Spreading alerts quietly and the subgroup escape problem

October 1, 2015
Author(s)
J. Aspnes, Z. Diamadi, A. Yampolskiy, K. Gjosteen, Rene Peralta
We introduce a new cryptographic primitive called a blind coupon mechanism (BCM). In effect, a BCM is an authenticated bit commitment scheme, which is AND-homomorphic. We show that a BCM has natural and important applications. In particular, we use it to

Timekeeping in the Americas

October 1, 2015
Author(s)
Michael A. Lombardi, Jose M. Lopez
Time and its measurement belong to the most fundamental core of physics, and many scientific and technological advances are directly or indirectly related to time measurements. Timekeeping is essential to everyday life, and thus is the most measured

Greenhouse Gas Emissions and Dispersion 3. Reducing Uncertainty in Estimating Source Strength and Location through Plume Inversion Models

September 30, 2015
Author(s)
Kuldeep R. Prasad, Adam L. Pintar, Heming Hu, Israel Lopez Coto, Dennis T. Ngo, James R. Whetstone
Recent development of accurate instruments for measuring greenhouse gas concentrations and the ability to mount them in ground based vehicles has provided an opportunity to make temporally and spatially resolved measurements in the vicinity of suspected

On the Behavior of PRES Using Incomplete Judgment Sets

September 30, 2015
Author(s)
Ellen M. Voorhees
PRES, the Patent Retrieval Evaluation Score, is a family of retrieval system evaluation measures that combines recall and user effort to better reflect the quality of a retrieval run with respect to recall-oriented search tasks. Previous analysis of the

Standardizing 25-Hydroxyvitamin D values from the Canadian Health Measures Survey

Kurtis Sarafin, Ramon Durazo-Arvizu, Lu Tian, Karen W. Phinney, Susan Tai, Johanna Camara, Hubert W. Vesper, Joyce M. Merkel, Evan Green, Christopher T. Sempos, Stephen P. Brooks
Background: The Canadian Health Measures survey (CHMS) is an ongoing cross sectional national survey that includes a measure of 25-hydroxyvitamin D (25(OH)D) by Diasorin LIAISON immunoassay. The survey repeats approximately every two years with a new

Thermodynamic Properties of 1,1,1,2,2,4,5,5,5-nonafluoro-4-(trifluoromethyl)-3-pentanone: Vapor Pressure, (p, ?, T) Behavior, and Speed of Sound Measurements, and Equation of State

Mark O. McLinden, Richard A. Perkins, Eric W. Lemmon, Tara J. Fortin
We report comprehensive thermodynamic property measurements of 1,1,1,2,2,4,5,5,5-nonafluoro-4-(trifluoromethyl)-3-pentanone. The p–ρ–T behavior was measured from T = (225 to 470) K with pressures up to 36 MPa using a two-sinker densimeter. These

240 Hz linewidth Brillouin laser from a microrod whispering gallery mode resonator

September 29, 2015
Author(s)
William Loh, Aurelien C. Coillet, Frederick N. Baynes, Scott B. Papp, Scott A. Diddams, Joe Becker
We demonstrate an ultra-low noise laser that oscillates based on the stimulated Brillouin scattering nonlinearity in an optical microresonator. Our Brillouin laser employs a microrod resonator whose larger mode volume compared to conventional resonators

Impact of Electricity Tariff Parameters on Net Zero Home Cost of Energy

September 29, 2015
Author(s)
Andrew P. Kuo, David Holmberg, Steven T. Bushby
Time-varying electricity rates impact the costs of operation and the value of renewable generation and storage resources. This study investigates the economic impact of electricity tariff parameters on the value of solar photovoltaic (PV) systems in the
