Inhibition by Tetrahydroquinoline Sulfonamide Derivatives of the Activity of Human 8-Oxoguanine DNA Glycosylase (OGG1) for Several Products of Oxidatively-induced DNA Base Lesions

December 17, 2021
Author(s)
Miral M. Dizdar, Melis Kant, Pawel Jaruga, Erdem Coskun, Yu-Ki Tahara, R. S. Lloyd, Eric T. Kool
DNA glycosylases involved in the first step of the base excision repair pathway of DNA repair are promising targets in cancer therapy. There is evidence that reduction of their activities may enhance cell killing in malignant tumors. Recently, two

Quantitative Evaluation of Footwear Evidence: Initial Workflow for an End-to-End System

November 23, 2021
Author(s)
Gautham Venkatasubramanian, Vighnesh Hegde, Steven Lund, Hariharan K. Iyer, Martin Herman
In the U.S., footwear examiners make decisions about the sources of crime scene shoe impressions using subjective criteria. This has raised questions about the accuracy, repeatability, reproducibility, and scientific validity of footwear examinations

The MaCFP Condensed Phase Working Group: A Structured, Global Effort Towards Pyrolysis Model Development

November 23, 2021
Author(s)
Isaac Leventon, Benjamin Batiot, Morgan Bruns, Simo Hostikka, Yuji Nakamura, Pedro Reszka, Thomas Rogaume, Stanislav Stoliarov
The International Association for Fire Safety Science (IAFSS) Working Group on Measurement and Computation of Fire Phenomena (i.e., the MaCFP Working Group) has been established as a global collaborative effort between experimentalists and modelers in the

Client-side XSLT, Validation and Data Security

November 22, 2021
Author(s)
Wendell Piez
Client-side XSLT (CSX) is often used in scenarios where data (in XML) from a remote server is provided to a user who processes it in some way, for example rendering it locally for display. That is, the server provides the data and the client does the work

Enhancement of electromagnetically induced transparency based Rydberg-atom electrometry through population repumping

November 22, 2021
Author(s)
Christopher L. Holloway, Nik Prajapati, Matt Simons, Samuel Berweger, Aly Artusio-Glimpse, Amy Robinson
We demonstrate the improvement of Rydberg electrometry based on electromagnetically induced transparency (EIT) through the use of a ground state repumping laser. Though there are many factors that limit the sensitivity of radio frequency field measurements

Final Report: Quantitative Measures for Footwear Impression Comparisons

November 21, 2021
Author(s)
Martin Herman
This document is the Final Report for the Interagency Agreement between the National Institute of Justice, Office of Justice Programs and the National Institute of Standards and Technology. The goal of this effort has been to research and develop

A Semi-Supervised Approach for Automatic Crystal Structure Classification

November 18, 2021
Author(s)
Satvik Lolla, Haotong Liang, Aaron Kusne, Ichiro Takeuchi, William D. Ratcliff
The structural solution problem can be a daunting and time consuming task. Especially in the presence of impurity phases, current methods such as indexing become more unstable. In this work, we apply the novel approach of semi-supervised learning towards

Using CO2 Monitoring to Manage Ventilation in Buildings

November 18, 2021
Author(s)
Andrew K. Persily
The measurement of indoor carbon dioxide concentrations has been used for many years to assess and control building ventilation rates, as well as to characterize indoor air quality. Over the years these applications of indoor CO2 monitoring have been

Activation of Mechanophores in a Thermoset Matrix by Instrumented Scratch

November 17, 2021
Author(s)
Chelsea S. Davis, Jeremiah Woodcock, Ryan Beams, Mitchell Rencheck, Muzhou Wang, Stephan J. Stranick, Aaron M. Forster, Jeffrey Gilman
Scratches in polymer coatings and barrier layers negatively impact optical properties (haze, light transmission, etc.), initiate routes of degradation or corrosion (moisture permeability), and nucleate delamination of the coating. Detecting scratches in

Input/Output Check Bugs Taxonomy: Injection Errors in Spotlight

November 17, 2021
Author(s)
Irena Bojanova, Carlos Galhardo, Sara Moshtari
In this work, we present an orthogonal classification of input/output check bugs, allowing precise structured descriptions of related software vulnerabilities. We utilize the Bugs Framework (BF) approach to define two language-independent classes that

Modeling of Combustion of Fluorine-Containing Refrigerants

November 17, 2021
Author(s)
Valeri I. Babushok, Donald R. Burgess Jr., Dennis Kim, Michael Hegetschweiler, Gregory T. Linteris
A gas-phase chemical kinetic model for the combustion of C1-C3 fluorine-containing refrigerants is presented, including a list of relevant species, their thermodynamic and transport properties, and the Arrhenius parameters for their reactions. Also

Evaluation of a Modified Void Descriptor Function to Uniquely Characterize Pore Networks and Predict Fracture Location in Additively Manufactured Metals

November 15, 2021
Author(s)
Dillon Watring, Jake Benzing, Orion Kafka, Li-Anne Liew, Newell Moser, John Erickson, Nik Hrabe, Ashley Spear
Variations in additive manufacturing (AM) processing parameters can lead to variations in porosity, making it challenging to predict pore- or void-sensitive mechanical response in AM metals. A recently developed pore metric, the void descriptor function

Atom probe tomography for isotopic analysis: development of the 34S/32S system in sulfides

November 12, 2021
Author(s)
Phillip Gopon, James Douglas, Frederick Meisenkothen, Jaspreet Singh, Andrew London, Michael Moody
Using a combination of simulated data and pyrite isotopic reference materials, we have refined a methodology to obtain quantitative δ34S measurements from atom probe tomography (APT) datasets. This study builds on previous attempts to characterize relative
