Valency Potential of Slovak and French Verbs in Contrast
Authors: Chovancová Katarína , Ráčková Lucia , Veselá Dagmar , Zázrivcová Monika 
Published: January 2018

Abstract
The paper presents results of synchronous contrastive study of fifteen most frequent Slovak full verbs and their French equivalents by the method of corpus analysis aimed at observation and comparison of their valency potential in relation to their semantic structure. The inventory of valency structures of Slovak verbs and their French equivalents shows not only differences, but also, to a great extent, identical semantic-syntactic connectivities. The main apport of the study lies in the contrastive research perspective and the interdisciplinary character on the crossroads of grammar, semantics, syntax, cognitive and corpus linguistics. Findings can be of use to linguists, terminologists, lexicographers, authors of textbooks and grammars, translators and interpreters, as well as to French-speaking learners of Slovak and Slovak students of French.
Microsyntactic Annotation of Corpora and its Use in Computational Linguistics Tasks
Authors: Iomdin Leonid 
Published: January 2018

Abstract
Microsyntax is a linguistic discipline dealing with idiomatic elements whose important properties are strongly related to syntax. In a way, these elements may be viewed as transitional entities between the lexicon and the grammar, which explains why they are often underrepresented in both of these resource types: the lexicographer fails to see such elements as full-fledged lexical units, while the grammarian finds them too specific to justify the creation of individual well-developed rules. As a result, such elements are poorly covered by linguistic models used in advanced modern computational linguistic tasks like high-quality machine translation or deep semantic analysis. A possible way to mend the situation and improve the coverage and adequate treatment of microsyntactic units in linguistic resources is to develop corpora with microsyntactic annotation, closely linked to specially designed lexicons. The paper shows how this task is solved in the deeply annotated corpus of Russian, SynTagRus.
On the Development of an Interdisciplinary Annotation and Classification System for Language Varieties – Challenges and Solutions
Authors: Kim Agnes , Breuer Ludwig M. 
Published: January 2018

Abstract
The Special Research Programme (SFB) ‘German in Austria: Variation – Contact – Perception’ is a project financed by the Austrian Science Fund (FWF F60). Its nine project parts are collaboratively conducting research on the variation and change of the German language in Austria. The SFB explores the use and the subjective perception of the German language in Austria as well as its contact with other languages. Methodologically and theoretically, most SFB project parts are situated within variationist linguistics, others in contact linguistics and perceptionist linguistics. This paper gives an insight into the conception of a framework for the annotation and ultimately also classification of language varieties, which is being developed within the SFB. It outlines the requirements of the various project parts and reviews, whether and how standardised language codes (ISO 639) and language tags (following BCP 47) can be utilised for the annotation of language varieties in variationist linguistic projects.

Authors: Kolářová Veronika , Vernerová Anna , Klímová Jana , Kolář Jan 
Published: January 2018

Abstract
In order to optimize corpus searches for valency lexicon production, we analyse the relative frequencies of different combinations of valency complementations of Czech deverbal nouns in the Prague Dependency Treebank, considering differences between productively and non-productively derived nouns and their semantic class. We also classify combinations of forms of participants according to their frequency.
What Does že jo (and že ne) Mean in Spoken Dialogue
Authors: Komrsková Zuzana 
Published: January 2018

Abstract
The goal of this paper is to examine the role of two collocations (že jo and že ne) in spoken dialogue. Both are said to be typical of spontaneous conversation and express a large scale of pragmatic functions, e.g. uncertainty of the speaker or a request for a backchannel. The examination of their positioning within the utterance in relation to the meaning of their close context helped us to identify the functions and to distinguish between cases which are simple co-occurrences of the conjunction že and the particle jo/ne, and those which are instances of the set phrase. The source material comes from the ORAL2013 and DIALOG corpora.
Corpus-Based Semantic Models of the Noun Phrases Containing Words with ‘Person’ Marker
Authors: Langenbakh Margaryta 
Published: January 2018

Abstract
The mechanism underlying constructing of lexically correct sequences of words is an object of attention both in theoretical and applied fields of linguistics. This paper reveals some aspects of modelling the patterns of semantic valence in noun phrases of NN (Noun+Noun) structure, one or both components of which contain the ‘person’ semantic tag. The research is based on the Corpus of Ukrainian and performed with the help of automatic language processing.
CzEngClass – Towards a Lexicon of Verb Synonyms with Valency Linked to Semantic Roles
Authors: Urešová Zdeňka , Fučíková Eva , Hajičová Eva 
Published: January 2018

