H Atom Attack on Propene

March 15, 2011
Author(s)
Claudette M. Rosado-Reyes, Jeffrey A. Manion, Wing Tsang
The reaction of propene(CH3CH=CH2) with hydrogen atoms has been investigated in a heated single-pulsed shock tube at temperature between 929K-1212K and pressures of 1.7bar-3.4bar. Stable products from H atom addition and H abstraction have been identified

Experimental Study of High Speed Polarization -Coding Quantum Key Distribution with Sifted -Key Rates Over Mbit/s

June 1, 2009
Author(s)
Xiao Tang, Lijun Ma, Alan Mink, Anastase Nakassis, Barry J. Hershman, Joshua C. Bienfang, David H. Su, Ronald F. Boisvert, Charles W. Clark, Carl J. Williams
We have demonstrated a polarization encoded, fiber-based quantum key distribution system operating at 850 nm in the B92 protocol. With a quantum bit transmission rate i.e. optical pulse driving frequency of 625 MHz and a mean photon number of 0.1, we

Development of backlighting sources for Compton radiography diagnostic of Inertial Confinement Fusion targets.

December 8, 2008
Author(s)
Lawrence T. Hudson, A. Tommasini, A MacPhee, D. Hey, T Ma, C. Chen, N Izimi, W Unites, A. MacKinnon, P. Hatchett, B.A. Remington, H.S. Park, P. Springer, J. Koch, O.L. Landen, John F. Seely, G Holland
We present scaled demonstrations of backlighter sources, emitting Bremsstrahlung x rays with photon energies above 75 keV, that we will use to record x-ray Compton radiographic snapshots of cold dense DT fuel in inertial confinement fusion implosions at

A Thermodynamic Study of Ketoreductase-Catalyzed Reactions, Part 5. Reduction of Substituted Ketones in n-Hexane

… reactions of 1-benzyl-3-pyrrolidinone, ethyl 2-oxo-4-phenylbutyrate, ethyl 4-chloroacetoacetate, 1-benzyl-4-piperidone, and 1-benzyl-3-piperidone were measured in … 1-benzyl-3-piperidone, 1-benzyl-3-pyrrolidinone, 1-benzyl-4-piperidone, enthalpy, equilibrium constant, ethy …

Minimal Universal Two-Qubit Controlled-NOT-Based Circuits

March 10, 2004
Author(s)
V V. Shende, I L. Markov, Stephen Bullock
… using CNOT and one-qubit gates require at least [1/4 (4n - 3n -1)] CNOT gates in the worst case. For two-qubit … circuit identities, we improve an earlier lower bound of 17 elementary gates by Bullock and Markov to 18, and their …

General Methods for Access Control Policy Verification

December 19, 2016
Author(s)
Chung Tong Hu, David R. Kuhn
Access control systems are among the most critical of computer security components. Faulty policies, misconfigurations, or flaws in software implementations can result in serious vulnerabilities. To formally and precisely capture the security properties

Towards a Domain-Specific Framework for Predictive Analytics in Manufacturing

October 3, 2014
Author(s)
David J. Lechevalier, Anantha Narayanan Narayanan, Sudarsan Rachuri
Data analytics is proving to be very useful for achieving productivity gains in manufacturing. Predictive analytics (using advanced machine learning) is particularly valuable in manufacturing, as it leads to production improvement with respect to the cost

Rotational Hysteresis of Exchange-Spring Magnets
