Predicting the phases of a two-dimensional hard-rod system with real-space self-consistent field theory
(APS publishing, 2006-10-16)Polymer self-consistent field theory numerical tools are applied to a two-dimensional hard-rod colloidal system. Rods are represented through an interaction site model density functional theory that is derived and expressed ... -
Prediction of ply crack evolution and stiffness degradation in multidirectional symmetric laminates under multiaxial stress states
(Elsevier, 2018-01-15)A comprehensive study was performed to assess the influence of microscopic ply crack interactions on crack surface opening (COD) and sliding displacements (CSD) for arbitrary plies in general symmetric multidirectional ... -
Predictive models and detection methods applicable in water detection framework for industrial electric arc furnaces
(Elsevier, 2019-09-02)This paper introduces the development of empirical predictive models and detection methods that are incorporated into a water detection framework for an industrial steelmaking electric arc furnace (EAF). The predictive ... -
Predictive Simulation of Reaching Moving Targets Using Nonlinear Model Predictive Control
(Frontiers Media, 2017-01-13)This article investigates the application of optimal feedback control to trajectory planning in voluntary human arm movements. A nonlinear model predictive controller (NMPC) with a finite prediction horizon was used as the ... -
A preference-based, multi-unit auction for pricing and capacity allocation
(Elsevier, 2018-03-01)We study a pricing and allocation problem of a seller of multiple units of a homogeneous item, and present a semi-market mechanism in the form of an iterative ascending-bid auction. The auction elicits buyers' preferences ... -
Preferential recharge in a reclaimed tailings sand upland: Implications on solute flushing
(Elsevier, 2021-12)Study region: A peatland watershed was constructed on a post-mined oil sands lease in Northern Alberta, Canada, with the intention of replicating the function of natural wetlands removed by surface mining. Study focus: ... -
Pregnancy intention and gestational age at first antenatal care (ANC) visit in Rwanda
(Elsevier, 2019-01-01)Background With antenatal care (ANC) coverage now widely seen as a success story in Sub-Sahara Africa (SSA), attention has begun to shift towards exploring the full life-saving potential that ANC holds. Objectives This ... -
Prenatal exposure to recreational drugs affects global motion perception in preschool children
(Springer Nature, 2015-11-19)Prenatal exposure to recreational drugs impairs motor and cognitive development; however it is currently unknown whether visual brain areas are affected. To address this question, we investigated the effect of prenatal ... -
Preparative isolation, fractionation and chemical characterization of dissolved organics from natural and industrially derived bitumen-influenced groundwaters from the Athabasca River watershed
(Elsevier, 2021-07-10)Recent analytical advances have provided evidence that groundwater affected by oil sands process-affected water (OSPW) is reaching the Athabasca River at one location. To understand and discriminate the toxicological risks ... -
Preparing Catalogers for RDA Training
(Taylor & Francis, 2009-09)This article prepares catalogers for the new cataloging standard Resource Description and Access (RDA) by giving trainers and Library and Information Science (LIS) educators the information they need to plan training for ... -
Preschool children's vision screening in New Zealand: a retrospective evaluation of referral accuracy
(BMJ Publishing Group, 2015-11-27)Objectives To assess the accuracy of preschool vision screening in a large, ethnically diverse, urban population in South Auckland, New Zealand. Design Retrospective longitudinal study. Methods B4 School Check vision ... -
Preserving Geometry and Topology for Fluid Flows with Thin Obstacles and Narrow Gaps
(Association for Computing Machinery, 2016-07-01)Fluid animation methods based on Eulerian grids have long struggled to resolve flows involving narrow gaps and thin solid features. Past approaches have artificially inflated or voxelized boundaries, although this sacrifices ... -
Prevalence and Determinants of Poor Food Intake of Residents Living in Long-Term Care
(Elsevier, 2017-06-28)Poor food intake is known to lead to malnutrition in long-term care homes (LTCH), yet multilevel determinants of food intake are not fully understood, hampering development of interventions that can maintain the nutritional ... -
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 ... -
