October 25, 2004
Author(s)
Ellen M. Voorhees, Donna K. Harman
This chapter provides an executive summary of the TREC workshop series and the remainder of thevolume. It explains the motivation for TREC and highlights TREC's accomplishments in improving retrievaleffectiveness and fostering technology transfer.

Observation of Quantum Oscillations between a Josephson Phase Qubit and a Microscopic Resonator using Fast Readout

October 25, 2004
Author(s)
Ken Cooper, Matthias Steffen, Robert McDermott, Raymond Simmonds, Seongshik Oh, Dustin Hite, David P. Pappas, John M. Martinis
We have detected coherent quantum oscillations between Josephson phase qubits and microscopic critical current fluctuators by implementing a new state readout technique that is an order of magnitude faster than previous methods. The period of the

Mechanism of Dynamic NBTI of pMOSFETs

October 21, 2004
Author(s)
Baozhong Zhu, John S. Suehle, Joseph B. Berstein
A series of experiments are conducted to study the physical mechanism of reduced NBTI effects observed under pulsed bias conditions. A reduction of Vth and Ion is observed for pulse periods shorter than critical time constants that are believed to be

Dynamic behavior of dagger-shaped atomic force microscope cantilevers

October 20, 2004
Author(s)
K Shen, Donna C. Hurley, J Turner
Experimental techniques based on the atomic force microscope (AFM) have been developed for characterizing mechanical properties at the nanoscale and applied to a variety of materials and structures. Atomic force acoustic microscopy (AFAM) is one such

Validation of the Receprocity Law for Coating Photodegradation

October 20, 2004
Author(s)
Joannie W. Chin, Tinh Nguyen, Jonathan W. Martin, E Byrd
Accelerating the photodegradation of commerical polymeric materials has great practical importance in the weathering community. However, questions exist as to whether high radiant flux exposure results cn be extrapolated to in-service exposure levels
