Journal of Marine Science and Technology–Taiwan

This study investigates the controlling factors of carbon sequestration (CS) in seagrass bed sediments across three distinct environments in Taiwan: the Kenting (KT) coastal area, the Penghu (PH) open inner bay, and the Dongsha (DS) Atoll lagoon. Actual measurements of the substrate depth beneath the sediment and ground-penetrating radar (GPR) scans of the beach reveal that the coral reef bedrock in KT slopes landward. A field survey of the seagrass area in KT was conducted, and three cross-sectional profiles were analyzed to determine their topography, yielding a median sediment thickness of 88.2cm. Based on these measurements, the sediment volume was …

Calculation Of Aquifer Transmissivity From Borehole Resistance Measurements And Pumping Test Results, Fen-Rong Yang, Chien-Wei Huang, Tien-Kuen Huang

Journal of Marine Science and Technology–Taiwan

Transmissivity is a crucial hydrogeological parameter for evaluating groundwater resources. This parameter is conventionally evaluated using pumping tests; however, these tests are costly and can be conducted at few sites. Many researchers have used ground resistance and pumping test data to estimate various hydrogeological parameters. In this study, borehole resistance survey and pumping test data collected by the Taiwan Groundwater Monitoring Network were used to establish the relationship between transmissivity and formation factor for aquifers in the Zhuoshui River alluvial fan. This relationship was then used to estimate the water output of the aforementioned aquifers in a cost-effective manner from …

A Neural Network-Based Sliding Mode Adaptive Control System For Unmanned Surface Vehicles, Sun Qiaomei, An Liang, Jiang Linglin

Journal of Marine Science and Technology–Taiwan

Over the past decades, numerous studies have explored the use of autonomous unmanned surface vehicles (USVs). Successful USV operation requires a robust tracking control system to perform a range of tasks. However, USV dynamics are uncertain, time-varying, and nonlinear. This paper presents a neural network-based sliding mode adaptive control (NNSMAC) system to enhance USV tracking performance. Trajectories were generated using spline and polynomial interpolation based on a set of N predefined waypoints. Simulation results show that the proposed method outperforms traditional sliding mode control in error reduction, enabling more effective tracking.

Scaling Laws For Diffusion In Crystallized Plasma From Molecular Dynamics, Dany Yaacoub

Theses and Dissertations

Diffusion coefficients for crystallized Coulomb plasmas are essential microphysics input for modeling white dwarf cores and neutron star crusts. Solving for diffusion coefficients require running large molecular dynamics simulations with thousands of particles over millions of timesteps. The diffusion in a crystallized plasma has been largely ignored and is often taken to be zero in stellar evolution codes. We find that not only is this incorrect, but we find that the diffusion in a crystallized plasma can be modeled completely using a universal scaling law independent of screening. Our simulations also show that the dominant mode of diffusion in a …

Nutrient Transport And Transformation In Anaerobic Co-Digestion Of Crop Residues And Swine Manure, Shelby Stoner

Theses and Dissertations

Cover crops may improve soil quality, water quality, soil health, reduce soil fertilizer use, and increase nutrient availability to cash crops. The benefits of cover crops are discussed due to the below ground presence of cover crops, but the aboveground biomass can serve as a source of sustainable energy through anerobic digestion. The nutrients in the above ground biomass can also be recycled and reused through land application of digestion effluent. We have tested anaerobic co-digestion of different biomass feedstocks: cover crops, soybean stalk, and corn stover with swine manure using both small and pilot scale digesters. Nutrients, specifically NPK, …

How I Came To Understand What Art Was, Ilse Miller

Theses and Dissertations

This thesis explores my multidisciplinary art practice through three specific types of work: mobiles, books, and boxes. Each type of artwork functions as a vessel used to preserve objects and fleeting moments. Rooted in Anna Kornbluth's "aesthetic regime of immediacy," the work balances preservation with loss and intuition with craft. Inspired by Rauschenberg and Abercrombie, it challenges artistic boundaries by using immediate, everyday materials. These mobiles, books, and boxes become conduits for memory and invite viewers to connect personal and collective experiences.

