Cognitive Wireless Communications – A paradigm shift in dealing with radio resources as a prerequisite for the wireless network of the future – An overview on the topic of cognitive wireless technologies
Authors: Haustein Thomas , Stanczak Slawomir , Wolisz Adam , Jondral Friedrich , Schotten Hans , Kraemer Rolf , Mück Markus , Mennenga Horst , Bender Paul 
Published: June 2016

AbstractWireless radio communications systems form the basis for mobile network connections in the digital society. A limited amount of radio spectrum and a spatially densified use of wireless communications systems require a resource-efficient use of the spectrum. Mechanisms of cognitive radio may hold the key to a more efficient use of the available spectrum under consideration of quality of service requirements. These mechanisms take advantage of location-specific knowledge of the wireless channel occupation in the dimensions of frequency, time, location and direction in space and therefore enable co-existent and reliable wireless communication. The authors give an introduction to the status of cognitive wireless communication technology, which represents the starting point of a series of research projects promoted by BMBF during 2012–2014.
The Status of Urban and Suburban Sprawl in Egypt and Iran
Authors: Gouda Amr Ah. , Hosseini Maryamsadat , Masoumi Houshmand E. 
Published: June 2016

Abstract
The circumstances of urban sprawl in the Middle Eastern cities have been basically examined; now we are aware of the existence of a crawling sprawl in the growth pattern of the region’s cities. Nevertheless, the extent and the causes of this phenomenon have not yet been clearly explained. Thus, two questions are still unanswered: (1) to what extent are the Middle Eastern cities sprawled?, (2) what are the main drivers of sprawl in the Middle East? This paper brings together several evidences from international and the national languages to provide explanation to the above. The findings show that urban and suburban sprawl is an inclusive pattern seen in a wide variety of city sizes, planning concepts, times, etc. Sprawl is not limited to large metropolitan areas; mid-sized and small cities of the region are also sprawling. Furthermore, administrative and planning reasons are the strongest causes of urban sprawl in the region.
Location of super and hypermarkets in the city of Ústí nad Labem
Authors: Olšová Petra , Jánská Michaela 
Published: June 2016

Abstract
Retail stores are a common part of our everyday life. We focus on the site selection of supermarkets and hypermarkets in Ústí nad Labem and analyze the role of selected factors that drive the site selection of these super/hypermarkets. The role of the factors is verified by a correlation analysis. In the city of Ústí nad Labem, retail units of the supermarket or hypermarket type are unevenly distributed and are concentrated in the more central areas of the city. The location of stores has no power association with monitored factors. The result is certainly strongly influenced by the lack in availability of relevant data.
Low Back Pain in Student Nurses: Literature Review and Prospective Cohort Study
Authors: Menzel Nancy , Feng Du , Doolen Jessica 
Published: June 2016

AbstractThere is consensus that registered nurses worldwide have a high prevalence of work-related musculoskeletal disorders, particularly of the back. Patient handling activities such as lifting present the highest risk of injury, activities that begin in nursing school. A literature review identified 21 studies of back pain in nursing students, indicating a wide range of prevalence rates. A prospective cohort study of nursing students in a United States baccalaureate program followed 119 students who completed the Nordic Musculoskeletal Questionnaire upon beginning the 16 month upper division major and then a year later. There was no statistically significant change in low back pain prevalence over time. While nursing students have intermittent and brief exposure to patient handling activities, nursing schools must nevertheless protect them before they enter the high risk profession of nursing by teaching evidence-based safe patient handling techniques, empowering students to refuse unsafe manual lifts, and ensuring that the clinical settings with which they affiliate have adequate mechanical equipment available.
Read mapping
Authors: Hoffmann Steve , Stadler Peter F. 
Published: June 2016

Abstract
The Read Mapping problem asks for the exact origin of a nucleotide sequence in a reference genome. It translates to
a conceptually simple approximate string matching problem. The practical difficulty, however, arises from the typical size
of the data sets produced by modern high throughput sequencing technologies, from the biological processes involved in
derivation of the query molecule from its genomic source, and from the technical processes of the sequencing technology
itself.
A history of DNA sequence assembly
Authors: Myers Jr Eugene W. 
Published: June 2016

Abstract
DNA sequence assembly is a rich combinatorial problem that arose with the first DNA sequencing projects in the early 80's.
Here we give a short history of the progression of algorithmic ideas used to solve the de novo problem of
inferring a genome given a large sampling of substrings covering it. This classic inverse problem is compounded by
a variety of experimental features and artifacts that must be considered in any realistic solution. While current methods
produce very good results, the perfect assembler has yet to be built.
Stream processing platforms for analyzing big dynamic data
Authors: Hagedorn Stefan , Götze Philipp , Saleh Omran , Sattler Kai-Uwe 
Published: June 2016

