Acid-Base Regulation Mechanisms In The West African Lungfish Protopterus Annectens: An Investigation Into The Role Of The Sodium Proton Exchanger (Nhe), Victor H. Q. Pham-Ho Msc

Theses and Dissertations (Comprehensive)

The lungfish possesses a primitive lung and underdeveloped gills, making use of bimodal respiration. Like other freshwater fishes they must regulate ion- and acid-base equilibrium through active ion uptake (driven by pumps and ion transporters), albeit with challenges due to their underdeveloped gills. My thesis aimed to elucidate the role of the sodium proton exchangers (NHE), encoded by the genes slc9a1/nhe1, slc9a2/nhe2 and slc9a3/nhe3, which are hypothesized to contribute towards acid-base regulation. Pharmacologically, amiloride, a sodium-transport inhibitor, and 5-(N-Ethyl N-isopropyl)-Amiloride (EIPA), an NHE specific inhibitor, affected whole-animal titratable acidity and ammonia fluxes, supporting a physiological function of the NHE. Next, …

Mixed Methods Insights Into Understandings Of And Stigma Towards Autism In Children And Young Adults, Natalia Gc Van Esch

Theses and Dissertations (Comprehensive)

BACKGROUND: Autism is widely stigmatized and misunderstood. Existing research using methods such as questionnaires finds that autistic individuals are often evaluated more negatively than their non-autistic counterparts. Unfortunately, this approach provides limited insight into the underlying representations of autism that individuals hold. The present study seeks to examine how children and adults define, describe, and represent autism, and how these representations relate to stigma. METHODS: In Part I, children participated in a semi-structured interview in which they defined autism and created autistic and non-autistic characters using a guided character-building task. Children then rated their characters on a series of social …

Evops: Evolutionary Patch Selection In The Embedding Space Of Whole Slide Images, Saya Hashemian

Theses and Dissertations (Comprehensive)

Computational pathology increasingly relies on the analysis of Whole-Slide Images (WSIs), which capture tissue specimens at gigapixel resolution. Because a single slide is far too large to process directly, the

prevailing paradigm decomposes each WSI into thousands of small patches and encodes them as high- dimensional feature embeddings using deep learning backbones. While effective, this paradigm carries a

substantial cost: the resulting collections of patch embeddings are computationally expensive to store and process, and they are frequently dominated by redundant, homogeneous, or otherwise uninformative tissue regions that dilute the diagnostic signal. Existing patch selection methods largely depend on heuristic or …

Theoretical Study Of Long-Range Molecular Interactions, Adrian Luis Batista-Planas

Doctoral Dissertations

Describing intermolecular forces is fundamental to modeling and predicting the behavior of molecular systems. In particular, long-range molecular interactions—with electrostatic, induction, and dispersion as main components—play a critical role, especially for low-temperature and low-density regimes. Long-range interactions are often described through perturbation theory, representing the electronic charge distribution via multipolar series of the moments and polarizability tensors corresponding to each molecule. However, while the theory is well-established, obtaining the resulting analytical expressions (and their practical implementation) constitutes a highly complex and system-dependent task. To address this challenge, we developed Long-Range-Fit (LRF), an interactive and user-friendly software package designed to automate …

Critical Parameters Controlling Oxide Scale Formation And Hydro-Descaling Efficiency During Steelmaking, Tochukwu Princewill Ojiako

Doctoral Dissertations

In modern steelmaking, cast slabs are exposed to high-temperature oxidizing environments during secondary cooling, reheating, and hot rolling, resulting in the formation of multilayer oxide scales on the steel surface. These scales interact with mold-flux residues originating from the casting process (CC). The morphology, chemistry, and adhesion of oxide scale strongly influence its removability during high-pressure hydraulic descaling and ultimately determine the surface quality of hot-rolled products. However, the mechanistic relationship between oxide scale evolution, scale-steel interfacial structure, and hydraulic descaling performance remains poorly understood.

