Abstract

Gerald C Hsu

Recently, the author applied theories of elasticity, plasticity, viscoelasticity, and viscoplasticity from engineering and perturbation theory from quantum mechanics, along with the wave theory and energy theory from physics to conduct his biomedical research on certain output biomarkers, such as glucose (symptoms or behaviors) resulting from a selected input biomarker, such as the carbs/sugar amount, exercise level, or others (causes or stressors). In this article, he chose his synthesized postprandial plasma glucose (PPG) data and waveform over the past 3.8 years as the strain (ε or output, symptom). Since 5/8/2018, he has been utilizing a continuously monitoring glucose sensor (CGM) device to collect 96 glucose data each day and 13 glucose data each meal at 15-minute time intervals. In order to investigate and learn the behaviors of the strain (ε) or PPG, and its stress (σ) or input/cause as defined to be the estimated average glucose (eAG) change rate multiplied by a selected viscosity factor (η), which is the carbs/sugar intake amount. In this study, he selected “elastic” PPG case with average “Finger-piercing PPG <120 mg/dL along with four “plastic” PPG cases, >120 mg/dL, >140 mg/dL, >180 mg/dL, and >200 mg/dL.