Abstract
In this paper, we introduce our ongoing project about synonymy in bilingual context. This project aims at exploring semantic ‘equivalence’ of verb senses of generally different verbal lexemes in a bilingual (Czech-English) setting. Specifically, it focuses on their valency behavior within such equivalence groups. We believe that using bilingual context (translation) as an important factor in the delimitation of classes of synonymous lexical units (verbs, in our case) may help to specify the verb senses, also with regard to the (semantic) roles relation to other verb senses and roles of their arguments more precisely than when using monolingual corpora. In our project, we work “bottom-up”, i.e., from an evidence as recorded in our corpora and not “top-down”, from a predefined set of semantic classes.

Ján Horecký‘s Approach to Language and Thinking
Authors: Zumrík Miroslav 
Published: January 2018

Abstract
The paper aims to reflect on theoretical foundations of Horecký’s approach to the relation between language (and more specifically: terms) and thinking (concepts). Reflections are devoted to Horecký’s explicit and implicit beliefs on the nature of terms and concepts and their mutual relation, as well as their relation to reality around. Definitions of both term and concept appear in some of Horecký’s major papers. The paper focuses on models of term-concept relation proposed in those papers. Finally, an attempt is made to find some convergences and divergences in theories of Horecký and the Czech logician Pavel Tichý.

Experimental Investigation of Intensity Modulator/Direct Detection (IM/DD) Optical OFDM System with Fiber Bragg Grating (FBG)
Authors: FALL Papa Alioune , Fall Mangone 
Published: January 2018

AbstractTo improve the performance of optical fiber transmission and to compensate the fiber chromatic dispersion (CD), we propose to use fiber Bragg grating (FBG) in intensity modulator/direct detection IM/DD optical orthogonal frequency division multiplexing (OOFDM) system, and experimentally demonstrate 2.5-Gbit/s QPSK-OFDM transmission over 200 km SMF-28. FBG used before the detection as a chromatic dispersion compensation module, reducing the beating noise between ASE noise and OFDM signal. By using the FBG in IM/DD OOFDM system, our experimental results show that the receiver sensitivity was improved about 2 dB at a bit error rate (BER) of $1 \times {10^{ - 3}}$ for 2.5 Gbit/s QPSK-OFDM signals after 200 km SMF-transmission compared to regular system without FBG.

Published: January 2018

SummaryA number of risk behaviours, such as smoking, overweight, excessive alcohol intake, insufficient physical activity, excessive and frequent intake of salt, reduced fruit and vegetable intake, increased fat intake, which constitute living habits of an individual can influence the occurrence of hypertension and hyperglycaemia. The changing of these lifestyles can reduce the risk of developing prehypertension and prediabetes. The survey was conducted at student’s campuses. The respondents were subjected to the height, weight, blood glucose and blood pressure. Respondents filled in previously created questionnaire that was approved by the Ethics Committee for Biomedical Research Faculty of Pharmacy, University of Belgrade. The percentage of respondents with a glucose value above the reference value was 14.6% (n=19), 2.4% (n=3) had values greater than 7 mmol/L without being diagnosed with diabetes, and accordingly, 2.4% (n=3) had elevated HbA1c values (above 42 mmol/mol or 6.0%). The percentage of respondents with elevated systolic and diastolic blood pressure was 14.9% and 7.4% respectively. Regarding calculated risk scores, they showed parallel increase with increas-ing of BMI (HPS), systolic and diastolic pressure (OHS), and glucose concentration (OPS). When analysing all the factors that could cause the later development of diabetes, which is associated with hypertension as well, it is observed that the student population is very much exposed to those factors. The results of this study cannot be representative for the general population of students, but they can provide recommendations for further research.

