Enabling Key Technologies and Emerging Research Challenges Ahead of 5G Networks: An Extensive Survey

The evolution towards 5G networks is expected to slake the growing thirst of internet traffic with improved Quality of Service (QoS) and reduced energy consumption and cost. The increased penetration of smart devices and induction of arising multimedia applications, together with high quality video services are already crafting a milestone on existing cellular networks. These surging demands dictate that radical enhancements need to be made in cellular architecture to drift towards ultra-dense networks. The 5G system is envisioned to achieve improved data rate, increased capacity, decreased latency, and enhanced spectral efficiency in order to provide technical solution for the challenges behind the cellular networks. Thus, the 5G era is emerging to quench the increasing demand for network capacity, to manage explosive growth of traffic patterns and to face the challenges caused by the proliferation of versatile applications and high-end devices. In this paper, we make a broad survey on 5G cellular network architecture and some of the promising key technologies such as cloud RAN (Radio Access Network), Software-Defined Networking (SDN), Network Function Virtualization (NFV) and modulation formats. Finally, this ground-breaking survey highlights major existing research issues and possible future research directions in the next new era of mobile wireless networks.
Adaptive Range Counting and Other Frequency-Based Range Query Problems

We consider variations of range searching in which, given a query range, our goal is to compute some function based on frequencies of points that lie in the range. The most basic such computation involves counting the number of points in a query range. Data structures that compute this function solve the well-studied range counting problem. We consider adaptive and approximate data structures for the 2-D orthogonal range counting problem under the w-bit word RAM model. The query time of an adaptive range counting data structure is sensitive to k, the number of points being counted. We give an adaptive data structure that requires O(n log log n) space and O(log log n+logw k) query time. Nonadaptive data structures on the other hand require Ω(logw n) query time (Pătrascu, 2007). Our specific bounds are interesting for two reasons. First, when k = O(1), our bounds match the state of the art for the 2-D orthogonal range emptiness problem (Chan et al., 2011). Second, when k = Θ(n), our data structure is tight to the aforementioned Ω(logw n) query time lower bound. We also give approximate data structures for 2-D orthogonal range counting whose bounds match the state of the art for the 2-D orthogonal range emptiness problem. Our first data structure requires O(n log log n) space and O(log log n) query time. Our second data structure requires O(n) space and O(log n) query time for any fixed constant > 0. These data structures compute an approximation k′ such that (1− δ)k ≤ k′ ≤ (1 + δ)k for any fixed constant δ > 0. The range selection query problem in an array involves finding the k lowest element in a given subarray. Range selection in an array is very closely related to 3-sided 2-D orthogonal range counting. An extension of our technique for 3-sided 2-D range counting yields an efficient solution to adaptive range selection in an array. In particular, we present an adaptive data structure that requires O(n) space and O(logw k) query time, exactly matching a recent lower bound (Jorgensen and Larsen, 2011). We next consider a variety of frequency-based range query problems in arrays. We give efficient data structures for the range mode and least frequent element query problems and also exhibit the hardness of these problems by reducing Boolean matrix multiplication to the construction and use of a range mode or least frequent element data structure. We also give data structures for the range α-majority and α-minority query problems. An α-majority is an element whose frequency in a subarray is greater than an α fraction of the size of the subarray; any other element is an α-minority. Surprisingly, geometric insights prove to be useful even in the design of our 1-D range α-majority and α-minority data structures.
The Prevalence of Osteoporosis in the Thrace Region of Turkey: A Community-Based Study Türkiye'nin Trakya Bölgesinde Osteoporoz Prevalansi: Toplum Temelli Bir Çalişma

