Systemic and non-systemic valency behavior of Czech deverbal adjectives

We present results of an automatic comparison of valency frames of interlinked adjectival and verbal lexical units based on the valency lexicons NomVallex and VALLEx. We distinguish nine derivational types of deverbal adjectives and examine whether they tend to display systemic or non-systemic valency behavior. The non-systemic valency behavior includes changes in the number of valency complementations and, more dominantly, non-systemic forms of actants, especially a prepositional group.

Non-Systemic Valency Behavior of Czech Deverbal Nouns Based on the NomVallex Lexicon

In order to describe non-systemic valency behavior of Czech deverbal nouns, we present results of an automatic comparison of valency frames of interlinked noun and verbal lexical units included in valency lexicons NomVallex and VALLEX. We show that the non-systemic valency behavior of the nouns is mostly manifested by non-systemic forms of their actants, while changes in the number or type of adnominal actants are negligible as for their frequency. Non-systemic forms considerably contribute to a general increase in the number of forms in valency frames of nouns compared to the number of forms in valency frames of their base verbs. The non-systemic forms are more frequent in valency frames of non-productively derived nouns than in valency frames of productively derived ones.

Automatic comparison of human music, speech, and bird song suggests uniqueness of human scales

The uniqueness of human music relative to speech and animal song has been extensively debated, but never directly measured. To address this, we applied an automated scale analysis algorithm to a sample of 86 recordings of human music, human speech, and bird songs from around the world. We found that human music throughout the world uniquely emphasized scales with small-integer ratios, particularly a perfect 5th (3:2 ratio), while human speech and bird song showed no clear evidence of scale-like tuning. We speculate that the uniquely human tendency toward scales with small-integer ratios may have resulted from the evolution of synchronized group performance among humans.

Basic Principles of Myrmecological Lab-on-a-Chip Design & Application in Ethological Monitoring of Forest Ants for Automatic Comparison with Mathematical Models

Basic Principles of Myrmecological Lab-on-a-Chip Design & Application in Ethological Monitoring of Forest Ants for Automatic Comparison with Mathematical ModelsGradov O.V., Notchenko A.V.This paper describes a new modern construction for ethological monitoring in forest ant colonies. The method to be described here involves some low-cost materials and components. Charge coupled devices or new complementary-symmetry metal–oxide–semiconductor sensors with artificial labyrinth tracks have been successfully used in formicariums or ant colonies. We strongly recommend fluorescent markers as indicators of ant tracks on CMOS or CCD sensors, because this detection method is the most suitable for the problem under consideration. The reader is welcome to check that such similar DIY-systems are both simple and handy for use in myrmecological practice. Градов, О. В., and Нотченко, А. В.
