GAC: Gene Associations with Clinical, a web based application
Authors: Zhang Xinyan , Rupji Manali , Kowalski Jeanne 
Published: July 2017

We present GAC, a shiny R based tool for interactive visualization of clinical associations based on high-dimensional data. The tool provides a web-based suite to perform supervised principal component analysis (SuperPC), an approach that uses both high-dimensional data, such as gene expression, combined with clinical data to infer clinical associations. We extended the approach to address binary outcomes, in addition to continuous and time-to-event data in our package, thereby increasing the use and flexibility of SuperPC. Additionally, the tool provides an interactive visualization for summarizing results based on a forest plot for both binary and time-to-event data. In summary, the GAC suite of tools provide a one stop shop for conducting statistical analysis to identify and visualize the association between a clinical outcome of interest and high-dimensional data types, such as genomic data. Our GAC package has been implemented in R and is available via http://shinygispa.winship.emory.edu/GAC/. The developmental repository is available at https://github.com/manalirupji/GAC.
RNA substrate length as an indicator of exosome interactions in vivo
Authors: Delan-Forino Clémentine , Schneider Claudia , Tollervey David 
Published: July 2017

Background: The exosome complex plays key roles in RNA processing and degradation in Eukaryotes and Archaea. Outstanding structural studies identified multiple pathways for RNA substrates into the exosome in vitro, but identifying the pathway followed by individual RNA species in vivo remains challenging. Methods: We attempted to address this question using RNase protection. In vivo RNA-protein crosslinking (CRAC) was applied to the exosome component Rrp44/Dis3, which has both endonuclease and exonuclease activity. During CRAC, the exosome was purified under native conditions and subjected to RNase digestion, prior to protein denaturation and cDNA cloning. The resulting high-throughput sequence reads were stratified by length of the cDNA sequence. This should reflect RNA fragment lengths, and therefore the RNA region that was protected by exosome binding. We anticipated major read lengths of ~30nt and ~10nt, reflecting the “central channel” and “direct access” routes to the Rrp44 exonuclease active site observed in vitro. Results: Unexpectedly, no clear peak was observed at 30nt, whereas a broad peak was seen around 20nt. The expected ~10nt peak was seen, and showed strong elevation in strains lacking exonuclease activity. Unexpectedly, this peak was suppressed by point mutations in the Rrp44 endonuclease active site. This indicates that the short fragments are degraded by the exonuclease activity of Rrp44, but also suggests that at least some may be generated by endonuclease activity. Conclusions: The absence of 30nt protected fragments may reflect obligatory binding of cofactors at the entrance to the exosome central channel in vivo. The presence of ~20nt fragments apparently indicates an access route not yet reported from in vitro studies. Confident mapping of 10nt reads is challenging, but they are clearly derived from a subset of exosome targets. In particular, pre-rRNA species, which are major exosome targets, are strongly disfavored for the generation of short reads.
Do research papers provide enough information on design and material used in ankle foot orthoses for children with cerebral palsy? A systematic review
Authors: Eddison N. , Mulholland M. , Chockalingam N. 
Published: July 2017

Objectives The purpose of this article is to determine how many of the current peer-reviewed studies of ankle foot or-thoses (AFOs) on children with cerebral palsy (CP) have included adequate details of the design and material of the AFO, to enable the study to be reproduced and outcomes clearly understood. Methods A thorough search of studies published in English was conducted in March 2015, with no restriction on dates, within all major databases using relevant phrases. These searches were then supplemented by tracking all key references from the appropriate articles identified. Study selection The inclusion criteria were as follows: (1) population - children with CP; (2) intervention - AFOs; and (3) outcome measure. One reviewer extracted data regarding the characteristics of the included studies, with the extracted data checked for accuracy and completeness by a second reviewer. None of the studies reviewed gave adequate details of the AFOs. Only 3.6% (n = 2) of papers tested the stiffness. Many studies (54.5%) did not describe the material used nor the material thickness (72.7 %). None of them gave any clinical justification for the chosen design of AFO. Conclusions There is a clear paucity of detail regarding the design and material used in AFOs on studies involving children with CP. Such a lack of detail has the potential to affect the validity of the reported outcomes, the ability to reproduce the studies and may misinform clinical practice.

