The Impact Of Synchronous And Asynchronous Preference On The Performance Of Distance Learning Students, Christopher A. Wilson

Electronic Theses and Dissertations

Distance learning is a growing part of education. The transition to distance learning was underway at higher education institutions, but the COVID-19 pandemic forced institutions of all types to rapidly transition to distance learning. The technology that was adapted during this emergency distance learning remained in the classroom once normal instruction resumed. This quantitative study examined two aspects of distance learning technology in education. The study examined student preference for either synchronous or asynchronous instruction through the framework of expectancy theory. Students who were more familiar with the course material were hypothesized to have a higher expectation of success and …

Strong Q-Analogues For Values Of The Dirichlet Beta Function, Ankush Goswami, Tim Huber

School of Mathematical & Statistical Sciences Faculty Publications

An infinite class of relations between modular forms is constructed that generalizes evaluations of the Dirichlet beta function at odd positive integers. The work is motivated by a base case appearing in Ramanujan’s Notebooks and a parallel construction for the Riemann zeta function. The identities are shown to be strong q-analogues by virtue of their reduction to the classical beta evaluations as 𝑞→1− and explicit evaluations at CM points for |𝑞|< 1. We also determine asymptotic formulas for the Fourier coefficients of the associated modular forms.

Optimal Quantization On Spherical Surfaces: Continuous And Discrete Models—A Beginner-Friendly Expository Study, Mrinal Kanti Roychowdhury

School of Mathematical & Statistical Sciences Faculty Publications

This expository paper provides a unified and pedagogical introduction to optimal quantization for probability measures supported on spherical curves and discrete subsets ofthe sphere, emphasizing both continuous and discrete settings. We first present a detailedgeometric and analytical foundation for intrinsic quantization on the unit sphere, includingdefinitions of great and small circles, spherical triangles, geodesic distance, Slerp interpolation,the Fréchet mean, spherical Voronoi regions, centroid conditions, and quantizationdimensions. Building upon this framework, we develop explicit continuous and discretequantization models on spherical curves, namely great circles, small circles, and greatcircular arcs—supported by rigorous derivations and pedagogical exposition. For uniformcontinuous distributions, we compute optimal …

Sapphire Optical Fiber Bragg Grating Sensors Based On Dispersive Microwave-Photonic Frequency-Time Domain Analysis, Ruimin Jie, Chen Zhu, Farhan Mumtaz, Koustav Dey, Bohong Zhang, Jie Huang

Electrical and Computer Engineering Faculty Research & Creative Works

Sapphire fiber Bragg gratings (SFBGs) have attracted growing interest for high temperature sensing in harsh environments, yet their interrogation typically relies on optical spectrum measurements, demanding a high-resolution optical spectrum analyzer (OSA) that is bulky, expensive, and constrained in acquisition speed. Moreover, the inherently multimode nature of sapphire fiber further complicates spectrum-based demodulation, thereby limiting the achievable sensing resolution. In this paper, we propose and experimentally demonstrate a microwave-photonic interrogation approach for SFBG sensors. Instead of measuring the optical reflection spectrum, the complex frequency response in the microwave domain of an SFBG is acquired using a vector network analyzer (VNA) …

Lidar-Based Framework For Detecting Suspicious Human Activities, Ahd Aljumah, Charalampos Antoniadis, Hakim Ghazzai, Nawfal Guefrachi, Ahmad Alsharoa, Gianluca Setti

Electrical and Computer Engineering Faculty Research & Creative Works

This study explores the development of Human Activity Recognition (HAR) systems capable of identifying suspicious activities to enhance security in public spaces. We propose an innovative solution that integrates LiDAR sensors with deep learning technologies. Our method employs advanced models operating on LiDAR point cloud, PV-RCNN for human detection, and LidarGait++ for classifying activities into categories such as standing or walking (non-suspicious) and sneaking or fighting (suspicious). Due to the scarcity of suitable real-world datasets for training such systems, we utilize a 3D simulation tool, Blender, to create realistic environments and generate labeled point cloud data. This synthetic dataset allows …

