Branch Mathematics and Statistics Faculty and Staff Publications

Graph Neural Networks (GNNs) have emerged as a powerful tool for node representation learning within graph structures. However, designing a robust GNN architecture for node classification remains a challenge. This study introduces an efficient and straightforward Residual Attention Augmentation GNN (RAA-GNN) model, which incorporates an attention mechanism with skip connections to discerningly weigh node features and overcome the over-smoothing problem of GNNs. Additionally, a novel MixUp data augmentation method was developed to improve model training. The proposed approach was rigorously evaluated on various node classification benchmarks, encompassing both social and citation networks. The proposed method outperformed state-of-the-art techniques by achieving …

A Reconsideration Of Advanced Concepts In Neutrosophic Graphs: Smart, Zero Divisor, Layered, Weak, Semi, And Chemical Graphs, Takaaki Fujita, Florentin Smarandache

Branch Mathematics and Statistics Faculty and Staff Publications

One of the most powerful tools in graph theory is the classification of graphs into distinct classes based on shared properties or structural features. Over time, many graph classes have been introduced, each aimed at capturing specific behaviors or characteristics of a graph. Neutrosophic Set Theory, a method for handling uncertainty, extends fuzzy logic by incorporating degrees of truth, indeterminacy, and falsity. Building on this framework, Neutrosophic Graphs [9,84,135] have emerged as significant generalizations of fuzzy graphs. In this paper, we extend several classes of fuzzy graphs to Neutrosophic graphs and analyze their properties.

Three Novel Approaches To Deep Space: Interstellar Travel That Transcend The Limitations Imposed By The Rocket Equation, Victor Christianto, Florentin Smarandache

Branch Mathematics and Statistics Faculty and Staff Publications

At the time of writing this abstract, we read about Betelgeuse star has exploded in the last few days. While there are various explanations and interpretations on how that event would have impacted this Earth’s inhabitants, our interpretation asserts that there are several chains of stars that act to lock this Earth to the 3D realm, and the exploded Betelgeuse star can be considered as a signal from heaven that we, all Earth inhabitants, are allowed to be elevated to 5D consciousness and to explore the Deep Space beyond this solar system. Therefore, in the present paper, it is considered …

A Right-Brain-Based Epistemology Grounded On Local Wisdom: Intuilytics As A Culturally-Meaningful Alternative In Science, Victor Christianto, Florentin Smarandache

Branch Mathematics and Statistics Faculty and Staff Publications

Epistemology, the study of knowledge, has long grappled with the challenge of determining truth. While the combination of deductive and inductive reasoning has been a cornerstone of scientific inquiry, several limitations emerge in its application to contemporary epistemology. One significant issue lies within the core of falsificationism, a prominent philosophy championed by Karl Popper. Falsificationism posits that a scientific theory can only be proven false, not true. While this approach aims to prevent dogmatic adherence to untested ideas, it can lead to an endless cycle of trial and error. As Popper himself acknowledged, no single experiment can definitively prove a …

Abmscore: A Heuristic Algorithm For Forming Strategic Coalitions In Agent-Based Simulation, Andrew J. Collins, Gayane Grigoryan

Engineering Management & Systems Engineering Faculty Publications

Integrating human behavior into agent-based models has been challenging due to its diversity. An example is strategic coalition formation, which occurs when an individual decides to collaborate with others because it strategically benefits them, thereby increasing the expected utility of the situation. An algorithm called ABMSCORE was developed to help model strategic coalition formation in agent-based models. The ABMSCORE algorithm employs hedonic games from cooperative game theory and has been applied to various situations, including refugee egress and smallholder farming cooperatives. This paper discusses ABMSCORE, including its mechanism, requirements, limitations, and application. To demonstrate the potential of ABMSCORE, a new …

Can Multi-Species Plantings Alleviate Abiotic Stressors To Enhance Bald Cypress Restoration?, Victoria S. Ellis, Taylor M. Sloey

Biological Sciences Faculty Publications

Restoration researchers and practitioners alike advocate for novel restoration approaches, informed by ecological theories and principles, to enhance the likelihood of meeting restoration goals. Forested wetland restoration has historically focused on creating abiotic conditions that support the tolerance thresholds of desired species, but the stress gradient hypothesis provides guidance for potential new strategies that use biotic interactions to ameliorate stressful abiotic conditions. In this study, we tested whether multi-species planting approaches can be used to enhance the survival and growth of a target restoration tree species, Bald cypress, along multiple abiotic gradients. We conducted a fully factorial controlled greenhouse experiment …