Authors: Hermanson M. , Hägglund G. , Riad J. , Rodby-Bousquet E. 
Published: July 2017

Purpose Children with cerebral palsy (CP) are at increased risk for hip dislocation. This can be prevented in most cases using surveillance programmes that include radiographic examinations. Known risk factors for hip dislocation include young age, high Gross Motor Function Classification System (GMFCS) level and high migration percentage (MP). The head-shaft angle (HSA) has recently been described as an additional risk factor. The study aim was to determine inter- and intra-rater reliability of the HSA in a surveillance programme for children with CP. Methods We included hip radiographs from the CP surveillance programme CPUP in southern Sweden during the first half of 2016. Fifty radiographs were included from children at GMFCS levels II-V, with a mean age of 6.6 (SD 3.2) years. Three raters measured the HSA of one hip (left or right) at baseline and four weeks later; intraclass correlation coefficient (ICC) was used to estimate inter- and intra-rater reliability. Results Inter- and intra-rater reliability were excellent for the HSA, with ICC 0.92 (95% CI 0.87-0.96) and ICC 0.99 (95% CI 0.98-0.99), respectively. Conclusion The HSA showed excellent inter- and intra-rater reliability for children with CP, providing further evidence for use of the HSA as an additional factor for identifying risk for further hip displacement or dislocation.
Genealogy, Culture and Technomyth
Authors: Braybrooke Kat , Jordan Tim 
Published: July 2017

Abstract
Western-derived maker movements and their associated fab labs and hackerspaces are being lauded by some as a global industrial revolution, responsible for groundbreaking digital “entanglements” that transform identities, practices and cultures at an unprecedented rate (Anderson 2014; Hills 2016). Assertions proliferate regarding the societal and entrepreneurial benefits of these “new” innovations, with positive impacts ascribed to everything, from poverty to connectivity. However, contradictory evidence has started to emerge, suggesting that a heterogeneous set of global cultural practices have been homogenized. This paper employs a materialist genealogical framework to deconstruct three dominant narratives about information technologies, which we call “technomyths” in the tradition of McGregor et al. After outlining the maker movement, its assumptions are examined through three lesser-cited examples: One Laptop per Child in Peru, jugaad in India and shanzhai copyleft in China. We then explore two preceding technomyths: Open Source and Web 2.0. In conclusion, we identify three key aspects as constitutive to all three technomyths: technological determinism of information technologies, neoliberal capitalism and its “ideal future” subjectivities and the absence and/or invisibility of the non-Western.
Contamination of pine and birch wood dust with microscopic fungi and determination of its sterol contents
Authors: Stuper-Szablewska Kinga , Rogoziński Tomasz , Perkowski Juliusz 
Published: July 2017

Abstract
Wood compounds, especially sterols, are connected with the level of contamination with microscopic fungi. Within this study, tests were conducted on wood dust samples collected at various work stations in a pine and birch timber conversion plant. Their contamination with mycobiota was measured as the concentration of ergosterol (ERG) by ultra performance liquid chromatography (UPLC). Another aim of this study was to assess the effect of contamination with microscopic fungi on the sterol contents in wood dusts. Analyses were conducted on five sterols: desmosterol, cholesterol, lanosterol, stigmasterol, and β-sitosterol using UPLC and their presence was confirmed using gas chromatography/mass spectrometry (GC/MS). The results of chemical analyses showed the greatest contamination with mycobiota in birch wood dust. We also observed varied contents of individual sterols depending on the wood dust type. Their highest concentration was detected in birch dust. The discriminant analysis covering all tested compounds as predictors showed complete separation of all tested wood dust types. The greatest discriminatory power was found for stigmasterol, desmosterol, and ergosterol.
A new, simplified model for the estimation of polyphenol oxidation potentials based on the number of OH groups
Authors: Novak Jovanović Ivana , Miličević Ante 
Published: July 2017

AbstractWe present a new and simpler regression model for the estimation of the first oxidation potentials (Ep1) of flavonoids based on the number of phenolic, alcoholic, and carboxylic OH groups. In the regression we included the Ep1of 12 polyphenols (mostly flavonols and catechins) that were measured in our laboratory at pH 3. The model yielded r=0.986 and SE=0.040. Later successive inclusions of previously reported Epvalues into the regression model, 7 at pH 3, the model (N=19) yielded r=0.980, SE=0.046 and 19 at pH 7 the model (N=38), yielded r=0.985, SE=0.044.
Cumulative Industrial Noise Impact on the Environment
Authors: Wszołek Tadeusz 
Published: July 2017

