One-Note-Samba Approach To Cosmology, Florentin Smarandache, Victor Christianto

Branch Mathematics and Statistics Faculty and Staff Publications

Inspired by One Note Samba, a standard jazz repertoire, we present an outline of Bose-Einstein Condensate Cosmology. Although this approach seems awkward and a bit off the wall at first glance, it is not impossible to connect altogether BEC, Scalar Field Cosmology and Feshbach Resonance with Ermakov-Pinney equation. We also briefly discuss possible link with our previous paper which describes Newtonian Universe with Vortex in terms of Ermakov equation.

Optimal Control Strategies For Complex Biological Systems, Afroza Shirin

Mechanical Engineering ETDs

To better understand and to improve therapies for complex diseases such as cancer or diabetes, it is not sufficient to identify and characterize the interactions between molecules and pathways in complex biological systems, such as cells, tissues, and the human body. It also is necessary to characterize the response of a biological system to externally supplied agents (e.g., drugs, insulin), including a proper scheduling of these drugs, and drug combinations in multi drugs therapies. This obviously becomes important in applications which involve control of physiological processes, such as controlling the number of autophagosome vesicles in a cell, or regulating the …

A Machine Learning Based Framework For Load Forecasting And Optimal Operation Of Power Systems With Distributed Generation, Tairen Chen

Electrical and Computer Engineering ETDs

The fast development and wide utilization of distributed generations (DGs), such as Photovoltaic panels and wind turbines, provide environmentally friendly renewable energy. However, inappropriate operation, sizing, and placement of DGs could increase the power losses and reduce the stability of the power network. Load forecasting is critical to the electrical utilities to schedule power generation and distribution. In this dissertation, a framework is proposed for load forecasting and optimal operation of power system with DGs in the distribution feeder-level.

In the first part, a nonparametric method, the Bayesian Additive Regression Trees (BART), is introduced for day-ahead peak load forecasting. The …

Detection And Remodeling Of Toxic Amyloid Aggregates By Novel Conjugated Polyelectrolytes, Adeline Marianne Fanni

Biomedical Engineering ETDs

The abnormal misfolding and aggregation of intrinsically disordered proteins into ordered fibrillar amyloid aggregates is recognized as a common pathological event in neurodegenerative disorders (ND) such as Alzheimer’s and Parkinson’s diseases. The key role of fibrillar and pre-fibrillar aggregates in ND makes them ideal biomarkers to better understand disease progression but also for early disease detection and therapeutic intervention. The work described herein was conducted to gain a better understanding of amyloid interaction to lipid membrane and its role in peptide toxicity. This research was also focused on evaluating the fluorescent probe, oligomeric p-phenylene ethynylene (OPE), as an amyloid …

Eutherian Biogeography During The Puercan North American Land Mammal Age (Paleocene, Earliest Danian): Problems And Potential Solutions, Jason Sterling Silviria

Earth and Planetary Sciences ETDs

The Puercan North American Land Mammal Age (NALMA) is the earliest major North American terrestrial biochron of the Cenozoic era, spanning roughly the first one million years of the Paleogene period (Paleocene epoch, Danian stage; ~66.04-65.12 Ma). It is typified by the explosive ecomorphological diversification of the mammalian clade Eutheria (particularly our subclade, Placentalia), following the annihilation of non-avian dinosaurs and “archaic” mammal groups during the Cretaceous/Paleogene (K-Pg) mass extinction event. The spatiotemporal mode and tempo of Puercan eutherian diversification has long been the subject of debate, with disagreements over biogeographic zonation. The traditional model – based largely on well-sampled, …

“We Practice Lakota Way, But We Are Not An Indian Church”: The Diverse Ways Lakota Christians Articulate, Perform And Translate Ethnicity In Congregational Life, Kristin A. Fitzgerald

Anthropology ETDs

This study looks at articulations, performances and translations of ethnicity among urban Lakota Christians at St. Matthew’s and St. Isaac Jogues in Rapid City, South Dakota. Within the context of increased ethnic revitalization and recognition, Native American Christians are negotiating new models of ethnicity in typically Western arenas, often manifesting through actions and discourse that are ostensibly traditional. Yet even in this era of recognition, the public performance of cultural authenticity is not the only thing on people’s minds. Native people mark various practices, symbols, and persons as traditional or modern at different points in history or within different contexts …

From Deconstruction To Rehabilitation: Heidegger, Gadamer, And Modernity, David Liakos

Philosophy ETDs

This dissertation is a study of the problem of modernity, formulated as the following multivalent question: How should we understand the scope, character, and limitations of our historical age? The study approaches this question from the point of view of Martin Heidegger and Hans-Georg Gadamer. We will, first, clarify how Heidegger and Gadamer think about modernity, thereby shedding light on their widely misunderstood intellectual relationship; and, next, uncover and defend a distinctively Gadamerian response to modernity as a viable argument, and as potentially more coherent and hopeful than Heidegger’s answer to the problem of the modern age.

