Methods: This was a descriptive retrospective chart review study that analysed the incidence of COVID-19, incidental detection of laboratory-confirmed COVID-19 …

Inclusive And Anti-Racist Collecting At Unlv: Draft Report And Recommendations, Annette Day, Sarah R. Jones, Amy Tureen, Susan B. Wainscott, Amanda Melilli, Thomas Padilla, Aidy Weeks

Library Faculty Research

The UNLV University Libraries recognizes that as both a direct and indirect result of colonialism and white supremacy the historical and contemporary scholarly publishing market atypically centers and prioritizes voices that are white, male, Christian, able-bodied, and heterosexual (Muka, 2018; Ray, 2018; Baffoe, Asimeng-Boahene, & Buster, 2014; and Buggs, Sims, & Kramer, 2020). In an attempt to redress this imbalance, the UNLV University Libraries is committed to collecting content by and about people and communities that have historically been excluded. This effort includes but is not limited to the intentional collection of materials about and by groups historically excluded by …

Diverse Stem Cells For Periodontal Tissue Formation And Regeneration, Mizuki Nagata, Jeryl D English, Noriaki Ono, Wanida Ono

Faculty, Staff and Student Publications

The periodontium is comprised of multiple units of mineralized and nonmineralized tissues including the cementum on the root surface, the alveolar bone, periodontal ligament (PDL), and the gingiva. PDL contains a variety of cell populations including mesenchymal stem/progenitor cells (MSCs) termed PDLSCs, which contribute to periodontal regeneration. Recent studies utilizing mouse genetic models shed light on the identities of these mesenchymal progenitors in their native environment, particularly regarding how they contribute to homeostasis and repair of the periodontium. The current concept is that mesenchymal progenitors in the PDL are localized to the perivascular niche. Single-cell RNA sequencing (scRNA-seq) analyses reveal …

An Inexpensive Maximum Power Point Tracking System For An Insulated Solar Electric Cooker Using An Off-The-Shelf Buck Converter, Andrew A. Perez

Physics

A specialized control circuit using an off-the-shelf buck converter is built for an Insulated Solar Electric Cooker (ISEC). Cost and efficient power delivery are the focus. An ISEC is synonymous to a direct load heat resistor, allowing a specific maximum power point tracking (MPPT) algorithm and fewer components. Only a microcontroller, voltage sensor, and digital-to-analog converter are used with the buck converter to maximize the power delivered by a 100W solar panel for the 3.3Ω load.

Can Affordable Homes Be Healthy? Legal Strategy, Socio-Legal Studies And Activism In Indonesia, Santy Kouwagam

The Indonesian Journal of Socio-Legal Studies

This article uses two Constitutional Court decisions in Indonesia to exemplify the importance of analysing legal strategies. These decisions declared a rule barring developers from building and selling tiny houses to be unconstitutional and invalid. The article shows that ‘justice’ in legal procedures still needs further definition, and that judges’ elaboration of decisions and their legal reasoning still needs improvement. The article will first discuss the cases, using Legal Strategy analysis. It will then highlight problems with the commoditisation of houses. Finally, it will argue that the problem of unhealthy and unaffordable housing in Indonesia can be resolved, by bringing …

Modeling Electrokinetic Flows With The Discrete Ion Stochastic Continuum Overdamped Solvent Algorithm, D. R. Ladiges, J. G. Wang, I. Srivastava, A. Nonaka, J. B. Bell, S. P. Carney, A. L. Garcia, A. Donev

Faculty Research, Scholarly, and Creative Activity

In this article we develop an algorithm for the efficient simulation of electrolytes in the presence of physical boundaries. In previous work the discrete ion stochastic continuum overdamped solvent (DISCOS) algorithm was derived for triply periodic domains, and was validated through ion-ion pair correlation functions and Debye-Hückel-Onsager theory for conductivity, including the Wien effect for strong electric fields. In extending this approach to include an accurate treatment of physical boundaries we must address several important issues. First, the modifications to the spreading and interpolation operators necessary to incorporate interactions of the ions with the boundary are described. Next we discuss …

Understanding The Role Of Transportation In Combating Human Trafficking In California, Kezban Yagci Sokat

Faculty Research, Scholarly, and Creative Activity

Human trafficking, a form of modern slavery, is the recruitment, transport, transfer of persons using force, fraud or coercion to exploit them for act of labor or sex. According to the International Labor Organization, human trafficking is the fastest growing organized crime with approximately $150 billion in annual profits and 40.3 million individuals trapped in slave-like conditions. While it is not compulsory to involve transportation for human trafficking, the transportation industry plays a critical role in combating human trafficking as traffickers often rely the transportation system to recruit, move or transfer victims of human trafficking for either sex or forced …

Multichannel Blind Deconvolution Of Circularly Polarized Imagery, Patrick B. Cunningham

Theses and Dissertations

Current methods can be used to recreate an expected Stokes polarization vector from measured light for characterization purposes. However, this only applies to three of the Stokes parameters, that is, the linear polarization components. Circular polarization is not currently being utilized for object characterization because the mathematical complexity is greater than for that of linear polarization. This research will analyze a way to expand existing algorithms to include circular polarization and enable the complete reconstruction of the Stokes vector from the measured light into a blind deconvolution algorithm for Stokes estimation and image reconstruction.

