Chronic Fatigue Mechanisms in Autoimmune Diseases: Lessons from Primary Biliary Cholangitis and Systemic Sclerosis
DownloadFall 2023
Systemic sclerosis (SSc) is an autoimmune disease affecting the body's connective tissues, resulting in progressive fibrosis and vasculopathy. In some cases, individuals with SSc may also develop primary biliary cholangitis (PBC), another autoimmune disease characterized by damage to their...

The development of accurate models of drift resonance between $H^+$ ions and Alfv\'enic ultra-low frequency (ULF) waves is crucial for understanding particle dynamics in the Earth's inner magnetosphere. However, full solutions to the wave equations are complex and approximations are required to...

Increasingly Parallel Pressure Anisotropic Ballooning Instability: A New Mechanism for Magnetospheric Substorm Onset
DownloadFall 2019
Geomagnetic substorms are a process through which energy stored in Earth’s magnetosphere is suddenly and violently released. On the ground, this process is largely observed as a vibrant and dancing display in the aurorae and is well documented, while the sequence of events that occurs in the...

Electrocoalescence of Water Droplets in Oil Emulsions: Effect of Electric Fields, Surfactants, and Chemical Demulsifiers
DownloadSpring 2019
Stabilization of water-in-oil droplets during bitumen extraction and refining process poses a major challenge in the oil sands industry. These crude oil emulsions are stabilized by rigid films at water droplet-oil interfaces. The salty water remaining in oil causes equipment corrosion, catalyst...

Numerical modeling of drift resonance and drift-bounce resonance between ultra-low frequency waves and energetic particles in the inner magnetosphere
DownloadFall 2018
The main topic of this thesis is the investigation of drift resonance and drift-bounce resonance between energetic particles and Pc3-5 Alfvenic ultra-low frequency (ULF) waves in the Earth's inner magnetosphere. We have developed numerical models to simulate how the dynamics of O+, H+ ions and...

Fluxgate magnetometers are an essential tool for solar-terrestrial research and monitoring or forecasting space weather. They provide high precision measurements of the Earth’s magnetic fields and can be used to infer the currents that transport energy and momentum through the magnetosphere and...

Charged particle behavior in the growth and damping stages of ultralow frequency waves: Theory and Van Allen Probes observations
Download2016
Wygant, John R., Zong, Qui-Gang, Kletzing, Craig A., Blake, J. Bernard, Kivelson, Margaret G., Zhou, Xuzhi, Chen, Xing-Ran, Rankin, Robert, Wang, Zi-Han
Ultralow frequency (ULF) electromagnetic waves in Earth's magnetosphere can accelerate charged particles via a process called drift resonance. In the conventional drift resonance theory, a default assumption is that the wave growth rate is time independent, positive, and extremely small. However,...

Serpe, Michael J., Gao, Yongfeng, Zhang, Qiang M., Ahiabu, Andrews
A series of pyridine-functionalized poly (N-isopropylacrylamide)- based microgels were synthesized. Subsequently, a structured photonic device was fabricated by sandwiching the microgels between two thin Au layers, and their response to CO2 investigated. We show that devices show an optical...
