To provide a behavior-based estimate of odor similarity in larval Drosophila, we use 4 recognition-type experiments: 1) We train larvae to associate an odor with food and then test whether they would regard another odor as the same as the trained one. 2) We train larvae to associate an odor with food and test whether they prefer the trained odor against a(More)

The Wuerzburg Hybridoma Library against the Drosophila brain represents a collection of around 200 monoclonal antibodies that bind to specific structures in the Drosophila brain. Here we describe the immunohistochemical staining patterns, the Western blot signals of one- and two-dimensional electrophoretic separation, and the mass spectrometric(More)
Similarity between odours is notoriously difficult to measure. Widely used behavioural approaches in insect olfaction research are cross-adaptation, masking, as well as associative tasks based on olfactory learning and the subsequent testing for how specific the established memory is. A concern with such memory-based approaches is that the learning process(More)
This paper presents a user-friendly display, in a ten-by-eight matrix format, of a collection of 80 univariate distributions and their interrelationships. A simplified five-by-five matrix, showing only 25 families, is designed for student use. These relationships provide rapid access to information that must otherwise be found through a time-consuming(More)
The objective of this study was to investigate the effect of inpatient boarding on the degree of Emergency Department (ED) overcrowding. We developed a discrete-event simulation (DES) approach to model ED patient flow based on a census of 26,984 patients from January through May, 2008. We modeled the Emergency Department of the University of California,(More)
