    Influence of hadronic interaction models and the cosmic ray spectrum on the high energy atmospheric muon and neutrino flux

    Get PDF
    The recent observations of muon charge ratio up to about 10 TeV and of atmospheric neutrinos up to energies of about 400 TeV has triggered a renewed interest into the high-energy interaction models and cosmic ray primary composition. A reviewed calculation of lepton spectra produced in cosmic-ray induced extensive air showers is carried out with a primary cosmic-ray spectrum that fits the latest direct measurements below the knee. In order to achieve this, we used a full Monte Carlo method to derive the inclusive differential spectra (yields) of muons, muon neutrinos and electron neutrinos at the surface for energies between 80 GeV and hundreds of PeV. The air shower simulator {\sc corsika} 6.990 was used for showering and propagation of the secondary particles through the atmosphere, employing the established high-energy hadronic interaction models {\sc sibyll} 2.1, {\sc qgsjet-01} and {\sc qgsjet-ii 03}. We show that the performance of the interaction models allows makes it possible to predict the spectra within experimental uncertainties, while {\sc sibyll} generally yields a higher flux at the surface than the qgsjet models. The calculation of the flavor and charge ratios has lead to inconsistent results, mainly influenced by the different representations of the K/π\pi ratio within the models. Furthermore, we could quantify systematic uncertainties of atmospheric muon- and neutrino fluxes, associated to the models of the primary cosmic-ray spectrum and the interaction models. For most recent parametrizations of the cosmic-ray primary spectrum, atmospheric muons can be determined with an uncertainty smaller than 13+15^{+15}_{-13}% of the average flux. Uncertainties of the muon- and electron neutrino fluxes can be calculated within an average error of 22+32^{+32}_{-22}% and 19+25^{+25}_{-19}%, respectively.Comment: 16 pages, 10 figures, version 2 includes analytic approximatio

    Objective: to investigate the specific features of epilepsy that manifests itself in the presence of chronic cerebrovascular disease.Patients and methods. A total of 304 patients (a study group of 174 patients with new-onset seizures developing in the presence of cerebrovascular disease and a control group of 130 patients with cerebrovascular disease and no seizures) were examined. They underwent clinical neurological examination, electroencephalography (EEG), ultrasonic duplex scanning of extra- and intracranial arteries with functional tests, and visualization of brain structures.Results. Focal seizures were prevalent in the patients with cerebrovascular disease and epilepsy. It was found that there was a preponderance of left-sided localization of EEG foci of abnormal activity and a tendency to more commonly detect subcritical and critical stenoses in the left carotid bed in the patients with epileptic seizures. Diminished perfusion reserves in the posterior circulation system were more frequently observed in the patients with seizures in the presence of cardiovascular diseases. Moreover, the patients with seizures displayed a more profound degree of brain ischemia with the frequent cortical and subcortical localization of dyscirculatory foci. Thus, a study of perfusion reserves, localization of vascular foci, and degree of occlusive changes in the wall of brachiocephalic vessels allows identification of risk factors for epilepsy in the patients with cerebrovascular disease and promotes the prediction of the course of the disease

    An extensive simulation has been carried out to estimate the physical interpretation of dynamical factors such as , in terms of high energy interaction features, concentrated in the present analysis on the average transverse momentum. It appears that the large enhancement observed for versus primary energy, suggesting in earliest analysis a significant rise of with energy, is only the result of the limited resolution of the detectors and remains in agreement with a wide range of models used in simulations.Comment: 13 pages, 6 PostScript figures, LaTeX Subm. to JPhys

    Based on hypotheses concerning the role of stress in acute pancreatitis development, the experimental approach for the decrease stress damage via the use the compound with proven antistress/neuroleptic action was conducted. The study was aimed to discover 2-morpholino-5-phenyl-6H-1,3,4-thiadiazine hydrobromide (compound L-17) therapeutic action in experimental acute pancreatitis. The experimental model used was the ligation model. The trial was carried out on 50 male Wistar rats with average body weight 180-240g. Histological picture of the pancreas was studied and biochemical and enzyme-immunoassays were carried out on the first and seventh days. The significant reduction in mortality on the background of L-17 compound administration was observed. While levels of all cytokines increased in induced experimental acute pancreatitis groups, the cytokine level rise was decreased when compound L-17 was administered. On the cellular level, the study revealed L-17’s ability to prevent granulocytosis and decrease granulocytes infiltration to inflammatory foci. The decrease in inflammatory reaction magnitude and prevention of abscess formation in experimental acute pancreatitis accompanied by sistemic inflamamtion was due to L-17’s ability to reduce neutrophilia and neutrophil entry into the injury zone. © 2018, Slovak Academy of Sciences.
