Abstract
This study applied the analysis of stable isotope ratios as a minimally-invasive tool to estimate the diet of Cricetus cricetus for the first time. We took hair and food samples of three different populations of C. cricetus and analyzed stable carbon and nitrogen ratios. The stable isotope ratios in hamster hairs differed significantly within and between populations according to different sampling seasons and animal ages. Additionally, the isotopic signatures of potential food samples differed between sampling sites and food categories. The isotopic mixing models illustrated that diet composition varied with season and food availability. During the summer season hamsters living in agricultural areas mainly fed on green and ripe crop. In contrast to this, during the winter season ripe crop was the main food component for hamsters in agricultural areas while hamsters living in urban areas fed almost exclusively on nuts. These are, despite a wide variety of available food sources, most suitable for hoarding in the burrow. We conclude that stable isotope analysis of hamster hairs is an appropriate minimal-invasive method to investigate correlations between available and consumed food sources throughout the overall distribution of this species.
On a generalized concept of order relations on B(H)
Authors: Dolinar Gregor , Marovt Janko 
Published: February 2018

Abstract
Let H be a Hilbert space and B(H) the set of all bounded linear operators on H. In the paper we consider the generalized concept of order relations on B(H) which was proposed by Šemrl and which covers the star partial order, the left-star partial order, the right-star partial order, and the minus partial order. We also connect this concept with the sharp partial order.

Bohdan Wodiczko’s Programming Policies at Warsaw Philharmonic (1955-1958). Toward the Warsaw Autumn.
Authors: Klubiński Michał 
Published: February 2018

Abstract
As the managing and artistic director of Warsaw Philharmonic in 1955-58, Bohdan Wodiczko introduced an innovative programming policy which re-oriented the Philharmonic’s repertoire toward 20th-century classics and focused on the links between new music and that of other historical periods. The aim was to create a vast sonosphere of a “musical inter-age” (S. Kisielewski after M. Wańkowicz) encompassing radically different styles and genres and significantly transforming the axiology of the musical art. Wodiczko’s novel programming, though largely concentrating on the already waning neo-Classicism, laid the foundations for the phenomenon of the Warsaw Autumn and was a harbinger of the political-cultural thaw that would come after October 1956. This paper examines Wodiczko’s programming revolution in its political context, as well as the critical reception of Warsaw Philharmonic concerts, with particular emphasis on the aesthetic disputes arising around those composers whose works provoked the greatest controversies: Igor Stravinsky and Carl Orff.
From Restrictions to Freedom The Perilous Path to the First Warsaw Autumn Festival
Authors: Bylander Cindy 
Published: February 2018

Abstract
The genesis of the Warsaw Autumn Festival was fraught with both potential and real complications. Musical life in Poland at the end of the first postwar decade was in a state of flux, if not turmoil, as ideological disagreements and material complications contributed to an atmosphere of dismay and distrust among musicians and authorities. This paper provides insight into the context in which the Festival’s organizers were operating, particularly the shortcomings of musical life in mid-decade that threatened to derail the Festival before it even began.
How Foreign of a Country is the Past? Colonial Archives, Customary Law and Land Transactions in Ghana
Authors: Perneş Raluca 
Published: February 2018

Abstract
This paper looks at a set of documents produced in the early 1950s in the Gold Coast to establish land boundaries in a region and to contribute to the crystallization of customary law for future reference and use. The material is placed in a longer historical flow and seen as one of the results of transformations in the metropole, in the colony, and in their relationship over the first decades of the century, and as a significant landmark collection that has been used in land transactions ever since. The analysis pleads for treating the archives in an ethnographic and not just in an extractive manner (Stoler, 2002, 2009), suggesting that the making, the form, the authors’ stances and the use of the documents can be useful supplementary tools in making sense of the already heavily edited representations of the past that we have access to. The focus on this particular archival material contributes to the discussions about the pitfalls of basing land management on, as Sally Falk Moore would put it, “customary” law.
Football and Romanian Masculinity. How it is constructed by the Sport Media?
Authors: Péter László 
Published: February 2018

