The removal efficiency was 91.75% for WWTP A and 90.32% for WWTP B, with no statistically significant difference (p > 0.05). WWTP A employed advanced treatment units, whereas WWTP B used a conventional pond-based system. MPs were …

Untangling Ai Openness, Parth Nobel, Alan Rozenshtein, Chinmayi Sharma

Articles

The debate over AI openness—whether to make components of an artificial intelligence system available for public inspection and modification—forces policymakers to balance innovation, democratized access, safety, and national security. By inviting startups and researchers into the fold, it enables independent oversight and inclusive collaboration. But technology giants can also use it to entrench their own power, while adversaries can use it to shortcut years and billions of dollars in building systems, like China’s DeepSeek, that rival our own. How we govern AI openness today will shape the future of AI and America’s role in it.

These transformations were later applied to the test set. Principal …

Hepatocyte Peroxisome Biogenesis And Phytol-Induced Metabolic Stress In Liver Disease, William Galloway

Theses, Dissertations and Capstones

Hepatocyte peroxisomes are required for metabolism of phytol-derived branched-chain fatty acids through the ACOX2-SCPx beta-oxidation pathway. This study tests whether hepatocyte-specific deletion of PEX16 (Pex16^Alb-Cre), which eliminates peroxisome biogenesis, sensitizes the liver to phytol-induced injury. The Pex16^Alb-Cre mice and their normal control Pex16^fl/fl mice were fed the Lieber-DeCarli liquid with or without 0.1 percent phytol for eight weeks. Serum alanine aminotransferase (ALT) and liver index were measured. Liver sections were stained with hematoxylin and eosin and Masson’s trichrome. Immunoblot analysis of peroxisomal enzyme expression was also performed. Phytol had no effect in Pex16^fl/fl mice as …

Anaerobic Digestion Of Variable, Heterogeneous Organic Wastes Under Changing Operational Conditions And Bioaugmentation: Impacts On Process Performance And Microbiome Dynamics, Victoria Holliday

Theses and Dissertations--Biosystems and Agricultural Engineering

Expanding the adoption of anaerobic digestion (AD) is limited by system instabilities caused by feedstock composition and variability. Understanding how changes in feedstock and operational parameters influence microbiome dynamics is essential for developing biology-driven strategies to improve digester stability.

Two semi-continuous reactors, an experimental and a control, operated over 39 weeks across five phases with varying feedstocks and organic loading rates. Substrate-specific enrichment cultures were developed for bioaugmentation and implemented in select phases to assess its impact. Both reactors exhibited similar performance, transitioning through periods of stability, stress, and recovery in response to operational changes. Corresponding shifts in dominant taxa …

Investigating The Viability Of Fully Online Asynchronous Physics Instruction In Formal Education, Clifton W. Massey-Noel

Physics Dissertations

In this dissertation we present results from two consecutive investigations into the fully online asynchronous modality in Physics Education. We first discuss the efficacy of a fully online asynchronous section of Modern Physics held in Fall 2024. The asynchronous section is compared with four prior partially-flipped sections of the same class, two of which were held in-person, and two of which were held synchronously online. Results suggest that all three modalities can be made to be about equally as effective. We also discuss the efficacy of a fully online asynchronous section of Calculus-Based Introductory Mechanics held in Fall 2025. The …

Sexually Dimorphic Effects Of Gpnmb Modulation On Vertebral Bone Mass Regulation And Intravertebral Disc Health, Hakem Altawil, Fayez Safadi

Williams Honors College, Honors Research Projects

Osteoporosis and vertebral degeneration are major contributors to musculoskeletal morbidity, yet the molecular mechanisms regulating vertebral bone and intervertebral disc (IVD) homeostasis remain incompletely understood. GPNMB (osteoactivin) has been identified as a regulator of bone remodeling, though its role in spine health is unclear. This study evaluated the effects of GPNMB deficiency on lumbar vertebral bone microarchitecture and IVD integrity in a sex-dependent context.

Six-month-old male and female wild-type (WT) and GPNMB knockout (KO) mice were analyzed using micro–computed tomography (µCT) of lumbar vertebrae (L4–L6) and histological assessment of the L5–L6 IVD. KO males exhibited increased bone volume fraction, bone …

Faculty Publications - Criminal Justice Sciences

This study examines filicide, the killing of a child by a parent or parental figure, using 25 years of data (1999–2023) from the National Incident-Based Reporting System (N = 3,974). Multinomial logistic regression was used to analyze variations in offender, victim, and incident characteristics across four victim age categories: neonaticide (within 24 hr of birth), infanticide (1–364 days), child filicide (1–17 years), and adult filicide (18+ years). Results reveal significant differences in offender age, sex, race, weapon use, and victim demographics. Neonaticide is most often associated with younger female offenders and the use of personal weapons, while adult filicide …

Reading Wars, Don Herzog

Books

Once again, we’re fighting wars over reading. Who gets to read? What do they get to read? These days, the right is obsessed with removing LGBTQ books from school and public library shelves and ensuring students read only the Correct version of American history. The left is obsessed with eradicating right-wing fantasies, not to mention outright lies, from the internet, and with airbrushing or even purging racist texts. You don’t have to stoop to whataboutery to notice a suspicious resemblance. But once again is wrong. We’ve always fought these wars, even if the enemies come and go. In this book, …

