Low-cycle fatigue characterization and texture induced ratcheting behaviour of forged AZ80 Mg alloys
(Elsevier, 2018-11-01)Stress-controlled uniaxial “push-pull” fatigue testing was conducted on as-received (cast and extruded) and closed-die cast-forged and extruded-forged AZ80 Mg alloy. The as-cast material possessed random texture and somewhat ... -
A low-power dynamic comparator for low-offset applications
(Elsevier, 2019-11)In this paper, a low-power method for double-tail comparators is introduced. Using the proposed method, the power consumption of the pre-amplifier which is the dominant part is reduced considerably. Thanks to this method, ... -
A lower bound for the two-variable Artin conjecture and prime divisors of recurrence sequences
(Elsevier, 2019-01-01)In 1927, Artin conjectured that any integer other than −1 or a perfect square generates the multiplicative group (Z/pZ)× for infinitely many p. In 2000, Moree and Stevenhagen considered a two-variable version of this ... -
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 ... -
Lysis of Gram-positive and Gram-negative Bacteria by Antibacterial Porous Polymeric Monolith Formed in Microfluidic Biochips for Sample Preparation
(Springer-Verlag Berlin Heidelberg: Analytical and Bioanalytical Chemistry, 2014-07-25)Bacterial cell lysis is demonstrated using polymeric microfluidic biochips operating via a hybrid mechanical shearing/contact killing mechanism. These biochips are fabricated from a cross-linked poly(methyl methacrylate) ... -
M-current induced Bogdanov–Takens bifurcation and switching of neuron excitability class
(Springer, 2021-02-15)In this work, we consider a general conductance-based neuron model with the inclusion of the acetycholine sensitive, M-current. We study bifurcations in the parameter space consisting of the applied current Iapp, the maximal ... -
Machine Learning in the Nuclear Medicine: Part 1-Introduction
(Society of Nuclear Medicine and Molecular Imaging, 2019-04)This article, the first in a 2-part series, provides an introduction to machine learning (ML) in a nuclear medicine context. This part addresses the history of ML and describes common algorithms, with illustrations of when ... -
Machine Learning in the Nuclear Medicine: Part 2-Neural Networks and Clinical Aspects
(Society of Nuclear Medicine and Molecular Imaging, 2021-01)This article is the second part in our machine learning series. Part 1 provided a general overview of machine learning in nuclear medicine. Part 2 focuses on neural networks. We start with an example illustrating how neural ... -
MachSMT: A Machine Learning-based Algorithm Selector for SMT Solvers
(2020)In this paper, we present MachSMT, an algorithm selection tool for state-of-the-art Satisfiability Modulo Theories (SMT) solvers. MachSMT supports the entirety of the logics within the SMT-LIB initiative. MachSMT uses ... -
Magnetic Iron Oxide Nanoparticle Seeded Growth of Nucleotide Coordinated Polymers
(American Chemical Society, 2016-06-22)The introduction of functional molecules to the surface of magnetic iron oxide nanoparticles (NPs) is of critical importance. Most previously reported methods were focused on surface ligand attachment either by physisorption ... -
Magnetic nano-nets for capture of microbes in solution based on physical contact
(Elsevier, 2019-02-01)Self-assembly of Au nanoparticles with Fe ions is used to develop magnetic nano-nets similar to fishing nets for capture and removal of microbes in aqueous medium. The nano-nets have a high aspect ratio, span microns in ... -
Magnetoconductance due to variable-range hopping in quasi-two-dimensional systems: Application to PrBa2Cu3O7-delta
(American Physical Society, 1998-01)In this paper, we have developed a theory of magnetoconductance (magnetoresistance) due to variable-range hopping for quasi-two-dimensional systems. We have included the effect of electric fields on the calculation of the ... -
Maize and precolonial Africa
(Elsevier, 2019-01-01)Columbus's arrival in the New World triggered an unprecedented movement of people and crops across the Atlantic Ocean. We study a largely overlooked part of this Columbian Exchange: the effects of New World crops in Africa. ... -
Major liver resection, systemic fibrinolytic activity, and the impact of tranexamic acid
(Elsevier, 2016-12-01)Background: Hyperfibrinolysis may occur due to systemic inflammation or hepatic injury that occurs during liver resection. Tranexamic acid (TXA) is an antifibrinolytic agent that decreases bleeding in various settings, but ... -
Makers and Quilters: Investigating Opportunities for Improving Gender-Imbalanced Maker Groups
(ACM, 2019-11)Recent efforts to diversify participation in STEM (Science, Technology, Engineering & Math) activities through informal learning environments, such as hackathons and makerspaces, confirm a real desire for inclusion among ... -
Making Connections at the Personal & Curricular Levels
(2013-04-19)Making personal connections and building relationships. Connecting people to information at points of need is at the heart of what we do. As Health Sciences Liaison Librarians at the University of Waterloo, these Librarians ... -
Making sense of precarity: talking about economic insecurity with millennials in Canada
(Taylor & Francis, 2019)While there are many effective metrics for quantifying economic precarity, talking to young people about their experiences in the labour and housing markets reveals a gap in explanatory language around living in/through ... -
