Embedding Direction Of Arrival And Antenna Beamforming Algorithms On Automated Software Defined Radio Platforms, Adrian J. Lewis

Electrical and Computer Engineering ETDs

Antenna arrays are an essential technology in the modern era in both communications and radar applications. The algorithms used for antenna arrays are beginning to be embedded in smart device applications to enable greater communication abilities. This thesis explores the idea of embedding direction of arrival and beamforming algorithms using a software defined radio platform. Specifically, the Multiple Signal Classification (MuSiC) algorithm and Minimum Variance Distortionless Response (MVDR) algorithm are combined. The combination of similar algorithms has the potential to be used in many internet of things applications to enable more dynamic communication ability.

Full-Length Αiibβ3 Cryo-Em Structure Reveals Intact Integrin Initiate-Activation Intrinsic Architecture, Tong Huo, Hongjiang Wu, Zeinab Moussa, Mehmet Sen, Valerie Dalton, Zhao Wang

Faculty, Staff and Students Publications

Integrin αIIbβ3 is the key receptor regulating platelet retraction and accumulation and a proven drug-target for antithrombotic therapies. Here we resolve the cryoEM structures of the full-length αIIbβ3, which covers three distinct states along the activation pathway. Firstly, we obtain the αIIbβ3 structure at 3Å resolution in the inactive state, revealing the overall topology of the heterodimer with the transmembrane (TM) helices and the ligand-binding domain tucked in a specific angle proximity to the TM region. After the addition of a Mn2+ agonist, we resolve two coexisting structures representing two new states between inactive and active state. Our structures show …

Challenges Of Spatially Resolved Metabolism In Cancer Research, Andrew N. Lane, Richard M. Higashi, Teresa W-M Fan

Markey Cancer Center Faculty Publications

Stable isotope-resolved metabolomics comprises a critical set of technologies that can be applied to a wide variety of systems, from isolated cells to whole organisms, to define metabolic pathway usage and responses to perturbations such as drugs or mutations, as well as providing the basis for flux analysis. As the diversity of stable isotope-enriched compounds is very high, and with newer approaches to multiplexing, the coverage of metabolism is now very extensive. However, as the complexity of the model increases, including more kinds of interacting cell types and interorgan communication, the analytical complexity also increases. Further, as studies move further …

A Sequential Approach To Estimating Bayesian P-Values Through Simulation Studies, Johnpaul Chiemelie Anamege

Electronic Theses and Dissertations Archive

This thesis introduces a novel sequential approach for calculating Bayesian P-values, addressing limitations of traditional frequentist methods. Using Monte Carlo simulations, we investigate the properties of sequentially calculated Bayesian P-values under various conditions, comparing them to frequentist counterparts. Our findings demonstrate advantages including incorporation of prior knowledge, continuous evidence measurement, and adaptability to accumulating data. We explore computational challenges, propose optimized algorithms, and address the impact of prior specification, providing guidelines for choosing appropriate priors. This research contributes to the ongoing discussion about P-values in scientific inference and offers a practical framework for researchers adopting Bayesian methods in sequential analyses. …

The Moderating Effect Of Organizational Identification And Supervisor’S Organizational Embodiment On Unethical Pro- Organizational Behavior, Taylor Morgan Flinn

Theses and Dissertations

Unethical pro-organizational behavior (UPB) are behaviors that are illegal/immoral but are engaged in with the intention of benefiting their organization. The present study sought to investigate the moderating relationships of organizational identification (OI) and supervisor’s organizational embodiment (SOE), with work engagement as a predictor. The results revealed that there was a weak correlation between work engagement and UPB as well as SOE and UPB. Both OI and SOE did not moderate the relationship between work engagement and UPB. The current study contributed to the literature on predictors of UPB, as work engagement has rarely been used as a predictor of …

Case Report: Intrafraction Dose-Guided Tracking For Gastrointestinal Organ-At-Risk Isotoxicity Delivery On An Mr-Guided Radiotherapy System, Sreenija Yarlagadda, Yonatan Weiss, Michael Chuong, Nema Bassiri Gharb, Alonso Gutierrez, Rupesh Kotecha, Minesh Mehta, Kathryn Mittauer

All Publications

In the current era of high-precision radiation therapy, real-time magnetic resonance (MR)-guided tracking of the tumor and organs at risk (OARs) is a novel approach that enables accurate and safe delivery of high-dose radiation. Organ tracking provides a general sense of the need for daily online adaptation but lacks precise information regarding exact dosimetry. To overcome this limitation, we developed the methodology for monitoring intrafraction motion with real-time MR-guided isodose line-based tracking of an OAR in combination with anatomic tumor-based tracking and reported the first case treated with this approach. An isolated para-aortic (PA) nodal recurrence from carcinosarcoma of the …

