    • Quantum gravity stability of isotropy in homogeneous cosmology 

      Broda, Bogusław (North-Holland, 2011)
      It has been shown that anisotropy of homogeneous spacetime described by the general Kasner metric can be damped by quantum fluctuations coming from perturbative quantum gravity in one-loop approximation. Also, a formal ...

    • Scaling violation and the inelasticity of very high energy proton–proton interactions 

      Wibig, Tadeusz ORCID (North-Holland, 2011)
      The pseudorapidity measurements at LHC, although in the central region only, allows us to perform preliminary tests of the multiparticle production extrapolation formula inspired by the analysis of recent cosmic ray data. ...

    • Search for patterns by combining cosmic-ray energy and arrival directions at the Pierre Auger Observatory 

      Aab, A.; Abreu, P.; Aglietta, M.; Giller, Maria; Śmiałkowski, Andrzej; Szadkowski, Zbigniew ORCID; Winchen, T. (Springer Berlin Heidelberg, 2014)
      Energy-dependent patterns in the arrival directions of cosmic rays are searched for using data of the Pierre Auger Observatory. We investigate local regions around the highest-energy cosmic rays with E≥6×10^19 eV by ...

    • Semientwining Structures and Their Applications 

      Nichita, Florin F.; Parashar, Deepak; Zielinski, Bartosz (Hindawi Publishing Corporation, 2012-10-31)
      Semientwining structures are proposed as concepts simpler than entwining structures, yet they are shown to have interesting applications in constructing intertwining operators and braided algebras, lifting functors, ...

    • Surface-Bound and Volatile Mo Oxides Produced During Oxidation of Single MoS2 Crystals in Air and High Relative Humidity 

      Dabrowski, Pawel; Rogala, Maciej; Szoszkiewicz, Robert (MDPI, 2020)
      We report on the MoO3 oxides and their derivatives on microscopic 2H MoS2 flakes oxidized in air and high relative humidity at a moderate temperature range below 410 °C. We combine XPS and AFM measurements such as topography, ...

    • The Carbon Footprint Methodology in CFOOD Project 

      Stawska, Zofia ORCID; Zieliński, Bartosz; Milczarski, Piotr; Hłobaż, Artur; Maślanka, Paweł; Kosiński, Piotr (Polish Academy of Sciences Committee of Electronics and Telecommunications, 2020)
      In the paper, the research on the process of optimizing the carbon footprint to obtain the low-carbon products is presented. The optimization process and limits were analyzed based on the CFOOD project co-financed by ...

    • The covariance of chiral fermions theory 

      Gonera, Cezary ORCID; Maślanka, Paweł; Andrzejewski, Krzysztof; Gonera, Joanna ORCID; Kosinski, Piotr ORCID; Brihaye, Yves (Springer Nature, 2019)
      The quasiclassical theory of massless chiral fermions is considered. The effective action is derived using time-dependent variational principle which provides a clear interpretation of relevant canonical variables. As a ...

    • The X/gamma-ray correlation in NGC 4945 and the nature of its gamma-ray source 

      Wojaczyński, Rafał; Niedźwiecki, Andrzej (IOP Publishing for the American Astronomical Society, 2017)
      We report hints for the correlation between the X-ray and gamma-ray emission in the nearby galaxy NGC 4945, which harbors both an active galactic nucleus and a nuclear starburst region. We have divided the Fermi/LAT ...

    • Thermal induced structural and magnetic transformations in Fe_{73.5−x}Ce_{x=0,3,5,7}Si_{13.5}B_9Nb_3Cu_1 amorphous alloy 

      Antoszewska, Małgorzata; Wasiak, Michał ORCID; Gwizdałła, Tomasz ORCID; Sovak, Pavol; Moneta, Marek (Springer Netherlands, 2013)
      Structural and magnetic properties of amorphous and partly crystallized Fe_{73.5−x}Ce_{x=0,3,5,7}Si_{13.5}B_9Nb_3Cu_1 alloys, were analysed in the temperature ranging from RT to 800 °C with scanning calorimetry and ...

    • Ultrahigh Energy Neutrinos at the Pierre Auger Observatory 

      Abreu, P.; Ahlers, M.; Aglietta, M.; Ahn, E. J.; Albuquerque, I. F.

      The observation of ultrahigh energy neutrinos (UHE𝜈�s) has become a priority in experimental astroparticle physics. UHE𝜈�s can be detected with a variety of techniques. In particular, neutrinos can interact in the ...

    • Weak n-Ary Relational Products in Allegories 

      Zielinski, Bartosz; Maślanka, Paweł (MDPI AG, 2014)
      Allegories are enriched categories generalizing a category of sets and binary relations. Accordingly, relational products in an allegory can be viewed as a generalization of Cartesian products. There are several definitions ...
