Neuromorphic computing with nanoscale spintronic oscillators

July 26, 2017
Author(s)
Jacob Torrejon, Mathieu Riou, Flavio Abreu Araujo, Sumito Tsunegi, Guru Khalsa, Damien Querlioz, Paolo Bortolotti, Vincent Cros, K. Yakushiji, Akio Fukushima, Hitoshi Kubota, Shinji Yuasa, Mark D. Stiles, Julie Grollier
In the brain, hundred billions of neurons develop rhythmic activities and interact to process information. Taking inspiration from this behavior to realize high density, low power neuromorphic computing requires coupling huge numbers of nanoscale non

On Neutron Activation Analysis with Gamma,Gamma Coincidence Spectrometry

July 26, 2017
Author(s)
Rolf L. Zeisler, Hana Cho, Ibere Souza Ribeiro Junior, Martin G. Shetty, Danyal J. Turkoglu
A new  coincidence system has been set up at NIST. It is operated with a digital data finder supported by new software developed at NIST. The system is used to explore possible enhancements in instrumental neutron activation analysis (INAA) and study

Real-Time Scheduling for Wireless Networks with Random Deadlines

July 26, 2017
Author(s)
Mohamed Hany, Nader Moayeri
The use of wireless communications in industrial environments is motivated by the flexibility that wireless networks provide and their cost-efficient setup and maintenance. Various wireless technologies have been introduced to satisfy the strict industrial

Techniques to Evaluate Terrestrial Laser Scanner Errors

July 26, 2017
Author(s)
Bala Muralikrishnan, Prem K. Rachakonda
Forensic photography has been one of the most important tool for investigators over many decades. They preserve the history of the scene and provides a way for investigators to revisit the scene. However, it is difficult to ascertain any objective

Updated NIST Guidance for Bluetooth Security

July 26, 2017
Author(s)
Lidong Chen, Larry Feldman, Gregory A. Witte
This bulletin summarizes the information in NIST SP 800-121, Revision 2: Guide to Bluetooth Security which provides information on the security capabilities of Bluetooth and provides recommendations to organizations employing Bluetooth wireless

Complex Magnetic Incommensurability and Electronic Charge Transfer through the Ferroelectric Transition in Multiferroic Co 3 TeO 6

July 25, 2017
Author(s)
Chi-Hung Lee, Chin-Wei Wang, Yang Zhao, Wen-Hsien Li, Jeffrey W. Lynn, A. Brooks Harris, Kirrily Rule, Hung-Duen Yang, Helmuth Berger
Polarized and unpolarized neutron diffractions have been carried out to investigate the nature of the magnetic structures and transitions in monoclinic Co 3TeO 6. As the temperature is lowered: below T M1 = 26 K long range order develops, which is fully

Fabrication and Characterization of Humidity Sensors based on CVD Grown MoS2 Thin Film

July 25, 2017
Author(s)
Shiqi Guo, Abbas Arab, Sergiy Krylyuk, Albert Davydov, Mona E. Zaghloul
Recent advances in two-dimensional (2D) transition metal dichalcogenides have demonstrated their potential application in chemical sensors. However, the chemical vapor deposition (CVD) grown molybdenum disulfide (MoS2) humidity sensors are still largely

Cell-based refractometer for pascal realization

July 24, 2017
Author(s)
Patrick F. Egan, Jack A. Stone Jr., Jacob E. Ricker, Jay H. Hendricks, Gregory F. Strouse
We describe a method for determining density of helium via measurements of optical refractivity. In combination with the equation of state, this allows realization of the pascal. Our apparatus is based on the integration of a gas triple-cell into a quasi
