A Hybrid CPU-GPU System for Stitching Large Scale Optical Microscopy Images

September 12, 2014
Author(s)
Timothy Blattner, Walid Keyrouz, Joe Chalfoun, Bertrand C. Stivalet, Mary C. Brady, Shujia Zhou
Researchers in various fields are using optical microscopy to acquire very large images, 10K--200K of pixels per side. Optical microscopes acquire these images as grids of overlapping partial images (thousands of pixels per side) that are then stitched

Mutual Cross Modulation of Two Laser Beams at the Individual-Photon Level

September 12, 2014
Author(s)
Michael Gullans, Kristin M. Beck, Qian Lin, M D. Lukin, Vladan Vuletic, Wenlan Chen
The realization of deterministic photon-photon interactions is a long-standing goal in optical science. Using an atomic ensemble inside a cavity, we demonstrate the mutual cross modulation of two continuous light beams at the level of individual photons

Nurturing a Disruptive Technology for Thermodynamic Metrology

September 12, 2014
Author(s)
Zeeshan Ahmed
This presenation lays out a case, based on economic and technologic considerations, that the present technologies for temperature and pressure measurement are ripe for disruption. We argue that a better use of research funds is to identify and nuture

PMML in Manufacturing Applications

September 12, 2014
Author(s)
Yung-Tsun T. Lee, Juyeon Lee
In manufacturing, an enormous amount of data, both real and simulation data, is being continuously generated. The appropriate information, if extracted from big data, could provide insights on increasing sustainability, productivity, flexibility, and

Recommended isolated-line profile for representing high-resolution spectroscopic transitions

September 11, 2014
Author(s)
Joseph T. Hodges, Jonathan Tennyson, P F. Bernath, Alain Campargue, A Csaszar, L Daumont, R R. Gamache, D Lisak, Olga Naumenko, Lawrence Rothman, Ha Tran, N Zobov, Boone Chris, L Gianfrani, Jean M. Hartmann
Recommendations of an IUPAC Task Group formed in 2011 on “Intensities and line shapes in high-resolution spectra of water isotopologues from Experiment and Theory" (Project No. 2011-022-2- 100) on line profiles of high-resolution rotational-vibrational

Degrees of Equivalence for Chemical Measurement Capabilities: Primary pH

September 10, 2014
Author(s)
David L. Duewer, Kenneth W. Pratt, Chainarong Cherdchu, Nongluck Tangpaisarnkul2 Nongluck Tangpaisarnkul2, Akiharu Hioki, Masaki Ohata, Petra Spitzer, Michal M?ri?ssy, Leo? Vysko?il
The Key Comparison (KC) studies of the Consultative Committee for Amount of Substance – Metrology in Chemistry (CCQM) help ensure the reliability of chemical and biochemical measurements relevant to international trade and environmental , health , and

Photon-number uncertainty in a superconducting transition-edge sensor beyond resolved-photon-number determination

September 10, 2014
Author(s)
Zachary H. Levine, Boris L. Glebov, Alan L. Migdall, Thomas Gerrits, Brice R. Calkins, Adriana E. Lita, Sae Woo Nam
As part of an effort to extend fundamental single-photon measurements into the macroscopic regime, we explore how best to assign photon-number uncertainties to output waveforms of a superconducting Transition Edge Sensor (TES) and how those assignments

Progress toward new Reference Correlations for the Transport Properties of Carbon Dioxide

September 10, 2014
Author(s)
Allan H. Harvey, Marcia L. Huber, Arno R. Laesecke, Chris D. Muzny, Richard A. Perkins
The thermophysical properties of carbon dioxide are essential for accurate process design and optimization. While the thermodynamic properties of CO2 are available with excellent accuracy from the reference-quality equation of state of Span and Wagner, the

Sub-wavelength interference of thermal light with photon-number resolving detection

September 10, 2014
Author(s)
Yanhua (. Zhai, Francisco E. Becerra Chavez, Jingyun Fan, Alan L. Migdall
We examine the spatial correlation of thermal-light diffracted through a double-slit using photon-number-resolved detection to directly measure high-order correlations. We observe sinusoidal modulations of the spatial coherence in the diffracted light

Fire Modeling for the Fire Research, Fire Protection, and Fire Service Communities

September 8, 2014
Author(s)
Kevin B. McGrattan, Randall J. McDermott, Glenn P. Forney, Kristopher J. Overholt, Craig G. Weinschenk, Jason E. Floyd
The Fire Dynamics Simulator (FDS) was first publicly released in 2000, and it has recently undergone its fifth major revision. Since its first release, FDS has been applied in three major areas: basic research in fire dynamics, performance-based design

Foam Composite Specifications and Qualification in Support of NIJ 0115.00

September 8, 2014
Author(s)
Aaron Forster, Emilien J. Guigues, Amanda Forster, Jeffrey M. Davis, Kirk D. Rice
A laminate foam composite is recommended in the National Institute of Justice (NIJ) 0115.00 standard as the backing material for testing stab resistant body armor. The foam specification originated from early work to match force-displacement profiles from

Robust Ferromagnetism in the Compressed Permanent Magnet Sm 2 Co 17

September 8, 2014
Author(s)
Jason R. Jeffries, L.S.I. Veiga, G. Fabbris, D. Haskel, P. Huang, Nicholas Butch, S.K. McCall, K. Holliday, Z. Jenei, Y. Xiao, P. Chow
The compound Sm 2Co 17 displays magnetic properties amenable to permanent magnet applications owing to both the 3d-electrons of Co and the 4f-electrons of Sm. The long-standing description of the magnetic interactions between the Sm and Co ions implies a

Environment-assisted quantum control of a solid state spin via 2-color coherent dark states

September 7, 2014
Author(s)
Jacob M. Taylor, Jack Hansom, Carsten Schulte, Claire Le Gall, Clemens Matthiesen, Edmund Clarke, Maxime Hugues, Mete Atature
Semiconductor quantum dots (QDs) offer an efficient and scalable interface between single spins and optical photons. However, the solid-state environment of the QD represents an inherent source of noise, generally considered detrimental to coherent control
