the Redshift Evolution FIRST Radio Sources
font style='font-size:12px;'>
2011/1/13
We conduct a statistical analysis of the radio source population in galaxy clusters as a function of redshift by matching radio sources from the Faint Images of the Radio Sky at Twenty-Centimeters (FI...

light-absorbing aerosol arctic snow seasonal variation
font style='font-size:12px;'>
2010/11/30
Two data sets consisting of measurements of light absorbing aerosols (LAA) in arctic snow together with suites of other corresponding chemical constituents are presented; the first from Siberia, Green...
Higgs-induced spectroscopic shifts near strong gravity sources
Higgs-induced spectroscopic strong gravity sources
font style='font-size:12px;'>
2010/12/21
We explore the consequences of the mass generation due to the Higgs field in strong gravity
astrophysical environments. The vacuum expectation value of the Higgs field is predicted to depend on the c...
Spectral Index as a Function of Mass Accretion Rate in Black Hole Sources. Monte-Carlo Simulations and an Analytical Description
black hole physics accretion disks radiation mechanisms
font style='font-size:12px;'>
2010/11/16
We present herein a theoretical study of correlations between spectral indexes of X-ray emergent spectra and mass accretion rate (m˙ ) in black hole (BH) sources,which provide a definitive signature f...
Asymptotic Synchronization for Finite-State Sources
Asymptotic Synchronization Finite-State Sources
font style='font-size:12px;'>
2010/11/10
We extend a recent analysis of synchronization for exact finite-state sources to nonexact sources for which synchronization occurs only asymptotically. Although the asymptotic case requires more sophi...

2011/1/5
Short baseline oscillations of neutrinos (νe and ṽe) due to active-sterile (a-s) mixing can be observed explicitly using MeV ν beams and existing/planned ν detectors.

2010/11/10
We present results from our studies of radio emission from selectecd Ultra Luminous X-ray (ULX) sources, using archival Giant Metrewave Radio Telescope (GMRT) data and new European VLBI Network (EVN) ...
Photometric Catalogue of Quasars and Other Point Sources in the Sloan Digital Sky Survey
astronomical data bases miscellaneous – catalogues – techniques pho-tometric – methods statistical – surveys
font style='font-size:12px;'>
2010/11/12
We present a catalogue of about 8.6 million unresolved photometric detections in the Sloan Digital Sky Survey Seventh Data Release classifying them into stars, galaxies and quasars using a machine lea...
Lossy compression of discrete sources via Viterbi algorithm
Lossy compression discrete sources Viterbi algorithm
font style='font-size:12px;'>
2010/11/22
We present a new lossy compressor for discrete-valued sources. For coding a sequence $x^n$, the encoder starts by assigning a certain cost to each possible reconstruction sequence. It then finds the ...