Additive Manufacturing Of Molybdenum For High Temperature Structural Applications, Megan L. Bustin

Theses and Dissertations

This research considered additive manufactured (AM) molybdenum (Mo) and the effect of three variables on microstructure, mechanical properties, and the relationship between the two. Test temperature, laser speed, and shield gas or build atmosphere were varied, and samples tested and analyzed using a three-point bending test, chemical composition, and optical and scanning electron microscopy. The relationship among variables and results using a Design of Experiments was limited compared to the inclusion of every tested sample. Most effects were expected: samples tested at room temperature were brittle without statistical significance; increasing laser speed resulted in decreased ductility and strain, smaller grain …

Development Of A Security-Focused Multi-Channel Communication Protocol And Associated Quality Of Secure Service (Qoss) Metrics, Paul M. Simon

Theses and Dissertations

The threat of eavesdropping, and the challenge of recognizing and correcting for corrupted or suppressed information in communication systems is a consistent challenge. Effectively managing protection mechanisms requires an ability to accurately gauge the likelihood or severity of a threat, and adapt the security features available in a system to mitigate the threat. This research focuses on the design and development of a security-focused communication protocol at the session-layer based on a re-prioritized communication architecture model and associated metrics. From a probabilistic model that considers data leakage and data corruption as surrogates for breaches of confidentiality and integrity, a set …

Analysis Of Graph Layout Algorithms For Use In Command And Control Network Graphs, Matthew R. Stone

Theses and Dissertations

This research is intended to determine which styles of layout algorithm are well suited to Command and Control (C2) network graphs to replace current manual layout methods. Manual methods are time intensive and an automated layout algorithm should decrease the time spent creating network graphs. Simulations on realistic synthetically generated graphs provide information to help infer which algorithms perform better than others on this problem. Data is generated using statistics drawn from multiple real world C2 network graphs. The three algorithms tested against this data are the Spectral algorithm, the Dot algorithm, and the Fruchterman-Reingold algorithm. The results include a …

Efficiency Quantification For Pulsed-Source Digital Holographic Wavefront Sensing, Steven A. Owens

Theses and Dissertations

The efficiencies of a digital holography (DH) system in the pulsed configuration and the off-axis image plane recording geometry are analyzed. First, the system efficiencies of an infrared-wavelength DH system in a homodyne-pulsed configuration are measured and compared to those of a visible-wavelength DH system in a homodyne-continuous-wave (CW) configuration. The total-system, excess-reference-noise, shot-noise-limit, and mixing efficiencies of the pulsed-source system were found to be consistent with those of the CW-source system. This indicated no new efficiencies were necessary to characterize pulsed-source systems when no temporal delay exists between the pulses. The consistency of efficiencies also showed infrared DH systems …

Root-Cause Analysis Of Rsaf Maintenance-Related Flight Safety Mishaps, Heaf H. Alqahtani

Theses and Dissertations

Poor maintenance is a major factor in many aviation mishaps. This is due to the fact that some maintenance activities are carried out improperly or overlooked as a result of human error. It is important to acknowledge that maintenance mistakes are a visible sign of deeper organizational issues. Therefore, adequate solutions to maintenance issues must consider organizational influences. Despite efforts to reduce the accident rate within the Royal Saudi Air Force (RSAF), the RSAF suffers from an increasing trend in mishaps attributed to maintenance. Therefore, safety data was analyzed to examine trends. Additionally, the Human Factors Analysis and Classification System …

A Case Study Of The Efficacy Of Model-Based Requests For Information, Kyle J. Arruda

Theses and Dissertations

The Department of Defense (DoD) has encouraged the transition to digital engineering, yet there are limited guides for how to transition and there is limited data to show where an organization like a program office can reap the most benefit from the transition. To identify areas where potential benefits may be realized, this thesis compares two Requests for Information (RFIs), one document-based and one model-based, from generation to response. A survey was developed and administered to 7 members of a single program office to grade the RFI responses. The survey was based on the 43 benefit categories identified in the …

Generative Methods, Meta-Learning, And Meta-Heuristics For Robust Cyber Defense, Marc W. Chalé

Theses and Dissertations

Cyberspace is the digital communications network that supports the internet of battlefield things (IoBT), the model by which defense-centric sensors, computers, actuators and humans are digitally connected. A secure IoBT infrastructure facilitates real time implementation of the observe, orient, decide, act (OODA) loop across distributed subsystems. Successful hacking efforts by cyber criminals and strategic adversaries suggest that cyber systems such as the IoBT are not secure. Three lines of effort demonstrate a path towards a more robust IoBT. First, a baseline data set of enterprise cyber network traffic was collected and modelled with generative methods allowing the generation of realistic, …

A Practical Tool To Enhance Faculty And Student Interactions Surrounding E-Learning Platforms, Kimberly N. Williams, Alexandria K. Gombas, Claudia Cornejo Happel, Tracy C. Parodi, Elizabeth H. Lazzara, Barbara Chaparro

Publications

Learning management systems (LMS) are prevalent in modern day education, but their implementation is often highly diverse based on individual faculty and course needs. This can result in students falling behind in their schoolwork if they do not understand how faculty use the e-learning platform in specific courses, which may be further exacerbated when students are exposed to many different faculty using learning management systems in different ways at a single institution. The current research sought to create a practical tool to reduce the impact of diverse LMS implementation through the generation of a homepage template that could be customized …

Local Norms And Gifted/Talented Identification In Arkansas, Sarah C. Mckenzie, Josh B. Mcgee, Bich Tran, Kathryn Barnes, Charlene A. Reid

Policy Briefs

In this brief, we summarize recent research from OEP examining if using school- or district-level norms from state assessments would increase the racial and programmatic diversity of Arkansas students identified as Gifted and Talented (G/T). Using ten years of administrative data to analyze the outcomes of a local norms approach compared to the current G/T identification strategies, we find no consistent evidence that using a local norms approach for G/T identification would improve racial or programmatic diversity.