Study The Global Earthquake Patterns That Follow The St. Patrick’S Day Geomagnetic Storms Of 2013 And 2015, Dimitar Ouzounov, Galina Khachikyan

Mathematics, Physics, and Computer Science Faculty Articles and Research

A response of global seismic activity to the geomagnetic storms of St. Patrick’s Day (March 17) in 2013 and 2015 is investigated. These two storms occurred during nearly identical storm sudden commencement times and similar solar flux levels. We have revealed a rather similar pattern of the most substantial earthquakes that have occurred since these storms. Two major crust continental earthquakes, in Iran (M = 7.7), 16 April 2013, and in Nepal (M = 7.8), 25 April 2015, have occurred with a time delay of ~30 and ~39 days after geomagnetic storm onsets in 2013 and 2015, respectively. After that, …

P-Adic Quantum Mechanics, The Dirac Equation, And The Violation Of Einstein Causality, Wilson A. Zuniga-Galindo

School of Mathematical & Statistical Sciences Faculty Publications

This article studies the breaking of the Lorentz symmetry at the Planck length in quantum mechanics. We use three-dimensional ℘-adic vectors as position variables, while the time remains a real number. In this setting, the Planck length is 1/℘, where ℘ is a prime number, and the Lorentz symmetry is naturally broken. In the framework of the Dirac-von Neumann formalism for quantum mechanics, we introduce a new ℘-adic Dirac equation that predicts the existence of particles and antiparticles and charge conjugation like the standard one. The discreteness of the ℘-adic space imposes substantial restrictions on the solutions of the new …

Automated Customer Assistance Is Not Customer Service, Chris Roberts Phd, Lisa Young Phd, Misty M. Johanson Phd, Mary Jo Dolasinski Phd

ICHRIE Research Reports

For development of the theory of service, the focus is on the constructs of service. The theory is expanded to encompass the various business models of service and the service encounter including but not limited to guest satisfaction, service quality, service and technology, service system design, and customer relationship management. Consideration is given to the aspects of the service transaction and what constitutes service, where a labor component of a firm’s product has been transferred to the customer. Lastly, self-service and automation are considered in the context of the user experience. A model of the theory of service is presented.

Rupert Murdoch: Altruism Inverted, Elizabeth Summerfield

The Journal of Values-Based Leadership

American entrepreneur, television producer, media owner and philanthropist, Ted Turner, once described Rupert Murdoch as “the most dangerous man in the world” (Beahm, 1). This is not an unusual judgement. But it is also one which may contribute to sustaining the Murdoch “brand”, his notoriety and appeal to supporters.

This article examines the deep origins of Murdoch’s cynical worldview, and the source of an ambition that drove him from ownership of a small provincial Australian newspaper to global media mogul. What compelled the need to disseminate often dangerously divisive views on as large a stage as possible, while purporting to …

Focusing on the value system, this small-scale study explored the change in values and perceptions of a disaster-affected mountain community about natural hazards and its implications for their future lives. Twenty participants from the affected community, including local political activists, religious leaders, teachers, and youth activists, were thoroughly interviewed. The study explored significant deviations from their traditional values of connectedness to each other and with their ancestors' land. The …

Running A Business Like A Biblical Prophet: What Would Isaiah, Hosea, Amos, Or Ezekiel Do?, Hershey H. Friedman, Joshua Krausz

The Journal of Values-Based Leadership

This paper contends that a toxic corporate culture is the leading cause of unethical behavior in business, and that biblical values taught by the ancient prophets can help transform a firm's culture, inspire employees, and foster a work environment where the paycheck is not the ultimate goal. Scripture could help employees understand that the organization's purpose is to achieve many positive outcomes, such as delivering value to the customer, making a positive difference in society and the world, alleviating poverty and hunger, providing meaningful work, and encouraging innovation and positive change.

How Ballot Measure Wording Affects Preference-Consistent Voting: Experimental Evidence From The United States, William M. Pierce

Political Science Honors Projects

Why do some people vote for ballot measures that are inconsistent with their policy preference while others do not? It is important to explore this question in order to understand how well direct democracy translates the will of the people into policy outcomes. Drawing on electoral theories and cognitive science, I hypothesize that people are more likely to vote against their policy preferences when the language of a ballot measure is more complex. I test this hypothesis, along with causal mechanisms and heterogeneous treatment effects, using a survey experiment on a quasi-representative sample of voters in the United States.
