Opis: Vipava valley in southwest Slovenia is a representative hot-spot for complex mixtures of different aerosol types of both anthropogenic and natural origin in mountainous terrain. An investigation of aerosol properties throughout the troposphere in different atmospheric conditions was made possible by a deployment of a two-wavelength polarization Raman lidar system combining with in-situ measurements in the valley (in the town of Ajdovščina) from September 2017. Using its aerosol identification capabilities, which are based on particle depolarization ratio and lidar ratio measurements, it was possible to identify predominant aerosol types in the observed atmospheric structures, for example in different atmospheric layers in the case of stratified atmosphere. Primary anthropogenic aerosols within the valley were found to be mainly emitted from two sources: individual domestic heating systems, which mostly use biomass fuel, and from traffic. A considerable fraction of natural aerosols (for example mineral dust and sea salt), transported over large distances, were observed both above and entering into the planetary boundary layer. According to the properties of different aerosol types, backscatter contribution of each aerosol type was evaluated and the corresponding extinction contribution was derived from lidar observations. Statistical analysis of the presence of different aerosol types was performed on the entire available dataset from 2017 and 2018.

The importance of not belonging: Paradigmaticity and loan nominalizations in Serbo-CroatianMarko Simonović
, Boban Arsenijević
, 2018, izvirni znanstveni članek
Opis: In a number of Slavic and Germanic languages, various derivational affixes and morphological patterns of Latin origin are relatively common, and bear effects as abstract as deriving event nouns from verbs and property nouns from adjectives. This seems to contradict the general observation that abstract morphology typically is not subject to borrowing. We discuss the status of two Serbo-Croatian (S-C) nominalizing Latinate suffixes, -cija and -itet, complemented by one Germanic suffix, -er. On our analysis, these are not borrowed suffixes and derivational patterns, in the sense that they were present in another language and got copied into S-C, but rather suffixes and patterns which emerged within S-C, more specifically in the borrowed stratum of the S-C lexicon. Crucial factors in their emergence were the shared semantic properties of the nouns ending in the respective sequences (-cija, -itet and -er), and the quantitative properties of these sequences closely matching those of native derivational suffixes. Pragmatic, phonological and prosodic constraints apply to these derivations to the effect that the suffixes that have emerged in the borrowed domain of the lexicon never enter a competition with the native nominalization patterns.

Exploring the Universe with supernovaeTanja Petrushevska
, objavljeni povzetek znanstvenega prispevka na konferenci (vabljeno predavanje)
Opis: Supernovae have proven to be exquisite tools for a variety of astrophysics and cosmology topics. In this lecture, I will highlight a selection of dedicated tele- scopic surveys for detecting supernovae and I will report some of our interesting discoveries during the past few years. I will dedicate special attention to strongly lensed supernovae by galaxies and galaxy clusters. Under the right circumstances, multiple images of the lensed supernovae can be observed, and due to the variable nature of the objects, the difference between the arrival times of the images can be measured. Since the images have taken different paths through space before reaching us, the time-differences are sensitive to the expansion rate of the universe. Therefore, measuring time delays from strongly lensed supernovae is emerging as a novel and independent tool for estimating the Hubble constant (H0). This is very important given the recent discord in the value of H0 from two methods that probe different distance ranges: the ESA mission Planck value corresponds to 67.74 ± 0.46 km s−1 Mpc−1; , while a reanalysis of the local distance scale gives 73.24 ± 1.74 km s−1 Mpc−1; [2, 3], these measurements thus being inconsistent at the ≈ 3.5σ level. Therefore, the results of additional independent and high- precision techniques, which rely on different physics, are of key importance. In this context, I will report our discovery of the first resolved multiply-imaged gra- vitationally lensed supernova Type Ia . Moving forward, I will discuss some of the prospects of upcoming facilities such as the Large Synoptic Survey Telescope and James Webb Space Telescope [5, 6].

Opis: Thin film technology has reached a maturity to achieve conversion efficiencies of the order of 22%. Among thin films, CdTe-based photovoltaic modules represent 80% of the total production. Nonetheless, some issues concerning back-contact are still open. In industrial process a chemical etching is required in order to make the CdTe film surface rich in Te. The Te-excess is fundamental in order to form a stable telluride compound with copper and to obtain an ohmic, low-resistance back-contact. Moreover, the Te-excess hinders the fast diffusion of copper in CdTe and its achievement of the junction region, preventing the destruction of the device. In this paper we study a ZnTe:Cu buffer layer deposited onto a CdTe film, characterized by a naturally Te-rich surface obtained with a particular chlorine heat treatment without any chemical etching. Copper diffusion and the CdTe/ZnTe:Cu interface were studied by x-ray

