Evolution of gamma/gamma-prime Microstructure in Ternary Co-Al-W Alloys

June 29, 2015
Author(s)
Eric Lass, Yaakov S. Idell, Carelyn E. Campbell, Ursula R. Kattner
The discovery of a two-phase γ (FCC)-γ' (L12) field in the ternary Co-Al-W phase diagram has sparked significant research interest into possible Co-based analogs to traditional Ni-based superalloys used in turbine engine applications. This work

High-dimensional hyperentanglement of mode-locked two-photon states

June 29, 2015
Author(s)
Zhenda Xie, Tian Zhong, Sajan Shrestha, XinAn Xu, Junlin Liang, Yan-Xiao Gong, Alessandro Restelli, Jeffrey Shapiro, Franco N. Wong, Chee Wei Wong, Joshua Bienfang
Quantum entanglement is the fundamental resource for quantum information processing and communications, including secure data rates with higher capacities and better error resilience [1-9]. In dense-coded quantum communication channels, it is desirable to

PIXEL FUSION BASED STEREO IMAGE RETARGETING

June 29, 2015
Author(s)
Hamid Gharavi
Image retargeting attempts to adapt images to different devices while preserving the salient contents. Most existing methods address retargeting of a single image. In this paper, we propose a novel image retargeting method for resizing a pair of stereo

Advances in the Development of OpenCalphad Software and Databases

June 28, 2015
Author(s)
Bo Sundman, Ursula R. Kattner, Mauro Palumbo, Suzana G. Fries
Thermodynamics is at the core of materials science. The Calphad method, a powerful tool for materials design and engineering applications, has been shown to be an excellent platform for linking experiments and theoretical, quantum mechanics based results

Phase Equilibria and Crystal Chemistry of the CaO-?Sm2O3-CoOz System at 885 degC in Air

June 27, 2015
Author(s)
Winnie K. Wong-Ng, William J. Laws, Saul H. Lapidus, James A. Kaduk
The CaO-¿Sm2O3-CoOz system prepared at 885 °C in air consists of two calcium cobaltate compounds, namely, the 2D thermoelectric oxide solid solution, (Ca3-xSmx)Co4O9-z (0 x 0.5) which has a misfit layered structure, and the 1D Ca3Co2O6 which consists of

Resonant interaction of trapped cold atoms with a magnetic cantilever tip

June 26, 2015
Author(s)
John E. Kitching, Chris Montoya, Jose Valencia, Andrew A. Geraci, Matt Eardley, John M. Moreland
Magnetic resonance in an ensemble of laser-cooled trapped Rb atoms is excited using a micro cantilever with a magnetic tip. The cantilever is mounted on a multi-layer atom chip designed to capture, cool, and magnetically transport cold atoms. The coupling

Changes for Product Labeling for Meats and Poultry with Added Solutions

June 25, 2015
Author(s)
Lisa Warfield
Article announcing the requirements for labeling meats and poultry items resulting from a U.S. Department of Agriculture, Food and Safety Inspection Services release of a ruling effective January 1, 2016. This ruling amends the regulations for descriptive

Tuning Open-Circuit Voltage in Organic Solar Cells with Molecular Orientation

June 24, 2015
Author(s)
Brent Kitchen, Omar Awartani, Regis J. Kline, Terry McAfee, Harald Ade, Brendan T. O'Connor
The role of molecular orientation of a polar conjugated polymer in a polymer-fullerene organic photovoltaic (OPV) cells is investigated. A planar heterojunction (PHJ) OPV cell composed of poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl C61-butyric acid

Addiction to MTH1 protein results in intense expression in human breast cancer tissue as measured by liquid chromatography-isotope-dilution tandem mass spectrometry

June 23, 2015
Author(s)
Erdem Coskun, Pawel Jaruga, Ann-Sofie Jemth, Olga Loseva, Leona D. Scanlan, Alessandro Tona, Mark S. Lowenthal, Thomas Helleday, M Miral Dizdar
MTH1 protein sanitizes the nucleotide pool so that modified 2'-deoxynucleoside triphosphates (dNTPs) cannot be used in DNA replication. Cancer cells require MTH1 to avoid incorporation of modified dNTPs resulting in DNA damage mutations and cell death

Behavior of Axially Loaded Steel Short Columns Subjected to A Localized Fire

June 23, 2015
Author(s)
Chao Zhang, Lisa Y. Choe, Mina S. Seif
Current structural re design approaches are based on uniform heating conditions. Steel short columns in real buildings may be exposed to non-uniform heating conditions in accident res. This paper investigates numerically the behavior of steel short columns

Digital Repository of Mathematical Formulae KLS Seeding Project

June 23, 2015
Author(s)
Howard S. Cohl, Marjorie A. McClain, Bonita V. Saunders, Moritz Schubotz, Cherry Y. Zou, Alex A. Danoff, Azeem S. Mohammed
One initial goal for the DRMF is to seed our digital compendium with fundamental orthogonal polynomial formulae. We have received permission from Springer-Verlag and the authors to use formulae from Chapters 1, 9, and 14 from the book "Hypergeometric

New Second-Preimage Attacks on Hash Functions

June 23, 2015
Author(s)
Elena Andreeva, Charles Bouillaguet, Orr Dunkelman, Pierre-Alain Fouque, Jonathan J. Hoch, John M. Kelsey, Adi Shamir, Sebastien Zimmer
In this work, we present several new generic second-preimage attacks on hash functions. Our first attack is based on the herding attack and applies to various Merkle-Damgard-based iterative hash functions. Compared to the previously known long-message

NIST-TAPPI Workshop on Measurement Needs for Cellulose Nanomaterial

Chelsea S. Davis, Robert J. Moon, Sean Ireland, Linda Johnston, Jo Anne Shatkin, Kim Nelson, E. J. Foster, Aaron M. Forster, Michael T. Postek, Andras Vladar, Jeffrey W. Gilman
A one-day workshop focused on the Measurement Needs for Cellulosic Nanomaterials was organized by the National Institute of Standards and Technology and held in conjunction with the 2014 TAPPI International Conference on Nanotechnology for Renewable

Proximal Capture Dynamics for a Single Biological Nanopore Sensor

June 23, 2015
Author(s)
John J. Kasianowicz
Single nanopore sensors enable capture and analysis of molecules that are driven to the pore entry from bulk solution. However, the distance between an analyte and the nanopore opening limits the detection efficiency. A theoretical basis for predicting
