Anomalous Collective Modes In Atomic Nuclei Within The Proton-Neutron Interacting Boson Model, Wei Teng, Yu Zhang, Sheng Nan Wang, Feng Pan, Chong Qi, J. P. Draayer

Faculty Publications

Novel collective modes characterized by a B4/2 ratio (≡B(E2;41⁺→21⁺)/B(E2;21⁺→01⁺)) less than 1.0 that were observed recently have been identified within the proton-neutron interacting boson model (IBM-2) using the consistent-Q Hamiltonian. These modes are shown to give rise to triaxial spectral features, including significant band mixing. The results provide a compelling explanation for the deeply suppressed B4/2 ratio observed in ¹⁶⁶W, ^168,170Os, and ¹⁷²Pt, offering new insights into the B(E2) anomaly phenomenon in neutron-deficient nuclei.

Theory Of Two-Level Tunneling Systems In Superconductors, Junguang He, Wei Ting Lin, J. A. Sauls

Faculty Publications

We develop a field theory formulation for the interaction of an ensemble of two-level tunneling systems (TLSs) with the electronic states of a superconductor. Predictions for the impact of two-level tunneling systems on superconductivity are presented, including Tc and the spectrum of quasiparticle states for conventional BCS superconductors. We show that nonmagnetic TLS impurities in conventional s-wave superconductors can act as pair-breaking or pair-enhancing defects depending on the level population of the distribution of TLS impurities. We present calculations of the enhancement of superconductivity, both Tc and the order parameter, for TLS defects in thermal equilibrium with the electrons and …

Quantum Classical Algorithm For The Study Of Phase Transitions In The Hubbard Model Via Dynamical Mean-Field Theory, Anshumitra Baul, Herbert Fotso, Hanna Terletska, Ka Ming Tam, Juana Moreno

Faculty Publications

Modeling many-body quantum systems is widely regarded as one of the most promising applications for near-term noisy quantum computers. However, in the near term, system size limitation will remain a severe barrier for applications in materials science or strongly correlated systems. A promising avenue of research is to combine many-body physics with machine learning for the classification of distinct phases. We present a workflow that synergizes quantum computing, many-body theory, and quantum machine learning (QML) for studying strongly correlated systems. In particular, it can capture a putative quantum phase transition of the stereotypical strongly correlated system, the Hubbard model. Following …

Blueprint For A Youth Violence Intervention Program In East Baton Rouge Parish: Adapting Hospital-Based Strategies, Kristina G. Little, Elizabeth Winchester, Judith L F Rhodes

Reports

Youth violence in East Baton Rouge Parish remains a persistent public safety and public health challenge. This report proposes an adapted, evidence-informed model for East Baton Rouge Parish that retains the core components of traditional HVIPs while leveraging existing legal, hospital, and social service resources. The model is grounded in a public health framework and emphasizes trauma-informed, bedside intervention at the “teachable moment” when youth are most receptive to change, and long-term wraparound case management. The report concludes with recommendations for implementing this adapted approach, including identifying a health system champion, building referral protocols, embedding training, and developing a long-term …

‘I Can Kind Of Flow How I Want To Flow’: Motivations And Perceived Contrasts Of Providing Care In Home-Based Settings, Erin Harmeyer, Brittany Wittenberg Camp, Catherine Moon

Faculty Publications

The number of family child care (FCC) providers in the United States, or providers who are licensed, certified, or registered to provide care in their home, fell by nearly half between 2005 and 2017 (NCEQA, 2020a). This has implications for families who prefer FCC settings. Understanding providers’ motivations for starting their program may provide policymakers with information on how to better support providers drawn to this setting. Through interviews with 30 Black/bi-racial FCC providers, we found providers started their programs to support family/neighbors, to provide an alternative perceived to be safer than center-based programs, and to be in charge. In …

Interval Spectrum For Electric Quantum Walk And Related Skew-Shift Cmv Matrices, Fan Yang

Faculty Publications

We show that for a family of quantum walk models with electric fields, the spectrum is the unit circle for any irrational field. The result also holds for the associated CMV matrices defined by skew-shifts, as well as a family of the Blattner and Browne model. Generalizations to CMV matrices with skew-shifts on higher dimensional torus are also obtained.

