Parity Violation In The N + 3he → 3h + P Reaction: Resonance Approach, Vladimir Gudkov

Faculty Publications

The method based on microscopic theory of nuclear reactions has been applied for the analysis of parityviolatingeffects in few-body systems. Different parity-violating and parity-conserving asymmetries and theirdependence on neutron energy have been estimated for the n + 3He → 3H + p reaction. The estimated effectsare in a good agreement with available exact calculations.

Effective Ionic Conductivity Of A Novel Intermediate-Temperature Mixed Oxide-Ion And Carbonate-Ion Conductor, Xue Li, Guoliang Xiao, Kevin Huang

Faculty Publications

A systematic investigation on the effective ionic conductivity (σ_m) of a novel intermediate-temperature mixed oxide-ion and carbonate-ion conductor MOCC consisting of a ceria phase and a carbonate phase is reported. The study explicitly shows that the observed remarkable temperature-dependent σ_m is primarily the result of softening/melting of the carbonate phase as the physical state of the carbonate phase transforms from solid, softened to molten. Differential scanning calorimetry analysis complements the understanding of the observed electrical behavior by revealing temperatures of melting and solidification in agreement with the onset temperatures of σ_m. In addition, the …

A Sequel To “A Space Topologized By Functions From Omega To Omega”, Tetsuya Ishiu, Akira Iwasa

Faculty Publications

We consider a topological space ⟨𝑋, 𝜏 (ℱ)⟩, where 𝑋 = {𝑝 ∗} ∪ [𝜔 Å~ 𝜔] and ℱ ⊆ 𝜔𝜔. Each point in 𝜔 Å~ 𝜔 is isolated and a neighborhood of 𝑝∗ has the form {𝑝∗}∪{⟨𝑖, 𝑗⟩ : 𝑖 ≥ 𝑛, 𝑗 ≥ 𝑓(𝑖)} for some 𝑛 ∈ 𝜔 and 𝑓 ∈ ℱ. We show that there are subsets ℱ and 𝒢 of 𝜔𝜔 such that ℱ is not bounded, 𝒢 is bounded, yet ⟨𝑋, 𝜏 (ℱ)⟩ and ⟨𝑋, 𝜏 (𝒢)⟩ are homeomorphic. This answers a question of the second author posed in A space topologized by functions …

Optimization Design Of Electrodes For Anode-Supported Solid Oxide Fuel Cells Via Genetic Algorithm, Junxiang Shi, Xingjian Xue

Faculty Publications

Porous electrode is the critical component of solid-oxide fuel cells (SOFCs) and provides a functional material backbone for multi-physicochemical processes. Model based electrode designs could significantly improve SOFC performance. This task is usually performed via parameter studies for simple case and assumed property distributions for graded electrodes. When nonlinearly coupled multiparameters of electrodes are considered, it could be very difficult for the model based parameter study method to effectively and systematically search the design space. In this research, the optimization approach with a genetic algorithm is demonstrated for this purpose. An anode-supported proton conducting SOFC integrated with a fuel supply …

Geometry-Dependent Oxygen Diffusion Flux And Limiting Current Density Of The Cathode In A Cathode-Supported Solid Oxide Fuel Cell, Kevin Huang, James L. Shull

Faculty Publications

An analysis is performed on the diffusion of oxygen through tubular porous cathode substrates having several different geometries. It is shown that the flux of oxygen as it diffuses through these different substrate geometries can be explicitly expressed by a general analytical form with a unique geometric factor for each type of substrate geometry. Experimental measurements of the geometry-independent term, oxygen diffusivity, were conducted for two representative geometries: cylindrical and triangular tubes. These measurements show good agreement between samples with similar porosities and thus favorably support the oxygen flux equations presented. Formulations for the limiting current density were also derived …

A Contractual Approach To Shareholder Oppression Law, Benjamin Means

Faculty Publications

According to standard law and economics, minority shareholders in closely held corporations must bargain against opportunism by controlling shareholders before investing. Put simply, you made your bed, now you must lie in it. Yet most courts offer a remedy for shareholder oppression, often premised on the notion that controlling shareholders owe fiduciary duties to the minority or must honor the minority's reasonable expectations. Thus, law and economics, the dominant mode of corporate law scholarship, appears irreconcilably opposed to minority shareholder protection, a defining feature of the existing law of close corporations.

