Article
The multiconfiguration Dirac-Hartree-Fock method is employed to calculate the continuum electron wave functions, which are then used to estimate their contribution to the atomic electric dipole moment (EDM) of Xe129. The EDM arises from (P,T)-odd electron-nucleon tensor-pseudotensor and pseudoscalar-scalar interactions, the nuclear Schiff moment, t...

Ag-based plasmonic nanostructures were manufactured by thermal annealing of thin metallic films. Structure and morphology were studied using scanning electron microscopy (SEM), transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HR-TEM) and X-ray photoelectron spectroscopy (XPS). SEM images show that the format...

For the first time the differential cross sections of the elastic scattering of slow electrons from argon atoms are calculated in a relativistic multiconfiguration method. The correlation effects responsible for target polarization are treated in a relativistic configuration–interaction scheme that allows for dynamical effects. Calculations of the...

Plasmonic platforms based on Au nanostructures have been successfully synthesized by directional solidification of a eutectic from Au and the substrate. In order to determine homogeneous shape and space distribution, the influence of annealing conditions and the initial thickness of the Au film on the nanostructures was analyzed. For the surface mo...

The contribution of exchange interactions is investigated for spin polarization of electrons which are scattered elastically from xenon and mercury at the energy of 1.5 eV. We find that electron exchange between the bound-state and the scattered electron gives rise to a substantial spin polarization in both cases.

Renal tumor malignancy classification is one of the crucial tasks in urology, being a primary factor included in the decision of whether to perform kidney removal surgery (nephrectomy) or not. Currently, tumor malig-nancy prediction is determined by the radiological diagnosis based on computed tomography (CT) images. However, it is estimated that u...
Article
Plasmonic nanostructures based on AuAg nanoalloys were fabricated by thermal annealing of metallic films in an argon atmosphere. The nanoalloys were chosen because they can extend the wavelength range in which plasmon resonance occurs and thus allow the design of plasmonic platforms with the desired parameters. The influence of initial fabrication...

The purpose of the current study was to examine the cortical correlates of imagery depending on instructional modality (guided vs. self-produced) using various sports-related scripts. According to the expert-performance approach, we took an idiosyncratic perspective analyzing the mental imagery of an experienced two-time Olympic athlete to verify w...

MIDAS (Medical Image Dataset Annotation Service) is a custom-tailored tool for creating and managing datasets either for deep learning, as well as machine learning or any form of statistical research. The aim of the project is to provide one-fit-all platform for creating medical image datasets that could easily blend in hospital's workflow. In our...

TeO2-BaO-Bi2O3-Ag glass systems (TBB) co-doped with terbium and europium ions have been successfully synthesized through conventional melt-quenching technique. Heat treatment procedure at 350 °C has been conducted in order to synthesize silver nanoparticles embedded in TBB glass matrix. Structural measurements involved XRD studies that revealed no...
Article
Only a few of learning aids and simulations of physical phenomena allow for building interactive experiments; experiments similar to those that should be conducted in physics laboratories at schools. Group of staff from Gdansk University of Technology decided to fill this market niche by designing and constructing a set of virtual experiments – so...
Article
In this contribution we describe the multichannel extension to the nonrelativistic J-matrix method, and present differential cross sections for scattering of slow electrons from Argon atoms. Nonrelativistic phase shifts, then the S-matrix and the cross sections have been calculated using newly developed Fortran code, JMATRIX-MULTI. We applied the m...

We present a convergence study of the relativistic J-matrix method, applied to elastic scattering of electrons on the various model potentials vanishing faster than Coulomb one. Calculations have been performed using newly developed JMATRIX code. The code have been used to calculate phase shifts for a wide range of energies and to obtain total, dif...
Conference Paper
One can find many learning aids and simulations of physical phenomena on the market - provided as a standalone application or as part of an educational package. However, only a few of them allow for the building of interactive experiments: experiments similar to those that should be conducted in physics laboratories at schools. Gdańsk University of...
Article
It seems that nowadays schools do not keep up with the times. Recent studies have highlighted that students' needs are not being met and they are not prepared well enough for future study and/or work. The lack of the possibility to conduct their own experiments (e.g. physics experiments similar to those that should be conducted in physics laborator...

Ab initio relativistic calculations have been carried out to search for critical minima in the angle and energy differential cross-sections for the elastic scattering of electrons from argon and zinc atoms. Theoretical approach is based on the Dirac–Hartree–Fock method. Exchange between incident and target electrons is calculated exactly. Target po...

Relativistic ab initio calculations of both low- and high-angle critical minima in the differential cross sections are presented. The theoretical approach is based on the Dirac-Hartree-Fock method. Exchange between incident and target electrons is calculated exactly. Target polarization is described by ab initio potential taken from relativistic po...