Abstract
The paper presents basic legal conditions, applicable to the calculation of cumulative noise levels in the environment with indication mainly on lack of detailed regulations both in formal and methodological approach for evaluating those levels. The paper is focused on methodological approach with the emphasison analysis of existing case studies in the industry. The main subject of the analysis is the cumulation of industrial noise sources: newly designed and existing ones, together with a proposal of accumulate other types of the noise. Evaluation of cumulative noise levels for new (designed) objects is realised by computational methods, and for existing objects, by measurements or by combination of measurement and computational methods. It is assumed that the cumulative level is an energetic sum of the rating levels for all installations and it will not exceed the limit value in a given place. For the cumulation of different noise sources, the weighting for criterion values of these sources will be applied in aggregation.

Published: July 2017

Abstract
This paper presents the Automatic Genre Classification of Indian Tamil Music and Western Music using Timbral and Fractional Fourier Transform (FrFT) based Mel Frequency Cepstral Coefficient (MFCC) features. The classifier model for the proposed system has been built using K-NN (K-Nearest Neighbours) and Support Vector Machine (SVM). In this work, the performance of various features extracted from music excerpts has been analysed, to identify the appropriate feature descriptors for the two major genres of Indian Tamil music, namely Classical music (Carnatic based devotional hymn compositions) & Folk music and for western genres of Rock and Classical music from the GTZAN dataset. The results for Tamil music have shown that the feature combination of Spectral Roll off, Spectral Flux, Spectral Skewness and Spectral Kurtosis, combined with Fractional MFCC features, outperforms all other feature combinations, to yield a higher classification accuracy of 96.05%, as compared to the accuracy of 84.21% with conventional MFCC. It has also been observed that the FrFT based MFCC effieciently classifies the two western genres of Rock and Classical music from the GTZAN dataset with a higher classification accuracy of 96.25% as compared to the classification accuracy of 80% with MFCC.
Music Performers Classification by Using Multifractal Features: A Case Study
Authors: Reljin Natasa , Pokrajac David 
Published: July 2017

Abstract
In this paper, we investigated the possibility to classify different performers playing the same melodies at the same manner being subjectively quite similar and very difficult to distinguish even for musically skilled persons. For resolving this problem we propose the use of multifractal (MF) analysis, which is proven as an efficient method for describing and quantifying complex natural structures, phenomena or signals. We found experimentally that parameters associated to some characteristic points within the MF spectrum can be used as music descriptors, thus permitting accurate discrimination of music performers. Our approach is tested on the dataset containing the same songs performed by music group ABBA and by actors in the movie Mamma Mia. As a classifier we used the support vector machines and the classification performance was evaluated by using the four-fold cross-validation. The results of proposed method were compared with those obtained using mel-frequency cepstral coefficients (MFCCs) as descriptors. For the considered two-class problem, the overall accuracy and F-measure higher than 98% are obtained with the MF descriptors, which was considerably better than by using the MFCC descriptors when the best results were less than 77%.
Impulsive Sound Detection Directly in Sigma-Delta Domain
Authors: Miranda Igor D. dos S. , Lima Antonio C. de C. 
Published: July 2017

Abstract
Recent implementations of Sigma-Delta (ΣΔ) converters have achieved low cost, low power consumption, and high integration while maintaining resolution as high as in Nyquist-rate converters. However, its usage implies demodulating the source signal delivered from ΣΔ modulation to Pulse-Code Modulation (PCM) on a pre-processing stage. This work proposes an algorithm based on Discrete Cosine Transform for impulsive signal detection to be applied directly on a modulated ΣΔ bitstream, targeting to reduce computational cost in acoustic event detection applications such as gunshot recognition systems. From pre-recorded impulsive sounds in ΣΔ format, it has been shown that the new method presents a similar error rate in comparison with traditional energy-based approaches in PCM, meanwhile, it reduces significantly the number of operations per unit time.

