Preparation and Standardization of 229Th SRM 4328d

February 24, 2023
Author(s)
Ronald Colle, Lizbeth Laureano-Perez, Morgan DiGiorgio
The certified massic activity for 229Th in SRM 4328d was obtained by 4παβ liquid scintillation (LS) counting by comparative measurements in 2022 against SRM 4328c. Both SRMs were prepared from the identical 2007 229Th stock solution. SRM 4328c was

Control of Micro-and Nanostructure of Layered Double Hydroxides by Hydrothermal Treatment

February 23, 2023
Author(s)
Keiichiro Maegawa, Fan Zhang, Qiaxian Johnson, Mihaela Jitianu, Tan Wai Kian, Go Kawamura, Atsunori Matsuda, Andrei Jitianu
Layered double hydroxides (LDHs) are mixed M(II) and M(III) hydroxides with positively charged lamellar brucite layers and interlayered anions. LDHs attracted significant attention due to their anion and cation-exchange ability, adsorption capacity, and

Empirical Validation of Automated Vulnerability Curation and Characterization

February 23, 2023
Author(s)
Ahmet Okutan, Peter Mell, Medhi Mirakhorli, Igor Khokhlov, Joanna Santos, Danielle Gonzalez, Steven Simmons
Prior research has shown that public vulnerability systems such as US National Vulnerability Database (NVD) rely on a manual, time-consuming, and error-prone process which has led to inconsistencies and delays in releasing final vulnerability results. This

Impact of Code Complexity On Software Analysis

February 23, 2023
Author(s)
Charles D. De Oliveira, Elizabeth Fong, Paul E. Black
The Software Assurance Metrics and Tool Evaluation (SAMATE) team studied thousands of warnings from static analyzers. Tools have difficulty distinguishing between the absence of a weakness and the presence of a weakness that is buried in otherwise

Unified graph neural network force-field for the periodic table: solid state applications

February 23, 2023
Author(s)
Kamal Choudhary, Brian DeCost, Lily Major, Keith Butler, Jeyan Thiyagalingam, Francesca Tavazza
Classical force fields (FFs) based on machine learning (ML) methods show great potential for large scale simulations of solids. MLFFs have hitherto largely been designed and fitted for specific systems and are not usually transferable to chemistries beyond

FixItFelix: improving genomic analysis by fixing reference errors

February 21, 2023
Author(s)
Sairam Behera, Jonathan LeFaive, Peter Orchard, Justin Zook, Fritz Sedlazeck
The current version of the human reference genome, GRCh38, contains a number of errors including 1.2 Mbp of falsely duplicated and 8.04 Mbp of collapsed regions. These errors impact the variant calling of 33 protein-coding genes, including 12 with medical

Solvent Transport Model for Polyamide Nanofilm Membranes Based on Accurate Hansen Solubility Parameters

February 21, 2023
Author(s)
Min Gyu Shin, Wansuk Choi, June Huh, William Mulhearn, Jung Sun Hwang, Christopher Stafford, Jeong F Kim, Jung Hyun Lee
Polyamide (PA) nanofilm membranes for solvent filtration are widely used in various industries. However, reliable models that can describe solvent transport in PA membranes have yet to be developed owing to measurement challenges associated with the highly

Community Resource for Innovation in Polymer Technology (CRIPT): A Scalable Polymer Material Data Structure

February 20, 2023
Author(s)
Dylan Walsh, Weizhong Zou, Ludwig Schneider, Reid Mello, Michael Deagen, Joshua Mysona, Tzyy-Shyang Lin, Juan de Pablo, Klavs Jensen, Debra Audus, Bradley Olsen
Polymeric materials are integral components of nearly every aspect of modern life. However, developing cheminformatic solutions for polymers has been difficult since they are large stochastic molecules with hierarchical structures spanning multiple length

Knowledge representation for hierarchical and interconnected business contexts

February 19, 2023
Author(s)
Nenad Ivezic, Boonserm Kulvatunyou, Hakju Oh, Elena Jelisic, Scott Nieman, Anicic Nenad, Marjanovic Zoran
Although business context has been introduced as an important concept for message standards usage and maintenance, its usability depends on the tech-nique used to represent contextual knowledge. This paper proposes a logic-based business context modeling

Colloquium: Advances in automation of quantum dot devices control

February 17, 2023
Author(s)
Justyna Zwolak, Jacob Taylor
Arrays of quantum dots (QDs) are a promising candidate system to realize scalable, coupled qubit systems and serve as a fundamental building block for quantum computers. In such semiconductor quantum systems, devices now have tens of individual

NIST Metric Recipes

February 17, 2023
Author(s)
Elizabeth Benham, Tanna Nguyen
Cooking and baking using a kitchen scale is a fun way to build metric system abilities and apply measurement techniques. This recipe series is ideal for both new and experienced chefs. Completing a NIST metric recipe is an opportunity to apply culinary

Biglycan regulates bone development and regeneration

February 16, 2023
Author(s)
Reut Shainer, Vardit Kram, Tina Kilts, Andrew Doyle, Inbal Shainer, Carl Simon Jr., Jinyang Zeng-Brouwers, Liliana Schaefer, Marian Young
Endochondral bone development and regeneration relies on activation and proliferation of periosteum derived cells (PDCs). Biglycan (Bgn), an extracellular matrix component, is known to be expressed in bone and cartilage, however little is known about its

Development & Validation of A Rapid GC-MS Method for Seized Drug Screening

February 15, 2023
Author(s)
Madeline Bloom, Edward Sisco, Ira Lurie
Controlled substances are one of the most frequently analyzed types of evidence in forensic laboratories. An increase in frequency of seizures in recent years has necessitated a need for rapid screening techniques to decrease case backlogs and expedite
