An inversion method based on random sampling for real-time MEG neuroimaging
Authors: Pascarella Annalisa , Pitolli Francesca 
Published: February 2019

Abstract
The MagnetoEncephaloGraphy (MEG) has gained great interest in neurorehabilitation training due to its high temporal resolution. The challenge is to localize the active regions of the brain in a fast and accurate way. In this paper we use an inversion method based on random spatial sampling to solve the real-time MEG inverse problem. Several numerical tests on synthetic but realistic data show that the method takes just a few hundredths of a second on a laptop to produce an accurate map of the electric activity inside the brain. Moreover, it requires very little memory storage. For these reasons the random sampling method is particularly attractive in real-time MEG applications.
Extension of tumor fingers: A comparison between an individual-cell based model and a measure theoretic approach
Authors: Scianna Marco , Colombi Annachiara 
Published: February 2019

Abstract
The invasive capability is fundamental in determining the malignancy of a solid tumor. In particular, tumor invasion fronts are characterized by different morphologies, which result both from cell-based processes (such as cell elasticity, adhesive properties and motility) and from subcellular molecular dynamics (such as growth factor internalization, ECM protein digestion and MMP secretion). Of particular relevance is the development of tumors with unstable fingered morphologies: they are in fact more aggressive and hard to be treated than smoother ones as, even if their invasive depth is limited, they are difficult to be surgically removed. The phenomenon of malignant fingering has been reproduced with several mathematical approaches. In this respect, we here present a qualitative comparison between the results obtained by an individual cell-based model (an extended version of the cellular Potts model) and by a measure-based theoretic method. In particular, we show that in both cases a fundamental role in finger extension is played by intercellular adhesive forces and taxis-like migration.

Authors: Filipiak Beata Zofia , Dylewski Marek , Cheba Katarzyna 
Published: February 2019

AbstractThe principle of transparency not only is changing but its importance is increasing. International organizations, including the OECD, are seeking to develop harmonized standards of transparency in public administration. This fact is of particular importance in the search for common solutions for the OECD countries in the implementation of transparency standards, but also this organisation has sought adequate methods for measuring implementation of these standards. The main purpose of the study is to analyze the level of spatial homogeneity in the area of application of the standards of “integrity” of the OECD, which are an expression of the principle of transparency in the member states of this organization, on the European continent. In the study vector calculus was used.
The Significance of Openness and Transparency for Accountability in Public Finances
Authors: Szołno-Koguc Jolanta 
Published: February 2019

Abstract
An essential condition for asserting responsibility in public finances is that they are open and transparent. The Public Finance Act mentions ways of applying the principles of openness, and also stipulates the entities obliged to present data and information on public finances. There is, however, no legislation connected directly with transparency. So do the general requirements of classification and of accountancy and reporting principles constitute sufficient premises for accountability and asserting responsibility? An analysis of the reports and documents concerning the Polish public finance sector indicates that the processes of collecting and spending public funds are insufficiently transparent. The information system enables formal verification of discipline of public finances; however, it does not provide a sufficient basis to assess the effectiveness and efficiency, which are of key importance in terms of accountability. The aim of the article is to analyse the requirements and standards in the field of openness and transparency insofar as these concern the responsibility and accountability of public authorities, along with elements of how these are assessed in the Polish public finance system. A normative descriptive method was applied which took into consideration elements of finance theory, as well as an analysis of practical experience in the field of how public sector bodies function in Poland. The research objectives are realised mainly on the basis of a critical review of the literature on the subject, and an analysis of legal acts, reports and other documents of domestic and international institutions. The considerations and analyzes have led to several key applications to develop the principles of openness and transparency in relation to improving the accountability of public finances.
On Atriplex canescens (Chenopodiaceae s. str./Amaranthaceae s. l.) in Tunisia: nomenclatural and morphological notes on its infraspecific variability
Authors: Iamonico Duilio , Mokni Ridha El 
Published: February 2019

Abstract
Populations of Atriplex canescens var. gigantea were found in Lamta, Bouficha-Enfidha (central Tunisia), and Medenine (southern Tunisia). Literature data concerning the presence of this species in Tunisia are contradictory but now our data confirm its occurrence in the country. On the other hand, this variety is reported in the present paper for the first time both in Tunisia and in North Africa in general. Morphological characters and ecological data are presented, as well as notes about patterns of infraspecific variability of A. canescens. Nomenclatural notes on infraspecific names in A. canescens, as well as on the closely related species A. garrettii, are provided. The types of the names A. canescens var. laciniata, A. canescens var. macilenta, A. garrettii, Obione occidentalis var. angustifolia, and Pterochiton occidentale, that in earlier publications were erroneously considered to be holotypes, are in fact lectotypes (for most of taxa) under Art. 9.10 of the ICN. Isolectotypes were found at CAS (A. canescens var. laciniata and A. canescens var. macilenta), GH (A. canescens var. macilenta), and YU (Atriplex nuttallii).

