Spherical indentation testing of poroelastic relaxations in thin hydrogel layers

December 16, 2011
Author(s)
Edwin Chan, Yuhang Hu, Peter M. Johnson, Zhigang Suo, Christopher Stafford
In this work, we present the Poroelastic Relaxation Indentation (PRI) testing approach for quantifying the mechanical and transport properties of thin layers of poly(ethylene glycol) hydrogel materials with thicknesses on the order of 200 m. Specifically

Atomistic Ensemble Modeling and Small-Angle Neutron Scattering of Intrinsically Disordered Protein Complexes: Applied to Minichromosome Maintenance Protein

December 15, 2011
Author(s)
Susan Krueger, Jae-Ho Shin, Sindhushree NMN Raghunandan, Joseph E. Curtis, Zvi Kelman
The minichromosome maintenance (MCM) proteins are thought to function as the replicative helicases in archaea and eukarya. The solution structure of the N-terminal portion of the MCM complex from the archaeon Methanothermobacter thermautotrophicus {N-mtMCM

Experimentally Based Methodology for Charge Pumping Bulk Defect Trapping Correction

December 15, 2011
Author(s)
Jason T. Ryan, Richard G. Southwick, Jason P. Campbell, Kin P. Cheung, Chadwin Young, John S. Suehle
We develop a simple experimental approach to remove bulk trap contributions from charge pumping data collected on devices which suffer from large amounts of bulk dielectric electron trapping. The approach is more desirable and easier to implement than

Seafood - Good Quantity Control Practices

December 15, 2011
Author(s)
David A. Sefcik
Webinar will identify the 4 primary components of a packaging system and help stakeholders know and recognize the 12 good quantity control practices, as outlined in HB 130. It will also teach them the criteria for evaluating their suppliers quantity

The Infrared Spectrum of NN...CO+ Trapped in Solid Neon

December 15, 2011
Author(s)
Warren E. Thompson, Marilyn E. Jacox
Codeposition of a Ne:N2:CO = 200:1:1 mixture at 4.3 K with a beam of very pure neon atoms excited to their energy levels between 16.6 and 16.85 eV leads to stabilization in the resulting solid of sufficient NNCO+ for detection of its NN- and CO-stretching

When Does a Circuit Really Fail?

December 15, 2011
Author(s)
Jason T. Ryan, Lan Wei, Jason P. Campbell, Richard G. Southwick, Kin P. Cheung, Tony Oates, Phillip Wong, John S. Suehle

A METHOD FOR DETERMINING THE ENVIRONMENTAL FOOTPRINT OF INDUSTRIAL PRODUCTS USING SIMULATION

December 14, 2011
Author(s)
Erik Lindskog, Linus Lundh, Jonatan K. Berglund, Yung-Tsun Lee, Anders Skoogh, Bjorn Johansson
Effective assessment and communication of environmental footprint is increasingly important to process development and marketing purposes. Traditionally, static methods have been applied to analyze the environmental impact during a product's life cycle

Energy Efficiency Analysis for a Casting Production System

December 14, 2011
Author(s)
Jonatan K. Berglund, John L. Michaloski, Swee K. Leong, Guodong Shao, Frank H. Riddick, Jorge Arinez, Stephan Biller
A growing number of manufacturing industries are initiating efforts to address sustainability issues. A study by the National Association of Manufacturers indicated that the manufacturing sector currently accounts for over a third of all energy consumed in

Electronic structures of lithium battery interphase compounds: comparison between inelastic x-ray scattering measurements and theory

December 13, 2011
Author(s)
Eric L. Shirley, Timothy Fister, Moritz Schmidt, Paul Fenter, Christopher Johnson, Michael Slater, Maria K. Chan
In lithium ion batteries, decomposition of the electrolyte near an electrode surface can play a crucial role in determining the device’s long-term performance. The reactivity and the low core binding energy of lithium, carbon, oxygen, and fluorine have

Report of the 96th National Conference on Weights and Measures (2011) SP1125

December 13, 2011
Author(s)
Linda D. Crown, Tina G. Butcher, Steven E. Cook, Richard A. Harshman, Lisa Warfield, David A. Sefcik
The 96th Annual Meeting of the National Conference on Weights and Measures (NCWM) was held July 17 to 21, 2011, at the Holiday Inn Downtown at the Park, Missoula, Montana. The theme of the meeting was Educating Today for Tomorrow. Reports by the NCWM Board

Universal Low-rank Matrix Recovery from Pauli Measurements

December 12, 2011
Author(s)
Yi-Kai Liu
We study the problem of reconstructing an unknown matrix M of rank r and dimension d using O(rd poly log d) Pauli measurements. This has applications in quantum state tomography, and is a non- commutative analogue of a well-known problem in compressed

Extracting Hierarchies With Overlapping Structure From Network Data

December 11, 2011
Author(s)
Brian D. Cloteaux
Relationships between entities in many complex systems, such as the Internet and social networks, have a natural hierarchical organization. Understanding these inherent hierarchies is essential for creating models of these systems. Thus, there is a recent