The Development Of A One Pot, Two Reaction Synthetic Preparation Of 1,2,4-Oxadiazole, And Synthesis Of Ataluren, A Novel Drug In The Fight Against Duchenne Muscular Dystrophy. Efforts Towards The Synthesis Of A Potential Protease Inhibitor Against The Main Protease (3clpro) Of Covid-19, Austin J. Carter

Theses and Dissertations

1,2,4-Oxadiazoles are five-membered heterocyclic structures first synthesized by Tiemann and Krüger in 1884. Recent discoveries suggest an array of useful biological properties.In preparation of 1,2,4-oxadiazoles, the most prevalent precursors are amidoximes, which can be created via the reaction of nitriles with hydroxylamine hydrochloride and a base. The amidoximes are reacted with an activated carboxylic acid to yield an acylated intermediate. This intermediate can be exposed to a base to cyclize into the 1,2,4-oxadiazole. This thesis describes the efforts in combining these three steps into a unified one-pot synthesis.

Currently, there are a significant number of commercially available FDA approved and …

At The Mercy Of All Things: Nurturing Experimental Queer Writing On Embodied Mothering, Charley Koenig

Theses and Dissertations

This dissertation is an exploration of the ability of experimental queer writing to grow and transform expressions of mothering and care. The moves made here—both in the scholarship and anchor texts examined herein and in my own contributions to this effort—work to dethatch those toxic dominating narratives on motherhood, enforced and reinforced by our current Western society and culture, that contaminate and restrict our constructions of what it means to be and do mother. The collective work of experimental queer writers makes possible more nuanced, realistic, messy, complex, varied, embodied, liberating, and literally and figuratively dirty renditions of mothering and …

Cultural Identity In Mental Health Services And Helpseeking Behaviours Among African International Students, Mark Ofosu Asirifi

Theses and Dissertations

Acculturation stress impacts international students’ psychological well-being and academic success, yet research on African students remains limited. For African international students, this stress is intensified by cultural stigma surrounding mental health services, deterring help-seeking due to fears of judgment and ostracization. This identity negotiation complicates their willingness to access support, reinforcing cultural barriers to mental health care. This study explores how cultural identity shapes the mental health perceptions and help-seeking behaviors of African international students in the United States. Grounded in the Communication Theory of Identity (CTI) and the Health Belief Model (HBM), the research examines how acculturative stress, stigma, …

Listening To The Body: Attunement And Advocacy In Women's Experiences Of Endometriosis, Rebekah E. Greenslaugh

Theses and Dissertations

Endometriosis is a chronic, inflammatory condition in which tissue similar to the endometrial lining grows outside the uterus, leading to severe pain, fatigue, and other debilitating symptoms. Despite its significant impact on daily life, many women with endometriosis report that their symptoms are dismissed in medical encounters, as their pain is minimized or normalized as an inherent aspect of womanhood. This medical dismissal, combined with a lack of definitive diagnostic tools and effective treatments, leads many to turn to online support communities to make sense of their symptoms, share experiences, and develop ways to cope with the condition. Drawing on …

Natural aquatic systems are characterized by complex ecological processes and interactions occurring across multiple scales, and quantifying them is essential for proper management. However, managers often face decreasing budgets, increasing responsibilities, and limited staffing, resulting in challenges related to data prioritization, digitization, and management. While modern analytical technologies offer powerful tools, their effectiveness relies heavily on timely and accurate data input from diverse sources, including written, audio, and visual formats. Traditional data management practices are time-consuming, particularly due to the need for manual data verification. To address these challenges, innovative technologies leveraging artificial intelligence (AI)—including deep learning, machine learning, and …

The Role Of Sptbn1 Protein In Microglia Cells Actin Structure And Hiv-1 Infection, Rachel Pecka

Graduate Theses/Dissertations

Human immunodeficiency virus (HIV) directly attacks the host immune system by infecting and replicating in CD4-presenting immune cells. Like most viral pathogens, HIV utilizes cellular machinery to assist in viral entry, transport, and export. One of the components HIV is known to utilize for replication is the actin cytoskeleton. By directly binding to actin or actin-binding proteins, HIV can manipulate structural dynamics within the cell. The way HIV hijacks actin for replication post-viral fusion isn’t fully understood, especially during viral transport to the nucleus. A 2013 study conducted by Dai et al. found that lowering the expression of the cellular …

