Surface Plasmon Polariton Raman Microscopy

January 1, 2012
Author(s)
Hae-Wook Yoo, Lee J. Richter, Hee-Tae Jung, Chris A. Michaels
We report surface plasmon polariton (SPP) mediated Raman microscopy on dielectric films in contact with a Ag layer at 785 nm with spatial resolution approaching the optical diffraction limit and reasonable spectral acquisition times. The excitation and

The BIOREMA project part 3: International interlaboratory comparison for bio-ethanol test methods

January 1, 2012
Author(s)
Michele M. Schantz, Adriaan van der Veen, Hugo Ent, Annaratia Baldan, Valnei Cunha, Romeu Daroda, Manuela Ulberth-Buchgraber, Brian E. Lang, Andrea Held, Ruth Hearn, Richard Brown, Paul Brewer
The main objective of the BIOREMA (Reference Materials for Biofuel Specifications) project is the development of two test materials (one bio-ethanol material and one biodiesel material) with well-established reference values. This paper describes the

Wildland Fires within Municipal Jurisdictions

January 1, 2012
Author(s)
Douglas S. Thomas, David T. Butry
Each year, wildland fires threaten structures and occupants of the wildland-urban interface (WUI). Currently, wildfire ignition estimates largely exclude ignitions originating within municipal jurisdictions, whose jurisdiction encompasses the majority of

A Novel Method for Determining the Lower Bound of Antenna Efficiency

December 31, 2011
Author(s)
Jason B. Coder, John M. Ladbury, Mark Golkowski
Determining the absolute antenna efficiency has been a difficult task since the inception of the antenna itself. While there are methods that can measure an antenna’s efficiency, most are complicated and prone to high uncertainties. A new method is

Social and Physical Aspects of Seismic Risk

December 31, 2011
Author(s)
Carmen D. Gon?alves, Antonio Possolo
Seismic risk has social and physical aspects: although very different in nature, they are intertwined and share striking similarities. Seismic risk assessment involves models and data, and judgments of the potential impact of earthquakes, which must be

The LaTeXML Daemon: Editable Math on the Collaborative Web

December 31, 2011
Author(s)
Deyan Ginev, Heinrich Stammerjohanns, Bruce R. Miller, Michael Kohlhase
The language of the \TeX/\LaTeX} typesetting system has become all-pervasive in scientific publications and has proven its stability, convenience and expressivity in its three-decade history. With the advent of the Web 2.0 paradigm, it has also become the

Through-focus Scanning Optical Microscopy

December 31, 2011
Author(s)
Ravikiran Attota
Through-focus scanning optical microscopy (TSOM) method provides three-dimensional information (i.e. the size, shape and location) about micro- and nanometer-scale structures. TSOM, based on a conventional optical microscope, achieves this by acquiring and

2-Bromo-3,3,3-Trifluoropropene: OH Reaction Rate Constant, IR Absorption Spectrum, Ozone Depletion Potentials and Global Warming Potentials

December 30, 2011
Author(s)
Kenneth O. Patten, Victor Khamaganov, Vladimir L. Orkin, Steven L. Baughcum, Donald J. Wuebbles
The rate constant for the gas phase reaction of OH radicals with BTP (2-Bromo-3,3,3-trifluoropropene, CH2=CBrCF3) was measured using a flash photolysis resonance-fluorescence technique over the temperature range 220 K to 370 K. The Arrhenius plot was found

Contributions to anelasticity in langasite and langatate

December 30, 2011
Author(s)
Ward L. Johnson, Sudook A. Kim, Christine F. Rivenbark, Satoshi Uda
Maximization of the quality factors Q of langasite (LGS) and langatate (LGT) is necessary for optimal performance of acoustic resonators of these materials in frequency-control and high-temperature sensing applications. In this report, measurements and

Initiating Mobile Software Development - Lessons Learned From a 12-Month Project

December 30, 2011
Author(s)
Frederic J. de Vaulx, Paul Khouri Saba, Marcus W. Newrock, Bertrand C. Stivalet
As mobile devices’ capabilities keep on improving, today’s mobile software ecosystem evolves at an unprecedented speed. This evolution makes mobile software development more common and critical. Moreover, the ever-increasing number of new development

Oxidatively Induced DNA Damage and Cancer

December 30, 2011
Author(s)
M Miral Dizdar, Pawel Jaruga
Oxidatively induced DNA damage is caused by endogenous and exogenous sources in living organisms. Many resulting DNA lesions are mutagenic and lead to mutations commonly found in cancer. Repairs mechanisms exist to repair this type of DNA damage

Thermal Properties and Thermal Modeling of Ballistic Clay Box

December 30, 2011
Author(s)
Dale P. Bentz, Amanda L. Forster, Kirk D. Rice, Michael A. Riley
A critical component of hard and soft body armor testing is the utilization of a clay block behind the component being evaluated. One of the performance metrics used to evaluate products is the penetration depth into the clay of an indentation produced by

More than Moore or More Moore: a SWOT analysis

December 28, 2011
Author(s)
Herbert S. Bennett, G. D. Hutcheson
Over the last decade, the world of semiconductors has broadened its horizon from More Moore and beyond conventional scaling to More than Moore. Some first hypothesized the end of Moore’s law and the beginning of a new era. They saw it as an OR gate while

Spectroscopy of the methane N3 Band with an accurate midinfrared coherent dual-comb spectrometer

December 28, 2011
Author(s)
Esther Baumann, Fabrizio R. Giorgetta, William C. Swann, Alexander M. Zolot, Ian R. Coddington, Nathan R. Newbury
We demonstrate a high-accuracy dual-comb spectrometer centered at 3.4 υm. The amplitude and phase spectra of the P,, Q, and partial R branches of the methane Ņ3 band are measured at 25 to 100 MHz point spacing with resolution under 10 kHz and a signal-to