Covering The Care: The Fourth Trimester, Susy Hawes

All Materials

The weeks following the birth of a baby are often described as a time of extremes: profound joy paired with deep exhaustion, vulnerability, and adjustment. For birthing people, this period involves physical recovery from childbirth, dramatic hormonal shifts, disrupted sleep, learning to feed and care for an infant, and navigating major emotional changes. While some new parents have strong support systems, others face isolation, housing instability, or unsafe home environments. This critical 12-week period after birth is now widely known as the “fourth trimester.” Although the language is new, the reality is not. Across cultures and history, the postpartum period …

Reading Between The Lines: Representations Of Dyslexia In Young Adult Literature, Carli B. Gauvin

Honors Theses and Capstones

While dyslexia affects upwards of 20% of the population, this learning disability is not commonly brought up in young adult literature. This lack of representation negatively impacts those with dyslexia, who often fail to find themselves in the books they read, and readers in general, who are given fewer opportunities to gain insight into the learning disability. Young adult books that do discuss dyslexia can be at risk of portraying the learning disability in an unfavorable light, which can make dyslexic readers feel undervalued in society and can introduce misconceptions about dyslexia to all readers. It is crucial to analyze …

The Lie Group Basis Of Neuronal Membrane Architecture: Why The Hodgkin–Huxley Equations Take Their Form, Robert Melendy, Daniel Blue

Faculty Publications - Department of Electrical Engineering and Computer Science

The Hodgkin–Huxley equations have successfully described neuronal excitability for over seventy years, yet their mathematical structure remains empirically justified rather than theoretically explained. Why are gating variables bounded between 0 and 1? Why does sodium conductance depend on m³h rather than other combinations? Why does potassium depend on n⁴? Why do all rate functions contain exponential voltage dependencies? Why are the kinetics first-order? We demonstrate that these structural features arise naturally from three fundamental physical symmetries governing ion channel dynamics: the compactness of conformational state space, the scaling invariance of membrane conductance, and temporal translation invariance. …

Advancing Lipidomics Through Fluoroalcohol-Induced Multiphase Fractionation And Orthogonal Lc×Lc–Ms Detection, Md Al Amin

Chemistry & Biochemistry Dissertations

Comprehensive characterization of the lipidome remains a significant analytical challenge due to the immense structural diversity, wide dynamic range, and complex physicochemical continuum of lipid species. Conventional extraction methods, such as those by Bligh–Dyer and Folch, and one-dimensional liquid chromatography (1D-LC) often fail to resolve this complexity, leading to chromatographic overlap, severe ion suppression, and limited coverage of low-abundance or highly hydrophobic species. This dissertation addresses these bottlenecks by establishing a separation-driven analytical framework that integrates novel fluoroalcohol-induced multiphase systems (FAiTPS) with orthogonal multidimensional liquid chromatography–mass spectrometry (LC×LC–MS).

The core of this research is the development and physicochemical characterization of …

Raining Plastics: Quantification Of Atmospheric Deposition Of Plastic And Anthropogenic Particles Into An Estuary Of National Significance With The Assistance Of Citizen Scientists, Linda Walters, Madison Serrate, Tara Blanchard, Paul Sacks, Fnu Joshua, Lei Zhai

Research Data and Datasets

Globally, little is known about the dispersal of microplastics (MP) and anthropogenic particles (AP) via atmospheric deposition (AD) into water bodies. Correlating AD to the large number of MP in estuaries is challenging but an important first step toward reducing this form of pollution. A previously published model of the surface waters of the Indian River Lagoon (IRL, east central coast of Florida, USA) estimated it contained 1.4 trillion microplastics. To determine if AD could produce this much plastic deposition, we deployed passive AD collectors throughout a 145 km2 area at three site types with assistance from citizen scientists. We …

Crispr Transgenic Clytia Hemisphaerica As A Vector For Toxin Delivery In A Zebrafish Melanoma Model, Theodore G. Paz

Theses, Dissertations and Culminating Projects

The jellyfish Clytia hemisphaerica has the potential to be used in cancer therapies with the discovery of potential active toxin target regions to be modified for use. The program Venomix is a Uniprot-based database that was utilized in this experiment to generate likely flagged hit regions using Clytia hemisphaerica CDS files run against its database of terrestrial toxins (Furuno et al., 2003; Macrander et al., 2018). By themselves they are indeterminate as to whether they are active toxin region hits (Macrander et al., 2018). With further analysis such as toxin homology in closely related, annotated marine taxa and accounting for …

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 …

Varying Dna Methylation Patterns In The Florida Sand Skink (Plestiodon Reynoldsi) In Relation To Fire Histories, Victoire Hj Litre

College of Graduate Studies: Theses & Dissertations

Epigenetics is the study of changes in phenotype not caused by changes in DNA sequence. DNA methylation is the most well-studied epigenetic mechanism in an ecological context. Reptiles use DNA methylation to respond to environmental stressors and differences among habitats. The Florida Sand Skink (Plastidome reynoldsi) is federally listed as a threatened species. They are endemic to the threatened, fire-dependent Florida scrub habitat. As they persist in burned habitats, the Florida Sand Skink must be able to rapidly respond to wildfires. To better understand how the Florida Sand Skink adjusts to fire-driven habitat changes, it is important to …
