The analysis is intended to help state leaders, educators, and others obtain a picture of highly qualified teachers in their state, and to be able to compare their state statistics with states across the nation. ...

Scattering Of Low- To Intermediate-Energy Positrons From Molecular Hydrogen, David D. Reid, William B. Klann, J. M. Wadehra

Physics and Astronomy Faculty Research Publications

Using a complex model potential, we have calculated the total, integrated elastic, momentum transfer, absorption, and differential cross sections for positrons scattered from molecular hydrogen. The widely available software package GAUSSIAN is used to generate the radial electronic charge density of the molecule which is used to produce the interaction potentials. The quasifree absorption potential, previously developed and used for positron-atom scattering, is extended to positron scattering from molecular targets. It is shown that this model potential approach produces accurate results even into the low-energy regime.

Fire Ant War Rages At Field Station, Jennifer Southall

University of Mississippi News

OXFORD, Miss. - University of Mississippi entomologist James Anderson likes to quote famed biologist E.O. Wilson on the topic of fire ants. Wilson once said that fire ants are the "Vietnam of entomology." He was referring specifically to the U.S. Department of Agriculture's 20-year, $200 million failed campaign to eradicate the South American invaders through the use of insecticides.

Faculty Publications

The primary scientific mission of the Black Hole Finder Probe (BHFP), part of the NASA Beyond Einstein program, is to survey the local Universe for black holes over a wide range of mass and accretion rate. One approach to such a survey is a hard X-ray coded-aperture imaging mission operating in the 10-600 keV energy band, a spectral range that is considered to be especially useful in the detection of black hole sources. The development of new inorganic scintillator materials provides improved performance (for example, with regards to energy resolution and timing) that is well suited to the BHFP science …

The MEGA mission would enable a sensitive all-sky survey of the medium-energy γ-ray sky (0.3-50 MeV). This mission will bridge the huge sensitivity gap between the COMPTEL and OSSE experiments on the Compton Gamma Ray Observatory, the SPI and IBIS instruments on INTEGRAL and the visionary ACT mission. It will, among other things, serve to compile a much larger catalog of sources in this energy range, perform far deeper searches for supernovae, better measure the galactic continuum emission as well as identify the components of the cosmic diffuse emission. The large field of view will allow MEGA to continuously monitor …

Tsc2 Modulates Actin Cytoskeleton And Focal Adhesion Through Tsc1-Binding Domain And The Rac1 Gtpase, Elena Goncharova, Dmitry Goncharov, Daniel J. Noonan, Vera P Krymskaya

Molecular and Cellular Biochemistry Faculty Publications

Tuberous sclerosis complex (TSC) 1 and TSC2 are thought to be involved in protein translational regulation and cell growth, and loss of their function is a cause of TSC and lymphangioleiomyomatosis (LAM). However, TSC1 also activates Rho and regulates cell adhesion. We found that TSC2 modulates actin dynamics and cell adhesion and the TSC1-binding domain (TSC2-HBD) is essential for this function of TSC2. Expression of TSC2 or TSC2-HBD in TSC2-/- cells promoted Rac1 activation, inhibition of Rho, stress fiber disassembly, and focal adhesion remodeling. The down-regulation of TSC1 with TSC1 siRNA in TSC2-/- cells activated Rac1 and induced loss of …

Minimum Power Configuration In Wireless Sensor Networks, Guoliang Xing, Chenyang Lu, Ying Zhang, Qingfeng Huang, Robert Pless

All Computer Science and Engineering Research

This paper proposes the minimum power configuration (MPC) approach to energy conservation in wireless sensor networks. In sharp contrast to earlier research that treats topology control, power-aware routing, and sleep management in isolation, MPC integrates them as a joint optimization prob-lem in which the power configurationof a network consists of a set of active nodes and the transmission powers of the nodes. We show through analysis that the minimum power configu-ration of a network is inherently dependent on the data rates of sources. We propose several approximation algorithms with provable performance bounds compared to the optimal solu-tion, and a practical …

Signature Of Electron Capture In Iron‐Rich Ejecta Of Sn 2003du, Peter Hoflich, Christopher L. Gerardy, Ken-Ichi Nomoto, Kentaro Motohara, Robert A. Fesen

Dartmouth Scholarship

Late-time near-infrared and optical spectra of the normal-bright Type Ia supernova 2003du about 300 days after the explosion are presented. At this late epoch, the emission profiles of well-isolated [Fe II] lines (in particular that of the strong 1.644 μm feature) trace out the global kinematic distribution of radioactive material in the expanding supernova ejecta. In SN 2003du, the 1.644 μm [Fe II] line seems to show a flat-topped profile, indicative of a thick but hollow-centered expanding shell, rather than a strongly peaked profile that would be expected from a "center-filled" distribution. Based on detailed models for exploding Chandrasekhar-mass white …

Magnetoelectronics With Magnetoelectrics, Christian Binek, Bernard Doudin

Christian Binek Publications

Magnetoelectric films are proposed as key components for spintronic applications. The net magnetic moment created by an electric field in a magnetoelectric thin film influences the magnetization state of a neighbouring ferromagnetic layer through exchange coupling. Pure electrical control of magnetic confi gurations of giant magnetoresistance spin valves and tunnelling magnetoresistance elements is therefore achievable. Estimates based on documented magnetoelectric tensor values show that exchange fields reaching 100 mT can be obtained. We propose a mechanism alternative to current-induced magnetization switching, providing access to a wide range of device impedance values and opening the possibility of simple logic functions.

