Neutron-Diffraction Measurements of Magnetic Order and a Structural Transition in the Parent BaFe2As2 Compound of FeAs-Based High-Temperature Superconductors

December 17, 2008
Author(s)
Qingzhen Huang, Yiming Qiu, Wei Bao, Mark Green, Jeffrey Lynn, Y. C. Gasparovic, T. Wu, G. Wu, X. H. Chen
The recent discovery of superconductivity in (Ba,K)Fe2As2, which crystallizes in the ThCr2Si2 (122) structure as compared with the LnFeAsO (Ln is lanthanide) systems that possess the ZrCuSiAs (1111) structure, demonstrates the exciting potential of the

Overview of the TREC 2007 Blog Track

December 17, 2008
Author(s)
Ian Soboroff, Craig Macdonald, Iadh Ounis
The goal of the Blog track is to explore the information seeking behaviour in the blogosphere. It aims to create the required in- frastructure to facilitate research into the blogosphere and to study retrieval from blogs and other related applied tasks

Overview of the TREC 2007 Enterprise Track

December 17, 2008
Author(s)
Ian M. Soboroff, Peter Bailey, Nick Craswell, Arjen de Vries
The goal of the enterprise track is to conduct experiments with enterprise data that reflect the experiences of users in real organizations. This year, the track has introduced a new corpus with the goal to be more representative of real-world enterprise

SRM Spotlight

December 17, 2008
Author(s)
Regina R. Montgomery
The SRM Spotlight is a newsletter published by the Measurement Services Division for users of NIST standard reference materials. The Spotlight announces new reference materials and provides information about their use. In addition, this newsletter contains

Technique for Monitoring Environmentally Induced Changes in Polymeric Sealants

December 17, 2008
Author(s)
Donald L. Hunston, Kar T. Tan, Christopher C. White
A new procedure was developed to utilize stress relaxation tests to monitor damage induced in sealant materials exposed to environmental variables and changing strains. By combining tension and compression tests, it was possible to monitor both molecular

Two New Efficient CCA-Secure Online Ciphers : MHCBC and MCBC

December 17, 2008
Author(s)
Mridul Nandi
Online ciphers are those ciphers whose ciphertexts can be computed in an online manner. HCBC1 and HCBC2 are two known examples of Hash Cipher Block Chaining online ciphers. HCBC1 is secure against chosen plaintext adversary (or called CPA-secure) whereas

NDRProfile Schema Version 1.0 User Guide

December 16, 2008
Author(s)
Joshua Lubell, Betty Harvey, Puja Goyal, Katherine C. Morris
The NDRProfile schema provides a common syntax for exchanging, managing, and reusing XML Schema naming and design rules (NDRs). NDRProfile, used by NIST's Quality of Design (QOD) application as a format for import and export of rule sets, is also useful

Measurement of formamidopyrimidines in DNA

December 15, 2008
Author(s)
Pawel Jaruga, Guldal Kirkali, Miral M. Dizdar
Formamidopyrimidines, 4,6-diamino-5-formamidopyrimidine (FapyAde) and 2,6-diamino-4-hydroxy-5-formamidopyrimidine (FapyGua), are among major lesions in DNA generated by hydroxyl radical attack, UV radiation or photosensitization in vitro and in vivo

Synchronization monitoring of I/Q data and pulse carving misalignment for a parallel-type 20-Gb/s RZ-DQPSK transmitter by measuring RF clock tone/low frequency power

December 15, 2008
Author(s)
Jeffrey A. Jargon, Xiaoxia Wu, Laurie Christian, Bo Zhang, Wei-Ren Peng, Jeng-Yuan Yang, Lin Zhang, Scott Nuccio, Loukas Paraschis, Alan Willner
We experimentally demonstrate a technique for monitoring the time misalignment of in-phase/quadrature (I/Q) data streams and pulse carver/data in a 20-Gb/s return-to-zero differential quadrature phase-shift-keying (RZ-DQPSK) transmitter. By measuring the

Calibration of Hygrometers with the Hybrid Humidity Generator

December 14, 2008
Author(s)
Christopher W. Meyer, Joseph T. Hodges, Peter H. Huang, W Wyatt Miller, Dean C. Ripple, Gregory E. Scace
We describe here the calibration of customer hygrometers using a new humidity generator that has been commissioned at the National Institute of Standards and Technology. The NIST Hybrid Humidity Generator (HHG) generates frost/dew points from –70 °C to +85

Multiplexed "Detectorless" Electrophoresis

December 14, 2008
Author(s)
David Ross, Jason Kralj
A new microfluidic electrophoresis device and technique is described that is designed specifically for multiplexed, high throughput separations. The device consists of an array of short (3 mm) capillaries connecting individual sample reservoirs to a common

Design and testing of a software feedback loop for RF power leveling

December 12, 2008
Author(s)
Xiaohai Cui, Thomas P. Crowley
We have developed a software feedback loop that stabilizes the RF power input in calorimetric measurements to better than 30 ppm. In this system, a bolometric sensor with a Type IV power meter is used to detect the power. Feedback is provided to the AM

Durability of Building Joint Sealants

December 12, 2008
Author(s)
Christopher C. White, Kar T. Tan, Donald L. Hunston
Predicting the service life of building joint sealants exposed to service environments in less than real times has been a need of the sealant community for many decades. Despite extensive research efforts have been made to design laboratory accelerated

Mutually consistent thermodynamic potentials for fluid water, ice and seawater: a new standard for oceanography

December 12, 2008
Author(s)
Rainer Feistel, Daniel G. Wright, Kiyoshi Miyagawa, Allan H. Harvey, Jan Hruby, Trevor J. McDougall, David R. Jackett, Wolfgang Wagner
A new seawater standard for oceanographic and engineering applications has been developed that consists of three independent thermodynamic potential functions, derived from extensive distinct sets of very accurate experimental data. The results have been