This Article contends that a more nuanced theory of …

Cultural Norms And Race Discrimination Standards: A Case Study In How The Two Diverge, Derek W. Black

Faculty Publications

The legal standard for race discrimination - the intent standard - has been scrutinized and justified for decades, but that conversation has occurred almost entirely within the legal community. Relatively little effort has been made to engage the public. This Article posits that the discussion of discrimination standards must account for and include public understandings of race and discrimination because race is a socially constructed concept and discrimination is culturally contingent. Race discrimination standards based solely upon the legal community’s perceptions are susceptible to significant flaws. This Article begins the incorporation of public understandings of race and discrimination by examining …

Does Ricci Herald A New Disparate Impact?, Joseph Seiner, Benjamin N. Gutman

Faculty Publications

Federal law has long prohibited not just intentional discrimination by employers, but also practices that have an unintentional disparate impact on minorities. A cryptic passage at the end of the Supreme Court's recent decision in Ricci v. DeStefano may signal a sea change for this disparate impact doctrine. Ricci, a lawsuit about a civil-service exam for firefighters, received widespread attention as a case about intentional discrimination. We show that the opinion also can be read to suggest a new affirmative defense for employers facing claims of disparate impact. Before Ricci, disparate impact was a purely no-fault doctrine. An employer was …

Judges Playing Jury: Constitutional Conflicts In Deciding Fair Use On Summary Judgment, Ned Snow

Faculty Publications

Issues of fair use in copyright cases are usually decided at summary judgment. But it was not always so. For well over a century, juries routinely decided these issues. The law recognized that fair use issues were highly subjective and thereby inherently factual — unfit for summary disposition by a judge. Today, however, all this has been forgotten. Judges are characterizing factual issues as purely legal so that fair use may be decided at summary judgment. Even while judges acknowledge that reasonable minds may disagree on these issues, they characterize the issues as legal, preventing them from ever reaching a …

Systematic Approach To Electrostatically Induced 2d Crystallization Of Nanoparticles At Liquid Interfaces, Sumit Kewalramani, Suntao Wang, Yuan Lin, Huong Giang Nguyen, Qian Wang, Masafumi Fukuto, Lin Yang

Faculty Publications

We report an experimental demonstration of a strategy for inducing two-dimensional (2D)crystallization of charged nanoparticles on oppositely charged fluid interfaces. This strategy aims to maximize the interfacial adsorption of nanoparticles, and hence their lateral packing density, by utilizing a combination of weakly charged particles and a high surface charge density on the planar interface. In order to test this approach, we investigated the assembly of cowpea mosaic virus (CPMV) on positively charged lipid monolayers at the aqueous solution surface, by means of in situX-ray scattering measurements at the liquid–vapor interface. Theassembly was studied as a function of the solution …

Shelf Edge Tide Correlated Eddies Along The Southeastern United States, Dana K. Savidge, Jonathan Norman, Colton Smith, Julie A. Amft, Trent Moore, Catherine Edwards, George Voulgaris

Faculty Publications

High frequency radar observations in the Southeastern United States have revealed sequences of small short‐lived cyclonic eddies along the shoreward edge of the Gulf Stream, that spin up as the local tide turns alongshelf antiparallel to the Stream. Eddies propagate equatorward along the shelf edge, sometimes progressing shoreward before dissipating one to three hours later. They are distinctly different from Gulf Stream meander eddies, which propagate poleward. In this article, radar and mooring data are used to establish three important aspects of these neweddies: they represent an instability process operating at a previously unidentified frequency, scale, and cross‐Stream position; they …

The Relative Influence Of Demographic, Individual, Social, And Environmental Factors On Physical Activity Among Boys And Girls, Carrie D. Patnode, Leslie A. Lytle, Darin J. Erickson, John R. Sirard, Daheia J. Barr-Anderson, Mary Story

Faculty Publications

Background: This study aimed to evaluate the associations of selected demographic, individual, social, and environmental factors with moderate-to-vigorous physical activity (MVPA) in a sample of children and adolescents.

