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 ... -
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
(ACM, 2019-07)We present a unified method to simulate deformable elastic bodies consisting of mixed-dimensional components represented with potentially non-manifold simplicial meshes. Building on well-known simplicial rod, shell, and ... -
Universal bounds for positive matrix semigroups
(Polish Academy of Sciences, 2016)We show that any compact semigroup of positive n×n matrices is similar (via a positive diagonal similarity) to a semigroup bounded by n√. We give examples to show this bound is best possible. We also consider the effect ... -
Universal formula for the holographic speed of sound
(Elsevier, 2018-06-10)We consider planar hairy black holes in five dimensions with a real scalar field in the Breitenlohner–Freedman window and derive a universal formula for the holographic speed of sound for any mixed boundary conditions of ... -
Unmasking the linear behaviour of slow motor adaptation to prolonged convergence
(Wiley, 2016-06)Adaptation to changing environmental demands is central to maintaining optimal motor system function. Current theories suggest that adaptation in both the skeletal-motor and oculomotor systems involves a combination of ... -
