Moments And Commutators Of Probability Measures, Luigi Accardi, Hui Hsiung Kuo, Aurel Stan

Faculty Publications

Let a0, a- and a+ be the preservation, annihilation, and creation operators of a probability measure μ on ℝd, respectively. The operators a0 and [a -, a+] are proven to uniquely determine the moments of μ. We discuss the question: "What conditions must two families of operators satisfy, in order to ensure the existence of a probability measure, having finite moments of any order, so that, its associated preservation operators and commutators between the annihilation and creation operators are the given families of operators?" For the case d = 1, a satisfactory answer to this question is obtained as a …

A Computer Model Of Gluconeogenesis And Lipid Metabolism In The Perfused Liver, Elie Chalhoub, Richard W. Hanson, Joanne M. Belovich

Chemical & Biomedical Engineering Faculty Publications

A mathematical model of the perfused rat liver was developed to predict intermediate metabolite concentrations and fluxes in response to changes in various substrate concentrations in the perfusion medium. The model simulates gluconeogenesis in the liver perfused separately with lactate and pyruvate and the combination of these substrates with fatty acids (oleate). The model consists of key reactions representing gluconeogenesis, glycolysis, fatty acid metabolism, tricarboxylic acid cycle, oxidative phosphorylation, and ketogenesis. Michaelis-Menten-type kinetic expressions, with control by ATP/ADP, are used for many of the reactions. For key regulated reactions (fructose-1,6-bisphosphatase, phosphofructokinase, pyruvate carboxylase, pyruvate dehydrogenase complex, and pyruvate kinase), rate …

Searching For Patterns In The Laws Governing Access To Records And Meetings In The Fifty States By Using Multiple Research Tools, Bill F. Chamberlin, Cristina Popsecu, Michael F. Weigold, Nissa Laughner

UF Law Faculty Publications

In this Essay, the authors explain how the combination of social science and legal methodologies can effectively answer complex questions involving public access laws. Discussing the project's methodology could also be useful to legal and communication scholars wishing to develop and improve state law compilations in order to identify in greater detail public policy established by state legislatures and the courts. Furthermore, although the MBCAP so far has focused on aspects of state public records laws, the methodology presented here may be replicated or modified for other areas of law where ranking and comparison of multiple jurisdictions would be useful. …

The Substitution Theorem For Semilinear Stochastic Partial Differential Equations, Salah-Eldin A. Mohammed, Tusheng Zhang

Articles and Preprints

In this article we establish a substitution theorem for semilinear stochastic evolution equations (see's) depending on the initial condition as an infinite-dimensional parameter. Due to the infinitedimensionality of the initial conditions and of the stochastic dynamics, existing finite-dimensional results do not apply. The substitution theorem is proved using Malliavin calculus techniques together with new estimates on the underlying stochastic semiflow. Applications of the theorem include dynamic characterizations of solutions of stochastic partial differential equations (spde's) with anticipating initial conditions and non-ergodic stationary solutions. In particular, our result gives a new existence theorem for solutions of semilinear Stratonovich spde's with anticipating …

The Webt Campaign On The Blazar 3c 279 In 2006, Markus Böttcher, Jeff W. Robertson, Stéphane Vennes

Aerospace, Physics, and Space Science Faculty Publications

The quasar 3C 279 was the target of an extensive multiwavelength monitoring campaign from 2006 January through April. An optical-IR-radio monitoring campaign by the Whole Earth Blazar Telescope (WEBT) collaboration was organized around target-of-opportunity X-ray and soft γ-ray observations with Chandra and INTEGRAL in 2006 mid-January, with additional X-ray coverage by RXTE and Swift XRT. In this paper we focus on the results of the WEBT campaign. The source exhibited substantial variability of optical flux and spectral shape, with a characteristic timescale of a few days. The variability patterns throughout the optical BVRI bands were very closely correlated with each …

A Hardware Threat Modeling Concept For Trustable Integrated Circuits, Jia Di, Scott C. Smith

Electrical and Computer Engineering Faculty Research & Creative Works

Similar to the effects of software viruses, hardware can also be compromised by introduction of malicious logic into circuits to cause unwanted system behaviors. This can be done by changing or adding internal logic, in such a way that it is undetectable using traditional testing and verification tools and techniques. Therefore, the user of the circuit needs to decide whether it can be trusted, i.e., it only performs functions defined in the original circuit specification (no more and no less), before employing it in the system. in this paper, a preliminary methodology is proposed to model potential hardware threats in …

Nebraska Water Center: Faculty Publications

Recent studies of surface waters in North America, Japan, and Europe have reported the presence of steroidogenic agents as contaminants. The current study has three objectives: 1) to determine if steroidogenic compounds are present in the Elkhorn River, 2) to determine if sediments collected from the Elkhorn River can act as a source of steroidogenic compounds to aquatic organisms, and 3) to determine if site-specific biological effects are apparent in the hepatic gene expression of fathead minnows. Evidence was obtained using three approaches: 1) deployment of polar organic chemical integrative samplers (POCIS), 2) deployment of caged fathead minnows, and 3) …

Data Note: Disability And Occupation, Frank A. Smith, David Clark

Data Note Series, Institute for Community Inclusion

It is well-documented that people with disabilities have a significantly lower rate of employment than people without disabilities (36% versus 74% according to the 2006 American Community Survey (ACS). Less is known about the types of work they do. Using the occupational classification system within the ACS, researchers explored the prevalence of people with disabilities within occupational groupings and discuss its relationship to occupational growth. Future analysis will address variation across disability groups.

