Motion parallax, or differential retinal image motion from observer movement, provides important information for depth perception. We previously measured the contribution of shear motion parallax to depth, which is only composed of relative motion information. Here, we examine the roles of relative motion and accretion-deletion information in dynamic occlusion motion parallax. Observers perform...

Fourteen years have passed since Gifford’s seminal paper on weighted voting [7]. These years have seen the development of numerous protocols for managing replicated data and a handful of experimental systems implementing replicated files. The time has now come to attempt an inventory of the problems for which we have found solutions and the issues that remain open. One way to structure this inv...

Pathway enrichment analysis represents a key technique for analyzing high-throughput omic data, and it can help to link individual genes or proteins found to be differentially expressed under specific conditions to well-understood biological pathways. We present here a computational tool, SEAS, for pathway enrichment analysis over a given set of genes in a specified organism against the pathway...

Accurate identification of depth phases is essential in improving the performance of the event screening process. In the first Release of event screening software, the rules for depth phases were insufficient, in that events that had inappropriate depth phase picks could satisfy the depth phase criteria. To strengthen the depth phase criteria so there is more confidence in the results, a new se...

The spatial resolution of disparity perception is poor compared to luminance perception, yet we do not notice that depth edges are more blurry than luminance edges. Is this because the two cues are combined by the visual system? Subjects judged the locations of depth-defined or luminance-defined edges, which were separated by up to 5.6 min of arc. The perceived edge location was a function of t...

Seismic event location remains as one of the most important discriminants for separating natural tectonic and explosive events. However, in order to be useful for discrimination purposes, the uncertainties associated with seismic locations must be well defined and reliable, and this has proven to be difficult to accomplish to the required degree of accuracy. In particular, high-confidence estim...

Social communication relies on intentional control of emotional expression. Its variability across cultures suggests important roles for imitation in developing control over enactment of subtly different facial expressions and therefore skills in emotional communication. Both empathy and the imitation of an emotionally communicative expression may rely on a capacity to share both the experience...

Zoltan: Captain, since Org “enthusiastically landed” our ship, I have successfully repaired all our equipment except for the tricorders. While they are highly reliable in identifying which humans are pregnant, their compromised power supply won’t last until the planned abduction date. We are, therefore, evaluating other potential identification methods. We will use the tricorders as the gold st...

The benefits of binocular vision have been debated throughout the history of vision science yet few studies have considered its contribution beyond a viewing distance of a few meters. In the first set of experiments, we compared monocular and binocular performance on depth interval estimation and discrimination tasks at 4.5, 9.0 or 18.0 m. Under monocular conditions, perceived depth was signifi...
