Waveguiding Of Surface Phonon Polariton, Franklin Manene, Brian A. Lail, Edward C. Kinzel

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Metal losses lead to unacceptably low propagation lengths in THz and LWIR waveguides. While SPP based waveguides provide relatively good confinement and attenuation in the near-IR and visible these are insufficiently bound to the surface in the THz and LWIR. We study using surface phonon polaritons for waveguiding at these frequencies. An eigenmode approach was applied to model a hybrid waveguide structure at λ=10.6 μm. The results show that phonon-coupled hybrid waveguide of silicon carbide BCB and gold exhibit enhanced propagation length and confinement at LWIR. © 2013 IEEE.

Using Resonance Raman Cross-Section Data To Estimate The Spin State Populations Of Cytochromes P450, Piotr J. Mak, Qianhong Zhu, James R. Kincaid

Chemistry Faculty Research and Publications

The cytochromes P450 (CYPs) are heme proteins responsible for the oxidation of xenobiotics and pharmaceuticals and the biosynthesis of essential steroid products. In all cases, substrate binding initiates the enzymatic cycle, converting ferric low-spin to high-spin state, with the efficiency of the conversion varying widely for different substrates, so documentation of this conversion for a given substrate is an important objective. Resonance Raman (rR) spectroscopy can effectively yield distinctive frequencies for the ν₃ ‘spin state marker’ bands. Here, employing a reference cytochrome P450 (CYP101), the intensities of the ν₃ modes (I_LS) and (I_{HS …}

Three Dimensional Polarization Controllable Electromagnetic Cell, Bo Zhu, Weng Cho Chew, Lijun Jiang

Electrical and Computer Engineering Faculty Research & Creative Works

We demonstrate an electromagnetic (EM) cell that can generate uniform electric field with three dimensional (3D) polarization dynamic control for the EM compatibility/interference (EMC/EMI) testing. 3D orthogonal slotline structures are designed and utilized to build the walls of the EM cell. By feeding the slotlines in phase and terminating them with matching loads, the uniform electric field similar to a standing wave is produced by two slotline modes propagating in opposite directions inside the cell. Microwave switches are integrated into the slotlines so that we can choose the operating slotline dynamically and change its orientation in a 3D manner by …

Modeling Radiated Emissions Through Shielding Boxes Based On The Tangential Electrical Field Samplings Over Openings, Ping Li, Li (Lijun) Jun Jiang

Electrical and Computer Engineering Faculty Research & Creative Works

The radiation from radiators such as PCBs inside an enclosed shielding box with ventilation slots is an important issue for electromagnetic compatibility or interference characterizations. In this paper, a two-step process is proposed based on the equivalence principle and the electric field integral equation method to complete the radiation prediction. The tangential electric fields over the slots on shielding boxes are first sampled to be the equivalent magnetic currents radiated from internal PCBs. In the second step, to avoid the computation of complex nonanalytical dyadic Green's functions when the field radiation is computed directly from the equivalent source, the surface …

Co-Simulation Of Distributive And Lumped Systems Using The Discontinuous Galerkin Time Domain Finite Element Method, Ping Li, Li (Lijun) Jun Jiang

Electrical and Computer Engineering Faculty Research & Creative Works

The signal integrity and power integrity analysis of 3D integrated circuits or other EMC/EMI systems usually separate the lumped circuit modeling and the distributive system modeling. However, due to the high density of integration, it is not proper to separate them in the modeling process anymore. In this paper, a hybrid electromagnetics (EM)-circuit simulator is proposed for incorporating multiport lumped circuit networks through their admittance matrices into the discontinuous Galerkin time-domain finite element method (DGTDFEM). The admittance matrix in the Laplace-domain can be derived analytically or obtained from network parameters such as S-parameters in the frequency domain. To convert frequency …

Modeling Of Crosstalk Between Two Nonparallel Striplines On Adjacent Layers, Songping Wu, Jun Fan

Electrical and Computer Engineering Faculty Research & Creative Works

Crosstalk between two nonparallel strip lines on adjacent layers is investigated. An equivalent per unit length model for nonparallel lines is developed based on multiconductor transmission line theories and the Nelder-Mead optimization algorithm. The physical meaning of the equivalent model is explained for different test geometries. Empirical formulas, as functions of various geometric parameters, are derived based on multivariable curve fitting for a set of defined trace geometries. The validity of the empirical model is confirmed through comparison with different test examples. © 2013 IEEE.

