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 ... -
Visualising data distributions with kernel density estimation and reduced chi-squared statistic
(Elsevier, 2017-11-01)The application of frequency distribution statistics to data provides objective means to assess the nature of the data distribution and viability of numerical models that are used to visualize and interpret data. Two ... -
Visualization of bivariate sequence length-chain length distribution in free radical copolymerization
(Wiley, 2017-08)Copolymer properties and processability depend on copolymer microstructure, i.e., copolymer composition and monomer unit arrangements along copolymer chains. To predict ultimate properties of copolymers, one needs complete ... -
Visualizing social acceptance research: A bibliometric review of the social acceptance literature for energy technology and fuels
(Elsevier, 2018-06-01)This paper conducts content and bibliometric analysis of 857 articles representing the knowledge domain for the social acceptance of energy technology and fuels. The objective is to identify basic trends and characteristics ... -
“Vital acts of transfer”: Affective economies and embodied knowledge in #MeToo
(Intellect, 2021-01-22)This book chapter situates the #MeToo movement as a live, ongoing performance within the digital media sphere. It argues that performance theory offers a unique means of grasping at the movement’s significance and on-going ... -
Vital Energy Regulator: A Time-Independent Solution for Control of Lower Limb Exoskeletons
(IEEE, 2021-10)In this letter, we introduce a novel control strategy called Virtual Energy Regulator (VER) for lower limb rehabilitation exoskeletons. Unlike the conventional trajectory tracking controllers, VER, which is a time-independent ... -
Vitamin D supplements: Magic pill or overkill?
(Bangladesh Journals Online, 2016-07-25)Vitamin D is a multifunctional micronutrient that exerts hormonal effects on many organs of the body. 1,25 dihydroxyvitamin D is the active metabolite of vitamin D, formed by dual hydroxylation in the liver and kidney. -
Voicing Dissonance: Resistant Soundscapes in 1960s Feminist Experimental Film
(University of California Press, 2015-10-01)This article examines how sound was used as an effective tool of formal resistance in the work of influential feminist filmmakers, Carolee Schneemann (United States), Gunvor Nelson (Sweden), and Joyce Wieland (Canada). ... -
Volunteered Drone Imagery: Challenges and constraints to the development of an open shared image repository
(2017-01-04)Orthorectified imagery is valuable for a wide range of initiatives including environmental change detection, planning, and disaster response. Obtaining aerial imagery at high temporal and spatial scale has traditionally ... -
Vortex break-down during the impact of a starting subsonic compressible gas jet on a multi-plume spray
(Springer, 2016-11-01)The impact process and the consequent two-phase interaction for a compressible subsonic starting gas jet colliding on a multi-plume spray are investigated using large eddy simulation with Eulerian/Lagrangian multiphase ... -
Vortices around Janus droplets under externally applied electrical field
(Springer, 2016-05)In this study, the Janus droplet is an oil droplet covered with aluminum oxide nanoparticles on one side of the droplet surface under applied DC electrical field. The vortices around Janus droplets fixed on a horizontal ... -
“Wait and see” vaccinating behavior during a pandemic: a game theoretic analysis
(Elsevier, 2011-07-26)During the 2009 H1N1 pandemic, many individuals adopted a “wait and see” approach to vaccinating until further information was available on the course of the pandemic and emerging vaccine risks. This behaviour implies two ... -
Waiting Time Distributions in the Preemptive Accumulating Priority Queue
(Springer, 2017-03-01)We consider a queueing system in which a single server attends to N priority classes of customers. Upon arrival to the system, a customer begins to accumulate priority linearly at a rate which is distinct to the class to ... -
Walking the Talk: Editing Wikipedia with Purpose
(2020-03-10)Started nineteen years ago Wikipedia is one of the most visited websites on the Internet, but its popularity is not without issue. Editors are predominantly males from the global north which has led to documented systemic ... -
Wall turbulence response to surface cooling and formation of strongly stable stratified boundary layers
(AIP, 2019-08-20)This paper investigates the processes by which stable boundary layers are formed through strong surface cooling imposed on neutrally stratified wall-bounded turbulence using high-resolution direct numerical simulation at ... -
Waring's problem in function fields
(De Gruyter, 2010)Let Fq½t denote the ring of polynomials over the finite field Fq of characteristic p, and write Jk q ½t for the additive closure of the set of kth powers of polynomials in Fq½t. Define GqðkÞ to be the least integer s ... -
