We develop a new algorithm for interferometric SAR phase unwrapping based on the rst Green's identity with the Green's function representing a series in the eigenfunctions of the two-dimensional Helmholtz homogeneous diierential equation. This provides closed-form solutions using one-or two-dimensional fast Fourier transforms. The algorithm is elaborated using adaptive regularization of the int...

Saccadic eye movements produce transient distortions in both space and time. Mounting evidence suggests that space and time perception are linked, and associated with the perception of another important perceptual attribute, numerosity. Here we investigate the effect of saccades on the perceived numerosity of briefly presented arrays of visual elements. We report a systematic underestimation of...

Feature search studies typically address the speed and accuracy of identifying a target item while dismissing attention focused on distractors. In the studies presented here, the level of attention focused on distractors is measured in a feature search task by occasionally asking participants how many items appeared in the search display. Results show some awareness for number of distractors; h...

The assessment of collective risk for flood risk management requires a better understanding of the space-time characteristics of flood magnitude and occurrence. In particular, classic formulation of collective risk implies hypotheses concerning the independence of intensity and number of events over fixed time windows that are unlikely to be tenable in real-world hydroclimatic processes exhibit...

A common interpretation of genome-wide selection scans is that the dispersal of anatomically modern humans out of Africa and into diverse environments led to a number of genetic adaptations. If so, patterns of polymorphism from non-African individuals should show the signature of adaptations dating to 40,000-100,000 Kya, coinciding with the main exodus from Africa. However, scans of polymorphis...

We quantitatively examined the difference in perceived size between upright and inverted faces using the method of constant stimuli. The stimuli included eight face images modified from two cartoon faces produced by Kitaoka (2007, http://www.psy.ritsumei.ac.jp/-akitaoka/kao-e.html and 2008, Cognitive Psychology 5 177-185) and six photographic faces, including a photographic face used by Thompso...