Opis: We report on orbital-dependent quasiparticle dynamics in EuFe 2 As 2, a parent compound of Fe-based superconductors, and a way to experimentally identify this behavior using time-and angle-resolved photoelectron spectroscopy across the spin density wave transition. We observe two different relaxation timescales for photoexcited d x z/d y z and d x y electrons. While the itinerant d x z/d y z electrons relax faster through the electron-electron scattering channel, d x y electrons form a quasiequilibrium state with the lattice due to their localized character, and the state decays slowly. Our findings suggest that electron correlation in Fe pnictides is an important property, which should carefully be taken into account when describing the electronic properties of both parent and carrier-doped compounds, and therefore establish a strong connection with cuprates

Prosody preservation and borrowing verbs as nouns in three systems with lexical prosodyMarko Simonović
, objavljeni povzetek znanstvenega prispevka na konferenci
Opis: The claim by Moravcsik (1975) that “if verbs are borrowed, they seem to be borrowed as if they were
nouns” generated a long-standing discussion within language contact research (see e.g. Wohlgemuth
2009 for a recent summary). More precisely, the claim was that “the borrowing language employs its
own means of denominal verbalization to turn the borrowed forms into verbs”. This can be interpreted
either as a statement about the integration pattern (which may not be mentally represented in
monolinguals) or as a claim about the syntactic representation of borrowed verbs in general, whereby
borrowed verbs contain an nP embedded under the vP. Both interpretations constitute important
hypotheses, which can serve as useful windows into the relation between morphology and phonology.
interpretation is compatible with the claim by Simonović (2015) that the integration pattern
essentially gets selected by Lexical Conservatism (Steriade 1997): the pattern with most preservation of
the properties of the base and least stem allomorphy integrates loanwords. The second interpretation
makes important predictions whose implementation is highly dependent on the theory of morphology
employed. In this presentation I use a recent elaboration of Distributed Morphology in which the
separation between roots and categorial heads is extended to derivational suxes
and put it to use in accounting for verb borrowing and denominal verbalisation in three Western South
Slavic varieties: Slovenian, Western Serbo-Croatian (henceforth Croatian) and Eastern Serbo-Croatian
(henceforth Serbian). All three varieties have lexical prosody. Slovenian has lexically determined stress.
In Serbo-Croatian each word has a lexically determined H, and stress assignment follows from its
distribution: if the syllable with a H is initial, italso gets stress; if the syllable with a H is non-initial, the
stress goes to the preceding syllable, forming a disyllabic rising accent (Zsiga & Zec 2013).
Simonović (2018) discusses exceptional preservation of base prosody in Western South Slavic verbs,
showing that WSS verbsallow only two prosodic shapes: stress/H stem-nally
(1a)and stress/H on the
theme vowel (1b), analysed as the contrast between accented and accentless roots. The only verbs
which ever display more contrast are borrowed and denominal verbs (2). Since nouns generally allow
more prosodic contrast than verbs (Smith 2011), Simonović (2018)argues that verb prosody should be
viewed as the regular WSS prosody, whereas all the cases of additional contrast should beanalysed asa
consequence of special Faithfulness, and, at least for the classes discussed by Simonović (2018),asingle
type of special Faithfulness seems to be sucient:
Against the sketched background, variation within WSS is analysed. All three varieties have two
patterns for denominal verbs which both allow for exceptional preservation of the base prosody: -a-ti
and -ov-a-ti (illustrated in 2a; a isatheme vowel in both cases, ti is the innitive
ending). Tellingly, each
variety now hasastabilised borrowing pattern in which one of the two suxes
is used for English verbs
(illustrated in 2b). The necessity ofa denominal verbalisation analysis is relatively limited for Slovenian
and Croatian, where a large majority of verbs (but not all) become reanalysable as verbalised accented
roots (all the verbs in 3 have a stem-nal
stress/H). For Serbian, however, virtually all borrowed verbs
from the modern contact with English display the intermediate root -ov-, which makes the denominal
verbalisation analysis very attractive. Completing the picture for all three varieties, we turn to older
borrowed verbs, especially those from the contact preceding the one with English, in which alarge class
of international verbs were integrated and in which no prosodic contrast is instantiated (4).
In sum, the deverbal nominalisation analysis seems to beastrong cross-linguistic tendency rather than
an absolute rule and its availability depends both on the phonological makeup of the available
denominal verbalisation patterns and on the amount of prosodic contrast in the source language.
