to urban environmental science, cities have been probed and analyzed from the partial …

Watts and Strogatz, with the publication in 1998 of their seminal paper on small-world
networks, opened the golden era of complex networks studies and showed in particular how …

Cities and their transportation systems become increasingly complex and multimodal as

As any cognitive task, visual search involves a number of underlying processes that cannot
be directly observed and measured. In this way, the movement of the eyes certainly …

To survive and pass on their genes, animals must perform many tasks that affect their fitness,
such as mate-choice, foraging, and predator avoidance. The ability to make rapid decisions …

Data sampled at discrete times appears as a succession of discontinuous jumps, even if the
underlying trajectory is continuous. We analytically derive a criterion that allows one to …

Whether hiding from predators, or avoiding battlefield casualties, camouflage is widely
employed to prevent detection. Disruptive coloration is a seemingly well-known camouflage …

Reading is a complex cognitive process that involves primary oculomotor function and high-
level activities like attention focus and language processing. When we read, our eyes move …

Edge detection is important for object detection and recognition. However, we do not know
whether edge statistics accurately predict the detection of prey by potential predators. This is …
