  • Szymczak, Marian; Wolak, Paweł; Bartkiewicz, Anna; Aramowicz, Mirosława; Durjasz, Michał (EDP Sciences, 2020)
    Context. The excited states of OH masers detected in the environment of high-mass young stellar objects (HMYSOs) are important for improving our understanding of the physical conditions of these objects and also provide ...
  • Volvach, L. N.; Volvach, A. E.; Larinov, M. G.; MacLeod, G. C.; Wolak, Paweł; Olech, Mateusz; Kramer, B.; Menten, K.; Kraus, A.; Brand, J.; Zanicelli, A.; Poppi, S.; Rigini, S. (Astronomy Letters, 2019-06-25)
    —Powerful flares in Galactic kilomasers are closely associated with regions of intense star formation. They contribute to the elucidation of physical processes occurring in these structures. We have recorded a superpowerful ...
  • Kaczmarek, S.M.; Leniec, G.; Bodziony, T.; Fuks, H.; Kowalski, Z.; Drozdowski, W.; Berkowski, M.; Głowacki, M.; Witkowski, M.E.; Makowski, M. (2019)
    Single crystals of BaWO4, BaWO4:0.5at.%Ce; BaWO4:1at.%Ce; BaWO4:0.5at.%Ce,1at.%Na; and BaWO4:1at.%Ce,2at.%Na were grown from an inductively heated iridium crucible by the Czochralski method on a Malvern MSR4 puller. They ...
  • Chruściński, Dariusz; Kossakowski, Andrzej (2010-11-02)
    We provide a simple class of 2-qudit states for which one is able to formulate necessary and sufficient conditions for separability. As a byproduct we generalize well known construction provided by Horodecki et al. for ...
  • Duch, Włodzisław; Pilichowski, Maciej (2013)
    Human-level intelligence implies creativity, not only on the grand scale, but primarily in the everyday activity, such as understanding intentions, behavior, and invention of new words. Psychological models of creativity ...
  • Duch, Włodzisław (Nicolaus Copernicus University Press, 2013)
    Phenomics is concerned with detailed description of all aspects of organisms, from their physical foundations at genetic, molecular and cellular level, to behavioural and psychological traits. Neuropsychiatric phenomics ...
  • Otmianowska-Mazur, Katarzyna; Soida, Marian; Kulesza-Żydzik, Barbara; Hanasz, Michał; Kowal, Grzegorz (2008-12-11)
    In the present paper we construct maps of polarized synchrotron radio emission of a whole galaxy, based on local models of the cosmic ray (CR) driven dynamo. We perform numerical simulations of the dynamo in local Cartesian ...
  • Strzałkowski, Karol (Elsevier, 2014)
    In this work a complete thermal characterization of Cd1-x-yZnxMgxSe mixed crystals was carried out. Bulk semiconductors under investigation were grown from the melt by a high pressure modified Bridgman method for different ...
  • Drozdowski, Winicjusz; Przegiętka, Krzysztof; Wojtowicz, Andrzej J.; Oczkowski, Hubert Lucjan (Institute of Physics, Polish Academy of Sciences, 1999)
    Thermoluminescence of CaF2:Ce, BaF2, and BaF2:Ce irradiated at room temperature is reported. X-ray induced emission spectra of the samples show that both excitonic (due to e- + VK recombination) and Ce3+ d-f luminescence ...
  • Oczkowski, Hubert Lucjan; Przegiętka, Krzysztof; Wybourne, Brian; Kachnic, Marek; Krawiec, Arkadiusz (Elsevier Science Ltd, 1996)
    The initial interest in the total inventory of the radionuclide fission products ejected from Chernobyl has been replaced with concern about the deposition and accumulation in the environment of those isotopes with longer ...
  • Przegiętka, Krzysztof; Chruścińska, Alicja; Oczkowski, Hubert Lucjan; Molewski, Paweł (Versita, 2008)
    The subject of the investigations presented here is fixing dilemmatic character (transgressive or recessive) of the Poznań phase of the Vistulian (Weichselian) Glaciation and answering the question about the possibility ...
  • Bylicka, Bogna; Chruściński, Dariusz (2011-04-10)
    We analyze a class of 2-qudit circulant states. They define generalization of well known 2-qubit X-states. We formula the necessary and sufficient criteria for vanishing quantum discord. We illustrate our analysis by an ...
  • Drążkowska, Joanna; Hanasz, Michał; Kowalik, Kacper (2010-09-03)
    We present a new particle module of the magnetohydrodynamic (MHD) Piernik code. The original multi-fluid grid code based on the Relaxing Total Variation Diminishing (RTVD) scheme has been extended by addition of dust ...
  • Kozłowska, Anna; Wyrąbkiewicz, Kamil; Boniewicz, Mirosław (2013-08-14)
    The article compares the speed of ant algorithm implemented on the processor and the graphics card in the assignment problem. It is a fundamental issue optimization-combinatorial operations research. In computer science ...
  • Duch, Włodzisław (Springer, 2011)
    Understanding brain processes behind creativity and modeling them using computational means is one of the grand challenges for systems biology. Computational creativity is a new field, inspired by cognitive psychology and ...
  • Hanasz, Michał; Lesch, Harald (2003-03-27)
    We investigate favourable circumstances for fast magnetic reconnection in astrophysical plasmas based on recent results by Rogers et al. (2001). Given that a critical magnetic field structure with antiparallel field lines ...
  • Chruściński, Dariusz; Pytel, Justyna; Sarbicki, Gniewomir (2009-07-14)
    We provide a new class of indecomposable entanglement witnesses. In 4 x 4 case it reproduces the well know Breuer-Hall witness. We prove that these new witnesses are optimal and atomic, i.e. they are able to detect the ...
  • Chruściński, Dariusz; Pytel, Justyna (2010-06-15)
    We provide a class of optimal nondecomposable entanglement witnesses for 4N x 4N composite quantum systems or, equivalently, a new construction of nondecomposable positive maps in the algebra of 4N x 4N complex matrices. ...
  • Duch, Włodzisław; Szymański, Julian (2012)
