Testing Interoperability Standards - A Test Case Generation Methodology

June 16, 2010
Author(s)
Nenad Ivezic, Jungyub Woo
Over many years, National Institute of Standards and Technology (NIST) built test beds to support interoperability standards development and their implementation within software applications. A general test framework has been proposed to enhance new test

Tooth chipping can reveal bite forces and diets of fossil hominins

June 16, 2010
Author(s)
Paul Constantino, James J. Lee, H Chai, Bernhard Zipfel, Charles Ziscovici, Brian R. Lawn, Peter Lucas
Fossil hominin tooth enamel often exhibits antemortem edge chipping (Robinson 1954; Tobias 1967; Wallace 1973). Here we apply a simple fracture equation to estimate peak bite forces from the sizes of such chips. This equation, previously validated by

Cd-doping effects in Ce 2 MIn 8 (M=Rh and Ir) Heavy Fermion Compounds

June 15, 2010
Author(s)
C. Adriano, C. Giles, E. M. Bittar, L. N. Coelho, F. de Bergevin, C. Mazzoli, L. Paolasini, William Ratcliff, Richard Bindel, Jeffrey Lynn, Z. Fisk, P. G. Pagliuso
Low temperature magnetic properties of Cd-doped Ce 2MIn 8 (M = Rh and Ir) single crystals are investigated. Experiments of temperature dependent magnetic susceptibility, heat capacity and electrical resistivity measurements revealed that Cd-doping enhances

Controlling High Coercivities of Ferromagnetic Nanowires Encapsulated in Carbon Nanotubes

June 15, 2010
Author(s)
Robert D. Shull, Cindi L. Dennis, A. Morelos-Gomez, Florentino N. Lopez-Urias, Emilio N. Munoz-Sandoval, H. Terrones, M. Terrones
Cylindrical ferromagnetic nanowires encapsulated inside multiwalled carbon nanotubes (MWNTs) are synthesized by pyrolizing either ferrocene powder or ferrocene-toluene mixtures. By changing the way the precursor is thermolyzed, we have been able to control

Partitioning of Persistent Organic Pollutants (POPs) between Blubber and Blood of Wild Bottlenose Dolphins: Implications for Biomonitoring and Health

June 15, 2010
Author(s)
Jennifer Yordy, John R. Kucklick, Randall S. Wells, Brian C. Balmer, Lori Schwacke, Teresa Rowles
Biomonitoring of wild cetaceans for persistent organic pollutants (POPs) is heavily reliant on concentrations determined in blubber, and there are few data relating blubber concentrations and levels in blood. Matched blubber and plasma samples (n=56) were

Remembering Paul Garabedian

June 15, 2010
Author(s)
Geoffrey B. McFadden
Paul R. Garabedian, a leader in the field of computational science, passed away on May 13th, 2010, at his home in Manhattan at the age of 82 after a long battle with cancer. During the course of sixty years of research on the faculties at Stanford and New

Role of Nanoparticles in Life Cycle of Nanocomposites

June 15, 2010
Author(s)
Xiaohong Gu, Guodong Chen, Minhua Zhao, Stephanie S. Watson, Paul E. Stutzman, Tinh Nguyen, Joannie W. Chin, Jonathan W. Martin
The objective of this study is to investigate the role of ZnO nanoparticles in the life cycle of a waterborne polyurethane (PU) nanocomposite during UV exposure. The effects of loadings and sizes of ZnO nanoparticles on photodegradation of ZnO/PU films

Sensitivity scaling of dual frequency comb spectroscopy

June 15, 2010
Author(s)
Ian R. Coddington, William C. Swann, Nathan R. Newbury
Coherent dual comb spectroscopy can harness many inherent strengths of frequency combs to provide high-resolution, high-accuracy measurements of a sample response (in both magnitude and phase) on a single detector. We will discuss the noise scaling

Shape comparison between 0.4 ym to 2.0 ym and 20 ym to 60 ym cement particles

June 15, 2010
Author(s)
L Holzer, R Flatt, S.T. Erodgan, Jeffrey W. Bullard, Edward Garboczi
Portland cement powder has a wide particle size distribution, from approximately 0.1 υm to 60 υm. This wide powder size distribution arises via the grinding of much larger clinker particles in fact, several percent of the world s energy expenditures are

Statistical Modeling of Harvestable Kinetic Energy for Wearable Medical Sensors

June 15, 2010
Author(s)
Nathalie Yarkony, Kamran Sayrafian, Antonio Possolo
Energy Harvesting (EH) refers to the process of capturing and storing energy from external sources or ambient environment. Kinetic energy harvested from the human body motion seems to be one of the most convenient and attractive solution for wearable

Test Collection Diagnosis and Treatment

June 15, 2010
Author(s)
Ian M. Soboroff
Test collections are a mainstay of information retrieval research. Since the 1990s, large reusable test collections have been developed in the context of community evaluations such as TREC, NTCIR, CLEF, and INEX. Recently, advances in pooling practice as
