Multiverse: Quantum Optical Network Management

March 19, 2023
Author(s)
Abdella Battou
This paper presents the software-defined management system of DC-QNet, a quantum network testbed deployed across multiple distant sites. The system uses a network management system (NMS) to manage the optical network, the classical IP network, and the

Parallel MPI image reconstructions in GPU using CUDA

March 19, 2023
Author(s)
Klaus Natorf Quelhas, Mark-Alexander Henn, Ricardo Farias, Weston L. Tew, Solomon I. Woods
This work shows that it is possible to obtain faster MPI image reconstructions by implementing the algorithms in parallel in Graphics Processing Units (GPUs) using NVIDIA's CUDA (Compute Unified Device Architecture). While the parallel Kaczmarz's algorithm

Determination of electron beam energy in measuring the electron-impact ionization cross section of He-like Fe24+

March 17, 2023
Author(s)
Yuri Ralchenko, Galen O'Neil, Paul Szypryt, Joseph N. Tan, Aung S. Naing, Yang Yang, Dipti Dipti, Amy Gall, Adam Hosier, David Schultz, Randall Smith, Nancy Brickhouse, Endre Takacs
In an effort to measure electron-impact ionization (EII) cross sections of He-like $Fe^24+}$ at the electron beam ion trap (EBIT) facility of the National Institute of Standards and Technology (NIST), we have experimentally determined the corrections to

Real-Time Flashover Prediction Model for Multi-Compartment Building Structures Using Attention Based Recurrent Neural Networks

March 17, 2023
Author(s)
Wai Cheong Tam, Eugene Yujun Fu, Jiajia Li, Richard D. Peacock, Paul A. Reneke, Thomas Cleary, Grace Ngai, Hong Va Leong, Michael Xuelin Huang
This paper presents the development of an attention based bi-directional gated recurrent unit model, P-Flashv2, for the prediction of potential occurrence of flashover in a traditional 111 m2 single story ranch-style family home. Synthetic temperature data

Controlling solute trapping and solute drag in a phase-field model

March 16, 2023
Author(s)
Arnab Mukherjee, James A. Warren
The finite solid-liquid interface width in phase-field models results in non-equilibrium effects, including solute trapping. Prior phase field modeling has shown that this extra degree of freedom, when compared to sharp-interface models, results in solute

Synergistic Fire Resistance of Nanobrick-wall Coated 3D Printed Photopolymer Lattices

March 16, 2023
Author(s)
Thomas Kolibaba, Callie Higgins, Zack Buck, Dash Weeks, Jason Killgore
Photopolymer additive manufacturing has become the subject of widespread interest in recent years due to its capacity to enable fabrication of difficult geometries that are impossible to build with traditional modes of manufacturing. The flammability of

Users Are Not Stupid: Six Cyber Security Pitfalls Overturned

March 16, 2023
Author(s)
Julie Haney
The skilled and dedicated professionals who strive to improve cyber security may unwittingly fall victim to misconceptions and pitfalls that hold customers and users back from reaching their full potential of being active partners in security. These

Beating thermal noise in a dynamic signal measurement by a nanofabricated cavity-optomechanical sensor

March 15, 2023
Author(s)
Mingkang Wang, Diego Perez Morelo, Georg Ramer, Georges Pavlidis, Jeffrey Schwartz, Liya Yu, Robert Ilic, Andrea Centrone, Vladimir Aksyuk
Thermal fluctuations often impose both fundamental and practical measurement limits on high-performance sensors, motivating the development of techniques that bypass the limitations imposed by thermal noise outside cryogenic environments. Here, we

Modelling Study of Interactions of Ozone and Hydrogen Peroxide on Indoor Surfaces

March 15, 2023
Author(s)
Dustin Poppendieck, Toby J. Carter, David Shaw, Nicola Carslaw
In recent decades, the role of the indoor microenvironment in our exposure to air pollutants has become clearer. Indoor air pollutants are emitted from common household items, including building materials and furnishings, and can then undergo chemical
