Managing Software Evolution through Semantic History Slicing

Software change histories are results of incremental updates made by developers. As a side-effect of the software development process, version history is a surprisingly useful source of information for understanding, maintaining and reusing software. However, traditional commit-based sequential organization of version histories lacks semantic structure and thus are insufficient for many development tasks that require highlevel, semantic understanding of program functionality, such as locating feature implementations and porting hot fixes. In this work, we propose to use well-organized unit tests as identifiers for corresponding software functionalities. We then present a family of automated techniques which analyze the semantics of historical changes and assist developers in many everyday practical settings. For validation, we evaluate our approaches on a benchmark of developer-annotated version history instances obtained from realworld open source software projects on GitHub.

Conclusion: Bioimpedance is a suggested method to evaluate clinical and therapeutic follow-up in patients with lymphedema.
Phytochemical screening and antimicrobial activities of some green algae from Egypt

Chlorophytes represent the largest group as eukaryotic photosynthetic green organisms. Most microand macro-green algae are potential sources for active compounds. Ulva sp, Enteromorpha sp, and Chlorella sorokiniana were isolated from the Mediterranean Sea, Port Said, Egypt. The phytochemical constituents (alkaloids, saponins, tannins, terpenoids, flavonoids, cardiac glycosides and anthraquinone) and the antimicrobial properties were investigated for all species` extracts. Cells were dried then grounded. The powdered biomass was soaked into different solvents (methanol and acetone). The antimicrobial activities of different fraction were done using the disc diffusion technique. Results indicated the presence of different active compounds, and the antimicrobial property in all species which increase the importance of them. The phytochemical screening of methanolic and acetonic extract revealed the presence of phytoconstituents including anthraquinones, cardiac glycosides, flavonoids, saponins, tannins and terpenoids. The antimicrobial assessment confirmed the effect of C. sorokiniana extracts on the growth of Escherichia coli and Staphylococcus aureus.
Computation and Knowledge Mapping for Data Entities

This paper presents the research and results from developing resources and knowledge based methods for the creation of new context for objects and entities, based on the methodology of knowledge mapping. The results are an architecture allowing advanced knowledge mapping including flexible deployment of computational sequences and an implementation of resources and application components. The knowledge mapping enables to put knowledge objects in new context, which can be used in arbitrary scenarios, e.g., with knowledge mining and decision making. The paper shows the importance of facilities for different implementations and presents a resulting architecture and case studies of two different implementations for a task. The implementation cases are based on a computational case of spatial visualisation. For demonstration, a publicly available central data object was used for data entity analysis. The paper presents practical examples and discusses the high level views of implementations and case study. The main goal of this research is to create a functional architecture based on sustainable long-term multi-disciplinary knowledge resources, which can provide a wide range of flexibility for knowledge mapping and different computational solutions.

EASD-Experimental Algorithmics for Streaming Data

This paper proposes an experimental methodology for on-line machine learning algorithms, i.e., for algorithms that work on data that are available in a sequential order. It is demonstrated how established tools from experimental algorithmics (EA) can be applied in the on-line or streaming data setting. The massive on-line analysis (MOA) framework is used to perform the experiments. Benefits of a well-defined report structure are discussed. The application of methods from the EA community to on-line or streaming data is referred to as experimental algorithmics for streaming data (EADS).
CSSM : CONCEPT AND STRUCTURAL SIMILARITY METHOD-A SOLUTION ON ACCORDANCE OF METADATA IN LEGACY AND MODERN DATABASE

Importance of a software system is due to its inner data and databases and not to its codes. Therefore, with the appearance of new software, converting data of the previous systems to the new ones is significant and plays an important role in organizations. Although this conversion process may have different phases but the first phase is under consideration in this paper. First phase in the process of converting data, which refers to assessing tables and finding equivalent fields in both legacy and modern databases is being called matching metadata. Considering its’ importance, this paper provides an automatic and intelligent method for assessing table and equivalent fields in both databases and for extracting the degree of their accordance. Then, the proposed method will be evaluated on sample databases and the consequent results will be presented.
ACCESSIBILITY OF HEALTH CARE INSTITUTIONS : A CASE STUDY BY GIS

In this study, the accessibility of health care institutions within the boundaries of Istanbul’s Buyukcekmece district was examined with the help of GIS. First of all, health care institutions located within the boundaries of research area were identified, and, later on, these health care institutions were transferred in a GIS environment. Then, road network, within the boundaries of the district, was digitized with the help of “street” base map of Arc Map 10.1 software and Google Earth. This road network was also later in the determination of settlement areas. In addition, the topographical condition of research area was determined with the help of Digital Elevation Model (DEM) with 30 m resolution obtained from the images of ASTER satellite, and it was discovered that the lowest elevation within the boundaries of the district was 0, and the highest altitude was 221 m. First of all, with the help of data obtained and produced, buffer zones were created around health care institutions and it has been concluded that 20.88% of research areas were 1 km away from health care institutions and 56.33% 0f them were 3 km away from those facilities. In the shortest distance analysis, it has been discovered that health care institutions could be reached from the most distant residential areas within a short period of 20 minutes. As a result, it was concluded that both online data that GIS provided and tools that it used were proved to be very efficient in the measurement of accessibility of heath care institutions, and the efficiency of GIS would increase by developing new technologies and methods.

