Long-Wavelength Modes of Cosmological Scalar Fields

We give a numerical analysis of long-wavelength modes in the WKB approximation of cosmological scalar fields coupled to gravity via $\xi\phi^{2}R$. Massless fields are coupled conformally at $\xi=1/6$. Conformality can be preserved for fields of nonzero mass by shifting $\xi$. We discuss implications for density perturbations.Comment: 10 pages, 10 figures, several stylistic improvement

Wind and the Machine

A single movement work for concert band, The Wind and The Machine draws upon Charles Ives and Igor Stravinsky for inspiration and formulaic process. Just as Ives uses in his Violin Sonata No. 3, The Wind and The Machine uses cumulative setting, a form that begins with the development of the theme and does not state the theme in full until near the end. Stravinsky\u27s Symphonies of Wind Instruments is used for formulaic and orchestrational ideas. The Wind and The Machine uses a recording made outside during a windy day at a busy intersection to dictate form and from which melodic and percussive ideas are drawn. The Wind and the Machine also makes use of counterpoint and ostinatos to create climactic events, much in the way of Ives. Thematic material is taken from songs written by the composer\u27s grandfather emulating Ives in the use of previously existing material

Towards a generic autonomic architecture for legacy resource management

Half a decade has passed since the objectives and benefits of autonomic computing were stated, yet even the latest system designs and deployments exhibit only limited and isolated elements of autonomic functionality. From an autonomic computing standpoint, all computing systems – old, new or under development – are legacy systems, and will continue to be so for some time to come. In this paper, we propose a generic architecture for developing fully-fledged autonomic systems out of legacy, non-autonomic components, and we investigate how existing technologies can be used to implement this architecture

A Classification and Analysis of Higgs-flavor Models

A classification is given of Higgs-flavor models. In these models, there are several Higgs doublets in an irreducible multiplet R_{Phi} of a non-abelian symmetry G_{Phi}, under which the quarks and leptons do not transform (thus giving minimal flavor-changing for the fermions). It is found that different G_{Phi} and R_{Phi} lead to very distinctive spectra of the extra Higgs doublets, including different numbers of "sequential Higgs" and of "inert Higgs" that could play the role of dark matter, different mass relations, and different patterns of SU(2)_L-breaking splittings within the Higgs doublets.Comment: 35 page

Quartification with T' Flavor

In the simplest (non-quiver) unified theories, fermion families are often treated sequentially and a flavor symmetry may act similarly. As an alternative with non-sequential flavor symmetry, we consider a model based on the group (T'*Z_2)_global * [SU(3)^4]_local which combines the predictions of T' flavor symmetry with the features of a unified quiver gauge theory. The model accommodates the relationships between mixing angles separately for neutrinos, and for quarks, which have been previously predicted with T'. This quiver unification theory makes predictions of several additional gauge bosons and bifundamental fermions at the TeV scale.Comment: 8 pages, LaTex; added references and clarifie

Alfalfa Cultivar Yield Test for South Dakota: 1998 Report

The South Dakota Alfalfa Cultivar Yield Test reports relative forage production characteristics for available cultivars at several locations in South Dakota. Alfalfas are entered in the test by seed companies and public breeders at their own discretion. A list of the cultivars and the companies marketing them is at the end of this bulletin

Higher order Josephson effects

Gaussian linking of superconducting loops containing Josephson junctions with enclosed magnetic fields give rise to interference shifts in the phase that modulates the current carried through the loop, proportional to the magnitude of the enclosed flux. We generalize these results to higher order linking of a superconducting loop with several magnetic solenoids, and show there may be interference shifts proportional to the product of two or more fluxes.Comment: 8 pages, 2 figure
