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

June 23, 2015
Author(s)
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

The evolution of carbon nanotube network structure in unidirectional nanocomposites resolved by quantitative electron tomography

June 23, 2015
Author(s)
Bharath NMN Natarajan, Noa Lachman, Thomas F. Lam, Douglas Jacobs, Christian J. Long, Minhua Zhao, Brian L. Wardle, Renu Sharma, James A. Liddle
Carbon nanotube (CNT) reinforced polymers are next-generation, high-performance, multifunctional materials with a wide array of promising applications. The successful introduction of such materials is hampered by the lack of a quantitative understanding of

Cloud-Enabled Prognosis for Manufacturing

June 22, 2015
Author(s)
Robert Gao, Lihui Wang, Roberto Teti, David Dornfeld, Soundar Kumara, Masahiko Mori, Moneer Helu
Advanced manufacturing depends on the timely acquisition, distribution, and utilization of information from machines and processes across spatial boundaries for improved accuracy and reliability in predicting resource needs and allocation, maintenance

Copper-Substituted Iron Telluride: A Phase Diagram

June 22, 2015
Author(s)
Patrick N. Valdivia, Min Gyu Kim, Thomas R. Forrest, Zhijun Xu, Meng Wang, Hui Wu, Leland Harriger, Edith D. Bourret-Courchesne, Robert J. Birgeneau
Metal site alloying of the iron chalcogenides is known to give rise to bulk insulating states with no known analogue in the iron arsenide phase diagrams. We have studied the structure, magnetic, and transport properties of copper substituted iron telluride

Metrology Needs for Predicting Concrete Pumpability

June 22, 2015
Author(s)
Myoungsung Choi, Chiara C. Ferraris, Nicos Martys, Didier Lootens, Van Bui, Trey Hamilton
With the increasing use of pumping to place concrete, the development and refinement of the industry practice to ensure successful concrete pumping is becoming an important need for the concrete construction industry. To date, research on concrete pumping

Quantifying Uncertainty in Accelerometer Sensitivity Studies

June 22, 2015
Author(s)
Andrew L. Rukhin, David J. Evans
Key Comparisons of accelerometers sensitivity measurement are performed to compare the sensitivity of linear accelerometers. The key comparison reference value (KCRV) for charge sensitivity as a function of frequency and the accompanying uncertainty are

The Future of Forensic DNA Analysis

June 22, 2015
Author(s)
John M. Butler
The author's thoughts and opinions on where the field of forensic DNA testing is headed for the next decade are provided in the context of where the field has come over the past 30 years. Like the Olympic motto of "faster, higher, stronger", forensic DNA
