Surface conductance and microwave scattering in semicontinous gold films

September 28, 2015
Author(s)
Jan Obrzut
Semicontinous gold films 4 nm to 12 nm thick were characterized using patterned coplanar waveguides over a frequency range of 100 MHz to 20 GHz. Such films can form two dimensional fractal aggregates mixed with dielectric voids with unusually large

Topological Magnon Bands in Kagome Lattice Ferromagnet

September 28, 2015
Author(s)
Robin Michael Daub Chisnell, Joel Helton, D. E. Freedman, D. K. Singh, R. I. Bewley, D. G. Nocera, Y. S. Lee
The success of band theory in describing the motion of quantum particles inside solids is a foundational accomplishment in modern physics. Recent excitement has centered on systems for which the bands are topological. Such materials possess novel

The Optics and Alignment of the Divergent Beam Laboratory X-ray Powder Diffractometer and its Calibration with NIST Standard Reference Materials

September 25, 2015
Author(s)
James P. Cline, Marcus H. Mendenhall, David R. Black, Donald A. Windover, Albert Henins
The laboratory X-ray powder diffractometer is one of the primary analytical tools in materials science. It is applicable to nearly any crystalline material, and with advanced data analysis methods, it can provide a wealth of information concerning sample

An algorithm for compensation of short-period errors in optical encoders

September 24, 2015
Author(s)
Marcus H. Mendenhall, Donald A. Windover, Albert Henins, James P. Cline
We present a simple way to collect data from an optical position or angle encoder with a readout which interpolates values between the optical features, and to process this data set so as to determine the short-range errors which arise from an

Some dual definite integrals for Bessel functions

September 24, 2015
Author(s)
Howard S. Cohl, Rebekah M. Palmer, Sean Nair
Based on known definite integrals of Bessel functions of the first kind, we obtain exact solutions to unknown definite integrals using the method of integral transforms from Hankel's transform.

Benchmarks for genome sequencing

September 23, 2015
Author(s)
Justin M. Zook, Marc L. Salit
In this issue, Griffith et al. present one of the most comprehensive genome-sequence data sets to date from a patient with myeloid leukemia, including sequencing of normal tissue, primary cancer, and a relapse. Their raw data from a variety of sequencing

Infiltration and Ventilation in a Very Tight Home

September 23, 2015
Author(s)
Lisa C. Ng, Andrew K. Persily, Steven J. Emmerich
The Net Zero Energy Residential Test Facility (NZERTF) was constructed at the National Institute of Standards and Technology (NIST) to support the development and adoption of cost-effective net zero energy designs and technologies. Key design objectives

Sequence-based Analysis of Stutter at STR Loci: Characterization and Utility

September 23, 2015
Author(s)
Rachel A. Aponte, Katherine Gettings, David L. Duewer, Michael D. Coble, Peter Vallone
The development of next generation sequencing (NGS) technologies creates the potential for changing the method by which the forensic science community genotypes short tandem repeat (STR) loci. While the capabilities of NGS are promising, moving from
