Standardization of 237Np

Author(s)
Lizbeth Laureano-Perez, Ryan P. Fitzgerald, Ronald Colle
The standardization of 237Np was investigated. The certified massic activity for 237Np was obtained by 4 liquid scintillation (LS) counting with correction

Jeffrey S. Nico, A. T. Yue, Maynard S. Dewey, David M. Gilliam, G L. Greene, A. Laptev, William M. Snow, F. E. Wiefeldt
The most precise determination of the neutron lifetime using the beam method was completed in 2005 and reported a result of tau_n = (886.3 ± 1.2 [stat] ± 3.2

Optical Atomic Clocks

Author(s)
Christopher W. Oates, N Poli, P. Gill, G.M. Tino
In the last ten years extraordinary results in time and frequency metrology have been demonstrated. Frequency stabilization techniques for continuous wave

Electro-Thermo-Mechanical Model for Bulk Acoustic Wave Resonators

Author(s)
Eduard Rocas, Juan C. Collado Gomez, Jordi Mateu, Nathan D. Orloff, James C. Booth, Robert Aigner
We present the electro-thermo-mechanical constitutive relations, expanded up to the third order, for a BAW resonator. The relations obtained are implemented

Bounding Defaults in Egress Models

Author(s)
Steve M. Gwynne, Erica D. Kuligowski, Michael Spearpoint, Enrico Ronchi
The developers of egress models are in a difficult position. It is in their interest to develop models that are quick and easy to employ and at the same time to

Viscosity-ratio measurements with capillary viscometers

Author(s)
Robert F. Berg, Eric F. May, Michael R. Moldover
Viscosity-ratio measurements made with capillary viscometers exploit the accurate values of the viscosity of helium calculated ab initio. Accurate values of the

Coexposure to Phytoestrogens and Bisphenol a Mimics Estrogenic Effects in an Additive Manner

Author(s)
Anne Katchy, Caroline Pinto, Philip Jonsson, Trang Nguyen-Vu, Marchela Pandelova, Anne Riu, Karl-Werner Schramm, Daniel Samarov, Jan-Ake Gustafsson, Maria Bondesson, Cecilia Williams
Endocrine-disrupting chemicals (EDC) are abundant in our environment. A number of EDCs, including bisphenol A (BPA) can bind to the estrogen receptors, ERα and

Lead-free and Lead-Based ABO3 Perovskite Relaxors with Mixed-Valence A-Site and B-Site Disorder: A Comparative Neutron Scattering Structural Study of (NaYd1/2^Bi1/2)TiOd3^ and Pb(MgYd1/3^Nb2/3)O3

Author(s)
Wenwei Ge, Christopher P. Devreugd, Daniel Phelan, Qinhui Zhang, Muhtar Ahart, Jiefang Li, Haosu Luo, Lynn A. Boatner, Dwight Viehland, Peter M. Gehring
We report the results of neutron elastic scattering measurements between -250°C and 620°C on the lead-free relaxor Na 1/2Bi 1/2TiO 3 (NBT). Strong, anisotropic

Prototype Phantoms for Characterization of Ultra-Low Field Magnetic Resonance Imaging

Author(s)
Michael A. Boss, John A. Mates, Sarah E. Busch, Paul SanGiorgio, Stephen E. Russek, Kai Buckenmaier, Kent D. Irwin, Hsiao-Mei Cho, Gene C. Hilton, John Clarke
Purpose: Prototype phantoms were designed, constructed, and characterized for the purpose of calibrating ultralow field magnetic resonance imaging (ULF MRI)

ToF-SIMS 3D Imaging of Native and Non-Native Species within HeLa Cells

Author(s)
Jeremy Brison, Michael A. Robinson, Danielle S. Benoit, Shinichiro Muramoto, Patrick S. Stayton, David G. Castner
In this study, a non-native chemical species, bromodeoxyuridine (BrdU), was imaged within single HeLa cells using time-of-flight secondary ion mass spectrometry
