Spectral Line-by-Line Pulse Shaping of On-Chip Microresonator Frequency Combs

December 1, 2011
Author(s)
Fahmida Ferdous, Houxun H. Miao, Daniel E. Leaird, Kartik Srinivasan, Jian Wang, Lei Chen, Leo T. Varghese, Andrew M. Weiner
We report, for the first time to the best of our knowledge, spectral phase characterization and line-by-line pulse shaping of an optical frequency comb generated by nonlinear wave mixing in a micro-ring resonator. The comb is compressed to a train of near

The New SI: The Role of CODATA

December 1, 2011
Author(s)
David B. Newell, Peter J. Mohr, Barry N. Taylor
The mission of the International Council for Science : Committee on Data for Science and Technology (CODATA ) is to strengthen international science for the benefit of society by promoting improved scientific and technical data management and use. One of

Development and Certification of Green Tea-Containing Standard Reference Materials

November 30, 2011
Author(s)
Lane C. Sander, Mary Bedner, Michael C. Tims, James H. Yen, David L. Duewer, Barbara J. Porter, Steven J. Christopher, Russell D. Day, Stephen E. Long, John L. Molloy, Karen E. Murphy, Brian E. Lang, Rachel A. Lieberman, Laura J. Wood, M. Payne, M. C. Roman, J. M. Betz, A. NguyenPho, Katherine E. Sharpless, Stephen A. Wise
A suite of three green tea-containing Standard Reference Materials (SRMs) has been issued by the National Institute of Standards and Technology (NIST). The materials are characterized for catechins, xanthine alkaloids, theanine, and toxic elements. As many

Dimensional Evolution of Spin Correlations in the Magnetic Pyrochlore Yb 2 Ti 2 O 7

November 30, 2011
Author(s)
K. A. Ross, L. R. Yaraskavitch, M. Laver, Jason S. Gardner, J. A. Quilliam, S. Meng, J. B. Kycia, Deepak Singh, Th. Proffen, H. A. Dabkowska, B. D. Gaulin
The pyrochlore material Yb 2Ti 2O 7 displays unexpected quasi-two-dimensional (2D) magnetic correlations within a cubic lattice environment at low temperatures, before entering an exotic disordered ground state below T=265mK. We report neutron scattering

High-temperature tensile constitutive data and models for structural steels in fire

November 30, 2011
Author(s)
William E. Luecke, Stephen W. Banovic, Joseph D. McColskey
This report documents the stress-strain behavior of a collection of structural steels recovered from the collapse of the World Trade Center. These steels, combined with literature data form the basis of a model for the stress-strain behavior of structural

QCMA with One-sided Error Equals QCMA with Two-sided Error

November 30, 2011
Author(s)
Stephen P. Jordan, Daniel Nagaj
QCMA is the set of decision problems such that if the answer is yes, there exists a classical bitstring, or proof, that can be efficiently verified by a quantum computer. The verifier is allowed a small probability of rejecting a valid proof or accepting
