UCAnDoModels: A Context-based Model Editor for Editing and Debugging UML Class and State-Machine Diagrams
(ACM/IEEE, 2019-09)Practitioners face cognitive challenges when using model editors to edit and debug UML models, which make them reluctant to adopt modelling. To assist practitioners in their modelling tasks, we have developed effective ... -
Ultrahigh Nanoparticle Stability against Salt, pH, and Solvent with Retained Surface Accessibility via Depletion Stabilization
(American Chemical Society, 2012-06-20)For many applications, it is desirable to stabilize colloids over a wide range of buffer conditions while still retaining surface accessibility for adsorption and reaction. Commonly used charge or steric stabilization ... -
An Ultrasensitive Light-up Cu2+ Biosensor Using a New DNAzyme Cleaving a Phosphorothioate-Modified Substrate
(American Chemical Society, 2017-01-15)Cu2+ is a very important metal ion in biology, environmental science, and industry. Developing biosensors for Cu2+ is a key topic in analytical chemistry. DNAzyme-based sensors are highly attractive:, for their excellent ... -
Ultrasonic assisted synthesis, crystallographic, spectroscopic studies and biological activity of three new Zn(II), Co(II) and Ni(II) thiosemicarbazone complexes as precursors for nano-metal oxides
(Elsevier, 2019-01-01)Using ultrasonic irradiations, three new complexes of type [ZnL2].CH3CN, [NiLCl] and [CoL2] (where L is 2-acetylpyridine-4N-p-chlorophenylthiosemicarbazone ligand) have been prepared and investigated using various spectroscopic ... -
Ultrasound image resolution influences analysis of skeletal muscle composition
(Wiley, 2020-06-03)Introduction: Analysis of muscle composition using ultrasound requires standardization of several equipment settings (i.e. gain). However, the influence of image resolution, which is altered by imaging depth, on measures ... -
Ultraviolet-C Irradiation, Heat, and Storage as Potential Methods of Inactivating SARS-CoV-2 and Bacterial Pathogens on Filtering Facepiece Respirators
(Multidisciplinary Digital Publishing Institute, 2022-01-10)The arrival of SARS-CoV-2 to Aotearoa/New Zealand in February 2020 triggered a massive response at multiple levels. Procurement and sustainability of medical supplies to hospitals and clinics during the then upcoming ... -
(Un)Reasonable, (Un)Necessary, and (In)Appropriate Biographic Mediation of Neurodivergence in Academic Accommodations
(Centre for Biographical Research, 2019-12)Biographic mediation of disability through accommodations bureaucracies in the academic workplace attempts to contain and control difference in such a way as to leave intact the fundamentally ableist set of values, practices, ... -
Uncertainty-based multi-criteria calibration of rainfall-runoff models: a comparative study
(Springer, 2014-08-01)This study compares formal Bayesian inference to the informal generalized likelihood uncertainty estimation (GLUE) approach for uncertainty-based calibration of rainfall-runoff models in a multi-criteria context. Bayesian ... -
Unclaimed Prize Information Increases the Appeal of Scratch Card Games
(Taylor and Francis, 2020-11-03)Previous research suggests that intuitively appealing, yet uninformative unclaimed prize information is capable of biasing gambling-related judgments when people compare scratch cards that vary in the number of unclaimed ... -
Uncovering indicators of adaptive water capacity: A rapid systematic map
(University of Waterloo, 2023-05-15)The global water crisis is driven by the absence of effective and efficient governance systems.There is a large and growing need to benchmark the current status of water governance in Canada and monitor trends over time. ... -
Understanding acute stress-mediated immunity in teleost fish
(Elsevier, 2021-12)The abilities and ways in which organisms respond to stress have long been demonstrated to affect the immune response of the organism. In mammalian studies, researchers have observed that chronic/long-term stress has a ... -
Understanding organizational context and heart failure management in long term care homes in Ontario, Canada
(Scientific Research Publishing, 2012-10-01)This study examined the prevalence of Control Intervention (CI) use in adult in-patient psychiatric units/hospitals in Ontario and developed a profile of those patients who had CI use during their admission between April ... -
Understanding Undergraduate Engineering Student Information Access and Needs: Results from a Scoping Review
(American Society for Engineering Education, 2019-06-16)To the authors knowledge this is the first review to examine the current body of research on how engineering students access, use, and understand information; identify gaps in the literature, and how this can be used to ... -
Understanding Youth Transition as 'Becoming': Identity, Time and Futurity
(Elsevier, 2009-11-01)Drawing on recent work in psychology, philosophy, and youth geographies, this article responds to calls for theoretical rigour in children's geographies by developing the concept of becoming for youth transitions research. ... -
Understanding “What Could Be”: A Call for ‘Experimental Behavioral Genetics’
(Springer, 2018-08-13)Behavioral genetic (BG) research has yielded many important discoveries about the origins of human behavior, but offers little insight into how we might improve outcomes. We posit that this gap in our knowledge base stems ... -
Uneven temperature and voltage distributions due to rapid discharge rates and different boundary conditions for series-connected LiFePO4 batteries
(Elsevier, 2017-02-01)This paper presents the surface temperature and voltage distributions on a prismatic lithium-ion battery pack at 1C, 2C, 3C, and 4C discharge rates and 5°C, 15°C, 25°C, and 35°C boundary conditions (BCs) for water cooling ... -
A Unified Simplicial Model for Mixed-Dimensional and Non-Manifold Deformable Elastic Objects
