325. Podatkovna baza WeSoSlaV kot izhodišče za preučevanje slovenskih glagolov : predavanje na Mednarodnem dnevu slovarjev 2023, Slovarji na obronkih našega prostora, časa in družbe, 16. 10. 2023Petra Mišmaš, Franc Marušič, Rok Žaucer, 2023, unpublished conference contribution Abstract: Pomen besedilnih korpusov za slovaropisje in jezikovne raziskave je v zadnjem času postal zelo očiten. Hkrati pa se zasledi tudi mnenje, da so potrebe po korpusih zadoščene s čim večjim splošnim korpusom tipa Gigafida 2.0 in s še kakšnim specializiranim korpusom spletnih besedil (npr. slWaC, JANES), besedil določenega zgodovinskega obdobja (npr. Korpus 16), govorjenih besedil (npr. GoS), šolskih besedil (npr. Šolar) ipd. V prispevku bomo predstavili primer podatkovne baze, ki je nastala zaradi specifičnih raziskovalnih potreb, ki jih omenjeni korpusi ne morejo zadostiti.
V bazi glagolov zahodnih južnoslovanskih jezikov WeSoSlaV (Western South Slavic Verbs) sta združeni podatkovna baza slovenskih glagolov in podatkovna baza, ki združuje glagole iz bosanščine, črnogorščine, hrvaščine in srbščine (BČHS). Za vsak navedeni jezik je v bazo vključenih po tri tisoč glagolov, pri čemer končno število glagolov za BČHS zaradi podvajanja glagolov med različicami BČHS ni 12.000 temveč 5.300. Do septembra 2023 sta v spletnem repozitoriju Slovenske raziskovalne infrastrukture za jezikovne vire in tehnologije CLARIN.SI objavljena dva dela baze WeSoSlaV, in sicer Database of the Western South Slavic Verb HyperVerb 1.0 (Marušič idr. 2022), ki je namenjen oblikoslovnim lastnostim glagolov, ter Database of the Western South Slavic Verb HyperVerb - Derivation (Milosavljević idr. 2023), v kateri so opisane besedotvorne lastnosti glagolov.
V prispevku se omejujemo na slovenski del baze WeSoSlaV. Predstavljen bo postopek anotacije lastnosti glagolov (lastnosti, kot so naglas, tematski vokali, predpone itd.), težave, ki so se pojavljale pri označevanju (npr. test za nedovršnost), in primer uporabe podatkov, zbranih v bazi.

327. The Cherenkov Telescope Array. Science Goals and Current StatusRene A. Ong, Christopher Eckner, Gašper Kukec Mezek, Samo Stanič, Serguei Vorobiov, Lili Yang, Gabrijela Zaharijas, Danilo Zavrtanik, Marko Zavrtanik, Lukas Zehrer, 2019, published scientific conference contribution (invited lecture) Abstract: The Cherenkov Telescope Array (CTA) is the major ground-based gamma-ray observatory planned for the next decade and beyond. Consisting of two large atmospheric Cherenkov telescope arrays (one in the southern hemisphere and one in the northern
hemisphere), CTA will have superior angular resolution, a much wider energy range, and
approximately an order of magnitude improvement in sensitivity, as compared to existing instruments. The CTA science programme will be rich and diverse, covering cosmic particle acceleration, the astrophysics of extreme environments, and physics frontiers beyond the Standard Model. This paper outlines the science goals for CTA and covers the current status of the project.
Keywords: very-high-energy gamma-ray astronomy, Cherenkov Telescope Array (CTA), cosmic particle acceleration, astrophysics of extreme environments, physics beyond the Standard Model

328. Ultrahigh-Energy multi-messengers at the Pierre Auger ObservatoryFrancisco Pedreira, Andrej Filipčič, Gašper Kukec Mezec, Ahmed Saleh, Samo Stanič, Marta Trini, Serguei Vorobiov, Lili Yang, Danilo Zavrtanik, Marko Zavrtanik, Lukas Zehrer, 2019, published scientific conference contribution Abstract: The study of correlations between observations of different messengers from extreme sources of the Universe has emerged as an outstanding way to make progress in astrophysics. The Pierre Auger Observatory is capable of significant contributions as an ultra-high energy particle detector, particularly through its capability to search for inclined showers produced by neutrinos. We describe the neutrino searches made with
the Observatory with particular emphasis on the recent results following the detections of
gravitational waves from binary mergers with Advanced LIGO and VIRGO, leading to competitive limits.

329. Studies of the UHECR Mass Composition and Hadronic Interactions with the FD and SD of the Pierre Auger ObservatoryJ.M. Carceller, Andrej Filipčič, Gašper Kukec Mezek, Ahmed Saleh, Samo Stanič, Marta Trini, Serguei Vorobiov, Lili Yang, Danilo Zavrtanik, Marko Zavrtanik, Lukas Zehrer, 2019, published scientific conference contribution Abstract: With data on the depth of maximum Xmax collected during more than a decade of operation of the Pierre Auger Observatory, we report on the inferences on the mass composition of UHECRs in the energy range E = 10[sup]17.2 − 10[sup]19.6 eV and on the measurements of the proton-air cross section for energies up to 10[sup]18.5 eV. We also present the results on Xmax obtained using the information on the particle arrival times recorded by the SD stations allowing us to extend the Xmax measurements up to 10[sup]20 eV. The inferences on mass composition, in particular using the data of the SD, are subject to systematic uncertainties
due to uncertainties in the description of hadronic interactions at ultra-high energies. We
discuss this problem with respect to the properties of the muonic component of extensive
air-showers as derived from the SD data.
Keywords: ultra-high-energy cosmic rays (UHECRs), extensive air showers (EAS), EAS muonic component, EAS electromagnetic component, Pierre Auger Observatory, UHECR mass composition, UHECR hadronic interactions

330. Measurement of the cosmic ray spectrum with the Pierre Auger ObservatoryDaniela Mockler, Andrej Filipčič, Gašper Kukec Mezek, Ahmed Saleh, Samo Stanič, Marta Trini, Serguei Vorobiov, Lili Yang, Danilo Zavrtanik, Marko Zavrtanik, Lukas Zehrer, 2019, published scientific conference contribution Abstract: The flux of ultra-high energy cosmic rays above 3×10[sup]17 eV has been measured with unprecedented precision at the Pierre Auger Observatory. The flux of the cosmic rays is determined by four different measurements. The surface detector array provides three data sets, two formed by dividing the data into two zenith angle ranges, and one obtained from a nested, denser detector array. The fourth measurement is obtained with the fluorescence detector. By combining all four data sets, the all-sky flux of cosmic rays is determined. The spectral features are discussed in detail and systematic uncertainties are addressed.
Keywords: ultra-high-energy cosmic rays (UHECRs), Pierre Auger Observatory, UHECR energy spectrum
