Conversion of laser optical rotation noise in cesium vapor

Author(s)
Ricardo Jimenez Martinez, Svenja A. Knappe, William C. Griffith, John E. Kitching
We have studied the noise in the optical rotation of a linearly polarized laser beam transmitted through a spin-polarized 133Cs vapor as a function of its...

Factors that Influence Algorithm Performance

Author(s)
P J. Phillips, J. R. Beveridge, Geof H. Givens, Bruce A. Draper
A statistical study is presented quantifying the effects of covariates such as gender, age, expression, image resolution and focus on three face recognition...

Lattice Interferometer for Ultra-Cold Atoms

Author(s)
Mikkel Andersen, Tycho Sleator
We demonstrate an atomic interferometer based on ultra-cold atoms released from an optical lattice. This technique yields a large improvement in signal to noise...

Combinatorial Software Testing

Author(s)
David R. Kuhn, Raghu N. Kacker, Yu Lei, Justin Hunter
Developers of large data-intensive software often notice an interesting - though not surprising - phenomenon: when usage of an application jumps dramatically...

A Spin-1/2 Optical Lattice Clock

Author(s)
Nathan D. Lemke, Andrew D. Ludlow, Zeb Barber, Tara M. Fortier, Scott A. Diddams, Yanyi Jiang, Steven R. Jefferts, Thomas P. Heavner, Thomas E. Parker, Christopher W. Oates
We experimentally investigate an optical clock based on 171Yb (I = 1/2) atoms confined in an optical lattice. We have evaluated all known frequency shifts to...

Development of a Seebeck Coefficient Standard Reference Material

Author(s)
Nathan Lowhorn, Winnie Wong-Ng, John Lu, Evan L. Thomas, Makoto Otani, Martin L. Green, Neil Dilley, Jeffrey Sharp, Thanh N. Tran
We have successfully developed a Seebeck coefficient Standard Reference Material (SRM ), Bi2Te3, that is crucial for interlaboratory data comparison and for...

Volatility of Aprotic Ionic Liquids - A Review

Author(s)
Jose M.S.S. Esperanca, Jose N. Canongia Lopes, Mohd Tariq, Luis M.N.B.F. Santos, Joe W. Magee, Luis P. Rebelo
A review of research on the volatility of aprotic ionic liquids is presented. This topic is limited to aprotic liquids, since measurements have led to a...

The Fifth Industrial Fluid Properties Simulation Challenge

Author(s)
F Case, Anne M. Chaka, J Moore, Raymond D. Mountain, J Olson, Richard B. Ross, Martin Schiller, Vincent K. Shen, Eric A. Stahlberg
The fifth industrial fluid properties simulation challenge was held in 2008. In it the contestants were challenged to predict specific, industrially relevant...

Cell Interactions with Biomaterials Gradients and Arrays

Author(s)
Yanyin Yang, Vinoy Thomas, Abby W. Morgan, Shauna M. Dorsey, Carl Simon Jr.
Gradients and arrays have become very useful to the fields of tissue engineering and biomaterials.  Both gradients and arrays make efficient platforms for...

Effects of Polymorphism on Charge Transport in Organic Semiconductors

Author(s)
Oana Jurchescu, M. Devin, Sankar Subramanian, Sean R. Parkin, Brandon Vogel, John E. Anthony, Thomas Jackson, David J. Gundlach
The increasing interest in fluorinated 5,11-bis(triethylsilylethynyl)anthradithiophene (diF TES ADT) is motivated by the demonstrated high performance field...
