  • Chruściński, Dariusz; Kossakowski, Andrzej; Pascazio, Saverio (2010-01-19)
    If the dynamics of an open quantum systems is non-Markovian, its {asymptotic} state strongly depends on the initial conditions, even if the dynamics possesses an {invariant} state. This is the very essence of memory effects. ...
  • Chruścińska, Alicja; Przegiętka, Krzysztof; Szroeder, Pawel; Oczkowski, Hubert Lucjan; Rozploch, Franciszek (Instytut Fizyki PAN, 2006)
    We found that beta-irradiated samples of crystallite graphite and multi--walled carbon nanotubes emit light during heating above room temperature. This behaviour is rather surprising for semimetals. Due to the lack of deep ...
  • Morales-Duran, Nicolas; Potasz, Paweł; MacDonald, Allan H. (American Physical Society, 2023-06-14)
    Recent experiments have established that semiconductor-based moiré materials can host incompressible states at a series of fractional moiré-miniband fillings. These states have been identified as generalized Wigner crystals ...
  • Duch, Włodzisław; Jankowski, Norbert; Maszczyk, Tomasz (Institute of Electrical and Electronics Engineers, Computational Intelligence Society, 2012-06)
    Learning methods with linear computational complexity O(nd) in number of samples and their dimension often give results that are better or at least not worse that more sophisticated and slower algorithms. This is ...
  • Chruściński, Dariusz; Kossakowski, Andrzej (2012-01-28)
    We characterize a class of Markovian dynamics using the concept of divisible dynamical map. Moreover we provide a family of criteria which can distinguish Markovian and non-Markovian dynamics. These Markovianity criteria ...
  • Balashov, Aleksandr; Bielska, Katarzyna; Li, Gang; Kyuberis, Aleksandra A.; Wójtewicz, Szymon; Domysławska, Jolanta; Ciuryło, Roman; Zobov, Nikolai F.; Lisak, Daniel; Tennyson, Jonathan (American Institute of Physics, 2023)
    Intensities of 14 lines in the sixth overtone (7–0) band of carbon monoxide (12C 16O) are measured in the visible range between 14 300 and 14 500 cm−1 using a frequency-stabilized cavity ring-down spectrometer. This is ...
  • Chruściński, Dariusz; Jurkowski, Jacek (2007-12-07)
    We analyze the new equation of motion for the damped oscillator. It differs from the standard one by a damping term which is nonlocal in time and hence it gives rise to a system with memory. Both classical and quantum ...
  • Duch, Włodzisław (Springer, 2011)
    Meta-learning methods are aimed at automatic discovery of interesting models of data. They belong to a branch of Machine Learning that tries to replace human experts involved in the Data Mining process of creating various ...

    Context. The 22.2 GHz water masers are often associated with the 6.7 GHz methanol masers but owing to the different excitation conditions they likely probe independent spatial and kinematic regions around the powering young ...
  • Szabat, Krzysztof; Pajchrowski, Tomasz; Tarczewski, Tomasz (MDPI, Basel, Switzerland, 2021-12-27)
    Modern electrical drives possess many advantages. Electrical energy, compared to other sources, is easy to transport and can be environmentally friendly (if it comes from renewable sources). Electrical drives convert ...
  • Paprocki, Marcin; Erwiński, Krystian; Grzesiak, Lech (2019)
    W artykule przedstawiono moduł komunikacyjny magistrali EtherCAT przeznaczony dla napędów elektrycznych. Omówiono standard komunikacji EtherCAT wraz z opisem działania urządzenia podrzędnego wykorzysującego profil komunikacyjny ...
  • Szymczak, Marian; Olech, Mateusz; Sarniak, Rafał; Wolak, Paweł; Bartkiewicz, Anna (Oxford University Press, 2018-02)
    We report results of 6.7 GHz methanol maser monitoring of 139 star-forming sites with theTorun 32 m radio telescope from June 2009 to February 2013. The targets were observedat least once a month, with higher ...
  • Duch, Włodzisław (Nicolaus Copernicus University Press, 2013)
    Fenomika zajmuje się szczegółowym opisem wszystkich aspektów mierzalnych cech organizmu, od fizycznych cech na poziomie genetycznym, molekularnym komórkowym, do cech opisujących zdolności poznawcze. Fenomika europsychia ...
  • Chruściński, Dariusz; Kossakowski, Andrzej (2007-10-10)
    We construct a large class of multipartite qudit states which are positive under the family of partial transpositions. The construction is based on certain direct sum decomposition of the total Hilbert space displaying ...
  • Erwiński, Krystian; Kowalski, Karol; Paprocki, Marcin (2019)
    In the article a method of predicting contour error using artificial neural network for a bi-axial positioning system is presented. The machine consists of two linear stages with permanent magnet linear motors controlled ...
  • Erwiński, Krystian; Paprocki, Marcin; Wawrzak, Andrzej; Grzesiak, Lech M. (2016-11-12)
    This article presents a method for predicting contour error using artificial neural networks. Contour error is defined as the minimum distance between actual position and reference toolpath and is commonly used to measure ...
  • Szczygielski, Krzysztof; Studziński, Michał (2024-08-28)
    In this paper, we present new families of quantum channels for which corresponding minimum output Rényi p-entropy is not additive. Our manuscript is motivated by the results of Grudka et al., J. Phys. A: Math. Theor. 43 ...
  • Rajabi, F.; Houde, M.; Bartkiewicz, Anna; Olech, Mateusz; Szymczak, Marian; Wolak, Paweł (Royal Astronomical Society, 2019-01)
    We present new evidence for superradiance (SR) in the methanol 6.7 GHz spectral line for three different star-forming regions: S255IR-NIRS3, G24.329+0.144, and Cepheus A. Our analysis shows that some of the flux–density ...
  • Perucho, Manuel; Marti, Jose-Maria; Hanasz, Michał (2005-10-14)
    The linear and non-linear stability of sheared, relativistic planar jets is studied by means of linear stability analysis and numerical hydrodynamical simulations. Our results extend the previous Kelvin-Hemlholtz stability ...
  • Chruściński, Dariusz; Kossakowski, Andrzej (2010-01-10)
    We analyze non-Markovian evolution of open quantum systems. It is shown that any dynamical map representing evolution of such a system may be described either by non-local master equation with memory kernel or equivalently ...
