Theoretical Expressivity Of Self-Attention As A Model Of Binary Sequence-To-Sequence Functions And Other Explorations, Dustin Angerhofer

Theses and Dissertations

The self-attention mechanism lies at the heart of modern sequential modeling with deep neural networks, especially in the context of Large Language Models (LLMs). The basic role of self-attention is to capture pairwise interactions between tokens in a sequence. This allows token embeddings to be endowed with context-dependent information before further processing. Despite its widespread use, our theoretical understanding of self-attention is still nascent. In this work, we examine self-attention as a model of binary sequence-to-sequence (seq2seq) functions, which is the simplest non-trivial case to analyze. We find, using VC dimension and the Sauer-Shelah lemma, that in the limit of …

The Lookahead Transformer, Justin P. Olcott

Theses and Dissertations

Large Language Models (LLMs) are transformer models that generate text autoregressively in two stages: prefill and decode. The prefill stage processes all input tokens in parallel and caches them into the KV cache. The decode stage uses the KV cache, processes a single token at a time, and is generally memory-bandwidth constrained. Each decode step generates a token probability distribution, samples from it, appends the token to the cache, and repeats. This left-to-right, one-at-a-time generation paradigm has proven effective for language modeling in many domains; however, it also has limitations such as token permanence, constant compute per token generation, constant …

Iron-Based Nanoparticles As Delivery Tools, Keykavous Parang, Rajesh Vadlapatla, Ajoy Koomer, Victoria Moran, Lanie Jackson, Amir Nasrolahi Shirazi

Pharmacy Faculty Articles and Research

Iron-based nanoparticles, particularly iron oxide nanostructures (IONPs), have emerged as versatile and clinically relevant platforms for drug delivery and theranostic applications. Among these, superparamagnetic iron oxide nanoparticles (SPIONs), including magnetite (Fe₃O₄) and maghemite (γ-Fe₂O₃), are the most extensively investigated due to their biocompatibility, magnetic responsiveness, and established safety profiles. Their unique superparamagnetic behavior enables external magnetic-field-guided targeting, magnetic resonance imaging (MRI) contrast enhancement, and magnetically triggered hyperthermia, enabling simultaneous diagnosis and therapy. Surface functionalization with polymers, silica, lipids, peptides, and biomolecules further improves colloidal stability, circulation time, targeting specificity, and controlled drug …

The Right Of Nature: Lessons From Panama For Mangrove Protection In Miami, Jayson Fry

University of Miami Inter-American Law Review

Mangrove ecosystems are indispensable to climate resilience, yet traditional environmental governance has repeatedly failed to prevent their decline. This Note employs a comparative framework to examine Panama and Miami, two rapidly developing coastal regions facing parallel pressures of urbanization and sea-level rise, to demonstrate that mangrove loss persists not because law is absent, but because existing frameworks structurally authorize regulated degradation. Panama’s 2022 Rights of Nature Law, which grants ecosystems legal personhood and enforceable rights, represents a departure from anthropocentric environmental regulation. Its early judicial application in the Cobré Panamá mine case shows how rights-based protections can override extractive economic …

The Synthesis And Evaluation Of Thioxothiazolidin-4-One Compounds As Pim Kinase Inhibitors, Kelly Malzewski

Master's Theses (2009 -)

The Proviral integration site for Moloney Murine Leukemia virus (PIM) kinases belongs to the family of serine/threonine kinases consisting of three isoforms; PIM1, PIM2, PIM3. PIM kinase is involved in multiple cellular processes through the phosphorylation of several proteins within the JAK/STAT pathway, leading to cell proliferation, apoptosis inhibition, cell migration, transcription, and energy metabolism. However, disruption or overexpression of PIM within the cycle can have negative, tumorigenesis effects with increased fatality rates. Currently, there are no FDA approved PIM kinase inhibitors available for specific cancer target therapies, despite the growing need and high demand research interests. It is widely …

