stomatal conductance, considering the canopy as one single leaf in a socalled "bigleaf" model. However, Gsc can be ...

The classic understanding of prehension is that of coordinated reaching and grasping. An alternative view is that the grasping in prehension emerges from independently controlled individual digit movements (the doublepointing model). The current study tested this latter model in bimanual prehension: participants had to grasp an object between their two ...
