Passivity-Based Control of Sampled-Data Systems on Lie Groups with Linear Outputs
(Elsevier, 2016-12-22)We present a method of stabilizing a sampled-data system that evolves on a matrix Lie group using passivity. The continuous-time plant is assumed passive with known storage function, and its passivity is preserved under ... -
Password Advice Shouldn't Be Boring: Visualizing Password Guessing Attacks
(IEEE, 2013-09)Users are susceptible to password guessing attacks when they create weak passwords. Despite an abundance of text-based password advice, it appears insufficient to help home users create strong memorable passwords. We propose ... -
Path analysis of warning label effects on negative emotions and quit attempts: A longitudinal study of smokers in Australia, Canada, Mexico, and the US
(Elsevier, 2018-01-01)Background Cigarette pack health warning labels can elicit negative emotions among smokers, yet little is known about how these negative emotions influence behavior change. Objective Guided by psychological theories ... -
Path Following for Mobile Manipulators
(Springer, 2017-07-25)This paper presents a framework of path following via set stabilization for mobile manipulator systems. The mobile manipulator is modelled as a single redundant dynamic system. The mobile base considered belongs to a large ... -
Path following using dynamic transverse feedback linearization for car-like robots
(IEEE, 2015-02-16)This paper presents an approach for designing path following controllers for the kinematic model of car-like mobile robots using transverse feedback linearization with dynamic extension. This approach is applicable to ... -
A path integral ground state replica trick approach for the computation of entanglement entropy of dipolar linear rotors
(AIP Publishing, 2020-05-14)We calculate the second Rényi entanglement entropy for systems of interacting linear rotors in their ground state as a measure of entanglement for continuous rotational degrees of freedom. The entropy is defined in relation ... -
A path integral methodology for obtaining thermodynamic properties of nonadiabatic systems using Gaussian mixture distributions
(American Institute of Physics, 2018-05)We introduce a new path integral Monte Carlo method for investigating nonadiabatic systems in thermal equilibrium and demonstrate an approach to reducing stochastic error. We derive a general path integral expression for ... -
Pathways and Processes: Reviewing the Role of Young Adults in Urban Structure
(Taylor and Francis, 2017-03-31)Challenges arising from changing demographics, expensive housing, and precarious labor have prompted recent interest in the residential geographies of young adults. Yet, despite attention to young adults' diverse housing ... -
Pathways of Influence: Understanding the Impacts of Philosophy of Science in Scientific Domains
(Springer, 2021-03-22)Philosophy of science has the potential to improve scientific practice, science policy, and science education; moreover, recent research indicates that many philosophers of science think we ought to increase the broader ... -
Patterns of Search Result Examination: Query to First Action.
(ACM, 2019-11-03)To determine key factors that affect a user's behavior with search results, we conducted a controlled eye-tracking study of users completing search tasks using both desktop and mobile devices. We focus our investigation ... -
PDF Accessibility: Considerations and Best Practices for Learning Objects and Other Library Materials
(University of Waterloo Library, 2022-03-30)Despite concerns raised about accessibility compliance, libraries and vendors still commonly create and use PDFs for information sharing and information literacy instruction, a trend heightened by the recent increase in ... -
PEGylated MoSe2 Nanomaterials with Limited Oxidation via Femtosecond Laser Ablation for Photothermal Therapy
(American Chemical Society, 2024)MoSe2 nanomaterials are promising photothermal agents for non-invasive cancer treatment. Their surfaces usually need to be functionalized with biocompatible polymers to improve their biocompatibility and colloidal stability ... -
Penalized Regression for Interval-Censored Times of Disease Progression: Selection of HLA Markers in Psoriatic Arthritis
(Wiley, 2015-09)Times of disease progression are interval-censored when progression status is only known at a series of assessment times. This situation arises routinely in clinical trials and cohort studies when events of interest are ... -
Peptide and peptide-carbon nanotube hydrogels as scaffolds for tissue & 3D tumor engineering
(Elsevier, 2018-03-15)The use of hybrid self-assembling peptide (EFK8)-carbon nanotube (SWNT) hydrogels for tissue engineering and in vitro 3D cancer spheroid formation is reported. These hybrid hydrogels are shown to enhance the attachment, ... -

Perceived Gaze Direction Differentially Affects Discrimination of Facial Emotion, Attention, and Gender – An ERP Study
(Frontiers, 2019-05-24)The perception of eye-gaze is thought to be a key component of our everyday social interactions. While the neural correlates of direct and averted gaze processing have been investigated, there is little consensus about how ... -
Perceived timing of active head movement at different speeds
(Elsevier, 2018-11-20)The central nervous system must determine which sensory events occur at the same time. Actively moving the head corresponds with large changes in the relationship between the observer and the environment, sensorimotor ... -
The percentage of DHA in erythrocytes can detect non-adherence to advice to increase EPA and DHA intakes
(Cambridge University Press, 2014-01-28)Characterisation of long-term adherence to EPA and DHA intakes through biomarkers and dietary assessments has implications for interpreting the findings of long-term intervention studies. Adherence to dietary advice targeting ... -
Performance Limit Projection of Germanane Field-Effect Transistors
(Institute of Electrical and Electronics Engineers, 2017-03-13)Here we explore the performance limit of monolayer germanane (GeH) field-effect transistors (FETs). We first plotted an electronic band structure of GeH using density functional theory (DFT) and then tight-binding parameters ... -
Performance of Brain-Computer Interfacing Based on Tactile Selective Sensation and Motor Imagery
(Institute of Electrical and Electronics Engineers, 2017-11-03)A large proportion of users do not achieve adequate control using current non-invasive Brain-computer Interfaces (BCI). This issue has being coined “BCI-Illiteracy”, and is observed among BCI modalities. Here, we compare ...