Objective: This study was planned as a community-based research study to estimate the prevalence of osteoporosis and explore related risk factors in the Thrace region of Turkey. Material and Methods: The community-based study involved a total of 620 people, 498 women and 122 men, aged between 40 and 89 years. A questionnaire on the medical history and lifestyles of the participants was applied with a face-to-face interview. Body weight height, and arm span of each participant were measured, together with bone mineral density at the middle phalanges of the second, third, and fourth digits of the non-dominant hand using dual-energy X-ray laser absorptiometry. Results: Age, clothing, lack of regular exercise, and giving birth to more than two children seem to contribute to osteoporosis, while high education, high economic level, tea and moderate alcohol consumption, oral contraceptive use, and hormone replacement therapy seem to retard osteoporosis. Osteoporotic patients had more fractures in the past. Height and weight were significantly lower in osteoporotic women. Conclusion: Lifestyle affects the prevalence of osteoporosis. Drinking tea and alcohol seems to be controversial with regard to osteoporosis risk.
Selection of the optimum prime mover and the working fluid in a regenerative organic rankine cycle

A regenerative organic Rankine cycle (RORC) is modeled and optimized for the use of waste heat recovery from a prime mover (PM). Three PMs including, a diesel engine, a gas engine, and a microturbine are selected in this study. Four refrigerants including isobutane, R123, R134a, and R245fa are selected. The nominal capacity of the PM, PM operating partial load, turbine inlet pressure, condenser pressure, refrigerant mass flow rate, pump efficiency, turbine efficiency, and regenerator effectiveness are considered as the decision variables. Then, the Genetic Algorithm is applied to maximize the thermal efficiency and minimize the total annual cost (TAC), simultaneously. The optimum results demonstrate that the best working fluid and the PM are, respectively, R123 and the diesel engine, which have a thermal efficiency of 0.50 and a TAC of $170,276/year. The optimum results are compared with each of the other studied cases. For example, the optimum result in the case of a diesel engine working with R123 shows a 2% and 2.52% improvement in the thermal efficiency and the TAC, respectively, in comparison to the case of a gas engine working with R123. Furthermore, a 26% and an 18.38% improvement in the thermal efficiency and the TAC are found when the best-studied cycle is compared with a microturbine and R123.
Compensation Strategy for the Future Force

Abstract : The Assistant Deputy Chief of Naval Operations, Manpower and Personnel (N1B) requested that CNA analyze the Navy's compensation system in view of current recruiting and manning shortfalls and anticipated future changes in the Navy's workforce. This study will help the Navy implement an effective, market-based compensation system that will give it the ability to attract, retain, and motivate a high-quality workforce in a competitive, dynamic labor market. The intent is to take a strategic look at Navy compensation policy and practices. The starting point is to consider what the Navy wants to accomplish with its compensation system. What goals, in terms of managing human resources, can be met through compensation policies and practices? We consider human resources management system approaches, as well as approaches suggested by economics literature, and arrive at a succinct set of strategic goals.
Expression of Mycobacterium tuberculosis Protein Tyrosine Phosphatase B in Escherichia coli and Its Recovery from Inclusion Body

The present study aims at expressing and partially purifying PtpB in active form. To achieve this, Mtb PtpB gene has been cloned into pET30a vector and overexpressed in Escherichia coli BL 21(DE3) under IPTG induction in the form of an inclusion body. Following resolubilization by urea and dialysis, the resulted PtpB has been shown to be active against para-Nitrophenyl phosphate. It is concluded that the resulted PtpB has had been recovered from inclusion body to give the active form of the enzyme, and thus the success in overexpressing PtpB provides the required material to investigate the biochemical properties of the pathogen virulence factor
TRATAMENTO DAS DOENÇAS PERIIMPLANTARES: MUCOSITE E PERIIMPLANTITE - PARTE 1: TERAPIA ANTIINFECCIOSAof peri-implant diseases: mucositis and peri-implantitis. Part 1: Antiinfective therapy

