On The Magnitude of Random Telegraph Noise in Ultra-Scaled MOSFETs

May 2, 2011
Author(s)
Kin P. Cheung, Jason P. Campbell
Random telegraph noise (RTN) has been shown to be a more severe scaling issue than the Random Dopant Effect (RDE). However this observation relies heavily on studies which focus only on threshold voltage (VTH) fluctuations. VTH measurements make separation

Relationship between Persistent Organic Pollutants (POPs) and Ranging Patterns in Common Bottlenose Dolphins (Tursiops truncatus) from Coastal Georgia, USA

May 2, 2011
Author(s)
John Kucklick, Brian C. Balmer, Lori Schwacke, Randall Wells, Clay George, Jennifer Hoguet, Suzanne Lane, Anthony Martinez, William McLellan, Patricia Rosel, T K. Rowles, Kate Sparks, Todd Speakman, Eric Zolman, D A. Pabst
Bottlenose dolphins (Tursiops truncatus) are apex predators and common in coastal southeastern U.S. waters; as such they are indicators of persistent organic pollutants (POPs) in coastal ecosystems. The concentrations of POPs and patterns of specific

SUSTAINABLE MANUFACTURING INDICATOR REPOSITORY

May 2, 2011
Author(s)
Shaw C. Feng, Prabir Sarkar, Che B. Joung, John Carrell
Sustainable manufacturing promotes manufacturing processes that minimize environmental and social impacts while maintaining economic benefits. To achieve this, manufacturers seek metrics and measurement methods to enable them to track the progress and

Characterization of high-purity, pulsed squeezed light at telecom wavelengths from pp-KTP for quantum information applications

May 1, 2011
Author(s)
Thomas Gerrits, Burm Baek, Martin J. Stevens, Brice R. Calkins, Adriana E. Lita, Scott C. Glancy, Emanuel H. Knill, Sae Woo Nam, Richard P. Mirin, Robert Hadfield, Ryan Bennink, Warren Grice, Sander N. Dorenbos, Tony Zijlstra, Teun Klapwijk, Val Zwiller
We characterize a pp-KTP crystal designed to produce pure single mode squeezed vacuum at 1570 nm. Measurements show Hong-Ou-Mandel interference with 97% visibility and a circular joint spectral distribution with a Schmidt number of 1.08.

Characterization of the First Order Nonlinear Stiffened Elasticity of the Piezoelectric Layer in Bulk Acoustic Wave Resonators

May 1, 2011
Author(s)
Juan C. Collado Gomez, Eduard Rocas, Jordi Mateu, Nathan D. Orloff, James C. Booth, Alberto Padillo, Juan Callaghan
This work proposes a procedure to characterize the intrinsic nonlinearities of bulk acoustic wave resonators by performing one port measurements of the second harmonic and second order intermodulation spurious signals. Closed-form expressions have been

DEoptim: An R Package for Global Optimization by Differential Evolution

May 1, 2011
Author(s)
Katharine M. Mullen, David Ardia , David L. Gil, Donald A. Windover, James P. Cline
This article describes the R package DEoptim which implements the differential evolution algorithm for the global optimization of a real-valued function of a real-valued parameter vector. The implementation of differential evolution in DEoptim interfaces

Dual comb spectroscopy from 1.25 to 1.7 ym

May 1, 2011
Author(s)
Alexander M. Zolot, Ian R. Coddington, Fabrizio R. Giorgetta, Esther Baumann, William C. Swann, Nathan R. Newbury
A coherent dual comb spectrometer spanning much of the near infrared was constructed from broadened erbium fiber lasers. Gas phase water, methane and acetylene spectra were measured and characterized toward establishing new frequency standards.

Dual-comb based measurement of frequency agile lasers.

May 1, 2011
Author(s)
Ian R. Coddington, Fabrizio R. Giorgetta, Esther Baumann, William C. Swann, Nathan R. Newbury
Properly stabilized, frequency combs form high accuracy references across much of the optical spectrum. Here we employ dual frequency combs to harness this accuracy for fast and high resolution measurements of swept CW sources.
