Analysis of the mass composition of highenergy cosmic ray
(IOP Publishing, 2013)This paper analyses mass composition of highenergy cosmic ray, comparing simulation and experimental results. Using the nuclear interaction models QGSJETII and Sibyll, we simulate EAS initiated by the primary nuclei ... 
Wigner functions and coherent states for the quantum mechanics on a circle
(IOP Publishing, 2021)The Wigner functions for the coherent states of a particle on a circle are discussed. The nontrivial analytic forms of these functions are derived. The classicality of the circular coherent states existing in the literature ... 
Artificial Neural Network as a FPGA Trigger for a Detection of NeutrinoInduced Air Showers
(IntechOpen, 2016)Neutrinos play a fundamental role in the understanding of the origin of ultrahighenergy cosmic rays (UHECR). They interact through charged and neutral currents in the atmosphere generating extensive air showers. However, ... 
Lorentzcovariant, unitary evolution of a relativistic Majorana qubit
(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 fourmomentum as an external ... 
An analysis method for data taken by Imaging Air Cherenkov Telescopes at very high energies under the presence of clouds
(Elsevier, 2020)The effective observation time of Imaging Air Cherenkov Telescopes (IACTs) plays an important role in the detection of γray sources, especially when the expected flux is low. This time is strongly limited by the atmospheric ... 
An Extremum Principle for Smooth Problems
(MDPI, 2020)We derive an extremum principle. It can be treated as an intermediate result between the celebrated smoothconvex extremum principle due to Ioffe and Tikhomirov and the Dubovitskii–Milyutin theorem. The proof of this ... 
The covariance of chiral fermions theory
(Springer Nature, 2019)The quasiclassical theory of massless chiral fermions is considered. The effective action is derived using timedependent variational principle which provides a clear interpretation of relevant canonical variables. As a ... 
The Carbon Footprint Methodology in CFOOD Project
(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 lowcarbon products is presented. The optimization process and limits were analyzed based on the CFOOD project cofinanced by ... 
SurfaceBound and Volatile Mo Oxides Produced During Oxidation of Single MoS2 Crystals in Air and High Relative Humidity
(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, ... 
Measurementinduced geometric measures of correlations based on the trace distance for twoqubit X states
(Springer Nature, 2020)We apply the modified Brodutch and Modi method of constructing geometric measures of correlations to obtain analytical expressions for measurementinduced geometric classical and quantum correlations based on the trace ... 
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 ... 
Multiobjective optimization of vehicle routing problem using evolutionary algorithm with memory
(AGH Publishing House, 2017)The idea of a new evolutionary algorithm with memory aspect included is proposed to find multiobjective optimized solution of vehicle routing problem with time windows. This algorithm uses population of agents that ... 
Absorption effects in the blazar’s γray spectra due to luminous stars crossing the jet
(Royal Astronomical Society, 2021)γray emission in active galaxies is likely produced within the inner jet, or in the close vicinity of the supermassive black hole (SMBH) at subparsec distances. γrays have to pass through the surrounding massive stellar ...

Anti‑algal activity of the 12‑5‑12 gemini surfactant results from its impact on the photosynthetic apparatus
(Springer Nature, 2021)A rapid amplification of algal population has a negative impact on the environment and the global economy. Thus, control of algal proliferation is an important issue and effective procedures which reduce algal blooms and ... 
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, singlevalued and continuous functions. The basic sets of ...
