Abstract
The objectives of the present study were twofold: to determine differences between groups by means of chosen coefficients and to create significant predictors using regression models for athletes in wheelchair rugby who had the same spinal cord injury (tetraplegia) and were classified as low point and high point players. The study sample consisted of 24 subjects, who had sustained cervical spinal cord injury (CSCI). They were divided into low point (n=15) and high point (n=9) groups according to the IWRF Classification System. A one-way ANOVA revealed statistically significant differences in the following coefficients differentiating the groups: AC (η2=0.778), LC (η2=0.687), IC (η2=0.565), SC (η2=0.580). The Tukey’s HSD post-hoc test indicated statistically significant higher values of coefficients in the HP compared to the LP group: AC=0.958 (p=0.022), LC=0.989 (p=0.031), IC=0.971 (p=0.044), SC=0.938 (p=0.039). In the HP group, the most significant predictor was the sum of visceral and trunk fat which was negatively correlated with the SC (what constituted a positive adaptive change in response to training). With regard to the LP group, body height and circumference of the chest appeared to be most significant predictors and were positively correlated with the SC. In the LP group no predictor with respect to the SC was significantly correlated to sports training. Therefore, the functional classification system confirmed lower status of the LP players. The results of the present study indicate that both metabolic and somatic profiles which highly determine potential of wheelchair rugby athletes are significantly different in LP and HP players, what confirms the reliability of the functional classification system.

Published: December 2015

Abstract
The 5th Generation of mobile networks (5G) is expected to be rolled
out by 2020. New and revolutionary applications are already being
envisioned, real-time control of machines, the Tactile Internet for
wireless, Industry 4.0, the Internet of Things and self-driving cars,
among others.
To make this possible important enhancements and improvements in
today's existing telecommunication technologies form an
end-to-end perspective are required. Early testing and fast
prototyping of new approaches and solutions will help to shape the
evolving technologies. One of the technical enablers for 5G are two
concepts based on the softwarisation and virtualisation of the core
network, known as Software Defined Networking (SDN) and Network
Function Virtualisation, NFV. Fraunhofer FOKUS has set up the
Open5GCore testing environment to start shaping, together with its
partners, the nascent 5G technologies by addressing these topics
together with other relevant technological developments. After a short
motivation, the architecture of the open5GCore is presented, followed
by a functional description of supported features.

Published: December 2015

Abstract
The introduction of Software Defined Networking (SDN) and Network
Functions Virtualization (NFV) has transformed the way networks will
be built in the future. This development also applies to mobile
networks and their evolution. How the SDN and NFV concepts will be
integrated exactly is still an open research question with multiple
approaches and techniques in discussion. This article provides an
overview of the current discussion points with regard to development
paths, building blocks, deployment scenarios, and the opportunities
and challenges of the new concepts in the mobile core network
context.
Softwarization of telecommunications
Authors: Manzalini Antonio 
Published: December 2015

Abstract
This paper argues that SDN and NFV principles are going to impact not
only the evolution of current networks, but also the services and
applications platforms. In fact, SDN and NFV, together with Cloud and
Edge Computing, can be seen as facets of a broader systemic innovation
wave (called softwarization) which is transforming the overall
telecommunications and ICT ecosystems. Specifically, the paper
proposes the vision of Software Defined Infrastructures (SDI) as
highly dynamic and pervasive telecommunications and ICT frameworks of
logical resources capable of executing (with a trade-off of
centralisation and distribution) any network and service
functions. Eventually, it is argued that, in this evolution towards
SDI, the border between the networks and the Cloud-Edge Computing
platforms will gradually disappear. On the other side, also the
distinction between the networks and the future “terminals”
(e. g., including machines, smart things, drones, robot) will
blur. This transformation will have profound techno-economic
implications for the telecommunications and ICT ecosystems, paving the
way to the Digital Society and the Digital Economy.
Can open-source projects (re-)shape the SDN/NFV-driven telecommunication market?
Authors: Tavernier Wouter , Naudts Bram , Colle Didier , Pickavet Mario , Verbrugge Sofie 
Published: December 2015