Methods: MVPA was assessed among youth (n = 294) 10-17-years-old using the ActiGraph accelerometer. Youth completed measures of demographic and individual variables related to physical activity (PA), perceived social support by parents and peers, and perceived neighborhood characteristics. Parents completed the long-form of the International Physical Activity Questionnaire. The Physical Activity and Media Inventory was used to measure the home environment and Geographical Information Systems software was used to measure the physical …

Perfect Little Feminists? Young Girls In The Us Interpret Gender, Violence, And Friendship In Cartoons, Spring-Serenity Duvall

Faculty Publications

Girls’ studies has emerged as a dynamic area of scholarship that examines the cultural construction of girlhood, the role that girls play in society, their identity formation, and their representation in media. This paper extends previous research by interviewing young girls about their interactions with each other as they view and interpret animated cartoons. Expanding claims that Girl Power programs such as The Powerpuff Girls empower viewers, I also discuss the role of third wave, commodity, and post feminism in influencing girls’ expectations of gender equality even as they embrace gender role differences. In discussing the importance of researchers engaging …

Age-Related Changes In Types And Contexts Of Physical Activity In Middle School Girls, Russell R. Pate, James F. Sallis, Dianne S. Ward, June Stevens, Gregory J. Welk, Deborah Rohm Young, Jared B. Jobe, Patricia K. Strikmiller

Faculty Publications

Background - Because girls are less physically active than boys, it is important to understand the types of activities preferred by girls, and changes in those preferences over time, in order to design effective physical activity interventions.

Purpose - To describe developmental trends in participation in specific forms of physical activity in 6th- and 8th-grade girls.

Methods - Data for this study are from the Trial of Activity for Adolescent Girls. Self-reported physical activity, anthropometric, and demographic data were collected from random cross sections of 6th-grade girls in 36 middle schools in six U.S. communities. The same data were collected …

Structures Of Human Thymidylate Synthase R163k With Dump, Fdump And Glutathione Show Asymmetric Ligand Binding, Lydia M. Gibson, Lesa R. Celeste, Leslie L. Lovelace, Lukasz Lebioda

Faculty Publications

Thymidylate synthase (TS) is a well validated target in cancer chemotherapy. Here, a new crystal form of the R163K variant of human TS (hTS) with five subunits per asymmetric part of the unit cell, all with loop 181-197 in the active conformation, is reported. This form allows binding studies by soaking crystals in artificial mother liquors containing ligands that bind in the active site. Using this approach, crystal structures of hTS complexes with FdUMP and dUMP were obtained, indicating that this form should facilitate high-throughput analysis of hTS complexes with drug candidates. Crystal soaking experiments using oxidized glutathione revealed that …

More Collaboration - More Power In Combating Ill Health, Ilkka Vuori, Steven N. Blair, Fiona C. Bull, Peter T. Katzmarzyk

Faculty Publications

This symposium highlighted the position of physical activity as one of the most important factors causally related to common non-communicable diseases (NCDs), and discussed the need for including physical activity in comprehensive prevention strategies and policies to combat the major NCDs. Lifestyle factors such as smoking, physical inactivity, and obesity are all major risk factors for ischemic heart disease, cerebrovascular disease, and several cancers, and physical inactivity globally ranks as the fourth leading risk factor for mortality. Despite the solid evidence that physical activity is related to several NCDs, stronger advocacy actions are required because physical activity is not viewed …

Modeling-Free Bounds On Nonrenormalizable Isotropic Lorentz And Cpt Violation In Qed, Brett David Altschul

Faculty Publications

The strongest bounds on some forms of Lorentz and CPT violation come from astrophysical data, and placing such bounds may require understanding and modeling distant sources of radiation. However, it is also desirable to have bounds that do not rely on these kinds of detailed models. Bounds that do not rely on any modeling of astrophysical objects may be derived both from laboratory experiments and certain kinds of astrophysical observations. The strongest such bounds on isotropic modifications of electron, positron, and photon dispersion relations of the form E^2 = p^2 + m^ 2 + epsilon p^3 come from data on …

Evaluation Of The Late Life Disability Instrument In The Lifestyle Interventions And Independence For Elders Pilot (Life-P) Study, Fang-Chi Hsu, W. Jack Rejeski, Edward H. Ip, Jeff A. Katula, Roger A. Fielding, Alan M. Jette, Stephanie A. Studenski, Steven N. Blair, Michael E. Miller

Faculty Publications

Background: The late life disability instrument (LLDI) was developed to assess limitations in instrumental and management roles using a small and restricted sample. In this paper we examine the measurement properties of the LLDI using data from the Lifestyle Intervention and Independence for Elders Pilot (Life-P) study.

