SER Performance Analysis for Physical Layer Network Coding over AWGN Channel

December 3, 2009
Author(s)
Yi Qian, Kejie Lu, Shengli Fu, Hsiao-Hwa Chen
While original network coding is proposed over data link layer, recent work suggests that it can also be implemented on physical layer. In fact it is more natural for wireless networks because of its omnidirectional transmission. In this paper, we

Synthetic Magnetic Fields for Ultracold Neutral Atoms

December 3, 2009
Author(s)
Yu-Ju Lin, Robert L. Compton, Karina K. Jimenez Garcia, James V. Porto, Ian B. Spielman
Neutral atomic Bose condensates and degenerate Fermi gases have realized important many-body phenomena in their most simple and essential forms, without many of the complexities usually associated with material systems. A rich source of physics in

Thermal Stability of Confined Flip-Chip Laminated w-Functionalized Monolayers

December 3, 2009
Author(s)
Mariona Coll Bau, Curt A. Richter, Christina A. Hacker
We present the results of an IR study of the effect of temperature on the formation of Au-monolayer-Si molecular junctions by using a flip-chip lamination approach. Carboxylic acid-terminated alkanethiols self-assembled on ultrasmooth gold substrate have

Conservative Confidence Ellipsoids for Linear Model Parameters

December 1, 2009
Author(s)
Andrew L. Rukhin
This paper studies properties of conservative confidence ellipsoids for parameters of a general linear model. These regions are obtained on the basis of a linear estimator when only a vague knowledge of (heterogeneous) error variances is available. The

Determination of Elements in SRM Soil 2709a by Neutron Activation Analysis

December 1, 2009
Author(s)
Rick L. Paul, Elizabeth A. Mackey, Rolf L. Zeisler, Rabia Oflaz, Bryan E. Tomlin
A combination of instrumental neutron activation analysis (INAA) and prompt gamma-ray activation analysis (PGAA) was used to value assign 35 elements in SRM soil 2709a (San Joaquin Soil). INAA with counting of short-lived radioisotopes was used for

Extension of the resonance line series of Mg III

December 1, 2009
Author(s)
C M. Brown, Alexander Kramida, Uri Feldman, Joseph Reader
Spectra of Mg emitted by a Penning discharge were recorded in the extreme ultraviolet (EUV) on a 10.7-m grazing-incidence spectrograph with phosphor image plates. The spectra provided nine new lines of Mg III between 156 and 166 Å and allowed us to improve

From Simulation to Real Robots with Predictable Results: Methods and Examples

December 1, 2009
Author(s)
Stephen B. Balakirsky, Stefano Carpin, George Dimitoglou, Benjamin Balaguer
From a theoretical perspective, one may easily argue (as we will in this chapter) that simulation accelerates the algorithm development cycle. However, in practice many in the robotics development community share the sentiment that "Simula-tion is doomed

From the Editor's Desk: Let's Have Some Fun

December 1, 2009
Author(s)
Catherine A. Remley
This is an Editorial for the December, 2009 issue of IEEE Microwave Magazine. Kate Remley, the Editor-in-Chief, writes about timely topics for the members of the Microwave Theory and Techniques Society (MTT-S).

Gradient Nanofiber Scaffold Libraries for Rapid Screening of Cell-Material Interactions

December 1, 2009
Author(s)
Carl G. Simon Jr., Murugan Ramalingam, Marian F. Young, Vinoy Thomas
Scaffolds play a key role in tissue engineering wherein they provide structural support for cells to adhere, grow and guide them to synthesize tissue. Scaffolds made of multiple biomaterials are typically required to mimic the three-dimensional (3D)

Hyperspectral Imager Characterization and Calibration

December 1, 2009
Author(s)
John T. Woodward IV, Steven W. Brown, Allan W. Smith, Keith R. Lykke
Current radiometric calibration standards, specifically blackbody and lamp-based optical radiation sources, produce spatially, spectrally, and temporally simple scenes. Hyperspectral imaging instruments, which in-practice view spatially, spectrally, and

Interoperable Methodologies and Techniques in CAD

December 1, 2009
Author(s)
Semiha Kiziltas, Fernanda Leite, Burcu Akinci, Robert R. Lipman
It is estimated that the cost of inadequate interoperability in the U.S. capital facilities industry is approximately $15.8 billion per year. Lack of or inadequate interoperability results in data and transfer problems and duplication of business

NIST Reference Material Scaffolds for Tissue Engineering

December 1, 2009
Author(s)
Carl G. Simon Jr.
The National Institute of Standards and Technology (NIST) has deployed Reference Material (RM) scaffolds for tissue engineering: a series of well-characterized 3D tissue scaffolds with differing porosities (RM 8395, RM 8396 and RM 8397) (Fig. 1). Customers

Quantitative Imaging to Assess Tumor Response to Therapy: Common Themes of Measurement, Truth Data & Error Sources

December 1, 2009
Author(s)
Charles D. Fenimore, Charles R. Meyer, Samuel G. Armato, Geoffrey McLennan, Luc Bidaut, Daniel P. Barboriak, Marios A. Gavrielides, Nicholas Petrick, Edward F. Jackson, Michael McNitt-Gray, Paul E. Kinahan, Binsheng Zhao
Rationale and Objectives Early detection of tumor response to therapy is a key goal. Finding measurement algorithms capable of early detection of tumor response could individualize therapy treatment as well as reduce the cost of bringing new drugs to