Abstract
Telecom network operators face rapidly changing business needs. Due to their dependence on long product cycles they lack the ability to
quickly respond to changing user demands. To spur innovation and stay
competitive, network operators are investigating technological
solutions with a proven track record in other application domains such
as open source software projects. Open source software enables parties
to learn, use, or contribute to technology from which they were
previously excluded. OSS has reshaped many application areas including
the landscape of operating systems and consumer software. The paradigm
shift in telecommunication systems towards Software-Defined Networking
introduces possibilities to benefit from open source
projects. Implementing the control part of networks in software
enables speedier adaption and innovation, and less dependencies on
legacy protocols or algorithms hard-coded in the control part of
network devices. The recently proposed concept of Network Function
Virtualization pushes the softwarization of telecommunication
functionalities even further down to the data plane. Within the NFV
paradigm, functionality which was previously reserved for dedicated
hardware implementations can now be implemented in software and
deployed on generic Commercial Off-The Shelf (COTS) hardware. This
paper provides an overview of existing open source initiatives for
SDN/NFV-based network architectures, involving infrastructure to
orchestration-related functionality. It situates them in a business
process context and identifies the pros and cons for the market in
general, as well as for individual actors.
Virtualization of residential customer premise
equipment. Lessons learned in Brazil vCPE trial
Authors: Cantó Palancar Rafael , López da Silva Rafael Alejandro , Folgueira Chavarría Jesús Luis , López Diego R. , Elizondo Armengol Antonio J. , Gamero Tinoco Ruth 
Published: December 2015

Abstract
This paper presents Telefónica approach for virtualizing
residential customer premises equipment (vCPE), showing how the
equipment at a customer's home can be simplified and how the
management of resources and services improves as
a result. This use case of virtualization enables the operator to
shift most functions from the residential gateways towards the carrier
own network, by running them on general-purpose servers at the
operator premises. This makes it possible that network functions such
as IP routing, IP address management (DHCP), address translation (NAT), firewall, Set Top Box functionalities (live TV,
VoD, etc.), etc. are maintained and
upgraded from the most efficient location. Because of the expected
high impact onto the economics of the Telco network operations, the
virtualization of the CPE is considered by the authors as one
promising use case of Network Virtualization technologies. The virtual
CPE approach is being tested in Brazil (where Telefónica operates
under the Vivo brand), and represents a great opportunity for learning
lessons on development and deployment of Virtual Network Functions
(VNFs). Some of them are summarized in this
paper.
State-Sponsored Sacrilege: “Godnapping” and Omission in Neo-Assyrian Inscriptions
Authors: Zaia Shana 
Published: December 2015

AbstractBecause of the symbolic and religious importance of cult statues in ancient Mesopotamia, these images were targeted on numerous occasions by invading forces as part of the conquest of a foreign polity. In the case of the Assyrians, triumphant kings would sometimes list cult statues from a newly-conquered city or group as spoils of war, alongside members of the royal family, their subjects, and their precious goods. Such acts of divine deportation are sometimes called “godnapping” in secondary literature. A conspicuous feature in godnapping reports is the paucity of divine names mentioned. Deported cult images are instead simply called “gods” of a foreign king, people, or city. Because godnapping has thus far been studied purely as a political tactic, the omission of names has been ascribed to the Assyrians’ disinterest in or ignorance of non-Assyrian divinities. This study proposes viewing godnapping not through a political lens but rather a religious one, arguing that the Assyrians would certainly have been aware of which cult statues they were deporting, and that they would have considered the non-Assyrian cult images gods in their own right. Focusing upon the religious and inscriptional traditions of the Assyrians, this paper seeks to demonstrate that omitting divine names in deportation accounts may have been purposeful and meant to prevent these gods from seeking retribution. Instead of using the traditional approach of examining the political ramifications for the conquered polity whose gods have been deported, this paper turns instead to the religious and psychological consequences for those who were deporting the gods and exposes the Assyrian perspective of godnapping as presented in their own inscriptions.
Phenotypic variations in osmotic lysis of Sahel goat erythrocytes in non-ionic glucose media
Authors: Igbokwe Nanacha Afifi , Igbokwe Ikechukwu Onyebuchi 
Published: December 2015

Abstract

Background: Erythrocyte osmotic lysis in deionised glucose media is regulated by glucose influx, cation efflux, and changes in cell volume after water diffusion. Transmembrane fluxes may be affected by varied expression of glucose transporter protein and susceptibility of membrane proteins to glucose-induced glycosylation and oxidation in various physiologic states.

Methods: Variations in haemolysis of Sahel goat erythrocytes after incubation in hyposmotic non-ionic glucose media, associated with sex, age, late pregnancy, and lactation, were investigated.

