The spectrum of Fe II

Author(s)
Gillian Nave, S Johansson
The spectrum of singly-ionized iron (Fe II) has been recorded using high-resolution Fourier transform and grating spectroscopy over the wavelength range 900 Å

An Assessment of Methods for Determining Wind Loads

Author(s)
Emil Simiu, Chris Letchford, Nicholas Isyumov, Arindam Chowdhury, DongHun Yeo
The purpose of this work is to present an assessment of methods for determining wind loads on buildings and other structures that warrant comment, correction or

Oxidatively Induced DNA Damage and Cancer

Author(s)
M Miral Dizdar
Endogenous and exogenous sources cause oxidatively induced DNA damage in living organisms by a variety of mechanisms. Resulting DNA lesions are mutagenic and

Hybrid Electro-Optically Modulated Microcombs

Author(s)
Pascal P. Del'Haye, Scott B. Papp, Scott A. Diddams
Optical frequency combs based on mode-locked lasers have proven to be invaluable tools for a wide range of applications in precision spectroscopy and metrology

Carolyn R. Steffen, Margaret C. Kline, John Butler, Robert S. McLaren, Jaynish Patel, Margaret Ewing, Douglas R. Storts, Fabrice Noel, Sophie Dognaux
The SE33 locus is one of the most polymorphic markers used in human identification. However, it also possesses multiple microvariants both within the repeat and

Loop Structure Stability of a Double-Well-Lattice BEC

Author(s)
James V. Porto, Hoi-Yin Hui, Ryan Barnett, Sankar Das Sarma
In this work, we consider excited many-body mean-field states of bosons in a double-well optical lattice by investigating stationary Bloch solutions to the non