Mutant Drought Phenotype Investigation : A Look Into Effects Of Protein Prenylation On Water Utilization In Conditions Of Varying Soil Saturation And Gene Knockout., Casey Rasmussen

College of Arts & Sciences Senior Theses

Plants respond to environmental stress, such as drought, with increases in levels of Abscisic Acid (ABA). This stress response allows greater survival rates but results in the plants producing lower seed yield and biomass. Certain mutant strains of the Arabidopsis plant have been identified with mutations in coding regions involved in the formation of the α and β subunits of PFT and PGGT-I genes involved in protein prenylation. We explored the possibility of these mutant strains to better preserve seed yield and plant biomass under drought stressing conditions in comparison to the wild type (Columbia) strain, based on the mutants’ …

Influence Of Corruption, Foreign Direct Investment And Net Domestic Credit On Economic Growth, Meng Mi

Applied Economics Theses

In Asia, it is not clear whether governments can attract increased FDI by reducing corruption, or whether corruption is irrelevant to levels of GDP growth, especially if the mechanism of net domestic credit can be used to stimulate economic growth even in the absence of high levels of FDI. The purpose of this study is to examine the potentially distinct effects of both FDI and net domestic credit on economic growth, as well as the relationship between corruption and economic growth. This relationship is studied using ex post facto data from a sample of Asian countries from the years 1980-2012. …

Impact Of Oil Prices Fluctuations On Economies In The Age Of Globalization, Ancel Raynaud Soh Feussi

Applied Economics Theses

Early in the past century, oil has powered economic growth in industrialized economies. Towards the end of the 20^th century, as emerging and underdeveloped economies relied more on oil powered means for their everyday need, their appetite for oil has considerably increased and this put an upward pressure on the global oil demand. As supply now struggles to match demand, oil prices are more and more driven by macroeconomics fundamentals. The disparity between supply and demand has had different effects on economies depending, if it is a net oil-exporting or net oil-importing one. This paper will attempt to quantify …

Preserving Imperial Sovereignty In The Changing Political Order Of Prewar Japan, Shane Vrabel

History Theses

During the nineteenth century, several Western powers began to establish a presence in East Asia through the use of gunboat diplomacy. In 1853, United States Commodore Matthew C. Perry arrived on Japanese shores intent on forcing the ruling Tokugawa Shogunate to end its policy of sakoku (seclusion) and interact with the West through trade. Angered over the policies of the Tokugawa Shogunate, the han (domains) of Chōshū and Satsuma decided to launch the Boshin Civil War by instigating rebellion against the shogun. The military forces of Chōshū and Satsuma eventually captured the imperial capital of Kyoto and the young Prince …

Indira Gandhi: India’S Destined Leader, Josclyn C. Green

History Theses

This thesis explores the life and political career of Indira Nehru Gandhi and analyzes how the historical circumstances of her era shaped her character in a manner that made her uniquely prepared to confront the numerous political challenges that she faced during her tenure as India’s Prime Minister. Indira Nehru Gandhi was Prime Minister of India from 1966 until 1977, and again in 1980 up until her assassination in 1984. Indira Gandhi was seemingly destined to rule over India. She was born into a prominent family who led the way to Indian independence from Great Britain. She was also born …

The Anthropology Of Educational Persistence: What Can We Learn From Anthropology To Improve Educational Opportunities And Outcomes For Underserved Students?, Teresa Mccarty, Bryan Mckinley Jones Brayboy, Amanda Datnow, Edmund T. Hamann, The Anthropology Of Educational Persistence Thought Collective

Department of Teaching, Learning, and Teacher Education: Faculty Publications

In the context of shifting demographics in which more than 50% of the U.S. student population now belongs to a group that formerly would have been classified as “minority,” this report provides evidence from anthropological research on the factors that promote or impede educational persistence, particularly among underserved groups who now constitute the “new majority.” Based on a thorough review of the literature, we offer five principles to guide future research, policy, and practice and offer illustrative examples of each principle. A key insight is that failure is not inevitable for historically underserved groups and that, given that, we must …

