Structure, spectra and variability of some GPS radio sources [PDF]

Astron. Nachr. / AN 330, No. 2/3, 145 - 148 (2009), 2010
We report the results of multifrequency-VLBI observations of GHz-Peaked-Spectrum (GPS) radio sources. The VLBI structure and component spectra of some GPS sources are presented. Our VLBI results show that about 80% of the GPS galaxies exhibit a compact double or CSO-like structure, while the GPS quasars tend to show a core-jet. The component spectra of

A Giant Sample of Giant Pulses from the Crab Pulsar [PDF]

The Astrophysical Journal, 760:64 (13pp), 2012, 2012
We observed the Crab pulsar with the 43-m telescope in Green Bank, WV over a timespan of 15 months. In total we obtained 100 hours of data at 1.2 GHz and seven hours at 330 MHz, resulting in a sample of about 95000 giant pulses (GPs). This is the largest sample, to date, of GPs from the Crab pulsar taken with the same telescope and backend and analyzed

Quantification of the variation in percentage identity for protein sequence alignments [PDF]

BMC Bioinformatics, 2006
Background Percentage Identity (PID) is frequently quoted in discussion of sequence alignments since it appears simple and easy to understand. However, although there are several different ways to calculate percentage identity and each may yield a ...

Quasi-simultaneous multi-frequency observations of inverted-spectrum GPS candidate sources [PDF]

, 2008
Gigahertz-Peaked Spectrum (GPS) sources are probably the precursors of local radio galaxies.Existing GPS source samples are small (<200). It is necessary to extend the availabe sample of the Gigahertz-Peaked Spectrum (GPS) and High Frequency Peaker (HFP) sources in order to study their nature with greater details and higher statistical significance.

GP or No GP, Is That the Question? [PDF]

Circulation: Arrhythmia and Electrophysiology, 2013
It has long been recognized, on the basis of numerous experimental and clinical studies, that the autonomic nervous system has a significant role in the pathogenesis of atrial fibrillation (AF). More recent studies have focused on the ganglionated plexi (GP), which are part of an interconnected structural and functional atrial neural network ...

Precise Orbit Determination of GPS-36 Satellite Using Satellite Laser Ranging [PDF]

Journal of Astronomy and Space Sciences, 2002
Satellite laser ranging is a technique for precisely measuring the range between a laser station and a satellite that is equipped with retro-reflectors. SLR technique was first used for Beacon-B satellite in 1964 with the ranging accuracy of meter level.
