24. Prosody and discourse structure in native and second language : hands on research using PRAATAlessandra Zappoli, 2022, objavljeni povzetek znanstvenega prispevka na konferenci Opis: This course focuses on the interplay between the speech sciences and the cognitive sciences, addressing the processing and acquisition of prosodic contours in Second Language (L2) Learning.
We will introduce the theoretical framework of Autosegmental Metric Theory of Intonation and ToBI annotation, and we will cover the key notions of signal processing and speech analysis with a hands-on-research practical session, adopting the open-source software PRAAT.
Furthermore, we will present studies targeting the cross-linguistic production of prosodic contours, focusing on the production of native speakers and L2 learners.
Finally, we will address the behavioral and neurophysiological cognitive studies on the auditory processing of prosodic contours, targeting native speakers and L2 learners, and targeting the linguistic and paralinguistic function of pitch in speech. It is suggested to have a laptop and headphones, and to download the software PRAAT at one of the following links:

25. Bioacoustic signal analysis through complex network featuresMohanachandran Nair Sindhu Swapna, RAJ VIMAL, Sankararaman S, 2022, izvirni znanstveni članek Opis: The paper proposes a graph-theoretical approach to auscultation, bringing out the potential of graph features in
classifying the bioacoustics signals. The complex network analysis of the bioacoustics signals - vesicular (VE) and
bronchial (BR) breath sound - of 48 healthy persons are carried out for understanding the airflow dynamics
during respiration. The VE and BR are classified by the machine learning techniques extracting the graph features
– the number of edges (E), graph density (D), transitivity (T), degree centrality (Dcg) and eigenvector centrality
(Ecg). The higher value of E, D, and T in BR indicates the temporally correlated airflow through the wider
tracheobronchial tract resulting in sustained high-intense low-frequencies. The frequency spread and high-frequencies in VE, arising due to the less correlated airflow through the narrow segmental bronchi and lobar,
appears as a lower value for E, D, and T. The lower values of Dcg and Ecg justify the inferences from the spectral
and other graph parameters. The study proposes a methodology in remote auscultation that can be employed in
the current scenario of COVID-19.

26. The atypical pattern of irony comprehension in autistic childrenFrancesca Panzeri, Greta Mazzaggio, Beatrice Giustolisi, Silvia Silleresi, Luca Surian, 2022, izvirni znanstveni članek Opis: Nonliteral language understanding has always been recognized as problematic in autistic individuals. We ran a study on 26 autistic children (mean age = 7.3 years) and 2 comparison groups of typically developing children, 1 matched for chronological age, and 1 of younger peers (mean age = 6.11 years) matched for linguistic abilities, aiming at assessing their understanding of ironic criticisms and compliments, and identifying the cognitive and linguistic factors that may underpin this ability. Autistic participants lagged behind the comparison groups in the comprehension of both types of irony, and their performance was related to mindreading and linguistic abilities. Significant correlations were found between first-order Theory of Mind (ToM) and both types of irony, between second-order ToM and ironic compliments, and between linguistic abilities and ironic criticisms. The autistic group displayed an interesting, and previously unattested in the literature, bimodal distribution: the great majority of them (n = 18) displayed a very poor performance in irony understanding, whereas some (n = 6) were at ceiling. We discuss these results in terms of two different profiles of autistic children.

27. The Structure of the Block Code Generated by a BL-AlgebraHashem Bordbar, 2022, izvirni znanstveni članek Opis: Inspired by the concept of BL-algebra as an important part of the ordered algebra, in this paper we investigate the binary block code generated by an arbitrary BL-algebra and study related properties. For this goal, we initiate the study of the BL-function on a nonempty set P based on BL-algebra L, and by using that, l-functions and l-subsets are introduced for the arbitrary element l of a BL-algebra. In addition, by the mean of the l-functions and l-subsets, an equivalence relation on the BL-algebra L is introduced, and using that, the structure of the code generated by an arbitrary BL-algebra is considered. Some related properties (such as the length and the linearity) of the generated code and examples are provided. Moreover, as the main result, we define a new order on the generated code C based on the BL-algebra L, and show that the structures of the BL-algebra with its order and the correspondence generated code with the defined order are the same.

30. Testing the predictions of axisymmetric distribution functions of galactic dark matter with hydrodynamical simulationsMihael Petač, Julien Lavalle, Arturo Núñez-Castiñeyra, Emmanuel Nezri, 2021, izvirni znanstveni članek Opis: Signal predictions for galactic dark matter (DM) searches often rely on assumptions regarding the DM phase-space distribution function (DF) in halos. This applies to both particle (e.g. p-wave suppressed or Sommerfeld-enhanced annihilation, scattering off atoms, etc.) and macroscopic DM candidates (e.g. microlensing of primordial black holes). As experiments and observations improve in precision, better assessing theoretical uncertainties becomes pressing in the prospect of deriving reliable constraints on DM candidates or trustworthy hints for detection. Most reliable predictions of DFs in halos are based on solving the steady-state collisionless Boltzmann equation (e.g. Eddington-like inversions, action-angle methods, etc.) consistently with observational constraints. One can do so starting from maximal symmetries and a minimal set of degrees of freedom, and then increasing complexity. Key issues are then whether adding complexity, which is computationally costy, improves predictions, and if so where to stop. Clues can be obtained by making predictions for zoomed-in hydrodynamical cosmological simulations in which one can access the true (coarse-grained) phase-space information. Here, we test an axisymmetric extension of the Eddington inversion to predict the full DM DF from its density profile and the total gravitational potential of the system. This permits to go beyond spherical symmetry, and is a priori well suited for spiral galaxies. We show that axisymmetry does not necessarily improve over spherical symmetry because the (observationally unconstrained) angular momentum of the DM halo is not generically aligned with the baryonic one. Theoretical errors are similar to those of the Eddington inversion though, at the 10-20% level for velocity-dependent predictions related to particle DM searches in spiral galaxies. We extensively describe the approach and comment on the results.
