Morphological origins of polarization-induced scattering anisotropy from organic thin films

January 14, 2016
Author(s)
Eliot Gann, Brian A. Collins, Maolong Tang, John R. Tumbleston, Subhrangsu Mukherjee, Harald W. Ade
Anisotropic scattering patterns have been observed from organic thin films that are isotropic on the scale of the probe in polarized resonant X-ray scattering experiments. The symmetry is broken by local correlations between molecular orientation and

Polymer Glass-Formation in Variable Dimension

January 14, 2016
Author(s)
Jack F. Douglas, Freed Karl, Wensheng Xu
We explore the nature of glass-formation in variable spatial dimensionality (d) based on the generalized entropy theory, a synthesis of the Adam-Gibbs model with direct computation of the configurational entropy of polymer fluids using an established

Survival analysis approach to account for non-exponential decay rate effects in lifetime experiments

January 13, 2016
Author(s)
Kevin J. Coakley, Maynard S. Dewey, Michael G. Huber, Hans P. Mumm, Alan Keith Thompson, Andrew T. Yue, C. R. Huffer, P. R. Huffman, C. M. O'Shaughnessy, K. W. Schelhammer, D. E. Marley
In experiments that measure the lifetime of trapped particles, in addition to loss mechanisms with exponential survival probability functions, particles can be lost by mechanisms with non-exponential survival probability functions. Failure to account for

FIRE-STRUCTURE INTERACTION EXPERIMENT PLAN FOR FULL-SCALE COMPOSITE FLOOR SYSTEM

January 12, 2016
Author(s)
Lisa Y. Choe, John L. Gross, William L. Grosshandler, Matthew F. Bundy
The newly-constructed National Fire Research Laboratory (NFRL) at the National Institute of Standards and Technology (NIST) provides an opportunity for the structural fire research community to undertake experimental research here-to-for not possible. This

Logic circuit prototypes for three-terminal magnetic tunnel junctions with mobile domain walls

January 12, 2016
Author(s)
Jean Anne Currivan-Incorvia, S. Siddiqui, S. Dutta, Eric R. Evarts, J. Zhang, D. Bono, C A. Ross, M. A. Baldo
Spintronic computing promises superior energy efficiency and nonvolatility compared to conventional field-effect transistor logic. But, it has proven difficult to realize spintronic circuits with a versatile, scalable device design that is adaptable to

Yang-Baxter operators need quantum entanglement to distinguish knots

January 12, 2016
Author(s)
Stephen P. Jordan, Gorjan Alagic, Michael Jarret
Solutions to the Yang-Baxter equation yield representations of braid groups. Under certain conditions, identified by Turaev, traces of these representations yield link invariants. The matrices satisfying the Yang-Baxter equation, if unitary, can be

Background Radiation Measurements at High Power Research Reactors

January 11, 2016
Author(s)
Hans P. Mumm
Research reactors typically host a wide range of activities that make use of the intense neutron fluxes generated at these facilities. Recent interest in performing measurements with relatively low event rates, e.g. reactor antineutrino detection, at these
