Achievable Polarization for Heat-Bath Algorithmic Cooling
(University of Waterloo, 2015-08-17)Highly pure quantum states play a central role in applications of quantum information science, both as initial states for quantum algorithms and as resources for quantum error correction. Controlled preparation of pure ... -
Action Mechanism and Structural Studies on the Lipopeptide Antibiotic Daptomycin
(University of Waterloo, 2019-07-02)Daptomycin (dap) is calcium-dependent lipopeptide antibiotic that is used clinically to treat systemic infections caused by Gram-positive pathogens. It is thought that dap brings about its antimicrobial effect by binding ... -
The action mechanism of daptomycin
(Elsevier, 2016-12-15)Daptomycin is a lipopeptide antibiotic produced by the soil bacterium Streptomyces roseosporus that is clinically used to treat severe infections with Gram-positive bacteria. In this review, we discuss the mode of action ... -
An Acyl-Linked Dimer of Daptomycin Is Strongly Inhibited by the Bacterial Cell Wall
(American Chemical Society, 2017-03-28)The lipopeptide antibiotic daptomycin is active against Gram-positive pathogens. It permeabilizes bacterial cell membranes, which involves the formation of membrane-associated oligomers. We here studied a dimer of daptomycin ... -
Adaptation to near addition lenses - Effect of AV/A ratio and age
(University of Waterloo, 2007-05-17)AIM: The primary purpose of this thesis was to evaluate the pattern of changes to accommodation and phoria when pre-presbyopic individuals perform near work for 20 minutes with +2D lenses. In addition, the thesis also ... -
The adaptive elements of disparity vergence: Dynamics and directional asymmetries.
(University of Waterloo, 2018-04-24)Vergence eye movements alter the angle between the two visual axes, creating changes in binocular fixation distance. They are primarily stimulated by retinal image disparities, but can also be driven by inputs from ocular ... -