Abstract
Nowadays, data is produced in every aspect of our lives, leading to a massive amount of information generated every
second. However, this vast amount is often too large to be stored and for many applications the information contained in
these data streams is only useful when it is fresh. Batch processing platforms like Hadoop MapReduce do not fit these
needs as they require to collect data on disk and process it repeatedly. Therefore, modern data processing engines combine
the scalability of distributed architectures with the one-pass semantics of traditional stream engines. In
this paper, we survey the current state of the art in scalable stream processing from a user perspective. We examine and
describe their architecture, execution model, programming interface, and data analysis support as well as discuss the
challenges and limitations of their APIs. In this connection, we introduce Piglet, an extended Pig Latin language and code
generator that compiles (extended) Pig Latin code into programs for various data processing platforms. Thereby, we discuss
the mapping to
platform-specic concepts in order to provide a uniform view.
Reconstructing single genomes from complex microbial communities
Authors: Kang Dongwan D. , Rubin Edward M. , Wang Zhong 
Published: June 2016

Abstract
High throughput next generation sequencing technologies have enabled cultivation-independent approaches to study microbial
communities in environmental samples. To date much of functional metagenomics has been limited to the gene or pathway
level. Recent breakthroughs in metagenome binning have made it feasible to reconstruct high quality, individual microbial
genomes from complex communities with thousands of species. In this review we aim to compare several automated metagenome
binning software tools for their performance, and provide a practical guide for the metagenomics research community to
carry out successful binning analyses.
Challenges ahead for matchmaking
Authors: Krawitz Peter M. 
Published: June 2016

Abstract
With every additional individual whose genome is sequenced thousands of novel variants enter the scene. It is these
variants of unknown clinical significance, VUCS, that represent a great challenge to geneticists, who are dealing with
high-throughput sequencing data sets. Especially in diagnostics of patients with unknown monogenic disease the joint
effort of geneticists is required to find new disease gene associations. For this purpose, online platforms for
matchmaking have been developed that allow clinician scientists to collaborate worldwide and to share medically relevant
data. However, for a success of these tools, skills in deep phenotyping as well as new statistical approaches will be
required.
Combining Environmental and Spatial Discount Rates for Valuation of Assets According to International Financial Reporting Standards
Authors: Jaunzeme Justine Sophia 
Published: June 2016

Abstract
Application of discount rate in finance and accounting is founded on the concept of time value of money. Discounted cash flow model is widely used for asset valuation under the International Financial Reporting Standards (in abbreviation, IFRS). The discount rate applied in valuation models normally is the best rate of return that investors would earn alternative investments. With emergence of ecological economics as a separate branch of economics, the concept of ecological (or in other words, environmental discount rate) has been elaborated. Muller (2013) in his paper ‘The Discounting Confusion: an Ecological Economics Perspective’, argues that traditional discounting can undermine long-term sustainability of the economy. In his work, Frank G. Muller considered adjusting the traditional discount rate in order to arrive at an environmental discount rate, which would help to ensure the sustainability of the economy. Hannon (2001) and Perrings (2001) in their paper ‘An Introduction to Spatial Discounting’ consider another variation of the discount rate - spatial discount rate. Spatial discount rate represents the rate at which the diffusion of environmental effects of economic activities is discounted over space. By February 2016, neither the application of environmental nor spatial discount rates under IFRS has been considered. The purpose of this paper is to analyse the implications that environmental and spatial discounting would have for the application of discounted cash flow model according to IFRS. The research methods applied are methods of economic analysis and synthesis.
Identification of Indicators’ Applicability to Settle Borrowers’ Probability of Default
Authors: Jurevičienė Daiva , Rauličkis Darius 
Published: June 2016

Abstract
Borrowers default risk is one of the most relevant types of risk in commercial banking and its assessment is important to secure business profitability and avoid huge losses during economic turbulences. This leads to necessity to investigate topics related to assessment of borrowers’ default probability and applicability of factors, which would enable to capture the newest trends of borrowers’ markets. Leading economic indicators (in addition to financial and other economic indicators) are often suggested as forward-looking in scientific literature. However, there is still a discussion going on applicability of financial ratios and economic indicators. As the problem is relevant in theoretical view as well as for practitioners, this article aims to identify applicability of leading economic indicators for the estimation of default probability. Further, the qualitative criteria for factor selection were identified and used when using detailing, grouping and SWOT analysis methods. Based on current scientific literature analysis, this paper concludes that although leading economic indicators are able to capture forward-looking signals, they should be used with careful analysis of its drawbacks and in combination with financial factors in order to avoid overshooting effects. The limitation of the article is the analysis of factors based on rather theoretical analysis than estimation of quantitative criteria. This suggests that every time using leading economic indicators requires using empirical study of particular indicators’ set.
The Role of Human Capital for National Innovation Capability in Eu Countries
Authors: Aleknavičiūtė Rasa , Skvarciany Viktorija , Survilaitė Simona 
Published: June 2016

