Characterization Of Aromatic Stationary Phases For Uses In High Performance Liquid Chromatography, Anastasia Davis

Honors Theses

High Performance Liquid Chromatography (HPLC) is an analytical chemist technique used to separate a sample into its components to characterize and study a specific molecule or compound. Traditionally, High-Performance Liquid Chromatography in different industries, such as the environmental and pharmaceutical fields, uses stationary phases that are already well characterized, such as the C18 stationary phase for separation. However, aromatic stationary phases have recently been produced, which have phenyl groups bonded to the interior surface of the column. Still, they have not been well characterized because of how modern they are. This project characterized several aromatic stationary phases (Biphenyl, pentafluorophenyl, and …

The multinational Africa-FINGERS program offers an innovative solution, pioneering culturally sensitive, multidomain interventions tailored to the unique challenges of the region. Leveraging insights from landmark global studies such as Worldwide-FINGERS and Alzheimer's Disease Neuroimaging Initiative, the program employs a multideterminant precision prevention framework, grounded in community based systems dynamics. Africa-FINGERS further integrates cutting-edge state-of-the-art multimodal biomarker …

Anti-Egfr Aptamer Exhibits Direct Anti-Cancer Effects In Nsclc Cells Harboring Egfr L858r Mutations, Brian J. Thomas, Sania Z. Awan, Trupti Joshi, Mark A. Daniels, David Porciani, Donald H. Burke

Biomedical Sciences

Non-small cell lung cancer (NSCLC) adenocarcinoma (LUAD) is a leading cause of death worldwide. Activating mutations in the tyrosine kinase domain of the oncogene epidermal growth factor receptor (EGFR) are responsible for ~10–50% of all LUAD cases. Although tyrosine kinase inhibitors (TKIs) have been effective in prolonging patient survival and quality of life, acquired resistance and disease progression are inevitable, presenting a clear unmet need for alternative or adjuvant therapeutics. Here we show that an anti-EGFR aptamer (EGFRapt) decreases viability and tumor growth of LUAD cell lines harboring the L858R ± T790M mutation in EGFR. Additionally, we elucidate …

Small And Long Non-Coding Rna Analysis For Humantrophoblast-Derived Extracellular Vesicles And Their Effect On The Transcriptome Profile Of Human Neural Progenitor Cells, Jessica A. Kinkade, Pallav Singh, Mohit Verma, Teka Khan, Toshihoko Ezashi, Nathan J. Bivens, R. Michael Roberts, Trupti Joshi, Cheryl S. Rosenfeld

Biomedical Sciences

In mice, the fetal brain is dependent upon the placenta for factors that guide its early development. This linkage between the two organs has given rise to the term, the placenta–brain axis. A similar interrelationship between the two organs may exist in humans. We hypothesize that extracellular vesicles (EVs) released from placental trophoblast (TB) cells transport small RNA and other informational biomolecules from the placenta to the brain where their contents have pleiotropic effects. Here, EVs were isolated from the medium in which human trophoblasts (TBs) had been differentiated in vitro from induced pluripotent stem cells (iPSC) and from cultured …

Multi-Step Ahead Water Level Forecasting Using Deep Neural Networks, Fahimeh Sharafkhani, Steven Corns, Robert Holmes

Engineering Management and Systems Engineering Faculty Research & Creative Works

Stream gauge height (water level) is a significant indicator for forecasting future floods. Flooding occurs when the water level exceeds the flood stage. Predicting imminent floods can save lives, protect infrastructure, and improve road traffic management and transportation. Deep neural networks have been increasingly used in this domain due to their predictive capabilities in capturing complex features and interdependencies. This study employs four distinct models—Multi-Layer Perceptron (MLP), Long Short-Term Memory (LSTM), transformer, and LSTNet—with MLP serving as the baseline model to forecast water levels. The models are trained using data from 20 distinct river gages across the state of Missouri …

Underrepresented Minority Faculty In The Usa Face A Double Standard In Promotion And Tenure Decisions, Theodore Masters-Waage, Christiane Spitzmueller, Ebenezer Edema-Sillo, Ally St. Aubin, Michelle Penn-Marshall, Erika Henderson, Peggy Lindner, Cynthia Werner, Tracey Rizzuto, Juan Madera

Engineering Management and Systems Engineering Faculty Research & Creative Works

Underrepresented minority (URM) faculty face challenges in many domains of academia, from university admissions to grant applications. We examine whether this translates to promotion and tenure (P&T) decisions. Data from five US universities on 1,571 faculty members' P&T decisions show that URM faculty received 7% more negative votes and were 44% less likely to receive unanimous votes from P&T committees. A double standard in how scholarly productivity is rewarded is also observed, with below-average h-indexes being judged more harshly for URM faculty than for non-URM faculty. This relationship is amplified for faculty with intersectional backgrounds, especially URM women. The differential …

Verifying Models Of The Underwater Soundscape From Wind And Ships With Benchmark Scenariosa), S Bruce Martin, Martin Siderius, Michael A. Ainslie, Michele B. Halvorsen, Leila Hatch, Mark K. Prior, Daniel Brooker, James Caplinger, Christine Erbe, John Gebbie, Multiple Additional Authors

