Advancing Cyclic Ion Mobility Mass Spectrometry For Structural Characterization, Isomer Discrimination And Gas-Phase Ion Chemistry, Sudam Shivaji Mane

Theses and Dissertations

This dissertation focuses on the development and application of high-resolution ion mobility-mass spectrometry (IMS-MS) methodologies for gas-phase separation and structural characterization of small molecules, with particular emphasis on epimers, positional isomers, and protomers. In addition to structural separations, this work investigates fundamental aspects of gas-phase ion chemistry using IMS-MS in combination with collision-induced ion activation and dissociation techniques. Advanced separations were performed using cyclic traveling-wave ion mobility spectrometry (cyclic TWIMS), implemented in a commercial cyclic ion mobility-mass spectrometry (cIMS) platform, to systematically evaluate both the capabilities and limitations of high-resolution IMS in resolving subtle structural differences. Initial studies demonstrated that, …

Navigating Diagnostic Ambiguity In Palliative Pediatric Neuro-Oncology: A Conceptual Framework For Suspected Shunt Malfunction And Refractory Hyponatremia, Olivia R. Kaufman, Samira R. Haberman, Christopher M. Ahmad, Miriana Youkhana

Student Publications

Management of suspected shunt malfunction in pediatric patients with terminal brain tumors presents a complex clinical and ethical dilemma. Differentiating mechanical shunt failure from disease progression or metabolic derangement is often radiographically indeterminate, while invasive diagnostics may conflict with palliative goals of care. We present the case of a five-year-old male with relapsed medulloblastoma and cerebrospinal fluid (CSF) dissemination who developed progressive ventriculomegaly and refractory hyponatremia (serum sodium nadir: 120 mEq/L). The clinical course was complicated by the overlap of potential etiologies: shunt failure, syndrome of inappropriate antidiuretic hormone secretion (SIADH) versus cerebral salt wasting (CSW), and terminal disease progression. …

The Promises And Perils Of Using Llms For Effective Public Services, Erina Seh-Young Moon, Matthew Tamura, Angelina Zhai, Nuzaira Habib, Behnaz Shirazi, Altaf Kassam, Devansh Saxena, Shion Guha

Health Services and Informatics Research

Governments are the primary providers of essential public services and are responsible for delivering them effectively. In high-stakes decision-making domains such as child welfare (CW), agencies must protect children without unnecessarily prolonging a family’s engagement with the system. With growing optimism around AI, governments are pushing for its integration but concerns regarding feasibility and harms remain. Through collaborations with a large Canadian CW agency, we examined how LocalLLM and BERTopic models can track CW case progress. We demonstrate how the tools can potentially assist workers in opportunistically addressing gaps in their work by signaling case progress/deviations. And yet, we also …

Residents Vs. Tourists: Understanding The Role Of Coastal Tourism Experience In Conservation Behaviours, Qian Chen, Rong Huang, Jinhua Zhang, Thatsanawalai Imong

Plymouth Business School

This study examines the factors influencing coastal conservation behaviours by integrating the Theory of Planned Behaviour (TPB) with coastal tourism experiences. Conducted in Plymouth, UK, the research assesses how attitudes, subjective norms, perceived behavioural control (PBC), and tourism experiences shape conservation intentions and engagement among residents and tourists. The findings reveal that PBC is the most influential factor associated with conservation intentions in the overall model, while coastal tourism experiences significantly influence engagement, particularly among tourists. Residents' conservation intentions are more influenced by attitudes, whereas tourists are driven by their tourism experiences. These findings highlight the need for tailored conservation …

Characterizing User-Reported Risks Across Llm Chatbots, Lingyao Li, Renkai Ma, Zhaoqian Xue, Junjie Xiong

Computer Science Faculty Research & Creative Works

As Large Language Models (LLMs) become increasingly integral to daily life, users are engaging with multiple LLM chatbots for various needs; however, prior research on LLM risks often remains lab-based or focuses on single LLMs like ChatGPT or singular risks like privacy. To gain a multi-risk, cross-chatbot understanding of user experiences, we analyze Reddit discussions around seven major LLM chatbots using the NIST AI Risk Management Framework. We find that user-reported risks are unevenly distributed and chatbot-specific: ChatGPT is associated with safety and fairness concerns, Gemini with privacy, and Claude with security and resilience. Less frequent risks, such as explainability …

Research outputs 2022 to 2026

Cybersecurity governance is increasingly critical in a digital economy, with board directors playing a central role in shaping organisational resilience. Directors are pivotal in setting cybersecurity strategies and carrying fiduciary obligations that extend to digital risk oversight. This study examines the cybersecurity literacy and governance practices of Australian board directors through a qualitative interview study with 13 participants. Findings reveal a substantial gap in directors' knowledge and confidence, undermining effective oversight and informed decision-making. This deficit limits their ability to interrogate risk reports, challenge assumptions, and steer investment in line with organisational resilience goals. In response, we propose a Board …

