Transverse Feedback Linearization with Partial Information for Single-Input Systems
(SIAM, 2014-09-25)This paper is motivated by the problem of asymptotically stabilizing invariant sets in the state space of control systems by means of output feedback. The sets considered are smooth embedded in submanifolds and the class ... -
Treating Cell Culture Media with UV Irradiation against Adventitious Agents: Minimal Impact on CHO Performance
(Wiley, 2014-10-01)Sterility of cell culture media is an important concern in biotherapeutic processing. In large scale biotherapeutic production, a unit contamination of cell culture media can have costly effects. Ultraviolet (UV) irradiation ... -
Trends in youth cannabis use across cannabis legalization: Data from the COMPASS prospective cohort study
(Elsevier, 2021-06)Canada legalized recreational cannabis use for adults on October 17, 2018 with decision-makers emphasising the need to reduce cannabis use among youth. We sought to characterise trends of youth cannabis use before and after ... -
Triangle-free graphs that do not contain an induced subdivision of K4 are 3-colorable
(Wiley, 2019-10)We show that triangle-free graphs that do not contain an induced subgraph isomorphic to a subdivision of K4 are 3-colorable. This proves a conjecture of Trotignon and Vušković. -
Triangle-free graphs with no six-vertex induced path
(Elsevier, 2018-08)The graphs with no five-vertex induced path are still not understood. But in the triangle-free case, we can do this and one better; we give an explicit construction for all triangle-free graphs with no six-vertex induced ... -
Triangular Epistolary Diplomacy with Rome from Judas Maccabee to Aristobulos I
(Société Latomus, Brussels, 2020-05-18)Scholarly opinions tend to converge towards accepting that Roman commitment to Judaea was very limited: sources attesting treaties of friendship and alliance are either seen as fabricated or not reflecting the real ... -
Truncation selection and diffusion on random graphs
(Arxiv, 2017-08-31)Two-strategy evolutionary games on graphs have been extensively studied in the literature. A variety of graph structures, degrees of graph dynamics, and behaviours of replicators have been explored. These models have ... -
Tunable covalent organic framework electrochemiluminescence from non-electroluminescent monomers
(Elsevier, 2021-10)It is hard to find new electrochemiluminescence (ECL) luminophores using existing research strategies, especially from ECL non-active monomers. Here, fully conjugated covalent organic frameworks with trithiophene (BTT-COFs) ... -
Tunnel Divisions: Interactive Sound Mapping of Transitory Public Spaces
(ACM, 2016-11-06)We present Tunnel Divisions, an interactive musical installation designed for ephemeral interaction in public spaces. Informed by concepts from cultural and media studies along with existing literature on interactive public ... -
Tweets and transitions: Exploring Twitter-based political discourse regarding energy and electricity in Ontario, Canada
(Elsevier, 2021-02-01)The article explores how Twitter data can inform the study of the socio-political dimensions of sustainability transitions. Twitter is a widely used microblogging platform that allows users to share short comments, media, ... -
Two centuries of nitrogen dynamics: Legacy sources and sinks in the Mississippi and Susquehanna River Basins
(American Geophysical Union, 2017-01-07)Global flows of reactive nitrogen (N) have increased significantly over the last century in response to agricultural intensification and elevated levels of atmospheric deposition. Despite widespread implementation conservation ... -
Two Pb2+-specific DNAzymes with opposite trends in split-site-dependent activity
(Royal Society of Chemistry, 2014-05-04)By splitting the catalytic core of DNAzymes into two halves, two Pb2+-specific DNAzymes retain partial activity, while they show opposite trends of activity as a function of the split site, revealing important nucleotides ... -
Two successive calcium-dependent transitions mediate membrane binding and oligomerization of daptomycin and the related antibiotic A54145
(Elsevier, 2016-09)Daptomycin and A54145 are homologous lipopeptide antibiotics that permeabilize the cell membranes of Gram-positive bacteria. Membrane permeabilization depends on the presence of both phosphatidylglycerol (PG) and calcium, ... -
Two weeks of docosahexaenoic acid (DHA) supplementation increases synthesis-secretion kinetics of n-3 polyunsaturated fatty acids compared to 8 weeks of DHA supplementation
(Elsevier, 2018-10)Docosahexaenoic acid (DHA, 22:6n-3) must be consumed in the diet or synthesized from n-3 polyunsaturated fatty acid (PUFA) precursors. However, the effect of dietary DHA on the metabolic pathway is not fully understood. ... -
A two-dimensional numerical model for glazing system thermal analysis
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1995-08)A simple two-dimensional (2-D) numerical control volume formulation is presented that can be used to model heat transfer through a vertical insulated glazing unit. This model accounts for natural convection of the fill gas ... -
A two-dimensional numerical model for natural convection in a vertical, rectangular window cavity
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1994-12-31)It is common for sealed glazing units to exhibit condensation problems when operated in cold climates. Condensation often forms along the perimeter of the exposed surface of the indoor glazing because of the thermal short ... -
A two-phase model for chronic disease processes under intermittent inspection
(Wiley, 2017-06-15)A model is developed for chronic diseases with an indolent phase that is followed by a phase with more active disease resulting in progression and damage. The time scales for the intensity functions for the active phase ... -
UCAnDoModels: A Context-based Model Editor for Editing and Debugging UML Class and State-Machine Diagrams
(ACM/IEEE, 2019-09)Practitioners face cognitive challenges when using model editors to edit and debug UML models, which make them reluctant to adopt modelling. To assist practitioners in their modelling tasks, we have developed effective ... -
Ultrahigh Nanoparticle Stability against Salt, pH, and Solvent with Retained Surface Accessibility via Depletion Stabilization
(American Chemical Society, 2012-06-20)For many applications, it is desirable to stabilize colloids over a wide range of buffer conditions while still retaining surface accessibility for adsorption and reaction. Commonly used charge or steric stabilization ... -
An Ultrasensitive Light-up Cu2+ Biosensor Using a New DNAzyme Cleaving a Phosphorothioate-Modified Substrate
(American Chemical Society, 2017-01-15)Cu2+ is a very important metal ion in biology, environmental science, and industry. Developing biosensors for Cu2+ is a key topic in analytical chemistry. DNAzyme-based sensors are highly attractive:, for their excellent ...
