Uncertainties in Swift hardening law parameters and their influence on the flow stress and the hole expansion behavior of dual phase (DP600) steel specimens

January 4, 2023
Author(s)
Dilip K. Banerjee, Kali Prasad, Deepak Kumar, Krishnaswamy Hariharan
Swift hardening law is one of the most widely used phenomenological models to describe flow stress-strain behavior in sheet metal forming simulations. In the present study, a statistical approach was used to investigate the effect of material property

Towards a consensus on a continuous Coordinated Universal Time

November 25, 2022
Author(s)
Judah Levine, Patrizia Tavella, Martin Milton
This paper discusses the considerations that were important in 1972, when the current leap second system was adopted, to maintain UTC, the international reference time scale, closely connected to UT1 – a time scale based on the rotation of the Earth

Portable polarization-entangled photon source & receiver toolset for quantum network metrology

October 4, 2022
Author(s)
Anouar Rahmouni, Thomas Gerrits, Paulina Kuo, Dileep Reddy, Lijun Ma, Xiao Tang, Oliver T. Slattery
A quantum network will consist of many physically separated nodes connected by quantum communication channels that distribute entanglement between them. Such nodes will require mechanisms for the generation, routing, and measurement of quantum states to

On the Effect of Projection on Rank Attacks in Multivariate Cryptography

May 19, 2021
Author(s)
Morten Oygarden, Daniel Smith-Tone, Javier Verbel
The multivariate scheme HFEv- used to be considered a promising candidate for a post-quantum signature system. First suggested in the early 2000s, a version of the scheme made it to the third round of the ongoing NIST post-quantum standardization process

Algorithms and Data Structures for New Models of Computation

February 1, 2021
Author(s)
Paul Black, David W. Flater, Irena Bojanova
In the early days of computer science, the community settled on a simple standard model of computing and a basic canon of general purpose algorithms and data structures suited to that model. With isochronous computing, heterogeneous multiprocessors, flash

Coherent Optical Clock Down-Conversion for Microwave Frequencies with 10-18 Instability

May 22, 2020
Author(s)
Takuma Nakamura, Josue Davila-Rodriguez, Holly Leopardi, Jeffrey Sherman, Tara Fortier, Xiaojun Xie, Joe C. Campbell, Will McGrew, Xiaogang Zhang, Youssef Hassan, Daniele Nicolodi, Kyle Beloy, Andrew Ludlow, Scott Diddams, Franklyn Quinlan
Optical atomic clocks are poised to redefine the SI second, thanks to stability and accuracy more than one hundred times better than the current microwave atomic clock standard. However, the best optical clocks have not seen their performance transferred
