Smart Medical Support System And Swin Transformer Framework For Breast Cancer Detection And Segmentation In Mammograms, Ahed Abugabah, Prashant Kumar Shukla, Piyush Kumar Shukla, Abhishek Dwivedi

All Works

Accurate and reliable breast cancer detection from mammographic images remains a critical challenge due to subtle lesion appearance, high intra-class variability, and class imbalance inherent in clinical datasets. To address these issues, this study proposes Swin-BreastNet, an explainable and optimization-driven deep learning framework for binary classification of benign and malignant breast lesions from full-field digital mammograms. The proposed approach leverages the hierarchical Swin Transformer model to effectively capture fine-grained local texture patterns and long-range contextual dependencies through Shifted Window Multi-head Self-Attention (SW-MSA). A key novelty of this work lies in the integration of Harris Hawks Optimization (HHO) for automated hyperparameter …

Background: Posttraumatic stress disorder (PTSD) in ages 3–18 is associated with disturbances in attention, working memory, processing speed, and executive control, as well as persistent difficulties in affect regulation. These neuropsychological vulnerabilities might interfere with learning, peer relationships, and the consolidation of age-appropriate developmental skills. Methods: We conducted a narrative review informed by a structured literature search in PubMed, Scopus, PsycINFO, Embase, EBSCOhost, Web of Science, and Google Scholar. English-language publications from 1990 to 2025 were considered if they examined (1) neuropsychological outcomes of trauma exposure or PTSD in youth and/or (2) interventions with potential to modify neurocognitive or affective …

Demographic Patterns In The Aesthetic Acceptance Of Building-Integrated Photovoltaics In Apartment Housing: Implications For Solar Energy Design And Policy, Jenan Abu Qadourah, Saba Alnusairat, Rund Hiyasat

All Works

This study examines how demographic and socioeconomic characteristics shape the aesthetic perception of building-integrated photovoltaics (BIPV) in apartment housing. A survey of 418 respondents was conducted using visual scenarios showing PV integrated into rooftops, facades, balconies, and windows. Data were analysed using descriptive statistics, Pearson correlations, one-way analysis of variance (ANOVA) with Scheffé post hoc tests, multiple regression, and thematic analysis of open-ended responses. The results indicate that aesthetic responses to BIPV are not uniform across user groups. Younger respondents, participants with higher educational attainment, and respondents working in energy or technical fields tended to be more receptive to certain …

Public Health Responsible Ai Capability (Ph-Raic) Framework: A Conceptual Model For Integrating Ai Into Public Health Agencies, Arnob Zahid, Ravishankar Sharma, Rezwan Ahmed

All Works

Background: Artificial intelligence (AI) is transitioning from experimental pilots to core public health functions such as disease surveillance, resource planning, and analysis of social and structural determinants of health. Yet, health data collection and stewardship remain fragmented across the globe; some jurisdictions still rely on paper-based systems, while others operate noninteroperable digital systems that can exacerbate inequities. Treating health data as a global good therefore requires governance that enables innovation while protecting rights, safety, and trust. This study aims to develop a conceptual meso-level capability framework that translates responsible AI principles into organizational practices for public health agencies. Methods: We …

Population Pharmacokinetics And Dosing Simulations Of Pentobarbital In The Pediatric Population, Victoria Etges Helfer, Lorena Medina-Aymerich, William J. Muller, Marisa Meyer, Amira Al-Uzri, Russell Mcculloh, Chi D. Hornik, Stephen J. Balevic, Rachel G. Greenberg, Daniel K. Benjamin, Sarah G. Anderson, Daniel Gonzalez

Department of Pediatrics Faculty Papers

Pentobarbital is a barbiturate with sedative and anticonvulsant properties, occasionally used in pediatric patients for preoperative sedation, deep sedation during mechanical ventilation, and seizure control. Despite its long-standing clinical use, age-appropriate dosing remains challenging due to variability across studies and limited pediatric pharmacokinetic (PK) data. This study (NCT01431326) aimed to characterize the population pharmacokinetics of pentobarbital in pediatric patients (birth to 21 years) and evaluate dosing strategies using model-based simulations. A two-compartment population PK model, allometrically scaled to total body weight, adequately described pentobarbital plasma concentrations, with no additional covariates identified as significant. Simulations were conducted across four age groups: …

Federalism, Fragmentation, And The Limits Of Universal Welfare In The United States: A Comparative Analysis Of Germany And Sweden, Jacqueline Arena

Political Science

This paper examines why the United States welfare state struggles to achieve universal social protection, focusing on the role of federalism, political ideology, and public opinion. It argues that the U.S. welfare state is structurally fragmented due to the division of authority between federal and state governments, which produces uneven, inconsistent, and often inadequate access to social benefits. This fragmentation is rooted in historical developments, including New Deal era political compromises, racialized policy exclusions, and resistance from organized interest groups, which embedded decentralization and inequality into the system’s foundation. Using Gøsta Esping-Andersen’s welfare regime typology and T.H. Marshall’s concept of …

