GPS Jamming and GPS Carrier-Phase Time Transfer

January 25, 2016
Author(s)
Jian Yao, Marc A. Weiss, Charles Curry, Judah Levine
This paper studies the impact of GPS jamming on GPS carrier-phase time transfer. To study this issue, at NIST, we have installed a commercial GPS jamming detector since 2014 April. During 2014 April – 2015 April, the detector detected more than 100 jamming

Lateral Tip Control Effects in CD-AFM Metrology: The Large Tip Limit

January 25, 2016
Author(s)
Ronald G. Dixson, Ndubuisi G. Orji, Ryan Goldband
Sidewall sensing in CD-AFMs usually involves continuous lateral dithering of the tip or the use of a control algorithm and fast response piezo actuator to position the tip in a manner that resembles touch-triggering of coordinate measuring machine (CMM)

Evaluation of microbial qPCR workflows using engineered Saccharomyces cerevisiae

January 24, 2016
Author(s)
Sandra M. Da Silva, Lindsay Harris, Nathanael David Olson, Steven Lund, Autumn S. Downey, Zvi Kelman, Marc L. Salit, Jayne D. Morrow
Aims: We describe the development and interlaboratory study of modified Saccharomyces cerevisiae as a candidate material to evaluate a full detection workflow including DNA extraction and quantitative polymerase chain reaction (qPCR). Methods and results

Performance Evaluation of Human Detection Systems for Robot Safety

January 22, 2016
Author(s)
William P. Shackleford, Geraldine Cheok, Tsai H. Hong, Kamel Saidi, Michael O. Shneier
Detecting and tracking people is becoming more important in robotic applications because of the increasing demand for collaborative work in which people interact closely with and in the same workspace as robots. New safety standards allow people to work

Concentric transmon qubit featuring fast tunability and an anisotropic magnetic dipole moment

January 21, 2016
Author(s)
Jochen Braumuller, Martin O. Sandberg, Michael Vissers, Andre Schneider, Steffen Schlor, Lukas Grunhaupt, Hannes Rotzinger, Michael Marthaler, Alexander Lukashenko, Amadeus Dieter, Alexey V. Ustinov, Martin Weides, David P. Pappas
We present a planar qubit design based on a superconducting circuit that we call concentric transmon. While employing a straightforward fabrication process using Al evaporation and lift-off lithography, we observe qubit lifetimes and coherence times in the

Effect of Hierarchical Cluster Formation on the Viscosity of Concentrated Monoclonal Antibody Formulations Studied by Neutron Scattering

January 21, 2016
Author(s)
P. Douglas Godfrin, Isidro E. Zarraga, Jonathan Zarzar, Lionel Porcar, Peter Falus, Norman J. Wagner, Yun Liu
Recently, reversible cluster formation has been identified as an underlying cause of anomalously large solution viscosities observed in some concentrated monoclonal antibody (mAb) formulations. As high solution viscosity prevents the use of subcutaneous

Experimental demonstration of deep frequency modulation interferometry

January 21, 2016
Author(s)
Katharina-Sofie Isleif, Oliver Gerberding, Thomas Schwarze, Moritz Mehmet, Gerhard Heinzel, Felipe Guzman
Experiments for space and ground-based gravitational wave detectors often require large dynamic range interferometric position readout of test masses with 1 pm/√Hz precision over long time scales. Heterodyne interferometer schemes that achieve such

Lightweight, flexible, high-performance carbon nanotube cables by scalable flow coating*

January 21, 2016
Author(s)
Nathan D. Orloff, Francesca Mirri, Aaron M. Forster, Rana NMN Ashkar, Robert Headrick, E. A. Bengio, Christian J. Long, April Choi, Yimin Luo, Angela R. Hight Walker, Paul Butler, Kalman D. Migler, Matteo Pasquali
Coaxial cables for data transmission are ubiquitously used in telecommunications, aerospace, automotive and robotics industries. Unfortunately, the metals used to make commercial cables are heavy and stiff. These undesirable traits are particularly