X-Ray Fluorescence (Xrf) Analyzer - Theory, Utility, And Qa/Qc For Environmental And Commercial Product Samples In Cambodia, Sereyrath Lim

Multidisciplinary Studies Theses

Laboratory facilities in developed countries provide a variety of options for analysis of environmental samples and commercial commodities that could impact human health. The same is not true in developing countries and there is a great need to identify technologies that could be used to provide robust, accurate, cost-effective analysis that minimizes the need for extensive technical training. An X-ray Fluorescence (XRF) analyzer seems to be an analytical technique that could be such a tool for developing countries. Therefore, the objective of this thesis was to assess the performance and utility of a handheld, portable XRF unit in analyzing different …

Second Nature: An Exploration In Planning And Design For A Place- And Community-Based Museum Process, Erin E. Hicks

Museum Studies Projects

Museums are and have been engaged in a paradigm shift. Much has been written about the social roles of museums and many in the field have sought to define museums, taking a position on why the museum exists, who it is for, and why it continues. Is the museum a temple or a forum? I wondered why it could not be both— and more—more inclusionary, more participatory, and more reflective of community. Could this be the museum of the future? This project explores how a museum transforms both physically and theoretically by applying an educational mission onto a hypothetical museum: …

The Art Of Steel: As Seen Through The Eyes Of Norman Rockwell, Megan S. Hahin

Museum Studies Projects

For this project the author partnered with the Steel Plant Museum of Western New York (SPM) in South Buffalo to create a special exhibition focused on their 14 prints of Norman Rockwell paintings in the museum’s collection. The exhibition used supplementary artifacts to add personal narratives to Rockwell’s paintings. The exhibit diversified the audience of the SPM and created a potential new audience the museum could target, while still appealing to their current audience through the use of personal narrative. The museum had not curated an art exhibition before and this project proved to be beneficial by exploring new themes …

Surface-Enhanced Raman Spectroscopy (Sers) Tracking Of Chelerythrine, A Na+ K+ Pump Inhibitor, Into Cytosol And Plasma Membrane Fractions Of Human Lens Epithelial Cell Cultures, Kevin M. Dorney, Ioana E.P. Sizemore, Tariq Alqahtani, Norma C. Adragna, Peter K. Lauf

Pharmacology and Toxicology Faculty Publications

Background/aims: The quaternary benzo-phenanthridine alkaloid (QBA) chelerythrine (CET) is a pro-apoptotic drug and Na(+)/K(+) pump (NKP) inhibitor in human lens epithelial cells (HLECs). In order to obtain further insight into the mechanism of NKP inhibition by CET, its sub-cellular distribution was quantified in cytosolic and membrane fractions of HLEC cultures by surface-enhanced Raman spectroscopy (SERS). Methods: Silver nanoparticles (AgNPs) prepared by the Creighton method were concentrated, and size-selected using a one-step tangential flow filtration approach. HLECs cultures were exposed to 50 μM CET in 300 mOsM phosphate-buffered NaCl for 30 min. A variety of cytosolic extracts, crude and purified membranes, …

Lawyering Outside The Box: Confronting The Creativity Crisis, Samantha A. Moppett

Southern Illinois University Law Journal

The Great Recession was not only a defining moment in world history and for the United States economy; it was also a turning point for the legal profession.  The economic downturn resulted in a long-term structural adjustment in the legal services market that will adversely impact the legal profession permanently.  Accordingly, lawyers need to be creative in adapting to the changing realities of law practice.

Yet, despite the need for creative approaches to address the changing legal landscape, a disturbing phenomenon was recently identified: creativity in the United States is declining.  Moreover, legal education and the legal practice impose barriers …

Revisiting Colorado V. Connelly: The Problem Of False Confessions In The Twenty-First Century, Daniel Harkins

Southern Illinois University Law Journal

This Article analyzes how the current constitutional test formatted in Colorado v. Connelly no longer sufficiently excludes unreliable confessions from being admitted into evidence at trial.  In the last twenty years, a multitude of psychological studies have demonstrated that people confess to crimes they did not commit for a range of reasons wider than what is recognized by the Connelly inquiry.  This Article analyzes this phenomenon and examines potential methods (both inside and outside the constitutional standard) for preventing these confessions from reaching juries at trial.
