Analysis And Classification Of Nonlinear Dispersive Evolution Equations In The Potential Representation, U. A. Eichmann, A. Ludu, J. P. Draayer

Faculty Publications

A potential representation for the subset of travelling solutions of nonlinear dispersive evolution equations is introduced. The procedure involves reduction of a third-order partial differential equation to a first-order ordinary differential equation. The potential representation allows us to deduce certain properties of the solutions without the actual need to solve the underlying evolution equation. In particular, the paper deals with the so-called K(n, m) equations. Starting from their respective potential representations it is shown that these equations can be classified according to a simple point transformation. As a result, e.g., all equations with linear dispersion join the same equivalence class …

Simple, Compact Source For Low-Temperature Air Plasmas, D. P. Sheehan, J. Lawson, M. Sosa, Richard A. Long

Faculty Publications

A simple, compact source of low-temperature, spatially and temporally uniform air plasma using a Telsa induction coil driver is described. The low-power ionization discharge plasma is localized (2 cm X 0.5 cm X 0.1 cm) and essentially free of arc channels. A Teflon coated rolling cylindrical electrode and dielectric coated ground plate are essential to the source’s operation and allow flat test samples to be readily exposed to the plasma. The plasma is a copious source of ozone and nitrogen oxides. Its effects on various microbes are discussed.

Cross sections for e - p charged current deep inelastic scattering have been measured at a centre-of-mass energy of 318 GeV with an integrated luminosity of 16.4 pb -1 using the ZEUS detector at HERA. Differential cross sections dσ/dQ 2, dσ/dx and dσ/dy are presented for Q 2 > 200 GeV 2. In addition, d 2σ/(dxdQ 2) was measured in the kinematic range 280 GeV 2 < Q 2 < 30 000 GeV 2 and 0.015 < × < 0.42. The predictions of the Standard Model agree well with the measured cross sections. The mass of the W boson, determined from a fit to dσ/dQ 2, is M W = 80.3±2.1(stat.) ± 1.2(syst.) ± 1.0(PDF) GeV. © 2002 Published by Elsevier Science B.V.

Efficacy Of Angiotensin-Converting Enzyme Inhibition In Reducing Progression From Asymptomatic Left Ventricular Dysfunction To Symptomatic Heart Failure In Black And White Patients, Daniel L. Dries, Mark H. Strong, Richard S. Cooper, Mark H. Drazner

Faculty Publications

OBJECTIVES: This study was undertaken to determine whether enalapril had comparable efficacy in black and white patients with asymptomatic left ventricular dysfunction (ALVD) in preventing the development of symptomatic heart failure (HF). BACKGROUND: Recent studies have suggested that black patients with HF due to systolic dysfunction may derive less benefit than white patients with HF when treated with the same medication. METHODS: This is a post hoc analysis of the 4,054 black and white participants of the Studies of Left Ventricular Dysfunction Prevention Trial. RESULTS: Randomization to enalapril was associated with a comparable reduction in the relative risk of the …

Electronic Transport Through A Nuclear-Spin-Polarization-Induced Quantum Wire, Yuriy V. Pershin Dr, S. N. Shevchenko, I. D. Vagner, P. Wyder

Faculty Publications

Electron transport in a low-dimensional structure—the nuclear-spin-polarization-induced quantum wire is theoretically studied. In the proposed system the local nuclear-spin polarization creates the effective hyperfine field that confines the electrons with the spins opposite to the hyperfine field to the regions of maximal nuclear-spin polarization. The influence of the nuclear-spin relaxation and diffusion on the electron energy spectrum and on the conductance of the quantum wire is calculated and the experimental feasibility is discussed.

