5 MHz Phase Detector With Low Residual Flicker

September 15, 2011
Author(s)
Corey A. Barnes, Archita Hati, Craig W. Nelson, David A. Howe
The measurement of close-to carrier phase modulation (PM) noise of state-of-the-art oscillators is always challenging. Quite often the residual noise of the phase detector used in these measurements is the source of difficulty. In particular at Fourier

Evidence for upregulated repair of oxidatively induced DNA damage in human colorectal cancer

September 15, 2011
Author(s)
M Miral Dizdar, Pawel Jaruga, Prasad T. Reddy, Guldal Kirkali, Didem Keles, Gulgun Oktay, Aras E. Canda
Molecular pathways that play a role in the development of colorectal cancer involve multiple genetic changes in cancer-related genes that may be caused by overproduction of oxygen-derived species including free radicals, which are capable of damaging DNA

Graphene: A New Horizon for Modern Technology

September 15, 2011
Author(s)
Jan Obrzut
Graphene has the potential to improve a long list of daily electronics that are the foundation of the modern computing revolution. In step with research in renewable energy, graphene can and has been used in efficient, flexible solar cells. Crossing the

High-Resolution Infrared Spectra of Spiropentane, C5H8

September 15, 2011
Author(s)
Alfons Weber, J E. Price, K A. Coulterpark, Tony Masiello, Joseph W. Nibler, A Maki, Thomas A. Blake
Infrared spectra of spiropentane (C5H8) have been recorded at a resolution (0.002 cm-1) sufficient to resolve for the first time individual rovibrational lines. This initial report presents the ground state constants for this molecule determined from the

Information System Security Best Practices for UOCAVA-Supporting Systems

September 15, 2011
Author(s)
Andrew R. Regenscheid, Geoff Beier, Santosh Chokhani, Paul Hoffman, Jim Knoke, Scott Shorter
IT systems used to support UOCAVA voting face a variety of threats. If IT systems are not selected, configured and managed using security practices commensurate with the importance of the services they provide and the sensitivity of the data they handle, a

Magnetization textures in NiPd nanostructures

September 15, 2011
Author(s)
Jean-Yves Chauleau, Benjamin James McMorran, R. Belkhou, Nicolas Bergeard, Tevfik Mente?, Miguel Angel Nino, Andrea Locatelli, John Unguris, Stanislas Rohart, Jacques Miltat, Andre Thiaville
We have observed peculiar magnetization textures in Ni80Pd20 nanostructures, by three different imaging techniques (MFM, XMCD-PEEM and SEMPA). The appearance of diamond-like domains with strong lateral charges, and of weak stripes structures brings into

Rectangular Scale-Similar Etch Pits in Monocrystalline Diamond

September 15, 2011
Author(s)
Craig D. McGray, Richard A. Allen, Marc J. Cangemi, Jon C. Geist
Etching of monocrystalline diamond in oxygen and water vapor at 1100° C through small pores in a silicon nitride film produced smooth-walled rectangular cavities. The cavities were imaged by electron microscope and measured by interferometric microscopy

Standards and Biometrics

September 15, 2011
Author(s)
Bradford J. Wing
This paper addresses the importance of standards when implementing or using biometric systems. Standards have been developed to ensure that biometric systems can effectively and accurately meet users’ needs such as protecting data integrity, privacy, and

Testing Passive UHF Tag Performance Evolution

September 15, 2011
Author(s)
Daniel G. Kuester, David R. Novotny, Jeffrey R. Guerrieri, Zoya Popovic
Trends in tag development since the introduction of the ISO 18000-6C and EPC Global standards are investigated empirically with measurements of power harvesting and backscattering performance from 20 samples of passive tags across 860-960MHz. The

Chip-scale room-temperature atomic magnetometers for biomedical measurements

September 14, 2011
Author(s)
Svenja A. Knappe, Rahul R. Mhaskar, Jan Preusser, John E. Kitching, Lutz Trahms, Tillman H. Sander
We describe a portable 4-channel array of chip-scale atomic magnetometers in a flexible flying-lead configuration. These microfabricated, uncooled sensors with volumes below 1 cm 3 demonstrate sensitivities around 100 fT/Hz 1/2 and bandwidths of several

Mathematical Modeling of Wildland-Urban Interface Fires.

September 14, 2011
Author(s)
Randall J. McDermott, Ronald Rehm
This paper presents a simple model to demonstrate the effect on grass-fire propagation of the winds induced by structural fires in a Wildland-Urban Interface (WUI) setting. The model combines an empirical formula for wind-driven grass-fire spread and a

MEASUREMENTS OF EFFECTIVE DIFFUSION COEFFICIENT OF HELIUM AND HYDROGEN THROUGH GYPSUM

September 14, 2011
