Is <i>Limonium cavanillesii</i> Erben (Plumbaginaceae) really an extant species?
1999
A new triploid apomictic species (Limonium perplexum) is described from a single coastal locality of E Spain. The new species has been previously confused with L cavanillesii Erben, which is only known from few herbarium specimens and it is believed to be extinct. Overall morphology, chromosome number, and the pollen/stigma combination suggest that L perplexum belongs to the L. duriusculum complex. Based on morphological grounds it is suggested that L. cavanillesii Erben could have been originated through a crossing between L perplexum and L dufourii .
Diurnal changes in the perception of emotions in music: Does the time of day matter?
2014
According to the Hindustani music tradition, the ability of a song to induce certain emotions depends on the time of day: playing a song at the right time is said to maximise its emotional effect. The present exploratory study investigated this claim by combining findings in chronobiology, mood research and music perception. It has already been established that some aspects of our mood fluctuations follow a cyclical pattern. Besides, it is a known fact that our current mood influences our perception and assessment of emotions. However, these elements have never been linked together in a study examining the effect of mood cyclicity on perceived emotions in music. To test the hypothesis of a…
Hidden and self-excited attractors in radiophysical and biophysical models
2017
One of the central tasks of investigation of dynamical systems is the problem of analysis of the steady (limiting) behavior of the system after the completion of transient processes, i.e., the problem of localization and analysis of attractors (bounded sets of states of the system to which the system tends after transient processes from close initial states). Transition of the system with initial conditions from the vicinity of stationary state to an attractor corresponds to the case of a self-excited attractor. However, there exist attractors of another type: hidden attractors are attractors with the basin of attraction which does not have intersection with a small neighborhoods of any equ…
Extended music education enhances the quality of school life
2013
The claim of whether music education can create social benefits in the school environment was tested in 10 Finnish schools with an extended music curricular class and control classes. The quality of school life (QSL) was assessed by a representative sample (N=735) of pupils at years 3 and 6 (9- and 12-years-olds). The results showed that extended music education enhances the QSL, particularly in areas related to general satisfaction about the school and a sense of achievement and opportunity for students. Differences related to the schools and gender did not account for the results. A follow-up study examined whether the increase in critical QSL variables was related to music. This analysis…
Systematisation of Systems Solving Physics Boundary Value Problems
2020
A general conservation law that defines a class of physical field theories is constructed. First, the notion of a general field is introduced as a formal sum of differential forms on a Minkowski manifold. By the action principle the conservation law is defined for such a general field. By construction, particular field notions of physics, e.g., magnetic flux, electric field strength, stress, strain etc. become instances of the general field. Hence, the differential equations that constitute physical field theories become also instances of the general conservation law. The general field and the general conservation law together correspond to a large class of relativistic hyperbolic physical …
Halo-like structure in 7He nucleus
2020
A study of the neutron structure of the ground state of 7He has been performed by means of registration and analysis of the decay channels of the residual nuclei following absorption of stopped pions. In particular, the reaction 9Be (${\pi }_{}^{-},d$)X have been investigated where X denotes any system with five neutrons and two protons – the constituencies of a 7He nucleus. It was shown that the structure of 7He is determined by correlations of two neutrons in the states 6He (0+), 6He (2+) and one neutron in the shell p3/2. The 4He+3n structure is not manifested in the ground state of 7He. The obtained results are consistent with the known data on considerable mixture of configurations "6H…
Musical affect regulation in adolescents: A conceptual model
2019
Adolescents actively use music for affect regulation. In this chapter, affect is considered as a broad umbrella term containing moods, emotions, motivational impulses, and energy levels. Theoretical and empirical research has recently been unveiling the components involved in affect self-regulation, such as the psychological functions of music listening, affective goals, regulation strategies, and musical mechanisms. The study of these components and of their interactions has resulted in a better understanding of the dynamics between music engagement, wellbeing, and psychological development among adolescents. The purpose of this chapter is to present a conceptual model of musical affect se…
Influence of Musical Expertise on the processing of Musical Features in a Naturalistic Setting
2019
Musical training causes structural and functional changes in the brain due to its sensory-motor demands, but the modulatory effect of musical training on music feature processing in the brain in a continuous music listening paradigm, has not been investigated thus far. In this work, we investigate the differences between musicians and non-musicians in the encoding of musical features encompassing musical timbre, rhythm and tone. 18 musicians and 18 non-musicians were scanned using fMRI while listening to 3 varied stimuli. Acoustic features corresponding to timbre, rhythm and tone were computationally extracted from the stimuli and correlated with brain responses, followed by t-tests on grou…
Toward a better understanding and conceptualization of affect self-regulation through music : A critical, integrative literature review
2016
Research on the affective phenomena involved in music has grown exponentially over the last 20 years. One particular topic is the use of music for affect self-regulation (i.e., the process of creating, changing, or maintaining affective states). Being a recent field of research, knowledge remains scattered and heterogeneous. An integrative literature review was conducted to present the results from recent research and critically analyse its overall conceptual state. A systematic search of online databases focusing on publications from January 1994 to June 2014 was completed. An extensive screening resulted in the selection of 34 publications, which were analysed with regard to their focus,…
