Advancing Techniques for Detecting Dwarf Satellite Populations Beyond the Local Group
(University of Waterloo, 2022-05-20)This thesis includes material from three papers that develop techniques for quantifying faint dwarf satellite populations outside the Local Group. Dwarf satellites are important for our understanding of small-scale structure ... -
Advancing the robustness of polarization and time bin quantum key distribution for free-space channels
(University of Waterloo, 2023-05-15)Quantum networks are an emerging technology that aims to harness the power of quantum mechanics to revolutionize communication and computation. Many countries are establishing national quantum networks to modernizing their ... -
Adventures in Holography
(University of Waterloo, 2014-07-11)In this thesis, inspired by the holographic theories, we study a variety of interesting problems in gravity, condensed matter and cosmology. First, we explore the entanglement entropy of a general region in a theory of ... -
Age Determination and Growth of Rainbow Darter (Etheostoma caeruleum) in the Grand River, Ontario
(University of Waterloo, 2016-05-31)The accurate determination and validation of age is an important tool in fisheries management. Age profiles allow insight into population dynamics, mortality rates and growth rates, which are important factors in many ... -
Aggregation of Amyotrophic Lateral Sclerosis-Associated Cu/Zn Superoxide Dismutase
(University of Waterloo, 2010-05-21)Amyotrophic lateral sclerosis (ALS) is a devastating, progressive, and fatal neurodegenerative disease. Despite the fact that ALS is the most common motor neuron disease in adulthood, there is no effective treatment for ... -
Aging affects circadian clock and metabolism and modulates timing of medication
(Elsevier, 2021-04)Aging is associated with impairments in the circadian rhythms, and with energy deregulation that affects multiple metabolic pathways. The goal of this study is to unravel the complex interactions among aging, metabolism, ... -
Agreement in dry eye management between optometrists and general practitioners in primary health care in the Netherlands
(Elsevier, 2015-04-18)Purpose: To investigate the agreement in dry eye care management between general practitioners (GPs) and optometrists in the Netherlands. Methods: A web-based survey was used to investigate the agreement in symptoms ... -
Algorithms for quantum molecular dynamics: from matrix product states to path integrals
(University of Waterloo, 2021-01-13)This thesis describes several novel approaches in quantum molecular dynamics for obtaining properties of molecular systems in different regimes. We investigate ground state properties of chains of linear rotors with ... -
An ALMA View of Molecular Gas in Brightest Cluster Galaxies
(University of Waterloo, 2018-09-25)In this thesis I use ALMA observations to map the distribution and kinematics of molecular gas in the brightest cluster galaxies of three galaxy clusters: 2A0335+096, RXJ0821+0752, and RXCJ1504-0248. The goal is to understand ... -
Alterations in Colorectal Cancer Cell-extracellular Matrix Interactions Upon Acquisition of Chemotherapy Resistance.
(University of Waterloo, 2015-12-16)Adjuvant chemotherapy is an essential component in the treatment of advanced colorectal cancer (CRC). Unfortunately, many patients experience recurrence with aggressive, chemotherapy-resistant disease for which the prognosis ... -
An alternative derivation of orbital-free density functional theory
(AIP, 2019-05-28)Polymer self-consistent field theory techniques are used to derive quantum density functional theory without the use of the theorems of density functional theory. Instead, a free energy is obtained from a partition function ... -
Alternative splicing of Lymnaea Cav3 and NALCN ion channel genes serves to alter biophysical properties, membrane expression, and ion selectivity
(University of Waterloo, 2012-08-30)Evidence is presented that Lymnaea contains homologues for mammalian Cav3 and NALCN 4-domain ion channels, which retain key amino acid sequence motifs that differentiate these channels from other 4-domain types. Molecular ... -
Aluminium-Palladium Transition Edge Sensors
(University of Waterloo, 2008-09-15)A superconducting Transition Edge Sensor (TES) can be used to make the most sensitive thermometer which operates in a very narrow temperature range. The thin film bi-layer fabrication details are discussed as well as ... -
Amelioration of Plant Drought Stress by Plant Growth-Promoting Bacteria
(University of Waterloo, 2017-04-28)Plant growth-promoting bacteria (PGPB) that contain the enzyme (1-aminocyclopropane-1-carboxylate) ACC deaminase protect a variety of plants against damage from various biotic and abiotic stresses. Here, the ability of ... -
Amended Model of Large Scale Dark Matter Structure
(University of Waterloo, 2020-09-03)Dark matter makes up around a quarter of the total energy density in the universe, but its identity remains elusive. Current ways of studying dark matter have centered around its macroscopic properties, such as density ... -
Ammonia-oxidizing archaea and complete ammonia-oxidizing bacteria in a municipal wastewater treatment plant
(University of Waterloo, 2018-09-25)High levels of ammonia in aquatic environments can lead to eutrophication, oxygen depletion, and toxicity to aquatic animals. An important goal of municipal wastewater treatment plants (WWTPs) is to remove ammonia from ... -
Ammonia-oxidizing archaea in engineered biofiltration systems
(University of Waterloo, 2016-12-21)Ammonia is a nitrogenous metabolic waste product that is produced by all animal life. High concentrations of ammonia are toxic to animals and may result in algal blooms and eutrophication in aquatic environments. To prevent ... -
Ammonium Attenuation and Nitrogen Dynamics in Groundwater Impacted By a Poultry Manure Lagoon
