Quantum Algorithms For Discrete And Combinatorial Optimization, Gloria Oppong

UTC Spring Research and Arts Conference

This study explores quantum computing for combinatorial optimization, focusing on the Traveling Salesman Problem (TSP). Using Qiskit, the Quantum Approximate Optimization Algorithm (QAOA) is implemented on simulators and quantum hardware, and compared with classical optimization using Gurobi. TSP instances are encoded as Quadratic Unconstrained Binary Optimization (QUBO) problems derived from the Miller–Tucker–Zemlin formulation, with quadratic penalties enforcing degree and subtour constraints. Results indicate that QAOA consistently generates feasible tours, but classical branch-and-bound methods achieve better solution quality and runtime. On Noisy Intermediate-Scale Quantum (NISQ) devices, performance degrades with problem size due to sensitivity to parameter tuning, penalty scaling, and hardware …

Community Resilience And Response To Salinity Gradients In Streams Flowing Into Biscayne Bay, Florida, Sebastian M. Jimenez, Francesca Leasi

UTC Spring Research and Arts Conference

Contemporary shifts in global and local salinity dynamics are caused by various factors, including altered global hydrological cycles, poor water management practices, and salt pollution. For my Honor’s Thesis, I explored the effects that salinity has on communities of meiofauna in coastal streams. Meiofauna are small (45-1000 μm) aquatic invertebrates (microinvertebrates). They are taxonomically diverse and vital to the health and function of all aquatic ecosystems and their food webs. I hypothesized that more sensitive taxa will only be found within a narrow range of salinity, while others will tolerate and be found across a greater range. I quantified meiofauna …

Taking Off The Mask: Development Of A Role Method For Late-Diagnosed Neurodivergent Women, Maria Moutzalias

Expressive Therapies Theses

Neurodivergent women are frequently underdiagnosed, misdiagnosed, or late diagnosed due to gender differences and the prevalence of masking. Masking is the unintentional or intentional suppression of neurodiverse traits to present more neurotypical. Consequences of long-term masking can include increased risk of anxiety, depression, and burnout. This study explores the potential of drama therapy as a modality to support unmasking and increasing self-esteem in neurodivergent adult women. Drawing on existing literature on neurodiversity, masking, and drama therapy, a two staged role-based intervention was developed and implemented within a six weeklong psychotherapy group for five late diagnosed neurodivergent women. All participants were …

Hearing And Vision Impairment And Cognitive Function In Later Life: A Scoping Review Of Psychosocial Mechanisms, Lea Guelde

Honors Capstones

Introduction: Sensory impairment is one of the most prevalent chronic conditions in later life and has been consistently associated with poorer cognitive outcomes. While prior research has documented associations between sensory loss and global cognitive decline, less attention has been paid to the psychosocial mechanisms that may explain this relationship. Understanding these pathways is essential for identifying modifiable intervention targets. This scoping review mapped and synthesized the existing literature on associations between hearing and vision impairment and cognitive function in adults aged 60 years and older, with a specific focus on psychosocial mechanisms linking sensory function and cognition in later …

Barriers To Palliative Care Access In Rural South Dakota: A Policy And System-Level Analysis, Harshavardhan Kadarkaraisamy

Genecov, Christopher F. Drescher, Heather Bruschwein, Chelsi N. Nurse, Katherine Lawliss, Darcy C. Esiason, Gunnar H. Esiason

Department of Psychiatry and Human Behavior Faculty Papers

BACKGROUND: Existing mental health self-report measures have been criticized for over-simplification, lack of CF-specific focus, susceptibility to measurement reactivity bias, and conflation of symptoms of anxiety and/or depression with CF-related symptoms and/or treatment side effects. The CF Mental Health and Wellness Questionnaire (CFMHWQ) is a 25-item measure assessing CF-specific mental health burden symptoms.

METHODS: To examine common underlying factors contributing to scores on the CFMHWQ, principal component analysis (PCA) was conducted of all 25 items. We conducted cross-validation of CFMHWQ principal components, examining unadjusted correlations between each principal component, demographic characteristics (age and biological sex), negative affect (mean rank global …

Ultrasound Neuromodulation Reveals Distinct Roles Of The Dorsal Anterior Cingulate Cortex And Anterior Insula In Learning, Nomiki Koutsoumpari, Johannes Algermissen, Siti Yaakub, Hanneke E. M. Den Ouden, Nadège Bault, Elsa Fouragnan

School of Psychology

Pavlovian biases reflect how evolutionarily hard-wired tendencies—automatic approach toward reward cues and withdrawal from threat cues—can interfere with flexible, goal-directed action. Such biases arise through three mechanisms: (a) anticipated rewards energize action while anticipated punishments suppress it (response bias), (b) agents learn differently from actions than from inactions (learning bias), and (c) reward/punishment cues themselves drive repetitive behavior, independent of outcomes (perseveration bias). The neural origin of these biases is unclear. Past evidence suggests dorsal anterior cingulate cortex (dACC) and anterior insula (aIns) as part of a “reset network” that rapidly responds to salient information and might contribute to these …

Host Genetic Variation And Environmental Stress Shape Microbiome Assembly And Host–Microbe–Pathogen Dynamics In Drosophila, Nitin Bansal

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Host-associated microbiomes play central roles in host physiology, development, and susceptibility to disease, yet their composition and stability vary widely across genetic, environmental, and ecological contexts. Understanding the factors that shape microbiome structure remains a key challenge in host–microbe biology. This thesis examines how host genetic background and environmental perturbations independently influence gut microbiome composition in Drosophila, and uses mechanistic modeling to explore how microbial dynamics can affect pathogen invasion outcomes.

In Chapter 1, I investigate how mito-nuclear genetic variation influences gut microbiome structure across developmental stages and generations. Using 16S rRNA sequencing, I show that microbiome composition differs between …

Interparental Relationship Quality Reduces Parental Stress And Subsequent Family Dysfunction Across Pregnancy And Early Childhood, Rachel Clara-Beth Beck

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

In this multiple paper dissertation, I found that a higher quality interparental relationship, characterized by more emotional intimacy, support, responsiveness and better conflict management skills, plays a key role in reducing stress and its subsequent impact on family dynamics. Aims and hypotheses were tested using longitudinal data collected from mixed-sex couples during the pregnancy-postpartum transition and into early childhood. In study #1, higher quality interparental support during pregnancy was associated with lower postpartum stress which, in turn, predicted fewer parent–infant bonding impairments. In study #2, a mutually responsive orientation in the couple relationship during pregnancy interacted with intrapersonal regulatory resources …
