Cogram: A Computational Pipeline For Genome Assembly And Reconstruction Using Graph Neural Networks, William Coggins

College of Graduate Studies: Theses & Dissertations

Genome assembly — the reconstruction of a complete DNA sequence from short, overlapping reads — remains a fundamental challenge in computational biology. A central difficulty is distinguishing true genomic overlaps from spurious connections arising from repetitive sequences, a task that traditional assemblers address through hand-tuned heuristic rules applied to de Bruijn or overlap graphs. This thesis introduces COGRAM (Coggins–Ramasamy Assembly Method), a genome assembly pipeline that reframes sequence reconstruction as an edge classification task on a k-mer overlap graph, replacing heuristic graph cleaning with a learned model.

COGRAM constructs a directed overlap graph from raw sequencing reads using a k-mer …

Pile Setup Effects On Driven Piles In Southeastern Coastal States, Peya Sharif

College of Graduate Studies: Theses & Dissertations

The resistance of driven piles typically increases with time after installation, a phenomenon known as pile setup. This behavior is primarily associated with the dissipation of excess porewater pressure and the progressive reconsolidation of soil surrounding the pile shaft, particularly it is observed in cohesive soils. Although several empirical and analytical models have been proposed to estimate pile setup, their practical implementation in foundation design remains limited due to uncertainties associated with soil conditions, pile geometry, resistance variability, and time dependent behavior. To address some of these uncertainties, this study collected 221 pile load test data at the End of …

Spieltrieb, Edward F. Newcomb

College of Graduate Studies: Theses & Dissertations

This thesis investigates the creative and pedagogical intersections of nostalgia, play, and neurodivergent experience through a mixed-media studio practice. Grounded in Friedrich Schiller’s concept of Spieltrieb—the human drive to play as a balance between sensual and rational impulses—this work explores how childhood memory, instinct, and impulsive mark making inform both artistic production and art education.

Drawing on theoretical frameworks by Susan Sontag and John Berger, the work resists overinterpretation in favor of sensory immediacy, inviting viewers into direct, embodied encounters with material form. Sontag’s critique of mimetic representation and Berger’s analysis of reproducibility and context inform a practice that …

The Monster Consuming American Education: An Ethnodramatic Exploration Of Standardized Testing And Student Stress, Jennifer Bagley

College of Graduate Studies: Theses & Dissertations

This study looks at how elementary students experience Standardized Testing, focusing on the emotional and physical effects of the Georgia Milestones Assessment System (GMAS). Most research on high-stakes testing focuses on scores, accountability, and policy, but fewer studies look at how students actually describe these experiences. Grounded in Cultural Studies and informed by Critical Pedagogy, this study examines how students interpret and make meaning of their testing experiences within the broader culture of accountability and standardized assessment. This study focuses on student voices to better understand what testing feels like for them and how they make sense of it in …

Evaluating Benthic Macroinvertebrate Communities In Streamside Management Zones In Private, Working Forests, Haley Vaglienti

College of Graduate Studies: Theses & Dissertations

Forestry operations can alter riparian vegetation and increase sediment and nutrient inputs to streams, affecting water quality and aquatic biota. Forestry best management practices (BMPs) including streamside management zones (SMZs) are designed to mitigate those effects by reducing sediment delivery and moderating temperature, flow, and nutrient regimes. We assessed ecological integrity at 24 intermittent stream sites with SMZs in private, working forests across the Piedmont and Southeastern plains of Georgia. At each site, we conducted physical habitat evaluations and characterized benthic macroinvertebrate assemblages. Sites represented a gradient of habitat conditions, SMZ widths, and pine stand ages, allowing for comparisons of …

Conceptual Concerns Regarding The Content Validity Of The Construct Of Gender Dysphoria In The Diagnostic And Statistical Manual Of Mental Disorders, Fifth Edition, Text Revision, Waverley Vesely

Theses and Dissertations

The diagnostic classification of gender dysphoria in the DSM-5-TR elicits a number of clinical, political, and philosophical concerns, ranging from those that are diagnostic and taxonomical in nature to those that fall within the domains of ontology, phenomenology, and hermeneutics. Part of the reason for the complexity of studying the diagnostic and nosological validity of gender dysphoria as an extant diagnostic classification is that, unlike many disorders, gender dysphoria is inextricably tethered to identity. While the recent change from gender identity disorder to gender dysphoria has nominally removed the status of disorder, in practice, both clinicians and the general population …

Research on interventions designed to increase posttraumatic growth (PTG) among interpersonal trauma survivors is limited. The purpose of this study was to examine the impact of a six-week trauma-informed mindfulness meditation intervention on PTG. Additionally, I examined outcomes of posttraumatic stress (PTS) and loneliness, as well as analyzed the variables of dispositional mindfulness, hope, spirituality, and self-compassion to understand their potential role as mechanisms of change within the intervention on PTG. To answer these research questions, I conducted a randomized controlled trial study with 113 adults from a community sample who reported experiencing interpersonal trauma. Utilizing linear mixed modeling and …

