Stochastic Galerkin methods for the steady-state Navier-Stokes equations
(Elsevier, 2016-04-14)We study the steady-state Navier-Stokes equations in the context of stochastic finite element discretizations. Specifically, we assume that the viscosity is a random field given in the form of a generalized polynomial chaos ... -
A Low-Rank Solver for the Navier--Stokes Equations with Uncertain Viscosity
(Society for Industrial and Applied Mathematics, 2019-10-31)We study an iterative low-rank approximation method for the solution of the steady-state stochastic Navier--Stokes equations with uncertain viscosity. The method is based on linearization schemes using Picard and Newton ... -
The McGovern-Dole food for education and Child nutrition program (MGD): A comparative analysis of reading comprehension gains in Central America
(Elsevier, 2021-01-20)The McGovern-Dole Food for Education and Child Nutrition Program (MGD), funded by the US Department of Agriculture (USDA), is one of the most prominent school feeding programs implemented globally. MGD’s primary objective ... -
Clocking in: Employment outcomes for unaccompanied refugee minors leaving foster care in the United States
(Elsevier, 2021-04-29)Millions of people around the world experience forced displacement from their homes because of war, natural disaster, and political turmoil. A particularly vulnerable sub-group of this population includes children and youth ... -
Paths to Self-Sufficiency for Youth Served Through the Unaccompanied Refugee Minor Foster Care Program in the United States
(Springer Nature, 2021-09-25)Self-sufficiency is a concept commonly used to explore well-being and success of adult refugees. Yet, this concept has not been widely applied to the integration of young adult refugees and immigrants who arrive to the ... -
An Adaptive PID Autotuner for Multicopters with Experimental Results
(2021-09-27)This paper develops an adaptive PID autotuner for multicopters, and presents simulation and experimental results. The autotuner consists of adaptive digital control laws based on retrospective cost adaptive control implemented ... -
Simulations of radio-wave anisotropic scattering to interpret type III radio bursts measurements by Solar Orbiter, Parker Solar Probe, STEREO and Wind
(EDP Sciences, 2021-09-29)We use multi-spacecraft observations of invididual type III radio bursts in order to calculate the directivity of the radio emission, to be compared to the results of ray-tracing simulations of the radio-wave propagation ... -
Enhanced copper-resistance gene repertoire in Alteromonas macleodii strains isolated from copper-treated marine coatings
(PLOS, 2021-09-28)Copper is prevalent in coastal ecosystems due to its use as an algaecide and as an anti-fouling agent on ship hulls. Alteromonas spp. have previously been shown to be some of the early colonizers of copper-based anti-fouling ... -
Competitive X-ray and Optical Cooling in the Collisionless Shocks of WR 140
(2021-09-20)WR 140 is a long-period, highly eccentric Wolf-Rayet star binary system with exceptionally well-determined orbital and stellar parameters. Bright, variable X-ray emission is generated in shocks produced by the collision ... -
Identifying Chemical Aerosol Signatures using Optical Suborbital Observations: How much can optical properties tell us about aerosol composition?
(Copernicus Publications, 2021-09-24)Improvements in air quality and Earth’s climate predictions require improvements of the aerosol speciation in chemical transport models, using observational constraints. Aerosol speciation (e.g., organic aerosols, black ... -
Chinese American adolescents’ experiences of COVID-19 racial discrimination: Risk and protective factors for internalizing difficulties
(American Psychological Association, 2021-08-26)Objective: The coronavirus disease 2019 (COVID-19) pandemic has fueled anti-Asian racism and xenophobia in the United States, which negatively impact Asian Americans’ adjustment. To identify risk and protective factors for ... -
Longitudinal relations among child temperament, parenting, and acculturation in predicting Korean American children’s externalizing problems
(American Psychological Association, 2021)Objective: This study examined the transactional associations among maternal warmth, child temperamental inhibitory control, child externalizing behaviors, and maternal American acculturation in Korean immigrant families ... -
Single-Molecule Measurements Spatially Probe States Involved in Electron Transfer from CdSe/CdS Core/Shell Nanorods
(ACS Publications, 2021-09-16)Semiconductor nanorods with charge-accepting molecules adsorbed on their surfaces serve as model systems for solar energy conversion. An electron photoexcited from the valence band of the nanorod to a high-energy state in ... -
Social Capital, Institutional Rules, and Constitutional Amendment Rates
(2021-09-20)Why are some constitutions amended more frequently than others? Despite the importance of this question to political science and legal theory, there is little consensus regarding the forces that shape constitutional ... -
Modeling the Economic Effects of Increased Drop-out Rates from High School
(Centre of Policy Studies, 2021-09-02)With Covid, high-school students are having difficulty staying in school. We present a dynamic model of the effects of increased drop-out rates. The model accounts for labor productivity, crime costs and high-school ... -
Discriminative and Generative Transformer-based Models For Situation Entity Classification
(2021-09-15)We re-examine the situation entity (SE) classification task with varying amounts of available training data. We exploit a Transformer-based variational autoencoder to encode sentences into a lower dimensional latent space, ... -
Monte Carlo simulations of neutrino and charged lepton propagation in the Earth with nuPyProp
(Proceedings of Science, 2021-07-31)An accurate modeling of neutrino flux attenuation and the distribution of leptons they produce in transit through the Earth is an essential component to determine neutrino flux sensitivities of underground, sub-orbital and ... -
Solar Orbiter/RPW antenna calibration in the radio domain and its application to type III burst observations
(EDP Sciences, 2021-09-16)In order to allow for a comparison with the measurements from other antenna systems, the voltage power spectral density measured by the Radio and Plasma waves receiver (RPW) on board Solar Orbiter needs to be converted ... -
Exosphere Modeling of Proxima b: A Case Study of Photochemical Escape with a Venus-like Atmosphere
(IOP Publishing, 2021-09-14)Exoplanets orbiting M-dwarfs within habitable zones are exposed to stellar environments more extreme than that terrestrial planets experience in our Solar System, which can significantly impact the atmospheres of the ...
