Intelligent methods for musical rhythm retrieval.
PublicationW pracy przedstawiono postać funkcji rankingujacej poszczególnych dźwięków frazy muzycznej. Opracowano metodę tworzenia wszystkich możliwych hierarchicznych struktur rytmicznych, zwanych hipotezami rytmicznymi. Otrzymane hipotezy są następnie porządkowane w kolejności malejącej wartości funkcji rankingującej, aby ustalić, która ze znalezionych hipotez będzie uznana za właściwą strukturę rytmiczną utworu muzycznego. Postać funkcji...

Forming and Ranking Musical Rhythm Hypotheses.
PublicationW pracy przedstawiono podstawowe pojęcia i definicje zwiazne z wyszukiwaniem informacji rytmicznej w utworach muzycznych. W muzykologii przyjmuje się, że atrybuty dźwięku, takie jak długość, częstotliwość oraz amplituda dźwięku determinują wagę rytmiczną dźwięku. W artykule przebadano te właściwości fizyczne dźwięku w kontekście okreslenia wagi rytmicznej, czyli miary określającej tendencję dźwięku do znalezienia się na początku...

Information retrieval with semantic memory model
PublicationPsycholinguistic theories of semantic memory form the basis of understanding of natural language concepts. These theories are used here as an inspiration for implementing a computational model of semantic memory in the form of semantic network. Combining this network with a vector-based object-relation-feature value representation of concepts that includes also weights for confidence and support, allows for recognition of concepts...

Dibutyl phthalate disrupts conserved circadian rhythm in Drosophila and human cells
PublicationPeople are constantly exposed to phthalates, due to their common use in the production of plastics, pharmaceuticals, cosmetics and skin care products. The ability of phthalates to disrupt endocrine signaling, leading to developmental, reproductive and metabolic defects, has been studied, yet how phthalates interfere with these biological functions is still unclear. To uncover DBP interacting molecular pathways, we raised Drosophila...

The potential interaction of environmental pollutants and circadian rhythm regulations that may cause leukemia
PublicationTumor suppressor genes are highly affected during the development of leukemia, including circadian clock genes. Circadian rhythms constitute an evolutionary molecular machinery involving many genes, such as BMAL1, CLOCK, CRY1, CRY2, PER1, PER2, REV-ERBa, and RORA, for tracking time and optimizing daily life during day-night cycles and seasonal changes. For circulating blood cells many of these genes coordinate their proliferation,...
