A Highly Active RNA-Cleaving DNAzyme with Accelerated Activity by Ethanol and by Freezing
(University of Waterloo, 2018-04-27)DNAzymes are functional DNA molecules with catalytic activities. The EtNa is an example of a RNA-cleaving DNAzyme that catalyzes the cleavage reaction of a phosphodiester bond in the presence of metal ions, such as Na+ or ... -
A highly specific sodium aptamer probed by 2-aminopurine for robust Na+ sensing
(Oxford University Press, 2016-09-20)Sodium is one of the most abundant metals in the environment and in biology, playing critical ecological and physiological roles. Na+ is also the most common buffer salt for nucleic acids research, while its specific ... -
Hillock-free and atomically smooth InSb QWs grown on GaAs substrates by MBE
(Elsevier, 2019-05-01)Comprehensive studies on the surface morphological evolution of AlInSb metamorphic buffers and InSb QWs grown on top were conducted as a function of the GaAs (0 0 1) substrate offcut angles. We confirmed our earlier ... -
Historical overview of imaging the meibomian glands
(Elsevier, 2013-01)Growing knowledge of the role of the meibomian glands in dry eye disease and contact lens discomfort has resulted in a surge of interest in visualizing these glands within the eyelids. This manuscript provides an overview ... -
Historical Trends in Water Quality in the Grand River, Ontario: Reconstruction of Phosphorus Loadings
(University of Waterloo, 2014-01-29)Phosphorus, a mineral nutrient, is an essential element in aquatic systems. It is only available for biological activity in the form of orthophosphate and soluble restrictive phosphate. Eutrophication, caused by nutrient ... -
Historical trends of polychlorinated dibenzo-p-dioxins and dibenzofurans in fish and sediment associated with two bleached kraft pulp mills in northern Ontario.
(University of Waterloo, 2013-12-11)In the early 1990s polychlorinated dibenzo-p-dioxin (PCDD) and dibenzofuran (PCDF) contamination of fish was widely associated with bleached kraft pulp mills. Regulations were put into place in Canada and elsewhere to ... -
Hodge Theory for Geometrically Frustrated Magnetism
(University of Waterloo, 2022-09-29)We present an analytical formalism based on the concept of discrete differential forms and Hodge theory as a framework for understanding geometrically frustrated magnetism. The primary insight is to treat spins as a 1-form ... -
Holographic Correspondence and Exploring New Regimes of AdS/CFT Duality
(University of Waterloo, 2013-06-21)We aim to have a comprehensive understanding of holographic correspondence and to demonstrate how the holographic correspondence (or renormalization) can be applied. Thus this thesis is divided into two parts. The first ... -
Holographic Entanglement Entropy: RG Flows and Singular Surfaces
(University of Waterloo, 2012-08-23)Over the past decade, the AdS/CFT correspondence has proven to be a remarkable tool to study various properties of strongly coupled field theories. In the context of the holography, Ryu and Takayanagi have proposed an ... -
Holographic Experiments on Defects
(University of Waterloo, 2009-09-03)Using the AdS/CFT correspondence, we study the anisotropic transport properties of both supersymmetric and non-supersymmetric matter fields on (2+1)-dimensional defects coupled to a (3+1)-dimensional N=4 SYM "heat bath". ... -
Holographic Optical Manipulation of Trapped Ions for Quantum Simulation
(University of Waterloo, 2019-09-26)Trapped ion is one of the leading platforms for quantum simulation experiment due to its long coherence time and high fidelity state initialization, detection, and manipulation. To individually address ions at a single-ion ... -
Holographic studies of thermal gauge theories with flavour
(University of Waterloo, 2007-09-12)The AdS/CFT correspondence and its extensions to more general gauge/gravity dualities have provided a powerful framework for the study of strongly coupled gauge theories. This thesis explores properties of a large class ... -
Holography with a neutron interferometer
(The Optical Society, 2016-10-03)We use a Mach-Zehnder interferometer to perform neutron holography of a spiral phase plate. The object beam passes through a spiral phase plate, acquiring the phase twist characteristic of orbital angular momentum states. ... -
Horizon Thermodynamics from Einstein's Equation of State
(University of Waterloo, 2017-04-28)The striking resemblance between geometric theories of gravity and thermodynamics suggests a more fundamental relationship between the two seemingly distinct theories. It has been postulated that the radial Einstein ... -
The HOTHEAD Protein: Assessing Enzymatic Activity using Computational and Recombinant Protein Expression Approaches
(University of Waterloo, 2019-04-30)In Arabidopsis thaliana, a number of genes regulating cuticle synthesis have been identified by virtue of organ fusion phenotype. One such gene, HOTHEAD (HTH) was among those originally identified by this phenotype but its ... -
How a dry year affects spatial variability of ground thaw and changes the hydrology of a small Arctic watershed
(University of Waterloo, 2023-09-28)The summer of 2021 in the Inuvik area, NWT was warm and dry. As recorded in Siksik Creek, a sub-catchment of Trail Valley Creek located 50 km north-east of Inuvik, this was the 7th warmest summer and driest July recorded ... -
How are molecular crowding and the spatial organization of a biopolymer interrelated
(Royal Society of Chemistry, 2016-10-21)In a crowded cellular interior, dissolved biomolecules or crowders exert excluded volume effects on other biomolecules, which in turn control various processes including protein aggregation and chromosome organization. As ... -
How Hot Are Your Ions in Differential Mobility Spectrometry?
(American Chemical Society, 2020-01)Ions can experience significant field-induced heating in a differential mobility cell. To investigate this phenomenon, the fragmentation of several para-substituted benzylpyridinium “thermometer” ions (R = OMe, Me, F, Cl, ... -
HS-SPME-GC-TOFMS Methodology for Verification of Geographical Origin and Authenticity Attributes of Coffee Samples
(University of Waterloo, 2008-02-05)Increasing consumer awareness of food safety issues requires the development of highly sophisticated techniques for the authentication of food commodities. The food products targeted for falsification are either products ... -
Human Steroid Sulfatase: Inhibitor Studies and Photoaffinity Labeling
