P2TA: Privacy-preserving task allocation for edge computing enhanced mobile crowdsensing
(Elsevier, 2019-08)In conventional mobile crowdsensing (MCS) applications, the crowdsensing server (CS-server) needs mobile users’ precise locations for optimal task allocation, which raises privacy concerns. This paper proposes a ... -
Paleozoic evolution of western Marie Byrd Land, Antarctica
(Geological Society of America, 2015-09-01)We report geochemical data from (meta-) sedimentary and igneous rocks that crop out in the Ford Ranges of western Marie Byrd Land and discuss the evolution and reworking of the crust in this region during Paleozoic subduction ... -
Palladium Nanoparticles Loaded on Carbon Modified TiO2 Nanobelts for Enhanced Methanol Electrooxidation
(Springer, 2013-09-12)Carbon modified TiO2 nanobelts (TiO2-C) were synthesized using a hydrothermal growth method, as a support material for palladium (Pd) nanoparticles (Pd/TiO2-C) to improve the electrocatalytic performance for methanol ... -
Paradiplomatic policing and relocating Canadian foreign policy
(Sage, 2014-03-12)Even though they claim to recognize that the boundaries between domestic and international security have eroded, scholars of Canadian paradiplomacy have tended to ignore the security-oriented paradiplomatic activities ... -
Parallel Polyadenine Duplex Formation at Low pH Facilitates DNA Conjugation onto Gold Nanoparticles
(American Chemical Society, 2016-11-15)DNA-functionalized gold nanoparticles (AuNPs) have been extensively used in sensing, drug delivery, and materials science. A key step is to attach DNA to AuNPs, forming a stable and functional conjugate. Although the ... -
Parameter estimation of an electrochemistry-based lithium-ion battery model
(Elsevier, 2015-09-30)Parameters for an electrochemistry-based Lithium-ion battery model are estimated using the homotopy optimization approach. A high-fidelity model of the battery is presented based on chemical and electrical phenomena. ... -
Parameter identification in dynamic systems using the homotopy optimization approach
(Springer, 2011-12)Identifying the parameters in a mathematical model governed by a system of ordinary differential equations is considered in this work. It is assumed that only partial state measurement is available from experiments, and ... -
Parameterizing a dynamic influenza model using longitudinal versus age-stratified case notifications yields different predictions of vaccine impacts
(2018-09-06)Dynamic transmission models of influenza are often used in decision-making to identify which vaccination strategies might best reduce influenza-associated health and economic burdens. Our goal was to use laboratory confirmed ... -
Parametric Importance Analysis and Design Optimization of a Torque Converter Model Using Sensitivity Information
(SAE International, 2012-04-16)Torque converters are used as coupling devices in automobile powertrains involving automatic transmissions. Efficient modeling of torque converters capturing various modes of operation is important for powertrain design ... -
Partial oligomerization of pyolysin induced by a disulfide-tethered mutant
(NRC Research Press, 2012-12)The bacterial toxin pyolysin (PLO) belongs to the family of cholesterol-dependent cytolysins (CDCs), which form large, ring-shaped oligomeric pores in cholesterol-containing membranes. Monomeric CDC molecules have a structure ... -
Particle detection on microfluidic chips by differential resistive pulse sensing (RPS) method
(Elsevier, 2018-07-01)The resistive pulse sensing (RPS) method has been widely used for characterization of particles, cells, and biomolecules due to its merits of high sensitivity and resolution. This paper investigates working parameters ... -
Parts-per-Million of Polyethylene Glycol as a Non-Interfering Blocking Agent for Homogeneous Biosensor Development
(American Chemical Society, 2013-11-05)Many homogeneous assays are complicated by the adsorption of probe molecules by the surface of reaction vessels, which are often made of polypropylene or polystyrene-based plastics. To solve this problem, many protein and ... -
Path analysis of warning label effects on negative emotions and quit attempts: A longitudinal study of smokers in Australia, Canada, Mexico, and the US
(Elsevier, 2018-01-01)Background Cigarette pack health warning labels can elicit negative emotions among smokers, yet little is known about how these negative emotions influence behavior change. Objective Guided by psychological theories ... -
A path integral ground state replica trick approach for the computation of entanglement entropy of dipolar linear rotors
(AIP Publishing, 2020-05-14)We calculate the second Rényi entanglement entropy for systems of interacting linear rotors in their ground state as a measure of entanglement for continuous rotational degrees of freedom. The entropy is defined in relation ... -
A path integral methodology for obtaining thermodynamic properties of nonadiabatic systems using Gaussian mixture distributions
(American Institute of Physics, 2018-05)We introduce a new path integral Monte Carlo method for investigating nonadiabatic systems in thermal equilibrium and demonstrate an approach to reducing stochastic error. We derive a general path integral expression for ... -
Pathways and Processes: Reviewing the Role of Young Adults in Urban Structure
(Taylor and Francis, 2017-03-31)Challenges arising from changing demographics, expensive housing, and precarious labor have prompted recent interest in the residential geographies of young adults. Yet, despite attention to young adults' diverse housing ... -
Patterns of Search Result Examination: Query to First Action.
(ACM, 2019-11-03)To determine key factors that affect a user's behavior with search results, we conducted a controlled eye-tracking study of users completing search tasks using both desktop and mobile devices. We focus our investigation ... -
Penalized Regression for Interval-Censored Times of Disease Progression: Selection of HLA Markers in Psoriatic Arthritis
(Wiley, 2015-09)Times of disease progression are interval-censored when progression status is only known at a series of assessment times. This situation arises routinely in clinical trials and cohort studies when events of interest are ... -
