Maximum Likelihood Estimation for an Observation Driven Model for Poisson Counts

January 28, 2005
Author(s)
Richard D. Davis, William T. Dunsmuir, Sarah B. Streett
This paper is concerned with an observation driven model for time series of counts whose conditional distribution given past observations follows a Poisson distribution. This class of models is capable of modeling a wide range of dependence structures and

Microwave transitions and nonlinear magneto-optical rotation in anti-relaxation-coated cells

January 27, 2005
Author(s)
D Budker, Leo W. Hollberg, Derek F. Kimball, John E. Kitching, S Pustelny, V V. Yashchuk
Using laser optical pumping, widths and frequency shifts are determined for microwave transitions between ground-state hyperfine components of {8s}Rb and d{87}Rb atoms contained in vapor cells with alkane anti-relaxation coatings. The results are compared

Single Molecule Fluorescence Resonance Energy Transfer of a RNA Kissing Complex

January 27, 2005
Author(s)
Peter Yim, Xiaoyi Y. Zhang, E S. DeJong, J M. Carroll, John P. Marino, Lori S. Goldner
We used single molecular fluorescence resonance energy transfer (FRET) to understand the conformation of a RNA loop to loop complex, termed a kissing complex. The kissing complex formed by two Escherichia Coli (ColE1) plasmid-encoded transcripts, RNA I and

Diffraction Effects in Radiometry

January 26, 2005
Author(s)
Eric L. Shirley
This is the draft submitted to be Chapter 10 of the book, Modern Radiometric Practice, edited by Albert C. Parr, Raju U. Datla, and James W. Gardner. This chapter is intended to discussion issues of diffraction effects on radiometric measurements.

Appendix A; Example: Calibration of a Cryogenic Blackbody

January 22, 2005
Author(s)
Raju V. Datla, Eric L. Shirley, Albert C. Parr
This manuscript is intended to be an Appendix in a book on radiometry, The Practice of Optical Radiometry. The Appendix is to provide a real example of a blackbody calibration, in order to demonstrate the statistical analysis of data. The role of

Carbon multi-walled nanotubes grown by HWCVD on a pyroelectric detector

January 21, 2005
Author(s)
John H. Lehman, Rohit Deshpande, Paul Rice, Bobby To, Anne Dillon
Carbon multi-wall nanotubes (MWNTs) were grown on a lithium niobate (LiNbO3) pyroelectric detector with a nickel film as the catalyst by hot-wire chemical vapor deposition (HWCVD). Two detectors are documented, each with slightly different deposition

Rapid heating of a strongly coupled plasma at the solid-liquid phase transition

January 21, 2005
Author(s)
M J. Jensen, T Hasegawa, John Bollinger, Daniel H. Dubin
Between 10 4 and 10u6 A9Be^+ ions were trapped in a Penning trap and laser-cooled to siml K, where they formed a crystalline plasma. We measured the ion temperature as a function of time after turning off the laser-cooling and observed a rapid temperature

Generation of Lattice Wannier Functions via Maximum Localization

January 20, 2005
Author(s)
Eric J. Cockayne
A method is presented for generating approximate lattice Wannier functions (LWF) for lattice dynamics problems, using the dynamical matrix for a supercell as input. The lattice Wannier functions fit selected phonon frequencies and eigenvectors exactly, are

Design, Development and Testing of a Hybrid Device for In-Situ Testing of Sealant

January 19, 2005
Author(s)
Christopher C. White, E Embree, C Buch
A new hybrid in-situ sealant-testing device that uses movement to both characterize and fatigue standard ASTM C719 sealant samples is described. This five sample device, records the force-response data for every deformation cycle of every sample. From this

Uncertainty reporting for experimental thermodynamic properties

January 13, 2005
Author(s)
Qian Dong, Robert D. Chirico, Xinjian Yan, X Hong, Michael D. Frenkel
This paper reviews practices in the expression of uncertainty in the experimental literature for thermodynamic property measurements with determinations of critical temperature for pure compounds used as a case study. The time period considered is from
