We investigate the microscopic nature of charge-carrier conduction in nanoscale semiconducting materials using time-resolved terahertz spectroscopy (TRTS). TRTS uses picosecond pulses of terahertz radiation (0.5-2.5 THz) to explore photoexcited charge-carrier lifetimes and dynamics with...

Patients with atrial fibrillation (AF) and ischemic stroke are at high risk for stroke recurrence. Early anticoagulation may reduce the risk of recurrent events but is usually avoided due to the risk of hemorrhagic transformation (HT). The risk of HT is based on historical data from an older...

Timing of Mask Fitting as a Predictor of Adherence in Children Requiring Non-Invasive Ventilation Therapy
DownloadFall 2024
Introduction: The utilization of non-invasive ventilation (NIV) in the pediatric population is becoming increasingly prevalent. NIV is a form of breathing support that employs a mask interface outside the airway. It provides necessary respiratory support that improves patients’ quality of life by...

Tiny Object Detection in Remote Sensing Images: End-to-End Super-Resolution and Object Detection with Deep Learning
DownloadFall 2020
In this thesis, we study the problem of detecting small objects on low-resolution (LR) satellite imagery. Small-object detection is a challenging problem, especially from LR images. To tackle the challenge, we propose a method to generate super-resolution images from low-resolution images and...

TiO2 Nanotube Arrays with Engineered Geometries: Growth, Characterization and Study of Selected Interfaces
DownloadSpring 2016
Titanium dioxide (TiO2) is a wide band gap, robust, n-type semiconductor whose transformation into vertically-oriented nanotube arrays makes them suitable electron percolation pathways for vectorial charge transfer togerther with high surface area. Growth of self-organized TiO2 nanotube arrays as...
