The results of a thermochemical study of the standard molar enthalpy of combustion of 2-adamantanone in the crystalline phase state by isoperibol combustion calorimetry are presented. Two different approaches of combustion-calorimetry data processing (one

Data Guardians: Behaviors and Challenges While Caring for Others' Personal Data

July 23, 2023
Author(s)
Julie Haney, Sandra Prettyman, Mary Frances Theofanos, Susanne M. Furman
Many professional domains require the collection and use of personal data. Protecting systems and data is a major concern in these settings, necessitating that workers who handle personal data under- stand and practice good security and privacy habits

Smart Home Device Loss of Support: Consumer Perspectives and Preferences

July 23, 2023
Author(s)
Julie Haney, Susanne M. Furman
Unsupported smart home devices can pose serious safety and security issues for consumers. However, unpatched and vulnerable devices may remain connected because consumers may not be alerted that their devices are no longer supported or do not understand

Compressed gate characterization for quantum devices with time-correlated noise

July 22, 2023
Author(s)
Michael Gullans, Miguel Caranti, Adam Mills, Jason Petta
As quantum devices make steady progress towards intermediate scale and fault-tolerant quantum computing, it is essential to develop rigorous and efficient measurement protocols that account for known sources of noise in each architecture. Most existing

Michael F. Link, Andrew Shore, Behrang Hamadani, Dustin Poppendieck
Recent interest in commercial devices containing germicidal ultraviolet lamps with a peak emission wavelength at 222 nm (GUV222) has focused on mitigating virus transmission indoors while posing minimum risk to human tissue. However, 222 nm light can

PGAA measurement of chloride diffusion profiles in concrete cylinders

July 21, 2023
Author(s)
Heather H. Chen-Mayer, Neal Berke, Richard Livingston
Chloride diffusion is correlated with corrosion of steel reinforcement in concrete structures. The current standard method for estimating chloride diffusion profile is by destructive chemical analysis. This work investigates the feasibility of Prompt Gamma