Abstract
In the paper, there are presented a general description of the constructed measuring system 8AE-PD, the results of calibration of this system by the Hsu-Nielsen method as well as the testing of the measuring system during recording signals generated by Hsu-Nielsen sources in a steel plate and a modeled partial discharge (PD) source. There is also presented the methodology of investigations by the calibrated acoustic emission method. The results of analyses of PD signals coming from the modeled sources are given. In particular, there are described the properties of acoustic emission (AE) signals generated by the PDs as well as the dependencies of the peak-to-peak voltage Umm, the RMS voltage Urms and the descriptors of acronyms ADP and ADC on the apparent charge Q introduced by the modeled PD source. There are determined the limit values of the apparent charge Q introduced by the modeled PD source for which the recorded signal is identified as originating from the PDS.

A Posteriori Modelling-Discretization Error Estimate for Elliptic Problems withL∞-Coefficients
Authors: Weymuth Monika , Sauter Stefan , Repin Sergey 
Published: July 2017

AbstractWe consider elliptic problems with complicated, discontinuous diffusion tensorA0{A_{0}}. One of the standard approaches to numerically treat such problems is to simplify the coefficient by some approximation, sayAε{A_{\varepsilon}}, and to use standard finite elements. In [19] a combined modelling-discretization strategy has been proposed which estimates the discretization and modelling errors by a posteriori estimates of functional type. This strategy allows to balance these two errors in a problem adapted way. However, the estimate of the modelling error was derived under the assumption that the differenceA0-Aε{A_{0}-A_{\varepsilon}}becomes small with respect to theL∞{L^{\infty}}-norm. This implies in particular that interfaces/discontinuities separating the smooth parts ofA0{A_{0}}have to be matched exactly by the coefficientAε{A_{\varepsilon}}. Therefore the efficient application of that theory to problems with complicated or curved interfaces is limited. In this paper, we will present a refined theory, where the differenceA0-Aε{A_{0}-A_{\varepsilon}}is measured in theLq{L^{q}}-norm for some appropriateq∈]2,∞[{q\in{]2,\infty[}}and, hence, the geometric resolution condition is significantly relaxed.

Published: July 2017

Abstract
With the current economic and political instability in Ukraine, children's health is most certainly the best indicator of socioeconomic development within the country and its different regions. This article analyses the socio-economic and environmental determinants of a child’s health in a big city (using the example of Lviv, a city in Ukraine). The demographic indicators of the child population of the city of Lviv and the reasons for mortality were traced; the structure of children’s diseases was analyzed; the factors affecting children’s health potential (such as local budget expenditures on health care, the level of average nominal wages, the ecological situation in the region) were studied. Published and non-published statistical data from the Main Statistical Department of Lviv Region, Lviv City Council were used. Specific consumer behavior among randomly selected Lviv households with children aged between 0-14 years was studied by using a special survey. Research results show the links between socio-economic and ecological factors (local budget expenditures on health care, the level of average nominal wages, the ecological indices in the region), and child mortality. The limited capacity of parents to satisfy the basic needs of households and complete lack, or limitation, of time that parents spend with their children undoubtedly influences the potential of children’s health in a destructive way.
Changes to the structure of the hydrographic network within the Silesia-Cracow area of zinc and lead exploitation
Authors: Pradela Alicja , Zygmuniak Andrzej 
Published: July 2017

Abstract
The traditions related to mining activities in the Silesia-Cracow area go back to the 11th century when lead, silver, and iron ores were exploited from open pit mines. For centuries, the growth in ore exploitation was an incentive for the development of other industries (hard coal mining, steelmaking). This, in consequence, resulted in progressive urbanization. The areas analyzed are of highly transformed character, mainly because of mining activities. These changes are especially seen in relation to the aquatic environment since this component is exposed to heavy modifications due to the mining processes. Hence the study was carried out in order to determine the quantitative changes in the surface hydrographic network. It was found, that of the 62 main watercourses (existing during the whole analyzed period) 25 changed only slightly in terms of their length, 20 shortened by a few hundred meters and 17 lengthened. In the case of the aggregated length of the tributaries, the value increased for the 41 main watercourses, for 10 of them it was constant and was reduced slightly for a further 11. The areas where the length of the watercourses increased and the drainage density grew were found to be as well those where the total area of wetlands decreased. The element of the hydrographic network which was affected by the most changes was the water bodies. During the analyzed period of over 200 years, their number increased from 154 to 1413.
