Dataset for airborne PCBs and OH-PCBs inside and outside urban and rural U.S. schools

Rachel Marek, Peter S Thorne, Nicholas J Herkert, Andrew M Awad & Keri C Hornbuckle
This dataset from the Iowa Superfund Research Program (ISRP) includes indoor and outdoor air mass, concentration, and associated quality control of PCBs and OH-PCBs in two rural schools and four urban schools, the latter near a PCB-contaminated waterway of Lake Michigan in the United States. Samples (n=108) were collected as indoor/outdoor pairs using PUF-PAS from January 2012 to November 2015. Samples were analyzed using GC/MS-MS for all 209 PCBs and 72 OH-PCBs. Concentrations inside schools...

Dataset for a semi-target analytical method for quantification of OH-PCBs in environmental samples

Panithi Saktrakulkla, Ram C. Dhakal, Hans-Joachim Lehmler & Keri C. Hornbuckle
Hydroxylated polychlorinated biphenyls (OH-PCBs) are oxidative metabolites of PCBs and residuals found in original Aroclors. OH-PCBs are known to play a role as genotoxicants, carcinogens, and hormone disruptors, and therefore it is important to quantify their presence in human tissues, organisms, and environmental matrices. Of 837 possible mono-OH-PCBs congeners, there are only ~70 methoxylated PCB (MeO-PCB) standards commercially available. Hence, a semi-target analytical method is needed for unknown OH-PCBs. The mass concentrations of these unknowns...

Maasai Speech Samples

Lindsey Taylor Quinn-Wriedt
This is a collection of audio files from seven native speakers of Maasai, an Eastern Nilotic language spoken in southern Kenya and Northern Tanzania. These files are the raw data that were collected for analysis to write my dissertation, Vowel Harmony in Maasai (2013). The two fieldwork trips to Arusha, Tanzania were funded by a T. Anne Cleary International Dissertation Research Fellowship from the University of Iowa and by Doctoral Dissertation Research Improvement Grant BCS1149310...

Data for A Hybrid Fluxgate and Search Coil Magnetometer Concept Using a Racetrack Core

David M. Miles
The data is raw measurements from a prototype magnetic field instrument. The data was all captured in a laboratory setup and is intended to demonstrate the utility of the instrument concept to future satellite and rocket applications. There are also a series of matlab scripts which import and process the data to create the figures in the accompanying manuscript.

Dataset for “Fully quantum embedding with density functional theory for full configuration interaction quantum Monte Carlo”

Hayley R Petras, Daniel S Graham, Sai Kumar Ramadugu, Jason D Goodpaster & James J Shepherd
Description of methods used for collection/generation of data: - FCIQMC calculations: target population 10 - 10^6 (log steps), timestep range of 9e-7 to 2e-2, real amplitudes were used, initial population = 10, and initiator approximation was used. - Reblocking Analysis: reblock_hande.py was used. Reblocking was started at various iteration numbers, determined by visual inspection of shift vs sum. If optimal reblocking did not occur, the mean value for the projected energy was used from the...
