Julie Haney, Wayne Lutters, Jody Jacobs
Cybersecurity advocates motivate individuals and organizations to adopt positive security behaviors. Based on our research, we describe qualities of successful advocates. Our findings have practical implications for expanding the cybersecurity workforce by

Scaling the Phish: Advancing the NIST Phish Scale

July 3, 2021
Author(s)
Fernando Barrientos, Jody Jacobs, Shanee Dawkins
Organizations use phishing training exercises to help employees defend against the phishing threats that get through automatic email filters, reducing potential compromise of information security for both the individual and their organization. These

What Futuristic Technology Means for First Responders: Voices from the Field

Shanee Dawkins, Kerrianne Buchanan, Yee-Yin Choong, Kristen K. Greene
The public safety communication technology landscape in the United States (U.S.) is evolving to supplement the use of land mobile radios with the use of a broader spectrum of communication technologies for use on the newly created Nationwide Public Safety

Dissipative preparation of W states in trapped ion systems

July 2, 2021
Author(s)
Daniel Cole, Jenny Wu, Stephen Erickson, Panyu Hou, Andrew C. Wilson, Dietrich Leibfried, Florentin Reiter
We present protocols for dissipative entanglement of three trapped-ion qubits, and we discuss in detail a scheme that uses sympathetic cooling as the dissipation mechanism. This scheme relies on tailored destructive interference to generate one of six

Structural and Thermoelectric Properties of Pb4In2.6Bi3.4Se13

July 2, 2021

Winnie Wong-Ng, J Guo, Yonggao Yan, James A. Kaduk
Quaternary selenide, Pb4In2.6Bi3.4Se13 (x = 2.4 member of the Pb4(InxBi6-xSe13 solid solution), was synthesized by a solid-state technique, and its structure was determined using powder X-ray diffraction (XRD). Pb4In2.6Bi3.4Se13 crystallizes in the

Universal Spectrum Identifier for mass spectra

Author(s)
Maria Dillard, Cath Brooks, Helen Fisher, Hans Pietersen, Alwin Nijhuis, Anita van Breda, Susan Durden
Engagement is an important and necessary part of all planning and decision-making for any infrastructure project. Engagement is included at each step of the natural and nature-based features (NNBF) framework (steps detailed in Chapter 2) because we assume

Coulombically-stabilized oxygen hole polarons enable fully reversible oxygen redox
