Extreme Temperature Events Caused by Climate Change and Variability: Drivers and Its Impact
(2023-05-01)
This dissertation investigates extreme temperature events, their drivers, and their impact on society across three main sections. As the climate warms, understanding these events and their consequences becomes increasingly ...
Spectroscopic Investigation of Premixed H2/NH3/N2-Air Flames Stabilized on a H2-Air Pilot Flame
(2023-05-10)
Given that burning conventional hydrocarbon fuels produces harmful carbon-based emissions contributing to global warming, recent environmental initiatives have focused on removing carbon-based fuels from the transportation, ...
Multivariable Time-frequency Stabilization and Tracking of 4-DOF Underactuated Surface Vessels
(2023-05-03)
Underactuated mechanical systems (UMS) represent a significant group of mechanical systems with fewer independent control actuators than degrees of freedom (DOF). These systems are considered more efficient and lightweight ...
Mental Health Disparities Among Adolescents and Young Adults in the United States
(2023-04-10)
Using data from the National Survey on Drug Use and Health from 2010 to 2020, this doctoral dissertation studies the national mental health (MH) crisis and disparities among US adolescents and young adults.
Chapter one ...
On Left-Invariant Rank 2 Distributions with Zero Generalized Wilczynski Invariants on 6-Dimensional Lie Groups
(2023-04-18)
The thesis is devoted to the study of the fundamental system of invariants of bracket-generating rank 2 distributions, i.e. fields of planes, on n-dimensional manifolds (shortly, (2, n)-distributions). Distributions are ...
Evolution of an Effector Family and Changes in Host Interaction Repertoires
(2023-05-04)
Previously our lab described a 21-member gene family of the rice blast fungus Pyricularia oryzae that were named host-adapted genes (HAGs). Most AVR/effector genes of P. oryzae are either unique or have few paralogs. The ...
A Study of Compression Methods and Their Applications to Large Geological Models
(2023-04-13)
The promise of deep learning is to discover rich hierarchical structure of the data that allows to circumvent manual feature extraction and engineering. In this study, we explore novel applications of the deep learning, ...
Efficient Computation of Boundary-Layer Instabilities in Highly Three-Dimensional Flows
(2023-04-21)
Boundary-layer transition from laminar to turbulent flow critically affects vehicle safety and performance, particularly at hypersonic speeds where heat-transfer rates are extreme. Accounting for transition effects requires ...
Assessing Ecosystem Service Benefits of Improved Soil Management Practices at the Field and Watershed Scales
(2023-04-21)
Poor soil management limits the soil functions of water infiltration and storage and enhances water and soil losses. Amidst recurring droughts and declining water availability, improved soil management practices such as ...
Drug Reinforcement Impairs Cognitive Flexibility by Inhibiting Striatal Cholinergic Interneurons
(2023-05-03)
Addictive drugs, including illegal ones like cocaine and heroin, and prescription ones like opioids and benzodiazepines, produce strong cravings. Addiction is a chronic condition that affects behavior, brain function, and ...