In the first …

Medieval Narratives As Meta-Constructions Used In Creating Socio-Cultural Identity, Laurie A. Price

Linguistics ETDs

This study of the distribution and function of Historical Present (HP) in Old French, Old English, and Old Norse narratives combines the methods of cognitive linguistics and corpus-based discourse analysis with insights from work in sociolinguistics, linguistic anthropology and medieval studies. I show that HP, in combination with those other features, is a strategy to establish stance, a strategy that both constructs and reinforces a cultural persona. Although previous research on HP in narratives focused on the use of HP to foreground events and contrast marked vs unmarked events in narratives, my analysis shows that HP has an additional range …

Interdependencies Between Energy, The Environment, And Stakeholder Choices, Saleh Nur Muhammad Al Mamun

Economics ETDs

This dissertation contributes to the field of energy economics by expanding the knowledge of energy stakeholders’ decisions amid the interdependence of energy and environmental policies. I analyze three specific energy development decisions from multiple stakeholders’ perspectives. Chapter 2 introduces a broader state-level policymakers’ decision on renewable portfolio standards (RPS). The renewable portfolio standards is a state-mandated obligation that requires electric load-serving entities to distribute a certain percentage of electricity generated from renewable sources. I investigate the public preferences of RPS for residents in New Mexico in 2017. I find that households are willing to pay for an increase in RPS …

The Impact Of Exogenous Shocks And Heterogeneity On Demand And Preferences Environmental And Resource Goods In The Southwestern United States, Kara A. Walter

Economics ETDs

The 2018 IPCC report declared damages from climate change rapidly approaching. This dissertation consists of three empirical studies employing unique data sets and three econometric methods. First, I consider energy portfolios; I find that political affiliation is not the strongest driving factor of heterogeneity. Second, I examine the impact of observable characteristics in explaining preferences for the environment and regulation; I find opinion on climate change is an important factor and that omitting it results in changes to the significance of other factors. Finally, I study the impact of wildfires on visitation to national parks; I find that in the …

Practical Modelling Of The Vanilla Option Volatility Smile, Jacob E. Shanley

Mathematics & Statistics ETDs

Many discussions on how best to model the standard American Option derivative focus solely upon the volatility smile modelling itself from a mathematical perspective. This thesis instead closely examines both the practical and mathematical implications of processing market data, modelling the volatility smile, and making real-world trading decisions from the results. In particular, it contains an analysis of market data processing algorithms, new volatility smile models, multiple empirically-driven weighting schemes, Gauss-Newton and Levenberg-Marquardt optimization algorithms, and various trading strategies. The top performing combinations found were those that involved the Smile and Twist volatility smile models, Volatility Width Vega Multiplier weighting …

Single Crystal Elasticity Of Hydrous Fe-Bearing Wadsleyite At High-Pressure Condition, Zhiyuan Ren

Earth and Planetary Sciences ETDs

The 410-discontinuity separating the uppermost mantle from the transition zone is commonly believed to be caused by the olivine-wadsleyite transformation. However, the velocity change at the 410-discontinuity predicted by the standard pyrolitic model is not completely consistent with the seismic observations, leading to questions about the accuracy of the seismic models, or uncertainties of the mineral physics predictions. More regional seismic observations suggest that the depth, sharpness, and velocity jumps at the 410-discontinuity are different at different places, caused by thermal and/or compositional heterogeneities in the upper mantle. To explain the inconsistencies between the mineral physics and seismic models and …

Evaluating Sources Of Hydrochemical Variability And Mixing In The Upper Gila River, New Mexico, Pavel Vakhlamov

Earth and Planetary Sciences ETDs

This study of the upper reaches of the Gila River basin in southwestern New Mexico reveals both spatial and seasonal patterns in physical and hydrochemical parameters. Monsoonal precipitation, temporal variability in water chemistry of streams in the upper Gila watershed is significantly impacted by surface runoff due to variability in landscape cover features, as well as surface area of the catchment. However, during base flow regimes spring inputs are the dominant drivers of solute concentrations and chemical variability.

Geothermal sources play a major role in salinization of the southwestern stream systems. Prolonged water/rock interaction combined with high temperature, pressure result …

A Hybrid Gis/In Situ Analysis Of Aed Coverage On The Unm Central Campus, Ian T. Hill

Geography ETDs

Automated External Defibrillators (AED’s) are lifesaving devices that can greatly improve the survival rates of cardiac arrest when used quickly. There are publicly accessible AED’s on the UNM campus, and each device has an effective range based on how quickly a responder can retrieve the AED and return it to the site of the cardiac emergency. The ranges of the AED’s on UNM central campus are analyzed using GIS, interior building measurements, and various retrieval speeds. This helps evaluate the current placement of AED’s on campus and helps reveal where future coverage is needed. This focus on the combined navigation …

Communicative And Collective Formative Program Evaluation: A Descriptive Case Study Of Experiences Of Teachers And Students In Saudi Arabia, Ahmed Khawaji

Language, Literacy, and Sociocultural Studies ETDs

Saudi students who matriculate in programs of higher education in Saudi Arabia confront major language obstacles that hinder their academic output, due to the transition from high school, which employs Arabic-language instruction, to the English-medium of instruction in post-high school education. Preparatory Year Programs (PYPs) established to aid students’ transition, from Arabic to English, have not produced satisfactory results (Alseweed & Daif-Allah, 2013). Those programs have rarely been submitted to any form of formative evaluation procedures (Barnawi, 2011).