Published: February 2019

Abstract
Cement is a common and widespread building material over the world. Similarly, carbon dioxide emissions have been significantly increased due to cement production. Alternative low-carbon binders rather than cement have been progressively sought in recent years. Fly ash was found as an available option, since it is being largely disposed annually as a waste material. In this research several studies have been reviewed and recent applications of fly ash on concrete specification, including strength and fracture toughness of green concrete have been perused. Furthermore, transport properties of high volume fly ash after exposure to high temperature and influence of curing temperature on strength development of fly ash-recycled concrete aggregate blends have been investigated. The investigated test results showed that the properties of composites incorporating fly ash depend on the age of the concrete. Test results also revealed that transport properties of concrete increased notably after exposure to 400cº and the results achieved on fly ash-recycled concrete aggregate led to the conclusion that 15% FA is the optimum blend for road stabilization applications.
Comparative Analysis of Structure-From-Motion Software’s –An Example of Letychiv (Ukraine) Castle and Convent Buildings
Authors: Lewińska P. , Pargieła K. 
Published: February 2019

Abstract
Letychiv (pl. Latyczów) is a town located in central Ukraine in the Khmelnytskyi Oblast. It has a unique and complicated history. Second World War left it in ruin, destroying buildings, infrastructure and decimating its once large population. Perhaps the most prominent part of the town currently is the building Dominican convent with adjoin Letychiv Assumption Church. This object is surrounded by what is left of the previously impressive Letychiv Castle, founded by Jan Potocki in 1598. Past 30 years have been dedicated by this small Catholic parish towards rebuilding monastery-castle-church complex. Since this is an ongoing project, it was decided to perform a photographic inventory of the current state of the construction and to create a 3D digital model of the castle, facade of the church and monastery, and the altar. This task have proven to be difficult due to complicated structure of the object. Facades and inner parts of the church are almost white with limited number of distinctive elements, painted in pail gold. Elements other than white are almost identical to each other. It leads to various errors in the processing of Structure-from-motion. This article describes how various versions of SfM algorithm work thru mention difficulties, compares results in terms of accuracy, level of detail and overall look. It also describes how SfM can help to document various stages of restoration of important historical objects.
Forests in the Czech Public Discourse
Authors: Stachová Jana 
Published: February 2019

Abstract
Forests are being increasingly studied within the framework of social sciences, especially in relation to environmental problems and global climate change. This article deals with the perception of Czech forests and their management at two basic levels: at the level of sociological analysis of in-depth interviews with experts in the field of forestry and at the level of public opinion research. The main aim of this study was to describe the attitudes of professionals and the general public towards forests and forestry, especially with regard to climate change. Qualitative analysis of interviews with professionals discerned two main categories of opinion: ecological realism and social constructionism. The results of the study show that the Czech public, in agreement with ecological realists, considers it highly important to preserve and support the non-productive environmental functions of forests. The public also prefers close-to-nature forest management practices. Czech Republic is witnessing a fundamental shift in the mindset about forests. Although the public still expects forests to retain their production function, it perceives their environmental functions as increasingly important.
John Murray and James B. Torrance on Covenant Theology
Authors: Moga Dinu 
Published: February 2019

Abstract
Whatever opinion we might have on the covenants of God with man, we cannot escape the fundamental truth that covenant theology is the best way of presenting the Biblical development of God’s revelation in the history of mankind. Therefore, our duty is to learn to think in covenantal terms, because thinking in covenantal terms means to think biblically. When God, in His sovereignty, has chosen to deal with man, He has chosen to do so through two covenants: the covenant of works, made between God and Adam as the representative head of all mankind, and through the covenant of grace, made between God and Christ on behalf of those who were predestined and elected in Christ.

Abstract
Colonisation of gastrointestinal tract by extended spectrum beta lactamase (ESBL)-producing Gram-negative bacteria is a source for infections. The present work is a prospective study in Latvia aimed to determine the role of two surgical profile wards in transmission of ESBL-producing bacteria. Differences between hospital wards were not analysed due to low number of patients. We have also determined a correlation between the duration of hospitalisation and risk of ESBL colonisation. Tests for ESBL-producing bacteria were made twice for 136 patients — upon admission and upon discharge from the hospital. Of them, 21 (15.4%) patients already were ESBL-positive at the time of admission and 115 (84.6%) patients were ESBL-negative. Upon discharge from hospital, 45 (33.1%) patients were ESBL-positive, one patient was ESBL-negative, and 25 (18.4%) of ESBL-positive cases had emerged during hospitalisation. In total, 46 (33.8%) from 136 patients were ESBL-positive and ESBL was positive in 51 bacterial isolates. On discharge from hospital, the newly acquired ESBL-positive bacterial isolates were K. pneumoniae (n = 18), E. coli (n = 7) and P. mirabilis (n = 3). The prevalence of ESBL-positive E. coli from all detected E. coli was 7.0% and from all Klebsiella spp. — 88.9% in gut flora. Analysis of patientassociated wound infections did not show correlation between the ESBL-producing gut microbiota and the bacterial species involved in wound infection.
The bilingualism wars: Is the bilingual advantage out of (executive) control?
Authors: Fernández-López María , Perea Manuel 
Published: February 2019

