Athermal avalanche in bilayer superconducting nanowire single-photon detectors

March 28, 2016
Author(s)
Varun B. Verma, Martin J. Stevens, Richard P. Mirin, Sae Woo Nam
We demonstrate that two superconducting nanowires separated by a thin insulating barrier can undergo a thermal avalanche process. In this process, Joule heating caused by a photodetection event in one nanowire and the associated production of athermal

Design and synthesis of a minimal bacterial genome

March 25, 2016
Author(s)
Elizabeth A. Strychalski, Clyde A. Hutchinson III, Ray-Yuan Chuang, Vladimir Noskov, Nacyra Assad-Garcia, Tom J. Deerinck, Mark H. Ellisman, John Gill, Krishna Kannan, Bogumil J. Karas, Li Ma, James F. Pelletier, Zhi-Qing Qi, Alexander Richter, Lijie Sun, Yo Suzuki, Billyana Tsvetanova, Kim S. Wise, Hamilton O. Smith, John I. Glass, Chuck Merryman, Daniel G. Gibson, J. C. Venter
We used whole-genome design and complete chemical synthesis to minimize the 1079–kilobase pair synthetic genome of Mycoplasma mycoides JCVI-syn1.0. An initial design, based on collective knowledge of molecular biology combined with limited transposon

EUV-induced oxidation of carbon on TiO2

March 25, 2016
Author(s)
Nadir S. Faradzhev, Shannon B. Hill
Previously we reported on the etch rates of C on TiO2 by oxidizers including NO, O3 and H2O2 when irradiated by extreme ultraviolet (EUV) radiation at 13.5 nm [Faradzhev et al., J.Phys. Chem. C, 117 (2013) 23072-23081]. We demonstrated that the intensity

Laser Trackers for Large Scale Dimensional Metrology: A Review

March 25, 2016
Author(s)
Balasubramanian Muralikrishnan, Steven D. Phillips, Daniel S. Sawyer
Thirty years since their invention, laser trackers are now recognized as the measurement tool of choice in the manufacture and assembly of large components. While their general design, i.e., a ranging unit on a two-axis gimbal, has not changed

Multispectrum analysis of the Oxygen A-band

March 25, 2016
Author(s)
Joseph T. Hodges, Brian J. Drouin, D C. Benner, L.R. Brown, Matthew J. Cich, Timothy Crawford, Malathy Devi, Alexandre Guillaume, Eli Mlawer, D J. Robichaud, Oyafuso Fabiano, Keeyon Sung, Wishnow Edward, Shanshan Yu
Retrievals of atmospheric composition from near-infrared measurements require measurements of airmass to better than the desired precision of the composition. The oxygen bands are obvious choices to quantify airmass since the mixing ratio of oxygen is

Reproducibility in density functional theory calculations of solids

March 25, 2016
Author(s)
Francesca Tavazza, Kurt Lejaeghere, Stefaan Cottenier, Gustav Bihlmayer
Density functional theory (DFT) is now routinely used for simulating material properties. Many software packages are available, which makes it challenging to know which are the best to use for a specific calculation. Lejaeghere et al. compared the
