Role of loading direction on cyclic behaviour characteristics of AM30 extrusion and its fatigue damage modelling
(Elsevier, 2017-07-18)Anisotropic fatigue and cyclic behaviour of AM30 Mg alloy extrusion is investigated by performing fully-reversed strain-controlled tension-compression cyclic tests at strain amplitudes between 0.3% and 2.3%, along extrusion ... -
The role of metamotivation in creating task-motivation fit
(American Psychological Association, 2016)One of the challenges of effective goal pursuit is being able to flexibly adapt to changing situations and demands. The current studies investigate whether individuals exhibit effective metamotivation—successful management ... -
The Role of pH, Ionic Strength and Monomer Concentration on the Terpolymerization of 2-Acrylamido-2-methylpropane Sulfonic Acid, Acrylamide and Acrylic Acid
(Elsevier, 2019-08-26)The current study examines the effects of important factors (namely, pH, ionic strength and monomer concentration) on the terpolymerization of 2-acrylamido-2-methylpropane sulfonic acid (AMPS), acrylamide (AAm) and acrylic ... -
The role of science in sustainability transitions: Citizen science, transformative research, and experiences from Samothraki island, Greece
(University of Prince Edward Island, 2017-05-01)We highlight the importance of island research that aims to achieve sustainability transitions. All too often, developmental priorities are largely defined by economic policy imperatives, and island research either ignores ... -
The role of somatosensory input in target localization during binocular and monocular viewing while performing a high precision reaching and placement task
(Elsevier, 2019-06)Binocular vision provides the most accurate and precise depth information; however, many people have impairments in binocular visual function. It is possible that other sensory inputs could be used to obtain reliable depth ... -
The Role of Wastewater Testing for SARS-CoV-2 Surveillance
(Ontario COVID-19 Science Advisory Table, 2021-08-26)Wastewater testing for SARS-CoV-2 is relatively new; however, it builds on existing public health surveillance infrastructure. There is a limited but growing evidence base for its use, despite notable interpretation ... -
Role Of Word-Of-Mouth For Programs Of Voluntary Vaccination: A Game-Theoretic Approach
(Elsevier, 2015-11-01)We propose a model describing the synergetic feedback between word-of-mouth (WoM) and epidemic dynamics controlled by voluntary vaccination. The key feature consists in combining a game-theoretic model for the spread of ... -
Rome, the Seleukid East and the Disintegration of the Largest of the Successor Kingdoms in the 2nd Century BC
(Société Latomus, Brussels, 2019-05-18)Although Antiochos III Megas had been defeated by the Romans in 191/90 BC, his son Seleukos IV managed to consolidate it, and his youngest son Antiochos IV Epiphanes (175– 164) even became the most powerful monarch of ... -
Roth's theorem on systems of linear forms in function fields
(Institute of Mathematics, 2010)1. Introduction. For r, s ∈ N = {1, 2, . . .} with s ≥ 2r + 1, let (bi,j ) be an r×s matrix whose elements are integers. Suppose that bi,1+· · ·+bi,s = 0 (1 ≤ i ≤ r). Suppose further that among the columns of the matrix, ... -
Saccade latency delays in young apolipoprotein E (APOE) epsilon 4 carriers
(Elsevier, 2018-11-01)The apolipoprotein E (APOE) epsilon 4 isoform has been associated with a significantly greater risk of developing late onset Alzheimer’s disease (AD). However, the negative effects of APOE-ε4 allele on cognitive function ... -
Sagging resistance of warm formed aluminum brazing sheet
(Elsevier, 2018-04-01)Interrupted tensile tests, performed between room temperature (RT) and 250°C, were used to simulate warm forming of an AA3003/AA4045 brazing sheet. Brazing performance was predicted from sagging distance measurements after ... -
Salinization enhances eutrophication symptoms in a cold temperate urban lake
(Elsevier, 2022-11-10)Salinization of inland freshwaters is observed around the world, but particularly in cold temperate regions due to the runoff of salt applied on roads as de-icing agents during the winter. This is the case for Lake Wilcox, ... -
Salinization increases eutrophication symptoms in freshwater urban lakes of North America
(University of Waterloo, 2023-05)The acceleration of global urbanization continues to fuel concerns surrounding water quality impairments in urban lakes, particularly their eutrophication. Eutrophication of freshwater environments is generally assumed to ... -
The Saliva Exposome for Monitoring of Individuals’ Health Trajectories
(Environmental Health Perspectives - United States Federal Government, 2017-07-20)Background: There is increasing evidence that environmental, rather than genetic, factors are the major causes of most chronic diseases. By measuring entire classes of chemicals in archived biospecimens, exposome-wide ... -
Sample size and robust marginal methods for cluster-randomized trials with censored event times
(Wiley, 2015-03-15)In cluster-randomized trials, intervention effects are often formulated by specifying marginal models, fitting them under a working independence assumption, and using robust variance estimates to address the association ... -
Sandwich and probe problems for excluding paths
(Elsevier, 2018-12-31)Let Pk denote an induced path on k vertices. For k ≥ 5, we show that the Pk-free sandwich problem, partitioned probe problem, and unpartitioned probe problem are NP-complete. For k ≤ 4, it is known that the Pk-free sandwich ... -
The Sandwich Problem for Decompositions and Almost Monotone Properties
(Springer Nature, 2018)We consider the graph sandwich problem and introduce almost monotone properties, for which the sandwich problem can be reduced to the recognition problem. We show that the property of containing a graph in C as an induced ... -
Scalable image segmentation via decoupled sub-graph compression
(Elsevier, 2018-06-01)Dealing with large images is an on-going challenge in image segmentation, where many of the current methods run into computational and/or memory complexity issues. This work presents a novel decoupled sub-graph compression ... -
Scale-dependent anisotropy in forced stratified turbulence
(American Physical Society, 2019-04)In stratified turbulence, buoyancy forces inhibit vertical motion and lead to anisotropy over a wide range of length scales, which is characterized by layerwise pancake vortices, thin regions of strong shear, and patches ... -
Scared of compassion: Fear of compassion in anxiety, mood, and non-clinical groups
(British Psychological Society, 2020-05-04)Objectives. Fear of receiving compassion from others, expressing compassion to others, and being compassionate towards oneself have been identified as potentially important factors in the persistence of depression, stress ...
