3. Keywords_279
About Zones of Resonant Returns of Asteroid Apophis . ... Asteroid Apophis is one of extremely dangerous NEOs. ... Using analytical and numerical tools, we investigate the loss of precision after the Earth approach in 2029 and the possible approach in 2036. ... Possible trajectories of collisions with the Earth have been found analytically and numerically in this chaotic region. To construct these trajectories we used quasi-random intermediate motions, made up from resonant collision orbits. ...

4. http://star.arm.ac.uk/~ambn/abstract173.html
In this new series we present observations and modelling of spectral lines formed in main sequence star chromospheres (from G0 to M8). in this paper, we discuss the Hydrogen line formations in very active dMe stellar chromospheres. ... Our final model atmosphere is described in the next paper in this series. ... We found that observations are best reproduced by a chromospheric structure including a constant temperature gradient (in a log(M) scale) in the chromosphere and transition region. ...

12. Polarization/Stokes Handling (stokes and select)
... The visibility datasets possibly contain correlations for different polarizations and Stokes parameters. There are two basic ways that polarization characteristics can be measured: firstly, two orthogonal feeds can be present on the antennas, and the four different polarization correlations from a baseline can be taken and recorded. ... There are two ways the user can determine which polarizations he or she wants to process, either with the select parameter, or with the stokes parameter. ...

15. IUM10 conference: A.Braverman
... Recently V.Drinfeld proved that the scheme of maps from a formal disc to a (possibly singular) algebraic variety for which the image of the generic point of the disc is non-singular has essentially finite dimensional singularities (we shall explain Drinfeld's result in detail). We shall present a conjecture about a possible application of the above result to the study of automorphic L-functions and discuss some specific examples. ...
