Magnetic quantum criticality in quasi-one-dimensional Heisenberg antiferromagnet Cu(C4H4N2)(NO3)2
2016
We analyze exciting recent measurements [Phys. Rev. Lett. 114 (2015) 037202] of the magnetization, differential susceptibility and specific heat on one dimensional Heisenberg antiferromagnet Cu(C4H4N2)(NO3)2 (CuPzN) subjected to strong magnetic fields. Using the mapping between magnons (bosons) in CuPzN and fermions, we demonstrate that magnetic field tunes the insulator towards quantum critical point related to so-called fermion condensation quantum phase transition (FCQPT) at which the resulting fermion effective mass diverges kinematically. We show that the FCQPT concept permits to reveal the scaling behavior of thermodynamic characteristics, describe the experimental results quantitativ…
Drug-Coated Balloon vs. Stent for de novo Non-small Coronary Artery Disease: A Systematic Review and Meta-Analysis
2021
Introduction: Drug-coated balloon (DCB) has been an attractive option in de novo vessels. A systematic review and meta-analysis were conducted to evaluate the efficacy and safety of DCB vs. stent for treating de novo lesions in non-small vessels.Methods: Studies in PubMed, Embase, the Cochrane Central Register of Controlled Trials, and Web of Science were searched (from their commencement to March 2021). This meta-analysis was performed by Review Manager 5.3.Results: A total of 3 random controlled trials (RCTs) with 255 patients and 2 observational studies (OS) with 265 patients were included in this meta-analysis following our inclusion criteria. It could be observed that DCB presented no …

Model społeczeństwa a założenia Specjalnej Strefy Demograficznej
2016
Założenia opolskiej Specjalnej Strefy Demograficznej odwołują się do strukturalno-systemowych teorii społeczeństwa. Stan katastrofy demograficznej wymaga, moim zdaniem, przeprowadzenia reprezentatywnych badań empirycznych wśród młodego pokolenia, opracowania socjologicznego studium i uzupełnienia teoretycznych założeń Specjalnej Strefy Demograficznej w regionie opolskim.
Noziedzīgi iegūtas mantas atgūšanas problemātika
2016
Noziedzīgi iegūtas mantas atgūšana ir vairāku savstarpēji saistītu procesu kopums, kā rezultātā noziedzīgi iegūta manta tiek konfiscēta vai atgriezta likumīgajam īpašniekam. Atgūšanas procesi ir: noziedzīgi iegūtās mantas identificēšana, arests, pierādījumu iegūšana mantas noziedzīgajai izcelsmei, kas ietver arī starptautisko sadarbību, un galējā nolēmuma par mantu pieņemšana. Veiksmīgai noziedzīgi iegūtas mantas atgūšanai nepieciešama visu iepriekš minēto procesu nekļūdīga norise un valsts ieinteresētība izveidot tādus politikas plānošanas dokumentus un tiesisko regulējumu, lai uzlabotu noziedzīgi iegūtas mantas atgūšanas procesus. Pētījuma mērķis bija izpētīt noziedzīgi iegūtas mantas atg…
Noziedzīgi iegūtu līdzekļu legalizēšana- pastāvošās problēmas, iespējamie risinājumi
2019
Noziedzīgi iegūtu līdzekļu legalizēšana ir noziegums, kas paredzēts Krimināllikuma 195.pantā, papildus tam, šī nozieguma apkarošanai ir ticis pieņemts arī atsevišķs likums, tieši Noziedzīgi iegūtu līdzekļu legalizēšanas un terorisma finansēšanas novēršanas likums. Neskatoties uz to, ka šo vienu noziegumu regulē ļoti plašs un izvērsts regulējums, tā apkarošana gan Latvijā, gan pasaulē ir bijusi ļoti neefektīva visā tā pastāvēšanas laikā. Tieši tāpēc šī Bakalaura darba mērķis ir noteikt problēmas kādas pastāv atklājot, izmeklējot un notiesājot personas noziedzīgi iegūtu līdzekļu legalizēšanas gadījumos, lai pēc tam varētu piedāvāt konkrētus risinājumus šo problēmu turpmākai novēršanai. Lai sa…
Spectroscopy of 70Kr and isospin symmetry in the T = 1 f pg shell nuclei
2016
International audience; The recoil-β tagging technique has been used in conjunction with the 40 Ca(32 S ,2n) reaction at a beam energy of 88 MeV to identify transitions associated with the decay of the 2 + and, tentatively, 4 + states in the nucleus 70 Kr. These data are used, along with previously published data, to examine the triplet energy differences (TED) for the mass 70 isobars. The experimental TED values are compared with shell model calculations, performed with the JUN45 interaction in the fpg model space, that include a J = 0 isospin nonconserving (INC) interaction with an isotensor strength of 100 keV. The agreement is found to be very good up to spin 4 and supports the expectat…
First candidates for γ vibrational bands built on the [505]11/2⁻ neutron orbital in odd-A Dy isotopes
2020
Rotational structures have been measured using the Jurogam II and GAMMASPHERE arrays at low spin following the 155Gd(α,2n)157Dy and 148Nd(12C,5n)155Dy reactions at 25 and 65 MeV, respectively. We report high-K bands, which are conjectured to be the first candidates of a Kπ=2+γ vibrational band, built on the [505]11/2− neutron orbital, in both odd-A155,157Dy isotopes. The coupling of the first excited K=0+ states or the so-called β vibrational bands at 661 and 676 keV in 154Dy and 156Dy to the [505]11/2− orbital, to produce a Kπ=11/2− band, was not observed in both 155Dy and 157Dy, respectively. The implication of these findings on the interpretation of the first excited 0+ states in the cor…
Octupole states in 207Tl studied through β decay
2020
The β decay of 207Hg into the single-proton-hole nucleus 207Tl has been studied through γ-ray spectroscopy at the ISOLDE Decay Station (IDS) with the aim of identifying states resulting from coupling of the πs−11/2, πd−13/2, and πh−111/2 shell model orbitals to the collective octupole vibration. Twenty-two states were observed lying between 2.6 and 4.0 MeV, eleven of which were observed for the first time, and 78 new transitions were placed. Two octupole states (s1/2-coupled) are identified and three more states (d3/2-coupled) are tentatively assigned using spin-parity inferences, while further h11/2-coupled states may also have been observed for the first time. Comparisons are made with st…