This dissertation investigates oxide scale formation, modification, and removal in low-carbon thin-slab steels produced by …

Security And Energy-Efficiency In Federated Learning, Priyesh Ranjan

Doctoral Dissertations

Federated Learning (FL), which facilitates collaborative model training and protects users' privacy, has drawn great interest from the research community. With FL, the participants train their models on local data and submit the corresponding updates for aggregation to a server. While concealing the participants' identities, FL may attract adversaries aiming to hamper the underlying model. These adversaries aim to submit malicious weight updates that corrupt the performance of the server model. Further, these models when communicated to the participating clients extend the behavior which is undesirable. Additionally, FL suffers from increased energy consumption at the edge device level due to …

Trust-Aware Algorithms For Stackelberg Ground Vehicle Routing, Doris Evelyn Meredith Brown

Doctoral Dissertations

Despite decades of research focused on reducing ground vehicle traffic congestion, urban traffic networks worldwide continue to experience traffic flows that lead to increased network travel times, largely resulting from the routing decisions of individual vehicles. To address this challenge, this work leverages a Stackelberg game framework to model the interaction between a vehicle agent and a routing authority as a leader–follower game, in which the routing authority proposes routing interventions to which the agent responds. This research contributes to existing traffic mitigation literature by exploring the role of trust in route decision-making and providing trust-aware algorithms that influence vehicle …

An Energy-Stable Mixed Cg-Dg Scheme For A Full Shliomis Phase Field Model Of Two-Phase Ferrofluid Flows, Mahdi Gharehbaygloo

Doctoral Dissertations

"Ferrofluids are magnetic nanoparticle suspensions whose motion couples surface tension, flow field, magnetostatics, and magnetization dynamics. This dissertation develops, analyzes, and validates an energy-stable finite element method for a two-phase ferrofluid model that couples the Cahn-Hilliard equations with the full Shliomis model of single-phase ferrofluids, retaining its damping torque term, magnetic torque term, and magnetic stress term.

The spatial discretization is a mixed continuous Galerkin (CG) and discontinuous Galerkin (DG) formulation. It uses continuous ��2 elements for the phase field, chemical potential, velocity, and magnetostatic potential, discontinuous ��2 elements for the magnetization, and discontinuous ��1 elements for the pressure. The …

Stall Detection In Hydraulic Excavator Operations Using Heuristics And Machine Learning: A Case Study, Mateo Fernando Montenegro Defaz, Kwame Awuah-Offei, Yixiang Gao

Mining Engineering Faculty Research & Creative Works

This work aims to develop a reliable algorithm for stall detection during excavator digging by analyzing key operational variables such as velocity and angular displacements from machine monitoring data. The work develops and validates a heuristic algorithm to detect stalling events and trains a support vector machine classification algorithm to distinguish between "normal" digging cycles and cycles with stalling. This work is a novel attempt at using a classification algorithm to categorize digging cycles into normal and those with stalling events based on machine monitoring data alone. The developed classification algorithm achieved a sensitivity of 100%, indicating it correctly identified …

Independent Animal Chiropractic Practice: An Evidence-Based Argument For Autonomy Beyond Veterinary Supervision, Montana Adams

Undergraduate Honors Theses

Animal chiropractic is a growing form of conservative care used to improve mobility, reduce pain, and support neuromusculoskeletal function in animals. Despite evidence suggesting it is both effective and low risk, access remains limited due to inconsistent state regulations. Many jurisdictions require chiropractors to obtain veterinary supervision, referral, or licensure, even when they have completed specialized training and certification in animal chiropractic. This paper evaluates the effectiveness and safety of animal chiropractic while analyzing the impact of current regulatory policies. Research indicates that chiropractic care can improve mobility and reduce spinal conditions in animals when performed by trained professionals. However, …

Due Process And Press Credentialing, Nicole J. Ligon

Scholarly Works

Government-issued press credentials increasingly determine which journalists may access public officials, attend government events, and report from restricted spaces. Yet the legal frameworks governing these credentials remain underdeveloped, discretionary, and structurally vulnerable to abuse. This Article examines the constitutional dimensions of press credentialing through the lens of procedural due process. It is the first law review article to consider whether press credentials give rise to protected liberty or property interests under the Fifth and Fourteenth Amendments, such that denial or revocation requires due process.

