Maximal cell density predictions for compressible polymer foams
(Elsevier, 2012-12-05)Thermodynamic upper bounds for polymer foam cell densities are predicted using compressible selfconsistent field theory. It is found that the incompressible limit always gives the highest, and therefore ultimate, upper ... -
Mean-Field Theory of Collective Behavior of Quantum Dipolar Rotors
(University of Waterloo, 2021-02-08)Motivated by the recent experimental measurements of the dielectric property of confined quantum dipolar molecules, the orientational dipolar ordering transition is investigated in the quantum generalization of the quantum ... -
THE MEASUREMENT OF INTER-PARTICLE DIFFUSION COEFFICIENTS IN MINE WASTES
(University of Waterloo, 2021-05-04)Acid mine drainage (AMD) is the release of acidic waters from mines, waste-rock piles and mine tailings impoundments containing high concentrations of SO4, Fe(II) and other metal(oid)s. The bulk of AMD generation occurs ... -
Measurement of Surface Tensions in Aggregated Cells of the Embryonic Chick
(University of Waterloo, 2008-01-23)Cell surface properties are crucial to the mechanisms by which groups of cells organize themselves during embryogenesis, cancer metastases and tissue engineering. Measured surface tension values provide a quantitative ... -
Measurement of Tensile Forces in Xenopus laevis Neural Tissue
(University of Waterloo, 2010-01-22)Neurulation is critical for the proper development of the central nervous system during embryogenesis. This process requires coordinated morphogenetic movements driven by localized cell movements. The key morphogenetic ... -
Measuring Entanglement Entropy in Valence Bond Quantum Monte Carlo Simulations
(University of Waterloo, 2010-12-08)In this thesis we examine methods for measuring entanglement entropy in spin-1/2 Heisenberg systems using quantum Monte Carlo in the valence bond basis. We begin by presenting the quantum Monte Carlo techniques used in ... -
Measuring Non-Markovianity of Noise in the Cenrtal Spin System
(University of Waterloo, 2019-05-24)In this thesis, we explore non-Markovian noise in the central spin system due to the coupling between the central spin and the environment. We use a solid state nuclear magnetic resonance system to do the experiment since ... -
Measuring Quantum Correlations of Polarization, Spatial Mode, and Energy-Time Entangled Photon Pairs.
(University of Waterloo, 2023-09-07)Optical quantum technologies have found applications in all facets of quantum information. Single photons are actively being researched for quantum computation, communication, and sensing, due to their robustness against ... -
Measuring the Environmental Dependence of Galaxy Haloes with Weak Lensing
(University of Waterloo, 2013-09-04)We investigate the uses of gravitational lensing for analysing the dark matter haloes around galaxies, comparing galaxies within groups and clusters to those in the field. We consider two cases: when only photometric ... -
Measuring Trapped Ion Qudits
(University of Waterloo, 2019-09-26)Quantum information has typically focused on using 2-level qubits to perform simulation and computation. We propose to expand the number of levels for computation using qudits, where \(d>2\). Doing so could be a viable ... -
Mechanisms controlling the recycling of nutrient silicon in freshwater sediments: An experimental study of the interactions between silicon, iron and phosphorus
(University of Waterloo, 2020-12-23)Dissolved silicon (DSi) is an essential nutrient for numerous terrestrial and aquatic organisms. In freshwater systems, including streams, rivers and lakes, an important class of siliceous algae are diatoms. Human activities, ... -
Mechanisms of DNA Sensing on Graphene Oxide
(American Chemical Society, 2013-08-20)Adsorption of a fluorophore-labeled DNA probe by graphene oxide (GO) produces a sensor that gives fluorescence enhancement in the presence of its complementary DNA (cDNA). While many important analytical applications have ... -
A mechanistic approach to assessment of the geochemical evolution of low sulfide mine-waste rock
(University of Waterloo, 2019-01-04)The potential for mine wastes to generate elevated concentrations of solutes including metals, sulfate, and reduced pH exists wherever mine-waste rock is stockpiled at the Earth’s surface representing one of the world’s ... -
A Mechanistic Derivation of The Monod Equation For Biofilm in Porous Media
(University of Waterloo, 2021-12-20)A mechanistic derivation of the Monod bioreaction equation is presented. The numerical model developed for this derivation involves four processes. 1)On the pore scale, substrate diffuses from the bulk aqueous phase crossing ... -
Mechanistic Role of ARNT/HIF-1β in the Regulation of Glucose-Stimulated Insulin Secretion
(University of Waterloo, 2014-04-29)Loss of glucose-stimulated insulin secretion (GSIS) from the pancreatic beta-cells is one of the earliest detectable defects in the pathogenesis of type 2 diabetes. However, despite its relevance, the mechanisms that govern ... -
Mechanistic studies on the effect of membrane lipid acyl chain composition on daptomycin pore formation
(Elsevier, 2018-11-01)Daptomycin is a lipopeptide antibiotic that binds and permeabilizes the cell membranes of Gram-positive bacteria. Membrane permeabilization requires both calcium and phosphatidylglycerol (PG) in the target membrane, and ... -
