Enhanced Mass Transport in Ultra-Rapidly-Heated Ni/Si Thin-Film Multilayers

November 15, 2009
Author(s)
Lawrence P. Cook, Richard E. Cavicchi, Nabil Bassim, Susie Eustis, Winnie Wong-Ng, Igor Levin, Ursula R. Kattner, Carelyn E. Campbell, Christopher B. Montgomery, William F. Egelhoff Jr., Mark D. Vaudin
We have investigated multilayer and bilayer Ni/Si thin films by nano-differential scanning calorimetry (DSC) at ultra rapid scan rates, in a temperature-time regime not accessible with conventional apparatus. DSC experiments were completed at slower scan

Fabrication with Flip-Chip Lamination

November 15, 2009
Author(s)
Mariona Coll Bau, Curt A. Richter, Christina Hacker
Fabrication with Flip-Chip Lamination , Mariona Coll, DR Hines, CA Richter, CA Hacker, Nanotechnology colloquium, Wake Forest University, 11-09.

Quasi-phasematched Second Harmonic Generation in GaAs Microdisks

November 15, 2009
Author(s)
Paulina S. Kuo, W Fang, Glenn S. Solomon
We discuss design and tuning of second-harmonic generation in GaAs microdisks. Quasi-phasematching can be achieved in the microdisk geometry without external domain inversions, but efficient nonlinear optical mixing requires that all waves be resonant

Realization of a programmable two-qubit quantum processor

November 15, 2009
Author(s)
David Hanneke, Jonathan Home, John D. Jost, Jason Amini, Dietrich G. Leibfried, David J. Wineland
The universal quantum computer is a device that could simulate any physical system and represents a major goal for the field of quantum information science. Algorithms performed on such a device are predicted to offer significant gains for some important

Sundararajan, Elena Timofeeva, Todd Tritcak, A.N. Turanov, Stefan Van Vaerenbergh, Dongsheng Wen, Sanjeeva Witharana, Charles Chun Yang, W.-H. Yeh, Xiao-Zheng Zhao, Sheng-Qi Zhou
This article reports on the International Nanofluid Property Benchmark Exercise (INPBE) in which the thermal conductivity of identical samples of colloidal dispersions of nanoparticles, or nanofluids , was measured by over 30 organizations worldwide, using

Density and Speed of Sound Measurements of 1- and 2-Butanol

November 12, 2009
Author(s)
Stephanie L. Outcalt, Arno R. Laesecke, Tara J. Fortin
The density and speed of sound of 1- and 2-butanol have been measured using two instruments. Both instruments use the vibrating-tube method for measuring density. Ambient pressure (83 kPa) density and speed of sound measurements were carried out from 278

Lysozyme Protein Solution with an Intermediate Range Order Structure

November 10, 2009
Author(s)
Yun Liu, Lionel Porcar, Jinhong Chen, Wei-Ren Chen, Peter Falus, Antonio Faraone, Emiliano Fratini, Piero Baglioni
The formation of equilibrium clusters has been studied in both prototypical colloidal system and protein solution. The appearance of a low-Q correlation peak in small angle scattering patterns of lysozyme solution was attributed to the cluster-cluster

An Enabler for Supplier Discovery in Virtual Supply Chains: A Shared Terminology

November 5, 2009
Author(s)
Steven J. Fenves, Eswaran Subrahmanian, Mahesh Mani, Albert T. Jones
Rigid supply-chain organizational structures are giving way to highly dynamic collaborative partnerships. These partnerships will develop rapidly by composing global manufacturing resources in response to open market opportunities; and, they will disband

Development of secondary standards for radium-223

November 5, 2009
Author(s)
Denis E. Bergeron, Brian E. Zimmerman, Jeffrey T. Cessna
223Ra is a bone-seeking alpha emitter, and as such is currently being evaluated as a radiopharmaceutical for the treatment of skeletal metastases. In the clinical setting, dosage measurements are typically achieved with reentrant ionization chambers

A DATA FLOW IMPLEMENTATION OF AGENT-BASED DISTRIBUTED GRAPH SEARCH

November 4, 2009
Author(s)
Imad Hamchi, Mathieu Hoarau, Antoine Fillinger, Nicolas Crouzier, Lukas Diduch, Martial Michel, Vincent M. Stanford
Biological ants organize themselves into forager groups that converge to shortest paths to and from food sources. This has motivated development a large class of biologically inspired agent-based graph search techniques, called Ant Colony Optimization, to

Mass transfer in two-phase microchannel flows

November 4, 2009
Author(s)
Jeffrey D. Martin, Steven D. Hudson
Drop-based microfluidic devices are becoming more common and molecular mass transfer and drop circulation are issues that affect the performance of such devices. Moreover, interfacial properties and surfactant mass transfer rates govern emulsion behavior

Nonlinear calibration of polarimetric radar cross section systems

November 4, 2009
Author(s)
Lorant A. Muth
Polarimetric radar cross section systems are characterized by polarimetric system parameters $\epsilon_h$ and $\epsilon_v$. These parameters can be obtained with the use of rotating dihedrals. The full polarimetric dataset as a function of the angle of

Optical frequency stabilization of a 10 GHz Ti:sapphire frequency comb by saturated absorption spectroscopy in 87Rubidium

November 4, 2009
Author(s)
Dirk Heinecke, Albrecht Bartels, Tara M. Fortier, Danielle Braje, Leo Hollberg, Scott A. Diddams
The high power per mode of a recently-developed 10 GHz femtosecond Ti:sapphire frequency comb permits nonlinear Doppler-free saturation spectroscopy in 87Rubidium with a single mode of the comb. We use this access to the natural linewidth of the Rubidium

Herding, Second Preimage, and Trojan Message Attacks Beyond Merkle-Damgaard

November 3, 2009
Author(s)
Elena Andreeva, Charles Bouillaguet , Orr Dunkelman, John M. Kelsey
In this paper we present new attack techniques to analyze the structure of hash functions that are not based on the classical Merkle-Damgaard construction. We extend the herding attack to concatenated hashes, and to certain hash functions that process each

Radiofrequency dressing of multiple Feshbach resonances

November 3, 2009
Author(s)
A M. Kaufman, R P. Anderson, Thomas Hanna, Eite Tiesinga, Paul S. Julienne, D S. Hall
We demonstrate and explain the coupling of several proximate Feshbach resonances in $^87}$Rb using radiofrequency (rf) radiation. We present accurate measurements of the resonances and observe the changes in the scattering properties that arise through the
