Narodnost Neuvostoliiton musiikkipolitiikassa 1930-luvulla
2018
Artikkeli käsittelee yhden keskeisimmän sosialistista realismia määrittäneen alakäsitteen, narodnostin (suom. ”kansallisuus” tai ”kansanomaisuus, kansanomainen henki, kansallinen omaleimaisuus”), historiaa ja käyttöönottoa Neuvostoliiton musiikkipolitiikassa 1930-luvulla. Tutkimuksellisena lähestymistapana sovelletaan käsitehistorian ja diskurssintutkimuksen periaatteita kiinnittäen huomiota erityisesti poliittisesti merkityksellisten käsitteiden historiallisuuteen. Narodnost oli käsite, jonka avulla perusteltiin taidemusiikin kaanonin ja erityisesti romantiikan aikakauden musiikin sopivuus sosialistiseen yhteiskuntaan. Käsitteen avulla vallankumouksellisuuden ja edistyksellisyyden diskurss…

Measuring the Task Induced Oscillatory Brain Activity Using Tensor Decomposition
2019
The characterization of dynamic electrophysiological brain activity, which form and dissolve in order to support ongoing cognitive function, is one of the most important goals in neuroscience. Here, we introduce a method with tensor decomposition for measuring the task-induced oscillations in the human brain using electroencephalography (EEG). The time frequency representation of source-reconstructed singletrail EEG data constructed a third-order tensor with three factors of time ∗ trails, frequency and source points. We then used a non-negative Canonical Polyadic decomposition (NCPD) to identify the temporal, spectral and spatial changes in electrophysiological brain activity. We validate …
Weighted local second-order statistics for complex spatio-temporal point processes
2019
Spatial, temporal, and spatio-temporal point processes, and in particular Poisson processes, are stochastic processes that are largely used to describe and model the distribution of a wealth of real phenomena. When a model is fitted to a set of random points, observed in a given multidimensional space, diagnostic measures are necessary to assess the goodness-of-fit and to evaluate the ability of that model to describe the random point pattern behaviour. The main problem when dealing with residual analysis for point processes is to find a correct definition of residuals. Diagnostics of goodness-of-fit in the theory of point processes are often considered through the transformation of data in…
Diagnozowanie sprawności mówienia w perspektywie (nie tylko) egzaminu maturalnego
2015
The article discusses the difficulties of diagnosing speaking skills in the situation of matriculation examination, resulting from the specific nature of spoken language varieties and texts implementation in these variants. Factors that should be taken into account when formulating criteria for assessing speech and conversation exams are: complex and holistic structure of spoken speech, transience of audible text, the spontaneity of live speech, the power of nonverbal codes, a significant stigma of a dialog, and the influence of situational context on the course of communicative interaction. The analysis of speaking skills assessment tools prepared for the oral examination in the year 2015…
La inscripción de la ciudadanía en la cuba neocolonial (1902-1919) : Sucinta referencia histórico-jurídica
2021
This historical-legal account brieflycovering 17 years of civil registration activity carried out during the neocolonial period by Municipal Judges and Secretaries, specifically that related to registration of Cuban citizens)becomes considerably relevant to understand and to godeeper into the origins of this complex process, as well asto achieve a re-encounter with the history of those who passed through those times, currently a hidden history in the shadows of Civil Registration offices, but still alive and thus allowing us to find all the beauty that there was in it.
Gallium preference for the occupation of tetrahedral sites in Lu3(Al5-xGax)O12multicomponent garnet scintillators according to solid-state nuclear ma…
2019
Abstract In this study, the distributions of aluminum and gallium atoms over the tetrahedral and octahedral sites in the garnet structure were investigated in mixed Lu3Al5-xGaxO12 crystals by using 27Al and 71Ga magic angle spinning nuclear magnetic resonance (NMR) and single crystal 71Ga NMR. The experimental study was supported by theoretical calculations based on density functional theory (DFT) in order to predict the trends in terms of the substitutions of Al by Ga in the mixed garnets. Both the experimental and theoretical results indicated the non-uniform distribution of Al and Ga over the tetrahedral and octahedral sites in the garnet structure, with a strong preference for Ga occupy…
Terahertz Spin‐to‐Charge Conversion by Interfacial Skew Scattering in Metallic Bilayers
2021
The efficient conversion of spin to charge transport and vice versa is of major relevance for the detection and generation of spin currents in spin‐based electronics. Interfaces of heterostructures are known to have a marked impact on this process. Here, terahertz (THz) emission spectroscopy is used to study ultrafast spin‐to‐charge‐current conversion (S2C) in about 50 prototypical F|N bilayers consisting of a ferromagnetic layer F (e.g., Ni81Fe19, Co, or Fe) and a nonmagnetic layer N with strong (Pt) or weak (Cu and Al) spin‐orbit coupling. Varying the structure of the F/N interface leads to a drastic change in the amplitude and even inversion of the polarity of the THz charge current. Rem…
Overexpression of SAMDC1 gene in Arabidopsis thaliana increases expression of defense-related genes as well as resistance to Pseudomonas syringae and…
2014
It has been previously described that elevation of endogenous spermine levels in Arabidopsis could be achieved by transgenic overexpression of S-Adenosylmethionine decarboxylase (SAMDC) or Spermine synthase (SPMS). In both cases, spermine accumulation had an impact on the plant transcriptome, with up-regulation of a set of genes enriched in functional categories involved in defense-related processes against both biotic and abiotic stresses. In this work, the response of SAMDC1-overexpressing plants against bacterial and oomycete pathogens has been tested. The expression of several pathogen defense-related genes was induced in these plants as well as in wild type plants exposed to an exogeno…
Exotic Spin-Orbital Physics in Hybrid Oxides
2016
We compare the effective spin-orbital super\-exchange triggered by magnetic $3d$ impurities with $d^3$ and $d^2$ configurations and either no orbital degree of freedom (orbital dilution) or hole replacing a doublon (charge dilution) in a $4d^4$ Mott insulator with $S=1$ spins. Impurities causing orbital dilution act either as spin defects decoupled from the surrounding ions, or generate orbital polarons along $d^3$-$d^4$ hybrid bonds. The exchange on these bonds determines which orbital is occupied by a doublon on the host site. In case of charge dilution by $3d^2$ impurities additional $\propto T_i^+T_j^+$ terms arise which enhance orbital fluctuations. We show that such terms may radicall…
