(2014-05-26)(LuxY1-x)3Al5O12:Pr (x = 0.25, 0.50, 0.75) crystals have been grown by the Czochralski method and their scintillation properties have been examined. Compared to the well-respected LuAG:Pr scintillator, which has so extensively ...

(2011-01-12)Radio observations show that magnetic fields are present in dwarf irregular galaxies (dIrr) and its strength is comparable to that found in spiral galaxies. Slow rotation, weak shear and shallow gravitational potential are ...
-
(Monthly Notices of the Royal Astronomical Society, 2019-04-01)Discovery of periodic maser emission was an unexpected result from monitoring observations of methanol transitions in high-mass young stellar objects. We report on the detection of five new periodic sources from a monitoring ...
-
(2023-11-08)We developed a method of aligning silver nanowires in a microchannel and fixing them to glass substrates via appropriate functionalization. The attachment of nanowires to the substrate is robust with no variation of their ...
-
(2004-02-27)We present the first numerical model of the magnetohydrodynamical cosmic-ray (CR) driven dynamo of the type proposed by Parker (1992). The driving force of the amplification process comes from CRs injected into the galactic ...
-
(Elsevier B.V., 2013)The aim of this work was to study the effect of the quality of optical bleaching on the results of OSL (Optically Stimulated Luminescence) dating method. The large aliquots of coarse quartz grains extracted from fluvial ...
-
(Springer, 2012)An approach to the word sense disambiguation (WSD) relaying on the WordNet synsets is proposed. The method uses semantically tagged glosses to perform a process similar to the spreading activation in semantic network, creating ...
-
(2013-03-20)In computerized numerical control (CNC) systems, the communication bus between the controller and axis servo drives must offer high bandwidth, noise immunity, and time determinism. More and more CNC systems use real-time ...

(Wydawnictwo Uniwersytetu Warszawskiego, 2010)Architektury kognitywne (AK) są próbą stworzenia modeli komputerowych integrujących wiedzę o działaniu umysłu. Ich zadaniem jest implementacja konkretnych schematów działania funkcji poznawczych umożliwiająca testowanie ...
-
(sciendo, 2021-11-10)This paper focuses on designing a gain-scheduled (G-S) state feedback controller (SFC) for synchronous reluctance motor (SynRM) speed control with non-linear inductance characteristics. The augmented model of the drive ...
-
(2014-02-19)Analysis of dynamics of biologically motivated neural networks allows for studying non-linear processes responsible for cognitive functions and thus provides adequate language to understand complex mental processes, including ...
-
(2014-02-19)The autor tries to answer the questions: How can we understand neurodegenerative disease, such as autism, ADHD or epilepsy? Who is in the best position to do it? Observations: what do we know? Theories: do we understand ...

(Wydawnictwo Naukowe UMK, 2013)Dynamiczny rozwój Internetu sprawił, iż na przestrzeni ostatnich lat usługi sieciowe stały się nieodzowną częścią naszego życia. Coraz częściej spotykamy się z sytuacjami, w których wiele spraw znacznie łatwiej i szybciej ...
-
(2010)We analyze special class of bipartite states - so called Bell diagonal states. In particular we provide new examples of bound entangled Bell diagonal states and construct the class of entanglement witnesses diagonal in the ...
-
(2010-04-08)We analyze a class of dynamics of open quantum systems which is governed by the dynamical map mutually commuting at different times. Such evolution may be effectively described via spectral analysis of the corresponding ...
-
(2012-11-05)Exposed positive maps in matrix algebras define a dense subset of extremal maps. We provide a class of indecomposable positive maps in the algebra of 2n x 2n complex matrices with n>1. It is shown that these maps are exposed ...
-
(2007-11-28)We construct a new class of positive indecomposable maps in the algebra of `d x d' complex matrices. These maps are characterized by the `weakest' positivity property and for this reason they are called atomic. This class ...
-
(IOP Science, 2017-02)Interior of Czochralski-grown (Lu,Y)AG:Pr crystals has been examined by means of several techniques, such as X-Ray Photoelectron Spectroscopy, X-Ray Diffraction, Time-of-Flight Secondary Ion Mass Spectrometry, and magnetic ...
-
(2011-01-30)We provide a multi-parameter family of 2-qudit PPT entangled states which generalizes the celebrated Horodecki state in 3 x 3. The entanglement of this family is identified via semidefinite programming based on "PPT symmetric ...
-
(Cambridge University Press, 2019-09-07)Cosmological simulations are a powerful tool to test various cosmological and galaxy formation scenarios. The discovery of low surface brightness objects has been a challenge for both of these fields. Our work aims to ...