Measuring Children’S Reward And Punishment Sensitivity: An Initial Psychometric Evaluation Of The Contingency Response Rating Scale, Daniel A. Waschbusch, Vanessa T. Cao, Delshad M. Shroff, Pevitr S. Bansal, Michael T. Willoughby

Department of Psychology Faculty Scholarship and Creative Works

Existing research shows that children’s responses to rewards and punishments are essential for understanding attention-deficit/hyperactivity disorder, oppositional defiant disorder, conduct disorder, and callous-unemotional traits. The present study developed the Contingency Response Rating Scale (CRRS) to fulfill the need for a reliable and valid measure of children’s contingency response style that is brief, easy to use in applied settings, and provides additional information to existing clinical measures. We examined the psychometric properties of the CRRS in a sample of 196 children (ages 5–12), most of whom were referred to evaluate attention and behavior problems in an outpatient clinic. Using principal axis …

Enhancing Autonomous Vehicle Resilience Through Engineering Requirements And Snow-Adaptive Lane Detection, Alexandra Marie Masterson

Masters Theses

This thesis investigates two distinct but interrelated challenges in the development of resilient autonomous vehicle (AV) systems: the formalization of engineering requirements for AV perception subsystems and the enhancement of visual lane detection under snow-covered road conditions. In the first study, field experiments were conducted using a campus-deployed autonomous research vehicle to evaluate the impacts of perception related failures including GPS outages, HD map inconsistencies, and weather interference—on vehicle operation. These findings were used to develop a set of qualitative engineering requirements that promote AV resilience through proactive design. In the second study, a custom snow-focused lane detection dataset was …

An Evaluation Of The Role Of Conditional And Unconditional Probabilities In A Precursor Functional Analysis, Cassie Ross

Masters Theses

Functional analysis assessments are extremely useful tools in determining the function of challenging behavior and designing behavior intervention plans (Iwata et al. 1982/1994), but in the case of severe challenging behavior, can be dangerous to the individual or assessor. Precursor functional analyses place the contingencies onto a precursor to the severe challenging behavior and have been shown to be an effective assessment with high correspondence to a traditional functional analyses (Rahaman et al. 2024). This study utilized a probability analysis to identify precursor behaviors and assess the time required to identify precursors. We used a modified Functional Assessment Interview to …

Raters engaged in guided consensus-building discussions to align scoring criteria. Interrater agreement was measured using Kendall's coefficient of concordance (W). Results: The inter-rater agreement improved from moderate (W = 0.461) to substantial …

Understanding Perspectives On Nonstructural Strategies In Louisiana's Southwest Coastal Project, Fenstermaker, Restore The Mississippi River Delta, Uno-Chart

CHART Publications

The Southwest Coastal Louisiana Storm Risk Management and Ecosystem Restoration Project (referred to as the SW Coastal project) is a project run by the U.S. Army Corps of Engineers (Corps) to reduce hurricane and storm damage risk in a 4,700 square mile area located in Calcasieu, Cameron, and Vermilion Parishes. Due to the low elevation, flat terrain, and proximity to the Gulf of Mexico in these Parishes, the people, economy, environment and cultural heritage are at risk of flooding from tidal surge and waves from tropical storms. Land subsidence, combined with sea-level rise, is expected to increase the potential for …

Measuring Collective Impact Of Extension Programs Addressing Substance Use And Mental Health, Omolola A. Adedokun, Olumuyiwa M. Desmennu, Alex Elswick, Nichole Huff, Brooke Jenkins, Katherine Jury, Heather Norrman-Burgdolf

Journal of Human Sciences and Extension

Extension excels at working across program areas and disciplinary boundaries inside and outside land-grant institutions to address complex social issues within communities. However, evaluation of the collective impact of these concerted programmatic initiatives remains a persistent challenge for Extension. To better understand the broader impact of Extension’s cohesive, concurrent response to complex issues such as substance use and mental health, there is a need to shift from isolated evaluations of individual or single Extension programs to a focus on collective impact assessment. This article describes the University of Kentucky Extension planning process and outputs of a collective impact evaluation initiative …

Multiplicity As An Ai Governance Principle, Michal Shur-Ofry

Indiana Law Journal

As AI becomes increasingly embedded in our daily lives, this Article explores one of its critical, yet overlooked, societal implications: the propensity of large language models (LLMs) to generate mainstream, standardized content, potentially narrowing their users’ worldviews.

