Soliton dynamics of an atomic spinor condensate on a Ring Lattice

March 6, 2013
Author(s)
Indubala I. Satija, Carlos L. Pando L., Eite Tiesinga
We study the dynamics of macroscopically-coherent matter waves of an ultra-cold atomic spin-1 or spinor condensate on a ring lattice of six sites and demonstrate a novel type of spatio-temporal internal Josephson effect. Using a discrete solitary mode of

Simple Estimates of Combined StairWell / Elevator Egress in Buildings

March 5, 2013
Author(s)
Paul A. Reneke, Richard D. Peacock, Bryan L. Hoskins
This report is part of this effort to develop requirements for the use of elevators in tall building evacuations. It describes a simple tool to estimate combined stairwell / elevator egress time from buildings. It is based on methods developed in the

Two-port microwave calibration at milliKelvin temperatures

March 5, 2013
Author(s)
Leonardo M. Ranzani, Lafe F. Spietz, Zoya Popovic, Jose A. Aumentado
In this work we introduce a system for 2-port microwave calibration at millikelvin temperatures operating at the coldest stage of a dilution refrigerator by use of an adapted thru-reflect-line algorithm. We show that this can be an effective tool for

1932 A watershed year in nuclear physics

March 4, 2013
Author(s)
Joseph Reader, Charles W. Clark
1932 was the year for an amazing series of discoveries in physics. This started with the announcement of the discovery of deuterium, followed by the discoveries of the neutron and the positron, as well as artificial disintegration of nuclei by accelerators

A Hybrid CPU-GPU Approach to Fourier-Based Image Stitching of Optical Microscopy Images

March 3, 2013
Author(s)
Walid Keyrouz, Timothy J. Blattner, Bertrand C. Stivalet, Joe Chalfoun, Mary C. Brady, Shujia Zhou
We present a hybrid CPU-GPU approach for the Fourier-based stitching of optical microscopy images. This system achieves sub-minute stitching rates with large grids; it stitches a grid of 59x42 tiles in 26 seconds on a two-CPU (8 physical cores) & two-GPU

Adhesion Society Meeting Proceedings

March 3, 2013
Author(s)
Rebecca Ploeger, Aaron Forster, Donald Hunston, Etienne de la Rie, Christopher McGlinchey
Consolidating adhesives have been used throughout the centuries for the conservation of painted cultural objects- such as paintings and polychrome sculpture- and if it were not for these adhesives, many objects may not have survived to the present day

Critical thermal-conductivity enhancement in molecular fluids

March 2, 2013
Author(s)
Richard A. Perkins, Jan V. Sengers, Ilmutdin M. Abdulagatov, Marcia L. Huber
The available information for the thermal-conductivity enhancement is reviewed. We show that it can be represented by a simplified solution of the mode-coupling theory of critical dynamics with two critical amplitudes and one cutoff wave number as fluid

Characterization of the NIST Shellfish Standard Reference Material 4358

March 1, 2013
Author(s)
Svetlana Nour, Kenneth G. Inn, James J. Filliben, Hank dan der Gaast, Lee Chung Men, M.D. Calmet, P Povinec, Y Takata, M. Wisdom, K. Nakamura, Pia Vesterbacka, Ching-Chung Huang, S M. Vakulovsky
A new Shellfish Standard Reference Material (SRM 4358) was developed at the National Institute of Standards and Technology (NIST) via an international intercomparison project that involved 12 laboratories-participants from 9 countries (Table 1). This
