This paper describes the Utah State University (USU) entry in the 2002 robotic Urban Search and Rescue (USAR) competition, hosted by the American Association for Artificial Intelligence (AAAI). More importantly, it also describes the problems the team encountered in preparing for this year’s competition, the lessons learned, and plans for the 2003 USAR competition. Description of the 2002 Entry...

However brilliant a scientist is, however incisive their mind and however elegant their experiments, they must be able to communicate effectively. The ability to write fluently, to inspire an audience in a lecture hall, and to listen carefully and argue cogently face-to-face with a sceptic are all important. Maybe some people believe that it’s only important to impress the journal referees and ...

In the atrioventricular canal (AVC) and outflow tract (OT) of the developing heart, endothelial cells transform specifically to mesenchymal cells. The mesenchymal cells migrate into the underlying acellular matrix termed cardiac jelly and form endocardial cushion tissue. It is believed the that the highly hydrated nature of cardiac jelly is ascribed to sulfated glycoconjugates in the components...

Atmospheric parameters (Teff , log g), masses and helium abundances are derived for 42 hot horizontal branch (HB) stars in the globular cluster NGC 6752. For 19 stars we derive magnesium and iron abundances as well and find that iron is enriched by a factor of 50 on average with respect to the cluster abundance whereas the magnesium abundances are consistent with the cluster abundance. Radiatio...

Many substances have been examined (1, 2) as possible inhibitors of xanthine oxidase. Included among the more effective inhibitors are 2amino-4-hydroxy-6-pteridinecarboxaldehyde (hereafter referred to as 6pteridylaldehyde) (1, 3-7) and other pteridine derivatives (5, 6) ; chalcones such as 3,3’ ,4,4’-tetrahydroxychalcone (8, 7) ; cyanide (9-14); the quinimine or oxidized form of p-aminophenol (...

Two phase points (18 C.T. and 19 C.T.) in the subjective night of the Drosophila pseudoobscura circadian rhythm of eclosion, representing the end of the first half of the night and the beginning of the second half respectively, were exposed to blue (442 nm) light pulses of varying energies. The 18 C.T. phase was less sensitive relative to the 19 C.T. phase which is nearly 10-times as sensitive....

We report our analysis of a Chandra X-ray observation of the rich globular cluster M80, in which we detect some 19 sources to a limiting 0.5-2.5 keV X-ray luminosity of 7 × 10 ergs s within the half-mass radius. X-ray spectra indicate that two of these sources are quiescent low-mass X-ray binaries (qLMXBs) containing neutron stars. We identify five sources as probable cataclysmic variables (CVs...
