Hardware Security Failure Scenarios

November 13, 2024
Author(s)
Peter Mell, Irena Bojanova
Historically, hardware has been assumed to be inherently secure. However, chips are both created with software and contain complex encodings (e.g., circuit designs and firmware). This leads to bugs, some of which compromise security. This publication

Naturally occurring background radiation is a potential source of correlated decoherence events in superconducting qubits that will challenge error-correction schemes. In order to characterize the radiation environment in an unshielded laboratory

The NIST Cybersecurity Framework (CSF) 2.0 (Polish translation)

November 12, 2024
Author(s)
Cherilyn Pascoe, Stephen Quinn, Karen Scarfone
The NIST Cybersecurity Framework (CSF) 2.0 provides guidance to industry, government agencies, and other organizations to manage cybersecurity risks. It offers a taxonomy of high-level cybersecurity outcomes that can be used by any organization —

Impacts of Alfalfa Nutrient Concentrate on Pellet Physical Attributes, Growth Performance, Metabolism and Nutritional Quality of Rainbow Trout, Oncorhynchus mykiss

November 8, 2024
Author(s)
Hu Chen, Patrick Blaufuss, Dong-Fang Deng, Fabio Casu, Emma Kraco, Brian Shepherd, Wendy Sealey, Aaron Watson, Matthew Digman, Deborah Samac
This study addresses the escalating demand for aquatic feed by exploring the potential of alfalfa nutrient concentrate (ANC) as feed ingredient for rainbow trout. Test diets contained varying ANC levels (0%, 5%, 10%, 15%, and 20%) to replace fishmeal (32%

Neutrons for the Future

November 8, 2024
Author(s)
Stephen Wilson, Mike Hore, Steven Kline
Producing neutrons in quantities sufficient for most applications is challenging and requires centralized facilities that develop and deploy cutting-edge instrumentation for the Nation's scientific and engineering communities. For over 50 years, the NIST
