Storing and retrieving wavefronts with resistive temporal memory

October 10, 2020
Author(s)
Advait Madhavan, Mark D. Stiles
We extend the reach of temporal computing schemes by developing a memory for multi-channel temporal patterns or "wavefronts." This temporal memory re-purposes conventional one-transistor-one-resistor (1T1R) memristor crossbars for use in an arrival-time

An untargeted approach to determine the authenticity of Ginkgo biloba L. plant materials and dried leaf extracts by liquid chromatography-mass spectrometry (LC-HRMS) and chemometrics.

August 5, 2020
Author(s)
Meryl B. Cruz, Benjamin Place, Laura J. Wood, Aaron A. Urbas, Werickson Rocha, Andrzej Wasik
The lack of stringent regulations regarding raw materials for herbal supplements used for medicinal purposes has been a constant challenge in the industry. Ginkgo biloba L. leaf extracts attract consumers because of the supposed positive effect on mental

Experimental Upper Bound and Theoretical Expectations for Parity-Violating Neutron Spin Rotation in He-4

July 16, 2019
Author(s)
Jeffrey S. Nico, Hans P. Mumm, H E. Swanson, C. D. Bass, T. D. Bass, J M. Dawkins, J C. Horton, D Luo, William M. Snow, S. C. Walbridge, B. E. Crawford, K. F. Gan, A M. Micherdzinska, C. R. Huffer, D M. Markoff, Murad Sarsour, E I. Sharapov, V Zhumabekova, Blayne R. Heckel
Neutron spin rotation is expected from quark-quark weak interactions in the Standard Model, which induce weak interactions among nucleons that violate parity. We present the results from an experiment searching for the effect of parity violation via the

Compression Guidance for 1000 ppi Palm and Hand Friction Ridge Imagery

July 2, 2019
Author(s)
John M. Libert, John D. Grantham, Craig I. Watson
NIST provided in a special publication guidance for the compression of 1000 ppi fingerprint images using Part I of the JPEG 2000 standard. The present document extends the Guidance to the compression of 1000 ppi palm and whole-hand images. The NIST

Headspace Analysis: Purge and Trap

February 15, 2019
Author(s)
Thomas J. Bruno, Megan E. Harries
Headspace analysis is a technique for sampling and examining the volatiles in a solid or liquid sample. The term headspace refers to the volume of vapor above a condensed phase sample. Purge and trap refers to the headspace technique in which volatile

Advanced Maintenance in Manufacturing: Costs and Benefits

September 23, 2018
Author(s)
Douglas Thomas
The costs of maintenance and the potential effect on maintenance costs from adopting predictive maintenance techniques is not well documented at the national level. A number of data items need to be collected to estimate the costs and losses associated

Reasoning about Smart City

Edward R. Griffor, Martin J. Burns, David A. Wollman, Marcello Balducinni, Claire Vishik, Michael Huth
… leadership and the public. The US National Institute of Standards and Technology (NIST) and its government, …

System Lifecycle Handler -- Spinning a Digital Thread for Manufacturing

July 11, 2018
Author(s)
Manas Bajaj, Thomas D. Hedberg Jr.
Transforming the manufacturing economy from paper-based information flows to a seamless digital thread across geographically distributed supply chains has the potential to reduce cycle time by 75% and save manufacturers $30 billion annually. The "Digital