Density Profile And Flow Of Miscible Fluid With Dissimilar Constituent Masses, Ras B. Pandey, D. Stauffer, R. Seyfarth, Luis A. Cueva, J.F. Gettrust, Warren Wood

Faculty Publications

A computer simulation model is used to study the density profile and flow of a miscible gaseous fluid mixture consisting of differing constituent masses (m(A) = m(B)/3) through an open matrix. The density profile is found to decay with the height proportional to exp(-m(A(B))h), consistent with the barometric height law. The flux density shows a power-law increase proportional to (p(c) - p)(a) with mu similar or equal to 2.3 at the porosity 1 - p above the pore percolation threshold 1 - p(c).

Detection Of Superhumps In Xte J1118+480 Approaching Quiescence, C. Zurita, J. Casares, T. Shahbaz, R. M. Wagner, C. B. Foltz, P. Rodríguez-Gil, R. I. Hynes, P. A. Charles, E. Ryan, G. Schwarz, S. G. Starrfield

Faculty Publications

We present the results of our monitoring of the halo black hole soft X-ray transient (SXT) XTE J1118+480 during its decline to quiescence. The system has decayed 0.5 mag from 2000 December to its present near-quiescent level at R ≃ 18.65 (2001 June). The ellipsoidal light curve is distorted by an additional modulation that we interpret as a superhump of Psh = 0.17049(1) d i.e. 0.3 per cent longer than the orbital period. This implies a disc precession period Pprec ∼ 52 d. After correcting the average phase-folded light curve for veiling, the amplitude difference between the minima suggests that …

Book Review: Freedom Of Religion Under The European Convention On Human Rights, S. I. Strong

Faculty Publications

Oxford University Press has initiated a new series on the European Convention on Human Rights and, in light of recent world events, could not have found a more timely first installment than Carolyn Evans's book on freedom of religion. However, the choice of topics is sound even when one sets aside the current interest in the interplay between law and religion.

May Harvey Rest In Peace: Lakin V. Postal Life And Casualty Company, Robert H. Jerry Ii

More than a quarter-century has passed since I entered law school as a first-year student and began what has become a career of reading, among other things, cases. I cannot even guess the number of cases I have read in the ensuing years. Most of them have been fairly ordinary, but many have been wonderful for one reason or another. Because I hope to read at least as many cases during my next twenty-five years (or more) of legal study, I am not yet ready to crown any particular case with the title of "my favorite," "the most significant," or …

Charged current scattering of νμ, on 12C has been studied using a π+ decay-in-flight νμ beam at the Los Alamos Neutron Science Center. A sample of 66.9±9.1 events satisfying criteria for the exclusive reaction 12 C(νμ,μ-)12Ng.s. was obtained using a large liquid scintillator neutrino detector. The observed flux-averaged cross section (5.6±0.8±1.0) × 10-41 cm2 agrees well with reliable theoretical expectations. A measurement was also obtained for the inclusive cross section to all accessible 12N states 12C(νμ,μ-)X. This flux-averaged cross section is (10.6±0.3±1.8) × 10-40 cm2 which is lower than present theoretical calculations.

Relaxation Through Homogenization For Optimal Design Problems With Gradient Constraints, R. Lipton

Faculty Publications

The problem of the relaxation of optimal design problems for multiphase composite structures in the presence of constraints on the gradient of the state variable is addressed. A relaxed formulation for the problem is given in the presence of either a finite or infinite number of constraints. The relaxed formulation is used to identify minimizing sequences of configurations of phases.

Interdisciplinarity: The Road Ahead For Education In Digital Libraries, Anita Coleman

Faculty Publications

This article reviews the state of education in digital libraries and curriculum planning documents from professional associations in two areas: Library and Information Science; and Computing. It examines suggestions for integration and interdisciplinarity in education for digital libraries curricula using definitions of a discipline, interdisciplinarity, and the transdisciplinary structure of a university in order to discover how such integration may be successfully accomplished. A plan to use learning communities and develop an interdisciplinary curriculum for Knowledge Organization is briefly discussed.

