Local Quantum Protocols For Separable Measurements With Many Parties, Scott M. Cohen

Physics Faculty Publications and Presentations

In a recent paper [ S. M. Cohen Phys. Rev. A 84 052322 (2011)], we showed how to construct a protocol for implementing a bipartite, separable quantum measurement using only local operations on subsystems and classical communication between parties (LOCC) within any fixed number of rounds of communication, whenever such a protocol exists. Here, we generalize that construction to one that applies for any number of parties. One important observation is that the construction automatically determines the ordering of the parties' measurements, overcoming a significant apparent difficulty in designing protocols for more than two parties. We also present various other …

Classical Political Philosophy And Modern Democracy, Rebekkah Brainerd

University Honors Theses

This paper will be looking at the classical political theories of Plato, Aristotle and Thucydides on democracy to prove they are still relevant and applicable, as well as looking into the problem of democratic corruption. This paper will be split into three sections. The first section will explore these philosophers' theories on different types of constitutions and explore what forms the basis for their theories upon democracy. The second section will develop an applicable "classical political theory on democracy," distilled from these authors' arguments. The final section will be applying classical political theory to contemporary American trends to show how …

Innovation Measurement: A Decision Framework To Determine Innovativeness Of A Company, Kenny Phan

Dissertations and Theses

Innovation is one of the most important sources of competitive advantage. It helps a company to fuel the growth of new products and services, sustain incumbents, create new markets, transform industries, and promote the global competitiveness of nations. Because of its importance, companies need to manage innovation. It is very important for a company to be able to measure its innovativeness because one cannot effectively manage without measurement. A good measurement model will help a company to understand its current capability and identify areas that need improvement.

In this research a systematic approach was developed for a company to measure …

Nonlinearity Analysis And Predistortion Of 4g Wireless Communication Systems, Xiao Li

Dissertations and Theses

The nonlinearity of RF power amplifiers (PA) is one of critical concerns for RF designers because it causes spectral regrowth related to in-band and out-of-band spurious emissions control in communication standards. Traditionally, RF power amplifiers must be backed off considerably from the peak of their power level in order to prevent spectral regrowth. The digital predistortion (DPD) technique is being widely used for compensation of the nonlinearity of RF power amplifiers, as the high power efficiency becomes increasely important in wireless communication systems.

However, the latest generations of communication systems, such as Wi-Fi, WiMAX, and LTE, using wider bandwidth have …

Why Ask Why: An Exploration Of The Role Of Proof In The Mathematics Classroom, Joanna Rachel Bartlo

Dissertations and Theses

Although proof has long been viewed as a cornerstone of mathematical activity, incorporating the mathematical practice of proving into classrooms is not a simple matter. In this dissertation I aim to advance research on proof by addressing this issue. In particular, I explore the role proof might play in promoting the learning of mathematics in the classroom. I do this in a series of three articles (organized as three chapters), which are preceded by an introductory chapter. The introductory chapter situates the remaining chapters in the context of mathematics education research. In the second chapter I explore what the literature …

Photonic Near-Field Imaging In Multiphoton Photoemission Electron Microscopy, Joseph Fitzgerald, Robert Campbell Word, S. D. Saliba, Rolf Kӧnenkamp

Physics Faculty Publications and Presentations

We report the observation of optical near fields in a photonic waveguide of conductive indium tin oxide (ITO) using multiphoton photoemission electron microscopy (PEEM). Nonlinear two-photon photoelectron emission is enhanced at field maxima created by interference between incident 410-nm and coherently excited guided photonic waves, providing strong phase contrast. Guided modes are observed under both transverse magnetic field (TM) and transverse electric field (TE) polarized illuminations and are consistent with classical electromagnetic theory. Implications on the role of multiphoton PEEM in optical near-field imaging are discussed.

Extending Technology Roadmap Through Fuzzy Cognitive Map-Based Scenarios: The Case Of The Wind Energy Sector Of Pakistan, Muhammad Amer

Dissertations and Theses

In this modern era, energy is a key element required for sustainable development and prosperity of a society. Pakistan is an energy deficient country facing problems due to the shortage of over 4000 MW of electricity. The national energy sector is heavily dependent on imported fossil-fuel resources. The energy crisis is negatively affecting all economic and business activities, and it is widely recognized as a severe obstacle to growth and poverty reduction in the country. Establishment of wind farms can help to overcome the energy crisis.

