Shear Bond Strength of Bioactive Amorphous Calcium Phosphate Composites

November 1, 2007
Author(s)
Gary E. Schumacher, Joseph M. Antonucci, Justin N. O'Donnell, Drago Skrtic
Bioactive, amorphous calcium phosphate (ACP)-filled polymeric composites in aqueous environments release significant amounts of Ca and PO4 ions leading to deposition of an apatitic mineral that is similar to that found in enamel. These materials are

Subpicotesla atomic magnetometry with a microfabricated vapour cell

November 1, 2007
Author(s)
V Shah, Svenja A. Knappe, P Schwindt, John E. Kitching
Highly sensitive magnetometers, capable of measuring magnetic fields below 1 pT, impact areas as diverse as geophysical surveying1, the detection of unexploded ordinance, space science3, nuclear magnetic resonance (NMR), and perimeter and remote monitoring

The Marine Optical BuoY (MOBY) Radiometric Calibration and Uncertainty Budget for Ocean Color Satellite Sensor Vicarious Calibration

November 1, 2007
Author(s)
Steven W. Brown, S Flora, M Feinholz, M Yarbrough, Terrance Houlihan, D Peters, Yong S. Kim, J Mueller, Bettye C. Johnson, Dennis Clark
For the past decade, the Marine Optical Buoy (MOBY), an autonomous radiometric buoy stationed in the waters off Lanai, Hawaii, has been the primary in-water oceanic observatory for the vicarious calibration of U. S. satellite ocean color sensors, including

The role of metallurgy in the NIST investigation of the world trade center towers collapse

November 1, 2007
Author(s)
Stephen W. Banovic, Timothy J. Foecke, William E. Luecke, Joseph D. McColskey, Christopher N. McCowan, Thomas A. Siewert, Frank W. Gayle
On August 21, 2002, on the direction of the U.S. Congress, the National Institute of Standards and Technology (NIST) initiated an investigation into the collapse of the World Trade Center (WTC) towers. In support of the overall investigation goals, the

Time for a Better Receiver: Chip-Scale Atomic Frequency References

November 1, 2007
Author(s)
John E. Kitching
Atomic clocks and precision timing are at the core of almost every aspect of global navigation satellite systems (GNSS). A GNSS receiver determines its position with respect to a subset of the constellation of orbiting satellites by measuring the time

Young's Modulus Measurements in Standard IC CMOS Processes using MEMS Test Structures

November 1, 2007
Author(s)
Janet M. Cassard, David L. Herman, Paul T. Vernier, Don DeVoe, Michael Gaitan
This letter presents a method to measure the Young?s moduli of the individual thin film layers in a commercial integrated circuit (IC) foundry process. The method is based on measuring the resonance frequency of an array of micromachined cantilevers and

Development of Ultra-Low Magnetic Field Sensors With Magnetic Tunnel Junctions

October 31, 2007
Author(s)
Philip Pong, John E. Bonevich, William F. Egelhoff Jr.
The discovery of tunneling magnetoresistance (TMR) has enhanced the magnetoresistance (MR) ratio from the giant magnetoresistance (GMR) regime of around 10% to over 400% at room temperature. A combination of magnetic tunnel junctions with high

Investigating Resource Allocation in a Standards-Based Grid Compute Economy

October 31, 2007
Author(s)
Christopher E. Dabrowski
This paper reports work investigating resource allocation in a simulated grid compute economy where consumers and providers employ software components implemented with emerging WS and grid standards. The investigation employs a model to simulate inter

Critical Role of Side-Chain Attachment Density on the Order and Device Performance of Polythiophenes

October 30, 2007
Author(s)
Regis J. Kline, Dean DeLongchamp, Daniel A. Fischer, Eric K. Lin, Lee J. Richter, Michael L. Chabinyc, Martin Heeney, Iain McCulloch
High performance, solution processable semiconductors are critical to the realization of low cost, large area electronics. We show that a signature molecular packing motif - side-chain interdigitation - correlates to high performance for a large and

VAST 2007 Contest - Blue Iguanadon

October 30, 2007
Author(s)
Georges Grinstein, Catherine Plaisant, Theresa O'Connell, Sharon J. Laskowski, Jean Scholtz, Mark Whiting
Visual analytics experts realize that one effective way to push the field forward and to develop metrics for measuring the performance of various visual analytics components is to hold an annual competition. The second Visual Analytics Science and

Compositional Control in Electrodeposited Ni (subscript x) Pt (subscript 1-x) Films

October 29, 2007
Author(s)
J Mallett, Erik B. Svedberg, John E. Bonevich, Alexander J. Shapiro, William F. Egelhoff Jr., Thomas P. Moffat
Electrochemical co-deposition of a series of fcc Ni(subscript x)PT(subscript 1-x) alloys is demonstrated. The alloy composition is a monotonic function of potential. The Pt-rich Ni(subscript x)PT(subscript 1-x) alloys are formed at potentials positive to

Effect of Static Analysis Tools on Software Security: Preliminary Investigation

October 29, 2007
Author(s)
Vadim Okun, William F. Guthrie, Romain Gaucher, Paul E. Black
Static analysis tools can handle large-scale software and find thousands of defects. But do they improve software security? We evaluate the effect of static analysis tool use on software security in open source projects. We measure security by
