Using Business Impact Analysis to Inform Risk Prioritization and Response

February 26, 2025
Author(s)
Stephen Quinn, Nahla Ivy, Julie Anne Chua, Matthew Barrett, Larry Feldman, Daniel Topper, Greg Witte, Robert Gardner
While business impact analysis (BIA) has historically been used to determine availability requirements for business continuity, the process can be extended to provide a broad understanding of the potential impacts of any type of loss on the enterprise

A Security Perspective on the Web3 Paradigm

February 25, 2025
Author(s)
Dylan Yaga, Peter Mell
Web3 is a proposed vision for the future of the internet that is restructured to be more user-centric with an emphasis on decentralized data. Users would own and manage their personal data, and systems would be decentralized and distributed. Digital tokens

Don't Use LLMs to Make Relevance Judgments

February 25, 2025
Author(s)
Ian Soboroff
Making the relevance judgments for a TREC-style test collection can be complex and expensive. A typical TREC track usually involves a team of six contractors working for 2-4 weeks. Those contractors need to be trained and monitored. Software has to be

Kolmogorov turbulence in atomic Bose-Einstein condensates

February 25, 2025
Author(s)
Ian Spielman, Mingshu Zhao, Junheng Tao
We investigated turbulence in atomic Bose-Einstein condensates (BECs) using a minimally destructive, impurity injection technique analogous to particle image velocimetry in conventional fluids. Our approach transfers small regions of the BEC into a

Measurement resolution enhanced coherence for lattice fermions

February 25, 2025
Author(s)
Ian Spielman, Hilary Hurst, Yik Teoh
Weak measurement enables the extraction of targeted information from a quantum system while minimizing decoherence due to measurement backaction. However, in many-body quantum systems backaction can have unexpected effects on wavefunction collapse. We

System Vicarious Calibration for climate and global long-term operational ocean color applications

February 25, 2025

Giuseppe Zibordi, B. Carol Johnson, Ewa Kwiatkowska, Kenneth Voss, David Antoine, Sean William Bailey, Andrew Barnard, Brian Barnes, Agnieszka Bialek, Shuguo Chen, Susanne Craig, Constant Mazeran, FREDERIC MELIN, Jee-Eun Min, Hiroshi Murakami, Menghua Wang
System Vicarious Calibration (SVC) enhances the accuracy of satellite ocean color radiometric data products by removing the bias due to the intrinsic inaccuracies affecting both the responsivity of the space sensor and the correction for the atmospheric

Compressed Liquid (p-r-T) Measurements of trans-1,2-Dichloroethene [R1130(E)]

February 24, 2025
Author(s)
Tara Fortin, Stephanie Outcalt
Pressure-density-temperature (p-ρ-T) data for the refrigerant R-1130(E) (trans-1,2-dichloroethene) were measured in the compressed liquid phase using an automated vibrating tube densimeter. Overall, the measurements covered temperatures from 270 K to 410 K

Chemical heterogeneity observed in the development of photo-oxidized PET micro- and nanoparticle weathered controls

February 19, 2025
Author(s)
John Pettibone, Eric S. Windsor, Tae Joon Cho, Thomas Forbes, Ying Tung Kuo, Justin Gorham, Li Piin Sung, Song-Syun Jhang
Determining unknown secondary micro and nanoplastic (MNP) composition remains a persistent analytical challenge for field collected samples. The availability of material standards should accelerate method development for improved identification. Here

Role of NEIL1 in genome maintenance

February 19, 2025
Author(s)
Amanda McCullough, Irina Minko, Michael Luzadder, Jamie Zuckerman, Pawel Jaruga, Vladimir Vartanian, M Miral Dizdar, R. Stephen Lloyd
Phylogenetic analyses of DNA glycosylases that function in the initiation step of base excision repair reveal a high degree of conservation within the genes encoding Nei-like DNA glycosylase 1 (NEIL1). In concert with other glycosylases, this enzyme is an

State Space Neural Network with Nonlinear Physics for Mechanical System Modeling

February 19, 2025
Author(s)
Reese Eischens, Tao Li, Gregory Vogl, Yi Cai, Yongzhi Qu
Dynamic modeling of mechanical systems is important for the monitoring, diagnostics, control, and prediction of system behaviors. Modeling dynamic system is one of the emerging tasks in scientific machine learning. Neural networks have been used to learn

Vitamin E Acetate Causes Softening of Pulmonary Surfactant Membrane Models
