The effects of flagellar hook compliance on motility of monotrichous bacteria: A modeling study
(AIP Publishing, 2012-06)A crucial structure in the motility of flagellated bacteria is the hook, which connects the flagellum filament to the motor in the cell body. Early mathematical models of swimming bacteria assume that the helically shaped ... -
Effects of graphene nano-platelets (GNPs) on the microstructural characteristics and textural development of an Al-Mg alloy during friction-stir processing
(Elsevier, 2018-02-15)The aim of this research is to characterize the unique microstructural features of Al-matrix nanocomposites reinforced by graphene nano-platelets (GNPs), fabricated by multi-pass friction-stir processing (FSP). During this ... -
The Effects of Home Exercise in Older Women With Vertebral Fractures: A Pilot Randomized Controlled Trial
(Oxford, 2020-04)Background Regular exercise is advocated in osteoporosis guidelines to prevent fractures. Few studies have evaluated the effect of exercise on functional performance, posture, and other outcomes that are important to ... -
The effects of imagery rescripting on memory outcomes in social anxiety disorder
(Elsevier, 2020-01)Imagery rescripting (IR) is an effective intervention for social anxiety disorder (SAD) that targets negative autobiographical memories. IR has been theorized to work through various memory mechanisms, including modifying ... -
Effects of ionic concentration gradient on electroosmotic flow mixing in a microchannel
(Elsevier, 2014-11-08)Effects of ionic concentration gradient on electroosmotic flow (EOF) mixing of one stream of a high concentration electrolyte solution with a stream of a low concentration electrolyte solution in a microchannel are ... -
Effects of Mask-Wearing on Social Anxiety: An Exploratory Review
(Taylor & Francis, 2021-06-01)Background A unique feature of the global coronavirus pandemic has been the widespread adoption of mask-wearing as a public health measure to minimize the risk of contagion. Little is known about the effects of increased ... -
Effects of molecular crowding and confinement on the spatial organization of a biopolymer
(Royal Society of Chemistry, 2016-10-25)A chain molecule can be entropically collapsed in a crowded medium in a free or confined space. Here, we present a unified view of how molecular crowding collapses a flexible polymer in three distinct spaces: free, ... -
Effects of peripheral eccentricity and head orientation on gaze discrimination
(Taylor & Francis, 2014-11-26)Visual search tasks support a special role for direct gaze in human cognition, while classic gaze judgement tasks suggest the congruency between head orientation and gaze direction plays a central role in gaze perception. ... -
The Effects of Personal Religiosity and Spirituality on Informal Caregiving Activities
(2018-09-07)With data from the 2012 Canadian General Social Survey on Caregiving and Care Receiving, this study measures how religion and spirituality impact a respondent’s informal caregiving activities. Building on existing psychology ... -
Effects of Polyethylene Glycol on DNA Adsorption and Hybridization on Gold Nanoparticles and Graphene Oxide
(American Chemical Society, 2012-10-09)Understanding the interface between DNA and nanomaterials is crucial for rational design and optimization of biosensors and drug delivery systems. For detection and delivery into cells, where high concentrations of cellular ... -
The effects of positive interpretation bias on cognitive reappraisal and social performance: Implications for social anxiety disorder
(Elsevier, 2020-08)People with social anxiety disorder (SAD) lack non-socially anxious individuals' tendency to interpret ambiguous social information in a positively biased manner. To gain a better understanding of the specific in-vivo ... -
Effects of post-processing on the thermomechanical fatigue properties of laser modified NiTi
(Elsevier, 2019-01-01)The multifunctional capabilities needed for advanced shape memory alloys (SMA) actuators has been shown to be achievable by locally tuning the properties through laser processing. Before the wide-spread use of these SMAs ... -
Effects of task demands on the early neural processing of fearful and happy facial expressions
(Elsevier, 2017-05-15)Task demands shape how we process environmental stimuli but their impact on the early neural processing of facial expressions remains unclear. In a within-subject design, ERPs were recorded to the same fearful, happy and ... -
The Effects of tDCS Across the Spatial Frequencies and Orientations that Comprise the Contrast Sensitivity Function
(Frontiers Media, 2015-11-27)Transcranial Direct Current Stimulation (tDCS) has recently been employed in traditional psychophysical paradigms in an effort to measure direct manipulations on spatial frequency channel operations in the early visual ... -
The Effects of Winter Pulsed Warming and Snowmelt on Nitrogen Cycling in Agricultural Soils: A Lysimeter Study
(University of Waterloo, 2023-05-15)In cold regions, climate change is expected to result in warmer winter temperatures and increased temperature variability. Coupled with changing precipitation regimes, these changes can decrease soil insulation by reducing ... -
Efficient electrochemical model for lithium-ion cells
(2017-09-12)Lithium-ion batteries are used to store energy in electric vehicles. Physical models based on electro-chemistry accurately predict the cell dynamics, in particular the state of charge. However, these models are nonlinear ... -
Efficient fast Fourier transform-based numerical implementation to simulate large strain behavior of polycrystalline materials
(Elsevier, 2017-07-04)In this paper, a new full-field numerical framework is proposed to model large strain phenomena in polycrystals. The proposed framework is based on the elasto-viscoplastic (EVP) fast Fourier transform (FFT) formulation ... -
