Obesity, Self-Complexity, And Compartmentalization: On The Implications Of Obesity For Self-Concept Organization, Bruce E. Blaine, C. E. Johnson Dec 2005

Obesity, Self-Complexity, And Compartmentalization: On The Implications Of Obesity For Self-Concept Organization, Bruce E. Blaine, C. E. Johnson

Statistics Faculty/Staff Publications

The relationship between obesity and structural aspects of the self-concept was examined in adult women. Participants were 119 adult women [age range: 18-73, M=26.9; body mass index (BMI) range: 16.2-54.7, M=27.3] who completed measures of self-esteem, self-complexity, and the spontaneous self-concept. BMI was associated with less complex and more compartmentalized self-knowledge and more frequent mention of weight-stereotypic traits as self-descriptive. The findings are discussed in the context of research on obesity- related stigma.


Five Years At The Magazine, Frank A. Farris Dec 2005

Five Years At The Magazine, Frank A. Farris

Mathematics and Computer Science

What do the editors of MAA journals do? What is so different about editing expository mathematics? After my five years as editor of Mathematics Magazine, I have strong opinions about these matters. The goal of most mathematics journals is to print the very latest results from the forefront of research. The goal of Mathematics Magazine is to remind us all why we loved mathematics in the first place, with stimulating articles and notes accessible to advanced undergraduates.

Radical Transcendentalism: Emerson, Muir and the Experience of Nature by James Brannon Palo Alto Center for Science and the Humanities, Palo Alto, CA ©2006 The uniquely American Transcendentalist School which formed in Harvard-influenced 1830's Cambridge brought a New Idea regarding man, spirit, and nature to a young country struggling to find its own voice. As its chief proponent, Ralph Waldo Emerson conveyed a philosophy that was considered radical in its time. The young John Muir, raised in an environment of harsh Puritan sensibilities and Christian dogma, took strongly to the Transcendental ideas as he was introduced to them at the …


Lead Optimization Of 7-Benzyloxy 2-(4′-Pyridylmethyl)Thio Isoflavone Aromatase Inhibitors, Bin Su, John C. Hackett, Edgar S. Diaz-Cruz, Young Woo Kim, Robert W. Brueggemeier Dec 2005

Lead Optimization Of 7-Benzyloxy 2-(4′-Pyridylmethyl)Thio Isoflavone Aromatase Inhibitors, Bin Su, John C. Hackett, Edgar S. Diaz-Cruz, Young Woo Kim, Robert W. Brueggemeier

Chemistry Faculty Publications

Aromatase, the enzyme responsible for estrogen biosynthesis, is a particularly attractive target in the treatment of hormone-dependent breast cancer. The synthesis and biological evaluation of a series of 2-(4′-pyridylmethyl)thio, 7-alkyl- or aryl-substituted isoflavones as potential aromatase inhibitors are described. The isoflavone derivatives demonstrate IC50 values from 79 to 553 nM and compete with the endogenous substrate, androstenedione. Data supporting the ability of these analogs to suppress aromatase enzyme activity in the SK-BR-3 breast cancer cell line are also presented.

Ferroelectric Polymer Langmuir–Blodgett Films For Nonvolatile Memory Applications, Stephen Ducharme, Timothy J. Reece, Christina M. Othon, R. K. Rannow Dec 2005

Ferroelectric Polymer Langmuir–Blodgett Films For Nonvolatile Memory Applications, Stephen Ducharme, Timothy J. Reece, Christina M. Othon, R. K. Rannow

Department of Physics and Astronomy: Faculty Publications

We review the potential for integrating ferroelectric polymer Langmuir–Blodgett (LB) films with semiconductor technology to produce nonvolatile ferroelectric random-access memory (NV-FRAM or NV-FeRAM) and data-storage devices. The prototype material is a copolymer consisting of 70% vinylidene fluoride (VDF) and 30% trifluoroethylene (TrFE), or P(VDF-TrFE 70:30). Recent work with LB films and more conventional solventformed films shows that the VDF copolymers are promising materials for nonvolatile memory applications. The prototype device is themetal–ferroelectric–insulator–semiconductor (MFIS) capacitance memory. Field-effect transistor (FET)-based devices are also discussed. The LB films afford devices with low-voltage operation, but there are two important technical hurdles that must be …

Issues Of Processing And Multiple Testing Of Seldi-Tof Ms Proteomic Data, Merrill D. Birkner, Alan E. Hubbard, Mark J. Van Der Laan, Christine F. Skibola, Christine M. Hegedus, Martyn T. Smith

U.C. Berkeley Division of Biostatistics Working Paper Series

A new data filtering method for SELDI-TOF MS proteomic spectra data is described. We examined technical repeats (2 per subject) of intensity versus m/z (mass/charge) of bone marrow cell lysate for two groups of childhood leukemia patients: acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL). As others have noted, the type of data processing as well as experimental variability can have a disproportionate impact on the list of "interesting" proteins (see Baggerly et al. (2004)). We propose a list of processing and multiple testing techniques to correct for 1) background drift; 2) filtering using smooth regression and cross-validated bandwidth …


