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 ... -
An Open-Source Strategy for Documenting Events: The Case Study of the 42nd Canadian Federal Election on Twitter
(Code4Lib, 2016-04-25)This article examines the tools, approaches, collaboration, and findings of the Web Archives for Historical Research Group around the capture and analysis of about 4 million tweets during the 2015 Canadian Federal Election. ... -
Operational maps between molecular properties and environmental stress cracking resistance (ESCR)
(Wiley, 2019-01-20)Environmental stress cracking (ESC) is one of the main failure mechanisms involved in polymer fractures. This paper focusses on the environmental stress cracking resistance (ESCR) of polyethylene (PE) in which ESC occurs ... -
OPERATORS WHICH ARE POLYNOMIALLY ISOMETRIC TO A NORMAL OPERATOR
(American Mathematical Society, 2020-01-15)Let H be a complex, separable Hilbert space and B(H) denote the algebra of all bounded linear operators acting on H. Given a unitarily-invariant norm k · ku on B(H) and two linear operators A and B in B(H), we shall say ... -
Opposing effects of cationic antimicrobial peptides and divalent cations on bacterial lipopolysaccharides
(American Physical Society, 2017-10-09)The permeability of the bacterial outer membrane, enclosing Gram-negative bacteria, depends on the interactions of the outer, lipopolysaccharide (LPS) layer, with surrounding ions and molecules. We present a coarse-grained ... -
Optimal Actuator Location for Semi-Linear Systems
(2018)Actuator location and design are important choices in controller design for distributed parameter systems. Semi-linear partial differential equations model a wide spectrum of physical systems with distributed parameters. ... -
Optimal Controller and Actuator Design for Nonlinear Parabolic Systems
(2019-10-08)Many physical systems are modeled by nonlinear parabolic differential equations, such as the Kuramoto-Sivashinsky (KS) equation. In this paper, the existence of a concurrent optimal controller and actuator design is ... -
Optimal energy-efficient predictive controllers in automotive air-conditioning/refrigeration systems
(Elsevier, 2016-12-15)This paper presents several robust model predictive controllers that improve the temperature performance and minimize energy consumption in an automotive air-conditioning/refrigeration (A/C-R) system with a three-speed and ... -
An optimal gear-shifting strategy for heavy trucks with trade-off study between trip time and fuel economy
(Inderscience, 2015-11-27)We show how the fuel efficiency of heavy mining trucks can be improved by optimising the gear-shifting strategy. Using characteristic tests of the diesel engine, a high-fidelity model of a mining truck was built in MapleSim ... -
Optimal generic attack against basic Boneh-Boyen signatures
(Springer-Verlag, 2022-11-19)The Boneh-Boyen digital signature scheme is a pairing-based signature scheme that features short signatures consisting of one group element, the minimum possible size. In contrast to earlier short signature schemes such ... -
Optimal inventory decisions for a risk-averse retailer when offering layaway
(Elsevier, 2020-07-01)Layaway allows economically disadvantaged budget-constrained consumers to purchase expensive items through amortized payments and nominal program fees, as opposed to using high-interest financing options such as credit ... -
Optimal inventory decisions when offering layaway
(Taylor & Francis, 2019)This paper presents an inventory management policy for a retailer offering a layaway programme. Layaway is a service provided by retailers that allows budget constrained consumers who have sufficiently high valuations to ... -
Optimal Investing Strategies for Participating Contracts
(Elsevier, 2017-03)Participating contracts are popular insurance policies, in which the payoff to a policyholder is linked to the performance of a portfolio managed by the insurer. We consider the portfolio selection problem of an insurer ... -
Optimal investment-reinsurance strategies with state dependent risk aversion and VaR constraints in correlated markets
(Elsevier, 2019-03)In this paper, we investigate the optimal time-consistent investment–reinsurance strategies for an insurer with state dependent risk aversion and Value-at-Risk (VaR) constraints. The insurer can purchase proportional ...