Comparative Physicochemical Characterization Of Porcine, Fish, And Bovine Gelatin In Gummy Candies: Toward Halal Nutraceutical Development, Marlyn Dian Laksitorini, Cici Darsih, Nunung Yuniarti, Rumiyati Rumiyati, Mohammad Zainal Abidin

Pharmaceutical Sciences and Research

Gummy candies have emerged as one of the most popular dosage forms for multivitamins and nutraceutical supplements, including those for brain health. Gelatin is the primary gelling agent used to achieve the gummy texture; however, the influence of different gelatin sources on the physicochemical properties of gummies has not been systematically examined. This study investigated the physicochemical characteristics of gummies prepared with porcine, bovine, and fish gelatin. The gummies were evaluated for mechanical properties (gumminess, hardness, cohesiveness, springiness, adhesiveness, and stringiness), color, water activity, antioxidant activity, and protein content. Additionally, the effects of intentional adulteration—specifically the addition of porcine gelatin …

Brief Of The American Immigration Lawyers Association And Immigration Law Scholars As Amici Curiae In Support Of Respondents, Lindsay Nash

Amicus Briefs

Amicus curiae brief submitted by the American Immigration Lawyers Association and immigration law scholars in support of the respondents in Mullin v. Doe and Trump v. Miot before the Supreme Court of the United States. The brief argues that the Temporary Protected Status (TPS) statute strictly limits the Executive Branch's authority to terminate TPS designations and requires continuation of protection unless the statutory conditions justifying designation no longer exist. The amici further contend that TPS serves a critical humanitarian function by protecting individuals from removal, detention, and loss of work authorization while conditions in designated countries remain unsafe.

Mental Models Of Autonomy And Sentience Shape Reactions To Ai, Janet V.T. Pauketat, Daniel Burton Shank, Aikaterina Manoli, Jacy Reese Anthis

Psychological Science Faculty Research & Creative Works

Narratives about artificial intelligence (AI) entangle autonomy, the capacity to self-govern, with sentience, the capacity to sense and feel. AI agents that perform tasks autonomously and companions that recognize and express emotions may activate mental models of autonomy and sentience, respectively, provoking distinct reactions. To examine this possibility, we conducted three pilot studies (N = 374) and four preregistered vignette experiments describing an AI as autonomous, sentient, both, or neither (N = 2,702). Activating a mental model of sentience increased general mind perception (cognition and emotion) and moral consideration more than autonomy, but autonomy increased perceived threat more than sentience. …

Three-Dimensional Imaging Of Neuronal Activation Patterns In Chronic Neuropathic Pain And Opioid Pharmacology, Madeline Martinez

Electronic Theses and Dissertations 2020 - Present

Chronic neuropathic pain severely diminishes quality of life, yet the supraspinal neural circuits that sustain pain perception and mediate analgesic relief remain incompletely characterized. While peripheral and spinal pain pathways are well established, relatively few studies have mapped pain- or opioid-related neuronal activation across the entire brain. This dissertation employed activity-dependent genetic labeling (TRAP2/Ai9), whole-brain tissue clearing, light sheet microscopy, and graph-theoretic network analysis to characterize brain-wide activation patterns across chronic pain and analgesic conditions in mice.

In Chapter 1, we mapped supraspinal neuronal activation in a bilateral spared nerve injury model of chronic neuropathic pain. Although no individual region …

On The Drainage Vortices Of Liquid In A Container With Two Outlets, Radivoje Stankovic

Electronic Theses and Dissertations 2020 - Present

Vortices that form over multiple drainage ports may exhibit a distinct, periodic alternating behavior, whereby the air core moves periodically between different drainage ports. The physical processes which govern this behavior have not yet been explained, despite the widespread and thorough attempts to describe the flow of water through single or multiple outlets. Early experiments on the alternating behavior of this vortex resulted in a nondimensional relation between the alternating frequency and water height and container geometry with an R2 = 0.91. Subsequent 2D PIV measurements of the flow were performed at different laser heights of 25 mm and 128 …

Evaluating The Geographic Patterns In Isotopic Composition For Nesting Hawksbill Sea Turtles In The Wider Caribbean By Coupling Satellite Telemetry And Stable Isotopes, Anna Kreiger

Electronic Theses and Dissertations 2020 - Present

Combining satellite telemetry and stable isotope analysis offers a framework for inferring sea turtle foraging habitats when spatial isotopic gradients exist. We evaluated this combined approach using carbon (δ13C) and nitrogen (δ1⁵N) isotope values from critically endangered hawksbill turtles (Eretmochelys imbricata) nesting at Buck Island Reef National Monument, U.S. Virgin Islands (N=31), and Long Island (Jumby Bay), Antigua (N = 31). Nesting females were satellite-tracked to identify foraging areas and sampled for skin tissue, and Empirical Bayesian Kriging was used to generate basin-scale δ13C and δ1⁵N isoscapes. Tracked turtles foraged widely across the Caribbean Basin, including the Greater …