Electrical and Computer Engineering Faculty Publications and Presentations

Models of the underwater acoustic soundscape are important for evaluating the effects of human generated sounds on marine life. The performance of models can be validated against measurements or verified against each other for consistency. A verification workshop was held to compare models that predict the soundscape from wind and vessels and estimate detection ranges for a submerged target. Eight modeling groups participated in the workshop which predicted sound levels with observation windows of 1 min and 1 km2. Substantial differences were found in how modelers computed the propagation losses for decidecade bands and estimated the source level of wind. …

If Lived Experience Could Speak: A Method For Repairing Epistemic Violence In Law And The Legal Academy, Terrell Carter, Rachel Lopez

Minnesota Law Review Vols. 106:2 onward (2021-present)

Terrell Carter grew up only a stone’s throw from Drexel University, the institution of higher learning where the other coauthor of this Article, Rachel López, would find her academic home years later. Even as a child, Terrell remembers feeling like other institutions that were miles away, like State Correctional Institution Graterford where he would spend most of his adult life, were much more proximate. Paradoxically, he would later come to learn that behind the walls of institutions like Drexel, academics like Rachel would develop ideas and theory that would shape his fate and define his existence behind other walls. Through …

Teaching Statistics For The Social Sciences Using Active Learning: A Case Study, Daniel Douglas

Department of Sociology Faculty Scholarship and Creative Works

US college students are typically required to take at least one mathematics or statistics course, either as part their major area of study, or as a general education requirement. College mathematics requirements are an obstacle for many college students. Active learning, a pedagogical approach that places emphasis on students’ collaborative work, has been shown to increase student learning and course success in STEM fields of study and in mathematics courses. Active learning has also been shown to be adaptable to courses involving computer software and programming, such as introductory statistics. This case study is based on the author’s experience implementing …

Balanced Index Sets Of Graphs And Semigraphs, Nagarjun Prabhu, Devadas Nayak

Open Access archive

Let G be a simple graph with vertex set V (G) and edge set E(G). Graph labeling is an assignment of integers to the vertices or the edges, or both, subject to certain conditions. For a graph G(V, E), a friendly labeling f : V (G) → {0, 1} is a binary mapping such that |vf(1) − vf(0)| ≤ 1, where vf(1) and vf(0) represents number of vertices labeled by 1 and 0 respectively. A partial edge labeling f^∗ of G is a labeling of edges such that, an edge uv ∈ E(G) is, f^∗(uv) = 0 …

In-Silico Study On Cumulative Effects Of Degeneration And Anterior Circumferential Annular Tear On The L5-S1 Spinal Unit, Vinyas, Subraya Krishna Bhat, Hiroshi Yamada, N. Shyamasunder Bhat

Open Access archive

Low back pain is a serious health concern prevalent in majority of the people around the world, especially in case of the elderly. The root cause for this is mostly observed to be the development of lesions/ tears complemented by degenerative effects in the intervertebral disc of L4-L5 and L5-S1 segments. This study aims to analyse the effects of disc degeneration and tears on the mechanical responses of the L5-S1 spinal unit, which has not been investigated. The annulus is represented by an anisotropic hyperelastic Gasser-Ogden-Holzapfel (GOH) model wherein the effect of degeneration is defined by varying the constants responsible …

Is The Population Of The Critically Endangered White-Bellied Heron Declining In Namdapha Tiger Reserve, India?, Rohan K. Menzies, Kulbhushansingh R. Surya Wanshi, Rohit Naniwadekar

Open Access archive

The Critically Endangered white-bellied heron Ardea insignis is a large-bodied, range-restricted, piscivorous bird of the Himalayan mountains. With fewer than 60 individuals remaining globally, regular monitoring is required for this rare species. We present the results of surveys during 2017 and 2023-2024 in Namdapha Tiger Reserve, Arunachal Pradesh, India. The encounter rate of white-bellied herons in 2017 was 0.55 individuals per km of river, but we did not detect the bird during intensive surveys in the same location during 2023-2024. The surveyed area within the Reserve was once a stronghold for the species, but its population appears to be declining. …

Genealogy In Constitutional Law, Charles W. Tyler

Vanderbilt Law Review

Genealogy is a form of argument that seeks to discredit social phenomena by exposing their pernicious ancestry. In recent years, the U.S. Supreme Court has used genealogy to undermine key provisions of written law, doctrinal rules, longstanding practices, and private conduct in cases involving a wide range of constitutional issues.

After comprehensively documenting this development, this Article contends that genealogy can advance conclusions within several widely recognized modalities of constitutional interpretation. More specifically, genealogy can be used to undermine assertions of authority implicit in arguments from precedent, tradition, and ethos. And it can be used to reveal its object’s function …

The Effects Of Antitrust Laws On Horizontal Mergers: International Evidence, Chune Young Chung, Iftekhar Hasan, Jihoon Hwang, Incheol Kim

Finance Faculty Publications

This study examines how antitrust law adoptions affect horizontal merger and acquisition (M&A) outcomes. Using the staggered introduction of competition laws in 20 countries, we find antitrust regulation decreases acquirers’ five-day cumulative abnormal returns surrounding horizontal merger announcements. A decrease in deal value, target book assets, and industry peers' announcement returns are consistent with the market power hypothesis. Exploiting antitrust law adoptions addresses a downward bias to an estimated effect of antitrust enforcement (Baker (2003)). The potential bias from heterogeneous treatment effects does not nullify our results. Overall, antitrust policies seem to deter post-merger monopolistic gains, potentially improving customer welfare.
