Krf Excimer Laser-Assisted Combustion-Flame Deposition Of Diamond Films, Y. X. Han, Hao Ling, Yongfeng Lu

Department of Electrical and Computer Engineering: Faculty Publications

Cobalt (Co) composition has detrimental effects on the deposition of diamond films on cemented tungsten carbide (WC-Co) substrates. It decreases adhesion of the deposited films to the substrates and causes a transformation of sp³-bonded diamond to sp²-bonded graphite. In this study, a KrF excimer laser with a wavelength of 248 nm, a pulse width of 23 ns, and a pulse energy range of 84–450 mJ was used in the combustion-flame method to improve the quality of the deposited diamond films. Scanning electron microscopy, energy dispersive x-ray analysis, and Raman spectroscopy of the deposited films showed that …

The All Boron Carbide Diode Neutron Detector: Comparison With Theory, A. N. Caruso, Peter A. Dowben, S. Balkir, Nathan Schemm, Kevin Osberg, R.W. Fairchild, Oscar Barrios Flores, Snjezana Balaz, A.D. Harken, Brian W. Robertson, Jennifer I. Brand

Peter Dowben Publications

A boron carbide diode detector, fabricated from two different polytypes of semiconducting boron carbide, will detect neutrons in reasonable agreement with theory. Small deviations from the model calculations occur due to the detection efficiencies of the ¹⁰B capture products Li plus α sum signal differing somewhat from expectation in the thin diodes. The performance of the all boron carbide neutron detector does depart from the behavior of devices where a boron rich neutron capture layer is distinct from the diode charge collection region (i.e. a conversion layer solid state detector), as is expected.

The Meaning Of “Life”: The Morning-After-Pill, The Question Of When Life Begins, And Judicial Review, Jason M. Horst

ExpressO

The Article foresees that certain state legislation limiting access to the morning-after-pill will thrust the question of when life begins onto the courts. This is due both to fact that the morning-after-pill has the potential to act at a point when the existence of potential life is in dispute and largely a matter of belief and to the fact that the constitutionality of the legislation may depend on whether courts consider the morning-after-pill abortion or contraception.

The Article argues that courts should address the question of whether to consider the morning-after-pill abortion or contraception by attempting to adopt and apply …

The Central Laser Facility At The Pierre Auger Observatory, B. Fick, M. Malek, J. A.J. Matthews, J. Matthews, R. Meyhandan, M. Mostafá, M. Roberts, P. Sommers, L. Wiencke

Faculty Publications

The Central Laser Facility is located near the middle of the Pierre Auger Observatory in Argentina. It features an ultraviolet laser and optical components that direct a beam of calibrated, pulsed light into the sky. Light scattered from this beam produces tracks in the Auger optical detectors, which normally record nitrogen fluorescence tracks from cosmic ray air showers. The Central Laser Facility acts as a "test beam" that is used to investigate properties of the atmosphere and the air fluorescence detectors. Additionally, the laser can send a light pulse via optical fiber to the nearest surface detector tank. This signal, …

Agronomic And Quality Effects In Winter Wheat Of A Gene Conditioning Resistance To Wheat Streak Mosaic Virus, L. A. Divis, R. A. Graybosch, C. J. Peterson, P. Stephen Baenziger, G. L. Hein, B. B. Beecher, T. J. Martin

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Wheat streak mosaic virus (WSMV) is one of the most important diseases limiting winter wheat (Triticum aestivum L.) production in the western Great Plains of North America. There is no known effective WSMV resistance within the primary gene pool of wheat. However, a resistance gene (Wsm1) has been transferred to wheat from a perennial relative, intermediate wheat-grass [Thinopyrum intermedium (Host) Barkworth & DR Dewey]. Nebraska-adapted winter wheat lines carrying Wsm1 were used to characterize the effects of this alien introgression on agronomic and quality traits. Sister-lines from six breeding populations were evaluated under virus-free conditions, …

Linking Bacterioplankton Community Structures To Environmental State Variables And Phytoplankton Assemblages In Two South Carolina Salt Marsh Estuaries, Wes Johnson, Alan J. Lewitus, Madilyn Fletcher

Faculty Publications

Microorganisms are among the most important organisms to the ecology of salt marsh estuaries; however, fundamental questions regarding their distribution, environmental controls, and interactions with phytoplankton remain unanswered. We used denaturing gradient gel electrophoresis (DGGE) of bacterial rRNA genes and high performance liquid chromatography (HPLC) of phytoplankton photopigments to characterize planktonic communities from the Ashepoo, Combahee, and Edisto (ACE) Basin and North Inlet (NI) estuaries on the South Carolina coast, USA. Multivariate comparisons of the planktonic community profiles revealed that the 2 estuaries supported distinct bacterial communities. Furthermore, bacterial communities in both systems were partitioned into separate particle-associated (PA) and …

