The present article studies the properties of the phrase Como si no hubiera (un) mañana (‘As if there were no tomorrow’), which more frequently occurs in European Spanish than in other diatopic varieties of that language. As it is shown in the article, the phrase modifies verbs and verbal predicates, being able to perform intensifying quantification.

In the frame of the grammatical description “from meaning to form” the author promotes the thesis that arguments implied by verbal predicates stand in the syntactic position primarily designed for noun phrases.

The author, following the concept of E. Benveniste, considers complex words as a product not only of word-formation derivation, but also of syntactic trans-formation (condensation) of phrases. The object of the transformation is phrases as composite syntactic and semantic constructions, but the derivation itself, i.e. the formation of complex words is carried out in the language according to the same rules as the derivation of simple (not complex) words, and with the same formal techniques as word formation in general, i.e. by affixation and transformation of components of complex words (truncation, interfixation, accent shifts, etc.). At the same time, the syntactic and semantic relations between components that are characteristic of generating phrases retain their meaning in the structure of derived complex words, no matter what models of derivation (semantic and word-forming) they may relate to. Complex words of the same type in their word-formation structure can have completely different semantics, depending on the syntactic and semantic relations that link the components of the original phrases.

The article offers a typology of complex words in the Russian language in terms of their "internal" syntactic and semantic structure. In composites derived from predicative phrases, there are subject, object, locative, temporal, and other semantic models of relations between a predicate and a dependent word. Composites with a supporting noun can be derived both from phrases with a com-positional connection, and from phrases with a subordinate connection (with relations of functional, comparative, and attributive dependence in a broad sense). Similarly, composites with a reference adjective, numeral, and counting words are analyzed. The article contains a criticism of some provisions of the academic "Russian grammar" (1980).

In the paper, various approaches to automatic music audio summarization are discussed. The project described in detail, is the realization of a method for extracting a music thumbnail - a fragment of continuous music of a given duration time that is most similar to the entire music piece. The results of subjective assessment of the thumbnail choice are presented, where four parameters have been taken into account: clarity (representation of the essence of the piece of music), conciseness (the motifs are not repeated in the summary), coherence of music structure, and overall quality of summary usefulness.

The article is devoted to research into the systematization of the structural and semantic types of partially phraseologized sentences. Partially phraseologized sentences have been ascertained to have their functional and communicative purpose in language and speech. The formal and semantic principles of the typology of partially phraseologized sentences have been determined. Structural typologies of partially phraseologized sentences are based on quantitative and morphological criteria. Analyzed have been the structural types of partly phraseologized sentences. Partially phraseologized sentences are formed by two‑, three‑, four‑, and five‑part phrase‑complexes. The semantic types of partially phraseologized sentences are based on the type of syntactic relations between their two parts, depending on which we can single out: 1) sentences with temporal relations; 2) sentences with relations of generalized condition; 3) sentences with explanatory relations; 4) sentences with applicative relations.
