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 Mixed Mode Loading and Bond Line Thickness on Adhesive Joint Strength Using Novel Test Specimen Geometry
(Elsevier, 2020-10)This study quantifies the effect of mixed mode loading and bond line thickness on adhesive joint strength or automotive structural applications. This research is motivated by the need to address the complex loading that ... -
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. ... -
Quantifying the Level of Intermacromolecular Interactions in Ethylene-Propylene Copolymers by Using Pyrene Excimer Formation
(American Chemical Society, 2015-07-14)A unique methodology based on fluorescence measurements is introduced to quantitatively measure the actual level of interpolymeric association between ethylene-propylene (EP) copolymers used as viscosity index improvers ... -
Quantifying trailing edge flap control capability on wind turbines in a controlled environment
(American Institute of Aeronautics and Astronautics (AIAA), 2021-08)As wind turbine diameters continue to increase, the cyclic loading experienced by the turbine blade due to wind shear and yaw misalignment increases dramatically hindering the development of larger more efficient turbines. ... -
Quantitative analysis of biofluid spots by coated blade spray mass spectrometry, a new approach to rapid screening
(Springer Nature, 2017-11-23)This study demonstrates the quantitative capabilities of coated blade spray (CBS) mass spectrometry (MS) for the concomitant analysis of multiple target substances in biofluid spots. In CBS-MS the analytes present in a ... -
Quantitative Characterization of the Molecular Dimensions of Flexible Dendritic Macromolecules by Pyrene Excimer Fluorescence
(American Chemical Society, 2018-02-12)Eight pyrene labeled dendrons (PyLDs) were prepared with a polyester backbone of bis(hydroxymethyl)propionic acid and the monomer and excimer fluorescence decays of the PyLDs were acquired and fitted according to the ... -
Quantum correlations in a noisy neutron interferometer
(American Physical Society, 2014-09-15)We investigate quantum coherences in the presence of noise by entangling the spin and path degrees of freedom of the output neutron beam from a noisy three-blade perfect crystal neutron interferometer. We find that in the ... -
Quantum reference frames associated with non-compact groups: the case of translations and boosts, and the role of mass
(American Physical Society, 2016-03)Quantum communication without a shared reference frame or the construction of a relational quantum theory requires the notion of a quantum reference frame. We analyze aspects of quantum reference frames associated with ... -
Quantum-information approach to dynamical diffraction theory
(American Physical Society, 2016-12-08)We present a simplified model for dynamical diffraction of particles through a periodic thick perfect crystal based on repeated application of a coherent beam-splitting unitary at coarse-grained lattice sites. By demanding ... -
A quasi-experimental examination of how changes in school-level intramurals are associated with physical activity among a sample of Canadian secondary school students from the COMPASS study
(Elsevier, 2021-06)Introduction Intramurals in schools may encourage physical activity among youth. Schools are continuously making changes to these intramurals, yet it is not well understood how these changes impact youth physical activity. ... -
A quasi-experimental study of a mandatory calorie-labelling policy in restaurants: Impact on use of nutrition information among youth and young adults in Canada
(Elsevier, 2018-11-01)In 2017, Ontario became the first Canadian province to require calorie amounts on menus/menu boards of chain restaurants. The province of British Columbia (BC) implemented a voluntary nutrition information initiative in ... -
Quasi-static and dynamic characterization of unidirectional non-crimp carbon fiber fabric composites processed by HP-RTM
(Elsevier, 2019-07)Recently developed high-pressure resin transfer molding (HP-RTM) processes have enabled the integration of lightweight fiber-reinforced composites into automobiles (e.g., frame and roof components, floor segments), which ... -
Quotient Complexities of Atoms in Regular Ideal Languages
(Institute of Informatics: University of Szeged, 2015)A (left) quotient of a language L by a word w is the language w(-1) L = {x vertical bar wx is an element of L}. The quotient complexity of a regular language L is the number of quotients of L; it is equal to the state ... -
Quotient Complexity of Bifix-, Factor-, and Subword-Free Regular Language
(Institute of Informatics: University of Szeged, 2014)A language $L$ is prefix-free if whenever words $u$ and $v$ are in $L$ and $u$ is a prefix of $v$, then $u=v$. Suffix-, factor-, and subword-free languages are defined similarly, where by ``subword" we mean ``subsequence", ... -
Quotient Complexity Of Closed Languages
(Springer, 2014-02-01)A language L is prefix-closed if, whenever a word w is in L, then every prefix of w is also in L. We define suffix-, factor-, and subword-closed languages in an analogous way, where by factor we mean contiguous subsequence, ... -
Quotient Complexity of Ideal Languages
(Elsevier, 2013-01-28)A language L over an alphabet Σ is a right (left) ideal if it satisfies L=LΣ∗ (L=Σ∗L). It is a two-sided ideal if L=Σ∗LΣ∗, and an all-sided ideal if L=Σ∗L, the shuffle of Σ∗ with L. Ideal languages are not only of interest ... -
