Incorporating D3.js Information Visualization into Immersive Virtual Environments

April 9, 2015
Author(s)
Wesley N. Griffin, Luis D. Catacora, Jeffrey W. Bullard, Judith E. Terrill
We have created an integrated interactive visualization and analysis environment that can be used immersively or on the desktop to study a simulation of microstructure development during hydration or degradation of cement pastes and concrete. Our

Password Entry Errors: Memory or Motor?

April 9, 2015
Author(s)
Kristen Greene, Frank Tamborello
As we increasingly rely upon our computer information systems to store and operate on sensitive information, the methods we use to authenticate user identity also become more important. One of the most important such methods is the password. However

Towards a "Periodic Table" of Bugs

April 8, 2015
Author(s)
Irena Bojanova
Our vision for a "periodic table" of bugs is a "natural" organization of a catalog or dictionary or taxonomy to describe software weaknesses and vulnerabilities. Such an organization will help the community to: a) more closely explain the nature of

Elemental characterization of Single-Wall Carbon Nanotube (SWCNT-1) reference material by neutron and prompt gamma activation analysis

April 7, 2015
Author(s)
Rick L. Paul, Rabia Oflaz, Jan Kucera, J W Bennett, E. A. De Nadai Fernandes, M. Kubesova, M. A. Bacchi, A. J. Stopic, R. E. Sturgeon, P. Grinberg
Instrumental neutron activation analysis with both relative and k0 standardization was used in four experienced laboratories to determine element mass fractions in single-wall carbon nanotube certified reference material (CRM) SWCNT-1. Results obtained

Rolled-Up Nanoporous Membranes by Nanoimprint Lithography and Strain Engineering

April 7, 2015
Author(s)
Jaehyun Park, ChangKyu Yoon, Qianru Jin, Lei Chen, David . Gracias
It is extremely challenging to enable nanoscale patterning in three dimensional (3D) curved geometries using conventional nanolithographic approaches. In this paper, we describe a highly parallel approach that combines nanoimprint lithography (NIL) and

Angular dependence of spin-orbit spin-transfer torques

April 6, 2015
Author(s)
Ki-Sueng Lee, Dongwook Go, Aurelien Manchon, Paul M. Haney, Mark D. Stiles, Hyun-Woo Lee, Kyung Jin Lee
In ferromagnet/heavy metal bilayers, an in-plane current gives rise to spin-orbit spin transfer torques. For two-dimensional free-electron and tight-binding models with Rashba spin-orbit coupling, these torques acquire nontrivial dependence on the

Building a Spring-Transport Mechanism for Spinning Rotor Gauges

April 3, 2015
Author(s)
James A. Fedchak, Julia K. Scherschligt, Makfir Sefa, Nick Phandinh
Spinning rotor gauges (SRGs) are widely used as transfer standards in inter-laboratory comparisons and as secondary standards by calibration laboratories. In both of these applications, it is necessary to ship the SRG for calibration, often internationally

Frequency-agile, rapid scanning cavity ring-down spectroscopy (FARS-CRDS) measurements of the (30012) --(00001) near-infrared carbon dioxide band

April 3, 2015
Author(s)
David A. Long, Szymon S. Wojtewicz, Charles E. Miller, Joseph T. Hodges
We present new high accuracy measurements of the (30012)←(00001) CO¬2 band near 1575 nm recorded with a frequency-agile, rapid scanning cavity ring-down spectrometer. The resulting spectra were fit with the partially correlated, quadratic-speed-dependent

ACT-R Modeling of Password Entry Errors

April 2, 2015
Author(s)
Kristen Greene, Franklin Tamborello
Validated predictive models of human error for password-related tasks could better inform password requirements for both government and civilian systems. Here, we build upon prior modeling work focused on disentangling the source of password entry errors

Analysis of VAES3 (FF2)

April 2, 2015
Author(s)
Morris J. Dworkin, Ray A. Perlner
The National Institute of Standards and Technology (NIST) specified three methods for format-preserving encryption (FPE) in Draft NIST Special Publication (SP) 800-38G, which was released for public comment in July, 2013. Each method was a mode of

Report on the FG 2015 Video Person Recognition Evaluation

April 2, 2015
Author(s)
P J. Phillips, J. R. Beveridge, Hao Zhang, Bruce A. Draper, Patrick J. Flynn, Zhenhua Feng, Patrik Huber, Josef Kittler, Zhiwu Huang, Shaoxin Li, Yan Li, Meina Kan, Ruiping Wang, Shiguang Shan, Xilin Chen, Haoxiang Li, Hua Gang, Vitomir Struc, Janez Krizaj, Changxing Ding, Dacheng Tao

Shape-changing magnetic assemblies as high-sensitivity NMR-readable nanoprobes

April 2, 2015
Author(s)
Gary Zabow, Stephen Dodd, Alan Koretsky
Fluorescent and plasmonic probes have proven invaluable in the life sciences, but function poorly in optically inaccessible regions. Here we present radio-frequency addressable analogs that afford sensing opportunities similar to those of fluorescent
