2020-Current year OA Pubs

OBJECTIVES: Children with differentiated thyroid cancer (DTC) often present with lung metastases but historically have good outcomes. Radioactive iodine (RAI) is commonly used to treat these children. Given the rarity of this condition, little evidence detailing long-term outcomes and risk of radiation pneumonitis exists.

METHODS: We conducted a retrospective analysis of patients < 20 years old who received RAI for DTC lung metastases between 1973 and 2018. Disease-free survival (DFS) was calculated from diagnosis to last follow-up. Overall survival and rates of acute and late radiation pneumonitis were determined by chart review and obituary searches.

RESULTS: Sixteen patients met eligibility criteria. Fourteen presented with thyroid, nodal, and lung disease; one presented with thyroid and nodal disease with nodal and lung recurrence; and one presented with thyroid-only disease with nodal and lung recurrence. All patients underwent thyroidectomy, 10 underwent neck dissection, and four underwent …

High‑fidelity prototypes were developed to address these issues, emphasizing consistency, reduced cognitive load, transparent navigation, and improved interaction flow. These prototypes informed the implementation of redesigned interface components, including streamlined menus, multi‑step registration forms …

Impacts On Knee And Ankle Joint Stiffness During Walk And Stair Negotiation For Individuals With Acl-R And Oa, Genavieve J. Golightly, Nicholas L. Hunt, Tyler N. Brown

2026 Undergraduate Research Showcase

Knee injuries, including those requiring anterior cruciate ligament reconstruction (ACLR), are associated with numerous degenerative outcomes, including the progression of osteoarthritis (OA). Although reconstructive surgery and physical therapy are available treatment options, OA progression following knee joint injury continues to leave many individuals facing premature joint degeneration. Increased joint stiffness is a common consequence of knee joint injury and is seen in many patients who have undergone ACLR, and may be a contributing factor in the acceleration of OA by creating an environment of concentrated stress on knee cartilage, thereby promoting joint degeneration. It is unclear whether knee injuries alter …

The radii were determined to be 76 pm …

Click Reactions With Surface-Bound Phosphonate Films Toward An Electrocatalytic System For Carbon Dioxide Reduction, Iaroslavna Kovalenko, Emma J. Goehner, K. Nicole Crowder

Research and Creativity Symposium

One way to electrochemically reduce CO₂ is to use modified electrode surfaces with bound transition-metal electrocatalysts. Optimal conditions for modifying copper surfaces with a 1.0 mM solution of (2-azidoethyl) phosphonic acid in acetone have been identified, forming a self-assembled monolayer (SAM) via the tethering by aggregation and growth (T-BAG) method. The SAM protects the copper electrodes from oxidation or side reactions on the copper surface. The copper-catalyzed azide-alkyne cycloaddition (CuAAC) click reaction between the terminal azide group on the phosphonate and the terpyridine ligand has been successfully carried out on the copper surface. This terpyridyl ligand was then used …

“Tolling For The Outcast”: A Therapeutic Jurisprudence Consideration Of The Relationship Between The Americans With Disabilities Act, Death Row Conditions, And Capital Punishment, Michael L. Perlin, Esq., Talia Roitberg Harmon, Maren Geiger, Chelsea Henning

San Diego Law Review

The press has regularly reported on the level of abysmal conditions on death rows in those states that have retained capital punishment. Death-row prisoners are often incarcerated in solitary confinement, and are subject to much more deprivation and harsher conditions than other prisoners. As a result, many experience declining mental health, and it has become clear that persons with mental illness are disproportionately put to death. Some litigants have turned to the Americans with Disabilities Act (ADA) as a potential source of relief; the Supreme Court’s decision in Pennsylvania Department of Corrections v. Yeskey underscored that the act’s language “unmistakably …

Thou Shall Not Compel Speech: Public Educators’ Free Speech Rights In The Face Of Louisiana’S “Ten Commandments” Law And Other Rules Compelling Private Expression From Public School Teachers, Kailey A. Olsson

San Diego Law Review

First Amendment jurisprudence has significantly evolved within the past decade as the Supreme Court has expanded religious protections, further developed the Compelled-Speech Doctrine, and narrowed what public school activities are considered violations of the Establishment Clause.  There is no other U.S. Supreme Court case that illustrates these monumental shifts in First Amendment interpretation quite like Kennedy v. Bremerton School District.  Writing for the majority, Justice Gorsuch found that a public school district could not suppress the personal religious expression of a football coach, even when that coach led a prayer activity with other football players and within view of other …