Jennerjahn, C. E. Lovelock, D. Friess, G. M. S. Reithmaier, C. A. Buelow, S. M. Muhammad-Nor, R. R. Twilley, R. A. Ribeiro

Biological Sciences Faculty Publications

Mangroves are one of the most carbon-dense forests on the Earth and have been highlighted as key ecosystems for climate change mitigation and adaptation. Hundreds of studies have investigated how mangroves fix, transform, store, and export carbon. Here, we review and synthesize the previously known and emerging carbon pathways in mangroves, including gains (woody biomass accumulation, deadwood accumulation, soil carbon sequestration, root and litterfall production), transformations (food web transfer through herbivory, decomposition), and losses (respiration as CO₂ and CH₄, litterfall export, particulate and dissolved carbon export). We then review the technologies available to measure carbon fluxes in …

The Flesh And Silicon Mesh: A New Materialist Conception Of Advanced Digital Machines, Joshua Nieubuurt

English Faculty Publications

Digital machines, including artificial intelligence (AI), have long been held as potential agents of social change. From their binary role in cultural productions to the real-world implementation of such, digital machines have typically been considered within the Heideggerian “readiness-to-hand” category of Being. This paper seeks to alter conceptually this dynamic through the use of new materialism and Morton’s concept of the “mesh” to provide a new understanding of the social and pragmatic roles advanced digital machines play in ecologies in which they dwell and continue to emerge. Through briefly tracing the complex intermingling of advanced digital machines in the realms …

Cypher, Ed Osborn, Eduardo Turcios Valle, Jacob L. Gregg, Paul K. Hershberger, Yuri Kurerov, Sarah King, Aleksandar I. Goranov, Patrick G. Hatcher, Anastasia Konefal, T. Erin Cox, Justin B. Greer, James P. Meador, Matthew A. Tarr, Patrick L. Tomco, David C. Podgorski

Chemistry & Biochemistry Faculty Publications

Crude oil toxicity to early life stage fish is commonly attributed to polycyclic aromatic hydrocarbons (PAHs). However, it remains unclear how the polar unresolved complex mixture (UCM), which constitutes the bulk of the water-soluble fraction of crude oil, contributes to crude oil toxicity. Additionally, the role of photomodification-induced toxicity in relation to the polar UCM is not well understood. This study addresses these knowledge gaps by assessing the toxicity of two laboratory generated polar UCMs from Cook Inlet crude oil, representing the readily water-soluble fraction of crude oil and photoproduced hydrocarbon oxidation products (HOPs), to Pacific herring (Clupea pallasii …

Introduction: Autoimmunities In The Wake Of Covid-19, Travis Alexander, Nishant Shahani

English Faculty Publications

Our introduction and the essays collected in this Special Section address themselves to the ruins, creations, and legacies of the ongoing COVID-19 pandemic. More precisely, we ask how our notions of immunity and especially autoimmunity have changed over the last three years. We theorize autoimmunity in the wake of COVID-19 through approaches that consider the material and experiential phenomenology proliferated by the longue durée of both the experience of COVID-19 infection and the pandemic itself. In this way, we connect our inquiries both to the history of recent epidemics—most notably HIV/AIDS—and to broader philosophical and cultural investigations of what immunity …

The OTTC consisted of training modules covering topics including tick biology, tick identification, tick-borne diseases, and public health, personal tick …

Active Facilitation Of Helper Dispersal By Parents And Siblings In The Cooperatively Breeding Acorn Woodpecker, Natasha D. G. Hagemeyer, Walter D. Koenig, Eric L. Walters

Biological Sciences Faculty Publications

Offspring that delay dispersal in cooperatively breeding species have been hypothesized to gain direct fitness benefits via parental facilitation—being passively tolerated on their natal territory by their parents—thereby enjoying enhanced survival and increased probability of acquiring a breeding position in the population. Here we describe active facilitation in the acorn woodpecker (Melanerpes formicivorus) by parents and siblings assisting the dispersal of helpers in their social group. Helpers in this species compete for reproductive opportunities in “power struggles” that take place when all breeders of one sex die or disappear, creating a reproductive vacancy. Individuals compete at power struggles …

