On the optimal CFL number of SSP methods for hyperbolic problems
(Elsevier, 2019-01-01)We show that the theory for strong stability preserving (SSP) time stepping methods employed with the method of lines-type discretizations of hyperbolic conservation laws may result in overly stringent time step restrictions. ... -
On the Road to Making Science of “Art”: Risk Bias in Market Scoring Rules
(The Institute for Operations Research and the Management Sciences, 2018-06)We study market scoring rule (MSR) prediction markets in the presence of risk-averse or risk-seeking agents that have unknown yet bounded risk preferences. It is well known that if agents can be prescreened, then MSRs can ... -
On the role of the microporous layer in PEMFC operation
(Elsevier, 2009-03-01)The condition of liquid water breakthrough at the cathode of polymer electrolyte fuel cells (PEMFC) is studied experimentally and data on corresponding water saturation and capillary pressure are provided for gas diffusion ... -
On the sensitivity of modelled groundwater recharge estimates to rain gauge network scale
(Elsevier, 2020-06-01)Rainfall is often the largest component of the water budget and even a small uncertainty percentage may lead to challenges for accurately estimating groundwater recharge as a calculated residual within a water budget ... -
On the spectrum of the Sylvester-Rosenblum operator acting on triangular algebras
(Ele-Math, 2020)Let A and B be algebras and M be an A -B-bimodule. For A ∈ A , B ∈B, we define the Sylvester-Rosenblum operator τA,B :M →M via τA,B(M) = AM+MB for all M ∈ M . We investigate the spectrum of τA,B in three settings, namely: ... -
On the TVD property of second order methods for 2D scalar conservation laws
(arXiv, 2021-10-05)The total variation diminishing (TVD) property is an important tool for ensuring nonlinear stability and convergence of numerical solutions of one-dimensional scalar conservation laws. However, it proved to be challenging ... -
On the use of physical boundary conditions for two-phase flow simulations: Integration of control feedback
(Elsevier, 2018-10-04)The sensitivity of two-phase flow simulations using the Euler–Euler model on the inlet boundary conditions (BCs) is studied. Specifically, the physical relevance of Dirichlet uniform inlet velocity BCs is studied which are ... -
On-chip cell lysis by antibacterial non-leaching reusable quaternary ammonium monolithic column
(Springer US: Biomedical Microdevices, 2015-12-16)Reusable antibacterial non-leaching monolithic columns polymerized in microfluidic channels designed for on-chip cell lysis applications were obtained by the photoinitiated free radical copolymerization of diallyldimethylammonium ... -
Once you get them, how do you keep them? Millennial librarians at work
(Emerald, 2010)Purpose: To draw attention to the unique characteristics of Millennial librarians. These characteristics are related to larger issues having current and future relevance to Millennial librarians, colleagues of other ... -
One box to search them all: Implementing federated search at an academic library
(Emerald, 2009)Purpose: The purpose of this paper is to present how, in May 2008, the Ad Hoc Committee on Federated Search was formed to prepare a preliminary report on federated searching for a special meeting of Librarians Academic ... -
One versus two eyes makes a difference! Early face perception is modulated by featural fixation and feature context
(Elsevier, 2018-12-01)The N170 event-related potential component is an early marker of face perception that is particularly sensitive to isolated eye regions and to eye fixations within a face. Here, this eye sensitivity was tested further by ... -
One-Dimensional Population Density Approaches To Recurrently Coupled Networks Of Neurons With Noise
(Society for Industrial and Applied Mathematics, 2015)Mean-field systems have been previously derived for networks of coupled, two-dimensional, integrate-and-fire neurons such as the Izhikevich, adapting exponential, and quartic integrate-and-fire, among others. Unfortunately, ... -
One-pot synthesis of porous silica-supported ultrafine Ni nanoparticles as efficient and stable catalyst for selective hydrogenation of benzophenone
(Elsevier, 2019-12-15)In this work, we report a silica-supported ultrafine Ni catalyst for the selective hydrogenation of benzophenone. This material was developed by a facile one-pot co-assembly syntheses strategy, using Ni(II) chelated alginate ... -
Online mapping of EMG signals into kinematics by autoencoding
(Biomed Central, 2018-03-13)Background: In this paper, we propose a nonlinear minimally supervised method based on autoencoding (AEN) of EMG for myocontrol. The proposed method was tested against the state-of-the-art (SOA) control scheme using a ... -
Open Data’s Potential for Political History
(Canadian Parliamentary Review, 2014)The recent trend of “open government” initiatives has provided an exciting new source of material for digital humanities researchers. Large datasets allow these scholars to engage in “distant reading” exercises to provide ... -
Open Port Probe Sampling Interface for the Direct Coupling of Biocompatible Solid-Phase Microextraction to Atmospheric Pressure Ionization Mass Spectrometry
(American Chemical Society, 2017-04-04)In recent years, the direct coupling of solid phase microextraction (SPME) and mass spectrometry (MS) has shown its great potential to improve limits of quantitation, accelerate analysis throughput, and diminish potential ... -
Open Shortest Path First Routing Under Random Early Detection
(Wiley, 2018-03-01)In this article, we consider a variant of Open Shortest Path First (OSPF) routing that accounts for Random Early Detection (RED), an Active Queue Management method for backbone networks. In the version of OSPF we consider ... -
