The Impacts Of Emotions On Thirst Among Heart Failure Patients, Chieh-An Yang, Hsing-Mei Chen, Tsung-Neng Tsai, Chieh-Yu Liu, Hui-Ju Lu, Ting-Ti Lin

International Nursing Research Congress (INRC)

Purpose: Thirst, characterized by sensations of oral dryness and a craving to drink, is a ubiquitous experience among heart failure (HF) patients. Besides reduced cardiac output, the clinical treatments for HF patients (e.g., diuretics, fluid restriction) may activate the renin-angiotensin-aldosterone system (RAAS), exacerbating their thirst distress.

Negative emotions are commonly experienced among heart failure patients. Previous studies have suggested that emotions (e.g., anxiety, depression) may activate the sympathetic nervous system, reducing the secretion of saliva, which, in turn, may increase sensations of dry mouth among HF patients. However, the relationship between emotions and thirst distress remains unclear. Therefore, the aim …

Operational Resilience In Cubesat Tracking Operations Through Complementary Architectures At Dss-17, Andrea Togni, Emily Walter, Chloe Hart, Ryan Collins, Noah Patrick, Christo Smith, Nathan Fite, Benjamin Malphrus, Marc Sanchez-Net

Small Satellite Conference

Loss of phase-locked loop (PLL) lock during CubeSat tracking can simultaneously eliminate both telemetry and Doppler observables, leaving operators blind during critical mission phases. While closed-loop receivers provide high-precision tracking under nominal conditions, they remain vulnerable to low signal-to-noise ratio, rapid Doppler dynamics, oscillator instability, and modeling errors. This single-point failure mode reduces operator situational awareness precisely when it is most needed. This work presents a dual-acquisition architecture that eliminates single point failure in CubeSat ground tracking. Implemented at DSS-17, Morehead State University's 21-meter deep-space antenna, the system pairs a conventional closed-loop modem with a parallel open-loop receiver implemented on …

The Billion Dollar Surprise: How Solar Cycle 25 Cut Satellite Lifetimes In Leo, Scott Shambaugh

Small Satellite Conference

Solar Cycle 25 has run far stronger than the 2019 consensus forecast issued by the NOAA/NASA/ISES prediction panel, with densities in low Earth orbit from 2022-2026 holding at 2-3x the predicted levels. The cumulative drag impulse experienced by LEO satellites, which is the driving metric for propellant budgets and mission lifetimes, reached 5-6 standard deviations beyond the forecast’s stated uncertainty. This means that even operators who designed conservatively against the two-sigma worst case fell short of their drag budgets. This paper quantifies a lower bound on the economic cost of that misprediction.

Starting from the 13,704 payloads on-orbit below 800 …
