19F NMR Monitoring of Reversible Protein Post‐Translational Modifications: Class D β‐Lactamase Carbamylation and Inhibition
(Wiley, 2019)Bacterial production of β‐lactamases with carbapenemase activity is a global health threat. The active sites of class D carbapenemases such as OXA‐48, which is of major clinical importance, uniquely contain a carbamylated ... -
Ab Initio Study of the CO–N2 Complex: a New Highly Accurate Intermolecular Potential Energy Surface and Rovibrational Spectrum
(2018-03-01)A new, highly accurate ab initio ground-state intermolecular potential-energy surface (IPES) for the CO-N2 complex is presented. Thousands of interaction energies calculated with the CCSD(T) method and Dunning’s aug-cc-pVQZ ... -
Automatic material classification via proprioceptive sensing and wavelet analysis during excavation
(IEEE, 2021-07-12)This paper presents an excavation material classification methodology that uses wavelet analysis and unsupervised learning on acceleration measurements. The technique was validated by using acceleration data that were ... -
Bench-marking on a national scale: the 2007 LibQUAL Canada experience
(2009-02-05)Preprint of paper given at the 2008 Library Assessment Conference, Seattle, Wash., Aug. 5, 2008 to be published in the conference proceedings. -
Boron: Its role in energy related research and applications
(Wiley, 2019)Boron’s unique position in the periodic table, i.e. at the apex of the line separating metals and nonmetals, makes it highly versatile in chemical reactions and applications. Contemporary demand for renewable and clean ... -
Chinese Cultural Factors Favouring Biotechnology Research
(Worldviews, 2009)This paper summarizes recent European research on social and cultural perceptions of biotechnology research, with a focus on transgenic mice. Secondly it attempts to consider some of the same questions from a Chinese ... -
Complex Viscosity of Star-Branched Macromolecules from Analytical General Rigid Bead-Rod Theory
(2021-07)The complex viscosity of planar star-branched polymers has been derived from general rigid bead-rod theory, but only for singly-beaded arms. Here, we explore the respective roles of branch functionality, arm length and ... -
Computing Excited OH Stretch States of Water Dimer in 12-D Using Contracted Intermolecular and Intramolecular Basis Functions
(2022-12-19)Due in part to the ubiquity and importance of water, water dimer has been intensively studied since it became possible to record its spectrum. Computing the (ro-)vibrational spectrum of water dimer is challenging. The water ... -
Computing vibrational spectra using a new collocation method with a pruned basis and more points than basis functions: avoiding quadrature
(2023-02-14)We present a new collocation method for computing the vibrational spectrum of a polyatomic molecule. Some form of quadrature or collocation is necessary when the potential energy surface does not have a simple form that ... -
Computing Vibration–Rotation-Tunnelling Levels of HOD Dimer
(2017)Using an accurate 6D water dimer potential energy surface, we compute vibration-rotation tunnelling levels of HOD dimer, by assuming that the two monomers are rigid. HOD dimer has two isomers, a D-bonded isomer and an ... -
Controllability and motion algorithms for underactuated Lagrangian systems on Lie groups
(IEEE, 2000)In this paper, we provide controllability tests and motion control algorithms for underactuated mechanical control systems on Lie groups with Lagrangian equal to kinetic energy. Examples include satellite and underwater ... -
Dearomatizing and Derivatizing a Mesityl Group on Boron by One‐Pot Photoisomerization and [4+2] Diels–Alder Addition
(Wiley, 2019)Boron compounds having a conjugated chelate backbone (N,C‐chelate or C,C‐chelate) and two mesityl substituents on boron have been found to undergo a facile one‐pot transformation/reaction with dienophiles, which leads to ... -
Decompositions of control systems on manifolds with an affine connection
(North-Holland, 1997)In this letter we present a decomposition for control systems whose drift vector field is the geodesic spray associated with an affine connection. With the geometric insight gained with this decomposition, we are able to ... -
Discussion on: ``Dynamic Sliding Mode Control for a Class of Systems with Mismatched Uncertainty''
(Lavoisier, 2005)This is an invited discussion paper on the paper ``Dynamic Sliding Mode Control for a Class of Systems with Mismatched Uncertainty'' by Xing-Gang Yan, Sarah K. Spurgeon, and Christopher Edwards, that will appear in the ... -
Efficiently Transforming from Values of a Function on a Sparse Grid to Basis Coefficients
(2021-10-11)In many contexts it is necessary to determine coefficients of a basis expansion of a function ${f}\left(x_1, \ldots, x_D\right) $ from values of the function at points on a sparse grid. Knowing the coefficients, one has ... -
An example with interesting controllability and stabilisation properties
(2005)A simple three-state system with two inputs is considered. The system's controllability is determined using properties of vector-valued quadratic forms. The quadratic structure is then used as the basis for the design of ... -
A Fluorescence‐Based Assay for Screening β‐Lactams Targeting the Mycobacterium tuberculosis Transpeptidase LdtMt2
(Wiley, 2019)Mycobacterium tuberculosis l,d‐transpeptidases (Ldts), which are involved in cell‐wall biosynthesis, have emerged as promising targets for the treatment of tuberculosis. However, an efficient method for testing inhibition ... -
Geometallurgical modeling of generic mineral processing plants
(Queen's University, 2020)A method to simulate mineral processing plants is developed for geometallurgical modeling. A modular simulation is implemented, thus each operation that comprises the process is programmed independently considering a ... -
A guide for pit optimization with pseudoflow in python
(Queen's University, 2020)The Pseudoflow algorithm is used to outline the ultimate pit limit by finding the maximum net value of the blocks extracted, while respecting precedences for their extraction. It works by modelling the blocks as a direct ... -