Baby's First Jets: A Kinematic And Hydrodynamic Analysis Of Turning In Cuttlefish Hatchlings, Alissa M. Ganley, Paul S. Krueger, Ian K. Bartol

Biological Sciences Faculty Publications

Turning is an important aspect of life underwater, playing integral roles in predator avoidance, prey capture, and communication. While turning abilities have been explored in a diversity of adult nekton, little is currently known about turning in early ontogeny, especially for cephalopods. In this study, we investigated the turning abilities of hatchling common cuttlefish (Sepia officinalis, n = 49) and dwarf cuttlefish (Sepia bandensis, n = 30), using both kinematic and wake-based analyses. Using body tracking software and particle image velocimetry (PIV), we found that S. officinalis turned faster than S. bandensis, but both species …

Two species of Psychotria have been recognised in the Galapagos Islands, both understorey shrubs endemic to the archipelago: P. rufipes Hook.f. occurs on seven islands, including Floreana, while P. angustata Andersson is endemic to Floreana. Since their mid-19th century discovery, the taxonomic and ecological status of these species has been uncertain. To clarify this, we examined historical specimens and numerous recent collections of both species, and …

Role Of Nitrogenous Functional Group Identity In Accelerating 1,2,3- Trichloropropane Degradation By Pyrogenic Carbonaceous Matter (Pcm) And Sulfide Using Pcm-Like Polymers, Han Cao, Jingdong Mao, Paul G. Tratnyek, Wenqing Xu

Chemistry & Biochemistry Faculty Publications

Groundwater contamination by 1,2,3-trichloropropane (TCP) poses a unique challenge due to its human toxicity and recalcitrance to degradation. Previous work suggests that nitrogenous functional groups of pyrogenic carbonaceous matter (PCM), such as biochar, are important in accelerating contaminant dechlorination by sulfide. However, the reaction mechanism is unclear due, in part, to PCM's structural complexity. Herein, PCM-like polymers (PLPs) with controlled placement of nitrogenous functional groups [i.e., quaternary ammonium (QA), pyridine, and pyridinium cations (py⁺)] were employed as model systems to investigate PCM-enhanced TCP degradation by sulfide. Our results suggest that both PLP-QA and PLP-py⁺ were highly effective …

Type-B Energetic Processes: Their Identification And Implications, James Weifu Lee

Chemistry & Biochemistry Faculty Publications

We have now identified two thermodynamically distinct types (A and B) of energetic processes naturally occurring on Earth. Type-A energy processes, such as classical heat engines, apparently well follow the second law of thermodynamics; Type-B energy processes, such as the newly discovered thermotrophic function that isothermally utilizes environmental heat energy to perform useful work in driving ATP synthesis, follow the first law of thermodynamics (conservation of mass and energy) but do not have to be constrained by the second law, owing to their special asymmetric functions. Several Type-B energy processes such as asymmetric function-gated isothermal electricity production and epicatalysis have …

Advancements In The Synthesis Of Polyoxygenated Oxepanes And Thiepanes For Applications To Natural Products, Aditya R. Pote, Shayne M. Weierbach, Mark W. Peczuh, Kyle M. Lambert

Chemistry & Biochemistry Faculty Publications

Oxepanes are central motifs and tenants of many biologically important molecules, and their synthetic construction often presents a challenge to chemists due to consequential entropic and enthalpic barriers that have limited the synthetic toolbox to access these seven-membered oxacycles. This review covers the breadth of synthetic methods to afford the oxepane/thiepane moiety, with a focus on polyoxygenated oxepanes and includes radical cyclizations, Lewis acid-mediated cyclizations, ring closing-metathesis, Nicholas-Ferrier rearrangement, homologations, and ring-expansion strategies. Implementation of these tactics towards sugar-based and non-sugar based (de novo) approaches is presented alongside their extensive application to the total synthesis of several complex polyoxygenated oxepane-containing …

School Experiences Of Young Adults Since The Passing Of "Don't Say Gay", Heather M. Summers

Graduate Thesis and Dissertation post-2024

As of 2020, the US is home to an estimated over nine percent of youth 13-17 who identify as LGBTQ+ (Conron, 2020). There are hundreds of bills that have been passed into laws that restrict rights for LGBTQ+ individuals (Union, Mapping attacks on LGBTQ rights in US state legislatures in 2024, 2024). With risk factors specific to youth and with legislation altering the operation of schools, there is concern regarding the effect of such laws on students (Day, 2019). This dissertation provides an overview of how LGBTQ+ youth in schools have experienced the implementation of laws that emerged between 2022 …

