Common-Arm Counter-Propagating Interferometer for Fiber Vibration Measurements

November 1, 2011
Author(s)
Craig W. Nelson, Archita Hati, David A. Howe
We propose and demonstrate a novel technique to measure the vibration sensitivity of two-port fiber-based optical components. It uses a common-arm counter-propagating frequency-shifted interferometer that cancels the vibration induced phase noise of the

Discovery of giant magnetostriction in annealed Co1-xFex thin-films

November 1, 2011
Author(s)
Dwight Hunter, William Alexander Osborn, Ke Wang, Nataliya Kazantseva, Jason Hattrick-Simpers, Richard Suchoski, Ryota Takahashi, Marcus L. Young, Apurva Mehta, Leonid A. Bendersky, Sam E. Lofland, Manfred Wuttig, Ichiro Takeuchi
Chemical and structural heterogeneity and resulting interaction of coexisting phases can lead to extraordinary behaviors in oxides as observed in piezoelectric materials at morphotropic phase boundaries and relaxor ferroelectrics. But such phenomena are

Effect of Neutron Irradiation on Dosimetric Properties of the TLD-600H (Lif6:Mg,Cu,P)

November 1, 2011
Author(s)
Alexander A. Romanyukha, Ronaldo Minniti, M. Moscovitch, Alan Keith Thompson, F. Trompier, Ronald Colle, A Sucheta, S. P. Voss, L. A. Benevides
Ideally, dosimeters should measure the dose without their dosimetric properties being affected by the radiation type being measured. Industry-wide occupational radiation workers that can be potentially exposed to neutron radiation fields are routinely

Findings and Recommendations from the Joint NIST AGA Workshop on Odor Masking

November 1, 2011
Author(s)
Thomas J. Bruno, Nancy Rawson, Ali Quaraishi
Since the days of the alchemist, the observation that some substances have a smell while other substances do not has been a source of fascination. The sense of smell, or olfaction, is our least understood sense, however it is important for many human

Home Cooking Fire Mitigation: Technology Assessment. Final Report.

November 1, 2011
Author(s)
Joshua Dinaburg, Daniel T. Guttuk
Cooking related fires are a leading cause of U.S. fire loss. Beginning in the mid 1980's, the National Institute of Standards and Technology, Consumer Product Safety Commission, and the home appliance industry undertook a comprehensive review 1 of

Local Weak Ferromagnetism in Single-Crystalline Ferroelectric BiFeO 3

November 1, 2011
Author(s)
M. Ramazanoglu, M. Laver, William D. Ratcliff, Shannon M. Watson, Wangchun Chen, Andrew Jackson, Karunakar NMN Kothapalli, Seongsu Lee, S.- W. Cheong, V. Kiryukhin
Polarized small-angle neutron scattering studies of single-crystalline multiferroic BefeO 3 reveal a long-wavelength spin density wave generated by 1° spin canting of the spins out of the rotation plane of the antiferromagnetic cycloidal order. This

Mobile-App Addiction: Threat to Security?

November 1, 2011
Author(s)
George Hurlburt, Jeff Voas, Keith Miller
Giving individuals this kind of information processing power, along with unprecedented connectivity, might be the single most impressive technical achievement of the 21st century. Nobody knows what the full impact of this transformation will be, but it's

Modeling Produces Insight into Fire Behavior

November 1, 2011
Author(s)
Adam M. Barowy, Daniel M. Madrzykowski
The National Institute of Standards and Technology (NIST) is the leader in the development of computer-based fire models that simulate the movement of fire gases and heat through a building and estimate the response of various fire protection systems. NIST

Moments of the Truncated Complex Gaussian Distribution

November 1, 2011
Author(s)
Ryan J. Pirkl
We present arbitrary moments of the univariate and bivariate truncated complex Gaussian distribution. Using these moment expressions, we investigate the convergence of a particular infinite series of moments encountered in recent statistical analyses of

Pinhole X -ray camera photos of an ECR ion source plasma

November 1, 2011
Author(s)
Lawrence T. Hudson, Sandor Biri, E Takacs, R. Racz, J. Palinkas
A 70 micrometer pinhole and an X-ray CCD camera in single photon counting mode were used to obtain spatially and spectral resolved images of an electron cyclotron resonance (ECR) ion source generated plasma. The method has good spatial resolution as well

The Latest and Greatest NIST PCR-based DNA Profiling Standard: Updates and Status of Candidate Standard Reference Material (SRM) 2391c

November 1, 2011
Author(s)
Margaret C. Kline, Carolyn R. Steffen, Jamie L. Almeida, Erica L. Romsos, Michael D. Coble, John M. Butler
Standard Reference Material 2391c (SRM 2391c) PCR-based DNA Profiling Standard is the third renewal of this SRM, originally released in 1995. SRM 2391c consists of 6 candidate components labeled A through F. Components A through D are supplied as genomic

Tips and tools for digitizing a museum collection

November 1, 2011
Author(s)
Regina L. Avila, Susan A. Sanders, Keith R. Martin
This article is a "how to guide" for directing and managing a museum photography project. It is based on what the NIST Research Library learned as we went through the process of gathering and photographing museum objects, organizing the digital images, and