Cell-Type Specific Control Of Visual Fixation In Drosophila Melanogaster, Meagan Leung

Biological Sciences

Navigation in complex environments requires precise visual processing. To move effectively through their surroundings, animals must orient toward and maintain fixation on objects of interest to preserve a stable heading. However, the neural mechanisms underlying this behavior remain poorly understood. We use Drosophila melanogaster as our model organism because its visual behavior can be precisely measured and the availability of genetic tools which enables us to perturb the underlying neural circuits. Using a closed-loop virtual reality environment combined with locomotion tracking, we developed a stimulus protocol that reliably elicits fixation responses. To determine whether specific visual neurons drive fixation responses, …

Albany City As A Case Study In Language Mapping, Storm Pupina

Linguistics

This thesis uses Albany, NY, as a case study in urban language mapping, following the example of many other language mapping projects, most notably the NYC Language Mapping Project. Albany's languages and linguistic features were analyzed to better understand the area's linguistic ecology and ongoing heritage-language maintenance efforts. Various types of American Census data were compared to reach the conclusions. Despite not being a major city, Albany is bustling with both new and old language communities. Similar efforts with more varied data-gathering tactics would greatly benefit other American urban landscapes.

Supply Constraints And Domestic Migration As Drivers Of U.S. Housing Price Appreciation, Vasu Patel

Economics

When the Federal Reserve raised rates from near zero to 525 basis points between 2022 and 2023, standard theory predicted a broad correction in U.S. housing market. In most metropolitan areas, that correction did not arrive. This paper examines why housing price appreciation persisted across cities with fundamentally different structural characteristics, and which factors best explain the cross-city variation in appreciation rates observed across the nation. Using a panel of 83 Metropolitan Statistical Areas across four symmetric 24-month periods from December 2017 through December 2025, each aligned with a distinct Federal Reserve rate period, the study estimates OLS models with …

Low-Cost Rf Exposure Monitoring With Tinyml Prediction, Sanad Sahawneh

Nanoscale Science & Engineering (discontinued with class year 2014)

The proliferation of wireless technologies has produced a dense, increasingly heterogeneous radio-frequency (RF) environment that surrounds modern life. While regulatory bodies such as the Federal Communications Commission (FCC) and the World Health Organization (WHO) maintain exposure guidelines, the tools that ordinary people, educators, and small institutions can use to actually observe RF exposure in their own spaces remain expensive, specialized, and largely confined to professional laboratories. Spectrum analyzers and calibrated field probes routinely cost between five hundred and one hundred thousand dollars per unit, placing continuous local monitoring out of reach for most environments where exposure questions are most natural …

The Concentration Controversy, Matthew Urquiaga

Business/Business Administration

This thesis examines how U.S. equity market concentration affects investment performance. Using CRSP data from 1999 to 2024, we construct monthly concentration measures, including the Herfindahl-Hirschman Index (HHI), the adjusted HHI, the Top 20 market share, and each month’s expanding-window concentration quintiles. We document subsequent stock returns by quintile and find weak evidence of higher stock performance in Quintile 3 conditions. A second part of the analysis uses Morningstar’s universe of actively managed U.S. equity funds to evaluate benchmark-adjusted returns (BARs) across the full equity style box. The results show that active managers deliver their highest BARs in moderate concentration …

An Experimental Study Of The Morphology Of Dna-Carbon Nanotube Hybrid Structures In Direct Dna Sequencing, Avery P. Davis

Biomedical Engineering Undergraduate Honors Theses

Hybrid structures formed between single-stranded DNA (ssDNA) and single-walled carbon nanotubes (SWCNT) have emerged as promising components in future direct DNA sequencing technologies due to their unique morphological and electronic properties. The nanoscale configuration of these hybrids, including the DNA wrapping angle, pitch, and contour behavior, directly influences their potential for stable electronic readout. This thesis presents an experimental study of DNA-SWCNT hybrid morphology using a fixed, reproducible wrapping protocol designed to minimize environmental variability and isolate the influence of DNA nucleotide sequence on hybrid structure. As described in prior work, this protocol produces well-dispersed hybrids suitable for high-resolution imaging. …

Long-Term Stimulant Use Is Associated With Normalized White Matter Integrity In The Vta-Nacc Pathway In Adolescents, Isaac T. Arsenault

Biological Sciences Undergraduate Honors Theses

Medical practitioners are diagnosing Attention-Deficit/Hyperactivity Disorder (ADHD) at a high and ever-increasing rate. The use of stimulant medication to treat ADHD is also increasing and is associated with changes in the brain. Past research found that children with ADHD have lower volume in reward neurocircuitry, such as the ventral tegmental area (VTA) and the nucleus accumbens (NAcc). Research has also found that stimulant usage in those with ADHD might “normalize” the reward circuits. However, few longitudinal studies have directly tested the long-term effects of stimulant medication on brain development. Here we tested whether long-term stimulant use is associated with changes …

Host Families’ Perspectives Of The Impact Of The Commodification Of Education On The Student-Host Family Relationship In Study Abroad, Guadalupe Bustamante

Dissertations

The growing commodification of education has reshaped study abroad in ways that extend beyond marketing and program design. While homestays have traditionally been viewed as the ideal format for cultural immersion and language acquisition, research has largely overlooked how these trends affect the student-host family relationship from the family's perspective.

