In this thesis we introduce alpha and beta tree acceptors,
generalizations of tree automata. The alpha tree acceptors recognize
a tree by final symbol and the beta tree acceptors by final state. We
show that alpha and beta tree acceptors recognize the same sets of
Gorn trees and demonstrate that...
The story of Leo Szilard has not been told in its full complexity. This is especially so of the role imagination played in Szilard’s worldview. Szilard, like many other scientists in the mid-twentieth century, worked on the Manhattan Project. Like these other wartime participants, the work and relationships formed during...
Soil pore size distribution and water characteristics are important for water storage, water movement, and soil-plant interaction studies. Laboratory determinations of water characteristics and pore size distribution are time consuming and costly. Investigators have proposed many models to predict them from routinely available data. Most of the models are related...

Ocean waves propagating over cohesionless seabed deposits
produce cyclic shear stresses within the deposit. Under certain
conditions these stresses may cause a progressive build-up of pore
pressure. Pore pressure accumulation can result in liquefaction or
a substantial decrease in the effective stress with attendant large
deformations of the seabed deposit....
Director David Fincher’s films contain many distinct elements that set his work apart, but one of the most instantly recognizable elements is his visual style – specifically, his camerawork. The level of control and purposefulness that Fincher exhibits in his films qualify Fincher as the auteur, or “author,” of his...
The regulation of ergosterol biosynthesis in yeast has been
studied. The system has been examined for the presence of an end-product inhibition. Both anaerobically and aerobically grown cells
have been examined for this effect. A feedback inhibition of sterol
synthesis has been shown, but it appears to be a secondary...
