Opis:
The study investigates the use of speech signal to recognise speakers’ emotional states. The introduction includes the definition and categorization of emotions, including facial expressions, speech and physiological signals. For the purpose of this work, a proprietary resource of emotionally-marked speech recordings was created. The collected recordings come from the media, including live journalistic broadcasts, which show spontaneous emotional reactions to real-time stimuli. For the purpose of signal speech analysis, a specific script was written in Python. Its algorithm includes the parameterization of speech recordings and determination of features correlated with emotional content in speech. After the parametrization process, data clustering was performed to allows for the grouping of feature vectors for speakers into greater collections which imitate specific emotional states. Using the t-Student test for dependent samples, some descriptors were distinguished, which identified significant differences in the values of features between emotional states. Some potential applications for this research were proposed, as well as other development directions for future studies of the topic.

Opis:
In recent years, a significant growth in the population of the European beaver Castor fiber L., both in Poland and around the world, has been observed. Beavers significantly transform the natural environment around the sites where they occur. Therefore, it is important to accurately recognize the colonization patterns of new territories by the European beaver and to gain knowledge about the longevity of populations in already occupied areas. This applies especially to areas of natural value, including protected areas. Fieldwork carried out in the spring of 2021, provided information on the distribution of the European beaver and number of individuals in the Magura National Park (MNP) in the Beskid Niski, an arboreous mountain range in southern Poland. The collected data were compared with similar mappings conducted in this Park in 1996 and 2010. This allowed us to characterize the change dynamics of the beaver population in the MNP area and to describe the changes in spatial distribution of sites inhabited by beavers. During the period of 1996-2021, the population of the European beaver increased from 23-26 to 64 individuals in the study area, with a maximum of 68 in 2010. Beaver colonization of ever smaller watercourses draining higher-located catchments and a change in the characteristics of beaver-inhabited sites have been observed. The average number of dam structures within one site as well as site length have increased. Furthermore, the dominant dwelling type has changed from burrows and open-water lodges to bank lodges, which combine characteristics of the two former. We estimate that the period when beavers migrated further up along the watercourses in the studied area was in the years 2010-2021.

Opis:
PAX8 gene encodes one of the transcription factors engaged in the regulation of proper development of thyroid gland as well as Müllerian and renal/upper urinary tracts. So far, six alternatively spliced transcripts were reported, however, sequences of only four were deposited in the NCBI database. Here, we evaluate a fragment of a novel variant of PAX8 mRNA formed by an alternative 3' acceptor site located in the second exon. The molecular outcome encompasses extension of the 5' untranslated region of exon two by 97 nucleotides as is evident from mRNA. This new insert may impair binding of mRNA to the ribosome and in consequence significantly decrease expression of the PAX8 protein. Here, we show for the first time that the novel insert in exon two might be associated with congenital thyroid hemiagenesis and influence development of different types of cancer.