Abstract
Whether bilingualism has an effect on the executive function of non-verbal representations is probably one of the most controversial issues in cognitive psychology and cognitive neuroscience. As bilinguals have to alternate between two languages that compete for selection in their daily lives, they make use of selection, inhibition, and monitoring (i.e., components of executive function) more often than monolinguals. Thus, it would not be surprising that these highly trained abilities at selecting and monitoring the linguistic processes would also help the processing of non-linguistic representations. Although the “bilingual advantage” in executive control (Bialystok, 1999) has been repeatedly demonstrated, a number of recent studies—in particular since the publication of the Paap and Greenberg (2013) study—have questioned this effect. Both positive and null findings are currently being published from each of the two sides, thus making it difficult to reach consensus in the scientific community. Here, we propose a plausible solution to this debate: a group of independent researches should carry out a carefully planned large-scale study.

Abstract
Melanonychia refers to a brown or black coloration of the nail plate caused by numerous factors. Regarding the arrangement of pigmentation, we can differentiate between total melanonychia, when pigmentation involves the whole nail plate, or transverse or longitudinal melanonychia, when pigmentation involves the nail in a form of transverse or longitudinal band of pigmentation, respectively. Since longitudinal melanonychia can be a sign of numerous benign and malignant lesions, it often poses a diagnostic challenge for a dermatologist. Herein, we report a case of a 13-year-old girl who developed longitudinal melanonychia on multiple nails after receiving a therapy with azithromycin.

Published: February 2019

Abstract
The article deals with the problem of electric power production in terms of environmental impact, in particular the energy efficiency of its production to utilize primary sources. The efficiency of its production directly depends on the composition of primary sources and technologies used. Difference in efficiency by converting various forms of energy into electrical power and their ratio in the use directly affect the resulting efficiency, production of emissions and thus the environmental impact. Electric traction, its production, is burdened less efficient than other types of tractions used in transport, but at the final reconciliation of their consumption in vehicles, this difference decreases or delays because the vehicles themselves work with different conversion efficiency of its traction on mechanical work, vehicle driving.

Glutathione (GSH) is one of the most important thiol-containing antioxidants involved into various biochemical processes in the human body. Glutathione determination in biological fluids (saliva, urine, serum) and pharmaceutical preparations is rather important for clinical practice. Various analytical methods — spectrophotometry, fluorimetry, high-performance liquid chromatography, NMR spectroscopy, capillary electrophoresis and electrochemical methods — are widely used for this purpose. Electrochemical methods are characterized by easy implementation, low cost and possibility of miniaturization. The electrochemical behavior of reduced (GSH) and oxidized (GSSG) glutathione on a gold-carbon-containing electrode (AuCE) was studied using cathodic voltammetry with different methods of removing oxygen from an electrochemical cell: nitrogen sparging and addition of sodium sulfite (4 mol/dm3). It has been shown that traces of H2O2 that remain in the near-electrode layer on the AuCE even after oxygen removal influence the electrochemical properties of GSH at a cathode sweep of the potential from 0 to –1.8 V: GSH is oxidized by H2O2 to GSSG, the most important product of this reaction is O2. An indirect determination of GSH by the current of oxygen reduction in the Na2SO3 medium in the concentration range from 0.5 × 10–8 to 4.2 × 10–8 mol/dm3 with a detection limit of 2.5 × 10–9 mol/dm3 is proposed. The developed voltammetric method is approved for the determination of GSH in certain pharmaceutical preparations.
Optimal coding of blended seismic sources for 2D full waveform inversion in time

Published: February 2019

Full Waveform Inversion (FWI) schemes are gradually becoming more common in the oil and gas industry, as a new tool for studying complex geological zones, based on their reliability for estimating velocity models. FWI is a non-linear inversion method that iteratively estimates subsurface characteristics such as seismic velocity, starting from an initial velocity model and the preconditioned data acquired.
Blended sources have been used in marine seismic acquisitions to reduce acquisition costs, reducing the number of times that the vessel needs to cross the exploration delineation trajectory. When blended or simultaneous without previous de-blending or separation, stage data are used in the reconstruction of the velocity model with the FWI method, and the computational time is reduced. However, blended data implies overlapping single shot-gathers, producing interference that affects the result of seismic approaches, such as FWI or seismic image migration.
In this document, an encoding strategy is developed, which reduces the overlap areas within the blended data to improve the final velocity model with the FWI method.
