Building Trustable Methods For Group Recommendations: Advancing Fairness And Robustness Across Domains, Siva Likitha Valluru

Theses and Dissertations

On the internet, where the number of available choices for information is exponentially growing, there is a need to prioritize and deliver relevant results to users efficiently, on demand. Recommendation systems (RSs) address that need by searching through and filtering large amounts of dynamically generated information and providing users with recommendations tailored to them. These systems have primarily focused on (1) single-user models, where recommendations are tailored towards a specific individual, or (2) single-item models, where items are recommended based on a broader appeal to users and similarities in item metadata, in the past. In many real-world scenarios, however, recommendation …

The Effects Of Acute Nutrient Intake On Raw Segmental Bioelectrical Impedance Values And Fluid Shifts In Premenopausal Women, Callie Unrein

Theses and Dissertations

Background: Raw bioimpedance measures—impedance (Z), resistance (R), reactance (Xc), and phase angle (PhA)—are emerging tools to assess hydration, cellular integrity, and muscle quality. While multifrequency bioimpedance analysis (MF-BIA) can detect acute physiological shifts, its sensitivity to nutrient intake, especially across hormonal phases in women, remains underexplored. Purpose: This study investigated how essential amino acids (EAA), carbohydrates (CHO), and water (CON) influence postprandial segmental bioimpedance and fluid distribution in healthy women, and whether these responses vary by menstrual hormone phase.
