Machine Learning In Fundamental Physics: From Early Universe Signatures To Qcd Evolution, Brandon Stevenson

Physics Theses and Dissertations

In both cosmology and small-x quantum chromodynamics, the relevant theoretical predictions are well-defined but expensive to evaluate repeatedly over broad parameter spaces or large ensembles of simulated data. The central question of this thesis is when machine learning can accelerate those calculations without weakening the reliability of the final physics conclusions. The thesis develops and tests this idea in three settings. First, it studies the Derivative Approximation for Likelihoods (DALI) as a means of diagnosing when Fisher-matrix forecasts cease to be trustworthy in cosmological parameter inference. Second, it investigates graph-based spherical neural networks for estimating primordial non-Gaussianity directly from simulated …

Antitrust And Economic Liberty, Doha Mekki

Center for Law and the Economy

Over the last few years, antitrust plaintiffs have won important victories in cases against digital platforms. They’ve won important cases involving real estate associations, elite private colleges, sports leagues, pharmaceutical companies, pork processors, and health insurers. In some cases, they have secured record-breaking jury verdicts and redress for harmed individuals.

The U.S. Department of Justice’s Antitrust Division has been active too. Last year, a federal court held that Google illegally maintained monopolies in general internet search and related search advertising markets. That case is about access to the information we see and use to make decisions about how we want …

The Revival Of Section 5: A Return To The Ftc’S Roots In A Time Of Democratic Crisis, Shaoul Sussman

Center for Law and the Economy

On November 10, 2022, the Federal Trade Commission (FTC or the “Commission”) issued a policy statement on the scope of unfair methods of competition under section 5 of the Federal Trade Commission Act (FTCA). This policy statement marked a significant shift, reviving a broad interpretation of the agency’s authority to police anticompetitive conduct. The antitrust defense bar reacted with alarm, arguing that the principles are overly ambiguous and lack guidance. This Essay contends that reaction is misplaced. The statement draws on a rich body of U.S. Supreme Court and circuit court precedent that the antitrust bar seems to have largely …

A Descriptive Survey Of Reef Fish Biodiversity At The Erojacks Artificial Reef, Dania Beach, Florida, Daniella Michelle Acosta Reyes

Undergraduate Student Symposium

South Florida has one of the highest biodiversity's of reef-associated fish species in the United States. Reef systems play a crucial role in sustaining regional biodiversity. Ongoing declines in natural coral reef systems caused by climate change, coastal development, and other anthropogenic factors have increased the reliance on artificial reefs as alternative structures for coral and fish communities to aggregate. Artificial reefs play an important role in maintaining marine biodiversity and provide habitat for reef-associated fishes. The Erojacks Reef, an artificial reef system located off the coast of Dania Beach, South Florida acts as a gathering site for reef fishes. …

A Review Of Reproductive Cycling In Batoid Dentition Morphology With New Data On Two Dasyatid Stingrays From The Western North Atlantic, Lacey Adamik

Undergraduate Student Symposium

Elasmobranchs continuously replace their teeth throughout their lifespan, allowing changes in tooth morphology associated with feeding and reproduction to occur. In many batoid species, males will bite females during pre-copulatory behavior, placing male dentition under selective pressure to meet the demands of both diet and grasping of females. Previous research has documented sexual dimorphism and seasonal dentition changes in several species of batoids, suggesting that this phenomenon is widespread. Much of this research is observation-based, and quantitative studies of dentition are limited, particularly in pelagic species. Pelagic Stingray (Pteroplatytrygon violacea) specimens were previously collected by commercial fishermen, and …

The Role Of Hip Internal Rotation And Ground Reaction Forces On Lower Back Pain In Amateur Golfers, Katrina Arndt

Undergraduate Student Symposium

Lower back pain (LBP) is the most common musculoskeletal injury amongst golfers; the high velocity and repetitive motion of the golf swing on the lumbar spine leads to substantial compressive and torsional forces, making LBP primarily and overuse injury. An additional risk factor for LBP is limited lead hip internal rotation (LHIR), which forces the lumbar spine to compensate through excessive rotation. The golf swing also relies heavily on the efficient transfer of energy generated from the ground through the lower body, a process quantified by ground reaction forces (GRFs). While existing research has separately examined LBP and GRFs, there …

Functional Annotation Of Gordonia Phage Minor Tail Proteins Using Alphafold And Structural Homology Searches, Harani Athwale, Mitchell Thenor

Undergraduate Student Symposium

Bacteriophages are viruses that infect bacteria. The basic phage structure consists of a DNA or RNA genome encased in a capsid protein shell. Some may also have a tail, important for attachment and genome delivery into the bacterial host. Recently, the structure of mycobacteriophage Bxb1 was characterized and determined to have 10 minor tail proteins, each assigned a unique function. The genomes of Gordonia rubripertincta phages Fribs8, Genamy16, Alyssamiracle, and NovaSharks were annotated, depicting several minor tai proteins. However, the specific functions were not determined. Therefore, the goal of this research was to assign a specific function to the minor …