Abstract
The present article is focusing on hegemonic masculinity represented and expressed by the professional footballers. Based on the empirical study using text analysis of leading articles published in central Romanian sport newspapers I draw the ideal-typical picture of the normative model of Romanian hegemonic masculinity in which the domestic coaches play a determinant role. Their personal-individual and collective-professional features like determination, steadiness, honesty, pride, mutual respect, knowledge, tenaciousness, sense of vocation, solidarity, spirit of fighting are the corner points of the constructed Romanian manhood, or hegemonic masculinity during social change. The manliness is traced along the inner characteristic of the coaches but in strong contradiction with the foreign trainers. In this respect I can state that football is connected not only with masculinity but in some respect also with the national characteristics embodied by the Romanian coaches especially those working home.
Design of a rotational iron loss measurement system

Published: February 2018

Abstract
This article is about the design of a measurement system for measuring iron losses in soft magnetic composites under controlled circular flux density patterns. With conventional measurement setups for iron loss determination, material samples are usually magnetized along a single spatial direction. However, in some parts of electrical machines magnetization loci over time substantially divert from the patterns used during conventional alternating loss measurements. Based on previous findings, iron losses strongly depend on the actual two dimensional magnetization locus over time. Therefore, the measurement with alternating magnetization cannot fully reflect the magnetizing conditions and iron losses present during machine operation. Available data especially for soft magnetic composites (SMC) regarding rotational losses is very limited. Hence, in this article a new measurement setup for the investigation of iron losses under controlled circular flux density loci was designed. It turns out, that iron losses show a significant deviation when comparing alternating and rotational losses with regard to the flux density magnitude and frequency.

Abstract
Adventitious roots (ARs) of lotus (Nelumbonucifera Gaertn.) play a critical role in water and nutrient uptake. We found that exogenously applied 10-μM indole-3-acetic acid (IAA) promoted the formation of ARs, while 150-μM IAA significantly inhibited the emergence of ARs. However, little is known about these different responses to various concentrations of IAA at the molecular level. This study, therefore, examined the gene expression profiling in four libraries treated with 10- and 150-μM IAA based on the high-throughout tag sequencing technique. Approximately 2.4×107 clean tags were obtained after the removal of low-quality tags from each library respectively, among which about 10% clean tags were unambiguous tag-mapped genes to the reference genes. We found that some genes involved in auxin metabolism showed a similar tendency for expression in the A/CK and C/CK libraries, while three genes were enhanced their expression only in the A/CK libraries. Two transcription factors including B3 domain-containing protein At2g36080-like and trihelix transcription factor were up-regulated for transcriptional level in the A/C libraries. The expressions of six important genes related to AR formation were significantly different in the A/CK and C/CK libraries. In summary, this study provides a comprehensive understanding of gene expression regulated by IAA involved in AR formation in lotus.
GUCY2D Cone–Rod Dystrophy-6 Is a “Phototransduction Disease” Triggered by Abnormal Calcium Feedback on Retinal Membrane Guanylyl Cyclase 1

Published: February 2018

The Arg838Ser mutation in retinal membrane guanylyl cyclase 1 (RetGC1) has been linked to autosomal dominant cone–rod dystrophy type 6 (CORD6). It is believed that photoreceptor degeneration is caused by the altered sensitivity of RetGC1 to calcium regulation via guanylyl cyclase activating proteins (GCAPs). To determine the mechanism by which this mutation leads to degeneration, we investigated the structure and function of rod photoreceptors in two transgenic mouse lines, 362 and 379, expressing R838S RetGC1. In both lines, rod outer segments became shorter than in their nontransgenic siblings by 3–4 weeks of age, before the eventual photoreceptor degeneration. Despite the shortening of their outer segments, the dark current of transgenic rods was 1.5–2.2-fold higher than in nontransgenic controls. Similarly, the dim flash response amplitude inR838S+rods was larger, time to peak was delayed, and flash sensitivity was increased, all suggesting elevated dark-adapted free cGMP in transgenic rods. In rods expressing R838S RetGC1, dark-current noise increased and the exchange current, detected after a saturating flash, became more pronounced. These results suggest disrupted Ca2+phototransduction feedback and abnormally high free-Ca2+concentration in the outer segments. Notably, photoreceptor degeneration, which typically occurred after 3 months of age in R838S RetGC1 transgenic mice inGCAP1,2+/+orGCAP1,2+/−backgrounds, was prevented inGCAP1,2−/−mice lacking Ca2+feedback to guanylyl cyclase. In summary, the dysregulation of guanylyl cyclase in RetGC1-linked CORD6 is a “phototransduction disease,” which means it is associated with increased free-cGMP and Ca2+levels in photoreceptors.SIGNIFICANCE STATEMENTIn a mouse model expressing human membrane guanylyl cyclase 1 (RetGC1,GUCY2D), a mutation associated with early progressing congenital blindness, cone–rod dystrophy type 6 (CORD6), deregulates calcium-sensitive feedback of phototransduction to the cyclase mediated by guanylyl cyclase activating proteins (GCAPs), which are calcium-sensor proteins. The abnormal calcium sensitivity of the cyclase increases cGMP-gated dark current in the rod outer segments, reshapes rod photoresponses, and triggers photoreceptor death. This work is the first to demonstrate a direct physiological effect ofGUCY2DCORD6-linked mutation on photoreceptor physiologyin vivo. It also identifies the abnormal regulation of the cyclase by calcium-sensor proteins as the main trigger for the photoreceptor death.

