Writing Guidelines to Develop an Memorandum of Understanding for Interoperable Automated Fingerprint Identification Systems

May 14, 2013
Author(s)
Susan M. Ballou, Michael Garris, Anthony Clay, Joi Dickerson, Peter T. Higgins, Lisa Jackson, Joe Morrissey, Beth Owens, Joe Polski, Janet Hoin, Leo Norton, Melissa Taylor
This is one of a series of documents prepared by the Latent Print Automated Fingerprint Identification System (AFIS) Interoperability Working Group. The purpose of these documents is to provide guidance and a framework to those involved in the

Differential cavity ring-down spectroscopy

May 9, 2013
Author(s)
Jeremie B. Courtois, Katarzyna E. Bielska, Joseph T. Hodges
We present a technique called differential cavity ring-down spectroscopy (D-CRDS) for reducing etaloning effects in a ring-down spectrometer. The method relies on alternately measuring and then subtracting intra-cavity losses associated with pairwise TEM00

Structure and Stability of SnO2 Nanocrystals and Surface-Bound Water Species

May 8, 2013
Author(s)
Rick L. Paul, Hsiu-Wen Wang, David J. Wesolowski, Thomas E. Proffen, Lucus Vicek, Wei Wang, Lawrence F. Allard, Alexander I. Kolesnikov, Mikhail Feygenson, Lawrence M. Anovitz
The structure of SnO2 nanoparticles (avg. 5 nm diameter) with a few layers of water on the surface has been elucidated by atomic pair distribution function (PDF) methods using in situ neutron total scattering data and molecular dynamics (MD) simulations

This is one of a series of documents prepared by the Latent Print Automated Fingerprint Identification System (AFIS) Interoperability Working Group. The purpose of these documents is to provide guidance and a framework to those involved in the

The Biological Evidence Preservation Handbook: Best Practices for Evidence Handlers

April 23, 2013
Author(s)
Susan M. Ballou, Margaret C. Kline, Mark D. Stolorow, Melissa Taylor, Shannan Williams, Phylis S. Bamberger, Burney Yvette, Larry Brown, Cynthia E. Jones, Ralph Keaton, William Kiley, Karen Thiessen, Gerry LaPorte, Joseph Latta, Linda E. Ledray, Randy Nagy, Linda Schwind, Stephanie Stoiloff, Brian Ostrom
The report of the Technical Working Group on Biological Evidence Preservation offers guidance for individuals involved in the collection, examination, tracking, packaging, storing, and disposition of biological evidence. This may include crime scene

Organosilicate Polymer E-Beam Resists with High Resolution, Sensitivity and Stability

February 28, 2013
Author(s)
Christopher Soles, Richard Kasica, Hae-Jeong Lee, Jae H. Sim, Sung-Il Lee, Ki-Bum Kim, Hyun-Mi Kim, Do Y. Yoon
Hydrogen silsesquioxane (HSQ) is an attractive electron-beam (e-beam) resist for sub-20 nm lithography due to its high resolution, excellent line-edge-roughness (LER), and good plasma etch resistance. However, the sensitivity and long-term stability of HSQ

To Predict Vibrational Spectra, Are Anharmonic Calculations Worthwhile?

January 22, 2013
Author(s)
Ruth L. Jacobsen, Karl K. Irikura, Russell D. Johnson III, Raghu N. Kacker
Anharmonic calculations using vibrational perturbation theory are known to provide near-spectroscopic accuracy when combined with high-level ab initio potential energy functions. However, performance with economical, popular electronic structure methods is
