Spectroscopy of Close Companions to QSOs and the Ages of Interaction-Induced Starbursts [PDF]

open access: yes, 1997
We present low-resolution absorption-line spectra of three candidate close ( < 3 arcsec) companions to the low redshift QSOs 3CR 323.1, PG 1700+518, and PKS 2135-147.

Clutter Suppression Method for Off-Grid Effects Mitigation in Airborne Passive Radars with Contaminated Reference Signals

open access: yesSensors, 2021
For an airborne passive radar with contaminated reference signals, the clutter caused by multipath (MP) signals involved in the reference channel (MP clutter) corrupts the covariance estimation in space-time adaptive processing (STAP).

Fault tolerance via diversity for off-the-shelf products: A study with SQL database servers [PDF]

open access: yes, 2007
If an off-the-shelf software product exhibits poor dependability due to design faults, then software fault tolerance is often the only way available to users and system integrators to alleviate the problem.

Splanchnic vein thromboses associated with myeloproliferative neoplasms: An international, retrospective study on 518 cases

open access: yesAmerican journal of hematology/oncology, 2019
Myeloproliferative Neoplasms (MPN) course can be complicated by thrombosis involving unusual sites as the splanchnic veins (SVT). Their management is challenging, given their composite vascular risk.

Discovery of an ultramassive pulsating white dwarf [PDF]

open access: yes, 2013
We announce the discovery of the most massive pulsating hydrogen-atmosphere (DA) white dwarf (WD) ever discovered, GD 518. Model atmosphere fits to the optical spectrum of this star show it is a 12,030 +/- 210 K WD with a log(g) = 9.08 +/- 0.06, which ...

TIME SEQUENCE SPECTROSCOPY OF AW UMa. THE 518 nm Mg I TRIPLET REGION ANALYZED WITH BROADENING FUNCTIONS [PDF]

open access: yes, 2014
High-resolution spectroscopic observations of AW UMa, obtained on three consecutive nights with a median time resolution of 2.1 minutes, have been analyzed using the broadening function method in the spectral window of 22.75 nm around the 518 nm Mg i ...

Optical Lattice Induced Light Shifts in an Yb Atomic Clock [PDF]

open access: yes, 2008
We present an experimental study of the lattice induced light shifts on the 1S_0-3P_0 optical clock transition (v_clock~518 THz) in neutral ytterbium. The ``magic'' frequency, v_magic, for the 174Yb isotope was determined to be 394 799 475(35)MHz, which ...
