Protocol for Usability Testing and Validation of the ISO Draft International Standard 19223 for Lung Ventilators
(JMIR, 2017-09)Background: Clinicians, such as respiratory therapists and physicians, are often required to set up pieces of medical equipment that use inconsistent terminology. Current lung ventilator terminology that is used by different ... -

Provocations from #vanlife: Investigating Life and Work in a Community Extensively Using Technology Not Designed for Them
(ACM, 2021-05)Research on how lived experiences with technology intersect with home and work are core themes within HCI. Prior work has primarily focused on conventional life and work in Western countries. However, the unconventional ... -
Psychological Prices at Retail Gasoline Stations: The Policies of 0-, 5-, and 9-Ending Prices
(Taylor & Francis, 2021-07-12)Psychological prices are known to impact consumer behaviour and to depend on retailers’ characteristics. Less understood is last digit pricing, especially in the context of retail gasoline stations. We study price endings ... -
PtSe2 Field-Effect Transistors: New Opportunities for Electronic Devices
(Institute of Electrical and Electronics Engineers, 2017-11-15)PtSe2, a new family of transition metal dichalcogenides, has been explored for electronic device applications using density functional theory (DFT) and non-equilibrium Green’s function (NEGF) within the third nearest ... -
Pure Pairs VI. Excluding an Ordered Tree.
(Society for Industrial and Applied Mathematics Journal on Discrete Mathematics, 2022-01)A pure pair in a graph G is a pair (Z1,Z2) of disjoint sets of vertices such that either every vertex in Z1 is adjacent to every vertex in Z2, or there are no edges between Z1 and Z2. With Maria Chudnovsky, we recently ... -
Pure pairs. I. Trees and linear anticomplete pairs
(Elsevier, 2020-12-02)The Erdős-Hajnal conjecture asserts that for every graph H there is a constant c > 0 such that every graph G that does not contain H as an induced subgraph has a clique or stable set of cardinality at least |G|c. In this ... -
Pure pairs. II. Excluding all subdivisions of a graph
(Springer Nature, 2021-06-01)We prove for every graph H there exists ɛ > 0 such that, for every graph G with |G|≥2, if no induced subgraph of G is a subdivision of H, then either some vertex of G has at least ɛ|G| neighbours, or there are two disjoint ... -
Pure pairs. III. Sparse graphs with no polynomial-sized anticomplete pairs
(Wiley, 2020-11)A graph is H-free if it has no induced subgraph isomorphic to H, and |G| denotes the number of vertices of G. A conjecture of Conlon, Sudakov and the second author asserts that: - For every graph H, there exists ∈ > 0 ... -
Pyrene Excimer Fluorescence as a Direct and Easy Experimental Means to Characterize the Length Scale and Dynamics of Polypeptide
(American Chemical Society, 2018-04-26)This report provides evidence that the blobs characterized through the application of the fluorescence blob model (FBM) to the analysis of the fluorescence decays acquired with pyrene-labeled polypeptides are equivalent ... -
Pyrenyl Derivative with a Four-Atom Linker That Can Probe the Local Polarity of Pyrene-Labeled Macromolecules
(American Chemical Society, 2016-02-04)The fluorescent probe 1-pyrenemethoxyethanol (PyMeEGOH) was designed to replace commercially available 1-pyrenebutanol (PyButOH) as an alternative fluorescent label to probe the internal dynamics and interior polarity of ... -
Pyrolysis, kinetics analysis, thermodynamics parameters and reaction mechanism of Typha latifolia to evaluate its bioenergy potential
(Elsevier, 2017-09-01)This work was focused on understanding the pyrolysis of Typha latifolia. Kinetics, thermodynamics parameters and pyrolysis reaction mechanism were studied using thermogravimetric data. Based on activation energies and ... -
Quality of Dementia Care in the Community: Identifying Key Quality Assurance Components
(Canadian Geriatrics Society, 2016-12-01)Background: Primary care-based memory clinics (PCMCs) have been established in several jurisdictions to improve the care for persons with Alzheimer’s disease and related dementias. We sought to identify key quality indicators ... -
Quantification of MUCIN 1, cell surface associated and MUCIN16, cell surface associated proteins in tears and conjunctival epithelial cells collected from postmenopausal women
(Molecular Vision, 2013-05-04)Purpose: To quantify the expression of mucin 1, cell surface associated (MUC1) and mucin 16, cell surface associated (MUC16) proteins and messenger ribonucleic acid (mRNA) in a cohort of postmenopausal women (PMW), to ... -
Quantifying entanglement of rotor chains using basis truncation: Application to dipolar endofullerene peapods
(American Institute of Physics, 2018-02-21)We propose a variational approach for the calculation of the quantum entanglement entropy of assemblies of rotating dipolar molecules. A basis truncation scheme based on the total angular momentum quantum number is proposed. ... -