Inelastic Electron Tunneling Via Molecular Vibrations In Single-Molecule Transistors, L H. Yu, Z K. Keane, Jacob W. Ciszek, L Cheng, M P. Stewart, J M. Tour, D Natelson

Chemistry: Faculty Publications and Other Works

In single-molecule transistors, we observe inelastic cotunneling features that correspond energetically to vibrational excitations of the molecule, as determined by Raman and infrared spectroscopy. This is a form of inelastic electron tunneling spectroscopy of single molecules, with the transistor geometry allowing in situ tuning of the electronic states via a gate electrode. The vibrational features shift and change shape as the electronic levels are tuned near resonance, indicating significant modification of the vibrational states. When the molecule contains an unpaired electron, we also observe vibrational satellite features around the Kondo resonance.

A Performance And Schedulability Analysis Of An Autonomous Mobile Robot, Ala' Adel Qadi, Steve Goddard, Jiangyang Huang, Shane Farritor

School of Computing: Technical Reports

We present an autonomous, mobile, robotics application that requires dynamic adjustments of task execution rates to meet the demands of an unpredictable environment. The Robotic Safety Marker (RSM) system consists of one lead robot, the foreman, and a group of guided robots, called robotic safety markers (a.k.a., barrels). An extensive analysis is conducted of two applications running on the foreman. Both applications require adjusting task periods to achieve desired performance metrics with respect to the speed at which a system task is completed, the accuracy of RSM placement, or the number of RSMs controlled by the foreman. A static priority …

Positive Self-Talk Statements As A Self-Esteem Building Technique Among Female Survivors Of Abuse., Fred Jackson Teaster Iii

Electronic Theses and Dissertations

The purpose of this integrated review of literature was to explore the relationship between and among females in abusive relationships, self-esteem, and positive self-talk. Various models are discussed that provide possible explanations in the understanding of the complex social and psychological nature of cyclic abuse. These models are: learned helplessness, psychological entrapment, self-verification theory, and feminist theory. It is suggested that positive self-talk statements used by the female survivor as a basis for cognitive restructuring can act as a self-esteem building technique, thus promoting healthier cognitions over time. Furthermore, it is argued that self-esteem enhancement can assist females in developing …

Dose-Dependent Effects Of Salmon Calcitonin On Bone Turnover In Ovariectomized Rats., Beatrice H. Owens

Electronic Theses and Dissertations

In the United States, osteoporosis results in about 1.5 million annual fractures, costing approximately $15 billion. Calcitonin is safe and effective in slowing osteoporotic bone loss, but its effect is transient. The current studies were designed to explore the dose-dependent effects of salmon calcitonin on bone turnover in ovariectomized rats and to determine if the decrease in therapeutic effectiveness of calcitonin demonstrated over time with higher doses is due to oversuppression of bone turnover. Doses of 5, 15, & 50 IU/kg BW/day of calcitonin were compared to placebo in 12-week-old ovariectomized and sham-ovariectomized Sprague-Dawley rats for 24 weeks. The spinal …

Resorts In Southern Appalachia: A Microcosm Of American Resorts In The Nineteenth And Early Twentieth Centuries., Mary F. Fanslow

Electronic Theses and Dissertations

Five resorts in East Tennessee--Montvale Springs and the Wonderland Hotel in the Smokies, Tate Spring in the Holston River Valley, Unaka Springs on the Nolichucky River, and the Cloudland Hotel at the summit of Roan Mountain--stand testament to the proposition that their region engaged fully with areas outside southern Appalachia. Their origins, clientele, and health and leisure offerings followed those of other resorts of the same time period. Moreover, the effects of national socioeconomic trends on the hotels serve as a contradiction to the stereotype of southern Appalachia as an isolated region barricaded from the outside world by mountainous topography. …

Burial Practices In Southern Appalachia., Donna W. Stansberry

Electronic Theses and Dissertations

This study was conducted in an attempt to determine whether certain burial practices are unique to the people of Southern Appalachia. Eight individuals were interviewed, including a minister and a funeral director. As a result of the research, it was found that, although a strong sense of community and religion still prevails, making certain burial rituals distinctive to the people of Southern Appalachia, they are slowly eroding due to the growing presence of the modern American funeral industry.

Qualitative research methods were used to analyze a segment of the Southern Appalachian population, with literature reviews of related material and in-depth …

Variable Resolution Discretization In The Joint Space, Christopher K. Monson, Kevin Seppi, David Wingate, Todd S. Peterson

Faculty Publications

We present JoSTLe, an algorithm that performs value iteration on control problems with continuous actions, allowing this useful reinforcement learning technique to be applied to problems where a priori action discretization is inadequate. The algorithm is an extension of a variable resolution technique that works for problems with continuous states and discrete actions. Results are given that indicate that JoSTLe is a promising step toward reinforcement learning in a fully continuous domain.
