Nondimensionalized equations of motion for waterdrops, not necessarily obeying Stokes's
law, are derived and used to calculate the response of various size drops to changes in horizontal
wind speed. We find that (1) cloud drops respond almost instantaneously to changes
in wind speed, whereas raindrops require considerable time to adjust,...
We examined Goslin et al.’s (2012) claim that the object based-correspondence effect (faster keypress responses when the orientation of an object’s graspable part corresponds with the response location than when it does not) is the result of object-based attention (visual-action
binding). In Experiment 1, participants determined the category of a...
Tipper, Paul, and Hayes (2006) found object-based correspondence effects for door-handle stimuli for shape judgments but not color. They reasoned that a grasping affordance is activated when judging dimensions related to a grasping action (shape), but not for other dimensions (color). Cho and Proctor (2011, 2013), however, found the effect...
A major focus in macroecology is to understand the mechanisms that drive differences in habitat, morphology, and behavior in closely related species (Brown 1995). Within this paradigm, energy use and prey acquisition play a fundamental role in affecting behavior, especially with respect to foraging patterns and predator‐prey interactions. Because resources...
The detection and determination of clusters has been of special interest among researchers from different fields for a long time. In particular, assessing whether the clusters are significant is a question that has been asked by a number of experimenters. In Fuentes and Casella (2009), the authors put forth a...
Accurate estimation of historical abundance provides an essential baseline for judging the recovery of the great whales. This is particularly challenging for whales hunted prior to twentieth century modern whaling, as population-level catch records are often incomplete. Assessments of whale recovery using pre-modern exploitation indices are therefore rare, despite the...
An abundant fruiting of a black morel was encountered in temperate northwestern New South Wales (NSW), Australia, during a mycological survey in Sep 2010. The site was west of the Great Dividing Range in a young, dry sclerophyll forest dominated by Eucalyptus and Callitris north of Coonabarabran in an area...
Oceanic iron (Fe) fertilization experiments have advanced the understanding of how Fe regulates biological productivity and air–sea carbon dioxide (CO₂) exchange. However, little is known about the production and consumption of halocarbons and other gases as a result of Fe addition. Besides metabolizing inorganic carbon, marine microorganisms produce and consume...
For each Cantor set C in R³, all points of which have bounded local genus, we show that there are infinitely many inequivalent Cantor sets in R³ with the complement having the same fundamental group as the complement of C. This answers a question from Open Problems in Topology and...
Hexagonal AMO₂ and AMO₃ phases have the same basic structure, and intermediate compositions for this structure have been prepared by topotactic oxidation of AMO₂ phases such as RCuO₂, where R is a trivalent rare earth cation. We now find that such intermediate phases can also be prepared by topotactic reduction...
