Analysis of Propagation of Regular, Extended, and Large BGP Communities

June 20, 2025
Author(s)
Lilia Hannachi, Kotikalapudi Sriram, Douglas Montgomery
This study focuses on the analysis of propagation of Regular, Extended, and Large Communities in the Border Gateway Protocol (BGP). Once added, these communities are often intended to be transitive by default, meaning that they should be propagated from

Experimental Evaluation of AI-Driven Protein Design Risks Using Safe Biological Proxies

June 20, 2025
Author(s)
Svetlana Ikonomova, Bruce Wittmann, Fernanda Piorino Macruz de Oliveira, David Ross, Samuel Schaffter, Olga Vasilyeva, Elizabeth Strychalski, Eric Horvitz, James Diggans, Sheng Lin-Gibson, Geoffrey Taghon
Advances in machine learning are providing new abilities for engineering biology, promising leaps forward with beneficial applications. At the same time, these advances raise concerns about biosecurity. Recently, Wittmann et al. described an in silico

Eave and Vent Experiments (EaVE) Phase A

June 18, 2025
Author(s)
Christopher Brown, Alexander Maranghides, Giovanni Di Cristina Torres, Diana Bailey, Lucy Fox, Eric Link, Selvarajah Ramesh, Monica Flores, Shonali Nazare, J. Houston Miller, Erin McCaughey
This report documents a series of full-scale fire experiments conducted at the National Institute of Standards and Technology (NIST) to characterize the performance of select wildland-urban interface (WUI) eave vents exposed to fire from noncombustible

Demonstration of dispersion gas barometry

June 17, 2025
Author(s)
Yuanchao Yang, Jack Stone, Patrick Egan
Realization of the optical pascal has been limited by systematic errors caused by distortion of the optic. In this work, distortion error is circumvented via synchronous measurement of helium refractivity at two optical frequencies. The resultant pressure

Microscopic-scale defect analysis on b-Ga2O3 through microscopy

June 12, 2025
Author(s)
Minyeong Kim, Andrew Winchester, Alline Myers, Edwin Heilweil, Ory Maimon, Wei-Chang Yang, Sang-Mo Koo, Qiliang Li, Sujitra Pookpanratana
β-Ga2O3 is a wide bandgap semiconductor with potential for surpassing current-generation high-power device performance and cost-effectiveness, due to its unique properties and availability of large high-quality substrates. However, β-Ga2O3 power

Solution Conformation Differences between Conventional and CENP-A Nucleosomes are Accentuated by Reversible Deformation under High Pressure

June 12, 2025
Author(s)
Kushol Gupta, Nikolina Sekulic, Praveen Allu, Nicholas Sapp, Qingqiu Huang, Kathryn Sarachan, Mikkel Christensen, Reidar Lund, Susan N. Krueger, Joseph E. Curtis, Richard Gillilan, Gregory Van Duyne, Ben Black
Solution-based interrogation of the physical nature of nucleosomes has its roots in X-ray and neutron scattering experiments, including those that provided the initial observation that DNA wraps around core histones. In this study, we performed a

Description of the electronic structure of oxyhemoglobin using Fe L-edge X-ray absorption spectroscopy

June 11, 2025
Author(s)
Augustin Braun, Charles Titus, Michael Baker, Max Waters, James Yan, Sang-Jun Lee, Dennis Nordlund, William Doriese, Galen O'Neil, Daniel Schmidt, Daniel Swetz, Joel Ullom, Kent Irwin, Edward Solomon
The electronic structure of oxyhemoglobin (oxyHb), the O2-bound form of the oxygen carrier, has been controversial since the discovery of its diamagnetism in 1936. This study uses partial fluorescence yield Fe L-edge X-ray absorption spectroscopy (XAS) in

Radial polarization imaging of entangled biphoton state

June 11, 2025
Author(s)
Jiung Kim, Jeeseong Hwang, Martin Sohn
Polarization entanglement of single photons is a key element to enable quantum 2.0 applications such as quantum computing, quantum networks, and quantum sensing. Verification and fidelity assessment of quantum entanglement of single photon pairs correlated

A zero trust architecture (ZTA) enables secure authorized access to enterprise resources that are distributed across on-premises and multiple cloud environments, while enabling a hybrid workforce and partners to access resources from anywhere, at any time

Ionization Constant of Water

June 10, 2025
Author(s)
Hugues Arcis, Allan Harvey
This is an update of two tables in the CRC Handbook of Chemistry and Physics (for the 106th ed.) to reflect a new standard formulation adopted in 2024 by the International Association for the Properties of Water and Steam (IAPWS).

Partition Functions and Ideal-Gas Thermodynamics for Carbon Dioxide

June 10, 2025
Author(s)
Sergey Tashkun, Allan Harvey
We have constructed an effective Hamiltonian model for the rotational-vibrational states of molecular carbon dioxide. The model is constrained by a large amount of spectroscopic data for frequencies of rovibrational transitions. From this formulation, we

Residual stress-assisted static globularization in electron beam powder bed fusion Ti-6Al-4V from powder recovery and hot isostatic pressing