The Relationship Between The Number Of Shots And The Quality Of Gamma Knife Radiosurgeries, D Cheek, Allen G. Holder, M Fuss, B Salter Dec 2005

The Relationship Between The Number Of Shots And The Quality Of Gamma Knife Radiosurgeries, D Cheek, Allen G. Holder, M Fuss, B Salter

Mathematics Faculty Research

Radiosurgery is a non-invasive alternative to brain surgery that uses a single focused application of high radiation to destroy intracerebral target tissues. A Gamma Knife delivers such treatments by using 201 cylindrically collimated cobalt-60 sources that are arranged in a hemispherical pattern and aimed to a common focal point. The accumulation of radiation at the focal point, called a \shot" due to the spherical nature of the dose distribution, is used to ablate (or destroy) target tissue in the brain. If the target is small and spherical, it is easily treated by choosing one of four available collimators (4, 8, …


Loss Aware Rate Allocations In H.263 Coded Video Transmissions, Xiao Su, Benjamin Wah Dec 2005

Loss Aware Rate Allocations In H.263 Coded Video Transmissions, Xiao Su, Benjamin Wah

Faculty Publications

For packet video, information loss and bandwidth limitation are two factors that affect video playback quality. Traditional rate allocation approaches have focused on optimizing video quality under bandwidth constraint alone. However, in the best-effort Internet, packets carrying video data are susceptible to losses, which need to be reconstructed at the receiver side. In this paper, we propose loss aware rate allocations in both group-of-block (GOB) level and macroblock level, given that certain packets are lost during transmissions and reconstructed using simple interpolation methods at the receiver side. Experimental results show that our proposed algorithms can produce videos of higher quality …


A Framework For Management Of Semistructured Probabilistic Data, Wenzhong Zhao, Alex Dekhtyar, Judy Goldsmith Dec 2005

A Framework For Management Of Semistructured Probabilistic Data, Wenzhong Zhao, Alex Dekhtyar, Judy Goldsmith

Computer Science and Software Engineering

This paper describes the theoretical framework and implementation of a database management system for storing and manipulating diverse probability distributions of discrete random variables with finite domains, and associated information. A formal Semistructured Probabilistic Object (SPO) data model and a Semistructured Probabilistic Query Algebra (SP-algebra) are proposed. The SP-algebra supports standard database queries as well as some specific to probabilities, such as conditionalization and marginalization. Thus, the Semistructured Probabilistic Database may be used as a backend to any application that involves the management of large quantities of probabilistic information, such as building stochastic models. The implementation uses XML encoding of …

The Bureau of Reclamation, Provo Area Office (Reclamation) proposes to replace the concrete spillway structure at Scofield Dam, the principal feature of the Scofield Project. This construction project would be completed under the Safety of Dams (SOD) Act of 1978 (Public Law 95-578, as amended). The proposed SOD modifications would correct safety deficiencies of the dam without affecting the purpose, or benefits of the dam. Reclamation also proposes to replace the existing gate house at its current position on the crest of the dam. This building is in poor condition and would be replaced with either a new concrete structure …


The Relationship Between Meteorological Patterns And Rural Ground Ozone Concentration, Dasen Kendrick Dec 2005

The Relationship Between Meteorological Patterns And Rural Ground Ozone Concentration, Dasen Kendrick

Masters Theses & Specialist Projects

Throughout the United States, many areas exceed the level of safe ground ozone (O3) concentration. Non-natural emissions made as result of daily human activities and natural emissions react photochemically to produce ground O3 concentration. Variation in ground O3 concentration is controlled by local and regional emissions, synoptic and mesoscale meteorology, and boundary layer chemistry and dynamics. When the right meteorological variables are present, rural areas can have unhealthy air conditions with high levels of ground O3 concentration similar to that of metropolitan areas. Particular ground O3 concentration episodes were analyzed to summarize what meteorological variables constitute a healthy or hazardous …

Existence And Uniqueness Of V-Asymptotic Expansions And Colombeau’S Generalized Numbers, Todor D. Todorov Dec 2005

Existence And Uniqueness Of V-Asymptotic Expansions And Colombeau’S Generalized Numbers, Todor D. Todorov

Mathematics

We define a type of generalized asymptotic series called v-asymptotic. We show that every function with moderate growth at infinity has a v-asymptotic expansion. We also describe the set of v-asymptotic series, where a given function with moderate growth has a unique v-asymptotic expansion. As an application to random matrix theory we calculate the coefficients and establish the uniqueness of the v-asymptotic expansion of an integral with a large parameter. As another application (with significance in the non-linear theory of generalized functions) we show that every Colombeau’s generalized number has a v-asymptotic expansion. A similar …