Energetics Of Oxaspirocycle Prototypes: 1,7-Dioxaspiro[5.5]Undecane And 1,7,9-Trioxadispiro[5.1.5.3]Hexadecane, Abby Jones Weldon, Gregory S. Tschumper

Chemistry Faculty Research & Creative Works

(Chemical Equation Presented) The relative gas-phase energetics of several low-lying isomers of 1,7-dioxaspiro[5.5]undecane and 1,7,9-trioxadispiro[5.1.5. 3]hexadecane have been calculated with second-order Møller-Plesset perturbation theory and basis sets as large as aug-cc-pVQZ. Relative energies in THF, dichloromethane, acetone, and DMSO have been estimated with corrections from polarized continuum model calculations at the B3LYP/6-311+G(d) level. In the most stable conformation of 1,7-dioxaspiro[5.5]undecane, both rings adopt chair conformations, and both oxygens are axially disposed (2A). It is more than 2 kcal mol^-1 more stable than all the other conformers. In agreement with previous work, the "twist-boat" trans isomer (3A) is the most …

Fluorescence Blinking Statistics From Cdse Core And Core/Shell Nanorods, S. Wang, C. Querner, Thomas B. Emmons , '08, M. Drndic, Catherine Hirshfeld Crouch

Physics & Astronomy Faculty Works

We report fluorescence blinking statistics measured from single CdSe nanorods (NRs) of seven different sizes with aspect ratios ranging from 3 to 11. This study also included core/shell CdSe/ZnSe NRs and core NRs with two different surface ligands producing different degrees of surface passivation. We compare the findings for NRs to our measurements of blinking statistics from spherical CdSe core and CdSe/ZnS core/shell nanocrystals (NCs). We find that, for both NRs and spherical NCs, the off-time probability distributions are well described by a power law, while the on-time probability distributions are best described by a truncated power law, P(tau(on)) similar …

Long-Term Neuroadaptations Produced By Withdrawal From Repeated Cocaine Treatment: Role Of Dopaminergic Receptors In Modulating Cortical Excitability, Lourdes Nogueira, Peter W. Kalivas, Antonieta Lavin

MUSC Faculty Journal Articles

Dopamine (DA) modulates neuronal activity in the prefrontal cortex (PFC) and is necessary for optimal cognitive function. Dopamine transmission in the PFC is also important for the behavioral adaptations produced by repeated exposure to cocaine. Therefore, we investigated the effects of repeated cocaine treatment followed by withdrawal (2– 4 weeks) on the responsivity of cortical cells to electrical stimulation of the ventral tegmental area (VTA) and to systemic administration of DA D1 or D2 receptor antagonists. Cortical cells in cocaine- and saline-treated animals exhibited a similar decrease in excitability after the administration of D1 receptor antagonists. In contrast, cortical neurons …

Properties Of Some Matrix Classes In Linear Complementarity Theory., Arup Kumar Das Dr.

Doctoral Theses

The linear complementarity problem is a fundamental problem that arises in optimization, game theory, economics, and engineering. It can be stated as follows:Given a square matrix A of order n with real entries and an n dimensional vector q, find n dimensional vectors w and z satisfying w − Az = q, w ≥ 0, z ≥ 0 (1.1.1) w t z = 0. (1.1.2)This problem is denoted as LCP(q, A). The name comes from the condition (1.1.2), the complementarity condition which requires that at least one variable in the pair (wj , zj ) should be equal to 0 …

A Graph-Theoretic Method For Detecting Potential Turing Bifurcations, Maya Mincheva, Marc R. Roussel

Faculty Articles, Papers, and Other Scholarship

The conditions for diffusion-driven (Turing) instabilities in systems with two reactive species are well known. General methods for detecting potential Turing bifurcations in larger reaction schemes are, on the other hand, not well developed. We prove a theorem for a graph-theoretic condition originally given by Volpert and Ivanova [Mathematical Modeling (Nauka, Moscow, 1987) (in Russian), p. 57] for Turing instabilities in a mass-action reaction-diffusion system involving n substances. The method is based on the representation of a reaction mechanism as a bipartite graph with two types of nodes representing chemical species and reactions, respectively. The condition for diffusion-driven instability is …
