... Acceleration of particles in the vicinity of a massive black hole We propose a two-step mechanism for charged particle acceleration in the magnetosphere of a massive black hole surrounded by an accretion disk. Particles first gain energy by stochastic process during the accretion phase. It is shown that effective proton acceleration up to energies eV is possible in the turbulent magnetized accretion disk. ...

... Configuration The dictionary accepts one obligatory parameter - RULES, which has to be set to the file describing parsing rules and output recipes. ... Each non-empty line is either a comment (when started with '#' symbol), or a conversion rule, and in the latter case has to contain whitespace-separated pattern and output recipe. Currently, pattern has to match the _integer_ (one, two or more) number of input tokens; they will be replaced with a single one. ...

... GCR and SCR are primary cosmic rays. 10-15 years after the discovery of cosmic radiation (1919) there emerged two main avenues of investigation in the physics of cosmic rays (CR): 1) nuclear - elucidation of the origin of elementary particles and nuclear interactions; and 2) astrophysical (space physics) - solution of the problem related to the origin and variations (changes in intensity) of CR. ... Besides, the CR flux in interplanetary space is, strictly speaking, not isotropic. ...