Deep Learning Approach For Microwave Imaging Based On Deep Convolutional Asymmetric Encoder-Decoder Structure And Physics-Induced Loss, He Ming Yao, Shiji Song, Michael Kwok Po Ng, Lijun Jiang

Electrical and Computer Engineering Faculty Research & Creative Works

In this paper, we introduce an innovative deep learning (DL) methodology designed for real-time quantitative microwave imaging (MWI). Our approach is centered around the utilization of a deep convolutional asymmetric encoder-decoder structure (DCAEDS), which requires only a single-frequency far-field measurement of the electromagnetic (EM) scattered field as input and subsequently predicts the contrasts (permittivities) of the target materials. During the offline training process, we incorporate an EM forward solver specifically crafted to compute the EM scattered field generated by the predicted target contrasts (permittivities) produced by the DCAEDS. The DCAEDS is seamlessly integrated with this EM forward solver to optimize …

Gauge-Invariant Gravitational Wave Polarization In Metric F(R) Gravity With Cosmological Implications, Ramesh Radhakrishnan, David Mcnutt, Delaram Mirfendereski, Alejandro Pinero, Eric Davis, William Julius, Gerald Cleaver

Physics & Astronomy Faculty Publications

We develop a fully gauge-invariant analysis of gravitational-wave polarizations in metric 𝑓⁡(𝑅) gravity with a particular focus on the modified Starobinsky model 𝑓⁡(𝑅) =𝑅 +𝛼⁢𝑅2 −2⁢Λ, whose constant-curvature solution 𝑅𝑑 =4⁢Λ provides a natural de Sitter background for both early- and late-time cosmology. Linearizing the field equations around this background, we derive the Klein–Gordon equation for the curvature perturbation 𝛿⁢𝑅 and show that the scalar propagating mode acquires a mass 𝑚2𝜓 =1/(6⁢𝛼), highlighting how the same scalar degree of freedom governs inflationary dynamics at high curvature and the propagation of gravitational waves in the current accelerating Universe. Using the scalar–vector–tensor …

Gpu And Pso Accelerated Low-Latency Fully-Coherent All-Sky Search For Compact Binary Coalescences, Soumya D. Mohanty

Physics & Astronomy Faculty Publications

The fully-coherent all-sky (FCAS) search, which combines data from a gravitational wave detector network into a single likelihood function, is the preferred method prescribed by statistical theory for Gaussian noise. However, so far, its exorbitant computational cost has blocked its use for compact binary coalescence searches. We introduce a solution combining Particle Swarm Optimization with Graphics Processing Unit (GPU) acceleration that is ≈ 50-fold faster than real-time analysis. This transforms the prospect of a low-latency FCAS search on all GW data into a practical reality for the first time. With large-scale simulations enabled by this speedup, we examine the issue …

Efficient Search For Detection Candidates Using A Peak Finder Strategy For All-Sky-All-Frequency Gravitational Wave Radiometer, Arindam Sharma, Deepali Agarwal, Sanjit Mitra

Physics & Astronomy Faculty Publications

The first all-sky-all-frequency (ASAF) radiometer search was conducted using data from the first three observing runs of the Advanced LIGO and Advanced Virgo detectors. The significance of this search lies in its fast and unmodeled approach, leveraging a cross-correlation technique to identify common signals across the detector network. As a result, this method serves as an excellent alternative to search for unknown or poorly modeled continuous wave sources and narrow band components of the gravitational wave (GW) background. For continuous wave sources whose waveform can be modeled, this method can serve as the first stage of a hierarchical scheme by …

Pediatric Both Bone Fracture Leading To Median Nerve Entrapment: A Case Report, Joshua Lyndon Dale, Frank Gerold

Case report: We present the case of a 13-year-old male who sustained a both-bone forearm fracture while on vacation in Mexico. The injury was managed with closed reduction and casting. Despite appropriate treatment, the patient developed progressive numbness, tingling, and thenar atrophy in the median nerve distribution. Electromyography and nerve conduction studies confirmed significant median nerve dysfunction. Surgical exploration revealed the median nerve entrapped in …

