Emergence and Spread of the SARS-CoV-2 Omicron Variant in Alberta Communities Revealed by Wastewater Monitoring
(medRxiv, 2022-10-03)Wastewater monitoring of SARS-CoV-2 allows for early detection and monitoring of COVID-19 burden in communities and can track specific variants of concern. Targeted assays enabled relative proportions of SARS-CoV-2 Omicron ... -
EMG-based simultaneous and proportional estimation of wrist/hand kinematics in uni-lateral trans-radial amputees
(BioMed Central, 2012-06-28)We propose a method for estimating wrist kinematics during dynamic wrist contractions from multi-channel surface electromyography (EMG). The algorithm extracts features from the surface EMG and uses dedicated multi-layer ... -
Emotional Encoding Context Leads to Memory Bias in Individuals with High Anxiety
(MDPI, 2018-01)We investigated whether anxious individuals, who adopt an inherently negative mindset, demonstrate a particularly salient memory bias for words tainted by negative contexts. To this end, sequentially presented target words, ... -
Emotional modulation of attention orienting by gaze varies with dynamic cue sequence
(Taylor & Francis, 2015-07-03)Recent gaze cueing studies using dynamic cue sequences have reported increased attention orienting by gaze with faces expressing fear, surprise or anger. Here, we investigated whether the type of dynamic cue sequence used ... -
An Empirical Investigation to Understand the Difficulties and Challenges of Software Modellers When Using Modelling Tools
(ACM, 2018-10)Software modelling is a challenging and error-prone task. Existing Model-Driven Engineering (MDE) tools provide modellers with little aid, partly because tool providers have not investigated users' difficulties through ... -
Empirical validation of the Gamification User Types Hexad scale in English and Spanish
(Elsevier, 2018-10-13)Gamification, the use of game elements in non-game systems, is now established as a relevant research field in human-computer interaction (HCI). Several empirical studies have shown that gameful interventions can increase ... -
Empirical Valuation of Watershed Services: A Spatial Instrumental Variable Regression Model of Treatment Plants in Canada
(University of Waterloo, 2023-05-14)We investigate the impact of forest cover on drinking water treatment costs in Canada using the 2015 Survey of Drinking Water Plants (SDWP). We estimate proportion of forest, urban, and agricultural land cover in the sub-sub ... -
(En)activist Drag: Kings reflect on Queerness, Queens, and Questionable Masculinities
(Taylor & Francis, 2016-07-20)In recent years, media attention to drag performers has increased transforming the once-hidden leisure activity of gay men and lesbians into a publicly recognized phenomenon. Many of these representations of drag have ... -
Encapsulation and controlled release of vitamin C in modified cellulose nanocrystal/chitosan nanocapsules
(Elsevier, 2021)Vitamin C (VC), widely used in food, pharmaceutical and cosmetic products, is susceptible to degradation, and new formulations are necessary to maintain its stability. To address this challenge, VC encapsulation was achieved ... -
Endocrine Disruptor Impacts on Fish From Chile: The Influence of Wastewaters
(Frontiers, 2021-03-25)Industrial wastewaters and urban discharges contain complex mixtures of chemicals capable of impacting reproductive performance in freshwater fish, called endocrine-disrupting compounds (EDCs). In Chile, the issue was ... -
Endocrine Regulation of Phosphate Homeostasis
(Elsevier, 2018)Phosphate, a component of nucleic acids, DNA and RNA, is incorporated in the structure of phospholipids in cell membranes, and is involved in many biological functions such as cell signaling, energy metabolism, and bone ... -
Energy Consumption Analysis of XRP Validator
(2020)The XRP Ledger is an open-source payment system with a primary focus on providing an efficient cross-border payment network. The network achieves distributed consensus and prevents double-spending all while remaining ... -
Engaging Children About Online Privacy Through Storytelling in an Interactive Comic
(Scienceopen, 2017-07)Children’s privacy is put at risk through online sharing of location-based information. We study the effectiveness of an educational interactive comic on improving 11- to 13-year-old children’s privacy knowledge and behaviour ... -
Engaging older adults in healthcare research and planning: a realist synthesis
(BioMed Central, 2016-12-01)Background The importance of engaging the community in healthcare research and planning has been widely recognized. Currently however, there is a limited focus on older adults, Canada’s fastest growing segment of the ... -
Enhanced photo-stability of inverted organic solar cells via using polyethylenimine in the electron extraction layers
(Elsevier, 2019-10)The influence of using Polyethylenimine (PEI) in the electron extraction layers (EELs) on the photo-stability of inverted organic solar cells (OSCs) is investigated. Results show that introducing PEI in the commonly used ... -
Enhanced photocatalytic oxidation of SO2 on TiO2 surface by Na2CO3 modification
(Elsevier, 2018-10-15)The effects of Na2CO3 on the photocatalytic oxidation (PCO) of SO2 with UV irradiated TiO2 (P25) were studied using a fixed bed reactor. Na2CO3 was loaded onto P25 using a wet coating method. The PCO efficiency for SO2 ... -
Enriched mixed finite element models for dynamic analysis of continuous and fractured porous media
(Elsevier, 2019-01-01)Enriched Finite Element Models are presented to more accurately investigate the transient and wave propagation responses of continuous and fractured porous media based on mixture theory. Firstly, the Generalized Finite ... -
Entangling qubit registers via many-body states of ultracold atoms
(American Physical Society, 2016-04-25)Inspired by the experimental measurement of the Rényi entanglement entropy in a lattice of ultracold atoms by Islam et al. [Nature (London) 528, 77 (2015)], we propose a method to entangle two spatially separated qubits ... -
Entropic Matroids and Their Representation
(Multidisciplinary Digital Publishing Institute, 2019)This paper investigates entropic matroids, that is, matroids whose rank function is given as the Shannon entropy of random variables. In particular, we consider p-entropic matroids, for which the random variables each have ... -
Entropic segregation of short polymers to the surface of a polydisperse melt
(Springer, 2017)Chain ends are known to have an entropic preference for the surface of a polymer melt, which in turn is expected to cause the short chains of a polydisperse melt to segregate to the surface. Here, we examine this entropic ...
