... Stotskii A. A. Path length fluctuations through the Earth troposphere: turbulent model and data of observations. The spatial and temporal structure functions of path length the Earth troposphere for the whole space and time ranges constructed on the base of turbulence theory are considered. These structure functions include three domains: a power law of 5/3 (three-dimensional turbulence), a power law of 2/3 (two-dimensional turbulence) and saturation. ...

... The radio to X-ray continuum shape of quasars (gif), (Elvis et al., ... Plotted in log nufnu vs log nu (nu=frequency) space. ... Radio-loud, Radio-quiet: quasars that look virtually identical at all other wavelengths can differ by a 1000 in their radio emission. Radio-loud quasars have a powerful jet moving at relativistic speeds (i.e. close to the speed of light) made up of energetic particles, themselves moving near the speed of light in a magnetic field. ...

... On the modeling of the late optical afterglows from cosmological gamma-ray-bursts . Interaction of cosmological gamma-ray burst radiation with the dense interstellar medium of host galaxy is researched. Gas dynamical motion of interstellar medium driven by gamma-ray burst is investigated in 2D approximation for different initial density distributions of host galaxy matter and different total energy of gamma-ray burst. ...

We describe a simple method to annotate shell scripts and have a preprocessor extract a set of variables, present them to the user in a GUI (using Tcl/Tk) with context sensitive help, and run the script. ... When individual applications are (tightly) integrated into the scripting language, this offers very powerful scripts, fully graphical user interfaces and a result sometimes indistinguishable from applications. ... Here is an example header from a C-shell script with which Figure 1 was made. ...
