- Description:
- Radiofrequency ablation is a minimally-invasive treatment method that aims to destroy undesired tissue by exposing it to alternating current in the 100 kHz to 800 kHz frequency range and heating it until it is destroyed via coagulative necrosis. Ablation treatment is gaining momentum especially in cancer research, where the undesired...

- Description:
- The dynamics of human joints are fundamental characteristic of the human motor system, and altered joint impedance can hinder mobility. Individuals with transtibial amputation typically experience slower and energetically costly gait, while individuals with chronic stroke experience persisting gait deficits arising from spasticity, hypertonia and paresis. Investigating joint impedance of...

- Description:
- NiTi shape memory alloy (SMA) has drawn a great deal of attention for its various applications in the medical field (orthodontics, cardiovascular stents technology, etc.) and in other engineering fields (aerospace, aircraft, automotive, etc.) as it shows shape memory effect, superelasticity and biocompatibility. The fatigue-related issues, however, are pronounced in...

- Description:
- Movement and sensing fundamentally works in a synergistic manner. Animal's sensory organs --- be they independently movable like eyes or requiring whole body movement as in the case of electroreceptors --- are actively manipulated throughout stimulus-driven active sensing behaviors. Though these sensing-related motions have been individually reported and analyzed across...

- Description:
- Despite prevention and treatment, substantial risk for cardiovascular disease(CVD) remains in the population and CVD has been the leading global cause-of-death in past years.While high-density lipoprotein (HDL) markers such as HDL cholesterol (HDL-C) and HDL efflux (a cholesterol-transport-function assay) are associated with decreased risk of CVD, the mechanism of this...

- Description:
- Staphylococcus aureus (SA) is a leading cause of healthcare-associated and community-acquired infection in the United States. Despite the canonical thinking that antibodies and B cells are the main drivers of protection against extracellular pathogens, T cells are now recognized as critical players in protection against SA in multiple routes of...

- Description:
- “Entertaining Strangers” reveals how theories and practices of hospitality shaped and were shaped by the early modern print and theater industries. Whereas earlier studies of hospitality and literature have focused on aristocratic patronage, in this dissertation I reveal the vital importance of commercial hospitality as a framework for ethical and...

- Description:
- Physiochemical phenomena in aqueous systems, such as corrosion, catalysis, and energy storage, are driven by the molecular-scale interactions of ionic species with charged solid surfaces. In particular, an electrical double layer (EDL) of ions forms within nanometers of a charged surface. The properties of the EDL have been explored from...

- Description:
- Following the discovery of n-type Mg3Sb2−Mg3Bi2 alloys, attempts have been undertaken to optimize their thermoelectric performance because understanding of the properties of this system had been limited due to its novelty. In this thesis, the thermoelectric performance of n-type Mg3Sb2−Mg3Bi2 alloys was systematically investigated and significantly improved. Thorough experimental characterization...

- Description:
- Soil-Machine Interaction (SMI) is ubiquitous on Earth and other planets. Over decades, ground-engaging equipment has been developed and widely used in various engineering applications, including civil construction, agriculture, terrestrial mobility, and even space exploration. However, systematic studies of SMI processes and the corresponding soil behavior are inadequate, which obstructs further...
