Emerging Topics: MEMS Atomic Clocks

November 1, 2007
Author(s)
Svenja A. Knappe
The combination of MEMS fabrication with atomic clocks has enabled a new generation of small, cheap, low-power devices. Since the proposal of chip-scale atomic clocks (CSACs) in 2002, the fields of MEMS-based atomic sensors and coherent population trapping

Full Ensemble and Bench Scale Testing of Fire Fighter Protective Clothing

November 1, 2007
Author(s)
D W. Stroup, R A. McLAne
The Thermal Protective Performance (TPP) test was developed to quantify the performance of fire fighter protective clothing ensembles under an intense thermal exposure. This test method has certainly helped to improve the thermal protection of fire fighter

Large-scale MCHF Calculation of the Li I 4d-4f Energy Separation

November 1, 2007
Author(s)
Yuri Ralchenko, Charlotte Fischer
The calculational methods in atomic structure are currently capable of providing the level of accuracy close to that of the most precise experiments. The multiconfiguration Hartree-Fock method is applied to calculation of the 4d--4f energy difference in Li

Methodology for Evaluating Candidate Geometric Reference Scaffolds

November 1, 2007
Author(s)
Joy P. Dunkers, Stefan D. Leigh, David Dean, M Cooke, Richard Ketcham, Marcus T. Cicerone
The motivation for the work is to rank candidate reference scaffolds by quality metrics in a systematic and quantitative manner by screening several microstructural descriptors of importance. We chose total pore volume, pore volume distribution, and pore

Rendering UML Activity Diagrams as Human-Readable Text

November 1, 2007
Author(s)
David Flater, Philippe A. Martin, Michelle L. Crane
We describe a modification of the Petri Net Linear Form notation to support the rendering of Unified Modeling Language (UML) Activity Diagrams as human-readable text. This new notation, called the Activity Diagram Linear Form, allows UML Activity Diagrams

Shear Bond Strength of Bioactive Amorphous Calcium Phosphate Composites

November 1, 2007
Author(s)
Gary E. Schumacher, Joseph M. Antonucci, Justin N. O'Donnell, Drago Skrtic
Bioactive, amorphous calcium phosphate (ACP)-filled polymeric composites in aqueous environments release significant amounts of Ca and PO4 ions leading to deposition of an apatitic mineral that is similar to that found in enamel. These materials are

Subpicotesla atomic magnetometry with a microfabricated vapour cell

November 1, 2007
Author(s)
V Shah, Svenja A. Knappe, P Schwindt, John E. Kitching
Highly sensitive magnetometers, capable of measuring magnetic fields below 1 pT, impact areas as diverse as geophysical surveying1, the detection of unexploded ordinance, space science3, nuclear magnetic resonance (NMR), and perimeter and remote monitoring
