Introduction: The Metabolomics Quality Assurance and Quality Control Consortium (mQACC) organized a workshop during the Metabolomics 2022 conference. Objectives: The goal of the workshop was to disseminate recent findings from mQACC community-engagement

Bug, Fault, Error, Weakness, or Vulnerability - Poster

November 7, 2023
Author(s)
Irena Bojanova
Motivation: Software security vulnerabilities are leveraged to attack cyberspace and critical infrastructure, leading to security failures. When communicating about them, however, even security experts might conflate essential related software concepts

Bugs Framework (BF) - Poster

November 7, 2023
Author(s)
Irena Bojanova
Motivation: Crucial need of a formal classification system allowing unambiguous specification of software security bugs and weaknesses, and the vulnerabilities that exploit them. Objective: Create bug models, weakness taxonomies, and vulnerability models

Improving Fitting CAD to 3D Point Cloud Acquired with Line-of-Sight Sensor

November 7, 2023
Author(s)
Marek Franaszek, Prem Rachakonda, Kamel S. Saidi
Due to self-occlusions in 3D point clouds acquired with line-of-sight sensors, an incomplete representation of an object's surface is used in fitting a CAD (computer-aided design) model to the data. For certain types of object geometry, CAD pose fitted

Labeling Software Security Vulnerabilities - Poster

November 7, 2023
Author(s)
Irena Bojanova, John Guerrerio
Motivation: Crucial need for systematic comprehensive labeling of the more than 228 000 publicly disclosed cybersecurity CVE vulnerabilities to enable advances in modern AI cybersecurity research. Objective: Utilize the Bugs Framework (BF) formalism for BF

The Magnetic Suspension Balance - 40 Years of Advancing Densimetry and Sorption Science Xiaoxian Yang1, Reiner Kleinrahm2, Mark O. McLinden3, Markus Richter1,

Xiaoxian Yang, Reiner Kleinrahm, Mark O. McLinden, Markus Richter
This paper reviews the 40-year evolution and application of the magnetic-suspension balance (MSB) and discusses some challenging issues of the technique. A MSB, as we define it here, is a magnetic-suspension coupling (MSC) connected with an analytical

Tracking Active Phase Behavior on Boron Nitride during the Oxidative Dehydrogenation of Propane Using Operando X-Ray Raman Spectroscopy

November 6, 2023
Author(s)
Melissa Cendejas, Oscar Paredes Mellone, Unni Kurumbail, Zisheng Zhang, Jacob Jansen, Faysal Ibrahim, Son Dong, John Vinson, Anastassia Alexandrova, Dimosthenis Sokaras, Simon Bare, Ive Hermans
Hexagonal boron nitride (hBN) is a highly selective catalyst for the oxidative dehydrogenation of propane (ODHP) to propylene. Using a variety of ex situ characterization techniques, the activity of the catalyst has been attributed to the formation of an

ASTRA: a Transition-Density-Matrix Approach to Molecular Ionization

November 3, 2023
Author(s)
Luca Argenti, Juan Martin Randazzo, carlos maranthe, Jeppe Olsen, Siddhartha Chattopadhyay, Barry I. Schneider
We describe ASTRA (AttoSecond TRAnsitions), a new close-coupling approach to molecular ionization that uses many-body transition density matrices between ionic states with arbitrary spin and symmetry, in combination with hybrid integrals between Gaussian

Digital Twin Core Conceptual Models and Services

November 3, 2023
Author(s)
Shi-Wan Lin, Kym Watson, Guodong Shao, Ljiljana Stojanovic, Bassam Zarkout
To improve operational efficiency and enhance competitiveness in business, organizations are broadly undergoing digital transformation. As a foundation for digital transformation, digital twins enable system operators to dynamically represent, diagnose

Linkage Transformations in a Three-Dimensional Covalent Organic Framework for High-Capacity Adsorption of Perfluoroalkyl Substances

November 3, 2023
Author(s)
Andrea Zeppuhar, Devin Rollins, Dale L. Huber, Emmanuel Bazan-Bergamino, Fu Chen, Hayden Evans, Mercedes Taylor
Despite their many advantages, covalent organic frameworks (COFs) built from three-dimensional monomers are synthetically difficult to functionalize. Herein, we provide a new synthetic approach to the functionalization of a three-dimensional covalent

Long Range and Collective Impact of Au Surface Adatoms on Nanofin Growth

November 3, 2023
Author(s)
Babak Nikoobakht, Aaron Johnston-Peck, Jerry Tersoff
In the Au-catalyzed vapor-liquid-solid (VLS) growth of semiconductor nanowires, individual Au nanodroplets can result in single nanowires per site. However, growth of single nanofins per site using the same process becomes unpredictable. Our results show

Partial Elastic Shape Registration of 3D Surfaces using Dynamic Programming

November 3, 2023
Author(s)
Javier Bernal, James F. Lawrence
The computation of the elastic shape registration of two simple surfaces in 3−dimensional space and therefore of the elastic shape distance between them has been investigated by Kurtek, Jermyn, et al. who have proposed algorithms to carry out this

Annual Report on the U.S. Manufacturing Economy: 2023

Author(s)
Douglas Thomas
This report provides a statistical review of the U.S. manufacturing industry. There are three aspects of U.S. manufacturing that are considered: (1) how the U.S. industry compares to other countries, (2) the trends in the domestic industry, and (3) the

Recommendations for setting a criterion and assessing commutability of sample materials used in external quality assessment/proficiency testing schemes

November 2, 2023
Author(s)
Sverre Sandberg, Pernille Fauskanger, Jesper Johansen, Thomas Keller, Jeffrey Budd, Neil Greenberg, robert rej, MAURO PANTEGHINI, VINCENT DELATOUR, Ferruccio Ceriotti, Liesbet Deprez, Johanna Camara, Finlay MacKenzie, Alicia Lyle, Eline van der Hagen, Chris Burns, W. Greg Miller
It is important for external quality assessment materials (EQAMs) to be commutable with clinical samples; i.e., they should behave like clinical samples when measured using end-user clinical laboratory in vitro diagnostic medical devices (IVD-MDs). Using

Watching (De)Intercalation of 2D Metals in Epitaxial Graphene: Insight into the Role of Defects

The de-intercalation processes of 2D Ag and 2D Ga from the graphene-SiC interface was tracked using full-field photoemission electron microscopy. The intercalation "windows" are observed in both systems and follow very different dynamics. The de- and re

Dietary Supplement Laboratory Quality Assurance Program: Exercise 1 Final Report
