Links between Surface Changes with Strain whitening, Shear Banding and Damage in a Toughened Epoxy Adhesive
(Taylor & Francis, 2021-02-24)Owing to the increased use of toughened epoxy adhesives in current transportation light weighting efforts, it is critical that the damage mechanisms observable as strain whitening in these materials are understood and ... -
Liposome Supported Metal Oxide Nanoparticles: Interaction Mechanism, Light Controlled Content Release and Intracellular Delivery
(Wiley, 2014-05-26)Zwitterionic phosphotydylcholine liposomes stably adsorb a number of metal oxide nanoparticles via its phosphate group. This is different from physisorption and fusion with SiO2. The hybrid materials can be internalized ... -
Liposome/Graphene Oxide Interaction Studied by Isothermal Titration Calorimetry
(American Chemical Society, 2015-03-15)The interaction between graphene oxide (GO) and lipid bilayers is important for fundamental surface science and many applications. In this work, isothermal titration calorimetry (ITC), cryo-TEM, and fluorescence spectroscopy ... -
Liquid metal embrittlement in laser lap joining of TWIP and medium-manganese TRIP steel: The role of stress and grain boundaries
(Elsevier, 2018-11-01)High-Manganese austenite-containing steels with superior combination of strength and ductility have shown potential for enhancement of passenger safety and body-in-white (BIW) weight reduction. Even though Zn-coated ... -
List 3-Coloring Graphs with No Induced P6+rP3
(Springer Nature, 2021-01-01)For an integer t, we let Pt denote the t-vertex path. We write H+G for the disjoint union of two graphs H and G, and for an integer r and a graph H, we write rH for the disjoint union of r copies of H. We say that a graph ... -
List 3-coloring Pt-free graphs with no induced 1-subdivision of K1,s
(Elsevier, 2020-11)Let s and t be positive integers. We use Pt to denote the path with t vertices and K1,s to denote the complete bipartite graph with parts of size 1 and s respectively. The one-subdivision of K1,s is obtained by replacing ... -
Load path sensitivity and fatigue life estimation of 30CrNiMo8HH
(Elsevier, 2012-04-01)A set of strain-controlled biaxial proportional and non-proportional tests were conducted on solid and tubular specimens of 30CrNiMo8HH steel. The effect of the phase angle on fatigue life was studied. This effect becomes ... -
Load-sharing and kinematics of the human cervical spine under multi-axial transverse shear loading: combined experimental and computational investigation
(National Library of Medicine, 2021-06)The cervical spine experiences shear forces during everyday activities and injurious events yet there is a paucity of biomechanical data characterizing the cervical spine under shear loading. This study aimed to 1) ... -
Local nested transverse feedback linearization
(Springer, 2015-08-29)We study two local feedback equivalence problems for a nonlinear control-affine system with two nested, controlled-invariant, embedded submanifolds in its state space. The first, less restrictive, result gives necessary ... -
Local observers on linear Lie groups with linear estimation error dynamics
(IEEE, 2014-03-06)This technical note proposes local exponential observers for systems on linear Lie groups. We study two classes of systems. In the first class, the full state of the system evolves on a linear Lie group and is available ... -
A Local Solution to the Output Regulation Problem for Sampled-Data Systems on Commutative Matrix Lie Groups
(IEEE, 2018-08-16)We present a smooth nonlinear control law for a kinematic plant on commutative matrix Lie groups that achieves regulation, if the state tracking and estimation errors are initialized in a suitable neighbourhood of identity. ... -
Local synchronization of sampled-data systems on one-parameter Lie subgroups
(IEEE, 2017-07-03)We present a distributed nonlinear control law for synchronization of identical agents on one-parameter Lie subgroups. If the agents are initialized sufficiently close to one another, then synchronization is achieved ... -
Local transverse feedback linearization for nested sets
(IEEE, 2016-02-11)We study a local feedback equivalence problem for a nonlinear control-affine system with two nested, controlled invariant, embedded submanifolds in its state space. The main result of this paper gives necessary and sufficient ... -
Locally-Adaptive Tabulation of Low-Dimensional Manifolds using Bezier Patch Reconstruction
(2017-05-17)An efficient tabulation strategy for turbulent combustion simulations is proposed. Using a locally adaptive arrangement of structured Bezier patches–often used in computer graphics–the combustion manifold can be efficiently ... -
Long Range Polymer Chain Dynamics Studied by Fluorescence Quenching
(American Chemical Society, 2016-09-13)Over the years, fluorescence quenching experiments have provided a robust analytical means to retrieve information about the internal dynamics of macromolecules in general and the long range polymer chain dynamics (LRPCD) ... -
Long-distance Movement over a Period of Days by a Female Myotis lucifugus in Newfoundland, Canada
(Humboldt Field Research Institute, 2021-02)Myotis lucifugus (Little Brown Myotis) is a regionally migrating bat, widely distributed throughout North America. Through long-term monitoring systems deployed in 2 locations in Newfoundland, Canada, we recorded the ... -
Long-Range, Polymer Chain Dynamics of a "Stiff" Polymer. Fluorescence from Poly(isobutylene-alt-maleic anhydride) with N-(1-Pyrenylmethyl)succinimide Groups
(American Chemical Society, 2017-04-25)The steady-state fluorescence (SSF) spectra and time resolved fluorescence (TRF) decays of five poly(isobutylene-alt-maleic anhydride) copolymers (PIMA), randomly labeled with N-(1-pyrenyl methyl)succinimide groups (Py-PIMA), ... -
Long-term Average Cost in Featured Transition Systems
(ACM, 2016-09)A software product line is a family of software products that share a common set of mandatory features and whose individual products are differentiated by their variable (optional or alternative) features. Family-based ... -
Long-term implantation of acoustic transmitters induces chronic inflammatory cytokine expression in adult rainbow trout (Oncorhynchus mykiss)
(Elsevier, 2018-11-01)Telemetry transmitters are frequently used in studies of wild fish migration and behavior. Although the effects of surgically implanted transmitters on survival, tag retention, healing and growth have been studied, there ... -
A longitudinal evaluation of food safety knowledge and attitudes among Ontario high school students following a food handler training program