Fisheries Research Reports

Final FRDC Report - Project 2003/067

The capability to identify individual shark species from processed body parts is necessary for the WA Department of Fisheries to ensure the compliance of all WA fisheries with both existing protected species regulations and proposed new management measures for commercially important shark species. This project established a reference database of genetic profiles or ‘fingerprints’ for nine of Western Australia’s protected and commercially important shark species. Fingerprints from a 10th species, the shortfin mako (Isurus oxyrinchus) could not be obtained due to probable primer sequence mismatching. The database, in conjunction with an associated inspection and …


Klein Paradox With Spin-Resolved Electrons And Positrons, P Krekora, Q Su, Rainer Grobe Dec 2005

Klein Paradox With Spin-Resolved Electrons And Positrons, P Krekora, Q Su, Rainer Grobe

Faculty publications – Physics

Using numerical solutions to relativistic quantum field theory with space-time resolution, we illustrate how an incoming electron wave packet with a definite spin scatters off a supercritical potential step. We show that the production rate is reduced of only those electrons that have the same spin as the incoming electron is reduced. This spin-resolved result further clarifies the importance of the Pauli-exclusion principle for the Klein paradox.

A Scalable Correlation Aware Aggregation Strategy For Wireless Sensor Networks, Yujie Zhu, Ramanuja Vedantham, Seung Jong Park, Raghupathy Sivakumar Dec 2005

A Scalable Correlation Aware Aggregation Strategy For Wireless Sensor Networks, Yujie Zhu, Ramanuja Vedantham, Seung Jong Park, Raghupathy Sivakumar

Computer Science Faculty Research & Creative Works

Sensors-to-sink data in wireless sensor networks (WSNs) are typically correlated with each other. Exploiting such correlation when performing data aggregation can result in considerable improvements in the bandwidth and energy performance of WSNs. In order to exploit such correlation, we present a scalable and distributed correlation-aware aggregation structure that addresses the practical challenges in the context of aggregation in WSNs. Through simulations and analysis, we evaluate the performance of the proposed approach with centralized and distributed correlation aware and unaware structures.


Focused-Laser Interferometric Position Sensor, Stephen J. Friedman, Brett E. Barwick, Herman Batelaan Dec 2005

Focused-Laser Interferometric Position Sensor, Stephen J. Friedman, Brett E. Barwick, Herman Batelaan

Department of Physics and Astronomy: Faculty Publications

We describe a simple method to measure the position shifts of an object with a range of tens of micrometers using a focused-laser (FL) interferometric position sensor. In this article we examine the effects of mechanical vibration on FL and Michelson interferometers. We tested both interferometers using vibration amplitudes ranging from 0 to 20 μm. Our FL interferometer has a resolution much better than the diffraction grating periodicities of 10 and 14 μm used in our experiments. A FL interferometer provides improved mechanical stability at the expense of spatial resolution. Our experimental results show that Michelson interferometers cannot be used …


Numerical Modeling Of Hohlraum Radiation Conditions: Spatial And Spectral Variations Due To Sample Position, Beam Pointing, And Hohlraum Geometry, David H. Cohen, O. L. Landen, J. J. Macfarlane Dec 2005

Numerical Modeling Of Hohlraum Radiation Conditions: Spatial And Spectral Variations Due To Sample Position, Beam Pointing, And Hohlraum Geometry, David H. Cohen, O. L. Landen, J. J. Macfarlane

Physics & Astronomy Faculty Works

View-factor simulations are presented of the spatially varying radiation conditions inside double-ended gold Hohlraums and single-ended gold Hohlraums ('' halfraums '') used in inertial confinement fusion and high-energy density physics experiments [J. Lindl, Phys. Plasmas 11, 339 (2004); M. D. Rosen, Phys. Plasmas 3, 1803 (1996)]. It is shown that in many circumstances, the common assumption that the Hohlraum '' drive '' can be characterized by a single temperature is too simplistic. Specifically, the radiation conditions seen by an experimental package can differ significantly from the wall reemission measured through diagnostic holes or laser entrance holes (LEHs) by absolutely calibrated …

Spatial Autocorrelation Of Deer-Vehicle Accidents In Vigo County, J. Scott Horn Dec 2005

Spatial Autocorrelation Of Deer-Vehicle Accidents In Vigo County, J. Scott Horn

All-Inclusive List of Electronic Theses and Dissertations

Deer-vehicle accidents (DV As) are a problem in many areas. They cause millions of dollars in property damage, personal injury, and loss of life each year. This thesis examines whether DVAs in Vigo County, Indiana during the year 2000 were spatially autocorrelated; and whether DV As selected by deer habitat were spatially autocorrelated. Specifically using Moran's I to test for spatial autocorrelation this study determined if and to what degree spatial autocorrelation existed among these DVAs. A Moran's I value of .0023 shows that the accidents occurred randomly. These DV A data were then used to plot a map which …