RESUMO Os implantes de titânio osseointegrados tem sido amplamente utilizados para reabilitacao de pacientes edentulos. Entretanto, associado ao aumento da demanda dos implantes osseointegrados, um aumento no numero de complicacoes periimplantares tambem tem sido observado. Dentre essas complicacoes, os processos infecciosos mucosite e periimplantite podem comprometer a longevidade da reabilitacao por implantes. Ambas as doencas apresentam caracteristicas clinicas e microbiologicas semelhantes as doencas periodontais, como a presenca de especies bacterianas patogenicas (Porphyromonas gingivalis, Treponema denticola e Tannerella forsythia), sangramento a sondagem, formacao de bolsas e supuracao. Para reduzir o numero de patogenos e melhorar o perfil clinico ao redor de implantes doentes, diversas terapias antiinfecciosas tem sido propostas. O debridamento em campo fechado parece nao ser efetivo para tratamento da periimplantite. Porem, a associacao de antibioticos sistemicos ou locais pode melhorar o resultado desta terapia. Similarmente, a descontaminacao em campo aberto produz beneficios clinicos e microbiologicos no tratamento da periimplantite. Entretanto, estudos clinicos controlados que realizem comparacoes diretas entre as diversas terapias ainda precisam ser conduzidos para a obtencao de um protocolo terapeutico ideal para essas infeccoes.

A structural approach towards perceptions and satisfaction of revisit intentions

This paper identifies the key antecedents of revisit intentions to Western Australia’s (WA) South-West Region. Four antecedents namely, perceived attractiveness, quality, value and risk are examined. Consumer satisfaction is proposed to mediate the relationship between these antecedents and revisit intentions to WA’s South-West Region. A research model is developed together with an agenda of five hypotheses. The findings suggest that perceived attractiveness, quality and value are significant predictors of consumer satisfaction and subsequently, revisit intentions. In conclusion, some managerial implications for destination managers and tourism operators are outlined to help them better understand tourists’ destination choices, while a few limitations are noted for future research.
DSOGI-PLL Based Power Control Method to Mitigate Control Errors Under Disturbances of Grid Connected Hybrid Renewable Power Systems

The control of power converter devices is one of the main research lines in interfaced renewable energy sources, such as solar cells and wind turbines. Therefore, suitable control algorithms should be designed in order to regulate power or current properly and attain a good power quality for some disturbances, such as voltage sag/swell, voltage unbalances and fluctuations, long interruptions, and harmonics. Various synchronisation techniques based control strategies are implemented for the hybrid power system applications under unbalanced conditions in literature studies. In this paper, synchronisation algorithms based Proportional-Resonant (PR) power/current controller is applied to the hybrid power system (solar cell + wind turbine + grid), and Dual Second Order Generalized Integrator-Phase Locked Loop (DSOGI-PLL) based PR controller in stationary reference frame provides a solution to overcome these problems. The influence of various cases, such as unbalance, and harmonic conditions, is examined, analysed and compared to the PR controllers based on DSOGI-PLL and SRF-PLL. The results verify the effectiveness and correctness of the proposed DSOGI-PLL based power control method.
Design, Dynamics, and Workspace of a Hybrid-Driven-Based Cable Parallel Manipulator

The design, dynamics, and workspace of a hybrid-driven-based cable parallel manipulator (HDCPM) are presented. The HDCPM is able to perform high efficiency, heavy load, and high-performance motion due to the advantages of both the cable parallel manipulator and the hybrid-driven planar five-bar mechanism. The design is performed according to theories of mechanism structure synthesis for cable parallel manipulators. The dynamic formulation of the HDCPM is established on the basis of Newton-Euler method. The workspace of the manipulator is analyzed additionally. As an example, a completely restrained HDCPM with 3 degrees of freedom is studied in simulation in order to verify the validity of the proposed design, workspace, and dynamic analysis. The simulation results, compared with the theoretical analysis, and the case study previously performed show that the manipulator design is reasonable and the mathematical models are correct, which provides the theoretical basis for future physical prototype and control system design.
FROM DUSK OF THE INFORMATION ERA TO DAWN OF THE EXPERIENCE ERA: VIDEOGAMES AS A LEARNING TOOL

