when we examined sections from our control birds we saw something very striking. The hippocampus was clearly much larger in chickadees than shown in the atlas. Where the canary atlas showed a smooth curve as the dorsal surface of the brain travelled medially and descended between the hemispheres, the chickadees had a large bump. Previous work by many researchers on the songbird brain had prepar...

Many different formats exist for storing different types of images. Photographs of natural scenes usually are best suited to be stored as Raster images. But drawings are better off if stored as Vector graphics. Some formats can even store both types of images, but none of the existing formats can change itself to adopt a balance between both methods, based on the content of the image. This proj...

Planning for manufacturing workpieces is a complex task that requires the interaction of a domain-speciic reasoner and a generic planning mechanism. In this paper we present an architecture for organizing the case base that is based on the information provided by a generic problem solver. A retrieval procedure is then presented that uses the information provided by the domain-speciic reasoner i...

Today, the overwhelming volume of information that is available to an increasingly wider spectrum of users creates the need for personalization. In this paper, we consider a database system that supports context-aware preference queries, that is, preference queries whose result depends on the context at the time of their submission. We use data cubes to store the associations between context-de...

The purpose of the paper is to examine the nature of chemical concepts, and the ways in which they are applied in chemoinformatics systems. An account of concepts in philosophy and in the information sciences leads to an analysis of chemical concepts, and their representation. The way in which concepts are applied in systems for information retrieval and for structure–property correlation are r...

Climate science requires the analysis of variables such as temperature, precipitation, and ozone concentration, which depend on multiple dimensions, mainly time, latitude, longitude, and height/depth, and are commonly stored in the NetCDF file format. Various infrastructure has evolved around this format such as libraries, command line tools, visualization software, and web services. In this wo...

Oxidase test reagents are notoriously unstable, but they can be held ready for use if frozen or if reagent-impregnated filter paper is kept dry.