Reproductive Experience Mitigates Cognitive Aging In A Mouse Model Of Alzheimer's Disease, Esperanza Barrios, Chana Vogel, Tej Chaudhari, Anna Roy, Shruthi Senthil, Greeshma Thomas

Undergraduate Student Symposium

Alzheimer's disease (AD) is a devastating neurodegenerative disorder that lacks effective treatment. Despite women having approximately twice the risk for developing AD, few studies have investigated sex-specific factors contributing to disease vulnerability. Among women, motherhood appears to be protective, although results are mixed, and this relationship could be explained by a third variable (e.g., genes) influencing both disease risk and fertility or fecundity. During an experiment directly tested the effects of motherhood by manipulating access to male breeders and examining neurodegeneration and cognitive aging in control (B6129) and transgenic mice used to model AD (3xTg-AD mice), we also compared reproductive …

Xct (Slc7a11) Regulationl Lessons From Cancer Research, Sravika Chirla, Rahul Pandit

Undergraduate Student Symposium

xCT is an amino acid antiporter that imports cystine in exchange for glutamate with a 1:1 ration in a concentration-dependent manner. Once inside the cell, cystine is quickly reduced to cysteine, the rate-limiting substrate for the main cellular antioxidant, glutathione. The function of xCT has been highlighted by the discovery of a new type of cell death, known as ferroptosis. Ferroptosis is a distinctive form of programmed cell death triggered by lipid peroxidation and the accumulation of reactive oxygen species, leading to cell damage and death. Numerous classes of cancers have shown overexpression of xCT, which correlates with worse outcomes …

Mediterranean Diet Adherence And Bone Density: No Link In University Cross-County Athletes, Auston Hsieh, Sathvi Gandra, Kiana Medina

Undergraduate Student Symposium

Bone stress injuries are common among collegiate cross-country runners, occurring at rates of 28.6 and 16.1 per 100,000 athlete-exposures in women and men, respectively. Adequate, individualized dietary patterns have been shown to reduce bone stress injury risk by supporting bone mineral density (BMD); however, there is a lack of consensus on the most advantageous dietary pattern. The Mediterranean diet (MD) has been associated with improved BMD in general populations; however, its relationship to BMD in collegiate athletes remains unclear. Therefore, this study assessed the association between MD adherence and BMD in university competitive cross-country runners. Nineteen participants (sex, 7 male, …

Glioblastoma multiforme (GBM) or Grade IV glioma is a very aggressive form of brain tumor with an overall survival rate of 15 months. The tumor contains glioma stem cells (GSCs) that are resistant to existing therapies. Long non-coding RNAs such as DNA methylation are implicated in epigenetic dysregulation of GBM and GSCs. In this study, we screened lncRNAs with altered DNA methylation in both tumor cells and GSCs compared to normal neural cells using 450K methylation array data. We identified 508 methylation sites (320 lncRNAs) that were either hypermethylated (or gained methylation) or hypomethylated (lost methylation) in GBM and GSCs. …

Sleep Disturbance, Menopause, And Alzheimer's Risk In Women, Shreya Kempuraj

Undergraduate Student Symposium

Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by neurodegeneration, behavioral changes, cognitive impairment, and loss of sleep quality. Women are at a greater risk of developing dementia and AD during the lifetimes because women live longer than men on average and other factors. The duration and quality of sleep are associated with a healthy brain, especially during aging. Impaired and poor sleep is both an early symptom of AD and a contributing factor to cognitive impairment. Maintaining proper sleep can help prevent cognitive impairment, AD, and dementia. Sleep deprivation may increase the risk for beta-amyloid (Aβ) build-up and …

The Effect Of Verbal Encouragement With Swearing On High Intensity Exercise Performance, Ella Kern

Undergraduate Student Symposium

Verbal encouragement has not been shown to reliably enhance performance on the Wingate Anaerobic Test (WAnT); however, research has found that when individuals swear during the WAnT, average power increases. This study examined whether incorporating swearing into verbal encouragement during a WAnT enhances performance, self-confidence, and psychological flow compared to standard verbal encouragement without swearing. Forty-one physically active participants (25 females, 16 males; age 20.8 ± 0.78 years) completed two counterbalanced laboratory visits involving verbal encouragement with swearing (VES) and without swearing (VE) while performing the WAnT on a Wattbike Air ergometer. Average power, fatigue index, self-confidence, and psychological flow …

Uncovering Hidden Bioenergetic Effects Of Deet: Is Mitochondrial Complex I A Primary Target?, Jacob Kora, Dillen-Preetesh Patel

Undergraduate Student Symposium

DEET (N, N-diethyl-m-toluamide) is one of the most common insect repellents worldwide and is generally regarded as safe for humans. As such, DEET is available as a nonprescribed product to the public for topical application, with concentrations reaching up to 4.0M. However, new studies in other organisms suggest it may have a greater physiological effect than thought before. Research has shown that DEET can reduce Photosystem II activity in algae, alter red blood cell production and lipid metabolism in fish, and cause developmental and cardiovascular issues in zebrafish embryos. These findings point toward disruptions in mitochondrial and oxidative processes. Mammalian …