The Relationship Between Symptom Catastrophizing And Sociocultural Factors Among Adults With Persistent Sympathetic Activation Syndromes, Whitney M. Redemer

Theses and Dissertations

Persistent Sympathetic Activation (PSA) has emerged as a potential unifying mechanism underlying a range of complex chronic health conditions yet remains poorly characterized within biomedical and psychosocial research. Limited research has delineated how PSA manifests across diverse populations or how diagnostic and sociocultural factors shape lived experiences of this phenomenon; thus, the objective of the present study was to examine whether diagnostic certainty – operationalized as provider-confirmed versus self-suspected PSA-related diagnoses – is associated with symptom catastrophizing, and whether this relationship varies as a function of sociocultural factors. Drawing on data from a larger study aimed at characterizing the lived …

Dimension Reduction Involving Exogenous Variables With Applications In Manufacturing And Healthcare, Linxi Li

Theses and Dissertations

High-dimensional data analysis presents diverse challenges, including the curse of dimensionality, the complexities of working with datasets that combine large feature spaces with limited sample sizes, and difficulties in identifying meaningful relationships among variables. As datasets grow in size and complexity across different fields, it is increasingly important to develop practical approaches for extracting essential information from such data. Dimension reduction methods address these challenges by alleviating the effects of high dimensionality, enhancing the ability to reveal hidden patterns, and uncovering latent structures within the data to support further analysis. Some methods reduce dimensionality while preserving all relevant information, offering …

Commissioning & Daily Qa Of Converted Linac For Electron Flash, Tomaj Javidtash

Theses and Dissertations

Ultra-high dose rate (FLASH) radiotherapy has demonstrated promising normal tissue sparing in preclinical studies; however, the lack of standardized dosimetry, commissioning, and quality assurance (QA) methodologies remains a major barrier to its reproducible and safe implementation. In particular, conventional clinical commissioning and QA protocols are not directly applicable at FLASH dose rates due to challenges associated with detector response, dose-per-pulse effects, and beam control limitations.

This thesis presents the commissioning of a converted Varian 21EX linear accelerator for electron FLASH operation within the Division of Medical Physics at the Virginia Commonwealth University (VCU) Department of Radiation Oncology. Comprehensive beam characterization …

Lutetium-177 (Lu-177) is widely used in radionuclide therapy, where accurate activity measurement prior to administration is essential for safe and effective treatment delivery. However, variability in dose calibrator response due to measurement conditions and source geometry remains a practical challenge in routine clinical settings. This study presents a practical clinical calibration strategy under real-world constraints for Lu-177 activity measurement using standard nuclear medicine instrumentation. A vial-based approach was implemented using a well-type ionization chamber (Capintec CRC-15R) to evaluate measurement repeatability, temporal stability, and geometry dependence. All measurements were performed under consistent conditions with appropriate decay correction applied using the physical …

A Mutant Perfect, Amelia R. Baxter

Theses and Dissertations

A Mutant Perfect examines how embodied knowledge can be made visible and transmissible through ceramic figures. The research asks what forms emerge when making is understood as a mode of thinking rather than a vehicle for pre-formed ideas, and how those forms might activate somatic recognition in a viewer. The primary method is coil-built ceramic sculpture. Color is applied in layered coats and removed by hand-sanding to expose varying strata beneath, producing a speckled, worn surface. In a second approach, pigment is built directly into the clay body through coil construction, making color structural rather than applied. Narrative prose and …

Daisyworld, Eva Foldy

Theses and Dissertations

Daisyworld explores how painting can represent ecological and sociopolitical crisis without relying on narratives of total collapse as a catastrophic end, instead framing the present as a condition of ongoing, uneven transformation. Drawing on ecological models of adaptation, interdependence, and planetary self-regulation, it uses plant fasciation as both a biological reference and speculative metaphor for distorted yet generative forms of survival. Situating painting within a broader history of visual culture, it examines how images function as accessible systems of knowledge while challenging colonial and human-centered modes of representation. In dialogue with contemporary, systems-based artistic practices, the project repositions painting as …

Spilt Milk, Fatima Kaleem

Theses and Dissertations

Spilt Milk explores how institutional discipline is rehearsed across the Pakistani home, school, and television soap opera. These seemingly domestic spaces converge at the military-industrial complex, where media propaganda (ISPR) and consumer commodities collaborate to manufacture a unified national identity.