Theoretical framework : From Balkanization to Europeanization : The multi-level process of WB integration

© 2019 The Author. This article is licensed under a Creative Commons Attribution 4.0 License Abstract. This paper is intended to analyze the challenges and consequences of the integration of Western Balkans to the European Union. Specifically, in the first case, challenges of this integration path and in the second case the consequences as a result of eventual stagnation in this path. For more than a century, the Western Balkans region has been seeking its way of European transformation. The region remains in the agenda of European Union expansion, but even after two decades of promises, the integration of Western Balkan countries to EU is not certain. The integration journey is first of all closely connected to building the institutional capacities, adoption of laws, rules, norms and European behavior in the domestic policymaking. Therefore, the challenges are converted into obstacle or inability to the establishment of values, identity, institutional and social aspects in the Western Balkan countries, whereas the consequences are reflected as derivatives of failure to accomplishing the membership of the region to EU. Based on the research conducted on this issue, this study argues that such challenges as lack of rule of law, high levels of corruption and organized crime are derivatives of historical legacy and political elite efforts to capture the state or dominate certain state resources, as well as of the EU approach towards this region. This study is important particularly in this aspect and unequivocally presents the common and separate challenges of the Western Balkans towards integration into the European Union. Along with this realistic presentation, the consequences themselves appear which first of all are not only to the detriment of the Western Balkans.

The Comparison of Ecological Compensation of the Surrounding Farmers in the Upstream Watershed of Miyun Reservoir

Ecological compensation is one of the most important tools for promoting the construction of ecological civilization and the realization of social justice. It has received extensive attention as the inevitable result of interaction between the development of social economy and environment in recent years. The research area is the upstream area of Miyun reservoir, the Heihe basin in Chicheng County, Zhangjiakou City, as the birthplace of tidal river, combining with the field investigation and the related statistical data, selecting the vital interests of the masses’ paddy land conversion program (PLCP)to analysis, investigating the mechanism to strengthen and perfect the current ecological compensation. The study uses questionnaire investigation method and the multiple regression model of statistics, analysis the problems of behavior and selection of micro economic subject farmers in the ecological compensation mechanism of river basin, determines the value of ecological compensation willingness of farmers, and does comparative analysis of the main factors which influence the ecological compensation willingness of the farmers in the upstream of Miyunreservoir watershed. It takes the upstream watershed of Miyun reservoir as an example, uses the contingent valuation method (CVM), calculates the " PLCP " ecological compensation willingness of the farmers in the Miyun Reservoir upstream in 2007 and 2014, the results of the study show that is 3871.725 RMB//hm2 and 3504.398 RMB//hm2 respectively; The analysis of Logistic regression model showed that, the same factors that influence farmers’ ecological compensation willingness at the same time are the area of paddy field accounted for the proportion of the total area of cultivated land in 2007 and 2014, another significant factors are mainly the average annual family income, whether have the non-agricultural income, the distance from the farmer household production area to the water core protected area, whether rice paddies crop production is serious due to change to dry field. This paper takes that it should be dominated by government, increase the intensity of river basin ecological compensation and the establishment of long-term mechanism of ecological compensation. It has reference value to promote and implement the ecological compensation mechanism of China's River basin, especially for improve the ecological compensation mechanism in Miyun Reservoir watershed.
5 A MODELING INVESTIGATION OF NEAR-CLOUD TURBULENCE

Atmospheric turbulence poses a significant risk to the aviation community. Such turbulence has a variety of well known sources, which include thunderstorms, mountain ranges, and jet streams. However, the generation of turbulence by these sources is not particularly well understood. The current study seeks to investigate possible mechanisms which cause turbulence in the clear-air surrounding developing thunderstorms. This study is motivated by a specific turbulence encounter by a commercial jet.
Fine particle characterization in a coastal city in China: composition, sources, and impacts of industrial emissions

