An Evaluation of Description Logic for the Development of Product Models

November 10, 2008
Author(s)
Xenia Fiorentini, Sudarsan Rachuri, Hyo Won Suh, Jae H. Lee, Ram D. Sriram
The languages and logical formalisms developed by information scientists and logicians concentrate on the theory of languages and logical theorem proving. These languages, when used by domain experts to represent their domain of discourse, most often have

Long-distance entanglement-based quantum key distribution over optical fiber

November 10, 2008
Author(s)
Toshimori Honjo, Sae Woo Nam, Hiroki Takesue, Qiang Zhang, H. Kamada, Y. Nishida, O. Tadanaga, M. Asobe, Burm Baek, Robert Hadfield, Shigehito Miki, Mikio Fujiwara, Masahide Sasaki, Z. Wang, K. Inoue, Yoshihisa Yamamoto
We report the first entanglement-based quantum key distribution (QKD) experiment over a 100-km optical fiber. We used superconducting single photon detectors based on NbN nanowires that provide high-speed single photon detection for the 1.5-υm telecom band

The Infrared Spectroscopy and Photochemistry of NO 3 Trapped in Solid Neon

November 10, 2008
Author(s)
Marilyn E. Jacox, Warren E. Thompson
NO3 can be stabilized in solid neon either by codeposition at 4.3 K of a Ne:O2 mixture with a Ne:NO mixture that had been passed through a microwave discharge or, in higher yield, by codeposition of a Ne:NO mixture with a Ne:O2 mixture, followed by

TREC Genomics Special Issue---Information Retrieval

November 10, 2008
Author(s)
Ellen M. Voorhees, William Hersh
This paper is the introductory paper for a special issue of the journal Information Retrieval devoted to the TREC genomics track. The TREC genomics track ran from 2003 to 2007 and was one of the largest and longest-running challenge evaluations in

Proprietary Design Information and Fruit Pies

November 7, 2008
Author(s)
John A. Horst
The proliferation of proprietary design info exchange formats is causing high costs to manufacturers. The standards solution is offered as both attainable and worth the effort. A design information exchange standards development life-cycle is proposed.

Electronic Structure and Chemistry of Iron-Based Metal Oxide Nanostructured Materials: A NEXAFS Investigation of BiFeO3, Bi2Fe4O9, a-Fe2O3, g-Fe2O3, and Fe/Fe3O4

November 6, 2008
Author(s)
Tae-Jin Park, S Sambasivan, Daniel A. Fischer, R Ramesh, J A. Misewich, S S. Wong
We present a systematic and detailed Near Edge X-ray Absorption Fine Structure (NEXAFS) experimental investigation of the electronic structure and chemistry of iron-based metal oxide nanostructured (FeMONS) materials including BiFeO3, Bi2Fe4O9, a-Fe2O3, ?-

High resolution 17 keV to 75 keV backlighers for high energy density experiments

November 6, 2008
Author(s)
Lawrence T. Hudson, H.S. Parks, B.R. Maddox, E. Giraldez, P. Hatchett, N. Izumi, M.H. Key, S. LePape, A. MacKinnon, A MacPhee, P.K. Patel, T.W. Phillips, B.A. Remington, John F. Seely, A. Tommasini, R. Town, J. Workman
We have developed 17 keV to 75 keV 1-dimensional and 2-dimensional high-resolution (<10 m) radiography using high-intensity short pulse lasers. High energy K- sources are created by fluorescence from hot electrons interacting in the target material after

Avoided crossings between bound states of ultracold Cesium dimers

November 5, 2008
Author(s)
Jeremy M. Hutson, Eite Tiesinga, Paul S. Julienne
We present a new computational method for calculating bound states of ultracold alkali metal dimers in the presence of magnetic fields. The new method is based on propagation of coupled differential equations and does not use a basis set for the

Correlation of Local Structure and Electrical Activation in Arsenic Ultra Shallow Junctions in Silicon

November 5, 2008
Author(s)
D. Giubertoni, Giancarlo Pepponi, Salvatore Gennaro, Massimo Bersani, M A. Sahiner, Stephen P. Kelty, Roisin Doherty, Majeed A. Foad, Max Kah, Karen J. Kirkby, Joseph Woicik
The understanding of the behavior of arsenic in highly doped near surface silicon layers is of crucial importance for the formation of N-type Ultra Shallow Junctions in current and future VLSI technology. This is of peculiar relevance when studying novel

Ontology-based Technologies - Technology Transfer from Bioinformatics?

November 5, 2008
Author(s)
Fabian M. Neuhaus
In the call for paper for OIC 2008 the description of the conference contains the following optimistic outlook: New approaches are required to enable greater flexibility, precision, timeliness and automation of analysis in response to rapidly evolving

Overview of the TREC 2006 Question Answering Track

November 5, 2008
Author(s)
Hoa T. Dang, Jimmy Lin, Diane Kelly
The TREC 2006 question answering track contained two tasks: a main task and a complex, interactive question answering (ciQA) task. As in 2005, the main task consisted of series of factoid, list, and ``Other'' questions organized around a set of targets

User's Guide for the Quality of Design Testing Tool and the Content Checker

Katherine C. Morris, Simon P. Frechette, Puja Goyal, Joshua Lubell, Boonserm Kulvatunyou, Salifou Sidi Malick, Nicolas Brayard, Severin Tixier
This document describes the operation and usage of the Quality of Design and the Content Checker Testing Tools. These tools were developed at the National Institute of Standards and Technology (NIST) to support people in developing standards for the

Calibration of a Computer Assisted Orthopedic Hip Surgery Phantom

November 4, 2008
Author(s)
Daniel S. Sawyer, Nicholas G. Dagalakis, Craig M. Shakarji, Yong Sik Kim
Orthopedic surgeons have identified a need for calibration artifacts (phantoms) to establish the traceability (to the SI unit of length) of measurements performed with Computer Assisted Orthopedic Surgery (CAOS) systems. These phantoms must be lightweight

HF RFID Electromagnetic Emissions and Performance

November 4, 2008
Author(s)
David R. Novotny, Jeffrey R. Guerrieri, Michael H. Francis, Catherine A. Remley
We examined the emissions, and susceptibility of commercial High-Frequency Radio Frequency Identification (HF proximity RFID) systems to interrupt and eavesdropping. RFID systems are being used in an increasing number of financial, identification, and
