Vision Research, 34, 1703-1721) have confirmed that searches for simple feature targets are not limited by perceptual processing capacity and the effect of set size on performance can be accounted for by integration stage processes only.

Palmer amaranth is resistant to several herbicides, including glyphosate, and there is concern that the resistance traits can be transferred between spatially segregated populations via pollen movement. The objective of this study was to describe the physical properties of Palmer amaranth pollen, specifically size, density, and settling velocity (Vs), that influence pollen flight. The mean diam...

Fluctuating asymmetry subtle random deviations from perfect bilateral symmetry ~ is an appealing measure of developmental precision because of the apparent ease with which it may be measured and because its developmental origins seem so straightforward (Palmer, 1996). This appeal has led to its wide application as a measure of developmental stability in studies of inbreeding and outbreeding dep...

modal verbs and their different meanings can be investigated on the basis of various theoretical frameworks. in this paper, persian modal verbs are examined and analyzed in terms of degrees and kinds of modality proposed by palmer (1990). our analysis shows that although bǎyad ‘must’ does not entail the proposition, it is used to express three degrees of epistemic modality, two degrees of dynam...
