Extension of the measurement of the proton-air cross section with the Pierre Auger Observatory
Marko 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.

Physics behind the Conformational Transitions in Biopolymers. Demystification of DNA melting and Protein Folding
Artem 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.

On the interpretation of scalar implicatures infirst andsecond language
Greta 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.