In this research, a national level wind energy roadmap is developed through scenario planning. …

Exploring The Application Of Reconstructability Analysis To Behavior Expression Data From A Social Network, Martin Zwick, Teresa D. Schmidt

Student Research Symposium

Reconstructability analysis (RA) is proposed as a complementary method for evaluating social network-related phenomena. Longitudinal records of social behavior expression among members of a social network are commonly represented as a set of social network analysis (SNA) connections, but might also be usefully represented as a set of associations derived through RA methods. Reconstructability Analysis identifies individuals as being associated when their behavior patterns appear coordinated–a representation that is unavailable with standard SNA. To explore the potential usefulness of RA for analyzing social behaviors, simulated behavior patterns were evaluated with both SNA and RA, and the results were compared. Several …

Computational Capabilities Of Leaky Integrate-And-Fire Neural Networks For Liquid State Machines, Amin Almassian, Christof Teuscher

Student Research Symposium

We analyze the computational capability of Leaky Integrate-and-Fire (LIF) Neural Networks used as a reservoir (liquid) in the framework of Liquid State Machines (LSM). Maass et. al. investigated LIF neurons in LSM and their results showed that they are capable of noise-robust, parallel, and real-time computation. However, it still remains an open question how the network topology affects the computational capability of a reservoir. To address that question, we investigate the performance of the reservoir as a function of the average reservoir connectivity. We also show that the dynamics of the LIF reservoir is sensitive to changes in the average …

Differential Effects Of Membrane Order On Membrane Permeability, Miranda J. Bradley, Marshall J. Colville, Miles J. Crumley, Drake C. Mitchell

Student Research Symposium

Phospholipid membranes segregate into lateral domains of liquid ordered (lo) and liquid disordered (ld) phases when cholesterol and mixed species of lipids with saturated and unsaturated acyl chains are present. To examine membrane permeability and rate of vesicle rupture by Triton in pure lo, pure ld, and mixed lo/ld phases, LUVs were prepared based on the ternary phase diagram of POPC, sphingomyelin, and cholesterol. These LUVs were loaded with 2mM carboxyfluorescein (CF) and formed by extrusion at 65oC. Using a stopped-flow fluorometer, changes in CF fluorescence were measured when LUVs were exposed to sudden osmotic gradients, pH gradients, or 0.1% …

Training An Asymmetric Signal Perceptron In An Artificial Chemistry, Peter Banda

Student Research Symposium

Autonomous learning implemented purely by means of a synthetic chemical system has not been previously realized. Learning promotes reusability, and minimizes the system design to simple input-output specification. In this poster, I present a simulated chemical system, the first full-featured implementation of a perceptron in an artificial (simulated) chemistry, which can successfully learn all 14 linearly separable logic functions. A perceptron is the simplest system capable of learning inspired by the functioning of a biological neuron. My newest model called the asymmetric signal perceptron (ASP) is, as opposed to its predecessors such as the weight-race perceptron (WRP), substantially simpler by …

Finding Rna-Dna Hybrid Viruses, Jeremy Filip, Geoffery S. Diemer, Kenneth M. Stedman

Student Research Symposium

Until extremely recently it was thought that recombination between DNA and RNA viruses was practically nonexistent. The discovery of the "RNA-DNA Hybrid Virus" (RDHV) genome in a metavirome from a hightemperature acidic lake changed this view (Diemer and Stedman, 2012). We, and others, have discovered multiple examples of this recombination "hiding in plain sight" in multiple both published and unpublished metagenomes from many different environments and recent publications (Rosario et al., 2012 a Tae Woong Whon et al, 2012, Mitsuhiro Yoshida et al., 2013, and several others through personal communication). Comparing the proteins within these hybrid viruses against each other …

An Alternative Ribozyme For The Rna Hypercycle, Ishak Elkhal

Student Research Symposium

In the quest to forward understanding of the prebiotic world (specifically, the RNA World Hypothesis), one of the most interesting paradigms to consider is the potential for cooperative networks that may have driven molecular evolution forward. Such a network may exist as an RNA hypercycle, as proposed by Eigen (1977). Much progress has been made towards an RNA hypercycle-like system, especially using the Azoarcus ribozyme system demonstrated by Vaidya et al. (2012). The current work is dedicated to constructing a second model as a cooperative RNA network, utilizing a group I intron from Coxiella burnetii (Cbu1917). The intron was constructed …

Mathematics Orality And Literacy, Beverly Orth

Student Research Symposium

To become a mathematician, a student must learn how to "do" mathematics and also how to communicate with other mathematicians. Through a special language, both oral and written, mathematicians share a discourse community. This community extends not only across the boundaries of natural language, but also across centuries. My paper explores the following question: How does a person enter the discourse community of mathematicians? My research shows that learning mathematics parallels the learning of natural language reading and writing. Much like learning a foreign language, learning mathematics has been based mostly on oral tradition. The orality of mathematics learning is …
