Localized Quantum States, Francois Ziegler

Mathematical Sciences: Faculty Publications

Let X be a symplectic manifold and Aut(L) the automorphism group of a Kostant-Souriau line bundle on X. *Quantum states for X*, as defined by J.-M. Souriau in the 1990s, are certain positive-definite functions on Aut(L) or, less ambitiously, on any "large enough" subgroup G of Aut(L). This definition has two major drawbacks: when G=Aut(L) there are no known examples; and when G is a Lie subgroup the notion is, as we shall see, far from selective enough. In this paper we introduce the concept of a quantum state *localized at Y*, where Y is a coadjoint orbit of a …

Dipole Bound Excited States Of Polycyclic Aromatic Hydrocarbons Containing Nitrogen And Their Relation To The Interstellar Medium, Mallory L. Theis

Honors College Theses

Polycyclic aromatic hydrocarbons (PAHs) are the most abundant type of molecule present in the interstellar medium (ISM). It has been hypothesized that nitrogen replacement within a ring is likely for PAHs present in the ISM. Additionally, electrons, protons, and hydrogen atoms are readily added to or removed from PAHs creating a truly diverse set of chemistries in various interstellar regions. The presence of a nitrogen within a PAH (called a PANH herein) that is additionally dehydrogenated leads to a neutral radical with a large dipole moment. It has recently been shown through the use of high-level quantum chemical computations for …

Detection Of Heavy Transition Metal Cations Using Novel Chemosensors, Shannon Rhodes

Honors College Theses

Transition metals (TM) are found in the environment and living systems. When present in excess, these metals can trigger health problems, which include memory loss and cognitive functions. In this project, commercially-available compounds were used to aid in the making of novel mono- and di-triazole molecular sensors with a well-known reaction called “click chemistry”. These sensors were used efficiently and selectively to attract a specific metal like iron III, copper, and zinc. Six sensors were tested via UV-spectroscopy, NMR, and fluorescence with the cations and selectivity increased as the sensors were altered.

Spontaneous Emission Of Electric And Magnetic Dipoles In The Vicinity Of Thin And Thick Metal, Rabia Hussain, David Keene, Natalia Noginova, Maxim Durach

Physics & Astronomy: Faculty Publications

Strong modification of spontaneous emission of Eu3+ ions placed in close vicinity to thin and thick gold and silver films was clearly demonstrated in a microscope setup separately for electric and magnetic dipole transitions. We have shown that the magnetic transition was very sensitive to the thickness of the gold substrate and behaved distinctly different from the electric transition. The observations were described theoretically based on the dyadic Green’s function approach for layered media and explained through modified image models for the near and far-field emissions. We established that there exists a “near-field event horizon”, which demarcates the distance from …

Parent Preferred Teacher Qualities: The Call For Highly Qualified Teachers, Taylor M. Roberson

Honors College Theses

This study sought to answer the question, “What teacher characteristics do parents value most?” as an initial response to the No Child Left Behind Act of 2001.The purpose of this study was to determine what teacher characteristics parents perceive as making teachers highly qualified to be used to improve parent-teacher relations and teacher effectiveness. To answer this question, a survey was used to collect data from the parents of K-5 students. 176 surveys were returned out of the 800 administered and were used to help the researcher conclude that there is not a teacher characteristic that stands alone to make …

A Morphological And Genetic Analysis Of Forensically Important Blow Flies, From Georgia: The Genus Lucilia, Katie S. Googe

Honors College Theses

Identification of Blow flies (Diptera: Calliphoridae) to species is important for estimating postmortem intervals, because insect species develop at different rates. Three Blow fly species in Georgia; Lucilia coeruleiviridis, L. cuprina, and L. sericata are similar morphologically, making identification difficult. Furthermore, the status of L. cuprina is in doubt; this species may be a complex of true L. cuprina, and L. cuprina x L. sericata hybrids. The objective of this study was to survey the Georgia Blow fly community and validate the statuses of L. coeruleiviridis, L. cuprina, and L. sericata, through morphological and …

Analysis Of Resource Allocation Through Game Theory, Brittney L. Benzio

Honors College Theses

Game theory presents a set of decision-makers in a model in order to simulate how they will interact according to a set of rules. The game is set up with a set of players, actions, and preferences. The model allows each player to, in some way, be affected by the actions of all players. Nash equilibrium illustrates that the best action for any given player depends on the other players’ actions, and so, each player must make some assumption about what the competition will do. The goal of this project is to model situations of different car companies to improve …

