Far-Infrared Two-Phonon Absorption in GaP and GaAs

Author(s)
Simon G. Kaplan, H M. Lawler, Eric L. Shirley, S Bhat, M E. Thomas
We present detailed temperature dependent absorption spectra of GaP and GaAs at wavenumbers from 20 cm-1 to 350 cm-1 and temperatures between 10 K and 295 K...

Coercivities Above 10 kOe in CoPd Superlattices

Author(s)
William F. Egelhoff Jr., Cedric J. Powell, L Gan, P J. Chen, H Ettedgui, D Tirosh, Robert D. McMichael, Mark D. Stiles, J Mallett, Alexander J. Shapiro, John E. Bonevich, J H. Judy, Erik B. Svedberg, A. E. Berkowitz
We have achieved excellent grain isolation in CoPd superlattices by using 10 nm Au as both an underlayer and an overlayer and diffusing Au into the grain...

Dynamic Calibration for Instruments

Author(s)
Robert C. Hagwood
The NIST Pressure Measurements Division provides calibration service for pressure instruments that customers in turn use to calibrate other instruments. Often...

Dynamics of DNA in and Around a Nanopore

Author(s)
Robert C. Hagwood
Single stranded DNA is modeled as a flexible polymer. The motion of such DNA in a vessel partitioned by a membrane containing a cylindrical nanopore is modeled...

An Automated Acoustic System to Monitor and Classify Birds

Author(s)
C. Kwan, K C. Ho, G. Mei, Y Li, Z. Ren, R. Xu, Y. Zhang, R. Lao, M. Stevenson, Vincent M. Stanford, C. Rochet
This paper presents a novel bird monitoring and recognition system in noisy environments. The project objective is to avoid bird strikes to aircraft. First, a...

Troubleshooting Key Comparisons

Author(s)
Adriana Hornikova, William F. Guthrie
Key Comparisons are international inter-laboratory studies used to establish the degree of equivalence between national measurement standards. These studies...

Emerging Metrology for High Throughput Nanomaterial Genotoxicology

Author(s)
Bryant C. Nelson, Christa W. Wright, Yuko Ibuki, Maria Moreno-Villanueva, Hanna L. Karlsson, Giel Hendriks, Christopher M. Sims, Neenu Singh, Shareen H. Doak
The rapid development of the engineered nanomaterial (ENM) manufacturing industry has accelerated the incorporation of ENMs into a wide variety of consumer...

Toward Clean Suspended CVD Graphene

Author(s)
Alexander Yulaev, Guangjun Cheng, Angela R. Hight Walker, Ivan Vlassiouk, Alline Myers, Marina S. Leite, Andrei Kolmakov
The application of suspended graphene as electron transparent supporting media in electron microscopy, vacuum electronics, and micromechanical devices requires...

Evidence against solar influence on nuclear decay constants

Author(s)
Denis E. Bergeron, Ryan P. Fitzgerald, Leticia S. Pibida, Stefaan Pomme
The exponential decay of radionuclides as a function of time is a cornerstone of nuclear physics and radionuclide metrology. Decay constants for spontaneous...

Artifacts in magnetic measurements of fluid samples

Author(s)
Cindi L. Dennis, Zoe A. Boekelheide
Applications of magnetic fluids are ever increasing, as well as the corresponding need to be able to characterize these fluids in situ. Commercial magnetometers...

Separating OR, SUM, and XOR Circuits

Author(s)
Magnus G. Find, Mika Goos, Matti Jarvisalo, Petteri Kaski, Miko Koivisto, Janne Korhonen
Given a boolean n x n matrix A we consider arithmetic circuits for computing the transformation x 7! Ax over different semirings. Namely, we study three circuit...

Whatever Happened to Formal Methods for Security?

Author(s)
Kim B. Schaffer, Jeffrey M. Voas
We asked 7 experts 7 questions to find out what has occurred recently in terms of applying formal methods (FM) to security-centric, cyber problems. We were...
