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 ... -
An Efficient Geometric Multigrid Solver for Viscous Liquids
(ACM, 2019-07)We present an efficient geometric Multigrid solver for simulating viscous liquids based on the variational approach of Batty and Bridson [2008]. Although the governing equations for viscosity are elliptic, the strong ... -
An Efficient Lanthanide-Dependent DNAzyme Cleaving 2 '-5 '-Linked RNA
(Wiley, 2016-05-17)RNA can form two types of linkage. In addition to the predominant 3'-5' linkage, 2'-5'-linked RNA is also important in biology, medicine, and prebiotic studies. Here, in vitro selection was used to isolate a DNAzyme that ... -
Efficient polyyne formation by ns and fs laser-induced breakdown in ethylene and acetylene gas flow
(Elsevier, 2019-11)We studied polyyne formation by gas phase laser-induced breakdown in ethylene and acetylene gas flow using ns and fs lasers. The results show that acetylene is the most efficient target molecule for generating polyynes ... -
Efficient Simulation Of Complex Fenestration Systems In Heat Balance Room Models
(International Building Performance Simulation Association, 2011-11)The solar, longwave, and convective interactions between a window, its shading attachments and its surroundings constitute a complicated coupled heat balance problem that can entail significant computational intensity to ... -
Efficient treatment of climate data uncertainty in ensemble Kalman filter (EnKF) based on an existing historical climate ensemble dataset
(Elsevier, 2019-01)Successful data assimilation depends on the accurate estimation of forcing data uncertainty. Forcing data uncertainty is typically estimated based on statistical error models. In practice, the hyper-parameters of statistical ... -