Photodynamic Cancer Therapy A Study Of The Photolysis Reaction Between Porphyrin And 9,10-Diphenylanthracene, James Z. Akins

Honors College Theses

Photodynamic therapy (PDT) is a method of combating cancerous tumors. PDT works when certain molecules called photosensitizers absorb light and transfer that energy to dissolved oxygen in solution. Next, this singlet oxygen will interfere with nearby molecules that are necessary for cancer cells to function. This research focuses on the kinetics (rates) of the reaction with respect to the photosensitizer, light, and the target molecule. A laser set at 514nm was used in photolysis with the photosensitizer 5,10,15,20-Tetrakis(2,3,5,6-tetrafluorophenyl)porphyrin (TPP). To mimic cancer cells and monitor the effectiveness of the chosen photosensitizer, 9,10-Diphenylanthracene (DPA) was used as the target molecule. In …

Teachers’ Perceptions Of Scripted Education, Alexa M. Lowery

Honors College Theses

The purpose of my study was to investigate teachers’ perceptions of scripted techniques using state mandated standards and the techniques’ impact on student performance. I surveyed the teachers of elementary schools in Edwards County (pseudonym) and found that most teachers are not using the standards as they were originally intended, and they feel that students are falling behind because the standards are not developmentally appropriate.

Do Omnivorous Shrimp Influence Mayfly Nymphs In A Tropical Island Stream?, Nicholas A. Macías, Jose Checo Colón-Gaud, Jonathan W. Duggins, Alonso Ramírez

Biology: Faculty Publications

Interspecific interactions can play an important role in determining habitat selection and resource use between competing species. We examined interactions between an omnivorous shrimp and a grazing mayfly, two co-dominant taxa found in Puerto Rican headwater streams, to assess how predator presence may influence mayfly resource use and instantaneous growth in a tropical rainforest ecosystem. We conducted a series of behavioral and growth experiments to determine the effects of the freshwater shrimp, Xiphocaris elongata, on the growth rate and resource selection of mayfly nymphs in the family Leptophlebiidae. For resource choice assessments, we conducted a series of five day laboratory …

Fabricating Microfluidic Valve Master Molds In Su‐8 Photoresist, Aaron Dy, Alin Cosmanescu, James Sluka, James Glazier, Dwayne Stupack, Dragos Amarie

Physics & Astronomy: Faculty Publications

Multilayer soft lithography has become a powerful tool in analytical chemistry, biochemistry, material and life sciences, and medical research. Complex fluidic micro-circuits require reliable components that integrate easily into microchips. We introduce two novel approaches to master mold fabrication for constructing in-line micro-valves using SU-8. Our fabrication techniques enable robust and versatile integration of many lab-on-a-chip functions including filters, mixers, pumps, stream focusing and cell-culture chambers, with in-line valves. SU-8 created more robust valve master molds than the conventional positive photoresists used in multilayer soft lithography, but maintained the advantages of biocompatibility and rapid prototyping. As an example, we used …

On The Boundary Blow-Up Solutions Of P(X)-Laplacian Equations With Gradient Terms, Yuan Liang, Qihu Zhang, Chunshan Zhao

Mathematical Sciences: Faculty Publications

In this paper we investigate boundary blow-up solutions of the problem

⎧⎩⎨⎪⎪−△p(x)u+f(x,u)=ρ(x,u)+K(|x|)|∇u|δ(|x|) in Ω, u(x)→+∞ as d(x, ∂Ω)→0,

where −△p(x)u=−div(|∇u|p(x)−2∇u) is called p(x)-Laplacian. The existence of boundary blow-up solutions is proved and the singularity of boundary blow-up solution is also given for several cases including the case of ρ(x,u) being a large perturbation (namely, ρ(x,u(x))f(x,u(x))→1 as x→∂Ω). In particular, we do not have the comparison principle.

Continuous Improvement In The Assessment Process Of Engineering Programs, Youakim Kalaani, Rami J. Haddad

Electrical & Computer Engineering: Faculty Publications

In this paper, we present a multifaceted assessment process that was developed for our Electrical Engineering (EE) program at Georgia Southern University to meet the ABET criteria dealing with the student learning outcomes (SLOs). Both direct and indirect measures were used to collect and analyze data to assess the attainments of the student learning outcomes. To ensure data integrity, multiple faculty were involved in the development of a set of rubrics with benchmarks and performance indicators at both the program and curriculum levels. These tools provided action plans for this continuous improvement process to be implemented during the academic year. …