Knowledge institutions are often distracted by themselves and unable to understand what happens in the world of cultural consumption. the videogame, for example, is quite different from all other media forms, owning its peculiar language, the gameplay: an interactive, experiential participation which guarantees a form of involvement that no other medium has. If every medium carries an educational potential, the use of video-games as a learning tool still remains largely undefined. To implement video game within the educational system may look like a radical revolution. We should try different solutions: the so called “gamification” approach, using videogame dynamics within our common educational framework or “Simulation Based Learning” using virtual worlds in which teachers and students can simulate experiences by their own rules. Experience based Learning provided by video games may become the ultimate form of contextual education. It is able to simulate a real-life experience, improving both student engagement and learning. We have to look at the games as a tool, whose value in education depends on how they are used as part a comprehensive strategy. The traditional methods of education are focused on the acquisition of skills in the individual subjects, often neglecting crucial components for success, such as communication and collaboration. I try to define an optimal, real-life solution that decreases the centrality of the written medium, currently at the base of the educational system, merging and integrating it with new tools and techniques, adding to the traditional literacy processes a renewed techno-literacy, necessary for students to communicate and learn.
Structure of CaO–B2O3–SiO2–TiO2 Glasses: a Raman Spectral Study

Development and application of fluorine free mould fluxes have been widely studied in recent years. Some research has shown that B2O3 and TiO2 are potential substitutes for F– in mold fluxes. In this study, Structure of CaO–B2O3–SiO2–TiO2 glass system has been studied by Raman spectroscopy. The influence of basicities (CaO/SiO2) and contents of B2O3 and TiO2 on the structure of CaO–B2O3–SiO2–TiO2 glasses were examined. Experimental results indicate that TiO2 exists in the system in the form of [TiO4] as network former in range of 0–15% in mass. The degree of polymerization of this system decreases with increase of basicities. The increase of B2O3 leads to more [BO4] tetrahedral units. It is concluded that both B2O3 and TiO2 behave as network forming oxides within the studied system.
Exploring the Interpersonal Meaning in two extracts from Chimamanda Ngozi Adichie’s Purple Hibiscus and Chinua Achebe’s Anthills of the Savannah : A Comparative Systemic Functional Linguistic Perspective

Abstract This paper examines Mood Patterns in some passages from Adichie’s Purple Hibiscus and Achebe’s Anthills of the Savannah. More specifically, two extracts from the above mentioned prose fiction have been purposefully selected, described and analyzed from the Systemic Functional Linguistics perspective in order to reveal how the lexicogrammatical features of the interpersonal meaning of the studied extracts underpin the perception of the two authors throughout their novels. The article goes further and highlights the similarities and differences in the interpersonal functions of the extracts under scrutiny in terms of their contents and how the English language has been used therein to construe the above pinpointed authors’ world views of the issues dealt with in their writings. The findings of the study have, among others, revealed that the gap between Achebe’s and Adichie’s writings is not full size and that the former has actually paved the way to the latter.
Recombinant vaccine production in green plants: State of art

Green plants have emerged as ideal platforms for production of recombinant vaccine during recent decades. Various antigens relating to a large number of animal and human diseases have been studied in different plant species for production of recombinant vaccines. Despite the unique advantages of plant systems as green factories for production of recombinant vaccines, there are some major hurdles that have prevented commercial production of plant-based vaccines. In this review, theoretical background and practical applications of plant system for production of various recombinant vaccines are discussed.
Are differing forms of innovation complements or substitutes

Purpose – The purpose of this paper is to provide an empirical analysis of whether differing forms of innovation act as complements or substitutes in Irish firms’ production functions.Design/methodology/approach – The approach adopted by this paper is empirical in nature. Data are obtained for approximately 582 firms from the Irish Community Innovation Survey 2004‐2006. In total, four forms of innovation activity are identified: new to firm product, new to market product, process and organisational innovation. Formal tests for complementarity and substitutability are applied to these types of innovation to assess whether they have a complementary effect on firms’ turnover.Findings – The results suggest that there is a substantial degree of complementarity among different forms of innovation. Out of six possible innovation combinations, three are complementary while none exhibits signs of substitutability.Social implications – From a business perspective, the importance of organisational change to facilita.

