Enhancing Search Systems With Large Language Models, Zhiyuan Peng

Engineering Ph.D. Theses

Search systems traditionally balance efficiency and effectiveness by decomposing the retrieval process into a pipeline of query understanding, retrieval, and reranking to surface relevant documents. The rapid progress of large language models (LLMs) is reshaping this paradigm: modern systems increasingly aim not only to retrieve information but to produce direct answers, while remaining reliable, efficient, and scalable. This dissertation, Enhancing Search Systems with Large Language Models, studies how LLMs can improve each stage of the search stack and how new evaluation resources and efficiency measures are needed to deploy LLM-powered search in practice.

First, for query understanding in large-scale e-commerce …

Unnoticed Witnesses Of History: First-Hand Accounts Of Ukrainian Women In South Carolina During Russia's Invasion Of Ukraine, Madeline R. Fyock

Senior Theses

Language and other cultural symbols have become widely contested in post-Soviet Ukraine, especially after Russian President Vladimir Putin’s full-scale invasion in February 2022. The conflict prompted many in Ukraine and its diaspora to re-negotiate and affirm Ukrainian national identity through language, traditions, and culture. The ways in which national identity is signaled in Ukraine has been widely studied in the wake of 2022, but less research has investigated how similar trends are occurring in migratory contexts, where conflict and displacement play crucial roles in identity construction. This study examines the ways that Ukrainian immigrant women in South Carolina signal their …

It further develops a ministry profile emphasizing communion with God, …

Sovereignty As A Shield? The Icc’S Role In Addressing War Crimes In Nagorno- Karabakh, Grigori Sahakyan

UC Law SF International Law Review

This Note argues that the International Criminal Court (ICC) should assert jurisdiction over atrocities from the 2023 Nagorno-Karabakh offensive and pursue prosecutions for war crimes and crimes against humanity. Proper International Humanitarian Law (IHL) classification places the situation in an international armed conflict—via direct interstate action and/or occupation—triggering the full Article 8 framework. Jurisdiction is grounded in Armenia’s ratification and retroactive Article 12(3) acceptance; admissibility is satisfied because Azerbaijan is unwilling to conduct genuine proceedings. While cooperation obstacles remain, targeted enforcement measures can strengthen execution of warrants. The bottom line is doctrinal, not diplomatic: sovereignty cannot shield atrocity crimes; the …

Designing A Novel Inhibitor For Cobalamin-Independent Methionine Synthase, Damon Virgo

Undergraduate Honors Papers

Microbial infections are some of the leading causes of death in the population at large, and antimicrobial-resistant “superbugs” have become a growing issue, so there is a great need to explore new and alternative pathways for fighting these diseases. One method for doing this is by exploring Methionine synthase (MetSyn), which plays a critical role in cellular one-carbon metabolism, catalyzing the methylation of homocysteine to form methionine, an essential amino acid required for protein synthesis and methyl group transfer reactions. Key differences between the B12-independant fungal MetSyn enzyme and the B12-dependant mammalian form can allow for selective targeting of the …

Aggressive R&D Consulting Companies Fail To Align With The Purpose Of R&D And R&E Tax Incentives., Emily Belanger

Michigan Business & Entrepreneurial Law Review

Research and development (R&D) credits and research and experimentation (R&E) tax incentives have recently experienced legislative changes and litigation related to the questionable methods deployed by R&D consulting firms. Proponents of research tax incentives tout their potential to produce positive externalities and innovation. Critics have pushed back, questioning whether research tax incentives are successfully achieving their purpose. The shifting landscape, litigation over aggressive tax claims, and debatable success of tax incentives signal a need to reassess whether research tax incentives are properly claimed in the United States. This paper proposes stronger regulation of R&D consulting firms to ensure research tax …

Leeds V. Norfolk Southern Railway Company—In Undoing Late Removal, District Court Gives Guidance On Evaluating Whether Defendants Were Joined In “Bad Faith”, Geoffrey D. Kearney

SLU Law Journal Online

Pursuant to 28 U.S.C. § 1446, defendants typically have one year to remove to federal court a case filed in state court. The landscape for removal changed somewhat with a 2011 amendment to this statute, which extends that one-year deadline upon a showing “that the plaintiff has acted in bad faith in order to prevent a defendant from removing the action.”

But the question of what sort of conduct satisfies this provision persists. Since its passage, courts—primarily district courts—have grappled with just what it means for a plaintiff to act in bad faith to thwart removal. Leeds v. Norfolk Southern …

A Fully Discrete Decoupled Scheme And Applications For Non-Isothermal Two-Phase Flow Model With Different Viscosities And Thermal Diffusivities, Jian Li, Chunhao Chen, Xiaoyong Chen, Rui Li, Xiaoming He

Mathematics and Statistics Faculty Research & Creative Works

To study natural convection problems in two-phase flows, a non-isothermal two-phase flow model incorporating differential viscosities and thermal diffusivities is considered and analyzed via the phase-field method. This modeling framework involves the Multiphysics coupling of the Cahn-Hilliard phase field equations, heat transfer equation, and Navier-Stokes equations, resulting in a strongly nonlinear system. To efficiently solve the sophisticated system, we develop, analyze, and demonstrate a decoupled linear fully discrete scheme, which leverages the invariant energy quadratization strategy for the Cahn-Hilliard phase field system, the artificial compressibility method without artificial pressure boundary condition, an explicit-implicit treatment of nonlinear terms, and the addition …

Learning About Human Mathematical Dialogue From Dialogue With Chatbots: Babbling, Gargling And Funnelling, Ingólfur Gíslason

The Mathematics Enthusiast

In this study, I explore mathematics teaching-learning dialogues between preservice teachers and a chatbot (ChatGPT) with the aim of increasing our understanding of human mathematics teaching-learning dialogues. The dialogues contain wrong solutions (as determined by the preservice teachers), and the teachers try to get the chatbot to reconsider its answers without giving away the answer. The chatbot’s solution attempts are interpreted through and against the concepts of babbling (imperfect efforts to express thought) and gargling (imitation of surface form of expressions), and the dialogues are analyzed by considering whether and how the preservice teacher and the chatbot reach joint attention. …

Framing Artificial Intelligence In Higher Education: A Narrative Policy Analysis Study Of Higher Education Institutions With Particular Reference To Missouri, Taylor D. Corlee

Missouri Policy Journal

This study examines how higher education institutions narratively frame students’ use of artificial intelligence through policy-related documents, focusing on how these stories shape AI policy and how they can guide Missouri-based research. Using the Narrative Policy Framework and directed content analysis, 59 documents from 12 US public universities were coded for characters, plots, and morals and analyzed with descriptive statistics, Pearson correlations, and difference-of-means tests. Findings reveal that institutions frame AI policy through narratives that cast faculty as guides, students as both capable and vulnerable, and AI as both tools and threat. For Missouri, recognizing how narratives shape AI governance …

Cellular And Molecular Characterization Of Ube3a Function In Cic-Dux4 Sarcoma, Jesse D. Walker

Theses

CIC-DUX4 sarcoma (CDS) is a rare and extremely aggressive soft tissue sarcoma that primarily affects children and young adults. CDS is characterized by an oncogenic chromosomal translocation. Current treatments for CDS are similar to those in other sarcomas like surgery, chemotherapy, and radiation. Treatments, however show that CDS responds poorly compared to other sarcomas, due to relapses of localized disease at high rates and short duration response of treatment, proving the importance of understanding CIC-DUX4’s complex role on how it regulates overall gene expression in CDS cells from a molecular approach.

UBE3A is a ubiquitin protein ligase that plays a …
