Networks of digital humanities scholars: The informational and social uses and gratifications of Twitter
Anabel Quan-Haase, Kim Martin, Lori McCay-Peet
Big data research is currently split on whether and to what extent Twitter can be characterised as an informational or social network. We contribute to this line of inquiry through…
A Fast Algorithm for Computing the p-Curvature
Alin Bostan, Xavier Caruso, Éric Schost
We design an algorithm for computing the -curvature of a differential system in positive characteristic . For a system of dimension with coefficients of degree at most $d…
Bound state properties and photodetachment of the negatively charged hydrogen ions
Alexei M. Frolov
Absorption of infrared and visible radiation from stellar emission spectra by the negatively charged hydrogen ions H is considered. The explicit formula for the photodetachme…
Gravitational Wave Background in the Quasi-Steady State Cosmology
J. V. Narlikar, S. V. Dhurandhar, R. G. Vishwakarma +2
This paper calculates the expected gravitational wave background (GWB) in the quasi-steady state cosmology (QSSC). The principal sources of gravitational waves in the QSSC are the…
Investigating the Structure of the Windy Torus in Quasars
S. C. Gallagher, J. E. Everett, M. M. Abado +1
Thermal mid-infrared emission of quasars requires an obscuring structure that can be modeled as a magneto-hydrodynamic wind in which radiation pressure on dust shapes the outflow.…
Ultraviolet/X-ray variability and the extended X-ray emission of the radio-loud broad absorption line quasar PG 1004+130
A. E. Scott, W. N. Brandt, B. P. Miller +2
We present the results of recent Chandra, XMM-Newton, and Hubble Space Telescope observations of the radio-loud (RL), broad absorption line (BAL) quasar PG 1004+130. We compare our…
