Gauge Models of Topological Phases and Applications to Quantum Gravity
(University of Waterloo, 2018-06-26)In 2+1 dimensions, gravity is an SU(2) topological gauge theory that can be written as BF theory. In the condensed matter literature, the Hamiltonian realization of BF theory for finite groups is known as the Kitaev model. ... -
Gauge Theory Dynamics and Calabi-Yau Moduli
(University of Waterloo, 2014-07-02)We compute the exact partition function of two dimensional N=(2,2) supersymmetric gauge theories on S². For theories with SU(2|1)_A invariance, the partition function admits two equivalent representations corresponding to ... -
Gaze strategies for coping with glare under intense contra light viewing conditions – A pilot study
(University of Waterloo, 2011-09-30)Purpose: This is a pilot study to investigate gaze strategies for coping with glare when performing a simple visual task under intense contra light viewing conditions. Method: Twenty-four normally sighted participants ... -
Gem-Difluorination of α-Diazo Amides Using (Difluoroiodo)toluene
(University of Waterloo, 2017-09-25)Fluorination chemistry is a branch of study that appeals to the pharmaceutical and agricultural industries. Drawbacks of popular methods of forming carbon-fluorine bonds include high cost or hazardous conditions that are ... -
Generalized holographic dualities for metric gravity & Quantum geometry based on area variables
(University of Waterloo, 2020-09-18)Holography holds promise for simplifying computations in quantum gravity. In part I of this thesis, we construct holographic boundary theories for linearized gravity, for a general family of finite or quasi-local boundaries, ... -
Generating Functionals for Spin Foam Amplitudes
(University of Waterloo, 2014-09-25)Various approaches to Quantum Gravity such as Loop Quantum Gravity, Spin Foam Models and Tensor-Group Field theories use invariant tensors on a group, called intertwiners, as the basic building block of transition amplitudes. ... -
Generation of Short Laser Pulses by Using Hollow Fibre and Chirped Mirror Compressor System
(University of Waterloo, 2017-10-23)A FEMTOLASERS hollow core silicon fibre of length 1 m and 250μm inner diameter was set up in the lab in Waterloo with the purpose of generating sub 10fs pulses for Coulomb Explosion Imaging (CEI). The input laser was a new ... -
Generational Effects of Bisphenol A on Growth and Stress Performance in Rainbow Trout
(University of Waterloo, 2014-06-25)The aquatic environment is severely impacted by xenobiotics that are released due to anthropogenic activities, threatening ecosystem health. Some of these contaminants accumulate in lipophilic fish tissues and are maternally ... -
Genesis of a giant Paleoproterozoic strata-bound magnesite deposit: Constraints from Mg isotopes
(Elsevier, 2016-08-01)Giant strata-bound magnesite deposits are absent in modern and most Phanerozoic sedimentary environments but occur predominantly in Precambrian strata. These deposits may have formed directly through precipitation of evolved ... -
The Genetic Analysis of Autophagy-Dependent Caspase Activation in Drosophila melanogaster
(University of Waterloo, 2009-10-23)During Drosophila melanogaster pupation, groups of undifferentiated adult cells proliferate and undergo regulated cell shape changes, while larval tissues are eliminated by programmed cell death (PCD). PCD is most commonly ... -
Genome analysis reveals unexpected absence of oxygen metabolic capacity in helminths
(University of Waterloo, 2022-07-06)Oxygen metabolism in parasitic helminths differs significantly from that of most aerobic eukaryotes, as these organisms must be able to switch between aerobic and anaerobic metabolisms depending on their life-cycle stage. ... -
A genomic study of the invasive red alga Bangia atropurpurea (Mertens ex Roth) C. Agardh
(University of Waterloo, 2022-04-13)The phylum Rhodophyta comprises the red algae, which are morphologically diverse organisms present in marine and freshwater environments. The red algae order, Bangiales, is an ancient lineage and molecular studies have ... -
The genus Solidago L. (Astereae, Asteraceae) in South America and related taxa in North America
(University of Waterloo, 2009-05-14)The goldenrod genus Solidago L. is one of the larger genera in the flowering plant family Asteraceae. The genus is primarily North American and was recently revised in Flora of North America. In contrast, Solidago in South ... -
Geochemical and microbiological characterization of effluent and pore water from low-sulfide content waste rock
(University of Waterloo, 2013-04-22)Laboratory and field studies were completed to characterize the geochemistry and microbiology of drainage emanating from low-S content waste-rock test piles at the Diavik Diamond Mine (Diavik) from 2007 through 2010. The ... -
Geochemical and Microbiological Characterization of the Historic Waste Rock Piles at the Detour Lake Gold Mine
(University of Waterloo, 2016-09-16)Four of the historic waste rock stockpiles (WRS #1-#4) at the Detour Lake mine site were studied to determine the potential for generation of acid rock drainage (ARD). The stockpiles were constructed during the original ... -
Geochemical Characterization and Assessment of Stabilization Mechanisms for Mercury-Contaminated Riverbank Sediments from the South River, Virginia (USA)
(University of Waterloo, 2013-04-29)Elevated concentrations of mercury (Hg) in aquatic systems can be a threat to ecosystems and human health. Mercury-bearing sediment particles from eroding riverbanks can be an ongoing source of bioavailable Hg to aquatic ... -
