    Syn4MD: Aiding Medical Diagnosis through Image Synthesis and Classification
    Abstract Medical trainees depend on diverse visual reference material to develop diagnostic pattern-recognition skills, yet such material is often limited in diversity and accessibility. This paper presents a classifier-in-the-loop generative framework for synthesising realistic histopathology images: a Stable Diffusion v1.5 model is fine-tuned using Low-Rank Adaptation (LoRA) on the PathMNIST dataset, consisting of nine colorectal […]

    DiaBreath: Multivariate Analysis of a Non-Selective Low-Cost Metal Oxide (MOX) Sensor Array for Breath-Based Diabetes Screening
    Abstract The number of diabetes patients is increasing worldwide, but many cases stay undiagnosed in low-resource regions. The A1C blood test is invasive and costly, therefore it is often not available in these regions. In this research, DiaBreath is proposed as a low-cost noninvasive screening system based on exhaled breath analysis. Volatile organic compounds (VOCs) […]

    A Statistical Physics Approach to Market Dynamics: Regime Shifts in Digital vs. Local Vendor Choice
    Abstract Digital commerce platforms compete with local vendors under frictions of time, price, and visibility. We test whether an interpretable choice model with reinforcement and social influence can yield substantial changes in aggregate market share as control parameters vary. We simulate repeated customer choice among vendors using a utility function that combines vendor attributes (price, […]

    Predicting Limited Service Zones Using GIS-Integrated Machine Learning: A Case Study of Three Cities
    Abstract Local businesses are important to neighborhood service access, but access to these services is limited in some areas. This study uses GIS and machine learning to identify possible limited service zones for restaurants and supermarkets across Dublin, Pleasanton, and Livermore in Alameda County, California. The model dataset included 1,134 Alameda County census block groups, […]

    The Economics of Efficiency: How Energy Performance Shapes Capital Formation in AI Infrastructure
    Abstract AI depends on data centers, which need large amounts of electricity and capital to build. Energy efficiency at these facilities is usually treated as an engineering question, but it may also shape how that construction is financed. This review asks whether Power Usage Effectiveness (PUE), the standard efficiency metric, affects cash flow, collateral value, […]

    Concordance of CARD/RGI, ResFinder, and BV-BRC Workflows for ESBL Allele Detection in 100 Escherichia coli Genomes
    Abstract Extended-spectrum beta-lactamase (ESBL) genes confer resistance to extended-spectrum cephalosporins. Genomic analysis tools may report differing results due to distinct databases and detection rules. This study compared CARD/RGI, ResFinder, and current BV-BRC Comprehensive Genome Analysis using the same set of Escherichia coli genomes and the reconstructed sequence-level ESBL reference. One hundred study rows were examined. […]

    Measuring and Shaping Gender Bias in Text Embeddings and Classifiers
    Abstract Gender bias is present in machine learning models used for tasks like sentiment analysis, hiring, and recommendations without gender as an input. This study examines two areas: gender and sentiment relationships in pre-trained text embeddings and how biased training data and classifier architectures can lead to unfair decisions. A cosine-similarity permutation test was conducted […]

    Environmental and Behavioral Determinants from Adolescence to Early Adulthood and Their Contributions to Long-Term Alzheimer’s Disease Risk
    Abstract This literature review examines how environmental determinants such as diet, exercise, stress, and pollution throughout adolescence affect the risk of later life Alzheimer’s disease development. Alzheimer’s disease is a growing global health concern with recent estimates of affected individuals continuing to rise. These estimates align with prior epidemiological projections, confirming its accelerating worldwide threat. […]

    Computational Analysis of Magnetorheological and Passive Dampers in Simulated Rocket Landings
    Abstract During the final touchdown phase, rockets face significant impact loads within brief durations (<100 milliseconds). The dampers integrated into the landing legs are used for absorbing energy and preventing excessive force transmission to the rocket’s main frame. This study explores the potential of magnetorheological (MR) dampers, which are able to dynamically adjust their damping […]

    Colorimetric Assay of Commercial Lactase Solution Under Different Storage and Solution Conditions
    Abstract Protein stability depends on storage temperature, solution composition, and concentration. This study tested how a 25 mg/mL solution prepared with commercial β-galactosidase (lactase) powder preserved its activity after a short room-temperature exposure and whether glycerol, a common protein stabilizer, helped retain activity under the same temperature treatment. Each of the three independently prepared blocks […]

    Automated Highlight Generation of Amateur Table Tennis Videos Using Machine Learning
    Abstract The widespread use of smartphones has made it common for amateur players to record table tennis matches. However, active gameplay can account for less than half of the recording time (about 40% in our annotated match recordings), making manual review and highlight creation time-consuming. This study describes a machine learning system that automatically generates […]

    A Modelling-Based Assessment of Hybrid SMR-Renewable Power Systems for High-Density AI Data Centers
    Abstract Background/Objectives: The rapid expansion of artificial intelligence (AI) workloads is increasing the power density and thermal-management burden of data centers. This study evaluates whether a hybrid small modular reactor (SMR), solar photovoltaic (PV), battery-storage, and advanced-cooling configuration can internally balance high-density AI demand under clearly stated modelling assumptions. Methods: A deterministic, scenario-based model was […]

    Numerical Exploration of HOBO vs. QUBO: Using Sudoku as a Benchmark
    Abstract Sudoku, with its complex combinatorial structure, provides a natural NP-hard benchmark for testing optimization models. In this study, we quantitatively compare Quadratic Unconstrained Binary Optimization (QUBO) and Higher-Order Binary Optimization (HOBO). While QUBO is compatible with quantum computers, it is often evaluated on classical simulators known as quantum simulators which calculates with tensor network […]

    Unequal Punishments: The Effects of Family Characteristics and Ethnicity on Student Suspension
    Abstract Does a high school student’s family characteristics and ethnicity affect their rate of suspension? Racial disparities in suspension rates are well documented and two conflicting explanations are prevalent in previous literature. The first attributes the gap to differences in socioeconomic status and a student’s situation. The other suggests that institutional factors cause this disparity. […]
