Prevalence of Convergence Insufficiency-Type Symptomatology in Parkinson’s Disease
(Cambridge University Press, 2017-09)Background: Individuals with Parkinson’s disease (PD) often present with visual symptoms (e.g., difficulty in reading, double vision) that can also be found in convergence insufficiency (CI). Our objective was to estimate ... -
Pricing, greening, and transparency decisions considering the impact of government subsidies and CSR behavior in supply chain decisions
(Elsevier, 2021-05-01)In this paper, we analytically model different government subsidy strategies in a supply chain manufacturing and selling a green product. We model the interaction between greening degree and transparency level set by a ... -
A Prime Analogue of Roth's Theorem in Function Fields
(Springer New York, 2015)Abstract. Let Fq[t] denote the polynomial ring over the nite eld Fq, and let PR denote the subset of Fq[t] containing all monic irreducible polynomials of degree R. For non-zero elements r = (r1; r2; r3) of Fq satisfying ... -
A prime analogue of the Erdös-Pomerance conjecture for elliptic curves
(European Mathematical Society, 2005-12-31)Let E/Q be an elliptic curve of rank ≥ 1 and b ∈ E(Q) a rational point of infinite order. For a prime p of good reduction, let gb(p) be the order of the cyclic group generated by the reduction b of b modulo p. We denote ... -
Prime analogues of the Erdős–Kac theorem for elliptic curves
(Elseiver, 2006-08)Let E/Q be an elliptic curve. For a prime p of good reduction, let E(Fp) be the set of rational points defined over the finite field Fp. We denote by ω(#E(Fp)), the number of distinct prime divisors of #E(Fp). We prove ... -
Prime Divisors of the Number of Rational Points on Elliptic Curves with Complex Multiplication
(Wiley, 2005)Let E/Q be an elliptic curve. For a prime p of good reduction, let E(Fp) be the set of rational points defined over the finite field Fp. Denote by ω(#E(Fp)) the number of distinct prime divisors of #E(Fp). For an elliptic ... -
A priori discretization error metrics for distributed hydrologic modeling applications
(Elsevier, 2016-12-01)Watershed spatial discretization is an important step in developing a distributed hydrologic model. A key difficulty in the spatial discretization process is maintaining a balance between the aggregation-induced information ... -
Privatizing Security, Securitizing Policing: The Case of the G20 in Toronto, Canada
(Wiley, 2014-06)Allegations of police brutality, unlawful detention, and other breaches of civil liberties during the G20 in Toronto in June 2010 provide an important case through which to understand the changing nature of security and ... -
Probabilistic Fretting Fatigue Analysis of Bridge Stay Cables at Saddle Supports
(Taylor and Francis, 2020-01)Saddle systems have been used on recent projects to support the cables in cable-stayed and extradosed bridge structures. A major design consideration for these anchorage systems is the in-service fretting fatigue behaviour ... -
Probability distribution of the seismic damage cost over the life cycle of structures
(Elsevier, 2018-05-01)In the life-cycle analysis, the total cost of damage caused by earthquakes is a significant but highly uncertain component. In the current literature, the seismic risk analysis is largely limited to the evaluation of the ... -
Probing Side Chain Dynamics of Branched Macromolecules by Pyrene Excimer Fluorescence
(American Chemical Society, 2016-01-12)Four different pyrene-labeled polymers were prepared by radical copolymerization of n-butyl methacrylate (BMA) and 1-pyrenemethyl methacrylate (PyEG(0)-MA), 1-pyrenemethoxyethyl methacrylate (PyEG(1)-MA), 1-pyrene-methox ... -
Probing the Interactions between Mimics of Pour Point Depressants (PPDs) and Viscosity Index Improvers (VIIs) in Engine Oil Using Fluorescently Labeled PPDs
(American Chemical Society, 2019-03-18)The level of interpolymeric interactions experienced by a pyrene-labeled poly(octadecyl methacrylate) labeled with 6.7 mol% of 1-pyrenebutanol (Py(6.7)-PC18MA) was characterized by fluorescence in the presence of an amorphous ... -
Probing the Role of Internalized Geometric Strain on Heterogeneous Electrocatalysis
(American Chemical Society, 2019-09-09)The chemistry underlying the activation of nickel hydroxide toward electrocatalytic oxygen evolution by incorporation of iron remains a subject of debate. We extract insights into the role of geometric strain on the ... -
The Problem of History in the Age of Abundance
(The Chronicle of Higher Education, 2016-12-11)Our collective cultural heritage faces a serious problem: In the digital age, we can document and "remember" more than ever before. But the scale of historical material is so huge that it will decisively change how scholars ... -
A procedure for determining parameters of a simplified ligament model
(Elsevier, 2017-11-03)A previous mathematical model of ligament force-generation treated their behavior as a population of collagen fibres arranged in parallel. When damage was ignored in this model, an expression for ligament force in terms ... -
Procedure-specific Risks of Thrombosis and Bleeding in Urological Non-cancer Surgery: Systematic Review and Meta-analysis
(Elsevier, 2018-02-01)Context Pharmacological thromboprophylaxis involves a trade-off between a reduction in venous thromboembolism (VTE) and increased bleeding. No guidance specific for procedure and patient factors exists in urology. Objective ... -
