Objectives: The aim of the study was to examine whether the postpsychotic decline in IQ during schizophrenia coincides with psychopathological deterioration or it is a state-independent premorbid impairment. Methods: The IQ score of 32 schizophrenic patien ...
The relative basicities of aryllithiums bearing methoxy, chlorine, fluorine, trifluoromethyl and trifluoromethoxy substituents at the ortho, meta, and para positions have been assessed. To this end, two aryllithiums of comparable basicity were equilibrated ...
The contribution of the solvation energies to the assembly of polynuclear helicates reduces the free energy of intermetallic repulsion, DEMM, in condensed phase to such an extent that stable D3-symmetrical tetranuclear lanthanide-containing triplestranded ...
Most theories of visual masking focus primarily on the temporal aspects of visual information processing, strongly neglecting spatial factors. In recent years, however, we have shown that this position is not tenable. Spatial aspects cannot be neglected in ...
Visual backward masking is a commonly used technique in vision research and psychology. There are two distinct types of masking. Either masking is strongest for a simultaneous presentation of the target and the mask (A-type masking) or masking is strongest ...

We present high frequency Electron Spin Resonance (ESR) results on a peapod sample. In a previous low frequency ESR study on peapods and double-walled nanotubes the observation of a non-Lorentzian line shape was reported. This effect was tentatively attrib ...
Dynamic textures are sequences of images showing temporal regularity, such as smoke, flames, flowing water, or moving grass. Despite being a multidimensional signal, existing models reshape the dynamic texture into a 2D signal for analysis. In this article ...
The search for external knowledge must necessarily be accompanied by effective organizational learning. The effectiveness of learning is dependent on quite dissimilar factors based on whether the learning objective is explorative or exploitative. Moreover, ...