Abstract
Innovation is essential for economic growth in developed countries. One of the most important sources of innovation is human capital. In this article, state of human capital in EU countries is investigated in order to show the relationship between human capital and national innovation performance. In the first part, theoretical assumptions of human capital importance for innovation processes are analysed. Secondly, measures of human capital are analysed and a measurement model is presented. This model is applied for investigation of state of human capital in 26 EU countries during 2002-2012. Results showed that quality of human capital is the most important factor for innovation performance. Quality indicators have even higher correlation with innovation in countries with low share of innovative enterprises (enterprises with high-level of new technology acceptance and usage). The aim of research is to analyse the theoretical importance of human capital investment for national innovation capability in EU countries, and to determine human capital aspects that foster innovation performance. Therefore, objectives are as follows: to analyse theoretical assumptions of human capital importance for innovation processes and to present the current state of research; to analyse available human capital measures and create a human capital measurement model; and to analyse state of human capital in EU countries as well as its relationship with national innovation capability.

Authors: Unger David J. 
Published: June 2016

AbstractAn exact expression is obtained for a path-dependent J-integral for finite strains of an elliptical hole subject to remote tensile tractions under the Tresca deformation theory for a thin plate composed of non-work hardening material. Possible applications include an analytical resistance curve for the initial stage of crack propagation due to crack tip blunting.
Propagation of SH waves in a regular non-homogeneous monoclinic crustal layer lying over a non-homogeneous semi-infinite medium
Authors: Sethi Munish , Sharma Arvind , Sharma Vishal , Sharma Anupamdeep 
Published: June 2016

AbstractThis study discusses the dispersion equation for SH waves in a non-homogeneous monoclinic layer over a semi-infinite isotropic medium. The wave velocity equation has been obtained. In the isotropic case, when the non-homogeneity is absent, the dispersion equation reduces to a standard SH wave equation. The dispersion curves are depicted by means of graphs for different values of non-homogeneity parameters for the layer and semi-infinite medium.
An efficient method for selecting stable tester strains of vegetative compatibility groups in Verticillium dahliae
Authors: Rataj-Guranowska Maria 
Published: June 2016

Abstract
The way compatible pairs of nitrate non-utilizing mutants (nit) are selected is usually not explained and remains unclear whether these pairs are representative for an isolate or strain. In addition, tester strains of Verticillium dahliae vegetative compatibility groups (VCGs) cross-react with at least one pair of tester strains of another VCG, and although it is a common knowledge of scientists working with the fungus that reversion of nit mutants to wild type occurs far too often, this fact is rarely mentioned in papers. To overcome the above problems, a protocol was developed for the generation of large number of nit mutants from any given isolate and to ensure that compatible pairs of mutants are indeed stable and the most frequent within the putative tester mutants produced from each isolate. Thus, we provide a reproducible and objective way of selecting V. dahliae tester strains for each isolate and VCG. Although VC grouping is based on the formation of stable heterokaryons, we demonstrate in this work that cross-reactions cannot be eliminated and that strict genetic barriers between two main VCG groups are absent in V. dahliae.
Diagnostic value of circulating tumor cells in cerebrospinal fluid
Authors: Ning Mu , Chunhua Ma , Rong Jiang , Yuan Lv , Jinduo Li , Bin Wang , Liwei Sun 
Published: June 2016

Abstract

Objective
To assess circulating tumor cells in cerebrospinal fluid as a diagnostic approach to identify meningeal metastasis in patients with non-small cell lung cancer by using tumor marker immunostaining–fluorescence in situ hybridization (TM-iFISH).

Methods
In 5 non-small cell lung cancer patients who were confirmed to have developed meningeal metastasis by cerebrospinal fluid cytology, 20 ml of cerebrospinal fluid was obtained through lumbar puncture, from which 7.5 ml was utilized for TM-iFISH to identify and quantitate circulating tumor cells, 10ml for cerebrospinal fluid cytology, and 2.5ml for detection of cerebrospinal fluid tumor markers.

Results
TM-iFISH examination identified 18 to 1,823 circulating tumor cells per 7.5ml cerebrospinal fluid. In contrast, cytology assessment revealed tumor cells in only 2 cases. The expression levels of cerebrospinal fluid tumor markers were all increased in all 5 patients when compared with their respective serum levels. Contrast-enhanced MRI scans demonstrated presence of meningeal metastasis in all 5 cases.

