1. "I've always spoke like this, you see" : preterite-to-participle leveling in American and British EnglishesAlicia Chatten, Kimberley Baxter, Erwanne Mas, Jailyn Peña, Guy Tabachnick, Daniel Duncan, Laurel MacKenzie, 2024, izvirni znanstveni članek Opis: Some English verbs use distinct forms for the preterite (i.e., simple past; e.g., I broke the door) and the past participle (e.g., I’ve broken the door). These verbs may variably show use of the preterite form in place of the participle (e.g., I’ve broke the door), which the authors call participle leveling. This article contributes the first detailed variationist study of participle leveling by investigating the phenomenon in perfect constructions using data collected from three corpora of conversational speech: two of American English and one of British English. A striking degree of similarity is found between the three corpora in both the linguistic and the extralinguistic constraints on variation. Constraints on participle leveling include tense of the perfect construction, verb frequency, and phonological similarity between preterite and participle forms. The variable is stable in real time and socially stratified. The article relates the findings to theoretical linguistic treatments of the variation and to questions of its origin and spread in Englishes transatlantically.

4. The Cherenkov Telescope ArrayDaniel Mazin, Christopher Eckner, Gašper Kukec Mezek, Samo Stanič, Serguei Vorobiov, Lili Yang, Gabrijela Zaharijas, Danilo Zavrtanik, Marko Zavrtanik, Lukas Zehrer, 2019, objavljeni znanstveni prispevek na konferenci Opis: The Cherenkov Telescope Array (CTA) is the next generation ground-based observatory
for gamma-ray astronomy at very-high energies. It will be capable of detecting gamma rays in the energy range from 20 GeV to more than 300 TeV with unprecedented precision in energy and directional reconstruction. With more than 100 telescopes of three different types it will be located in the northern hemisphere at La Palma, Spain, and in the southern
at Paranal, Chile. CTA will be one of the largest astronomical infrastructures in the world with open data access and it will address questions in astronomy, astrophysics and fundamental physics in the next decades. In this presentation we will focus on the status
of the CTA construction, the status of the telescope prototypes and highlight some of the physics perspectives.

6. A dual-wavelength photothermal aerosol absorption monitor : design, calibration and performanceLuka Drinovec, Uroš Jagodič, Luka Pirker, Miha Škarabot, Mario Kurtjak, Kristijan Vidović, Luca Ferrero, Bradley Visser, Jannis Röhrbein, Ernest Weingartner, Daniel M. Kalbermatter, Konstantina Vasilatou, Griša Močnik, 2022, izvirni znanstveni članek Opis: There exists a lack of aerosol absorption measurement techniques with low uncertainties and without artefacts. We have developed the two-wavelength Photothermal Aerosol Absorption Monitor (PTAAM-2λ), which measures the aerosol absorption coefficient at 532 and 1064 nm. Here we describe its design, calibration and mode of operation and evaluate its applicability, limits and uncertainties. The 532 nm channel was calibrated with ∼ 1 µmol mol−1 NO2, whereas the 1064 nm channel was calibrated using measured size distribution spectra of nigrosin particles and a Mie calculation. Since the aerosolized nigrosin used for calibration was dry, we determined the imaginary part of the refractive index of nigrosin from the absorbance measurements on solid thin film samples. The obtained refractive index differed considerably from the one determined using aqueous nigrosin solution. PTAAM-2λ has no scattering artefact and features very low uncertainties: 4 % and 6 % for the absorption coefficient at 532 and 1064 nm, respectively, and 9 % for the absorption Ångström exponent. The artefact-free nature of the measurement method allowed us to investigate the artefacts of filter photometers. Both the Aethalometer AE33 and CLAP suffer from cross-sensitivity to scattering – this scattering artefact is most pronounced for particles smaller than 70 nm. We observed a strong dependence of the filter multiple scattering parameter on the particle size in the 100–500 nm range. The results from the winter ambient campaign in Ljubljana showed similar multiple scattering parameter values for ambient aerosols and laboratory experiments. The spectral dependence of this parameter resulted in AE33 reporting the absorption Ångström exponent for different soot samples with values biased 0.23–0.35 higher than the PTAAM-2λ measurement. Photothermal interferometry is a promising method for reference aerosol absorption measurements.

7. Comparing black-carbon- and aerosol-absorption-measuring instruments – a new system using lab-generated soot coated with controlled amounts of secondary organic matterDaniel M. Kalbermatter, Griša Močnik, Luka Drinovec, Bradley Visser, Jannis Röhrbein, Matthias Oscity, Ernest Weingartner, Antti-Pekka Hyvärinen, Konstantina Vasilatou, 2022, izvirni znanstveni članek Opis: We report on an inter-comparison of black-carbon- and aerosol-absorption-measuring instruments with laboratory-generated soot particles coated with controlled amounts of secondary organic matter (SOM). The aerosol generation setup consisted of a miniCAST 5201 Type BC burner for the generation of soot particles and a new automated oxidation flow reactor based on the micro smog chamber (MSC) for the generation of SOM from the ozonolysis of α-pinene. A series of test aerosols was generated with elemental to total carbon (EC TC) mass fraction ranging from about 90 % down to 10 % and single-scattering albedo (SSA at 637 nm) from almost 0 to about 0.7. A dual-spot Aethalometer AE33, a photoacoustic extinctiometer (PAX, 870 nm), a multi-angle absorption photometer (MAAP), a prototype photoacoustic instrument, and two prototype photo-thermal interferometers (PTAAM-2λ and MSPTI) were exposed to the test aerosols in parallel. Significant deviations in the response of the instruments were observed depending on the amount of secondary organic coating. We believe that the setup and methodology described in this study can easily be standardised and provide a straightforward and reproducible procedure for the inter-comparison and characterisation of both filter-based and in situ black-carbon-measuring (BC-measuring) instruments based on realistic test aerosols.

9. Temporal and spatial patterns of zinc and iron accumulation during barley (Hordeum vulgare L.) grain development. Journal of agricultural and food chemistry.Amelie Detterbeck, Paula Pongrac, Daniel Persson, Katarina Vogel-Mikuš, Mitja Kelemen, Primož Vaupetič, Primož Pelicon, Iztok Arčon, Søren Husted, Jan Kofod Shjoerring, Stephan Clemens, 2020, izvirni znanstveni članek Opis: Breeding and engineering of biofortified crops will benefit from a better understanding of bottlenecks controlling
micronutrient loading within the seeds. However, few studies have addressed the changes in micronutrient concentrations,
localization, and speciation occurring over time. Therefore, we studied spatial patterns of zinc and iron accumulation during grain
development in two barley lines with contrasting grain zinc concentrations. Microparticle-induced-X-ray emission and laser ablationinductively
coupled plasma mass spectrometry were used to determine tissue-specific accumulation of zinc, iron, phosphorus, and
sulfur. Differences in zinc accumulation between the lines were most evident in the endosperm and aleurone. A gradual decrease in
zinc concentrations from the aleurone to the underlying endosperm was observed, while iron and phosphorus concentrations
decreased sharply. Iron co-localized with phosphorus in the aleurone, whereas zinc co-localized with sulfur in the sub-aleurone. We
hypothesize that differences in grain zinc are largely explained by the endosperm storage capacity. Engineering attempts should be
targeted accordingly.
