We present a fitted model of sky dome radiance and attenuation for realistic terrestrial atmospheres. Using scatterer distribution data from atmospheric measurement data, our considerably improves on the visual realism existing analytical clear models, as well interactive methods that are based approximating light transport. also provide features not found in models so far: patterns post-sunset...

This paper derives the EDITRK4 technique, which is an exponentially fitted diagonally implicit RK method for solving ODEs . approach intended to integrate exactly initial value problems (IVPs), their solutions consist of linear combinations group functions and fitting problems, with being problem’s major frequency utilized improve precision method. The modified a new three-stage fourth-order ex...

Abstract Maximum likelihood fits to data can be done using binned data (histograms) and unbinned data. With binned data, one gets not only the fitted parameters but also a measure of the goodness of fit. With unbinned data, currently, the fitted parameters are obtained but no measure of goodness of fit is available. This remains, to date, an unsolved problem in statistics. Using Bayes theorem a...

Two endothelin (ET)-binding inhibitors, BE-18257A and BE-18257B, which antagonized 125I-ET-1 binding to a porcine aortic smooth muscle membrane, were isolated from the mycelium of a strain of Streptomyces misakiensis. These binding inhibitors were extracted with methanol from mycelium and purified by HPLC.

CONTEXT Proper management of cervical spine injuries in men's lacrosse players depends in part upon the ability of the helmet to immobilize the head. OBJECTIVE To determine if properly and improperly fitted lacrosse helmets provide adequate stabilization of the head in the spine-boarded athlete. DESIGN Crossover study. SETTING Sports medicine research laboratory. PATIENTS OR OTHER PARTI...
