GenApp Module Execution and Airavata Integration

November 1, 2014
Author(s)
Emre H. Brookes, Nadeem Anjum, Joseph E. Curtis, Suresh Marru, Raminder Singh, Marlon Pierce
A new framework (GenApp) for rapid generation of scientific applications running on a variety of systems including science gateways has recently been developed. This framework builds a user interface for a variety of target environments on a collection of

Toward Smart Manufacturing Using Decision Guidance Analytics

November 1, 2014
Author(s)
Alexander Brodsky, Mohan Krishnamoorthy, Daniel A. Menasce, Guodong Shao, Sudarsan Rachuri
This paper is focused on decision analytics for smart manufacturing. We consider temporal manufacturing processes with stochastic throughput and inventories. We demonstrate the use of the recently proposed concept of the decision guidance analytics

Earthquake-Resilient Lifelines: NEHRP Research, Development and Implementation Roadmap

October 31, 2014
Author(s)
Thomas O'Rourke, Laurie Johnson, Craig Davis, Leonardo Duenas-Osorio, Anne Kiremidjian, Alexis Kwasinski, Michael Mahoney, Stuart Nishenko, Douglas Nyman, Chris Poland, Alex Tang
The primary objective of this task order was to develop a 10-year research, development, and implementation roadmap for generating new model earthquake-resilient design and construction standards for key lifeline systems and components. The starting point

Impact of BTI on Random Logic Circuit Critical Timing

October 31, 2014
Author(s)
Kin P. Cheung, Jiwu Lu, Guangfan Jiao, Jason P. Campbell, Jason T. Ryan
Bias temperature instability (BTI) is known to be a serious reliability issue for state-of-the-art Silicon MOSFET technology [1-6]. It is well-known that in addition to a “permanent” degradation, there is a large recoverable degradation component [7] that

Mechanisms of aging and release from weathered nanocomposites

October 31, 2014
Author(s)
Tinh Nguyen, Wendel Wohlleben, Li Piin Sung
Polymer nanocomposites are increasingly used in outdoor structures. However, polymers are susceptible to degradation by solar ultraviolet (UV) radiation, which potentially releases nanofiller during polymer nanocomposites' life cycle. Such release may pose

Structural and Dynamical Studies of Acid Mediated Conversion in Amorphous-Calcium-Phosphate Based Dental Composites

October 31, 2014
Author(s)
Fan Zhang, Andrew Allen, Lyle E. Levine, Mark D. Vaudin, Drago Skrtic, Joseph M. Antonucci, Kathleen Hoffman, Anthony A. Giuseppetti, Jan Ilavsky
Amorphous calcium phosphate (ACP) based composites are promising restorative dental materials attributable to ACP's capacity to release calcium and phosphate ions through a complex reaction in which ACP is converted to its crystalline, apatitic form

Frequency Comb Generation in Superconducting Resonators

October 30, 2014
Author(s)
Robert P. Erickson, Michael Vissers, Martin O. Sandberg, Steven R. Jefferts, David P. Pappas
We have generated frequency combs spanning 0.5 to 20 GHz in superconducting λ=2 resonators at T ¼ 3 K. Thin films of niobium-titanium nitride enabled this development due to their low loss, high nonlinearity, low frequency dispersion, and high critical

NIST Micronutrients Measurement Quality Assurance Program Summer 2013 Comparability Studies: Results for Round Robin LXXIV Fat-Soluble Vitamins and Carotenoids in Human Serum and Round Robin 39 Ascorbic Acid in Human Serum

October 30, 2014
Author(s)
Jeanice M. Brown Thomas, David L. Duewer
The National Institute of Standards and Technology coordinates the Micronutrients Measurement Quality Assurance Program (MMQAP) for laboratories that measure fat- and water-soluble vitamins and carotenoids in human serum and plasma. This report describes

Frequency-Comb-Based Remote Sensing of Greenhouse Gases over Kilometer Air Paths

October 29, 2014
Author(s)
Greg B. Rieker, Fabrizio R. Giorgetta, William C. Swann, Jonathan Kofler, Alexander M. Zolot, Laura C. Sinclair, Esther Baumann, Christopher L. Cromer, G. Petron, Colm Sweeney, P P. Tans, Ian R. Coddington, Nathan R. Newbury
We demonstrate frequency comb tooth-by-tooth measurements of atmospheric gas absorption across a 2-km, turbulent, open-air path through coherent dual-comb spectroscopy. High accuracy, high signal-to-noise transmission spectra are acquired spanning 5990 to
