Forensic electrochemistry: time since deposition (TSD) estimation of degrading bloodstains using differential pulse voltammetry
(2021-12-01)Methods for bloodstain time since deposition (TSD) estimation are still in development. Hemoglobin (Hb) oxidative changes remain one of the primary means of bloodstain aging. This research explores the use of differential ... -
Characterizing blood plasma proteins from organ tissue in rainbow trout (Oncorhynchus mykiss) using a non-targeted proteomics approach
(2021-12-01)Protein expression patterns adapt to various cues to meet the needs of an organism. The dynamicity of an organism’s proteome can therefore reveal information about an organism’s health. Proteome databases contain limited ... -
Immunomodulatory activity of Lacticaseibacillus rhamnosus R0011: analysis of secretome-mediated impacts on innate immune outcomes in intestinal epithelial cells and antigen presenting cells
(2021-12-01)Certain lactic acid bacteria (LAB), such as Lacticaseibacillus rhamnosus R0011, are associated with immune modulatory activities including down-regulation of pro-inflammatory gene transcription and expression. While host ... -
Automatic knobs-tuning for DB2 using deep reinforcement learning
(2021-12-01)Modern database management systems have hundreds of different configuration parameters (knobs) that control various aspects of how they behave and perform. These knobs must be properly tuned in order to maximize the ... -
The Role of Interactive Visualization in Fostering Trust in AI
(IEEE, 2021-12-10)The increasing use of artificial intelligence (AI) technologies across application domains has prompted our society to pay closer attention to AI's trustworthiness, fairness, interpretability, and accountability. In order ... -
Modelling calcite dissolution in a rotating disc reaction vessel
(2021-06-01)The carbonate system is ubiquitous in nature, playing a role in many natural and industrial processes. For calcite dissolution, the kinetics and mass transport of the dissolved species reflect both the chemistry of the ... -
Assessing the influence of geological and land-use gradients on zooplankton and phytoplankton biodiversity in the land between ecotone
(2021-11-01)The Land Between (TLB) is an ecotone in south-central Ontario that represents a transition from limestone-dominated bedrock to granite-dominated bedrock, creating notable calcium and land-use gradients across this unique ... -
A modular interface framework for multimodal annotations and visualizations in Human-AI collaboration
(2021-07-01)Modular is a web-based annotation, visualization, and inference software plat-form for computational language and vision research. The platform enables researchers to set up an interface for efficiently annotating language ... -
Implicit gaze interaction for information visualization
(2021-08-01)This thesis presents a novel marker-free method for identifying screens of interest when using head-mounted eye-tracking for visualization in cluttered and multi-screen environments. The presented approach offers a solution ... -
Empirically detecting colour: can we use solar cells as colour sensors?
(2021-08-01)The purpose of this thesis was to explore the possibility of using solar cells as a colour sensor. Colour sensors already exist, yet they are either costly or fail at correctly sensing monochromatic light. Our experiment ... -
Monolayer terpyridyl metal complexes for high-efficiency electrochromic materials
(2021-08-01)Electrochromic materials (ECMs) can change their color with changes of applied electrochemical potential. Currently, the use of ECMs in the industry is limited to mainly inorganic metal oxides, conjugated conducting polymers, ... -
Refining adverse outcome pathways using Japanese Medaka Embryos (Oryzias latipes) exposed to 2,3,7,8-Tetrachlorodibenzodioxin
(2021-08-01)Adverse outcome pathways (AOPs) are a framework that categorizes the impact of chemicals biologically from the initial molecular interaction through to the ecosystem level. This research aims to refine two existing AOPs ... -
Determining the effects of harmful algae blooms and their toxins on fish from both environment and laboratory-based studies through the use of proteomics
(2021-01-01)The effects of harmful algae blooms (HABs) on wild, freshwater, large-bodied fish have been under examined. Blood samples were collected from fish in Hamilton Harbor and Lake Erie to assess the effects of HABs on a molecular ... -
A deep learning approach to focal cortical dysplasia segmentation in children with medically intractable epilepsy
(2021-08-01)Paediatric epilepsy is one of the most common neurological disorders and has major impact on the cognition and quality of life of children. Focal Cortical Dysplasia (FCD) is one of the most common causes of medically ... -
Conductive Si doped metal oxide fuel cell catalyst supports: understanding the role of Si content
(2021-08-01)Current proton exchange membrane fuel cell (PEMFC) catalysts commonly use platinum supported on carbon (Pt/C) which is susceptible to corrosion, thus a highly conductive and stable Ti3O5 doped by Si (TOS) conductive metal ... -
SegmentPerturb: effective black-box hidden voice attack on commercial ASR systems via selective deletion
(2021-08-01)Voice control systems continue becoming more pervasive as they are deployed in mobile phones, smart home devices, automobiles, etc. Commonly, voice control systems have high privileges on the device, such as making a call ... -
Simulating a virtual drilling task using audio, visual, and mouse movement cues during the COVID-19 pandemic