Drawing on analogies to professional licensing regimes and recent litigation involving credentialing disputes, this Article maps …

The Lithic Assemblage From The 700,000 Year-Old Butchery Site Of Kalinga (Luzon Island, Philippines): New Insights Into Technological Variability In The Early Palaeolithic In Island Southeast Asia, Alfred F. Pawlik, Justin Guilbert, Jean-Baptiste Lambard, Gerald Palaya, Jackie Despriee, Xavier Gallet, John De Vos, Andrea Dominique Cosalan, Maria G. Chacon

Archaeology

Despite a long history of archaeological and paleoanthropological research, our understanding of the Early Palaeolithic in Island Southeast Asia remains limited, as only a few sites with clear stratigraphic contexts - Mata Menge (Flores Island), Ngebung 2 (Java Island), Calio and Talepu (Sulawesi Island) - have been documented. This scarcity of well-stratified assemblages has led to a poor characterisation of technological variability and cultural sequences, which mainly rely on surface collections and early typological classifications/facies (e.g., Pacitanian, Cabengian, Cabalwanian, Liwanian, Arubian, etc). These classifications mostly based on a handful of cobble artefacts, have long obscured the technological diversity of early …

Altered Natural Killer Cell Function In Children With Severe Malaria, Grace Turyasingura, Kagan A. Mellencamp, Ruth Namazzi, Robert Opoka, Chandy C. John, Geoffrey T. Hart

Paediatrics and Child Health, East Africa

Memory-like natural killer (NK) cells with enhanced antibody-dependent cellular cytotoxicity (ADCC) have correlated with protection from uncomplicated malaria in prior studies. However, the role of NK cells in severe malaria (SM) has not been characterized. In Ugandan sites with moderate and low malaria transmission, we evaluated NK cell (CD56bright, CD56dim, CD56neg) phenotype and ADCC function by flow cytometry in children < 5 years of age with SM (n = 21) and control community children (CC, n = 19). Children with SM had similar total NK cell counts to CC. Children with SM had a higher proportion of LILRB1+ NK cells than CC. The level of malaria transmission …

Criminal Data Function Creep, Sarah E. Lageson

Journal of Criminal Law and Criminology

Automated, data-driven decision-making can create unfair outcomes and lead to discrimination. This Article considers a relatively ubiquitous part of modern life that is increasingly automated: the criminal background check. This Article, with contributions at the intersection of law and technology, antidiscrimination and consumer protection law, and sociological theory, makes the central claim that criminal record data is characterized by function creep—the unintended use of data for another purpose—which leads to a specific set of harms. This Article makes three central contributions. First, it offers an empirical assessment of contemporary, data-driven background screening using data based on in-depth interviews and systematic …

Rebutting The Presumption: A Constitutional Theory Of Pre-Trial Asset Seizures And Procedural Due Process, Benjamin Y. Rabin

Journal of Criminal Law and Criminology

In this Comment, I trace the origins and examine the current state of the doctrine on pre-trial asset seizures, then argue for a new approach grounded in procedural due process and constitutional theory.

The existing frameworks for assessing due process in these cases fall into three categories. The first grants the government broad presumptive validity for pre-trial seizures. The second applies a utilitarian balancing test, following the Supreme Court’s reasoning in Mathews v. Eldridge and Connecticut v. Doehr. The third, illustrated by the recent decision in Culley v. Marshall, relies on comparisons to historical practice.

I argue that …

Coercion, Trauma, And Grief In The Interrogation Room: Documenting And Analyzing Cases Of False Confessions To Murder Of A Family Member, Steven A. Drizin, Richard A. Leo, Hayley M. D. Cleary, Samara Hoose

Journal of Criminal Law and Criminology

This article examines the phenomenon of false confessions in cases in which individuals were falsely accused of murdering close family members. Drawing on a dataset of twenty-two proven false confession cases, we document how grief, trauma, and coercive interrogation practices intersect to produce highly counterintuitive admissions and narratives of guilt. The study situates these cases within the broader literature on police interrogation and false confessions, highlighting situational risk factors such as lengthy custodial interrogation, sleep deprivation, false evidence ploys, and threats and promises, alongside dispositional vulnerabilities such as youth, mental illness, and trauma exposure. Unlike prior aggregated studies of proven …

Eagle Eyes: How The Chicago Police Department’S Video Surveillance Network Is Used To Fight Crime And Its Fourth Amendment Implications, Joseph Mcinerney

Journal of Criminal Law and Criminology

Chicago, Illinois, is home to over 2.7 million individuals living under the supervision of a vast network of over forty thousand cameras integrated into a network of advanced technology run by the Chicago Office of Emergency Management. With little transparency, the City of Chicago has spent hundreds of millions of dollars in the past two decades rapidly expanding the network throughout the city while incorporating new technologies each year, posing substantial privacy risks for the millions of residents unaware of the ever-present eyes on them. To determine whether the network violates the Fourth Amendment, particularly in the wake of Carpenter …

