Adaptive radiations were central to Darwin's formation of his theory of natural selection, and today they are still the centerpiece for many studies of adaptation and speciation. Here, we review the advantages of adaptive radiations, especially recent ones, for detecting evolutionary trends and the genetic dissection of adaptive traits. We focus on Aquilegia as a primary example of these advant...

The human visual system can resolve higher spatial frequencies in the fovea than in the periphery. This property has been harnessed by recent 2D foveated rendering methods to reduce computation cost while maintaining perceptual quality. Inspired by this, we have conducted psychophysical experiments to study foveation of human visual systems for 4D light fields and evaluate our prototype system ...

PURPOSE OF REVIEW The increase in obesity in developed societies drives interest in the interplay of energy intake, metabolic energy expenditure, and body energy stores. A better understanding of energy management in physically active and undernourished humans should help guide strategies to manage obesity safely and effectively. This review focuses on field studies of men and women engaged in ...

Field studies and user requirements analysis are highly valued practices in the human-computer interaction community. However, in companies, field study methods are not widely used and they still encounter resistance. In this paper, we describe a longitudinal research effort conducted in two companies to introduce field studies and make them a part of the product development process. A strategy...

This article examines the different failure modes of concrete sidewalks through an extensive field survey of sidewalk inventories in major cities in the Canadian Prairies. The major form of sidewalk damage is longitudinal cracks. There was no correlation of either the liquid limit or the plastic limit of the soil beneath the sidewalk with the type of sidewalk damage observed in each city. Howev...

Advanced INSAR techniques using stable targets on the ground, such as buildings, have been successfully applied to deformation studies in city areas. However, in some cases high-quality reference measurements have not been available and the validations of the INSAR results have been based on data that probably is not adequate for this purpose. In 2005 the Finnish Geodetic Institute (FGI) establ...