Drone Dichotomy: Investigating The Application Of Unmanned Aerial Systems For Offensive And Defensive Chemical, Biological, Radiological, And Nuclear-Related Tasks, Evan Jacob Martinovitch

Graduate Theses/Dissertations

This thesis investigates the application of unmanned aerial systems (UAS) for both offensive and defensive chemical, biological, radiological, and nuclear (CBRN) tasks to determine if they serve as a force multiplier on the modern battlefield. As CBRN weapons reemerge as realistic threats alongside the rapid proliferation of UAS, the intersection of these fields presents unique challenges and opportunities. Through a methodology that examines the history of the UAS-CBRN intersection, military doctrine, and the status of UAS technology, this research evaluates the capability of current and emerging UAS against specific CBRN delivery, reconnaissance and surveillance, and decontamination tasks. The analysis conducted …

Northern Luzon In A Taiwan Flashpoint: The Philippines’ Place In U.S. Strategy, Carson Keller

Graduate Theses/Dissertations

While the defense of Taiwan from a potential invasion by the People’s Republic of China (PRC) has long been a topic of debate and scrutiny in U.S. strategic thinking, the role of its southern neighbor, the Philippines, has received far less attention. This thesis argues that northern Luzon would constitute key terrain in a cross-strait conflict and may become an early target of People’s Liberation Army (PLA) operations. Its proximity to Taiwan and position along the Luzon Strait, particularly the Bashi Channel, places it at the center of efforts to control access to the hypothetical battlespace. Drawing on PLA and …

Spatial Patterns And Morphometric Evolution Of Sinkholes In Response To Watershed Hydrogeomorphology: Examples From A Karst Landscape In The Missouri Ozarks, Usa, Marcell Tóth

Graduate Theses/Dissertations

Sinkholes are characteristic enclosed depressions with internal drainage connecting the surface and subsurface karst hydrologic system. Their morphological evolution involves gradual subsidence of the ground surface and hazardous collapses. Therefore, understanding sinkhole morphometry and linked spatial distribution is critical for managing geohazards in karst watersheds. Sinkhole occurrence shows spatial variability based on watershed geomorphological attributes, surficial hydrological patterns, hydrogeological and geological settings. The aim of this research is to investigate morphometric properties and distribution of sinkholes in the carbonate karst-dominated lands of Mark Twain National Forest in Missouri, USA. The specific objectives were to (1) identify sinkhole clusters based on …

Confucian Thought As A Strategic Veil: How Western Strategy Should Correctly Compete With China, Owen Miller

Graduate Theses/Dissertations

The rise of the People's Republic of China as a peer competitor to the United States constitutes the defining geopolitical challenge of the twenty-first century, but even so, Western strategic analysis has consistently failed to engage China on its own terms. The recurrent pattern of Western misinterpretation results from projecting Western assumptions onto a state whose institutional and cultural drivers operate under fundamentally different premises, where key elements of Chinese strategic culture and the Chinese Communist Party’s (CCP) instrumentalization of Confucianism as a moral veil are instruments of domestic legitimacy and external strategic narrative. The United States must recognize that …

31p Solution Nmr Investigation Of Abasic Dna, Clarissa R. Krimmel

Graduate Theses/Dissertations

Base excision repair (BER) mechanisms fix single base lesions in DNA, such as T:G mismatches. During the base excision repair mechanism, an abasic site (AP site) is formed as an intermediate. AP sites are unstable and highly mutagenic; they can stop DNA replication. This research investigates how the conformational properties of abasic sites in DNA affect the binding recognition of enzymes involved in DNA repair mechanisms, including BER. Three different abasic sequences are being analyzed for this research project. A second project looks at the effects of a naturally occurring purine derivative, hypoxanthine, on the DNA backbone. These hypoxanthine lesions …

Strict Scrutiny And The Viewpoint Continuum, A.G. Harmon

Scholarly Articles

Consider the following instances: A cell phone photograph picturing a man's left kneecap. A statement that the speaker thinks, "The name Josiah is really cool." A woman who runs her bicycle over a business owner in order to gain celebrity and increase attention for her new podcast. An intentional lie told to acquire a job. A student who insists on answering his math exam questions in runic symbols.

