Superaktywacja nierówności Svetlichnego w układach wielocząstkowych
(2017)Rozprawa doktorska obejmuje analizę aktywacji łamania nierówności Svetlichnego w układach trzycząstkowych zarówno dla stanów czystych jak i dla mieszanych stanów zaszumionych. W ostatnich latach nielokalne korelacje ... -
X-ray/γ-ray Correlation in Seyfert 2 Galaxy NGC 4945
(AIP Conference Proceedings - American Institute of Physics, 2017-01-04)We report the correlation between the X-ray and γ-ray emission found in our analysis of the Fermi/LAT and Swift/BAT data from 8 years of observations of the nearby Seyfert 2 galaxy NGC 4945. Using the BAT light-curves we ... -
Modelling of the non-thermal emission from inhomogeneous jets in active galactic nuclei
(2018)Some active galactic nuclei (AGNs) are strong sources of non-thermal radiation. It is expected that this radiation is produced in collimated outflows of plasma moving with relativistic speeds, the so-called jets. The ... -
Method for Generating of Archimedean Triangular Connective Operators
(Łódzkie Towarzystwo Naukowe, 2018)Archimedean triangular operators form the basis of the tools for development, analysis and designing of fuzzy systems. They are generated by simple, monotone, single-valued and continuous functions. The basic sets of ... -
Electrocaloric effect in cubic Hubbard nanoclusters
Balcerzak, Tadeusz
; (Springer Nature, 2018)
In the paper a computational study of the electrocaloric efect is presented for a cubic nanocluster consisting of 8 sites. The system of interest is described by means of an extended Hubbard model in external electric ... -
Lorentz-covariant, unitary evolution of a relativistic Majorana qubit
Smoliński, Kordian; ; ; (Springer Nature, 2018)
We formulate a covariant description of a relativistic qubit identified with an irreducible set of quantum spin states of a Majorana particle with a sharp momentum. We treat the particle’s four-momentum as an external ... -
Badanie i optymalizacja wpływu procedur wytwarzania i iniekcji 18F-FDG na poziom narażenia personelu placówek produkujących radiofarmaceutyki na bazie izotopów krótkożyciowych
Albiniak, Łukasz (2018)
Lista izotopów promieniotwórczych znajdujących swoje zastosowanie w medycynie nuklearnej jest długa, a pierwsze miejsce niepodzielnie należy do izotopu 99mTc – uzyskiwanego w generatorze 99Mo/99mTc. Drugą pozycję według ... -
High-energy radiation from low-luminosity accreting black holes
(2018)This PhD thesis includes theoretical and observational studies of γ-ray emission from radio-quiet accreting black holes. The theoretical motivation for the search of γ-ray emission from such sources concerns the considerable ... -
A need for eye lens dosimetry in nuclear medicine
Wrzesień, Małgorzata; ; ; (Sievert Association, 2019)
Background: Changing the individual dose limit for the lens of the eye from a value of 150 mSv per year to a level of 20 mSv (averaged over defined periods of five years or 50 mSv in a single year) means that issues related ... -
Noise resistance of activation of the violation of the Svetlichny inequality
(Springer Nature, 2019)In this paper, we analyze the activation of the violation of the Svetlichny inequality in GHZ states in the presence of noise. We take into account bit flip, phase flip, amplitude damping and depolarizing noisy channels ... -
The covariance of chiral fermions theory
Gonera, Cezary; ; ; Gonera, Joanna ; Kosinski, Piotr ; (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 ... -
Study on the application of phototransferred thermoluminescence to reassessment of radiation dose using MCP-N and MTS-N detectors
(2019)The topic of a dissertation is to examine the impact of UV and thermal stimulation on the emission of thermoluminescence light using the PTTL (PhotoTransferred ThermoLuminescence) phenomenon, and consequently – the search ... -

(2019)Praca dotyczy projektów dwóch innowacyjnych metod wytwarzania silnych pól magnetycznych. Pierwsza z tych metod to wykorzystanie paczek cząstek naładowanych, przyspieszonych przez akcelerator, do wytwarzania silnych pól ... -
Procesy hadronowe w dwutemperaturowych przepływach akrecyjnych
(2019)W rozprawie badam własności promieniste optycznie-cienkich, dwutemperaturowych przepływów akrecyjnych, które są szeroko rozważane jako wyjaśnienie obiektów z czarnymi dziurami o umiarkowanych i małych jasnościach. Uwzględniam ... -
Radiative neutron capture cross sections measurement of 70Ge at n_TOF CERN facility and its relevance for stellar nucleosynthesis
(2019)Stellar nucleosynthesis is the name given to the nuclear reactions taking place in stars to create the nuclei of the chemical elements. Elements heavier than iron/nickel are dominantly created by neutron capture reactions. ... -
Measurement-induced geometric measures of correlations based on the trace distance for two-qubit X states
Bauer, Jarosław; Walczak, Zbigniew (Springer Nature, 2020)
We apply the modified Brodutch and Modi method of constructing geometric measures of correlations to obtain analytical expressions for measurement-induced geometric classical and quantum correlations based on the trace ... -

Surface-Bound and Volatile Mo Oxides Produced During Oxidation of Single MoS2 Crystals in Air and High Relative Humidity
Dabrowski, Pawel; ; (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, ... -
