Polarized neutron beam properties for measuring parity-violating spin rotation in liquid He4

December 14, 2010
Author(s)
A M. Micherdzinska, C. D. Bass, T. D. Bass, K. F. Gan, D Lou, D M. Markoff, Hans Pieter Mumm, Jeffrey S. Nico, A. K. Opper, E I. Sharapov, M Snow, H E. Swanson, V Zhumabekova
Measurements of parity-violating neutron spin rotation can provide insight into the poorly nderstood nucleon-nucleon weak interaction. Because the expected rotation angle per unit length is small (10−7 rad/m), several properties of the polarized cold

Zone-Refinement Effect in Small Molecule-Polymer Blend Semiconductors for Organic Thin Film Transistors

December 14, 2010
Author(s)
Yeon Sook Chung, Nayool Shin, Jihoon Kang, Youngeun Jo, Vivek Prabhu, Regis J. Kline, John E. Anthony, Do Y. Yoon
The blend films of small molecule semiconductors with insulating polymers exhibit not only an excellent solution processability, but also superior performance characteristics (field-effect mobility, on/off ratio, threshold voltage and stability) over those

Free and Open Source Software

December 13, 2010
Author(s)
Keith Miller, Jeff Voas, Tom Costello
In this paper, free and open source software are discussed. Open source is an intellectual property destroyer. Nothing could be worse than this for the software business and the intellectual-property business. Microsoft has an official open source presence

Mobile Applications: the Fifth Cycle

December 13, 2010
Author(s)
George Hurlburt, Jeff Voas, Keith Miller
Using the analogy of an existing smart car, this paper explores Power to the Edge , where the edge is commercial mobile computing. The world is poised for a 5th Cycle of computer capability, this time focused on the burgeoning phenomena of mobile computing

Ordered metal nanostructure self-assembly using metal-organic frameworks as templates

December 13, 2010
Author(s)
Benjamin Jacobs, Houk Ronald, Stephen House, Ian Robertson, Albert A. Talin, Mark Allendorf, Mitchell Anstey
Synthesis of metal nanoparticles and nanowires with controlled size and aspect ratio is well developed,1-4 but the creation of ordered nanostructures comprising these is much more challenging, presenting a barrier to further development of electronic and

Speeding up the Wide-Pipe: Secure and Fast Hashing

December 12, 2010
Author(s)
Mridul Nandi, Souradyuti Paul
In this paper we propose a new sequential mode of operation – the Fast wide pipe or FWP for short - to hash messages of arbitrary length. The mode is shown to be (1) preimage-resistance preserving, (2) collision-resistance-preserving and, most importantly

A Knowledge Sharing Framework for Homeland Security Modeling and Simulation

December 10, 2010
Author(s)
Sanjay Jain, Charles W. Hutchings, Yung-Tsun T. Lee, Charles McLean
Modeling and simulation (M&S) tools and capabilities can enable understanding of the complex nature of systems in various homeland security domains. A coordinated effort across government, industry, and academia would advance capabilities in this important

Generalized ellipsometry of artificially designed line width roughness

December 10, 2010
Author(s)
Martin Foldyna, Thomas A. Germer, Brent Bergner, Ronald G. Dixson
We use azimuthally-resolved spectroscopic Mueller matrix ellipsometry to study a periodic silicon line structure with and without artificially-generated line width roughness (LWR). We model the artificially perturbed grating using 1D and 2D rigorous

k-Zero Day Safety: Measuring the Security Risk of Networks Against Unknown Attacks

December 10, 2010
Author(s)
Lingyu Wang, Sushil Jajodia, Anoop Singhal, Steven Noel
The security risk of a network against unknown zero day attacks has been considered as something unmeasurable since software flaws are less predictable than hardware faults and the process of finding such flaws and developing exploits seems to be chaotic

Modeling of Self-Heating Mechanism in the Design of Superconducting Limiters

December 10, 2010
Author(s)
Eduard Rocas, Juan C. Collado Gomez, Jordi Mateu, Nathan D. Orloff, James C. Booth
This work proposes a modeling method to simulate how temperature rise, due to power dissipation, affects the performance of a HTS limiter. The spatial temperature rise distribution across and along a HTS transmission line is determined by heat generation

Low loss superconducting titanium nitride coplanar waveguide resonators

December 9, 2010
Author(s)
Michael Vissers, Jiansong Gao, David S. Wisbey, David P. Pappas, C. C. Tsuei, A. D. Corcoles, Matthias Steffen
Thin films of TiN were sputter-deposited onto Si and sapphire wafers with and without SiN buffer layers. The films were fabricated into RF coplanar waveguide resonators, and internal quality factor measurements were taken at millikelvin temperatures in

Far-ultraviolet signatures of the 3He(n,tp) reaction in noble gas mixtures

December 8, 2010
Author(s)
Patrick Hughes, Alan K. Thompson, Michael Coplan, Robert E. Vest, Charles W. Clark
Previous work showed that the 3He(n,tp) reaction in a cell of 3He at atmospheric pressure generated tens of far-ultraviolet photons per reacted neutron. Here we report amplification of that signal by factors of 1000 and more when noble gases are added to

Mapping Crystal Orientation in High Performance Thienothiophene Copolymer Thin Films

December 8, 2010
Author(s)
Xinran Zhang, Steven D. Hudson, Dean M. DeLongchamp, David J. Gundlach, Martin Heeney, Iain McCulloch
Mapping of crystalline grain orientation for solution-processed semiconducting polymer thin films is key to understanding charge transport in electronic devices based on them and yet challenging. In this work, a high mobility thienothiophene copolymer

Toward Objective Global Privacy Standards

December 8, 2010
Author(s)
Ari M. Schwartz
Technical standards offer a new ability to support the important public policy goal of better protecting privacy. To do so most effectively, we must begin to move from the privacy standards based on subjective and procedural efforts to a series of