SummaryAcute lymphoblastic leukemia is the most common childhood malignancy. Optimal use of anti leukemic drugs has led to less toxicity and adverse reactions, and a higher survival rate. Thiopurine drugs, including 6-mercaptopurine, are mostly used as antileukemic medications in the maintenance phase of treatment for children with acute lymphoblastic leukemia. For those patients, TPMT genotype- tailored 6-mercaptopurine therapy is already implemented in the treatment protocols. We investigated the role of TPMT, ITPA, ABCC4 and ABCB1 genetic variants as predictors of outcome and 6-mercaptopurine induced toxicity during the maintenance phase of treatment in pediatric acute lymphoblastic leukemia. Sixty-eight children with acute lymphoblastic leukemia were enrolled in this study. Patients have been treated according to ALL IC-BFM 2002 or ALL IC-BFM 2009 protocols. Toxicity and adverse events have been monitored via surrogate markers (off-therapy weeks, episodes of leu - ko penia and average 6-mercaptopurine dose) and a prob- abilistic model was employed to predict overall 6-mercaptopurine related toxicity. We confirmed that patients with acute lymphoblastic leukemia that carry inactive TPMT allele(s) require 6- mercaptopurine dose reduction. ITPA and ABCC4 genetic variants failed to show an association with 6-mercapto - purine induced toxicity during the maintenance phase. Carriers of ABCB1 variant allele experienced greater hepatotoxicity. The probabilistic model Neural net which considered all the analysed genetic variants was assessed to be the best prediction model. It was able to discriminate ALL patients with good and poor 6-mercaptopurin tolerance in 71% of cases (AUC=0.71). This study contributes to the design of a panel of pharmacogenetic markers for predicting thiopurineinduced toxicity in pediatric ALL.

Published: January 2018

Abstract

Background:
Adults with type 2 diabetes (T2D) have significantly lower gray matter volume (GMV) compared to healthy peers. Whether GMV differences exist in youth with T2D remains unclear. Thus, we compared global and regional GMV between obese youth with T2D with age, race and sex similar healthy controls.

Methods:
In a cross-sectional study, 20 obese youth with T2D underwent T1-weighted brain magnetic resonance imaging (MRI). Comparisons were made to 20 age, race and sex similar controls. Differences in global and regional GMV between groups were identified using voxel-based morphometry (VBM).

Results:
Youth with T2D had a significantly lower global GMV-to-intracranial volume ratio (0.51±0.02 in T2D vs. 0.53±0.02 in controls, p=0.02, Cohen’s d=0.85). There were 14 regions where GMV was significantly lower in the T2D group, and nine of these were found in either the temporal or occipital lobes. There were six regions with increased GMV in T2D. All regional differences were significant at p<0.05 after adjusting for multiple comparisons.

Conclusions:
Results from this pilot study show obese youth with T2D have significantly lower global GMV and regional GMV differences, when compared to their age, race and sex similar peers. Future work is needed to determine whether these brain findings are a direct result of adolescent-onset T2D.
Evaluation of resistance and the role of some defense responses in wheat cultivars to Fusarium head blight
Authors: Khaledi Nima , Taheri Parissa , Falahati-Rastegar Mahrokh 
Published: January 2018

Abstract
Fusarium graminearum and F. culmorum are the causal agents of Fusarium head blight (FHB) in cereal crops worldwide. Application of resistant cultivars is the most effective and economic method for management of FHB and reducing mycotoxin production in wheat. Understanding the physiological and biochemical mechanisms involved in basal resistance of wheat to FHB disease is limited. In this research, after screening resistance levels of eighteen wheat cultivars planted in Iran, Gaskozhen and Falat were identified as partially resistant and susceptible wheat cultivars against Fusarium spp., respectively. Also, we investigated the role of hydroxyl radical (OH−), nitric oxide (NO), callose deposition, lipid peroxidation and protein content in basal resistance of wheat to the hemi-biotrophic and necrotrophic Fusarium species causing FHB. Nitric oxide as a signaling molecule may be involved in physiological and defensive processes in plants. Our results showed that NO generation increased in seedlings and spikes of wheat cultivars after inoculation with Fusarium species. We observed earlier and stronger callose deposition at early time points after infection by Fusarium spp. isolates than in non-infected plants, which was positively related to the resistance levels in wheat cultivars. Higher levels of OH− and malondialdehyde (MDA) accumulation (as a marker of lipid peroxidation) were observed in the Falat than in the Gaskozhen cultivar, under non-infected and infected conditions. So, estimation of lipid peroxidation could be useful to evaluate cultivars’ susceptibility. These findings can provide novel insights for better recognition of physiological and biochemical markers of FHB resistance, which could be used for rapid screening of resistance levels in wheat cultivars against this destructive fungal disease.
A Methodology for the Estimation of the Wind Generator Economic Efficiency
Authors: Zaleskis G. 
Published: January 2018

Abstract
Integration of renewable energy sources and the improvement of the technological base may not only reduce the consumption of fossil fuel and environmental load, but also ensure the power supply in regions with difficult fuel delivery or power failures. The main goal of the research is to develop the methodology of evaluation of the wind turbine economic efficiency. The research has demonstrated that the electricity produced from renewable sources may be much more expensive than the electricity purchased from the conventional grid.
Numerical Approach of a Water Flow in an Unsaturated Porous Medium by Coupling Between the Navier–Stokes and Darcy–Forchheimer Equations
Authors: Hami K. , Zeroual I. 
Published: January 2018

