Scalable Entanglement of Trapped Ions

January 1, 2000
Author(s)
C Monroe, Q A. Turchette, D Kielpinski, B E. King, V Meyer, Wayne M. Itano, David J. Wineland, C J. Myatt, M A. Rowe, Christopher Langer, C A. Sackett
Entangled states are both a crucial component in quantum computers, and of great interest in their own right, highlighting the inherent nonlocality of quantum mechanics. As part of the drive toward larger entangled states for quantum computing, we have

Second Intercomparision of Radiation Temperature Scales Among Four National Metrological Laboratories Using a Transfer Standard Radiation Thermometer

January 1, 2000
Author(s)
F Sakuma, H Sakate, Graham Machin, J Fischer, Charles E. Gibson, B. Carol Johnson
Round-robin measurements with a transfer-standard radiation thermometer were organized by the National Research Laboratory of Metrology NRLM with the National Institute of Standards and Technology (NIST), National Physical Laboratory (NPL), IMGC (Institute

Seismic Rehabilitation Design of Steel Moment Connection with Welded Haunch

January 1, 2000
Author(s)
Q -. Yu, Chia-Ming Uang, John L. Gross
This paper describes a design procedure for the seismic rehabilitation of pre-Northridge steel moment connections using a welded haunch. Experimental results from cyclic testing of full-scale specimens demonstrated that welding a triangular haunch beneath

SEMPA Imaging of Domain Dynamics in Amorphous Metals

January 1, 2000
Author(s)
A Gavrin, John Unguris
We show how Scanning Electron Microscopy with Polarization Analysis (SEMPA) may be used to observe domain wall motion in amorphous ferromagnetic ribbons commonly used in transformer cores. SEMPA images were obtained from both the smooth, air side of the

Sheared Foam as a Supercooled Liquid?

January 1, 2000
Author(s)
Stephen A. Langer, A J. Liu
We conduct numerical simulations on a simple model of a two-dimensional steady-state sheared foam, and define a quantity Γ that measures pressure fluctuations in the constant-area system. This quantity reduces to the temperature in an equilibrium system

Single Fiber Composites: A New Methodology for Determining Interfacial Shear Strength

January 1, 2000
Author(s)
Gale A. Holmes, Donald L. Hunston, Walter G. McDonough, R C. Peterson
One of the critical factors controlling the long-term performance and durability of composites in structural applications is the interfacial shear strength (IFSS). The single fiber composite (SFC) test has been viewed by many as the best test for

Size Invariance of Polyelectrolyte Dendrimers

January 1, 2000
Author(s)
G Nisato, R Ivkov, Eric J. Amis
In order to quantify the swelling response of polyelectrolyte dendrimers in aqueous solutions as affected by changes in solution conditions, we have studied generation 8 poly(amido amine) (PAMAM) dendrimers in D2O using small angle neutron scattering (SANS
