2-Aminopurine-modified DNA homopolymers for robust and sensitive detection of mercury and silver
(Elsevier, 2017-01-15)Heavy metal detection is a key topic in analytical chemistry. DNA-based metal recognition has advanced significantly producing many specific metal ligands, such as thymine for Hg2+ and cytosine for Ag+. For practical ... -
A 2-class maintenance model with dynamic server behavior
(Springer, 2019-04-29)We analyze a 2-class maintenance system within a single-server polling model framework. There are C+f machines in the system, where C is the cap on the number of machines that can be turned on simultaneously (and hence, ... -
A 30-Year Study of Impacts, Recovery, and Development of Critical Effect Sizes for Endocrine Disruption in White Sucker (Catostomus commersonii) Exposed to Bleached-Kraft Pulp Mill Effluent at Jackfish Bay, Ontario, Canada
(Frontiers, 2021-04-22)Jackfish Bay is an isolated bay on the north shore of Lake Superior, Canada that has received effluent from a large bleached-kraft pulp mill since the 1940s. Studies conducted in the late 1980s found evidence of reductions ... -
3D bioprinting of liver-mimetic construct with alginate/cellulose nanocrystal hybrid bioink
(Elsevier, 2018-03-01)3D bioprinting is a novel platform for engineering complex, three-dimensional (3D) tissues that mimic real ones. The development of hybrid bioinks is a viable strategy that integrates the desirable properties of the ... -
A 3D ellipsoidal volumetric foot–ground contact model for forward dynamics
(Springer, 2018-04-01)Foot–ground contact models are an important part of forward dynamic biomechanic models, particularly those used to model gait, and have many challenges associated with them. Contact models can dramatically increase the ... -
3D N-doped hybrid architectures assembled from 0D T-Nb2O5 embedded in carbon microtubes toward high-rate Li-ion capacitors
(Elsevier, 2019-02)Herein, a unique nitrogen-doped T-Nb2O5/tubular carbon hybrid structure in which T-Nb2O5 nanoparticles are homogeneously embedded in an in-situ formed nitrogen-doped microtubular carbon is synthesized, utilizing a facile ... -
3D representation and CNC machining of 2D digital images
(Elsevier, 2018-01-01)In this paper a new paradigm for CNC carving of digital images in the form of lookalike three-dimensional (3D) surfaces on wooden or metallic plaques is discussed. This work is focused on development of a single page windows ... -
ABCD and beyond: From grain merchants to agricultural value chain managers
(Canadian Food Studies, 2015-09-08)The world of agricultural commodity trading firms has changed over the years, although corporate concentration has long been a defining feature of this sector. The four dominant agricultural trading firms—the ABCDs (ADM, ... -
Abelian, amenable operator algebras are similar to C∗ -algebras
(Duke University Press, 2016-12)Suppose that H is a complex Hilbert space and that ℬ(H) denotes the bounded linear operators on H. We show that every abelian, amenable operator algebra is similar to a C∗-algebra. We do this by showing that if 𝒜⊆ℬ(H) is ... -
Accelerating peroxidase mimicking nanozymes using DNA
(Royal Society of Chemistry, 2015-09-07)DNA-capped iron oxide nanoparticles are nearly 10-fold more active as a peroxidase mimic for TMB oxidation than naked nanoparticles. To understand the mechanism, the effect of DNA length and sequence is systematically ... -
Acceptance of Commercially Available Wearable Activity Trackers Among Adults Aged Over 50 and With Chronic Illness: A Mixed-Methods Evaluation
(JMIR Mhealth Uhealth., 2016-01-27)Background: Physical inactivity and sedentary behavior increase the risk of chronic illness and death. The newest generation of “wearable” activity trackers offers potential as a multifaceted intervention to help people ... -
Access roads impact enzyme activities in boreal forested peatlands
(Elsevier, 2019-02-15)We investigated the impacts of resource access roads on soil enzyme activities in contrasting forested boreal peatlands (bog and fen). In August 2016, a total of 72 peat samples were collected from twelve 20 m long transects ... -
Accumulative fold-forging (AFF) as a novel severe plastic deformation process to fabricate a high strength ultra-fine grained layered aluminum alloy structure
(Elsevier, 2018-02-01)A novel severe plastic deformation (SPD) process termed accumulative fold forging (AFF) is introduced to fabricate a homogenous ultra-fine grained (UFG) layered metal structure by repetitive folding and forging aluminum ... -
Accuracy of Parental Reporting of Preschoolers’ Dietary Intake Using an Online Self-Administered 24-h Recall
(MDPI, 2018-07-29)Parents are typically relied upon to report young children’s dietary intake. However, there has been limited research assessing the accuracy of such reports captured using novel dietary assessment tools. The purpose of the ... -
Accuracy of self-reported intake of signature foods in a school meal intervention study: comparison between control and intervention period
(Cambridge University Press, 2015-08-28)Bias in self-reported dietary intake is important when evaluating the effect of dietary interventions, particularly for intervention foods. However, few have investigated this in children, and none have investigated the ... -
Accurate determination of interface trap state parameters by admittance spectroscopy in the presence of a Schottky barrier contact: Application to ZnO-based solar cells
(AIP Publishing, 2013-04-14)This work shows that when a Schottky barrier is present in a photovoltaic device, such as in a device with an ITO/ZnO contact, equivalent circuit analysis must be performed with admittance spectroscopy to accurately determine ... -
