A ca. 273-261 Ma multi-component arc pluton in the southern area of the Beishan Orogenic Collage, NW China: a geochronological, geochemical, and petrogenetic analysis
(University of Waterloo, 2022-09-29)Along the southern edge of the Central Asian Orogenic Belt lies the Beishan Orogenic Collage, bridging the Tianshan Orogen (west) to the Mongolia-Xing’anling Orogen (east). The Beishan Orogenic Collage is thought to represent ... -
Cage-like Proteins as Bioink Components for 3D Bioprinting
(University of Waterloo, 2018-01-24)Hydrogel matrices have been used as structural surrogates in 3D bioprinting as a mechanism to provide the appropriate environment for cell adhesion and proliferation. In this research, the preparation and optimization of ... -
Calibrant Free Sampling and Enrichment with Solid-Phase Microextraction: Computational Simulation and Experimental Verification
(American Chemical Society, 2017-04-05)Despite the benefits of diffusion-based calibrant-free sampling based on solid-phase microextraction (SPME), this quantification approach is often underestimated due to an inadequate understanding of how extraction parameters ... -
Calibrating the Long-Range Backbone Dynamics of Polymers in Solution Using Two Different Models
(University of Waterloo, 2022-09-29)The fluorescence decays of a series of 41 pyrene-labeled poly(oligo(ethylene glycol)methyl ether methacrylate)s (Py-PEGnMA where n = 0, 1, 2, 3, 4, 5, 9, 16, 19) were prepared by free-radical polymerization of 1-pyrenebutyl ... -
Calibration and validation the Dynamic Photorefraction System (DPRS)
(University of Waterloo, 2014-09-25)Introduction: Our group has been measuring accommodation in myopic children. The instrument of choice has been the Power Refractor (Multichannel Systems). However, this instrumentation is no longer supported and runs on ... -
Calibration of a Lattice Model for High-Molecular-Weight Block Copolymer Melts
(AIP, 2019-05-06)The Morse calibration is applied to a lattice model designed for efficient simulations of two-component polymer melts of high molecular weight. The model allows multiple occupancy per site, which results in high invariant ... -
Calibration of the Flory-Huggins Interaction Parameter in Field-Theoretic Simulations
(2019)Field-theoretic simulations (FTS) offer a versatile method of dealing with complicated block copolymer systems, but unfortunately they struggle to cope with the level of fluctuations typical of experiments. Although the ... -
Calmodulin as a universal regulator of voltage gated calcium channels
(University of Waterloo, 2014-05-22)Calmodulin (CaM) is a ubiquitous calcium-binding protein responsible for the binding and activation of a vast number of enzymes and signaling pathways. It contains two lobes that bind two calcium ions each, separated by a ... -
Calmodulin Binding and Activation of Mammalian Nitric Oxide Synthases
(University of Waterloo, 2008-05-12)Calmodulin (CaM) is a ubiquitous cytosolic Ca2+-binding protein involved in the binding and regulation of more than three-hundred intracellular target proteins. CaM consists of two globular domains joined by a central ... -
Calmodulin regulates Cav3 T-type channels at their gating brake
(American Society for Biochemistry and Molecular Biology, 2017-12-08)Calcium (Cav1 and Cav2) and sodium channels possess homologous CaM-binding motifs, known as IQ motifs in their C termini, which associate with calmodulin (CaM), a universal calcium sensor. Cav3 T-type channels, which serve ... -
Can current models of accommodation and vergence predict accommodative behavior in myopic children?
(Elsevier, 2014-08)Investigations into the progression of myopia in children have long considered the role of accommodation as a cause and solution. Myopic children show high levels of accommodative adaptation, coupled with accommodative lag ... -
Can kynurenic acid cause myelin loss in chicken optic nerves?
(University of Waterloo, 2017-09-27)Kynurenic acid (KYNA) is one of many kynurenine intermediate products in the tryptophan metabolism pathway and has been shown to have neuro-activity. Previous work revealed that prolonged infusion of a high dose of KYNA ... -
Can Lensing Measure The Shape Of Dark Matter Halos?
(University of Waterloo, 2012-09-27)The aim of this project was to explore the shapes of dark matter halos using high resolution N-body simulations. One of the main aspects explored was how well the shape can be measured through weak lensing. To explore this, ... -
Canonical Structure and Conservation Laws of General Relativity on Null Surfaces and at Null Infinity
(University of Waterloo, 2021-01-12)The first part of this thesis addresses the canonical structure of general relativity on generic null surfaces. The pre-symplectic potential of metric general relativity, evaluated on a null surface, is decomposed into ... -
Capturing Plant Metabolome with Direct-Immersion in Vivo Solid Phase Microextraction of Plant Tissues
(American Chemical Society, 2015-12-15)For the first time, an in vivo sampling mode of direct immersion–solid phase microextraction (DI-SPME) was employed to capture the metabolome of living plant specimens, using apple (Malus × domestica Borkh.) as a model ... -
The carbon and nitrogen composition of suspended particulate matter in Lake Erie, selected tributaries, and its outflow
(University of Waterloo, 2005)Since their introduction to Lake Erie, dreissenid mussels may have reengineered the cycling of nutrients in the lake so that the nearshore benthic community intercepts, retains, and recycles greater quantities of nutrients. ... -
