Scanning electron microscope measurement of width and shape of 10 nm patterned lines using a JMONSEL-modeled library

July 1, 2015
Author(s)
John S. Villarrubia, Andras Vladar, Bin Ming, Regis J. Kline, Daniel F. Sunday, Jasmeet Chawla, Scott List
The width and shape of 10 nm to 12 nm wide lithographically patterned SiO2 lines were measured in the scanning electron microscope by fitting the measured intensity vs. position to a physics-based model in which the lines’ widths and shapes are parameters

Standardization of Smart Grid Customer Interfaces

July 1, 2015
Author(s)
Steven T. Bushby, David G. Holmberg
One of the key concepts of a modernized “smart grid” is to combine modern communication technology with an improved electric grid to enable energy consumers to exchange information with energy suppliers in order to collaboratively manage electricity supply

Strategy for extensible, evolving terminology for the Materials Genome Initiative efforts

July 1, 2015
Author(s)
Talapady N. Bhat, Ursula R. Kattner, Laura Bartolo, Carelyn E. Campbell, John T. Elliott
Intuitive, flexible, and evolving terminology plays a significant role in capitalizing on recommended knowledge representation models for material engineering applications. In this article we present a proposed rules-based approach with initial examples

Using Check Standard Data to Simplify Uncertainty Estimates

July 1, 2015
Author(s)
Theodore D. Doiron
Uncertainty has proven difficult to implement in calibrations labs. The subject has mathematics and statistics that are part of normal scientific research but are seldom found among working metrologists in small calibration labs. There is, however, a

Applying Thymine Isostere 2,4-Difluoro-5-methylbenzene as an Assignment Tool and Probe of Purine-rich DNA Dynamics Using Proton NMR Spectroscopy

June 30, 2015
Author(s)
Robert G. Brinson, Jennifer T. Miller, Kahn Jason, Stuart F. Le Grice, John P. Marino
Proton assignment of NMR spectra of oligonucleotide duplexes can become difficult with increasing helical length due to cross peak overlap. Here we describe an alternative to 15N and 13C labeling that facilitates assignment via single site substitution

Deuteration in Biological Neutron Reflectometry

June 30, 2015
Author(s)
Frank N. Heinrich
Neutron reflectometry is uniquely positioned in structural biology, because of its ability to characterize biomimetic interfacial architectures like lipid membranes and membrane-associated proteins non-destructively and in their native environment

Development of the IES method for evaluating the color rendition of light

June 30, 2015
Author(s)
Yoshihiro Ohno, Aurelien David, Kevin Houser, Minchen Wei, Michael Royer, Kevin Smet, Lorne Whitehead
We have developed a two-measure system for evaluating light sources’ color rendition that builds upon conceptual progress of numerous researchers over the last two decades. The system quantifies the color fidelity and color gamut (i.e. change in object

Longitudinal Study of Fingerprint Recognition

June 30, 2015
Author(s)
Soweon Yoon, Anil Jain
Human identification by fingerprints is based on the fundamental premise that ridge patterns from distinct fingers are different (uniqueness) and a fingerprint pattern does not change over time (persistence). While the uniqueness of fingerprints has been

Measuring Limits on the Ability of Colluding Countries to Partition the Internet

June 30, 2015
Author(s)
Peter M. Mell, Richard Harang, Assane Gueye
We show that the strength of Internet-based network interconnectivity of countries is increasing over time. We then evaluate bounds on the extent to which a group of colluding countries can disrupt this connectivity. We evaluate the degree to which a group

Preface: Special Issue on Knowledge Driven Robotics and Manufacturing

June 30, 2015
Author(s)
Craig I. Schlenoff, Stephen B. Balakirsky, Edson Prestes
State-of-the-art robots are capable of sub-millimeter movement accuracy. However, they are often programmed by an operator using crude positional controls from a teach pendent. Reprogramming these robots when their task is altered requires that the robot

Sharp interface model of creep deformation in crystalline solids

June 30, 2015
Author(s)
Yuri Mishin, Geoffrey B. McFadden, Robert F. Sekerka, William J. Boettinger
We present a rigorous irreversible thermodynamics treatment of creep deformation of solid mate- rials with interfaces described as geometric surfaces capable of vacancy generation and absorption and moving under the influence of local thermodynamic forces

X-ray Powder Diffraction Studies of (BaxSr1-x)2Co2Fe12O22 and (BaxSr1-x)Co2Fe16O27

June 30, 2015
Author(s)
Winnie K. Wong-Ng, Guangyao Liu, Yonggao Yan, Kevin R. Talley, James A. Kaduk
X-ray structural characterization and X-ray reference powder patterns have been determined for two series of iron- and cobalt-containing layered compounds, namely, (BaxSr1-x)2Co2Fe12O22 (x = 0.2, 0.4, 0.6, 0.8) and (BaxSr1-x)Co2Fe16O27 (x = 0.2, 0.4, 0.6
