Rectus abdominis muscle thickness is a valid measure of cross-sectional area: implications for ultrasound
(Elsevier, 2022-03)Rationale and objectives: The rectus abdominis muscle exhibits early and significant muscle atrophy, which has largely been characterized using ultrasound measured muscle thickness. However, the validity of rectus abdominis ... -
Redistribution of charged aluminum nanoparticles on oil droplets in water in response to applied electrical field
(Springer, 2016-05-18)Janus droplets with two opposite faces of different physical or chemical properties have great potentials in many fields. This paper reports a new method for making Janus droplets by covering one side of the droplet with ... -
Redistribution of mobile surface charges of an oil droplet in water in applied electric field
(Elsevier, 2016-10)Most researches on oil droplets immersed in aqueous solutions assume that the surface charges of oil droplets are, similar to that of solid particles, immobile and distributed uniformly under external electric field. ... -
Redox conditions across the Cambrian–Ordovician boundary: Elemental and isotopic signatures retained in the GSSP carbonates
(Elsevier, 2015-12-15)Lime mudstone samples (rhythmites) were collected at high resolution from outcrops of the Cambrian–Ordovician GSSP boundary section at Green Point (western Newfoundland, Canada). The sequence (~45 mthick) consists of slope ... -
Reducibility of operator semigroups and values of vector states
(Springer, 2017-08-01)Let S be a multiplicative semigroup of bounded linear operators on a complex Hilbert space H, and let Ω be the range of a vector state on S so that Ω = {⟨Sξ, ξ⟩ : S ∈ S} for some fixed unit vector ξ ∈ H. We study the ... -
Reduction of a Vehicle Multibody Dynamic Model Using Homotopy Optimization
(De Gruyter, 2013-03-27)Despite the ever-increasing computational power of modern processors, the reduction of complex multibody dynamic models remains an important topic of investigation, particularly for design optimization, sensitivity analysis, ... -
Reduction of chlorendic acid by zero-valent iron: Kinetics, products, and pathways
(Elsevier, 2020-02-15)Chlorendic acid (CA) is a recalcitrant groundwater contaminant for which an effective treatment technology does not currently exist. In this study, a series of batch experiments were conducted to investigate the treatment ... -
Reduction of Hospital Environmental Contamination Using Automatic UV Room Disinfection
(Global Biorisk Advisory Council, 2021-08-21)The use of mobile ultraviolet (UV) germicidal irradiation has been documented to reduce contamination levels and HAIs in hospitals. However, there is a general lack of information on the efficacy of wall-mounted, automated ... -
Reduction of intersex in a wild fish population in response to major municipal wastewater treatment plant upgrades
(American Chemical Society, 2017)Intersex in fish downstream of municipal wastewater treatment plants (MWWTPs) is a global concern. Consistent high rates of intersex in male rainbow darter (Etheostoma caeruleum) have been reported for several years in the ... -
Reduction of polymer surface tension by crystallized polymer nanoparticles
(AIP Publishing, 2010-10-14)Self-consistent field theory is applied to investigate the effects of crystallized polymer nanoparticles on polymer surface tension. It is predicted that the nanoparticles locate preferentially at the polymer surface and ... -
Reflections on Our Human-Centred Qualitative Data Science Journey
(University of Waterloo, 2022-02-28)We are HCI researchers from the University of Waterloo’s School of Public Health Sciences. Many of our colleagues are social science researchers, and are tackling important issues like vaccine hesitancy, mental health, and ... -
Reflective Peer Mentoring: Evolution of a Professional Development Program for Academic Librarians
(The Editorial Board of Partnership: The Canadian Journal of Library and Information Practice and Research, 2014)For librarians engaged in teaching and learning, reflection has the potential to create opportunities to examine one’s instructional practice, identify and address challenges, and find new instructional pathways. It can ... -
Regenerable DNA-Functionalized Hydrogels for Ultrasensitive, Instrument-Free Mercury(II) Detection and Removal in Water
(American Chemical Society, 2010-09-15)Mercury is a highly toxic environmental pollutant with bioaccumulative properties. Therefore, new materials are required to not only detect but also effectively remove mercury from environmental sources such as water. We ... -
A regenerative NanoOctopus based on multivalent-aptamer functionalized magnetic microparticles for effective cell capture in whole blood
(American Chemical Society, 2019-01-16)Isolation of specific rare cell subtypes from whole blood is critical in cellular analysis and important in basic and clinical research. Traditional immuno-magnetic cell capture suffers from suboptimal sensitivity, ... -
Regional activation of anterior and posterior supraspinatus differs by plane of elevation, hand load and elevation angle
(Elsevier, 2018-12-01)The supraspinatus is one of the muscles of the rotator cuff, and growing research on fibre type composition and mechanical advantages in specific postures suggest this muscle may have distinct anterior and posterior regions. ... -
Regional activation of supraspinatus and infraspinatus sub-regions during dynamic tasks performed with free weights
(Elsevier, 2022-02)Growing evidence supports the existence of distinct anatomical sub-regions within supraspinatus and infraspinatus, but only recently has attention turned to exploring their potential functional differences. Using indwelling ... -
The Regional Extent of Suppression: Strabismics Versus Nonstrabismics
(Association of Research in Vision and Ophthalmology, 2013-10)Purpose.: Evidence is accumulating that suppression may be the cause of amblyopia rather than a secondary consequence of mismatched retinal images. For example, treatment interventions that target suppression may lead to ... -
Regional Time Stepping for SPH
(The Eurographics Association, 2014)This paper presents novel and efficient strategies to spatially adapt the amount of computational effort applied based on the local dynamics of a free surface flow, for classic weakly compressible SPH (WCSPH). Using a ... -
Regression with incomplete covariates and left-truncated time-to-event data
(Wiley, 2013)Studies of chronic diseases routinely sample individuals subject to conditions on an event time of interest. In epidemiology, for example, prevalent cohort studies aiming to evaluate risk factors for survival following ... -
Regression with incomplete multivariate surrogate responses for a latent covariate
(Taylor & Francis, 2020-07-29)We consider the setting in which a categorical exposure variable of interest can only be measured subject to misclassification via surrogate variables. These surrogate variables may represent the classification of an ...