Abstract
In the present research, simulations have been conducted to determine numerically the dynamic behaviour of the flow of underground water fed by a river. The basic equations governing the problem studied are those of Navier–Stokes equations of conservation of momentum (flows between pores), coupled by the Darcy–Forchheimer equations (flows within these pores). To understand the phenomena involved, we first study the impact of flow rate on the pressure and the filtration velocity in the underground medium, the second part is devoted to the calculation of the elevation effect of the river water on the flow behaviour in the saturated and unsaturated zone of the aquifer.
Comparison of Chromatic Dispersion Compensation Method Efficiency for 10 Gbit/S RZ-OOK and NRZ-OOK Wdm-Pon Transmission Systems
Authors: Alsevska A. , Dilendorfs V. , Spolitis S. , Bobrovs Vj. 
Published: January 2018

Abstract
In the paper, the authors compare efficiency of two physical dispersion compensation methods for single channel and 8-channel WDM fibre-optical transmission systems using return-to-zero (RZ) and non-return-to-zero (NRZ) line codes for operation within optical C-band frequencies by means of computer simulations. As one of the most important destructive effects in fibre optical transmission systems (FOTS) is chromatic dispersion (CD), it is very important to reduce its negative effect on a transmitted signal. Dispersion compensation methods that were implemented in the research were dispersion compensating fibre (DCF) and fibre Bragg grating (FBG). The main goal of the paper was to find out which dispersion compensation method (DCF or FBG) provided the highest performance increase for fibre-optical transmission system and provided the longest transmission distance after dispersion compensation was implemented at different locations in the fibre-optical line while RZ or NRZ line codes were used. In the paper the reference point of signal quality for all measurements, which were obtained at the receiver, was BER<10−12.

Published: January 2018

Abstract
In this study we discuss the pricing of weather derivatives whose underlying weather variable is temperature.
The dynamics of temperature in this study follows a two state regime switching model with a heteroskedastic mean
reverting process as the base regime and a shifted regime defined by Brownian motion with nonzero drift.
We develop mathematical formulas for pricing futures and option contracts on heating degree days (HDDs),
cooling degree days (CDDs) and cumulative average temperature (CAT) indices. The local volatility nature of the model in the
base regime captures very well the dynamics of the underlying process, thus leading to a better pricing processes
for temperature derivatives contracts written on various index variables. We use the Monte Carlo simulation method
for pricing weather derivatives call option contracts.
A new hybrid cuckoo search and firefly optimization
Authors: Elkhechafi Mariam , Hachimi Hanaa , Elkettani Youssfi 
Published: January 2018

AbstractIn this paper, we present a new hybrid algorithm which is a combination of a hybrid Cuckoo search algorithm and Firefly optimization. We focus in this research on a hybrid method combining two heuristic optimization techniques, Cuckoo Search (CS) and Firefly Algorithm (FA) for the global optimization. Denoted as CS-FA. The hybrid CS-FA technique incorporates concepts from CS and FA and creates individuals in a new generation not only by random walk as found in CS but also by mechanisms of FA. To analyze the benefits of hybridization, we have comparatively evaluated the classical Cuckoo Search and Firefly Algorithms versus the proposed hybridized algorithms (CS-FA).
Copper-catalyzed asymmetric dearomative borylation: new pathway to optically active heterocyclic compounds
Authors: Ito Hajime 
Published: January 2018

Abstract
Chiral N-heterocyclic organoboronates represent promising intermediates for the preparation of various bioactive and pharmaceutical compounds. We recently reported the first asymmetric dearomative borylation of indoles by copper-catalyzed borylation. Then we further developed dearomatization/enantioselective borylation sequence. Chiral 3-boryl-tetrahydropyridines and chiral boryl-tetrahydroquinolines via the copper(I)-catalyzed regio-, diastereo- and enantioselective borylation of 1,2-dihydropyridines and 1,2-dihydroquinilines, which were prepared by the partial reduction of the corresponding pyridine or quinoline derivatives. This dearomatization/enantioselective borylation procedures provide a direct access to chiral piperidines and tetrahydroquinolines from readily available pyridines or quinolines in combination with the stereospecific transformation of the stereogenic C–B bond.
