Archaeal DNA replication

Author(s)
Zvi Kelman, Lori M. Kelman
DNA replication is an essential process for all life forms. While the process is fundamentally conserved in the three domains of life, bioinformatics

Fast Neutron Detection with a Segmented Spectrometer

Author(s)
Jeffrey S. Nico, T J. Langford, Christopher D. Bass, H Breuer, Craig Heimbach, D. K. Erwin
A fast neutron spectrometer consisting of segmented plastic scintillator and He-3 proportional counters was constructed for the measurement of neutrons in the

Frequency Comb Generation in Superconducting Resonators

Author(s)
Robert P. Erickson, Michael Vissers, Martin O. Sandberg, Steven R. Jefferts, David P. Pappas
We have generated frequency combs spanning 0.5 to 20 GHz in superconducting λ=2 resonators at T ¼ 3 K. Thin films of niobium-titanium nitride enabled this

Frequency-Comb-Based Remote Sensing of Greenhouse Gases over Kilometer Air Paths

Author(s)
Greg B. Rieker, Fabrizio R. Giorgetta, William C. Swann, Jonathan Kofler, Alexander M. Zolot, Laura C. Sinclair, Esther Baumann, Christopher L. Cromer, G. Petron, Colm Sweeney, P P. Tans, Ian R. Coddington, Nathan R. Newbury
We demonstrate frequency comb tooth-by-tooth measurements of atmospheric gas absorption across a 2-km, turbulent, open-air path through coherent dual-comb

Carbon Monoxide Exposure from Portable Generators

Author(s)
Steven J. Emmerich, Andrew K. Persily, Liangzhu Wang
Serious concerns exist about the hazard of acute residential carbon monoxide (CO) exposures from portable gasoline-powered generators, which can result in death

Nanoscale Structural Heterogeneity in Ni-rich Half-Heusler TiNiSn

Author(s)
Jason E. Douglas, Philip A. Chater, Craig Brown, Tresa M. Pollock, Ram Seshadri
The structural implications of excess Ni in the TiNiSn half-Heusler compound are examined through a combination of synchrotron x-ray and neutron scattering

Nanoparticle size determination using optical microscopes

Author(s)
Ravikiran Attota, Richard J. Kasica, Premsagar P. Kavuri, Hyeong G. Kang, Lei Chen
We present a simple method for size determination of nanoparticles using conventional optical microscopes. The method, called through-focus scanning optical
