Constructive Relationships Between Algebraic Thickness and Normality

August 4, 2015
Author(s)
Joan Boyar, Magnus G. Find
We study the relationship between two measures of Boolean functions; "algebraic thickness" and "normality". For a function f, the algebraic thickness is a variant of the "sparsity", the number of nonzero coefficients in the unique F_2 polynomial

Effects of Password Permutation on Subjective Usability Across Platforms

August 4, 2015
Author(s)
Kristen Greene
The current work examines subjective password usability across platforms—desktop, smartphone, and tablet—using system- generated passwords that adhere to the stricter password requirements found in higher-security enterprise environments. This research

Isotopic Labeling of Proteins in Halobacterium salinarum

August 4, 2015
Author(s)
Thomas E. Cleveland, Zvi Kelman
It is often necessary to obtain isotopically labeled proteins containing 15N, 13C or 2H for NMR; and 2H for small-angle neutron scattering (SANS) or neutron diffraction studies. To achieve uniform isotopic labeling, protein expression is most commonly

On-Chip Silicon Waveguide Bragg Grating Photonic Temperature Sensor

August 4, 2015
Author(s)
Nikolai Klimov, Sunil Mittal, Zeeshan Ahmed, Michaela Berger
Resistance thermometry is a time-tested method for temperature measurements. Fundamental limits to resistance-based approaches, spurred our interest in developing photonic temperature sensors as a viable alternative. In this study we demonstrate that our

Secure Hash Standard

August 4, 2015
Author(s)
Quynh H. Dang
This standard specifies hash algorithms that can be used to generate digests of messages. The digests are used to detect whether messages have been changed since the digests were generated. The Applicability Clause of this standard was revised to

SHA-3 Standard: Permutation-Based Hash and Extendable-Output Functions

August 4, 2015
Author(s)
Morris J. Dworkin
This Standard specifies the Secure Hash Algorithm-3 (SHA-3) family of functions on binary data. Each of the SHA-3 functions is based on an instance of the KECCAK algorithm that NIST selected as the winner of the SHA-3 Cryptographic Hash Algorithm

Thermochemical Characterization of Biodiesel Fuels using a Novel Laser-Heating Technique

August 4, 2015
Author(s)
Cary Presser, Ashot Nazarian, Thomas J. Bruno, Jacolin A. Murray, John L. Molloy
A state-of-the-art, rapid laser-heating technique, referred to as the laser-driven thermal reactor, was used to characterize National Institute of Standards and Technology Standard Reference Material (SRM) diesel and biodiesel fuels. Also described are the

Extending the Cybersecurity Digital Thread with XForms

August 3, 2015
Author(s)
Joshua Lubell
The digital thread for cybersecurity enables security technologies and data sources to interoperate. It consists of an integrated collection of languages, taxonomies, and metrics represented using the Extensible Markup Language (XML). A gap in the

Hydrogen induced amorphization of LaMgNi4 phase in metal hydride alloys

August 3, 2015
Author(s)
Leonid A. Bendersky, Haoting Shen, Kwo Young, Taihei Ouchi
Hydrogen induced amorphization (HIA) of the LaMgNi4 phase at 30C was found in three LaMgNi4/LaNi5 two-phase metal hydride (MH)-forming alloys. The amorphization happened at the first dehydrogenation cycle from a fully hydrided alloy, and the process is

Improving Clinical Workflow in Ambulatory Care: Implemented Recommendations in an Innovation Prototype for the Veteran’s Health Administration

August 3, 2015
Author(s)
Svetlana Z. Lowry, Emily S. Patterson, Mala Ramaiah, Michael C. Gibbons, David Brick, Robert Calco, Greg Matton, Anne Miller, Ellen Makar, Jorge Ferrer
The National Institute of Standards and Technology (NIST) presented targeted recommendations from human factors workflow methods that could be used in ambulatory (outpatient) care settings to improve the fit of the Electronic Health Record (EHR) with

INTEGRATING RULE-BASED SYSTEMS AND DATA ANALYTICS TOOLS USING OPEN STANDARD PMML

August 3, 2015
Author(s)
Yunpeng Li, Utpal Roy, Yung-Tsun Lee, Sudarsan Rachuri
Rule-based expert systems such as CLIPS (C Language Integrated Production System) are 1) based on inductive (if-then) rules to elicit domain knowledge and 2) designed to reason new knowledge based on existing knowledge and given inputs. Recently, data

Large effective three-body interaction in a double-well optical lattice

August 3, 2015
Author(s)
Eite Tiesinga, Saurabh Paul
We study ultracold atoms in a double-well (DW) optical lattice and show that the low energy states of a multi-band Bose-Hubbard (BH) Hamiltonian with only pai r-wise interactions is equivalent to an effective single-band Hamiltonian with s trong three-body

Framework for Cloud Usability

August 2, 2015
Author(s)
Brian C. Stanton, Mary F. Theofanos, Karun P. Joshi
Organizations are increasingly adopting cloud-based services to meet their business needs. However, due to the complexity and diversity of cloud systems it is important to evaluate the user experience using within a framework that encompasses the

Localization and Number of Au Nanoparticles in Optically Indexed Cells by FIB Tomography

August 2, 2015
Author(s)
Aric W. Sanders, Kavita M. Jeerage, Ann C. Chiaramonti Debay, Alexandra Curtin
Gold nanoparticles (GNPs) are gaining importance as therapeutic chemical delivery vehicles, medical diagnostic tools, phototherapeutic and contrast enhancement agents. GNPs are uniquely suited for these biological uses because of their chemical stability