Vibrational Modes Of Thin Oblate Clouds Of Charge, Thomas G. Jenkins, Ross L. Spencer

Faculty Publications

A numerical method is presented for finding the eigenfunctions (normal modes) and mode frequencies of azimuthally symmetric non-neutral plasmas confined in a Penning trap whose axial thickness is much smaller than their radial size. The plasma may be approximated as a charged disk in this limit; the normal modes and frequencies can be found if the surface charge density profile sigma(r) of the disk and the trap bounce frequency profile wz(r) are known. The dependence of the eigenfunctions and equilibrium plasma shapes on nonideal components of the confining Penning trap fields is discussed. The results of the calculation are compared …

An Enterprise-Based Grid Resource Management System, Mark J. Clement, Joseph Ekstrom, Quinn O. Snell, Kevin B. Tew

Faculty Publications

As the Internet began its exponential growth into a global information environment, software was often unreliable, slow and had difficulty in interoperating with other systems. Supercomputing node counts also continue to follow high growth trends. Supercomputer and grid resource management software must mature into a reliable computational platform in much the same way that web services matured for the Internet. DOGMA The Next Generation (DOGMA-NG) improves on current resource management approaches by using tested off-the-shelf enterprise technologies to build a robust, scalable, and extensible resource management platform. Distributed web service technologies constitute the core of DOGMA-NG’s design and provide fault …

[1] Results of a single-blind round-robin comparison of satellite primary productivity algorithms are presented. The goal of the round-robin exercise was to determine the accuracy of the algorithms in predicting depth-integrated primary production from information amenable to remote sensing. Twelve algorithms, developed by 10 teams, were evaluated by comparing their ability to estimate depth-integrated daily production (IP, mg C m(-2)) at 89 stations in geographically diverse provinces. Algorithms were furnished information about the surface chlorophyll concentration, temperature, photosynthetic available radiation, latitude, longitude, and day of the year. Algorithm results were then compared with IP estimates derived from (14)C uptake measurements …

Income Tax Planning For Long-Term Care, David M. English

Faculty Publications

Planning for long-term involves more than the preparation of powers of attorney and counseling on possible asset transfers to qualify for Medicaid reimbursement. Steps should also be taken to make certain that the person receiving care continues to file an income tax return and does so at a minimum possible income tax cost. Practitioners should be familiar with the procedure for filing a return on behalf of an incapacitated individual. The medical expense deduction, while of little importance for most taxpayers, is critical for many elderly, particularly for those receiving long-term care. Long-term care insurance and life insurance may be …

Swift Neighbors And Persistent Strangers: A Cross-Cultural Investigation Of Trust And Reciprocity In Social Exchange, Nancy R. Buchan, Rachel T.A. Croson, Robin M. Dawes

Faculty Publications

In four countries, levels of trust and reciprocity in direct-reciprocal exchange are compared with those in network-generalized exchanges among experimentally manipulated groups’ members (neighbors) or random experimental participants (strangers). Results show that cooperation decreases as social distance increases; and, that identical network-generalized exchanges generate different amounts of trusting behavior due solely to manipulated social identity between the actors.

This study demonstrates the interaction of culture and social identity on the propensity to trust and reciprocate and also reveals differing relationships between trust and reciprocation in each of the four countries, bringing into question the theoretical relationship between these cooperative behaviors.

After Ellerth: The Tangible Employment Action In Sexual Harassment Analysis, Susan Grover

Faculty Publications

In this Article, Professor Grover argues that courts too readily allow employers to avoid vicarious liability far supervisors' unlawful sexual harassment of subordinates. The Article explores the breadth of the affirmative defense first introduced in the Supreme Court's 1998 cases of Faragher v. Boca Raton and Burlington Indus., Inc. v. Ellerth. That defense clears an employer of liability for a supervisor's unlawful sexual harassment if (a) the employer exercised reasonable care to prevent and correct promptly any sexually harassing behavior, and (b) the plaintiff employee unreasonably failed to take advantage of any preventive or corrective opportunities provided by the employer …