The Atmospheric Effects On The Extratropical Transition Of Hurricane Sandy, Natalie Paone

Ocean Engineering and Marine Sciences Student Publications

• Hurricane Sandy formed in the Caribbean in late October 2012 and intensified to a Category 3 hurricane before making landfall in Cuba and later New Jersey (Blake et al., 2013). Sandy caused approximately $68.7 billion in damages and over 250 fatalities, making it one of the most impactful storms in U.S. history. 
• During extratropical transition (ET), tropical cyclones interact with midlatitude systems, leading to structural changes such as expansion of the wind field, development of frontal boundaries, and increased baroclinicity (Hart and Evans, 2001). Sandy is a key example of a hybrid cyclone where ET did not weaken impacts but …

Tiny Engineers: How Polycheateworms Can Extend Sedimentary Oxic Layers And Create Better Seagrass Habitats, Natalie Spohn

Ocean Engineering and Marine Sciences Student Publications

The Indian River Lagoon (IRL) is a shallow, well mixed estuary on the East Coast of Florida. Presently, the IRL is suffering eutrophication due to a cycle of harmful algal blooms (HABs) that deplete the water column of oxygen (2,5). Deposition of organic matter from HABs in the sediment leads to reduced sedimentary oxygen, continuing to support the cycle of eutrophication through benthic-pelagic coupling (1,5). Anaerobic sedimentary conditions can increase concentrations of ammonium and sulfide, leading to seagrass loss (3,4,6,7,10). Bioturbation by infauna can extend the oxic layer of sediments, promoting aerobic processes and helping to remove nitrogen and sulfur …

Ontogeny Of Microbial Community Structure In Shoal Grass Grown In Biochar-Amended Sediments, Sajeda Slhoub, Nicole Katz, Joey Ciocher, Jack Denvir, Jenisse Louis, Katelynn Zagami

Ocean Engineering and Marine Sciences Student Publications

The Indian River Lagoon (IRL) is one of the most biologically diverse estuaries in the United States and contributes over $55.4 billion annually to Florida’s economy. Since 2010, more than 52% of the IRL seagrass meadows have been lost, reducing both the ecological and the economic potential of this ecosystem. Biochar, a stable carbon material produced by pyrolysis, added to soil enhance organic productivity perhaps because of increased microbial activity in the soil (Lehmann et al., 2017). Our study evaluates the use of biochar to grow resilient strains of seagrass for ecosystem restoration in the IRL.

Thermoelectric Migraine Cooling Cap, Emily Ralston

Ocean Engineering and Marine Sciences Student Publications

Migraines affect millions of people and can cause serious pain and discomfort. Many people use ice packs or cooling wraps to try to reduce the pain, but these only stay cold for a short amount of time. Because of this, there is a need for a cooling system that can provide longer and more controlled cooling. This project focuses on designing and building a wearable cooling cap that uses thermoelectric cooling technology. The goal is to create a system that can cool the head while moving heat away toward the neck area and help reduce migraine discomfort.

Recycling Spent Brewing Yeast As A Shrimp Feed Supplement, John Denvir

Ocean Engineering and Marine Sciences Student Publications

The aquaculture industry relies heavily on commercial fish feed, which accounts for over 50% of production costs and limits farm profitability worldwide[1]. Breweries generate about 3 gallons of high-strength wastewater per gallon of beer produced, much of it discarded as an oxygen-depleting pollutant from spent yeast[2]. Therefore, this project tests recycling spent brewer's yeast into a sustainable fish feed supplement to cut aquaculture costs and divert brewery waste from waterways, promoting circular food systems.

Gamma Ray Burst Afterglow Slopes, Brian Robbins

Aerospace, Physics, and Space Science Student Publications

The standard models for gamma ray bursts (GRBs) typically assume that shockaccelerated electrons follow a power law distribution of energies. However, this behavior is not what some gamma ray bursts show. In this project, it is suggested that the presence of thermal electrons causes temporal and spectral structure across the afterglow, which is significantly different from models assuming a pure power-law distribution of electrons. To model the afterglows, we decide on a large number of samples of GRBs from the Swift database and obtain the temporal and spectral indices at arbitrary times. By finding the temporal and spectral indices at …
