Klapać na pyszczysku, czyli o śląskiej leksyce i frazeologii dotyczącej mówienia
2019
The article discusses selected lexical units found in the dialects of Silesia, which refer to the act of speaking. It examines more than 190 tokens and collocations whose common denominator is the meaning of ‘speaking’. Analyzed are units referring to the content of the expression (with the main semantic component ‘to talk nonsense’), as well as those referring to physical aspects of the act of speaking, such as the clarity and accuracy of articulation (‘to speak indistinctly’, ‘to stutter’), the pace of speaking (‘to speak fast’, ‘to speak slowly’), also the tone, pitch, and intensity of the voice (‘to speak softly’, ‘to say shrilly’). An analysis of the collected material shows that these…
Opis frazeologii w słowniku gwarowym Jana Karłowicza a późniejsza praktyka leksykograficzna
2020
The aim of the article is to show how to list and develop phraseology in the oldest Polish dialect dictionary: A Dictionary of Polish Dialects by Jan Karłowicz, and then discuss the placement of phraseology in the macro- and microstructure of later, 20th century selected dialectal dictionaries. Therefore, the article is an overview of the tradition of lexical development and study of phraseology in dialectal dictionaries (on the example of Silesian Dialect Dictionary, Polish Dialects Dictionary by Polish Academy of Sciences, the dictionary of Bernard Sychta, Dictionary of Ostróda, Warmia and Mazury Dialects).
Miejsce frazeologii w słownikach gwarowych
2016
The aim of this article is to research the ways of developing phraseology and its emplacement into the macro- and microstructure in selected dialectal dictionaries (academic and popular). The first part is an overview of the phraseology, as included in introductions to the dictionaries. In the second part, using specific examples, the author discusses how the methodological and editorial assumptions adopted by dictionary authors/editors are followed in practice. The study of introductions and analysis of the lexical material reveal that in the absence of clearly framed methodological assumptions and detailed editorial guidelines on how to present phraseology in dialectal dictionaries, the q…
Functional characterization of the human tRNA methyltransferases TRMT10A and TRMT10B
2020
Abstract The TRM10 family of methyltransferases is responsible for the N1-methylation of purines at position 9 of tRNAs in Archaea and Eukarya. The human genome encodes three TRM10-type enzymes, of which only the mitochondrial TRMT10C was previously characterized in detail, whereas the functional significance of the two presumably nuclear enzymes TRMT10A and TRMT10B remained unexplained. Here we show that TRMT10A is m1G9-specific and methylates a subset of nuclear-encoded tRNAs, whilst TRMT10B is the first m1A9-specific tRNA methyltransferase found in eukaryotes and is responsible for the modification of a single nuclear-encoded tRNA. Furthermore, we show that the lack of G9 methylation cau…
Eukaryotic rRNA Modification by Yeast 5-Methylcytosine-Methyltransferases and Human Proliferation-Associated Antigen p120.
2015
International audience; Modified nucleotide 5-methylcytosine (m(5)C) is frequently present in various eukaryotic RNAs, including tRNAs, rRNAs and in other non-coding RNAs, as well as in mRNAs. RNA: m(5)C-methyltranferases (MTases) Nop2 from S. cerevisiae and human proliferation-associated nucleolar antigen p120 are both members of a protein family called Nop2/NSUN/NOL1. Protein p120 is well-known as a tumor marker which is over-expressed in various cancer tissues. Using a combination of RNA bisulfite sequencing and HPLC-MS/MS analysis, we demonstrated here that p120 displays an RNA:m(5)C-MTase activity, which restores m(5)C formation at position 2870 in domain V of 25S rRNA in a nop2 Delta …
Generalizability and Simplicity as Criteria in Feature Selection: Application to Mood Classification in Music
2011
Classification of musical audio signals according to expressed mood or emotion has evident applications to content-based music retrieval in large databases. Wrapper selection is a dimension reduction method that has been proposed for improving classification performance. However, the technique is prone to lead to overfitting of the training data, which decreases the generalizability of the obtained results. We claim that previous attempts to apply wrapper selection in the field of music information retrieval (MIR) have led to disputable conclusions about the used methods due to inadequate analysis frameworks, indicative of overfitting, and biased results. This paper presents a framework bas…
Acoustic detection and classification of river boats
2011
We present a robust algorithm to detect the arrival of a boat of a certain type when other background noises are present. It is done via the analysis of its acoustic signature against an existing database of recorded and processed acoustic signals. We characterize the signals by the distribution of their energies among blocks of wavelet packet coefficients. To derive the acoustic signature of the boat of interest, we use the Best Discriminant Basis method. The decision is made by combining the answers from the Linear Discriminant Analysis (LDA) classifier and from the Classification and Regression Trees (CART) that is also accompanied with an additional unit, called Aisles, that reduces fal…
Interactive Multiple Criteria Decision Making based on preference driven Evolutionary Multiobjective Optimization with controllable accuracy
2012
Abstract We present an approach to interactive Multiple Criteria Decision Making based on preference driven Evolutionary Multiobjective Optimization with controllable accuracy. The approach relies on formulae for lower and upper bounds on coordinates of the outcome of an arbitrary efficient variant corresponding to preference information expressed by the Decision Maker. In contrast to earlier works on that subject, here lower and upper bounds can be calculated and their accuracy controlled entirely within evolutionary computation framework. This is made possible by exploration of not only the region of feasible variants – a standard within evolutionary optimization, but also the region of i…
LOCAL CONTROL OF SOUND IN STOCHASTIC DOMAINS BASED ON FINITE ELEMENT MODELS
2011
A numerical method for optimizing the local control of sound in a stochastic domain is developed. A three-dimensional enclosed acoustic space, for example, a cabin with acoustic actuators in given locations is modeled using the finite element method in the frequency domain. The optimal local noise control signals minimizing the least square of the pressure field in the silent region are given by the solution of a quadratic optimization problem. The developed method computes a robust local noise control in the presence of randomly varying parameters such as variations in the acoustic space. Numerical examples consider the noise experienced by a vehicle driver with a varying posture. In a mod…