Civil Society And The Crisis Of Privacy Law, Ari Ezra Waldman

Emory Law Journal

Based on interviews with key players, public reports, and previously undisclosed primary sources, this Article tells the inside story of the American Data Privacy and Protection Act (ADPPA) and the role of privacy nonprofit organizations in crafting it. It uses ADPPA’s drafting as a case study about larger questions of expertise, the lawmaking process, and the role of law in setting the context of advocacy. The Article’s descriptive argument is that background law and the dynamics of privacy policymaking in the United States Congress channeled and constrained the choices made by privacy civil society organizations while negotiating and drafting key …

A Deep Look At Copyright’S Volitional Conduct Doctrine And Generative Artificial Intelligence, Aleksander J. Goranin

Emory Law Journal

This Article examines copyright’s volitional conduct doctrine, as applied to generative artificial intelligence (AI) systems. It traces the doctrine’s origins and evolution through key court decisions, analyzing its underlying rationale as a response to the harshness of the RAM copy rule and its elaboration as a proximate causation doctrine. The Article then evaluates how classic volitional conduct analogies to copy shops and photocopies may fit generative AI systems. Ultimately, the Article proposes a jury instruction to guide application of the volitional conduct doctrine in generative AI cases. The Article argues that the doctrine serves an important role in copyright law, …

Playing Politics: Social Media, Censorship, And Speech Gamification, Khaled A. Beydoun

Emory Law Journal

Forty percent of Americans self-censor their speech online. While staggering, the hidden phenomenon beneath this figure reveals a more dystopic outlook for the future of free speech. The powerful predictive technologies driving social media platforms, which the Supreme Court dubbed “the most important spaces for the exchange of views,” control the terms of modern speech and the scope of political discourse. The Supreme Court’s laissez-faire posture toward online speech moderation has only empowered digital dominion over modern expression and citizenship to the detriment of free speech principles.

As such, the primary threat to free speech today is not the state …

Molecular Mechanisms And Comparative Transcriptomics Of Diapause In Two Corn Rootworm Species (Diabrotica Spp.), Melise C. Lecheta, Chad Nielson, B. Wade French, Emily Nadeau, Nicholas M. Teets

Entomology Faculty Publications

Diapause is a programmed developmental arrest that can occur at any developmental stage depending on species, but the mechanisms that underscore embryonic diapause are poorly understood. Here, we identified molecular mechanisms underscoring distinct phases of diapause in the Diabrotica spp. complex. This species complex in- cludes economically significant agricultural pests, notably the western corn rootworm (WCR) and northern corn rootworm (NCR), which cause major losses in maize production. Rootworms undergo an obligate embryonic diapause to synchronize their life cycles with host plants, and we sequenced transcriptomes from both species at five time points (pre-diapause, diapause initiation, diapause maintenance, diapause termination, …

Collaborative Efforts To Combat Racism: Academics And Criminal Defense Lawyers In The Pursuit Of Racial Justice In California, Alvarez, Karina, Cameron-Wedding, Dr. Rita

Santa Clara Law Review

Lawyers and academics frequently cooperate to shape public policy and outcomes in specific cases, including in the area of racial justice. However, too frequently, lawyers and academics operate in silos—working towards the same goal of racial justice, but in different arenas. Lawyers are bound to their clients, foremost, and to advocacy before the court—often so much so that they might lose sight of broader challenges, achievements, and theories in racial justice. By contrast, academics spend their lives in the abstract, leaving them at risk of losing sight of the on-the-ground impact of their expert theoretical advances. This article aims to …

Conservative Family Values As Constitutional Law: Private Regulation And The Erosion Of Fundamental Rights, Spera, Clara, Fleming, Katherine

Santa Clara Law Review

This Article examines a paradox in contemporary constitutional law: While constitutional rights traditionally protect minorities against majority preferences, the Supreme Court has increasingly enabled certain private actors to override others’ constitutionally protected family formation choices through what this Article calls “private regulation.” The Court’s decisions allow individual private actors to impose traditional religious and moral views on others who do not share those beliefs, while simultaneously embedding those very views in constitutional jurisprudence. This dual approach creates a troubling inversion. Instead of constitutional rights serving their traditional function of protecting minorities from majority overreach, they are being used to empower …
