Despite of intensive investigations on transportation dynamics taking place on complex networks with fixed structures, a deep understanding of networks consisting of mobile nodes is challenging yet, especially the lacking of insight into the effects of routing strategies on transmission efficiency. We introduce a distance-based routing strategy for networks of mobile agents toward enhancing the network throughput and the transmission efficiency. We study the transportation capacity and delivering time of data packets associated with mobility and communication ability. Interestingly, we find that the transportation capacity is optimized at moderate moving speed, which is quite different from random routing strategy. In addition, both continuous and discontinuous transitions from free flow to congestions are observed. Degree distributions are explored in order to explain the enhancement of network throughput and other observations. Our work is valuable toward understanding complex transportation dynamics and designing effective routing protocols.

Network Coding is used to increase network throughput. In the network coding, network data packets will be encoded by the sender and the encoded data packets can be used by different receivers to recovery the same original data packets. This increases the network transmission efficiency. Coding on data will consume the computing resources and this becomes the bottleneck of network codings practicability. In this paper, we assume that the coding happens at the end of the network and we conduct some tests on the pc and hand-devices. Our results show that network coding can work well on current PC, and we need a native device support to make the network coding working on the hand-devices.

Outcome Differences

Sex differences have been well identified in many brain tumors. Even though glioblastoma (GBM) is the most common primary malignant brain tumor in adults and has the worst outcome, well-established differences between men and women are limited to incidence and outcome. Little is known about sex differences in GBM at the disease phenotype and genetical/molecular level. This review focuses on a deep understanding of the pathophysiology of GBM, including hormones, metabolic pathways, the immune system, and molecular changes, along with differences between men and women and how these dimorphisms affect disease outcome. The information analyzed in this review shows a greater incidence and worse outcome in male patients with GBM compared with female patients. We highlight the protective role of estrogen and the upregulation of androgen receptors and testosterone having detrimental effects on GBM. Moreover, hormones and the immune system work in synergy to directly affect the GBM microenvironment. Genetic and molecular differences have also recently been identified. Specific genes and molecular pathways, either upregulated or downregulated depending on sex, could potentially directly dictate GBM outcome differences. It appears that sexual dimorphism in GBM affects patient outcome and requires an individualized approach to management considering the sex of the patient, especially in relation to differences at the molecular level.

Startups, as they are bounded to their liabilities of newness and smallness, need to collaborate extensively with their external partners through the open innovation process. This study aims to depict Co-working space's pivotal role in building up a working innovation ecosystem that facilitates open innovation for startups. To get a more deep understanding of the phenomena, this study used an exploratory study based on three case studies of Co-working spaces operated in the Jakarta region. The study shows that the open innovation process among startups is not naturally existed, but instead, it is purposefully designed by the role of a community manager who acts as the ecosystem catalyst. The community manager becomes the ecosystem enablers that facilitate the networking process by connecting members. As a result, these activities will help the emerging of mutual connection and collaboration processes among members that empower open innovation among startups members. The multiple-case design makes the study conclusions might be difficult to generalize. Future research, including quantitative studies, will help the conclusions examination and the knowledge enrichment of start-ups' open innovation process. This paper will enrich the knowledge concerning how Co-working spaces member seizing opportunities that lead to the open innovation process.

Ad-hoc networks consist of a set of mobile nodes with a restricted power supply resources that can communicate with each other without any established infrastructure or centralized administration. The loss of some nodes may cause significant topological changes, undermine the network operation, and affect the lifetime of the network. This paper discusses the energy consumption problem and summaries the existing power saving techniques in ad-hoc wireless networks. The main objective of this paper is to introduce a new power aware multi-path node disjoint routing scheme based on the Dynamic Source Routing protocol (DSR), which can prolong MANETs lifetime, reduce routing delay and increase the reliability of the packets reaching its destination. Therefore, a comprehensive study of DSR protocol has been drawn using NS-2 simulator, to evaluate the performance of DSR as a routing strategy and investigate its efficiency in saving wireless networks resources, as a prelude to avoid its performance shortcomings in our proposed routing scheme. Keywords: Power aware protocol, node disjoint, network simulation 2, multipath routing, Dsr protocol, ad-hoc network.