At one point or another, American courts have considered the merits found in favor of instances similar to these and other like circumstances as amounting to "viewpoints." As such, they …

The Constitutional Significance Of The First American Pope: The Promise Of Listening In An Era Of Mutual Suspicion, Derek A. Webb

Scholarly Articles

Pope Leo XIV has focused a good deal of writing and speaking in the first year of his pontificate on the theme of listening, dialogue, and bridgebuilding. For Leo, listening, dialogue, and creating harmony across diverse perspectives where possible are at the heart of the Christian life. But his reflections on these themes, while rooted in theology, are aimed at a wider audience, going well beyond the church community, and addressing philosophical issues of universal human concern. Indeed, the first American pope happens to be highlighting certain ideals regarding dialogue that, while perhaps forgotten today, are central to the American …

Bennett, Jill A. Poole, Keshoer R. Bidasee, Geoffrey M. Thiele, Ted R. Mikuls

Journal Articles: Cellular & Integrative Physiology

Individuals with rheumatoid arthritis (RA) experience increased risk of heart failure. Malondialdehyde-acetaldehyde (MAA) adducts are overexpressed and co-localize with citrullinated (CIT) proteins in RA myocardium. This study investigated whether reactive aldehyde species (RASP) inhibitors prevent MAA formation in vitro and attenuate cardiac dysfunction in a collagen-induced arthritis (CIA) mouse model. Among eight RASP inhibitors screened, ADX-246 demonstrated the greatest inhibition of MAA formation in vitro. Mice with early CIA (week 5) exhibited elevated levels of myocardial MAA adducts, myocardial inflammation, and reduced ejection fraction, but normal cardiac collagen deposition and diastolic function vs. control. By weeks 10-12, mice with chronic …

A User-Friendly Graphical User Interface For Paw Touch Classification In Rodent Cylinder Testing, Tyler R Johnson, Katherine D Zerefos, Dawn M Taylor

Faculty, Staff and Student Publications

In unilateral rodent models of disease or injury, deficits are induced in only one side of the body, allowing the difference in right versus left limb usage to serve as a metric of disease/injury severity and recovery with various treatments. Unilateral rat models are commonly used for conditions such as Parkinson’s disease (via the neurotoxin 6-hydroxydopamine, 6-OHDA), stroke, and traumatic brain injury, as well as cervical spinal cord injury and peripheral nerve damage. The ‘cylinder test’ has been used for over two decades as a reliable metric of asymmetry in forelimb usage. In this test, videos are taken of the …

I, Cock-A-Doodle-Do: Reclaiming Masculinity Through Queer Joy And Humorous Self-Exploration, Nelson J. Garcia

Graduate Studies Theses and Dissertations 2026

I examine the contemporary norms of masculinity. My research wrestles with ultimately unresolvable stereotypes and imagery influencing current masculine behavior. I unearth queer potential through the physicality and behavior of the stereotypical “man’s man”. I infuse my own queer identity into my studio practice with an emphasis on humor and joy to subvert traditional models of male performance. This process drives self-exploration that allows me to personally respond, react, be directed, and redirected by the interactions between queerness and masculinity. Masculine and queer representations across various media, such as film, music, and television, historically and continuously inform restrictive cultural norms. …

Relating To Difficult Weather Through Creative Practice: Responses To Marrugeku’S Cut The Sky, Helena Grehan, Jo Pollitt, O. J.E. Slater, Sam Fox

Research outputs 2022 to 2026

In this paper we argue that performance and the arts invite a deliberate sensorial connection with the body and can support a bodily turn or return, in order to help artists, scholars and communities more broadly, better attune to increasing climate instability, through collaborative, supportive and reflexive storytelling. Drawing on the three “weather” symposia, the paper focusses on the second symposium which featured a keynote presentation by Rachael Swain, co-artistic director of Marrugeku, Australia’s leading Indigenous Intercultural Dance and Performance Company. Responses to Marrugeku’s work Cut the Sky are collectively presented to illuminate what Swain argues are, “Dramaturgies of consequence” …