Through an installation of school desks and re-fabricated cereal boxes, this project examines the ‘cereal/serial’ as a site of ideological consumption. By refabricating these boxes with embroidery, drawing, lace, and synthetic hair, the work subverts state-mandated narratives. These material interventions replace assembly lines with spills of hair and sweat to highlight the vulnerability of the body under surveillance. This project …

In-Between Echoes, Jiayi Liang

Theses and Dissertations

In this dissertation, I explore memory, diaspora, labor, and intergenerational trauma through constructed photography and experimental film. Informed by Homi K. Bhabha’s concept of the Third Space, I examine how identity is shaped through displacement, cultural negotiation, and inherited memory. Drawing from my relationship with my grandmother and my experience as a Chinese woman living in diaspora, I consider labor as both survival and care, tracing how domestic gestures and emotional structures continue across generations. Through collage, reconstruction, and animation, I rework fragments of family archives, colonial landscape imagery, and personal photographs to address grief, racialized perception, belonging, and the …

Between The Veins: Materializing Memory In The Age Of Digital Storage, Alice Mohammed Aslem

Theses and Dissertations

What happens to a childhood stored behind a password? This thesis began with a simple moment of scrolling through my son’s photographs on my phone. As the images multiplied, they began to lose clarity, turning into an overwhelming digital archive. This made me ask: What kind of memories am I preserving for him?

Having grown up between analog and digital worlds, Between the Veins explores how I navigate memory through material objects and digital archives. Using weaving, images are transferred onto screw pine and palm leaves. In this process, digital files of his childhood are translated into organic fibers of …

Plumbed 3-Manifolds And Neumann Moves, Noah J. Pope

Theses and Dissertations

We give a constructive proof that every weakly negative definite plumbing tree can be transformed into a negative definite one by a finite sequence of Neumann moves. The argument combines Neumann’s plumbing calculus with the diagonalization algorithm of Duchon, Eisenbud, and Neumann, which extracts the eigenvalues of the framing matrix directly from the combinatorics of the tree. We show that any positive eigenvalues are supported on linear branches and can be eliminated systematically via controlled applications of Neumann moves. This provides an explicit algorithm reducing weakly negative definite plumbing trees to negative definite ones.

The Transition From School To Work For Students With Emotional And Behavioral Disorders: Examining The Lived Experiences Of Students In Private Day Schools, Gabrielle S. Pickover

Theses and Dissertations

This qualitative phenomenological study examined the lived experiences of young adults with Emotional and Behavioral Disorders (EBD) as they transitioned from private day school settings into sustained employment. Guided by Schlossberg’s Transition Theory, the study explored participants’ perceptions of the barriers, supports, and strategies that shaped their transition experiences. Data were collected through twelve semi-structured interviews with six participants who maintained at least one year of continuous employment following high school. Analysis revealed four primary themes: structure as a stabilizing force, resilience developed through adversity, experiential learning as a pathway to employment, and employment as identity and independence. Findings suggest …

Substance Use Behaviors And Treatment Engagement In Individuals With Severe Psychopathology With And Without Comorbid Obesity, Rachel M. Madera-Arnold

Theses and Dissertations

Research has found significantly higher rates of both substance use and obesity among individuals with SMI compared to population samples which in turn can lead to worsening health outcomes. Despite this, there is limited research on the co-occurrence of obesity, substance use, and SMI and how these conditions may interact to affect patient outcomes. In addition, there are many gaps in the research regarding the relationship between substance use and body weight, appetite and/or eating behaviors. This study conducted a secondary analysis of the NSDUH 2021 survey that characterized substance use and disorders among individuals who had severe psychopathology, examined …

Cb1 Allosteric Modulation: Preclinical Insights Into Therapeutic Potential And Misuse Liability, Mohammed A. Mustafa

Theses and Dissertations

Cannabinoid type-1 (CB1) allosteric modulators represent a promising approach to modulate CB1 receptor signaling by binding to distinct receptor sites, without producing adverse cannabimimetic and dependence-related effects associated with Δ9-tetrahydrocannabinol (THC) and other CB1 agonists. This dissertation investigates the pharmacological, behavioral, and dependence-related profiles of CB1 allosteric modulators for their therapeutic potential and misuse liability. Presented here, the chiral CB1 positive allosteric modulator (PAM) ZCZ011 was resolved into its R- and S-enantiomers and characterized across in vitro and in vivo assays. Both enantiomers enhance CB1 agonist activity and produce intrinsic effects in vitro. Behaviorally, they produce antinociceptive effects in the …

Munajat: Design As A Dialogue With The Divine, Shawky Abdalla

Theses and Dissertations

Contemporary design discourse remains grounded in functional, seemingly user-centered paradigms, often neglecting what lies beyond the tangible within a human experience. This research challenges such frameworks by positioning design as a dialogue with what exceeds the physical, moving toward the experiential, where meaning precedes and informs form. Drawing on Islamic philosophy, particularly the relationship between zahir and batin (outward form and inward meaning), the study repositions design as a medium for remembrance (dhikr) rather than mere utility.

Through a critique of modernist and postmodernist principles, the research proposes a series of objects that engage with memory, introspection, and transcendence in …