A Proposed Methodology For Online Asynchronous Therapeutic Dreamwork, Gregory Sparrow, Ryan Hurd, Yih-Jiun Shen, Kim Phetteplace

Counseling Faculty Publications

The COVID-19 pandemic accelerated the acceptance of online “telemental” health as an alternative to sitebased service delivery. Concurrently, therapists have adopted various asynchronous virtual mental health resources, such as bulletin boards/forums, delayed chat, and email, to supplement traditional practice. Asynchronous dream sharing, pioneered in the early 1980s, has since supported online conferences and ongoing dreamwork communities. However, the potential of asynchronous therapeutic dreamwork (ATD) still needs to be explored. This article reviews the evolution of asynchronous online dream sharing and proposes that combining it with “co-creative” dreamwork—particularly the FiveStar Method—may generate distinctive contributions while providing greater safeguards than content-focused interpretive …

How Visual Art In Fatty Legs And A Stranger At Home Deepens The Understanding Of Historical Atrocities And Colonial Violence Inflicted On Indigenous Children In Residential Schools In The United States And Canada, Beth Rocco

Student Theses

“I can fix my own hair,” I protested in Inuvialuktun, but she held tight and, with the same motion a bird makes to pull a piece of flesh from a fish, clamped the jaws of the shears down on my braid and severed it” (Pokiak-Fenton 31). This scene in Fatty Legs by Christy Jordan-Fenton and Margaret-Olemaun Pokiak-Fenton, was a deep cut into the soul of a child. The first slash was being taken away from her parents and family. Next was chopping off her hair, a symbol of identity and tribal pride for Indigenous people. The children began their residential …

Improving Reclamation Seeding Success Through Seed Technologies, Surface Preparation, And Microbial Inoculants, Josh M. De Santiago Lazalde

Theses and Dissertations

Revegetation of reclaimed lands is often limited by poor seed placement, unfavorable surface conditions, and reduced biological activity, particularly on steep or physically degraded substrates where broadcast seeding is commonly used. Improving early seeding establishment under these conditions requires approaches that address both physical and biological barriers to seedling development. We evaluated the effectiveness of surface preparation, seed technologies, and microbial inoculants for improving plant establishment in field and greenhouse settings relevant to mineland reclamation. At the field scale (Chapter 1), we investigated the effects of chain harrowing and seed enhancement treatments on the establishment of grasses, forbs, and shrubs …

Detection Of The Presence And Growth Of E. Coli Bacteria In A Droplet-Based Microfluidic System Using Laser Induced Fluorescence, Oshira Peiris

Theses and Dissertations

Antimicrobial resistance is a biomedical event, wherein an infectious microbe becomes non-responsive to the dosage of a particular antibiotic due to previous overuse or overexposure. Currently, agar plate disc diffusion is used as the gold standard for detecting antimicrobial resistance. The possibility of miniaturizing and speeding up detection techniques for antimicrobial resistance is investigated in this thesis. Microfabrication techniques were used in developing two droplet microfluidic systems interfaced with laser induced fluorescence detection. Microfluidic devices were manufactured with different droplet generating geometries using poly-dimethyl siloxane, soft lithography and hydrophobic surface treatment. The microfluidic devices were tested for droplet quality using …

Answers “Go By Water”: Felt Knowledge As An Alternative Epistemology In Othello, Annalisa Gulbrandsen

Theses and Dissertations

William Shakespeare's Othello is fundamentally a play about epistemology--how does one know what he/she knows amidst the sea of words, evidence, and misdirection? Traditionally, the problem of knowledge in Othello has been treated as an intellectual problem of the mind. However, this thesis argues that the play purposefully draws attention to the limits of what the mind can know by way of the eye (what is seen) and ear (what is spoken or heard), instead offering an alternative epistemology that is felt through embodiment. When Desdemona's words no longer have the power to affect what Othello believes, Desdemona's answers to …