Arousal Patterns, Fungal Loads, And Wing Damage In A Surviving Population Of Little Brown Bats (Myotis Lucifugus), Brooke A. Daly

Master's Theses and Doctoral Dissertations

Little brown bats (Myotis lucifugus) at Tippy Dam in Michigan have shown resilience to white-nose syndrome (WNS), which is caused by the fungus Pseudogymnoascus destructans. This study evaluated the impact of environment (temperature and moisture), pathogen virulence, and host susceptibility on survival. Host response was assessed using temperature-sensitive radio transmitters (n = 37) and ultraviolet photography (n = 57), while fungal load (n = 56) was evaluated through quantitative polymerase chain reaction (qPCR). High autumn temperatures (>10°C) favored growth of the fungus, while mid-hibernation temperature (3.2°C) was unfavorable. The mean torpor bout length (TBL) …

Structural Sex Discrimination: Why Gynecology Patients Suffer Avoidable Injuries And What The Law Can Do About It, Christopher T. Robertson, Annabel Kupke, Louise P. King

Emory Law Journal

Nearly four million Americans undergo gynecological surgeries each year, but these procedures are unnecessarily risky, as many suffer avoidable lifelong, painful, and disabling injuries. This Article diagnoses the root cause in our legal framework for healthcare finance. It then identifies solutions.

America’s public–private system for reimbursing healthcare pays for procedures rather than outcomes, and it pays substantially more for work on male rather than female anatomies. This disparity is due to the federal government’s reliance on a secretive industry committee to set those rates, and the committee’s reliance on junk science surveys, allowing self-interested and gender-biased responses, contrary to objective …

Impact Of Nursing Education On Kangaroo Mother Care: Neurodevelopment Outcomes In Preterm Infants, Giana Usac

Nursing | Student Research Posters

Preterm birth poses a significant risk to the normal trajectory of brain development, particularly in the cortex, which is responsible for higher cognitive functions, motor control, and socio-emotional processing. However, Kangaroo Mother Care (KMC) has emerged as an important early intervention capable of improving neurodevelopmental outcomes in preterm newborns. This quantitative research proposal aims to assess the influence of nurse education on KMC practices, identifying pivotal periods in infancy when KMC has the most significant impact on neurodevelopment outcomes in preterm infants. The literature critique focuses on the efficacy of nursing education, the optimization of KMC regarding duration and frequency, …

Multi-Parent Custody, Jessica Feinberg

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

In recent years, a number of jurisdictions have enacted laws recognizing that a child may have more than two legal parents (multi-parentage). Recognition of multi-parentage represents a significant change to the legal framework governing parentage— for most of U.S. history, it was well established that a child could have a maximum of two legal parents. While commentators undoubtedly will continue to debate the wisdom of multi-parentage recognition, it is clear both that multi-parentage has arrived and that its arrival raises many novel and important questions across a variety of areas of the law. Proponents and opponents of multi-parentage agree that …

Expansion And Ineffectiveness: The Evolution Of The Mexican Healthcare System, Leslie Bejaran Solorio

History and Political Science | Senior Theses

In the 1917 Mexican Constitution, Article 123 Section Number 14, health became an occupational right in which the employer paid for sickness and injuries, a right advocated in the Mexican Revolution. Despite this, it was not until 1943, with the creation of Instituto Mexicano del Seguro Social (Mexican Social Security Institute), that it became a reality. Following the creation of social security, other programs were established for federal workers (the Institute for Social Security and Services for State Workers), oil workers (Mexican Petroleum Company), and the armed forces (Ministry of National Defense and Secretariat of the Navy). Even then, the …

Tragedy To Transformation: The Ongoing Impact Of September 11th In The United States, Alison Mcneal

History and Political Science | Senior Theses

On September 11, 2001 (9/11), a coordinated Islamist terrorist attack hit the United States, consisting of four commercial airline hijackings and suicide attacks by 19 militants associated with the Islamic extremist group, Al-Qaeda. This paper identifies the significant and enduring influences of 9/11 on the United States including discrimination against people of Middle Eastern descent following the attack, a connection between the events of 9/11 and the enhanced interrogation techniques at the Abu Ghraib prison, and a surge in patriotism characterized by a sense of public solidarity and a notable rise in military enlistment in the Armed Forces. Through an …