Results: The osmotic fragility curve in glucose media was sigmoidal with erythrocytes from goats in late pregnancy (PRE) or lactation (LAC) or from kid (KGT) or middle-aged (MGT) goats. Non-sigmoidal phenotype occurred in yearlings (YGT) and old (OGT) goats. The composite fragility phenotype for males and non-pregnant dry (NPD) females was non-sigmoidal. Erythrocytes with non-sigmoidal curves were more stable than those with sigmoidal curves because of inflectional shift of the curve to the left. Erythrocytes tended to be more fragile with male than female sex, KGT and MGT than YGT and OGT, and LAC and PRE than NPD. Thus, sex, age, pregnancy, and lactation affected the haemolytic pattern of goat erythrocytes in glucose media.

Conclusions: The physiologic state of the goat affected the in vitro interaction of glucose with erythrocytes, causing variations in osmotic stability with variants of fragility phenotype. Variations in the effect of high extracellular glucose concentrations on the functions of membrane-associated glucose transporter, aquaporins, and the cation cotransporter were presumed to be relevant in regulating the physical properties of goat erythrocytes under osmotic stress.
Synthetic Environments for Investigating Collaborative Information Seeking: An Application in Emergency Restoration of Critical Infrastructures
Authors: Mendonça David , Wallace William A. , Cutler Barbara , Brooks James 
Published: December 2015

AbstractLarge-scale disasters can produce profound disruptions in the fabric of interdependent critical infrastructure systems such as water, telecommunications and electric power. The work of post-disaster infrastructure restoration typically requires information sharing and close collaboration across these sectors; yet – due to a number of factors – the means to investigate decision making phenomena associated with these activities are limited. This paper motivates and describes the design and implementation of a computer-based synthetic environment for investigating collaborative information seeking in the performance of a (simulated) infrastructure restoration task. The main contributions of this work are twofold. First, it develops a set of theoretically grounded measures of collaborative information seeking processes and embeds them within a computer-based system. Second, it suggests how these data may be organized and modeled to yield insights into information seeking processes in the performance of a complex, collaborative task. The paper concludes with a discussion of implications of this work for practice and for future research.

at 15 locations using T-type thermocouples. Alumina and CuO nanoparticles
were synthesized and characterized using Brunauer–Emmett–Teller and X-ray
diffraction techniques and dispersed using ultrasonic mechanism.

water and used in the solar flat-plate collector. The temperature profile
was compared with different volume fractions of the nanoparticles in the
flowing medium. Enhanced heat transfer was observed in the solar flat-plate
collector using nanoparticles, and hence, it is inferred that addition of
nanoparticles improves the efficiency of the solar water heaters.
This paper details the temperature profile observed in the collectors, variation of
insolation over the day, and change in efficiency both on the primary side
(collector) and on the secondary side (storage tank) of the solar water heater.
Using Text Models In Diagnostic Tasks.
Authors: Korostil Yuriy , Korostil Olga 
Published: December 2015

Abstract
This paper contains developing of a method of solving diagnostic tasks for complex technical objects (STO) based on using text models (TMi) to describe the functioning of STO. A TMi model is a text description, in normalized form, of all fragments of STO functioning process. The description of TMi is for med using semantic vocabularies of different types, which are generated on the basis of usage of information about all the aspects of STO construction and functioning. Such interpretation description is a subject area for tasks of STO diagnostics. Detection of malfunction and deviations of a functioning process of STO from an established functioning mode is implemented on the basis of analysis of semantic parameters of text description of the STO functioning process in order to determine semantic anomalies which occur in the descriptions of the STO functioning process, as well as in the descriptions of fragments of its functioning. Semantic anomalies occur in case when values of semantic parameters go beyond their established limits.

This article applies diagnosing issues outflows of gas pipelines using specialized research equipment - equalizers. Variant with only two measuring devices (equalizers), arranged on the inlet and outlet of the pipeline, and the standard pressure transducers and flow rate were considered. The signals from the system and research equipment (equalizers) are the basis for the development of new method to test outflow of gas pipeline, which is based on the quotient of the power spectral density of signals generated by the equalizer (diagnoser) and signals measured using standard pressure transducers and flow rate. Possible use to analysis the signals power will allow go from signal diagnostic for more effective parametric diagnostic.

