Optimal sampling methods for modelling the occupancy of Arctic grayling (Thymallus arcticus) in the Canadian Barrenlands
(Canadian Science Publishing, 2017)In occupancy models, imperfect detectability of animals is usually corrected for by using temporally-repeated surveys to estimate probability of detection. Substituting spatial replicates for temporal replicates could be ... -
An investigation of low energy quasiparticle excitations via thermal transport measurements
(University of Waterloo, 2017-06-16)Thermal transport measurements can provide a unique perspective of the nature of a system by exploring the behaviour of the low energy excitations from the ground state. Delocalized quasiparticle excitations can affect ... -
Quantum critical responses via holographic models and conformal perturbation theory
(University of Waterloo, 2017-06-15)We investigate response functions near quantum critical points, allowing for finite temperature and a mild deformation by a relevant scalar. When the quantum critical point is described by a conformal field theory, we use ... -
Stereocoherence thresholds as a measure of global stereopsis
(University of Waterloo, 2017-06-14)Purpose: The purpose of this study was to develop a robust and reliable clinical test of stereopsis that is complementary to the conventional disparity threshold tests. Methods: Random dot stereograms containing ... -
Quantum Information Enabled Neutron Interferometry
(University of Waterloo, 2017-06-12)Neutron interferometry with its ability to encode and extract information provides a test bed for quantum mechanics and precise measurement of physical quantities of significant importance in physics. However, this ... -
Design Strategy of 2D Material Field-Effect Transistors: Engineering the Number of Layers in Phosphorene FETs
(AIP Publishing, 2016-06-07)Thickness or the number of layers in 2D semiconductors is a key parameter to determine the material’s electronic properties and the overall device performance of 2D material electronics. Here we discuss the engineering ... -
Quantum Gates and Decoupling in Qubits with Fixed Transverse Coupling
(University of Waterloo, 2017-05-25)Among all the quantum computer candidates, the superconducting system is one of the most convincing platforms due to its strong couplings and scalability. To be more specific, this thesis focuses on the superconducting ... -
Ra-228, Ra-226, Ra-224 and Ra-223 in potential sources and sinks of land-derived material in the German Bight of the North Sea: implications for the use of radium as a tracer
(Springer, 2011-08-01)Activities of the naturally occurring radium nuclides Ra-228, Ra-226, Ra-224 and Ra-223 were determined in waters of the open German Bight and adjacent nearshore areas in the North Sea, in order to explore the potential ... -
Worldwide retention of nutrient silicon by river damming: From sparse data set to global estimate
(American Geophysical Union, 2014-08-13)Damming of rivers represents a major anthropogenic perturbation of the hydrological cycle, with the potential to profoundly modify the availability of nutrient silicon (Si) in streams, lakes, and coastal areas. A global ... -
Dissolved inorganic carbon and alkalinity fluxes from coastal marine sediments: model estimates for different shelf environments and sensitivity to global change
(European Geosciences Union, 2013-01-24)We present a one-dimensional reactive transport model to estimate benthic fluxes of dissolved inorganic carbon (DIC) and alkalinity (AT) from coastal marine sediments. The model incorporates the transport processes of ... -
Structure of peat soils and implications for water storage, flow and solute transport: A review update for geochemists
(Elsevier, 2016-07-01)Global peatlands are a valuable but vulnerable resource. They represent a significant carbon and energy reservoir and play major roles in water and biogeochemical cycles. Peat soils are highly complex porous media with ... -
Plastic debris in the Laurentian Great Lakes: A review
(Elsevier, 2015-03-01)Pollution by plastic debris is an increasing environmental concern in the Laurentian Great Lakes where it affects open-water, shoreline, and benthic environments. Open-water surveys reveal that in certain areas of the Great ... -
Circulation and oxygen cycling in the Mediterranean Sea: Sensitivity to future climate change
(American Geophysical Union, 2016-11-12)Climate change is expected to increase temperatures and decrease precipitation in the Mediterranean Sea (MS) basin, causing substantial changes in the thermohaline circulation (THC) of both the Western Mediterranean Sea ... -
Two centuries of nitrogen dynamics: Legacy sources and sinks in the Mississippi and Susquehanna River Basins
(American Geophysical Union, 2017-01-07)Global flows of reactive nitrogen (N) have increased significantly over the last century in response to agricultural intensification and elevated levels of atmospheric deposition. Despite widespread implementation conservation ... -
Iron Isotope Fractionations Reveal a Finite Bioavailable Fe Pool for Structural Fe(III) Reduction in Nontronite
(American Chemical Society, 2017-08-16)We report on stable Fe isotope fractionation during microbial and chemical reduction of structural Fe(III) in nontronite NAu-1. Fe-56/Fe-54 fractionation factors between aqueous Fe(II) and structural Fe(III) ranged from ... -
Atmospheric acidification of mineral aerosols: a source of bioavailable phosphorus for the oceans
(European Geosciences Union, 2011-07-01)Primary productivity of continental and marine ecosystems is often limited or co-limited by phosphorus. Deposition of atmospheric aerosols provides the major external source of phosphorus to marine surface waters. However, ... -
Fate of Adsorbed U(VI) during Sulfidization of Lepidocrocite and Hematite
(American Chemical Society, 2017-02-21)The impact on U(VI) adsorbed to lepidocrocite (gamma-FeOOH) and hematite (alpha-Fe2O3) was assessed when exposed to aqueous sulfide (S(II)(aq)) at pH 8.0. With both minerals, competition between S(-II) and U(VI) for surface ... -