AbstractNorway spruce (Picea abies) is by far the most important timber species in Europe, but its outstanding role in future forests is jeopardized by its high sensitivity to drought. We analyzed drought response of Norway spruce at the warmest fringe of its natural range. Based on a 35-year old provenance experiment we tested for genetic variation among and within seed provenances across consecutively occurring strong drought events using dendroclimatic time series. Moreover, we tested for associations between ≈1,700 variable SNPs and traits related to drought response, wood characteristics and climate-growth relationships. We found significant adaptive genetic variation among provenances originating from the species’ Alpine, Central and Southeastern European range. Genetic variation between individuals varied significantly among provenances explaining up to 44% of the phenotypic variation in drought response. Varying phenotypic correlations between drought response and wood traits confirmed differences in selection intensity among seed provenances. Significant associations were found between 29 SNPs and traits related to drought, climate-growth relationships and wood properties which explained between 11 and 43% of trait variation, though 12 of them were due to single individuals having extreme phenotypes of the respective trait. The majority of these SNPs are located within exons of genes and the most important ones are preferentially expressed in cambium and xylem expansion layers. Phenotype-genotype associations were stronger if only provenances with significant quantitative genetic variation in drought response were considered. The present study confirms the high adaptive variation of Norway spruce in Central and Southeastern Europe and demonstrates how quantitative genetic, dendroclimatic and genomic data can be linked to understand the genetic basis of adaptation to climate extremes in trees.

Published: February 2018

Abstract
Mutations within STXBP1 have been associated with a range of neurodevelopmental disorders implicating the pleotropic impact of this gene. Although the frequency of de novo mutations within STXBP1 for selective cohorts with early onset epileptic encephalopathy is more than 1%, there is no evidence for a hotspot within the gene. In this study, we analyzed the genomic context of de novo STXBP1 mutations to examine whether certain motifs indicated a greater risk of mutation. Through a comprehensive context analysis of 136 de novo/rare mutation (SNV/Indels) sites in this gene, strikingly 26.92% of all SNV mutations occurred within 5bp upstream or downstream of a ‘GTA’ motif (P &lt; 0.0005). This implies a genomic context modulated mutagenesis. Moreover, 51.85% (14 out of 27) of the ‘GTA’ mutations are splicing compared to 14.70% (20 out of 136) of all reported mutations within STXBP1. We also noted that 11 of these 14 ‘GTA’ associated mutations are de novo in origin. Our analysis provides strong evidence of DNA motif modulated mutagenesis for STXBP1 de novo splicing mutations.

Authors: Zhou Leilei , Chen Zengqiang , Wang Jiezhi , Zhang Qing 
Published: February 2018

In this paper, we first estimate the boundedness of a new proposed 4-dimensional (4D) hyper-chaotic system with complex dynamical behaviors. For this system, the ultimate bound set Ω1 and globally exponentially attractive set Ω2 are derived based on the optimization method, Lyapunov stability theory and comparison principle. Numerical simulations are presented to show the effectiveness of the method and the boundary regions. Then, to prove the existence of hyper-chaos, the hyper-chaotic dynamics of the 4D nonlinear system is investigated by means of topological horseshoe theory and numerical computation. Based on the algorithm for finding horseshoes in three-dimensional hyper-chaotic maps, we finally find a horseshoe with two-directional expansions in the 4D hyper-chaotic system, which can rigorously prove the existence of the hyper-chaos in theory.
Species composition of Dothideomycetes in the anthropogenically transformed ecosystems of the steppe zone of Ukraine
Authors: V. Korolyova O. 
Published: February 2018

