Resource Letter SS-1: The Spin-Statistics Connection

April 4, 2012
Author(s)
Catalina Curceanu, John D. Gillaspy, R. C. Hilborn
This Resource Letter provides a guide to the literature on the Spin-Statistics Connection and related issues such as the Pauli Exclusion Principle and particle indistinguishability. Journal articles and books are cited for the following topics: basic

Scatterfield Microscopy of 22 nm Node Patterned Defects using Visible and DUV Light

April 4, 2012
Author(s)
Bryan M. Barnes, Martin Y. Sohn, Francois R. Goasmat, Hui Zhou, Richard M. Silver, Abraham Arceo
Smaller patterning dimensions and novel architectures are fostering research into improved methods of defect detection in semiconductor device manufacturing. This initial experimental study, augmented with simulation, evaluates scatterfield microscopy to

Technical Note on Unexpected Bias in NIST 4p Ionization Chamber Measurements

April 4, 2012
Author(s)
Michael P. Unterweger, Ryan P. Fitzgerald
The NIST 4π pressurized ionization chamber “A” (PIC “A”) has been the mainstay for secondary calibrations of liquid and gaseous gamma-ray emitting sources for the last 40-45 years. It has also been the main instrument used to measure the half-lives of

IREX III - Performance of Iris Identification Algorithms

April 3, 2012
Author(s)
Patrick J. Grother, George W. Quinn, James R. Matey, Mei L. Ngan, Wayne J. Salamon, Gregory P. Fiumara, Craig I. Watson
Iris recognition has long been held as an accurate and fast biometric. In the first public evaluation of one-to-many iris identification technologies, this third activity in the Iris Exchange (IREX) program has measured the core algorithmic efficacy and

Performance of Steel Moment Connections under a Column Removal Scenario. I: Experiments

April 3, 2012
Author(s)
Hai S. Lew, Joseph A. Main, Stephen D. Robert, Fahim Sadek, Vincent Chiarito
This paper presents an experimental study of two full-scale steel beam-column assemblies, each comprising three columns and two beams, to (1) define their response characteristics under a column removal scenario, including the capacity of the beams and

Performance of Steel Moment Connections under a Column Removal Scenario. II: Analysis

April 3, 2012
Author(s)
Fahim H. Sadek, Joseph Main, Hai S. Lew, Sherif El-Tawil
This paper presents a computational investigation of the response of steel beam-column assemblies with moment connections under monotonic loading conditions simulating a column removal scenario. Two beam-column assemblies are analyzed, which incorporate (1

Basing Cybersecurity Training on User Perceptions

April 2, 2012
Author(s)
Susanne M. Furman, Mary F. Theofanos, Yee-Yin Choong, Brian C. Stanton
The National Initiative for Cybersecurity Education (NICE) will be conducting a nationwide awareness and outreach program to effect behavioral change. To be effective, an educational campaign must first understand users’ perceptions of computer and online

Dielectrophoretic Cell Capture on Polyester Membranes

April 2, 2012
Author(s)
Conni Hanke, Petra S. Dittrich, Darwin Reyes-Hernandez
A new system for dielectrophoretic cell capture on porous polyester (PET) membranes is presented. Conventional photolithographic techniques were used to fabricate gold microelectrodes on a PET membrane. We characterized these electrodes to proof that there
