    • ULTRAHIGH ENERGY COSMIC RAYS: REVIEW OF THE CURRENT SITUATION 

      Autor: Stanev, Todor
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
      We describe the current situation of the data on the highest energy particles in the Universe – the ultrahigh energy cosmic rays. The new results in the field come from the Telescope Array experiment in Utah, U.S.A. For ...

    • Velikhov Electrothermal Instability Cancellation by a Modification of Electrical Conductivity Value in a Streamer by Magnetic Confinement 

      Autor: Petit , Jean P.; Dore , Jean C.
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
      We present a method, confirmed experimentally, allowing the cancellation of Velikhov instability by operating a local magnetic field reduction along a lane, which enhances local electric conductivity and electron-gas ...

    • Weakly Ordered A-Commutative Partial Groups of Linear Operators Densely Defined on Hilbert Space 

      Autor: Janda , Jirí
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
      The notion of a generalized effect algebra is presented as a generalization of effect algebra for an algebraic description of the structure of the set of all positive linear operators densely defined on a Hilbert space ...

    • WHAT IS NEW IN ASTROPARTICLE PHYSICS 

      Autor: Giovannelli, Franco
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
      In this brief review paper I will point to the most important steps that have been made in recent decades toward a better understanding of the physics governing our Universe. Because of the limited length of this paper, I ...

    • X-ray Spectroscopic Characterization of Shock-Ignition-Relevant plasmas 

      Autor: Šmíd , Michal; Antonelli , Luca; Renner , Oldoich
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
      Experiments with multilayer plastic/Cu targets performed at a PALS laser system aimed at the study of matter at conditions relevant to a shock ignition ICF scheme, and, in particular, at the investigation of hot electrons ...

    • XMM-NEWTON SCIENTIFIC HIGHLIGHTS: X-RAY SPECTROSCOPIC POPULATION STUDIES OF AGN 

      Autor: Guainazzi, Matteo
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
      In this paper I review the contribution that the XMM-Newton ESA X-ray mission has given to our understanding of Active Galactic Nuclei, together with other operational, and complementary, X-ray facilities. I will focus on ...