This descriptive case study embarked on evaluating formatively the English Language Teaching (ELT) in a Saudi university through bridging the perspectives or …

A Qualitative Examination Of Prostate Cancer Treatment Decision-Making Among Black Men, Linda Ottley

Nursing ETDs

This ethnographic study explored the experience of treatment decision-making among urban Black men who were diagnosed with prostate cancer in San Diego, California. Specifically, this research was conducted to further understand the decision-making process among Black men and the barriers they face when making treatment decisions about prostate cancer. The study is important because prostate cancer disproportionately affects Black men in the United States, and yet they are underrepresented in research studies (Randolph, Coakley, & Shears, 2018). These inequities are poorly understood and need considerable analysis and exploration. Still unclear is the possible effect of historical trauma or negative healthcare …

The Production Cross Section Of The J/Ψ Meson Measured Using The Phenix Detector At √ S =510 Gev, Katherine Marie Deblasio

Physics & Astronomy ETDs

The inclusive differential production cross section of the J/ψ meson is measured with the PHENIX detector for p + p collisions at √ s = 510 GeV using the 2013 RHIC dataset. The measurement is performed using the dimuon decay channel at forward and backward rapidity ranges of 1.2 < |y| < 2.2 and for transverse momenta up to 12 GeV/c. The experimental results are compared to current predictions in NRQCD and serves to shed light on the ambiguity of the J/ψ production mechanism. The 2013 RHIC dataset provides unique challenges to the cross section measurement due to the effects of detector pile-up from multiple collisions. Techniques to quantify these effects are discussed.

Measurement And Control For Quantum State Tomography, State Preparation, And Metrology, Ezad Shojaee Mr.

Physics & Astronomy ETDs

Quantum information science can deliver its promises in technology if we have access to near-perfect quantum states, quantum channels, and readout. These are the building blocks of any quantum informatics in computation, communication, and simulation. Invasiveness of quantum measurement is one of the major challenges in this realm. The fact that after a measurement the quantum state changes is now a rule of the game. We need smart ways to gain information about a quantum state, given finite resources, in order to characterize it prior to any task.

In this dissertation, we realize the optimal way to do quantum state …

Plasmon-enhanced photochemistry of p-aminothiophenol as a model molecule is investigated using highly sensitive surface-enhanced Raman spectroscopy (SERS). The …

Pixelated Gasb Membranes For Photovoltaics: Fabrication And Structure-Property Relationships, Vijay Saradhi Mangu

Electrical and Computer Engineering ETDs

In this thesis, I present a reliable and efficient approach to heterogeneous integration of single-crystalline GaSb semiconductors with highly mismatched materials. The mismatch may refer to the crystalline structure and the thermal expansion coefficient of single-crystalline GaSb and the other materials of interest. The strategy of hetero-integration relies on epitaxial lift-off. This approach prevents the formation of extended structural defects that are detrimental to the performance of optoelectronic devices and preserves GaSb growth substrates for potential reuse.

Within my research work, I have overcome some outstanding challenges of epitaxial lift-off of GaSb, and I have demonstrated the operation of single-crystalline …

Reducing Threading Dislocation In Gasb Epilayer Grown On Gaas Substrate For Photovoltaic And Thermophotovoltaic Application, Ahmad Mansoori

Optical Science and Engineering ETDs

GaSb based photovoltaic devices have been demonstrated on GaAs substrates by an inducing interfacial array of 90° misfit dislocations. Despite the beneficial qualities of the highly stable 90° misfit dislocation, there is a significant density of residual threading dislocations in the GaSb layer, resulting in the degradation of the electrical performance of such photovoltaic cells compared to lattice matched devices. We aim to reduce threading dislocation density by optimizing growth temperature and by using an AlSb dislocation filtering layer. The growth temperature optimization results in a reduction of the threading dislocation density to 1.3 × 10⁸ cm⁻². …

Female Protagonist Mega-Archetypes: A Study In Medieval European Romances, Doaa Omran

English Language and Literature ETDs

Despite the claim that structuralism has sung its swan song, my research offers new insights in the field of structuralism through archetypal criticism by exploring four female hero mega-archetypes as narrative structures inspired by the Qur’an and the Bible. These scriptural narratives offer tenets, based on narratives and motifs, that, as structural units, create and identify mega-archetypes. This study posits how, rather than being extensions of existing structuralist taxonomies on the male hero monomyth, the female mega-archetypes enrich that monomythical narrative. This work details the structure of the mega-archetypes Zulaikhah (Potiphar’s wife), Sarah and Hagar, the Virgin Mary, and Queen …