The last decade has witnessed a steep growth in multimedia traffic due to real-time content delivery such as in online games and video conferencing. In some contexts, MANETs play a key role in the hyperconnectivity of everything in multimedia services. In this context, this work proposes a new scheduling approach based on context-aware mobile nodes for their connectivity. The contribution relies on reporting not only the locations of devices in the network but also their movement identified by sensors. In order to illustrate this approach, we have developed a novel agent-based simulator called MASEMUL for illustrating the proposed approach. The results show that a movement-aware scheduling strategy defined with the proposed approach has decreased the ratio of channel interruptions over another common strategy in mobile networks.

Paulo Coelho is an eminent Brazilian writer of the present times. His novels reflect his deep understanding of mythology and mysticism and are a blend of tradition and modernity. Woman plays a significant role in the metamorphosis of the protagonist in Coelho’s novels. This paper intends to study the role of woman in his novel The Zahir, in the light of Campbell’s theory of Initiation in his seminal work The Hero with a Thousand Faces. Campbell’s theory of Initiation accords a central position to woman. She performs various roles and becomes instrumental in bringing about the transformation of the hero. The more the hero initiates into his adventure, the more fascinating does he find the woman, changing herself in accordance with the needs of the hero as dictated by destiny Initially, woman in The Zahir seems to hold a subordinate position. She is even regarded as a mere commodity by the hero. But as the narrative develops, the role of the woman, true to Campbell’s remark undergoes a series of transfigurations, the deeper the hero initiates into his inner quest the subtler the woman becomes. From a mere commodity the woman transfigures into a guide, from a guide into a divine energy, capable of bringing about the inner transformation of the hero.

The Relationship

The article revolves around the doctrine of precedent within the so-called European legal space, wondering whether and to what extent we can speak of a convergence towards a stare decisis model boosted by the harmonizing role of the Court of Justice of the European Union. The article argues that although there are still some differences between civil law and common law legal systems they regard more the style of reasoning and the deep understanding of the relationship between the present decision of a court and past judicial decisions than the very existence of the constraints of the latter upon the former. The article concludes that a sort of mechanism of stare decisis has in fact been created, even though, on the one hand, uncertainty remains as to the way in which the binding force of a precedent concretely operates in the system, and on the other hand, this mechanism relates exclusively to the relationships between past and future decisions of higher courts (horizontal effect). This change, far from being a shift towards a truly judge-made law system or a consequence of the final abandonment of the dictates of the rule of law, enhances legal certainty contributing to the fundamental requirement of stability of law as a feature of the ideal of the rule of law.

Wireless network technically, refers to the category of network in which communication is carried out without using wires. In modern era wireless network has great importance because the communication is taking place with the use of radio waves. Thus, the use of ad-hoc network starts yielding a great importance in variety of applications. The certain research work is carried out in this particular field. MANET is a constructed from various mobility in the form of mobile nodes and anytime without any need of fixed infrastructure. MANET can be made on fly due to lack of fixed infrastructure. MANET is numerous threats types of attacks due to dynamic changing topologies and wireless medium. Security of the MANET becomes one of the challenging tasks. Black hole attacks is the main type of attack that are possible in MANET. Black hole node not forward any data packets to the neighbour node instead it drops all the data packets. Black hole attacks are bit hard to detect due to lack of centralized access. This research work concentrates to enhance the security of MANET by identifying and blocking black hole assaults from occurring. A reactive routing system such as Ad-Hoc on Demand Distance Vector has previously been used to address security problems in the MANET (AODV). Various attack types were investigated, and the consequences of these assaults were detailed by describing how MANET performance was disrupted. Network Simulator 3 (NS3) is used for the simulation process.