All Works

This study provides a systematic review of hydrodynamic roughness in coral reef systems, focusing on drag coefficient (Cd), Manning's roughness coefficient (n), friction factor, and rugosity metrics. A structured bibliometric analysis was conducted using Scopus and Web of Science databases, including field measurements, laboratory flume experiments, and numerical studies validated with physical data. Results show substantial variability in roughness parameters across scales and environments. Reported drag coefficients range from 0.002 for smooth sandy beds to values exceeding 7.0 in complex mangrove-reef systems, with typical reef crest values between 0.05 and 0.30. Manning's n varies from 0.01 in smooth channels to …

Weed Seed Burial And Long-Term Viability Following Soil Inversion, Catherine Borger, Sultan Mia, Gaus Azam, Stephen Davies

Grain and Other Field Crops Research Articles

Strategic soil inversion is advocated as a periodic weed management strategy, typically recommended every 4 to 8 yr if the goal is to delay the evolution of herbicide resistance. It is assumed that the weed seeds buried during the inversion process will lose viability during this period. However, long-term seedbank persistence following soil inversion has not been investigated. If the buried seeds retain viability, subsequent inversions or other deep-tillage operations may return them to the soil surface, potentially replenishing the weed seedbank. The current study identified 30 sites within the wheatbelt of Western Australia (in 2020) that had previously been …

Investigating The Relationship Between Psoriatic Arthritis And Peyronie’S Disease: A Case Study Analysis, Michael J. Evans, Vincent J. Schmidt, Benjamin Kossman, Dylan Hafer, Curtis King

Student Publications

The relationship between psoriatic arthritis (PsA) and Peyronie’s disease (PD) remains poorly understood. PsA is a chronic immune-mediated inflammatory disease, whereas PD is a fibroproliferative disorder of the penile tunica albuginea that leads to penile curvature, pain, and sexual dysfunction. Both conditions involve chronic inflammation and dysregulated tissue remodeling. We report the case of a 42-year-old man with long-standing PsA who developed acute inflammatory PD shortly after discontinuing biologic therapy because of loss of insurance and medication nonadherence. The patient presented with new-onset penile pain and a palpable dorsal plaque in the setting of uncontrolled psoriatic disease. Penile ultrasound demonstrated …

Application Identification With Pfsense, Snort, And Openappid In Academic Lab Networks, Minh-Khanh Vu

Journal of Cybersecurity Education, Research and Practice

This paper evaluates the practical capabilities and limitations of a widely used open-source network security stack—pfSense firewall, Snort Intrusion Detection System (IDS), and OpenAppID detectors—in academic cy- bersecurity laboratories and small-to-medium enterprise (SME)-like environments. In a controlled virtual testbed, we measure application-level and feature-level identifi- cation performance for major applications (Facebook, YouTube, Zoom) using the pfSense/Snort/OpenAppID configuration. The stack achieves 97% application-level identification accuracy for these applications in our lab dataset, drawing on a library of 3,374 OpenAppID detectors. However, our experiments reveal a substan- tial feature-level detection gap: specific functions such as Zoom file transfers and Facebook messaging can- …

Jurnal Pendidikan Humaniora

This study aimed to scrutinize EFL teachers’ strategies and challenges of character building in online and face-to-face classrooms. This case study involved two seventh grade English teachers as the subjects. The findings revealed that the teachers’ strategies of character building in seventh grade EFL classrooms were through the use of speech acts, modeling, rule reinforcement, and habituation. However, the strategies to use in the online and face-to-face classrooms were different. The challenges the teachers faced during the teaching and learning process were time allotment, the absence of English in some elementary schools, and the zoning system.

Racial Bias In Jury Selection: The Fundamental And Pragmatic Issues With Batson Challenges, Abigail Lindsey

Arkansas Law Review

In April of 2024, the District Attorney of Alameda County in California revealed evidence of “serious misconduct” by several prosecutors who oversaw a murder trial in 1993, in which the jury found a Black man guilty and sentenced him to death. The evidence of misconduct included the prosecutors’ trial notes. The notes that have been released suggest the prosecutors struck potential jurors from the jury pool because they were Jewish—the notes include: “I liked him better than any other Jew but no way.” The District Attorney is now looking into the county’s other death penalty cases, some of which took …

Joint Representation Of Spouses And Romantic Partners: Ethical Considerations For Estate Planners, Elizabeth R. Carter

Arkansas Law Review

Attorneys routinely represent married couples jointly in estate planning matters. Joint representation of married couples—and, increasingly, unmarried romantic partners—is a routine practice for most estate planners. This practice was not always so widely accepted. Beginning in the 1990s, scholars, attorneys, and interest groups successfully advocated for the widespread acceptance of joint representation in estate planning. In a joint representation, the attorney represents both individuals in a collaborative form of representation where confidences and goals are shared between both clients and the attorney. Proponents of joint representation in the estate planning setting argue that it reduces costs, is more consistent with …
