Hypergraphs provide a natural framework for representing neurophysiological interactions distributed across sets of sensors. A key methodological question is how hyperedges should be defined from frequency-resolved electroencephalography/magnetoencephalography (EEG/MEG) data. We demonstrate a construction strategy in which hyperedges are obtained from canonical coherence (caCOH), an extension of coherence that estimates coupling between multidimensional signal spaces. To ...

This paper examines total factor productivity (TFP) dynamics among Russian enterprises from 2018 to 2024, using translogarithmic production function estimates for 290 industries. To address endogeneity and functional dependence issues, we employ the Ackerberg—Caves—Frazer methodology with a control function approach. Our findings reveal distinct sectoral patterns. In mining, both simple average and value-added-weighted TFP rose ...

adaptations that enhance auditory, visual, motor, and cognitive processes. This study investigates how
extensive musical training shapes functional brain connectivity by comparing professional musicians and
non-musicians. Using EEG phase-locking value (PLV) analysis, we examined neural synchronization across
alpha, beta, and gamma frequency ranges during music ...

environment, there is increasing interest in biophilic attitudes — a system of stable views, beliefs, and
evaluations that reflect a person’s relationship with living nature and shape their psychological well-being and
environmentally responsible behavior. Existing tools for their measurement, such as the ...

While recent meta-analytic evidence suggests that masculinity threat has a small-to-medium average effect, recent preregistered replication work has failed to reproduce some influential masculinity-threat effects in a large representative sample, raising questions about ...

Alongside collectivism–individualism, autonomy–embeddedness, and monumentalism–flexibility, emancipative values (EV) constitute one of the most powerful cultural markers of societal differences in economic development, demographic change, and levels of liberal democracy. However, the evolutionary emancipation theory's validity relies on the assumption that values crystallize in early adolescence and persist across the lifespan—a premise lacking robust empirical scrutiny. Given ...