Methods: LIFE-P participants, aged 70-89 years, were at elevated risk of disability. The 424 participants were enrolled at the Cooper Institute, Stanford University, University of Pittsburgh, and Wake Forest University. Physical activity and successful aging health education interventions were compared after 12-months of follow-up. Using factor analysis, we determined whether the LLDI's factor …

Empowerment, Innovation, And Service: Law School Programs Provide Access To Justice And Instill A Commitment To Serve, Lisa V. Martin, Dale Margolin, Steve Berenson, Karen Pearlman, Maryann Zavez

Faculty Publications

Law schools around the country seek to fill the legal needs of their communities in ways that are both innovative and mutually beneficial to clients and students. This article describes five pro bono and clinical programs, at the University of Richmond School of Law, The Earle Mack School of Law at Drexel University, Catholic University Columbus School of Law, the Thomas Jefferson School of Law, and Vermont Law School, where law students, under the supervision of law professors or community professionals, provide assistance or legal representation to underserved and often marginalized populations needing help with family law problems, including parents …

Critical Theory, Libraries And Culture, Jenny Bossaller, Denice Adkins, Kim M. Thompson

Faculty Publications

There are disparate notions among people within the broad field of information and library science regarding exactly what comprises information science. One broad definition is provided by Tefko Saracevic: “Information science is a field of professional practice and scientific inquiry addressing the problem of effective communication of knowledge records – ʻliteratureʼ – among humans in the context of social, organizational, and individual need for and use of information” (1055- 1056). At its most basic, it seems that information science could be a neutral science if, indeed, it studies everything that is communicated, in any form. However, as noted in the …

In Memoriam: Gil Friedman, Harvey Starr

Faculty Publications

Gil Friedman, lecturer in political science at Tel Aviv University, passed away on July 16, 2009, at the age of 42 after a short bout with cancer. Much too young, and with so much promise, Gil's death was an unexpected shock to his relatives, friends, and colleagues. His loss is all the more tragic because those who knew Gil were struck by his seemingly boundless energy, his enormous intellectual curiosity, his constant stream of ideas, and his incredible work ethic—all fed by a seemingly insatiable desire to read everything (ever) written in the areas of his current interest.

Epstein's Razor, David G. Owen

Faculty Publications

Richard Epstein, over a long and distinguished career, has offered inspired insights into how a legal system should be framed to serve the goals of those it governs. In that pursuit, he has relentlessly applied a sharp logic - call it Epstein's Razor - to shave away the detritus of complexity and confusion that surround perplexing problems, leaving standing only truths unscathed by competition among ideas. Over decades of diverse writings on law and political theory, highlighted by his elegant Simple Rules for a Complex World, Professor Epstein offers a vision of law constructed on the view that simplicity in …

Construing Wills And Trusts During The Estate Tax Hiatus In 2010, S. Alan Medlin, F. Ladson Boyle

Faculty Publications

Many estate planners have drafted wills and revocable trusts with dispositive provisions based on formulas. These formulas often use language based on transfer tax terminology. For clients who die in 2010, the language used in these formulas will be ambiguous, if not apparently meaningless, because Congress failed to re-institute the estate tax for 2010. The resulting 2010 estate tax hiatus will result in will and revocable trust construction problems for the estates of many decedents who die during the hiatus. Courts will have to use statutory and common law construction methods to attempt to determine the decedent's dispositive intentions. This …

Radical Spin Helix In Two-Dimensional Electron Systems With Rashba Spin-Orbit Coupling, Yuriy V. Pershin Dr, Valeriy A. Slipko

Faculty Publications

We suggest a long-lived spin-polarization structure, a radial spin helix, and study its relaxation dynamics. For this purpose, starting with a system of equations for spin-polarization density, we find its general solution in the axially symmetric case. It is demonstrated that the radial spin helix of a certain period relaxes slower than homogeneous spin polarization and plain spin helix. Importantly, the spin polarization at the center of the radial spin helix stays almost unchanged at short times. At longer times, when the initial nonexponential relaxation region ends, the relaxation of the radial spin helix occurs with the same time constant …