Vulnerability to robbery can transform workers’ relationship with their work. The aim of this research was to characterize the organizational and behavioral consequences of workplace robberies in the perception of victimized workers. Semi-structured interviews were carried out with seven workers. The data were analyzed through content analysis, in two axes of analysis: organizational consequences and behavioral consequences. The installation of monitoring cameras, the management of money in the cash register, and caution when closing and leaving the workplace were the main organizational consequences. Intensified attention, occupational disinterest, emotional changes, and religious behavior were the main behavioral consequences identified. It is concluded that the robbery experience can re-signify the meaning of the work, and there is a need for new research that makes it possible to explain and create conditions for this kind of suffering to be accommodated and managed in the organizations and locations for worker health care. Las consecuencias del atraco al trabajador del comercio victimizado Resumen La vulnerabilidad a los atracos puede transformar la relación del trabajador con el trabajo. El objetivo de esta investigación fue caracterizar la percepción de los trabajadores victimizados acerca de las consecuencias organizativas y comportamentales del atraco. Se realizaron entrevistas semiestructuradas con siete trabajadores. Los datos fueron analizados por medio de análisis de contenido, en dos ejes de análisis: consecuencias organizativas y consecuencias comportamentales. La instalación de cámaras de monitoreo, la gestión del dinero en la caja y el cuidado al cerrar y salir de la empresa fueron las principales consecuencias organizativas. La atención intensificada, desinterés ocupacional, alteración emocional y comportamiento religioso fueron las principales consecuencias comportamentales identificadas. Se concluye que la experiencia de atraco puede resignificar el significado del trabajo, habiendo necesidad de nuevas investigaciones que viabilicen explicar y crear condiciones para que ese tipo de sufrimiento sea acogido y manejado en las organizaciones y locales de cuidado a la salud del trabajador. 1 Endereço para correspondência: Coordenação do curso de Psicologia, Avenida Pedra Branca, no 25, Cidade Universitária Pedra Branca, 88137-272, Palhoça, SC Brasil.

Brown ring disease in the Manila clam Ruditapes philippinarum: establishment of a classificaiton system

The main sign characterizing brown ring disease (BRD) in Manila clam Ruditapesphilippinarum is a brown conchiolin deposit on the inner surface of the shell. Different stages of deposit formation and of the shell repair process were examined by means of binocular microscopy. The surface area of the deposit was quantrfied by lmage analysis and its precise location was determined. Experimental induction of brown ring syndrome after infection with a Vibrio sp. (VP1) allowed us to follow the evolution of macroscopic modifications in the shell inner surface. Simultaneously with the development of BRD, a shell repair process generally occurs. Based on these macroscopic observations, a classification of BRD is proposed.
COVERED TRAY SSF AND HYDROPONICS LIKE SSF -NOVEL ALTERNATIVE METHODS TO THE CONVENTIONAL SOLID STATE FERMENTATION

The work was focused at developing new methods, the Covered -Tray and Hydroponics-like solid state fermentation (CT SSF and HP-SSF) and comparing them with conventional solid state fermentation in trays (T -SSF) for the extracellular protease production by Aspergillus flavus (NCIM 535) using wheat bran. The Revolving Drum SSF method, an available alternative to T -SSF, was used as a positive control. The protease production using CT -SSF was equivalent to that using the T-SSF whereas the HP-SSF presented a high ly significantly more production (p "d0.002) and hence was selected for further optimization. Univariate optimization of the selected process parameters of HP -SSF and T-SSF followed the Plackett-Burman method for the determination of the three most significa nt process parameters. Using the central composite design contour plots for their interaction in pairs was obtained to determine the optimized yield. A novel stepwise supplementation method for nitrogen during the incubation enhanced the protease productio n by 82 % against the 31 % increase in a single dose manner traditionally practiced. Altering the moisture level on different days of incubation revealed a distinct phase wise requirement of it. Scale up of the method was done to 10 and 100 fold levels and the