Conclusion
TM-iFISH may become a novel cerebrospinal fluid-based diagnostic strategy to identify circulating tumor cells and meningeal metastasis as compared to traditional diagnostic approaches, although its superior sensitivity and specificity needs to be confirmed through additional studies with a larger sample size.

Prevention and treatment of peritoneal adhesions in patients affected by vascular diseases following surgery: a review of the literature
Authors: Rocca Aldo , Aprea Giovanni , Surfaro Giuseppe , Amato Maurizio , Giuliani Antonio , Paccone Marianna , Salzano Andrea , Russo Anna , Tafuri Domenico , Amato Bruno 
Published: June 2016

Abstract
Intra-abdominal adhesions are the most frequently occurring postoperative complication following abdomino-pelvic surgery. Abdominal and pelvic surgery can lead to peritoneal adhesion formation causing infertility, chronic pelvic pain, and intestinal obstruction. Laparoscopy today is considered the gold standard of care in the treatment of several abdominal pathologies as well as in a wide range of vascular diseases. Laparoscopy has several advantages in comparison to open surgery. These include rapid recovery times, shorter hospitalisation, reduced postoperative pain, as well as cosmetic benefits. The technological improvements in this particular surgical field along with the development of modern techniques and the acquisition of specific laparoscopic skills have allowed for its wider utilization in operations with fully intracorporeal anastomoses. Postoperative adhesions are caused by aberrant peritoneal healing and are the leading cause of postoperative bowel obstruction. The use of anti-adherence barriers is currently being advocated for their prevention. The outcome of the investigation showed adhesion formation inhibition without direct detrimental effects on anastomotic healing. Poor anasto-motic healing can provoke adhesions even in the presence of anti-adhesion barriers. This review gives a short overview on the current evidence on the pathophysiology and prevention of peritoneal adhesions.
Role of FDG-PET scan in staging of pulmonary epithelioid hemangioendothelioma
Authors: Calabrese Cecilia , Gilli Marina , De Rosa Nicolina , Di Crescenzo Vincenzo , Zeppa Pio , Vitale Carolina , Vatrella Alessandro 
Published: June 2016

Abstract
In this report we describe a case of pulmonary epithelioid hemangioendothelioma (PEH) in a young woman. The neoplasm manifested with dry cough, chest pain, finger clubbing, and multiple bilateral pulmonary nodules on chest x-ray and computed tomographic (CT) scan. She underwent thoracoscopy, and the histological features of the lung biopsies were initially interpreted as consistent with a not-well-defined interstitial lung disease. Our patient was clinically and radiologically stable over a period of four years, after which the disease progressed to involve not only the lung but also mediastinal lymph nodes, liver and bone. Fiberoptic bronchoscopy showed subtotal occlusion of the right middle and lower lobe bronchi. The histologic examination of bronchial biopsies revealed a poorly differentiated neoplasm immunohistochemically positive for vimentin and vascular markers CD31, CD34 and Factor VIII. A diagnosis of malignant hemangioendothelioma was made. Positron emission tomography (PET) is more sensitive than CT scan and bone scintigraphy in detecting PEH metastases. Furthermore, 18-fluorodeoxyglucose (FDG) uptake seems to be related to the grade of malignancy of PEH lesions. Therefore, we suggest that FDG-PET should be included in the staging system and follow-up of PEH.
SOX7 inhibits tumor progression of glioblastoma and is regulated by miRNA-24
Authors: Xiuju Chen , Zhen Wang , Yanchao Shi 
Published: June 2016

Abstract

Objective
Sex-determining region Y-box 7 (SOX7) is a putative tumor suppressor in various types of human cancers. In the present study, the expression and function of SOX7 was investigated in human glioblastoma (GBM) cells.

Methods
Real-time PCR and western blot were carried out to reveal the expression of SOX7 in GBM specimens and cultured cell lines. A short interfering RNA (siRNA) targeting SOX7 was synthesized and transfected into U87 cells. 3-(4,5-Dimethylthiazol-2-yl)- 2,5-diphenyltetrazolium bromide (MTT) assay was performed to valuate the cell proliferation ability in U87 cells. Bioinformatics analysis further predicted its regulation by microRNA-24 (miR-24). Luciferase reporter assay was performed to prove this regulation.

Results
SOX7 was downregulated in GBM specimens and cell lines. Inhibition of SOX7 in cultured U87 cells resulted in a slower growth rate. Mechanically, SOX7 was a target of miR-24, demonstrated by reporter assay.

Conclusion
SOX7 was a strong tumor suppressor regulated by miR-24 in human GBM cells.