This study examines whether, and, if so, how Spanish host families perceive their roles and relationships with the American students they host have been impacted by these trends. Using a qualitative exploratory case study design, the research focused on representatives from eight families in Madrid, who have hosted U.S. students …

Participants engaged in simulated cognitive and sensory activities that represented experiences associated with dyslexia, ADHD, dysgraphia, and dyscalculia. Although limited by a small sample size, reliance on self-report measures, lack of a pre-survey …

Perceived Campus Safety And Psychological Flexibility As Moderators Of Posttraumatic Stress And Anxiety Following Indirect Exposure To School Gun Violence, Samara Trout

Honors Theses

The growing prevalence of gun violence in school settings within the United States, combined with extensive media coverage of these events, has heightened concerns regarding the psychological impact of indirect trauma exposure among students. The present study examined associations between indirect exposure to gun-based school violence and symptoms of posttraumatic stress and anxiety among undergraduate students at Western Michigan University (WMU). A secondary aim was to explore whether perceived safety and psychological flexibility/inflexibility moderated associations between indirect exposure and psychological distress. Using a cross-sectional correlational design, undergraduate students (N = 33) completed a self-report survey containing screening assessments, attention …

Consumer Willingness To Pay- Mauritius, Addison Guess

Finance Undergraduate Honors Theses

For my thesis, I will be diving into my personal and professional learnings from my summer internship abroad. My group completed a research project in Mauritius, an island off Africa. This island gained independence less than a century ago, and since then, has gone from a low-income farming country to a developing middle-income country with a heavy reliance on rice. Our task was to survey people to determine consumer willingness to pay regarding low glycemic rice. This took place in Mauritius because of the high diabetic rate in this area. Similar to many Asian countries there is a high diabetic …

Phase Equilibria Modeling Constraints On Seismic Velocity And Density For Mafic Granulites In The Athabasca Granulite Terrane, Western Canadian Shield, Olivia Wyllie

Geosciences Undergraduate Honors Theses

Samples of mafic granulite and eclogite from the Athabasca granulite terrane, thought to be representative of the lower continental crust, were analyzed via bulk geochemistry analysis and seismically modelled with Perple_X v.7.1.6. Modeled P-wave speeds, S-wave speeds, and densities for the samples were graphed by region and calculated for wet (1.00 wt.% H2O) versus dry (0.01 wt.% H2O) conditions at 460 °C and 648 °C. The samples were found to have higher median P-wave values than those determined by Rudnick and Fountain (1995; 7.4 km/s to 7.8 km/s, as compared to 6.9 km/s to 7.2 km/s). This indicates both a …

Martha Mitchell: Loud Mouth Of The South, Emma Bernice Kolker

History Undergraduate Honors Theses

In this paper, I will argue how Martha‘s Arkansas identity presents itself as a double edge sword, with her personality attracting the attention of the public with the consent of powerful men in the Republican party, while at the same time her comments and actions were the very reason she was blamed and marginalized by the same men who allowed her to speak in the first place.

Romulus As A Rhetorical And Historiographical Tool In Imperial Roman Literature, Jaden M. Perry

History Undergraduate Honors Theses

This study exames the figure of Romulus in imperial Roman literaure as neither a fixed mythological nor historical subject, but as a flexible rhetorical and historiographical tool. Surveying a range of authors from the late first to fourth centuries CE, inlcuding historians such as Florus, Tacitus, Justin, Suetonius, and the Historia Augusta, as well as literary authors like Juvenal, Silius Italicus, Valerius Maximus, and Seneca, the thesis argues that references to Romulus and his deified counterpart Quirinus are deliberately manipulated to serve distinct authorial purposes. Rather than merely recounting Rome’s foundational myth, these writers employ Romulus to construct comparisons, …

Leveraging Historic Collections: Investigating Morphometric Differentiation In Members Of The Arisaema Triphyllum (L.) Schott (Araceae) Species Complex, Morgan Bradley Russell

Graduate Theses and Dissertations

The Jack-in-the-pulpit (Arisaema triphyllum (L.) Schott) is an herbaceous perennial herb of North America, and its taxonomic history is full of confusion and rank shifts. Now split into six species, the A. triphyllum species complex consists of morphologically similar taxa that have differing ploidy levels. In Chapter I, I compiled a detailed introduction and history for these taxa, focusing on their taxonomic complexity and morphological ambiguity in herbarium specimens and immature plants. I also presented their ploidy distinctions and how the implications of polyploidy may hold answers to parsing them apart, especially in dried herbarium specimens where defining characteristics are …
