Vaccines for finfish aquaculture: What do we need to know to make them work?
(Elsevier, 2012-08-08)Aquaculture still faces serious economic impacts due to the loss of animals to disease. A conservative estimate of 5% losses due to disease means that the finfish aquaculture industry loses over $1 billion annually on a ... -
Validity and Reliability of a Short Diet Questionnaire to Estimate Dietary Intake in Older Adults in a Subsample of the Canadian Longitudinal Study on Aging
(MDPI, 2018-10-17)This study assessed test-retest reliability and relative validity of the Short Diet Questionnaire (SDQ) and usability of an online 24 h recall among 232 participants (62 years ± 9.1; 49.6% female) from the Canadian ... -
Value from adversity: How we deal with adversity matters
(Elsevier, 2012-07-01)Participants in our study worked on an anagram task to win a prize while aversive noise played in the background. They were instructed to deal with the noise either by “opposing” it as an interference or by “coping” with ... -
The Value of Admission Clinical Data for Diagnosing Heart Failure in Long-term Care
(Canadian Geriatrics Society, 2013-12-03)Background Heart failure (HF) is common in long-term care (LTC). Diagnostic uncertainty is important barrier to optimal HF management, stemming from inadequate health information transfer upon LTC admission. We determine ... -
The value of multiple perspectives: Problem-solving and critique in the evaluation of social acceptance research—A response to M. Wolsink
(Elsevier, 2019-02-01)Established social acceptance scholar Maarten Wolsink recently published in these pages a critique of an earlier paper of ours, also published in ERSS. In this response, we will review some of Wolsink’s specific methodological ... -
Variable pay: Is it for the worker or the firm?
(Elsevier, 2019-10)Why do firms pay their workers with variable pay? The standard explanation appeals to a problem that the worker faces, e.g., agency. We develop a model of variable pay endogenously driven by the capital structure problem ... -
Variable selection and prediction in biased samples with censored outcomes
(Springer, 2018-01-01)With the increasing availability of large prospective disease registries, scientists studying the course of chronic conditions often have access to multiple data sources, with each source generated based on its own entry ... -
Variational Stokes: A Unified Pressure-viscosity Solver for Accurate Viscous Liquids
(Association for Computing Machinery, 2017-07-20)We propose a novel unsteady Stokes solver for coupled viscous and pressure forces in grid-based liquid animation which yields greater accuracy and visual realism than previously achieved. Modern fluid simulators treat ... -
VER-155008 induced Hsp70 proteins expression in fish cell cultures while impeding replication of two RNA viruses
(Elsevier, 2019-02-01)The heat-shock protein 70 (Hsp70) inhibitor, VER-155008 (VER), was explored as a potential antiviral agent for two RNA viruses important to fish aquaculture, viral hemorrhagic septicemia virus (VHSV) and infectious pancreatic ... -
Vernacular Knowledge and Water Management - Towards the Integration of Expert Science and Local Knowledge in Ontario, Canada
(Water Alternatives Association, 2015-10)Complex environmental problems cannot be solved using expert science alone. Rather, these kinds of problems benefit from problem-solving processes that draw on ‘vernacular’ knowledge. Vernacular knowledge integrates expert ... -
Versatile and efficient pore network extraction method using marker-based watershed segmentation
(American Physical Society, 2017-08-16)Obtaining structural information from tomographic images of porous materials is a critical component of porous media research. Extracting pore networks is particularly valuable since it enables pore network modeling ... -
A Vertex-Weighted Tutte Symmetric Function, and Constructing Graphs with Equal Chromatic Symmetric Function
(The Electronic Journal of Combinatorics, 2021-04-09)This paper has two main parts. First, we consider the Tutte symmetric function XB, a generalization of the chromatic symmetric function. We introduce a vertex-weighted version ofXB, show that this function admits a ... -
Vertically rooting multifunctional tentacles on carbon scaffold as efficient polysulfide barrier toward superior lithium-sulfur batteries
(Elsevier, 2019-10)The rational design of sulfur barrier/host materials plays essential roles in developing high-performance lithium-sulfur (Li-S) batteries. Herein, we developed a hierarchically fibrous framework to establish a conductive, ... -
Veterans and military masculinity in popular romance fiction
(Taylor & Francis, 2018)Although popular culture has become an important area of study in international relations, few scholars so far have turned their attention to popular romance fiction, despite its popularity among readers. Through an analysis ... -
A video-driven model of response statistics in the primate middle temporal area
(Elsevier, 2018-12-01)Neurons in the primate middle temporal area (MT) encode information about visual motion and binocular disparity. MT has been studied intensively for decades, so there is a great deal of information in the literature about ... -
Virtual Reality Applications in Rehabilitation
(Springer, 2016-06-19)One of the most valuable applications of virtual reality (VR) is in the domain of rehabilitation. After brain injuries or diseases, many patients suffer from impaired physical and/or cognitive capabilities, such as ... -
Visual attention to threat during stove-checking in people high in checking behaviour
(Elsevier ScienceDirect, 2022-10)Leading models of obsessive-compulsive disorder (OCD) state that hypervigilance to threat is a factor in compulsion persistence; however, previous research on attention deployment in OCD is mixed. The current study examines ... -
Visual detection of lead(II) using a label-free DNA-based sensor and its immobilization within a monolithic hydrogel
(Royal Society of Chemistry, 2012-02-07)Lead is highly toxic and its detection has attracted a lot of research interests. In recent years, DNA has been used for Pb2+ recognition and many fluorescent sensors with low to sub-nM detection limits have been reported. ... -
Visual Impairment in the City: Young People's Social Strategies for Independent Mobility
(Sage, 2013-02-01)This article examines the mobility strategies that visually impaired (VI) young people employ as they negotiate their daily lives in the city. In contrast to research which foregrounds difficulties navigating the built ... -
Visual optical biosensors based on DNA-functionalized polyacrylamide hydrogels
(Elsevier, 2013-12-15)Biosensors are devices that can provide quantitative or semi-quantitative analytical information about target molecules, where molecular recognition is based on biomolecular interactions. In recent years, DNA has emerged ...
