G-Quadruplex DNA for Fluorescent and Colorimetric Detection of Thallium(I)
(American Chemical Society, 2016-02-26)Thallium is a highly toxic heavy metal, but its 495 nm FRET sensing is underexplored compared to its neighboring elements Blue in the periodic table: lead and mercury. Thallium has two " oxidation states. A DNAzyme-based ... -
Game play in virtual reality driving simulation involving head-mounted display and comparison to desktop display
(Springer, 2019-11-28)Previous studies have reported the effect of driving simulator games on simulator sickness and eye symptoms experienced by users; however, empirical results regarding the game experience using commercial virtual reality ... -
The Gamification User Types Hexad Scale
(ACM, 2016-10-16)Several studies have indicated the need for personalizing gamified systems to users' personalities. However, mapping user personality onto design elements is difficult. Hexad is a gamification user types model that attempts ... -
Gaps in the Evidence on Population Interventions to Reduce Consumption of Sugars: A Review of Reviews
(MDPI, 2018-08-08)There is currently considerable attention directed to identifying promising interventions to reduce consumption of sugars among populations around the world. A review of systematic reviews was conducted to identify gaps ... -
Garnet fractionation, progressive melt loss and bulk composition variations in anatectic metabasites: Complications for interpreting the geodynamic significance of TTGs
(Elsevier, 2020-05)Tonalite-trondhjemite-granodiorite (TTG) suites constitute a large proportion of the Archean geological record; however, the geodynamic processes that generated them, and Archean continental crust in general, remain a ... -
The Gaze Cueing Effect and Its Enhancement by Facial Expressions Are Impacted by Task Demands: Direct Comparison of Target Localization and Discrimination Tasks
(Frontiers, 2021-03-11)The gaze cueing effect is characterized by faster attentional orienting to a gazed-at than a non-gazed-at target. This effect is often enhanced when the gazing face bears an emotional expression, though this finding is ... -
Gearbox Fault Detection using Synchro-squeezing Transform
(Elsevier, 2016)This paper presents a novel fault-detection method for gearbox vibration signatures using synchro-squeezing transform (SST). Premised upon the concept of time-frequency (TF) reassignment, SST provides a sharp representation ... -
A gender-stratified, multilevel latent class assessment of chronic disease risk behaviours' association with Body Mass Index among youth in the COMPASS study
(Elsevier, 2019-09)This paper sought to examine chronic disease risk behaviour latent classes and their association with Body Mass Index (BMI), assessing for gender differences. Participants were youth (n = 116,086; grades 9–12) enrolled in ... -
Genesis of a giant Paleoproterozoic strata-bound magnesite deposit: Constraints from Mg isotopes
(Elsevier, 2016-08-01)Giant strata-bound magnesite deposits are absent in modern and most Phanerozoic sedimentary environments but occur predominantly in Precambrian strata. These deposits may have formed directly through precipitation of evolved ... -
Geo-Phisher: The Design and Evaluation of Information Visualizations about Internet Phishing Trends
(IEEE, 2016-06)We designed an information visualization about phishing trends and phishing prevention for the general public to examine the effects of interactivity on information finding, user perceptions and security behaviour intentions, ... -
Geometrical Frustration and Static Correlations in a Simple Glass Former
(American Physical Society, 2012-01-18)We study the geometrical frustration scenario of glass formation for simple hard-sphere models. We find that the dual picture in terms of defects brings little insight and no theoretical simplification for the understanding ... -
Geometrical frustration and static correlations in hard-sphere glass formers
(American Institute of Physics, 2013-03-28)We analytically and numerically characterize the structure of hard-sphere fluids in order to review various geometrical frustration scenarios of the glass transition. We find generalized polytetrahedral order to be correlated ... -
Geophysical response to simulated methane migration in groundwater based on a controlled injection experiment in a sandy unconfined aquifer
(Elsevier, 2019-09)Geophysical methods have the capacity to detect and characterize gas-phase dynamics in groundwater. Suitable methods can be deployed at surface or within boreholes depending on the required depth of investigation, ... -
The Geoweb for community-based organizations: Tool development, implementation, and sustainability in an era of Google Maps
(Community Informatics Journal, 2017-03-22)Recent advances in web-based geospatial tools (the Geoweb) show promise as low-cost and easy-to-use methods to support citizen participation. This research presents two case studies of Geoweb implementation set in ... -
Geriatric Medicine Leadership of Health Care Transformation: To Be or Not To Be?
(Canadian Geriatrics Society, 2013-12-03)Geriatric Medicine is well-suited to inform and lead healthcare system redesign to address the needs of seniors with complex conditions. We posit that geriatricians must urgently consider how to “brand” Geriatric Medicine ... -
Getting Started with Topic Modeling and MALLET
(The Editorial Board of the Programming Historian, 2012-09-02)In this lesson you will first learn what topic modeling is and why you might want to employ it in your research. You will then learn how to install and work with the MALLET natural language processing toolkit to do so. ... -
Gibbs Energy Dynamic Yield Method (GEDYM): Predicting microbial growth yields under energy-limiting conditions
(Elsevier, 2018-11-15)Biomass-explicit biogeochemical models assign microbial growth yields (Y) using values measured in the laboratory or predicted using thermodynamics-based methods. However, Y values are rarely measured under the low energy ... -
Gini-type measures of risk and variability: Gini shortfall, capital allocations, and heavy-tailed risks
(Elsevier, 2017-10-01)We introduce and explore Gini-type measures of risk and variability, and develop the corresponding economic capital allocation rules. The new measures are coherent, additive for co-monotonic risks, convenient computationally, ... -
Glassy States in Asymmetric Mixtures of Soft and Hard Colloids
(APS Physics, 2013-11-14)By employing rheological experiments, mode coupling theory, and computer simulations based on realistic coarse-grained models, we investigate the effects of small, hard colloids on the glassy states formed by large, soft ... -
