Localizing the sources of stimuli is essential. Most organisms cannot eat, mate, or escape
without knowing where the relevant stimuli originate. For many, if not most, animals, olfaction …

Planar laser-induced fluorescence (PLIF) is a non-intrusive technique for measuring scalar
concentrations in fluid flows. A fluorescent dye is used as a scalar proxy, and local …

The evolution of flowering plants has undoubtedly been influenced by a pollinator's ability to
learn to associate floral signals with food. Here, we address the question of 'why'flowers …

Animals travelling through the world receive input from multiple sensory modalities that
could be important for the guidance of their journeys. Given the availability of a rich array of …

Odor attraction in walking Drosophila melanogaster is commonly used to relate neural
function to behavior, but the algorithms underlying attraction are unclear. Here, we develop …

This paper addresses the problem of estimating a likelihood map for the location of the
source of a chemical plume using an autonomous vehicle as a sensor probe in a fluid flow …

In this paper, we first draw a connection between a level set algorithm and k-Means plus
nonlinear diffusion preprocessing. Then, we exploit this link to develop a new hybrid …

Using odors to find food and mates is one of the most ancient and highly conserved
behaviors. Arthropods from flies to moths to crabs use broadly similar strategies to navigate …

The acquisition of information from sensory systems is critical in mediating many ecological
interactions. Chemosensory signals are predominantly used as sources of information about …

Many arthropods capture odorant molecules from the environment using antennae or
antennules bearing arrays of chemosensory hairs. The penetration of odorant-carrying water …