Taking a close look at the technological underpinnings of LLMs, the analysis suggests that—due to the combination of human judgments, training datasets, and inherent features of the underlying technological paradigm—LLMs’ outputs are likely to be geared toward the popular and to project to their users concentrated, mainstream worldviews, sidelining a broader spectrum of perspectives. This Article explores the asymmetrical power relations between LLMs …

Unpacking Open Source Bio, Jorge L. Contreras

Indiana Law Journal

For at least a quarter of a century, life science researchers around the world have undertaken initiatives loosely based on principles, goals, and institutional structures derived from the open source software (OSS) movement—approaches that I term “open source bio.” Yet open source bio lacks a clear definition and set of guiding principles. Given public calls for greater openness in life science research, it is useful to understand how open source bio projects have fared over the past quarter century: how they were structured, what they hoped to achieve, and, as social and policy experiments, whether or not they were successful. …

Discord And The Pentagon's Watchdog: Countering Extremism In The U.S. Military, Amy Gaudion

Indiana Law Journal

In his 2022 book, Ward Farnsworth crafts a metaphor from the lead-pipe theory for the fall of Rome to consider how rage and misinformation traveling through today’s technology-enabled pipes are poisoning our civic engagement and threatening our governmental structures: “We have built networks for the delivery of information––the internet, and especially social media. These networks too, are a marvel. But they also carry a kind of poison with them. The mind fed from those sources learns to subsist happily on quick reactions, easy certainties, one-liners, and rage.”1 This Article carries the metaphor into a new context and considers what should …

On Software Bugs And Legal Bugs: Product Liability In The Age Of Code, Asaf Lubin

Indiana Law Journal

Despite software’s ubiquity in modern life, its classification within product liability law remains unsettled. Is software a product, a service, a good, a component, a medium, a force, or something else altogether? Under the Restatement (Third) of Torts, a product is defined as a “tangible personal property distributed commercially for use or consumption.” But has this definition been embraced by states? And how has it been applied in the courts, since its adoption some twenty-six years ago?

Through a fifty-state survey and the canvassing of all relevant case law, this Essay reveals widespread doctrinal inconsistencies within the common law. Some …

Defragging Ownership: How Corporations Sliced, Diced, And Sold The Bundle, Joao Marinotti

Indiana Law Journal

Personal property ownership is in a precarious state, facing structural, economic, and legal assaults. As a result, the autonomy, security, and privacy that ownership once protected have been displaced by a tenuous reliance on opaque contractual arrangements and corporate goodwill. Owners no longer enjoy the unfettered right to access, use, and control their personal property. Through a range of seemingly unrelated business practices, companies have leveraged their growing power to disaggregate the property bundle into compartmentalized rights and privileges, which can then be individually licensed, leased, restricted, or even revoked. Purchases no longer mark the end of buyer-seller relationships; instead, …

Efficient Blending Of Large Language Models, Sandeep Chatterjee

Master’s Dissertations

Due to the limited capabilities of single Large Language Models (LLMs), multiple LLMs can be employed in tandem for better reliability of answers. Blending refers to combining the strengths of various LLMs to make use of their complementary capabilities for generating high-quality responses. It is a non-trivial problem, and the task becomes even more difficult when aiming for minimal latency and supervising the blending components. The standard framework, LLM- Blender, approaches this in three stages: response generation, candidate selection via ranking, and response fusion through summarization. However, this pipeline faces two critical limita- tions—high latency due to repeated ranking steps, …

Geometry Based Uav Trajectory Planning For Mixed User Traffic In Mm Wave Communication, Sk Abid Hasan

Master’s Dissertations

Unmanned aerial vehicle (UAV) assisted communication is a revolutionary technology that has been recently presented as a potential candidate for beyond fifth-generation millimeter wave (mmWave) communications. Although mmWaves can o↵er a notably high data rate, their high penetration and propagation losses mean that line of sight (LoS) is necessary for e↵ective communication. Due to the presence of obstacles and user mobility, UAV trajectory planning plays a crucial role in improving system performance. In this work, we propose a novel computational geometry-based trajectory planning scheme by considering the user mobility, the priority of the delay sensitive ultra-reliable low-latency communications (URLLC) and …

Word Level Attack For Text Ranking, Tanmay Karmakar

Master’s Dissertations

Neural Ranking Models (NRMs) have become state-of-the-art in information retrieval, demonstrating remarkable effectiveness across various search and ranking tasks. However, their increasing deployment in real-world systems raises critical concerns about their robustness and susceptibility to adversarial attacks. This project investigates the fragility of modern NRMs by proposing and evaluating a document perturbation method based on targeted, single-word perturbation. Our approach strategically identifies an influential word depending on the query to be substituted or added in the document. We have done experiments on benchmark datasets to assess the impact of these minimal perturbations on ranking performance. Our findings reveal that even …
