Role of Artificial Intelligence in Theranostics: Toward Routine Personalized Radiopharmaceutical Therapies
(Elsevier, 2021-10)KEY POINTS AI has shown promising applications in quantitative imaging required for dosimetry. Segmentation of organs and tumors, the most time consuming task in the dosimetry workflow, can be automated using AI. ... -
Clinical Applications of Artificial Intelligence in positron emission tomography of Lung Cancer
(Elsevier, 2022-01)The ability of a computer to perform tasks normally requiring human intelligence or artificial intelligence (AI) is not new. However, until recently, practical applications in medical imaging were limited, especially in ... -
Induced subgraphs and tree decompositions II. Toward walls and their line graphs in graphs of bounded degree.
(Elsevier, 2024-01)This paper is motivated by the following question: what are the unavoidable induced subgraphs of graphs with large treewidth? Aboulker et al. made a conjecture which answers this question in graphs of bounded maximum ... -
Induced subgraphs and tree decompositions VII. Basic obstructions in H-free graphs.
(Elsevier, 2024-01)We say a class C of graphs is clean if for every positive integer t there exists a positive integer w(t) such that every graph in C with treewidth more than w(t) contains an induced subgraph isomorphic to one of the ... -
Biomechanical analysis of the pelvic floor and pessary device design
(University of Waterloo, 2023-11-21)Pelvic floor disorders (PFD) including pelvic organ prolapse (POP) can significantly impact women’s quality of life. Pessaries, removable gynecological prosthetic devices, provide mechanical support for temporary or long-term ... -
Planting Imagination: Community Co-Design for Chinatown Toronto | Impact Report
(University of Waterloo, 2023-07)Planting Imagination ran from April 2021 to March 2023 (during a pandemic recovery period) in Toronto’s Chinatown West neighbourhood. It brought together a group of local Chinatown community organizations and Toronto ... -
Manufacturing of a Fiber-Reinforced Thermoplastic Composite Micro-Generating Wind Turbine Blade
(University of Waterloo, 2023-11-20)In response to climate legislation attempting to curb global greenhouse emissions, renewable energy technologies have seen rapidly increasing global demand over the past two decades, with significant attention paid to the ... -
Update-Aware Information Extraction
(University of Waterloo, 2023-11-20)Information extraction programs (extractors) can be applied to documents to isolate structured versions of some content by creating tabular records corresponding to facts found in the documents. When extracted relations ... -
Widening the View: A Standardized Approach to Capturing Family Members’ Perspectives on Quality of Life in Long-term Care
(University of Waterloo, 2023-11-20)Background and Rationale: Family members provide important functional and socio-emotional support to residents living in Long-Term Care (LTC). With high rates of cognitive impairment among residents, family member input ... -
Application of Stereo-Depth Camera and Alignment Algorithms for Part Monitoring During Machining
(University of Waterloo, 2023-11-20)A stereo-depth camera is proposed to be used in conjunction with fiducial markers on a calibration plate and a fine-tuning alignment algorithm for part monitoring in a CNC machine. Together, a selected pyramid-shaped ... -
Simulated Annealing Reconstruction and Effective Transport Properties of PEM Fuel Cell Catalyst Layers
(University of Waterloo, 2023-11-15)A proton exchange membrane fuel cell (PEMFC) is an energy-conversion device that can be used in a wide variety of applications and is considered a promising alternative to gas and diesel engines for vehicular purposes. ... -
Neutron Scattering Investigations of Three-Dimensional Topological States
(University of Waterloo, 2023-11-13)Topological magnets represent a unique class of quantum materials in which a nontrivial Berry curvature in real- or momentum-space couples to the magnetic properties of the topological electronic or spin system. Magnetic ... -
Considerations regarding Incorporating a Cash-for-care Program in Ontario's Approach to Care for Older Adults
(University of Waterloo, 2023-11-13)Ontario, like Canada more generally, has an aging population, which will exert further pressures on the approaches to providing care to older persons. Certain of these pressures are outlined, with the aid of population ... -
Modelling the Subglacial Hydrology of Trinity-Wykeham Glaciers of the Northern Canadian Arctic
(University of Waterloo, 2023-11-09)In Canada’s High Arctic region, the melting of glacial ice contributes substantially to the world’s increasing sea levels (Harig and Simons, 2016). Of the icebergs in the region, approximately 62% are discharged by ... -
Analysis of the optimal time to withdraw investments from hedge funds with alternative fee structures
(Oxford Academic, 2022-04)We study the optimal stopping problem arising from an investor determining the optimal time to withdraw from a hedge fund investment with a shared loss fee structure and a positive fee for assets under management. The ... -
The Reinforcement Learning Kelly Strategy
(Taylor & Francis, 2022-03)The full Kelly portfolio strategy's deficiency in the face of estimation errors in practice can be mitigated by fractional or shrinkage Kelly strategies. This paper provides an alternative, the RL Kelly strategy, based on ... -
Mean-Expectile Portfolio Selection
(Springer, 2021)We consider a mean-expectile portfolio selection problem in a continuous-time diffusion model. We exploit the close relationship between expectiles and the Omega performance measure to reformulate the problem as the ... -
Lower Tail Independence of Hitting Times of Two-Dimensional Diffusions
(Cambridge University Press, 2018)The coefficient of tail dependence is a quantity that measures how extreme events in one component of a bivariate distribution depend on extreme events in the other component. It is well known that the Gaussian copula has ... -
Dynamic Hedging Strategies for Cash Balance Pension Plans
(Cambridge University Press, 2018-09)Cash balance pension plans with crediting rates linked to long bond yields are relatively common in the United States, but their liabilities are proving very challenging to hedge. In this paper, we consider dynamic hedge ... -
Fair Transition from Defined Benefit to Target Benefit
(Cambridge University Press, 2021)Target benefit (TB) plans that incorporate intergenerational risk sharing have been demonstrated to be welfare improving over the long term. However, there has been little discussion of the short-term benefits for members ...