Authors: Oskarbski Jacek , Jamroz Kazimierz 
Published: December 2015

Abstract
Technologies that use transport telematics offer tools for strengthening urban transport systems. They rationalise the use of the existing infrastructure and transport management systems, increase their reliability and safety and improve the transport behaviour of residents, while reducing the operating costs of transport. The main reason for using Intelligent Transport Systems (ITS) is the need to implement measures to reduce the negative effects of growing motorization and improve the quality of transport services in response to the fluctuating transport demand. The authors present ways to improve the reliability and safety of transport in the street network by using ITS solutions.
Role of nutrition in preventing insulin resistance in children
Authors: Blasetti Annalisa , Franchini Simone , Comegna Laura , Prezioso Giovanni , Chiarelli Francesco 
Published: December 2015

AbstractNutrition during prenatal, early postnatal and pubertal period is crucial for the development of insulin resistance and its consequences. During prenatal period fetal environment and nutrition seems to interfere with metabolism programming later in life. The type of dietary carbohydrates, glycemic index, protein, fat and micronutrient content in maternal nutrition could influence insulin sensitivity in the newborn. The effects of lactation on metabolism and nutritional behavior later in life have been studied. Dietary habits and quality of diet during puberty could prevent the onset of a pathological insulin resistance through an adequate distribution of macro- and micronutrients, a diet rich in fibers and vegetables and poor in saturated fats, proteins and sugars. We want to overview the latest evidences on the risk of insulin resistance later in life due to both nutritional behaviors and components during the aforementioned periods of life, following a chronological outline from fetal development to adolescence.
The shortened combined clonidine and arginine test for growth hormone deficiency is practical and specific: a diagnostic accuracy study
Authors: Al Khalifah Reem , Moisan Lina , Bui Helen 
Published: December 2015

Abstract

Background: The growth hormone (GH) stimulation protocols for clonidine and arginine tests are non-standardized and can be lengthy. We examined the specificity of both tests using a shorter duration of timed samples: 90 min for clonidine and 60 min for arginine.

Methods: We retrospectively studied all children who had GH stimulation with clonidine and arginine to test for GH deficiency (GHD). We compared the diagnostic accuracy of both reference and new shortened test (index).

Results: We reviewed 243 charts (11.4±4.1 years old; 74.5% males). The combined reference test was performed on 159 children, 29 (18.3%) tested positive for GHD on the combined index test, Kappa 0.98, false positive rate 1 (0.8%), specificity 0.99, 95th CI (0.96–1), and p=1.0. The specificity of both the clonidine and arginine single index tests was 0.98%.

Conclusions: The shortened clonidine and arginine stimulation index tests have good specificity. This is a viable option for testing children for GHD.
Positron annihilation in liquid crystals
Authors: Dryzek Ewa , Juszyńska-Gałązka Ewa 
Published: December 2015

Abstract
Positron annihilation studies of liquid crystals are reviewed with particular reference to thermotropic liquid crystals with rod-like molecules. The studies of compounds exhibiting smectic A or smectic E phases indicate that local arrangement of dipole molecules play an important role because high electron density at the end group of molecules can influence substantially formation and annihilation of positronium. The obtained ortho-positronium lifetimes in these phases can be explained by antiparallel pairing of molecules in case of the smectic A phase or a structure with a nanosegregation of alkyl chains and others parts of molecules into sublayers and liquid-like state of alkyl chains in case of the smectic E phase.
Positron annihilation studies of high-manganese steel deformed by rolling
Authors: Dryzek Ewa , Sarnek Maciej , Wróbel Mirosław 
Published: December 2015

Abstract
Positron annihilation spectroscopy (PAS) has been used to study the annealing behavior of cold rolled Fe – 21 wt% Mn steel with 0.05 wt% C. After the initial annealing of defects shown by Doppler broadening of the annihilation line, a slight increase in the annihilation line shape parameter, i.e., the so-called S parameter and then its decrease in the temperature range between 225°C and 450°C indicates generation of new defects and their subsequent annealing. This temperature range coincides with X-ray diffraction measurements, which indicate reversion of deformation-induced ε-martensite. However, for annealing in this temperature range with slow cooling of the sample, the formation of ferrite already starts. The results are compared with our previous results for deformed austenitic stainless steel 1.4301 (EN) where only reversion of deformation-induced α′-martensite was detected.

Abstract
In this paper, we present prospects for using the Jagiellonian positron emission tomograph (J-PET) detector to search for discrete symmetries violations in a purely leptonic system of the positronium atom. We discuss tests of CP and CPT symmetries by means of ortho-positronium decays into three photons. No zero expectation values for chosen correlations between ortho-positronium spin and momentum vectors of photons would imply the existence of physics phenomena beyond the standard model. Previous measurements resulted in violation amplitude parameters for CP and CPT symmetries consistent with zero, with an uncertainty of about 10−3. The J-PET detector allows to determine those values with better precision, thanks to the unique time and angular resolution combined with a high geometrical acceptance. Achieving the aforementioned is possible because of the application of polymer scintillators instead of crystals as detectors of annihilation quanta.