Police Reform As System Justification, Shawn E. Fields

Journal of Criminal Law and Criminology

System Justification Theory (SJT) provides a useful lens through which to critique recent police reform efforts. SJT posits that members of society tend to justify and maintain existing social and political systems even when those systems disadvantage them, because the predictability of the status quo provides palliative, epistemic, and existential comfort in what otherwise appears to be an unjust and inequitable societal structure. Contrary to “false consciousness” theories, SJT claims that disadvantaged groups may intentionally rationalize what they know to be an unfair status quo, because doing so reduces social anxiety and threat while providing much desired order and meaning …

(Trans*)Gressing Discourse: Producing And Disrupting Normativity In Education For Trans* Students With Dis/Abilities, Meagan Meredith

Educational Leadership & Policy Studies Dissertations - Archive

This dissertation investigates how political rhetoric, education policy, and educational community member discourse construct, circulate, and contest meanings about trans*ness and dis/ability in K-12 public schools. In doing so, the study examines how meanings about normativity are discursively produced and disrupted for students living at this specific intersection. Grounded in a trans* methodology, this study performs a critical discourse analysis through a rhizomatic reading of policy texts, political rhetoric, and publicly available stakeholder discourse. This work responds to a gap in the literature that fails to understand the complexities experienced by trans* students with dis/abilities, particularly in hostile school climates. …

Adaptive Synchronization In Digital Twin–Enabled Iot Systems: A Unified Framework For Energy, Fidelity, And Latency Trade-Offs, Uzma Zehra

Computer Science and Engineering Theses

Digital twin technology has emerged as a foundational paradigm for enabling real-time monitoring, analysis, and control in Internet of Things (IoT) systems by maintaining virtual representations of physical processes. Its effectiveness, however, critically depends on timely and accurate synchronization between distributed sensing devices and their corresponding digital counterparts. Frequent synchronization improves reconstruction fidelity and system responsiveness but incurs significant communication energy consumption and network latency. In contrast, infrequent synchronization conserves communication resources but can lead to stale or inaccurate digital twin states, particularly in environments with rapidly changing dynamics. These opposing effects give rise to a fundamental trade-off among energy …

Performance Evaluation Of Modified Moisture Barrier For Subgrade Stabilization Of Pavements On Expansive Soils, Md Tamim Shahriar

Civil Engineering Theses

Expansive soils inflict an estimated nine to fifteen billion dollars in annual damage to infrastructure across the United States, surpassing the combined losses from earthquakes, floods, hurricanes, and tornadoes (Nelson and Miller, 1997; Jones and Jefferson, 2012). In Texas, eighteen of twenty-five TxDOT districts contend with pavement failure rooted in moisture-driven volume change of subgrade clay, consuming roughly twenty-five percent of the agency's annual budget for maintenance and repair (Sebesta, 2002; Wanyan et al., 2010). Conventional remediation approaches, including soil replacement, chemical stabilization with lime or cement, and prewetting, are either prohibitively expensive, unsuitable for high-sulfate soils, or confined to …

Supporting Sustainable Art Education: How School Structures Influence Creativity, Michelle Schutz

All Electronic Theses and Dissertations

This study examines how structural conditions within schools influence sustainable teaching practices in visual arts education. Specifically, it explores how class schedules, preparation time, and administrative support shape teachers’ ability to implement creativity-centered instruction aligned with the demands of artistic learning. Drawing on a qualitative synthesis of existing research on instructional time, organizational structures, and educational leadership, this study identifies key patterns in how school systems support or constrain meaningful visual arts instruction. Findings indicate that structural factors, rather than individual teacher characteristics, play a central role in shaping instructional quality and sustainability. Limited instructional time, fragmented scheduling models, insufficient …

The Shareholder Democracy Lie, Sergio Alberto Gramitto Ricci, Daniel J.H. Greenwood, Christina M. Sautter

Hofstra Law Faculty Scholarship

This Article critically examines the fallacious nature of “shareholder democracy” rhetoric and its implications for corporate governance, political democracy, and societal wellbeing. While corporations and activists frequently invoke shareholder democracy to advance their agendas, this concept fundamentally misrepresents the reality of corporate governance and share ownership in America. We systematically debunk the shareholder democracy myth by analyzing historical developments in shareholding, examining barriers to share ownership, and investigating the current state of corporate voting.

The term shareholder democracy first gained popularity in the 1920s, when Wall Street firms and the NYSE used it to attract retail investors while simultaneously helping …