Understanding The Influences On The Homework Experiences Of Low-Socioeconomic, African American, Kindergarten Students, Sheryl Florantine Venable

College of Graduate Studies: Theses & Dissertations

Mixed views exist on the benefits of homework for elementary students. The focus of this interpretive case study was to understand the influences on the homework experiences of 10 low-socioeconomic, African American kindergarten students. The general research question framed by Bandura's (1986) social cognitive theory was stated as followed: How do the students' personal processes, the parents' home and the teachers school classroom environments, and the students' school academic behaviors interact to influence the homework experiences of low-socioeconomic, African-American kindergarten students? The data were analyzed using the constant comparative method. Interviews and records of homework and quiz grades revealed that …

Analysis Of Compelling And Constraining Forces Experienced By Georgia High School Principals Implementing Smaller Learning Communities, Martin Gregory Waters

College of Graduate Studies: Theses & Dissertations

The research on smaller learning communities is extensive, and the benefits are documented, compelling, and persuasive. While the practice can become the engine for higher achievement, stakeholders must adjust to a new paradigm of school operations. In many cases, prior procedures and traditions must be abandoned to achieve academic, social, and school environmental goals. Several unknown factors exist in Georgia's high schools as administrators attempt to find programs and procedures to meet the needs of rapidly growing and diverse student populations. First, little is known about the experiences of Georgia high school principals implementing smaller learning communities, nor the forces …

An Experiment In Joint Product Price Optimization: Price Elasticities And Substitution Decisions Of The Hungry Barfly, Jeffrey Coursen

All Theses

The subject of optimal pricing is consistently on the forefront of debate among firms in all market situations. Optimal pricing is further complicated when there are common resource inputs associated with the production of a multitude of different products. Economic theory has suggestions for pricing optimally in a variety of market conditions, from perfect competition, to perfect monopoly. This paper presents an experiment where a firm is attempting to optimally price multiple products with common cost inputs subject to monopolistic market conditions. The result supports the hypothesis of substitution amongst the product line relative to prices, as well as presents …

Use Of Native Seed Mixtures To Improve Erosion Control And Wildlife Habitat On Log Landings Following Timber Harvest In The Upper Elk Watershed Of West Virginia, Lisa R. Tager

Graduate Theses, Dissertations, and Problem Reports (ETD)

Foresters in West Virginia follow BMP guidelines by reseeding retired log landings with inexpensive grasses that quickly provide erosion control. However, these grasses typically are not native nor do they provide high quality forage for wildlife. I developed 3 native seed mixtures for log landing reclamation that would maintain sediment control, as well as enhance wildlife habitat. These mixtures included an erosion control mixture, a wildlife mixture, and a wildflower mixture. I assessed sediment control, biomass production, vegetation structure, forage quality, and small mammal usage of my native mixtures and a commonly used, nonnative traditional mixture in 2005 and 2006. …

Three-Dimensional, High Resolution, Computerized Ionospheric Tomographic Imaging And Computational Modeling Of An Artificial Ionospheric Cavity, Craig A. Selcher

Graduate Theses, Dissertations, and Problem Reports (ETD)

Tomographic techniques use line integral measurements to reconstruct local values of the measured parameter. These techniques have been applied to the ionosphere by using radio transmissions to measure the integral of electron density between a satellite and a chain of ground-based receiving stations. The resultant reconstructions form a two-dimensional map of the electron density in the plane of the satellite/receiver chain. Insufficient quantity of receivers and not having a complete range of accessible look angles with the available receivers are responsible for the non-uniqueness in the reconstructions. The limited look angle problem can be alleviated by making use of alternative …

Ralbp1 In Stress Resistance, Kenneth Drake

Chemistry & Biochemistry Dissertations - Archive

Ralbp1 is a multi-specific transporter of glutathione conjugates as well as unconjugated amphiphilic toxins. Because glutathione conjugates are major metabolites of toxic lipid peroxidation products generated as a consequence of oxidant and radiant stress, the hypothesis is put forth that the function of Ralbp1 in-vivo and in vitro should be to protect organisms from chemical stress by removing toxic chemicals. Studies described in this dissertation were designed to prove this hypothesis. We tested the hypothesis by examining whether the inhibition or augmentation of Ralbp1 would sensitize or protect cells and whole animals from the toxic effects of chemicals and radiation. …

In an era of high accountability with many initiatives being proposed for school reform, effective school research continues to provide valuable research-based information to the school principal, superintendent and larger educational community. By examining the school in relation to this research-based information, educational leaders are informed about factors that promote student achievement. This study surveyed teachers and administrators on eight middle school …

A Comparison Of The Kodaly Methodology And Feierabend's Conversational Solfege, Aimee Noelle Peek

Theses and Dissertations

This paper compares and contrasts Zoltan Kodaly' s music methodology with John Feierabend's Conversational Solfege. Both systems for teaching music are founded upon similar philosophies and goals and emphasize singing in the classroom. Solfege, rhythmic syllables, and movement are incorporated in both methodologies. The order in which these solfege syllables and rhythmic meters are introduced to students differs between the two methods. The reasons behind this difference are discussed in detail. Folk music, the primary musical material utilized by both methodologies, is also examined.

All concepts in either the Kodaly method or Conversational Solfege progress through specific stages to ensure …

Route Validation Using Radio Frequency Identification, William T. Watson

Theses and Dissertations

In recent years, radio frequency identification (RFID) has been proposed and implemented in a variety of applications where tracking objects, animals or people is desirable. This paper proposes a novel approach to the application of RFID technology in those applications where it is possible to validate a person or an object's passive contact with a given or arbitrary set of fixed points along a predefined route. The notable departure from the typical application of RFID technology is that in this scheme, the transponders are permanently installed while the interrogator is affixed to a person or object that travels the course. …
