Henderson Island’s Plastic: An Explanation

New species of Latreillopsis Henderson, 1888 (Brachyura: Homolidae) and Neopalicus Moosa & Serène, 1981 (Brachyura: Palicidae) from the Hawaiian Islands.

Two new species of brachyuran crabs belonging to Latreillopsis Henderson, 1888 (Homolidae) and Neopalicus Moosa & Serène, 1981 (Palicidae) respectively are described from Maui, Hawai'i. The new species of Latreillopsis is distinguished from its nine congeners by a granular carapace and pereopods, a triangular G1, and by the distinctive ornamentation of its carapace and third maxillipeds; the ne...

An Explanation of Splaying

Just as in bottom-up splaying, the idea is to follow each access by a restructuring of the search tree along the path from the accessed item to the root of the tree. The restructuring is done in a local fashion, i.e., without using information about the global structure of the tree. We call the restructuring algorithm the super̈ isor; it operates with a set of rules called the ruleset. Each unit...

An epistatic explanation

Interactions between two gene variants that rarely cause midline craniosynostosis on their own make the development of the disorder a certainty.

An empirical explanation of brightness.

In this second part of our study on the mechanism of perceived brightness, we explore the effects of manipulating three-dimensional geometry. The additional scenes portrayed here demonstrate that the same luminance profile can elicit different sensations of brightness as a function of how the objects in the scene are arranged in space. This further evidence confirms the implication of the scene...
