1. Extension of the measurement of the proton-air cross section with the Pierre Auger ObservatoryMarko Zavrtanik, Danilo Zavrtanik, Lili Yang, Serguei Vorobiov, Darko Veberič, Marta Trini, Samo Stanič, Ahmed Saleh, Gašper Kukec Mezek, Andrej Filipčič, Ralf Ulrich, 2015, published scientific conference contribution Abstract: With hybrid data of the Pierre Auger Observatory it is possible
to measure the cross section of proton-air collisions at
energies far beyond the reach of the LHC. Since the first
measurement by the Pierre Auger Collaboration the event
statistics has increased significantly. The proton-air
cross section is now estimated in the two energy intervals in
lg(E/eV) from 17.8 to 18 and from 18 to 18.5. These energies
are chosen so that they maximise the available event statistics
and at the same time lie in the region most compatible with a
significant primary proton fraction. Of these data, only the
20% of most proton-like events are considered for the
measurement. Furthermore, with a new generation of hadronic
interaction models which have been tuned to LHC data, the
model-dependent uncertainties of the measurement are re-visited.

2. Status and Prospects of the Auger Engineering Radio ArrayMarko Zavrtanik, Danilo Zavrtanik, Lili Yang, Serguei Vorobiov, Darko Veberič, Marta Trini, Samo Stanič, Ahmed Saleh, Gašper Kukec Mezek, Andrej Filipčič, Johannes Schulz, 2015, published scientific conference contribution Abstract: The Auger Engineering Radio Array (AERA) is an extension of the
Pierre Auger Observatory. It is used to detect radio emission
from extensive air showers in the 30 - 80 MHz frequency band.
A focus of interest is the dependence of the radio emission on
shower parameters such as the energy and the atmospheric depth
of the shower maximum. After three phases of deployment, AERA
now consists of 153 autonomous radio stations with different
spacings, covering an area of about 17 km2. The size, station
spacings, and geographic location at the same site or near other
Auger extensions, are all targeted at cosmic ray energies above
10[sup]17 eV. The array allows us to explore different
technical schemes to measure the radio emission as well as to
cross calibrate our measurements with the established baseline
detectors of the Auger Observatory. We present the most recent
technological developments and selected experimental results
obtained with AERA.

9. Quantifiers and pragmatic enrichmentPenka Stateva, unpublished invited conference lecture Abstract: One of the most studied scales in the literature on scalar implicatures is the quantifier scale. While the truth of 'some' is entailed by the truth of 'all', 'some' is felicitous only when 'all' is false. This opens the possibility that 'some' would be felicitous if, e.g., almost all of the objects in the restriction of the quantifier have the property ascribed by the nuclear scope. This prediction from the standard theory of quantifier interpretation clashes with native speakers’ intuitions. In Experiment 1 we report a questionnaire study on the perception of quantifier meanings in English, French, Slovenian and German which points to a cross-linguistic variation with respect to the perception of numerical bounds of the existential quantifier. In Experiment 2, using a picture choice task, we further examine whether the numerical bound differences correlate with differences in pragmatic interpretations of the quantifier 'some' in English and 'quelques' in French and interpret the results as supporting our hypothesis that 'some' and its cross-linguistic counterparts are subjected to different processes of pragmatic enrichment.

10. Do children use language structure to discover the recursive rules of counting?Petra Mišmaš, Priyanka Biswas, Rok Žaucer, Franc Marušič, Jessica Sullivan, Rose M. Schneider, Vesna Plesničar, David Barner, 2020, original scientific article Abstract: We test the hypothesis that children acquire knowledge of the successor function — a foundational principle stating that every natural number n has a successor n + 1 — by learning the productive linguistic rules that govern verbal counting. Previous studies report that speakers of languages with less complex count list morphology have greater counting and mathematical knowledge at earlier ages in comparison to speakers of more complex languages (e.g., Miller & Stigler, 1987). Here, we tested whether differences in count list transparency affected children’s acquisition of the successor function in three languages with relatively transparent count lists (Cantonese, Slovenian, and English) and two languages with relatively opaque count lists (Hindi and Gujarati). We measured 3.5- to 6.5-year-old children’s mastery of their count list’s recursive structure with two tasks assessing productive counting, which we then related to a measure of successor function knowledge. While the more opaque languages were associated with lower counting proficiency and successor function task performance in comparison to the more transparent languages, a unique within-language analytic approach revealed a robust relationship between measures of productive counting and successor knowledge in almost every language. We conclude that learning productive rules of counting is a critical step in acquiring knowledge of recursive successor function across languages, and that the timeline for this learning varies as a function of count list transparency.
