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. Physics behind the Conformational Transitions in Biopolymers. Demystification of DNA melting and Protein FoldingArtem Badasyan, invited lecture at foreign university Abstract: Biophysics is the area of research, devoted to the studies of physical problems related to living systems. Animal cell is the smallest unit of an organism and mainly contains water solutions of structurally inhomogeneous polymers of biological origin: polypeptides (proteins) and polynucleotides (DNA, RNA). Statistical physics of macromolecules allows to describe the conformations of both synthetic and bio-polymers and constitutes the basis of Biophysics. During the talk I will report on the biophysical problems I have solved with numerical simulations (Langevin-based Molecular Dynamics of Go-like protein folding model and Monte Carlo with Wang-Landau sampling) and analytical studies of spin models (formula evaluation by hand, enforced with computer algebra systems). The direct connections with the theory of phase transitions, algebra of non-commutative operators and decorated spin models will be elucidated.

Keywords: We live in a golden age for astro-particle physics, with a significant number of experiments actively monitoring high-energy Universe. Many of these probes provide excellent tests of particle physics models of dark matter particles. In particular, experiments such as Fermi -LAT, AMS-02, Ice Cube, ... are significantly cutting into the parameter space of one of the most popular candidates, the WIMPs. In this talk I will describe some of the strategies and methods used to search for dark matter with astrophysical data. Special attention will be given to the latest indications of an unaccounted gamma-ray excess at few GeV in the Fermi-LAT data in the region around the Galactic Centre, which steered lots of attention as it was shown to be consistent with putative signals of WIMP dark matter particles and complementary constraints provided by other experiments. Finally I will discuss projections of the expected sensitivities with upcoming experiments and continued data taking with current ones.

7. On the interpretation of scalar implicatures infirst andsecond languageGreta Mazzaggio, Daniele Panizza, Luca Surian, 2021, original scientific article Abstract: We investigated the effect of presenting items in a foreign language (L2) on scalar- implicatures computation. To ensure that L2 processing was more effortful than the pro- cessing of the native language (L1), participants were late learners of L2 immersed in an L1 environment and they were presented with oral stimuli under time constraints. If scalar- implicatures computation requires cognitive effort one should !nd that people are more likely to compute scalar implicatures in L1 than in L2. In two experiments, participants were asked to perform a Sentence Evaluation Task either Italian, their native language, or in a foreign language (English or Spanish). The task included underinformative statements such as “Some dogs are animals” that, if interpreted in a pragmatic way (i.e., “Some but not all dogs are animals”) should be rejected as false. In both experiments, we found more rejections in the native language condition than in the foreign language conditions. These results provide support for models that maintain that scalar-implicature computation is effortful.

8. SUSTAINABLE ASSESSMENT OF ENERGY RECOVERY FROM ORGANIC WASTE WITH A FOCUS ON WASTE FROM OLIVE OIL PRODUCTIONIrena Subotić, 2022, master's thesis Abstract: The need for a Circular Economy became more than obvious, and in line with that, technologies for utilization of renewables and waste-to-energy transformation have become of utmost importance in climate change mitigation. This master thesis deals with treating the waste after olive oil extraction and using anaerobic digestion to turn the waste into a biogas that later can be used for electricity and heat production. Since there are two options for location, it was necessary to use decision support models to remove subjectivity and bias from the decision-making process. After the decision was made, there was an economic analysis of a biogas plant project that later can be used for establishing a new company in Italy. According to the economic indicators, with a profit of 5.243.000 EUR after ten years and an investment return of less than five years, a biogas plant in Italy is a profitable investment. From the aspect of Circular Economy, the biogas plant successfully fits the concept. It has added value to the local community by turning one process by-product into primary material for another process, creating jobs and generating revenue for the municipal budget while preserving natural resources.