Abstract. Aerosol composition and sources have been extensively studied in developed regions in China. However, aerosol chemistry in coastal regions of eastern China with high industrial emissions remains poorly characterized. Here we present a comprehensive characterization of aerosol composition and sources near two large steel plants in a coastal city in Shandong in fall and spring using a PM2.5 time-of-flight aerosol chemical speciation monitor. The average (±1σ) mass concentration of PM2.5 in spring 2019 (54±44 µg m−3) was approximately twice that (26±23 µg m−3) in fall 2018. Aerosol composition was substantially different between the two seasons. While organics accounted for ∼30 % of the total PM2.5 mass in both seasons, sulfate showed a considerable decrease from 28 % in September to 16 % in March, which was associated with a large increase in nitrate contribution from 17 % to 32 %. Positive matrix factorization analysis showed that secondary organic aerosol (SOA) dominated the total OA in both seasons, accounting on average for 92 % and 86 %, respectively, while the contribution of traffic-related hydrocarbon-like OA was comparable (8 %–9 %). During this study, we observed significant impacts of steel plant emissions on aerosol chemistry nearby. The results showed that aerosol particles emitted from the steel plants were overwhelmingly dominated by ammonium sulfate and/or ammonium bisulfate with the peak concentration reaching as high as 224 µg m−3. Further analysis showed similar mass ratios for NOx∕CO (0.014) and NOx∕SO2 (1.24) from the two different steel plants, which were largely different from those during periods in the absence of industrial plumes. Bivariate polar plot analysis also supported the dominant source region of ammonium sulfate, CO, and SO2 from the southwest steel plants. Our results might have significant implications for better quantification of industrial emissions using ammonium sulfate and the ratios of gaseous species as tracers in industrial regions and nearby in the future.
Parametric invariance of the relativistic coordinate pulsar time scales

The accuracy of modern astronomical observations so high that in order to understand what we see and how you can, you must use meaningful relativistic models of the observable processes. Effect of relativity can’t be reduced in this case to small corrections of the Newtonian model. On the contrary, the whole concept of astronomical reference systems and astronomical observations should be revised and adapted to the framework of the theory of relativity. (S.Klioner, 1995)
ull length article en shades of truth : A study of Australian journalists ’ shift to olitical

The use of manipulative overt and covert ‘spin’ tactics by parliamentary media advisers to embellish, obfuscate and evade has been well documented. However, there has been less attention paid to the way journalists adapt to ‘spin’ culture and interpret truth once they become parliamentary media advisers. Based on inductive analysis of in-depth semistructured interviews with twenty-one Australian journalists who made the transition to parliamentary media advising, this paper offers a typology of ten subtle approaches to truth telling adopted by these journalists in their new role as political media advisers. The interview data revealed a range of pragmatic approaches including: ‘triage’, ‘putting the best foot forward’, ‘never tell a lie’, ‘playing a dead bat’, and ‘don’t ask, don’t tell’. Through the comparative insights of journalists who have worked as parliamentary media advisers, the practitioner reflections in this paper complicate the blunt conception of the mendacious ‘spin-doctor’ and point to the malleability of ‘truth’ in both communications roles. © 2016 Elsevier Inc.

Conductive Polymers and their Nanohybrid Transducers for Electrochemical Biosensors Applications : A Brief Review

In the present article, we briefly review the characteristics, synthetic strategies, and notable applications of conducting polymers and their nanohybrids as transducers in electrochemical biosensors. The conducting polymers show unusual electrochemical properties, and they can be directly electrodeposited on the electrode substrate in the form of a thin polymer film which can later be modified with biomolecules. On the other hand, the nanostructured hybrid materials have beneficial advantages such as high surface area and small dimensions. The enlarged surface area enhances the interactions between the electrode materials and analytes, which facilitate adsorption/desorption kinetics for analytes in the materials, which allows a rapid response time and high signal reproducibility. The conducting polymer-based nanohybrids have several synergistic properties between the polymer and the nanomaterials, making them promising candidates for application in sensors as transducers.
Species boundary and extensive hybridization and introgression in Petunia

Studying the role of hybridization in the speciation of plants is one of the most thrilling areas of evolutionary biology. Hybridization in natural populations can act in opposition to divergence, contribute to adaptation through introgression or foster the emergence of new lineages via hybrid speciation. Species of the plant genus Petunia grow in open areas in southern South America. Some natural interspecific hybrid events have been described for the genus, such as between the endemic P. exserta and the widespread P. axillaris. Both species occur in sympatry in Serra do Sudeste (Brazil), where they occur in diverse habitats and exhibit floral divergence, which has been related to the attraction of different primary pollinators. The present study evaluates the maintenance of the species boundaries front of hybridization and introgression. Direct and indirect methods of estimating gene exchange employed genotyping 720 reproductive plants and 611 progenies of both species with eight microsatellite loci. Gene exchange was found to be frequent and bidirectional between the species, indicating that introgression changes their genetic constitution in areas of sympatry. Limits of the studied species are being maintained because of the high level of inbreeding and backcrosses that are habitat-dependent.
