Strain Relaxation in Patterned Strained Silicon Directly on Insulator Structures

December 19, 2005
Author(s)
R Z. Lei, W Tsai, I Aberg, T B. O'Reilly, J L. Hoyt, D A. Antoniadis, H I. Smith, Albert J. Paul, Martin L. Green, J Li, R Hull
Strain relaxation is studied in Strained Silicon Directly on Insulator (SSDOI) substrates patterned with nano-scale features. Using interference lithography, biaxially-strained SSDOI substrates with 30 nm-thick strained Si on insulator films were patterned

The Role of Semantic Roles in Disambiguating Verb Senses

December 19, 2005
Author(s)
Hoa T. Dang, Martha S. Palmer
We describe an automatic Word Sense Disambiguation (WSD) system that disambiguates verb senses using syntactic and semantic features that encode information about predicate arguments and semantic classes. Our system performs better than the best published

Construction Object Identification from LADAR Scans: An Experimental Study Using I-Beams

December 15, 2005
Author(s)
David E. Gilsinn, Geraldine S. Cheok, Christoph J. Witzgall, Alan M. Lytle
Laser Scanning devices (LADAR for Laser Detection and Ranging) are used in construction projects to capture as-built data. They can rapidly generate large unstructured point clouds. This study describes an experiment in which an I-beam on a concrete floor

Efficient generation of correlated photon pairs in a microstructure fiber

December 15, 2005
Author(s)
Jingyun Fan, Alan L. Migdall, L Wang
We report efficient generation of correlated photon pairs through degenerate four-wave mixing in a microstructure fiber. With 735.7 nm pump pulses producing correlated signal (688.5 nm) and idler (789.8 nm) photons in a 1.8 m microstructure fiber, we

Efficient Generation of Correlated Photon Pairs in a Microstructure Fiber

December 15, 2005
Author(s)
Jingyun Fan, Alan L. Migdall, L Wang
We report efficient generation of correlated photon pairs through degenerate four-wave mixing in microstructure fibers. With 735.7 nm pump pulses producing conjugate signal (688.5 nm) and idler (789.8 nm) photons in an 1.8 m microstructure fiber, we detect

Spin Transport for Spin Diffusion Lengths Comparable to Mean Free Paths

December 15, 2005
Author(s)
David R. Penn, Mark D. Stiles
In perpendicular-transport structures with magnetic and non-magnetic layers, there is a resistance associated with changes in the value of current polarization throughout the structure. Starting from a Boltzmann equation Valet and Fert derived macroscopic

The History of Instrumented Impact Testing

December 15, 2005
Author(s)
M. P. Manahan, Thomas A. Siewert
Pendulum impact testing is widely known to have a history that extends back to the turn of the last century. To many researchers today, instrumentation of the impact test to acquire a load-time history, and thereby provide important data in addition to

Self-Oscillating Rubidium Magnetometer using Nonlinear Magneto-Optical Rotation

December 14, 2005
Author(s)
P Schwindt, Leo W. Hollberg, John E. Kitching
The detection of nonlinear magneto-optical rotation (NMOR) of polarized light through alkali atomic vapor is a highly sensitive technique for measuring magnetic fields. We demonstrate that when using frequency modulated light to excite the NMOR resonance

Assessment of Resolution and Dynamic Range for Digital Cinema

December 12, 2005
Author(s)
Charles D. Fenimore, A I. Nikolaev
The proponents of digital cinema seek picture quality exceeding that of the best film-based presentation. Quantifying the performance of systems for the presentation of high quality imagery presents several challenges. One is the dynamic range and the

CSS1 Test Suite

December 12, 2005
Author(s)
Frederick E. Boland Jr.
The goal of this document is to help W3C editors write better specifications, by making a specification easier to interpret without ambiguity and clearer as to what is required in order to conform. It focuses on how to define and specify conformance. It

HL7 Experimental Registry

December 12, 2005
Author(s)
William J. Majurski, A Mccaffrey, Mary T. Laamanen
Our results extending Kuhn's fault class hierarchy provide a justification for the focus of fault-based testing strategies on detecting particular faults and ignoring others. We develop a novel analytical technique that allows us to elegantly prove that

Protecting Digital Evidence from Modification

December 12, 2005
Author(s)
James R. Lyle
Our results extending Kuhn's fault class hierarchy provide a justification for the focus of fault-based testing strategies on detecting particular faults and ignoring others. We develop a novel analytical technique that allows us to elegantly prove that

Wavelength References for Interferometry in Air

December 12, 2005
Author(s)
Richard W. Fox, Brian R. Washburn, Nathan R. Newbury, Leo W. Hollberg
Interferometer sources with multiple known wavelengths can be provided by tunable lasers and calibrated optical reference cavities. The mode wavelengths are known by measuring a laser¿s frequency while locked to the mode in vacuum during a calibration step

Repair of Formamidopyrimidines in DNA Involves Different Glycosylases - Role of the OGG1, NTH1, and NEIL1 Enzymes

December 9, 2005
Author(s)
J Hu, N de Souza-Pinto, K Haraguchi, Barbara A. Hogue, Pawel Jaruga, M M. Greenberg, Miral M. Dizdar, V. Bohr
2,6-diamino-4-hydroxy-5-formamidopyrimidine (FapyG) and 4,6-diamino-5-formamidopyrimidine (FapyA), are formed abundantly in DNA of cultured cells or tissues exposed to ionizing radiation or to other free radical-generating systems. We show here that FapyG
