Fronesis: Digital Forensics-Based Early Detection of Ongoing Cyber-Attacks

December 30, 2022
Author(s)
Athanasios Dimitriadis, Efstratios Lontzetidis, Boonserm Kulvatunyou, Nenad Ivezic, Dimitris Gritzalis, Ioannis Mavridis
Traditional attack detection approaches utilize predefined databases of known signatures about already-seen tools and malicious activities observed in past cyber-attacks to detect future attacks. More sophisticated approaches apply machine learning to

Mechanism of Bismuth Stimulated Bottom-up Gold Feature Filling

December 30, 2022
Author(s)
Daniel Josell, Trevor Braun, Thomas P. Moffat
The mechanism that underlies 〖Bi〗^(3+)-stimulated extreme bottom-up Au filling of trenches and vias in slightly alkaline 〖Na〗_3 Au(〖SO〗_3 )_2+〖Na〗_2 〖SO〗_3 electrolytes is explored. The remarkable void-free feature filling and self-passivation behavior

Strain and Charge Contributions to the Magnetoelectric Coupling in Fe 3 O 4 /PMN-PT Artificial Multiferroic Heterostructures

December 30, 2022
Author(s)
Patrick Schoffmann, Anirban Sarkar, Mai H. Hamed, Tanvi Bhatnagar-Schoffmann, Sabine Putter, Brian Kirby, Alexander Grutter, Juri Barthel, Emmanuel Kentzinger, Annika Stellhorn, Andrei Gloskovskii, Martina Muller, Thomas Bruckel
The quest to realize new kinds of data storage devices has motivated recent studies in the field of magnetoelectric heterostructures. One of the most commonly investigated systems is Fe 3O 4/PMN-PT, however, the interplay between different coupling

Analysis of Strain Correction Procedures for Single Fiber Tensile Testing

December 29, 2022
Author(s)
Amy Engelbrecht-Wiggans, Amanda L. Forster
Accurate strain measurement for single fibers is critical for many engineering applications. Typically, the crosshead displacement is used to calculate strain when performing mechanical testing, however there are complicating factors: slack in the specimen

Reconstruction of Parent Microstructures in TRIP Titanium Alloys

December 28, 2022
Author(s)
Alec Saville, Ben Ellyson, Jake Benzing, Amy Clarke
The metastable β-Ti titanium alloy Ti-10V-2Fe-3Al (wt%) exhibits transformation induced plasticity (TRIP) (or the transformation of the parent β phase to product martensite) and desirable work hardening characteristics. However, the majority of the parent

Simulation of Residential CO Exposures from Portable Generators with and without CO Hazard Mitigation Systems Meeting Requirements of Voluntary Standards, Revision 1

December 28, 2022
Author(s)
Steven Emmerich, Brian Polidoro, Matthew Hnatov, Janet Buyer, Matthew Brookman
This report documents work performed by the U.S. National Institute of Standards and Technology (NIST) and the U.S. Consumer Product Safety Commission (CPSC or Commission) under an interagency agreement in support of the Commission's effort to address the

2022 Update for the Differences Between Thermodynamic Temperature and ITS 90 Below 335 K

December 27, 2022
Author(s)
Christof Gaiser, Bernd Fellmuth, Roberto Maria Gavioso, Murat Kalemci, Vladimir Kytin, Tohru Nakano, Laurent Pitre, Anatoli Pokhodun, Patrick Rourke, Richard Rusby, Peter P.M. Steur, Weston L. Tew, Robin James Underwood, Rod White, Inseok Yang, Jintao Zhang
In 2011, a working group of the Consultative Committee for Thermometry published best estimates of the differences between thermodynamic temperature (T) and the International Temperature Scale ITS 90 (T90). But for temperatures below 335 K, it was stated

Characterizing light engine uniformity and its influence on LCD-based vat photopolymerization printing

December 27, 2022
Author(s)
Benjamin Caplins, Callie Higgins, Thomas Kolibaba, Uwe Arp, C Cameron Miller, Dianne L. Poster, Clarence Zarobila, Yuqin Zong, Jason Killgore
Vat photopolymerization (VP) is a rapidly growing category of additive manufacturing. As VP methods mature the expectation is that the quality of printed parts will be highly reproducible. At present, detailed characterization of the light engines used in
