Growth of Planar Arrays of One-dimensional p-n Heterojunctions

September 15, 2010
Author(s)
Babak Nikoobakht, Andrew A. Herzing
We report a general method for /in-situ/ formation and hierarchical assembly of nanowire-based semiconductor heterojunctions that are electrically addressable. Heterojunctions are formed by lateral epitaxial growth of nanowires/nanowalls on a semiconductor

Measurement Uncertainties in Speaker Recognition Evaluation

September 15, 2010
Author(s)
Jin Chu Wu, Alvin F. Martin, Craig S. Greenberg, Raghu N. Kacker
The speaker recognition evaluation is an ongoing series of evaluations conducted by NIST. A detection cost function is computed over the sequence of trials provided and used for all speaker detection tests while measuring speaker detection performance. The

Modelling Type Ia Supernova Light Curves

September 15, 2010
Author(s)
Bert W. Rust, Dianne M. O'Leary, Katharine M. Mullen
Type Ia supernova light curves are characterized by a rapid rise from zero luminosity to a peak value, followed by a slower quasi-exponential decline. The rise and peak last for a few days, while the decline persists for many months. It is widely believed

Simulation Model for the IEEE 802.15.3/3b WPAN Standard

September 15, 2010
Author(s)
Kamran Sayrafian
The1IEEE 802.15.3 is an emerging technology for high data rate wireless multimedia applications in Wireless Personal Area Networks (WPAN). In this paper, a discrete event simulation model has been implemented using OPNET2 Modeler to simulate the essential

Statistical Modeling Cement Heat of Hydration

September 15, 2010
Author(s)
Paul E. Stutzman
The heat of hydration of hydraulic cements results from the complex sets of phase dissolution and precipitation activity accompanying the addition of water to a cement. Heat of hydration is currently measured in one of two ways: 1) through an acid

Unique para-effect in electron ionization mass spectra of bis(perfluoroacyl) derivatives of bifunctional aminobenzenes

September 15, 2010
Author(s)
Kirill V. Tretyakov, Nino G. Todua, Roman S. Borisov, Vladimir G. Zaikin, Stephen Stein, Anzor I. Mikaia
A new kind of "para-effect" under EI conditions has been discovered for a series of bis(perfluoroacyl) derivatives of o-, m- and p- phenylendiamines, hydroxybenzeneamines and mercaptobenzeneamines of a common structure RCOX C 6H 4 NHCOR (X = NH, S, O; R =

Measurement crosstalk between two phase qubits coupled by a coplanar waveguide

September 14, 2010
Author(s)
Fabio Altomare, Katarina Cicak, Mika A. Sillanpaa, Michael S. Allman, Dale Li, Adam J. Sirois, Joshua Strong, Jae Park, Jed D. Whittaker, Raymond W. Simmonds
We investigate measurement crosstalk in a system with two flux-biased phase qubits coupled by a resonant coplanar waveguide cavity. After qubit measurement, the superconducting phase undergoes damped oscillations in a deep anharmonic potential producing a

The Thermodynamic Properties of Propane: From p-r-T to the Equation of State

September 14, 2010
Author(s)
Mark O. McLinden, Eric W. Lemmon
The p-ρ-T behavior of high-purity (99.999%) propane was measured from 265 K to 500 K with pressures to 36 Mpa using a two-sinker densimeter. The measurements extend from low-density vapor to compressed liquid states, and the near-critical region was
