O antigen biosynthesis in Gram-negative bacteria: Characterization of alpha1,4-glucosyltransferase WclY from Escherichia coli O117 and development of glycosyltransferase inhibitors.
Gram-negative bacteria have a polysaccharide coat (O antigen) consisting of repeating units of oligosaccharides that is assembled by glycosyltransferases. Many of these bacteria are associated with disease, and the ... -
Obesity and Endothelial Function: Investigating the Importance of the Shear Stress Stimulus Profile Used for FMD Assessment
(2014-10-01)Endothelial function is important for the maintenance of vascular health and it can be assessed by measuring endothelial dependent flow mediated dilation (FMD) in response to an imposed increase in shear stress (SS). While ... -
Obituarizing Michael Jackson: Subject Formation through Material Cultural Branding
(2010-09-09)Historically, obituaries were created as news items and published in print media with the intentions of informing an audience of public hangings or similar sensational deaths. Over the years, obituaries changed in form to ... -
Object Class Recognition using Global Shape Descriptors in 3D
(2014-07-22)We formulate Global Shape Descriptors for object classifi cation in range data. The goal of object class recognition is to identify and localize objects of interest in a 3D point cloud.This work focuses on the automatic ... -
Object Recognition by Registration of Repeatable 3D Interest Segments
(2015-02-04)3D object recognition using depth data remains a difficult problem in computer vision. In this thesis, an object recognition system based on registering repeatable 3D surface segments, termed recognition by registration ... -
Object substitution masking reveals the continuous nature of conscious object representation
(2015-10-13)How the visual system resolves conflicting information in the construction of a stable and coherent conscious experience remains one of the central problems of vision science. One striking example of this resolution of ... -
Objective Assessment of Dysarthric Speech Intelligibility
(2011-09-28)The de-facto standard for dysarthric intelligibility assessment is a subjective intelligibility test, performed by an expert. Subjective tests are often costly, biased and inconsistent because of their perceptual nature. ... -
The Objective/Subjective Distinction of the Self: Examining Self-Discrepancy
(2014-09-08)Self-discrepancies have traditionally been measured with the Selves Questionnaire. This is an objective measure, in that it does not assume that individuals are aware of the discrepancies between their various self-state ... -
Objectively measured active transportation among 10-13 year olds from Kingston, Ontario
Background: Active transportation positively influences the physical and mental health of children and adolescents. Research on active transportation to school suggests that the walkability of the built environment can ... -

An Observational Study Examining the Association Between Chronic Pain Coping Strategies and Unplanned Health Care Use by Individuals Attending an Interdisciplinary Pain Clinic
Objective: To characterize a chronic pain clinic population and determine whether specific coping strategies were associated with an unplanned health care visit(s) after controlling for predisposing, enabling, and need ... -
Obstructions to Motion Planning by the Continuation Method
(2013-01-03)The subject of this thesis is the motion planning algorithm known as the continuation method. To solve motion planning problems, the continuation method proceeds by lifting curves in state space to curves in control space; ... -
Obtaining a quality model for manufacturing systems and establishing a maintenance-quality link
(2008-06-25)This thesis describes the application of the stochastic-flow-modeling (SFM) approach to represent the quality behavior of a manufacturing system. Initially, a simple, one-product type SFM is discussed and then a more ... -
Obtaining the Best Model Predictions and Parameter Estimates Using Limited Data
(2011-09-27)Engineers who develop fundamental models for chemical processes are often unable to estimate all of the model parameters due to problems with parameter identifiability and estimability. The literature concerning these two ... -
