DATASET/RAW DATA for manuscript titled "ESTABLISHING DIAGNOSTIC REFERENCE LEVELS IN DIGITAL MAMMOGRAPHY UNITS IN THE REPUBLIC OF NORTH MACEDONIA"
(2025-01-13)

Mirjeta Mediji Arifi
The main objective of this study is to evaluate radiation exposure and establish a baseline for Diagnostic Reference Levels in digital mammography using the diagnostic and screening examination data from eight state-managed mammography imaging centres/units in the Republic of North Macedonia. Mean Glandular Dose (MGD) was studied from about 30000 images from about 8000 studied cases by digital mammography. Several factors and parameters were considered, such as anode/filter combination, left and right breast in two projections each (craniocaudal (CC), mediolateral oblique (MLO)), compressed breast thickness (CBT), the X-ray tube voltage in kVp, X-ray tube current-time product in mAs, and the compression force. The overall MGD for all examinations subject to this study obtained from CC and MLO projections from both breasts were evaluated to be 1.34 mGy and 1.61 mGy, respectively. Median MGDs, minimum, and maximum, were calculated to be 1.15 mGy, 0.1 mGy, and 9.93 mGy, respectively. The 75th percentile of the MGD for CC acquisitions increased from 0.94 mGy to 3.67 mGy with the increase of the CBT from 0 to 120 mm (step 10 mm). Likewise, the 75th percentile of MGD for MLO acquisitions, increased from from 0.44 mGy to 4.91 mGy, depending on the CBT. The obtained figures of MGD versus CBT for breast thicknesses between 30 and 75 mm for the eight mammography units were compared with the Acceptable European (ACC), Achievable European (ACH), Belgian diagnostic reference levels and MGDs reported for other countries/regions. The results showed that the mean MGD values of seven of the eight Mammography units examined in total appear to be lower than those of ACC, ACH, and Belgian reference values. Only the MGD calculated for one of the eight examined units appeared higher than the ACC.

Dataset for Polarization of Balmer alpha radiation resulting from H^++H collisions in Debye plasmas
(2015)
;
Janev, Ratko
The linear polarization degree of Balmer alpha radiation resulting from Hþ þ Hð1sÞ collisions in a hot, dense weakly coupled plasma is studied in the energy range 1–140keV=u by adopting the Debye-H€uckel potential to represent the screened interaction between charged plasma particles. Due to the energy splitting of nl hydrogen states in the short range Debye-Huckel potential, the Balmer alpha radiation contains three components corresponding to 3s-2p, 3p-2s, and 3d-2p transi- tions, of which only the last two can be linearly polarized. For calculation of 3lm excitation and electron capture cross sections, the two-center expansion atomic orbital close coupling method is used for a number of Debye screening lengths. The effects of plasma screening on the 3lm cross sections are manifested in significant changes of their magnitudes and energy behavior with respect to the ones in the unscreened case, producing significant changes in the polarization degree of Balmer 3p-2s and 3d-2p lines.

Dataset for Antiproton-impact ionization of hydrogen atom with Yukawa interaction
(2018)

Janev, Ratko
The process of ionization of hydrogen atom by antiproton impact is studied when the interparticle interactions in the system are described by screened interactions of Yukawa type. The collision dynamics is described by the semiclassical atomic-orbital close-coupling method in which the bound atomic states and positive energy continuum pseudostates are determined by diagonalization of target Hamiltonian in a sufficiently large even-tempered basis to ensure convergence of the results at each value of the screening length λ of the interaction. With decreasing the screening length, the bound states in the Yukawa potential become unbound, thus increasing the number of continuum pseudostates. At low collision energies, this leads to the increase of the ionization cross section. It is observed that the energies of pseudostates, generated by the exit of nl bound states in the continuum, at certain critical values λcnl exhibit series of avoided crossings when λ is varied. The avoided crossings appear between the (n + k)l and (n + k + 1)l (n =1, 2, 3, . . . ; k = 0, 1, 2, . . .) states at screening lengths close to the critical screening length λcnl . The avoided crossings become increasingly less pronounced with increasing n, k and l. The matrix elements for the (n + k)l − (n + k + 1)l transitions at the avoided crossings λ(n+k+1)l exhibit maxima and are reflected x,(n+k)l in the structure of the cross sections for population of the lower nl pseudostates. These structures are, however, smeared out in the total ionization cross section.

Dataset for land and elevation cover that can be used in propagation prediction and radio link and network performance over the territory of N.Macedonia.
(2022)
;
The files in the dataset contain the complete dataset for land and elevation cover that can be used in propagation prediction and radio link and network performance over the territory of N.Macedonia. In RF prediction a balance is required between calculation time and the accuracy. The number of records are the number of points between the TX and the RX unit that are taken in account in a simulation. More points will result in a higher accuracy and will take a long time to calculate. Less points will have a low accuracy but require a short calculation time. The provided dataset represent a compromise in this manner, when producing country-wide calculations.

Datasets for Electron capture, excitation and ionization processes in He2+–H collisions in dense quantum plasmas
(2018)
;
Ratko K. Janev
Electron capture, excitation and ionization processes in He2+–H collisions taking place in quan- tum plasmas are studied by employing the two-center atomic orbital close coupling (TC-AOCC) method. The Debye-Hu ̈ckel-cosine (DHC) potential is used to describe the plasma screening effects on the Coulomb interaction between charged particles. The properties of eigenenergies of hydrogen-like atom with DHC potential are investigated as function of the screening length of the potential. It is found that the bind- ing energies of nl states decrease with decreasing the screening length of the potential. The dynamics of excitation, electron capture and ionization processes in He2+–H collision system is investigated when the screening length of the potential varies for a wide collision energy range. The TC-AOCC cross sections are compared with those for the pure Coulomb potential and, for the total electron capture, with the results of classical trajectory Monte Carlo method.

The data files attached to this paper follows the information presented on the corresponding figures. Some of them contains additional data, regarding state energies and charge transfer sections to higher states, which were not presented in the published version of the paper due to page limitations. In addition to published charge exchange and excitation cross sections we provide unpublished data for direct ionization section, obtained with the adopted basis.