The article considers the species composition of the Dothideomycetes and its structural characteristics in conditions of anthropogenically transformed ecosystems of the steppe zone of Ukraine. The materials of the work were the original mycological collection carried out as part of the mycological survey of this territory during 2008–2016, as well as the materials of the herbarium of the Institute of Botany named after M. Kholodny of the National Academy of Sciences of Ukraine. Herbarium collection and identification of the samples were performed in accordance with the generally accepted methods of cameral processing of xylotrophic, herbotrophic and coprothrophic micromycetes. To establish the taxonomic affiliation of species, the method of light microscopy was applied. As a result of our research, the species diversity of ascolocular fungi (Dothideomycetes) has been established in the anthropogenically transformed ecosystems of the steppe zone of Ukraine, which includes 156 species from 43 genera 19 families 5 orders and groups of taxa of Incertae sedis of the subclasses Dothideomycetidae and Pleosporomycetidae. The characteristic features of the taxonomic structure of the investigated mycobiota are the predominance of representatives of the order of Pleosporales, the families Cucurbitariaceae and Mycosphaerellaceae, the genera Cucurbitaria and Mycosphaerella. In the ecological structure of mycobiota in anthropogenically transformed ecosystems saprotrophic and xylotrophic species dominated. The ascolocular fungi species are form consortium connections with 178 species of vascular plants from 112 genera of 51 families, with the largest number of micromycetes (65 species) noted on plants of the Rosaceae. An analysis of the abundance of species in anthropogenically transformed ecosystems of the investigated area showed that 47% of the species are randomly distributed. Widespread species are Dothidea sorbi (Wahlenb.) Sacc., Cucurbitaria caraganae P. Karst., C. amorphae (Wallr.) Fuckel, Botryosphaeria dothidea (Moug.) Ces. & De Not., Otthia spiraeae (Fuckel) Fuckel. In the anthropogenically transformed ecosystems of the steppe zone of Ukraine, in comparison with natural ecosystems, the proportion of species from the genera Cucurbitaria and Mycosphaerella increases quantitatively, and the proportion of Leptosphaeria and Pleospora species decreases. An increase in the proportion of hemibiotrophic species in the ecological structure can be considered a characteristic feature of anthropogenic influence on mycobiota . Comparative analysis of quantitative and qualitative indicators of the mycobiota structure combined with spatial and temporal changes of these indicators can serve as an instrument for indicating its anthropogenic transformation. It would be promising to conduct further research on changes in the species structure of micromycetes exposed to various types of anthropogenic impact in terrestrial ecosystems of the steppe zone of Ukraine.
Sensitivity and resistance of communities: Evaluation on the example of the influence of edaphic, vegetation and spatial factors on soil macrofauna

Published: February 2018

Environmental stability is a multifaceted concept and includes properties such as asymptotic stability, robustness, persistence, variability, elasticity and resistance. Resistance reflects the ability of a community or population to remain in a substantially unaltered state under external influence. The reverse of resistance is sensitivity. This article suggests a way to assess the sensitivity of animal communities to factors of various character and explain sensitivity and resistance of the macrofauna community near the floodplain of the river Dnieper within the "Dnipro-Orelsky" Nature Reserve to the effects of edaphic and plant factors, as well as spatial variables. It is shown that the regulatory impact of environmental factors is refracted through the properties of ecological systems themselves, namely resistance and sensitivity. If an ecological system does not react to changing environmental factors, such a system is indifferent with respect to these factors. In the case of regulatory influence of factors, there may be resistance, sensitivity and the proportionality of the response of the ecological system. The ratio of the specific role of a factor in the variability of a community to the contribution of the main components of the total variability of the attributive space makes it possible to assess the resistance, sensitivity and proportionality of response the ecological system to the action of that factor. If the ratio is >1, then this indicates sensitivity: level of variability of a community is higher than the relative role of environmental factors in the changing of the attributive space. If <1, this indicates resistance: the level of variability of a community is lower than the relative role of environmental factors in the changing of the attributive space. If the ratio =1 (≈1), changes in the community are proportional to the level of the main components of variation in comparison with other components. Ecological factors (both external environmental and internal due to species interactions and which have a neutral nature) cause different levels of community response to their impact. These differences refracted through different aspects of stability of a community can be described using the categories resistance, sensitivity and proportionality. The proposed procedure for quantification of specified properties of sustainability has established that the floodplain soil macrofauna is endowed with resistance to factors that prevail on the level of its variation. However, macrofauna is highly sensitive to minor factors. The community of the soil inhabitants is sensitive to fine-scale variations, which have a neutral nature.
