Section 271 of the Telecommunications Act allows theRegional Bell Operating Companies (RBOCs) to enter interLATAtelecommunications markets (previously prohibited by theModification of Final Judgment in 1982), provided they open localtelephone networks to competition.

This dissertation attempts to provide evidence of thecompetitive effects of RBOC interLATA entry on local telephonemarkets. To explor...

The Laser Engineered Net Shaping (LENS™) system,a type of directed laser manufacturing, has been used to createcompositionally graded materials. Using elemental blends, it ispossible to quickly vary composition, thus allowing fundamentalaspects of phase transformations and microstructural developmentfor particular alloy systems to be explored. In this work, it isshown that the use of elemental blends has been refined, suchthat bulk homogeneous specimens can be produced. When tested, th...

Plucked string instrument models have enjoyed anintensive history of development in computer music, offeringnovel methods for synthesis and ever-better simulations of actualacoustic instruments. Research in acoustics has improved ourunderstanding of the physics of musical instruments, and madeavailable to composers and performers more natural soundingcomputer-based instruments. This paper outlines issues in thedevelopment of plucked string software models, emphasizing theopportunities for expres...

When a sufficiently energetic short laser pulsepropagates through a medium it can generate an explosive increasein bandwidth leading to the creation of white light; this isknown as supercontinuum generation (SCG). Although it isfrequently referred to as a single process, SCG is actually theresult of many different parallel and competing processes. Inthis work we investigate the contribution of the individualphysical processes underlying the SCG effect, focusingspecifically on Raman processes and...

The interaction between trimethylamine dehydrogenase(TMADH) and electron-transferring flavoprotein (ETF), both frombacterium Methylophilus methylotrophus W3A1, has been examined.Our results indicate that the absorbance change previouslyattributed to changes in the environment of the FAD of ETF uponbinding to TMADH is instead due to electron transfer frompartially reduced as-isolated TMADH to ETF. Further, when thesemiquinone form of ETF is used instead of the oxidized form, themirror-image of th...

Propensity score matching is becoming an increasinglypopular tool in economics for dealing with selection issues.Recently economists have been evaluating matching methods bytrying to mimic the experimental evidence in social experimentswhere individuals were randomly assigned to job training. Thereis mixed evidence on whether matching can mimic the experimentresults.

Histone acetylation plays an important role in theassembly and modulation of chromatin structure. Two main types ofHistone AcetylTransferase (HAT), HAT-A and HAT- B, areresponsible for the acetylation of histones. The HAT-A enzymescatalyze the acetylation of nucleosomal core histones and arelocated in the nucleus. The HAT-B enzymes are primarilycytoplasmic and specific for the acetylation of free histones.The only HAT-B identified to date is comprised of two subunits,Hat1p and Hat2p. Hat1p is th...

While studying various features of the posteriordistribution of a vector-valued parameter using an MCMC sample,systematically subsampling of the MCMC output can only lead topoorer estimation. Nevertheless, a 1-in-k subsample is often allthat is retained in investigations where intensive computationsare involved or where speed is essential. The goal of benchmarkestimation is to produce a number of estimates based on the bestavailable information, i.e. the entire MCMC sample, and to usethese to im...

The description of initial consonant mutations in the Celticlanguages has frequently been attempted. Theoretical treatmentshave tended to focus on either the phonological aspects of thealternations or the syntactic aspects of distribution. Both ofthese perspectives, however, leave the topic incompletelycovered. On the one hand, there is no reliable synchronicphonetic conditioning generally to be found in the modernCeltic languages. On the other, the syntactic conditions arenot unified and freque...
